Description: BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an image output control method and apparatus which can obtain a desired reproduced image using image data recorded in an information storage medium, such as a floppy disk, a card memory or the like, and which can edit data of the information recording medium, to a recording medium recording an image data file, and to a recording medium storing an image output control program. Description of the Related Art There is an extra-print service of photographs as a conventional general method for reproducing image data possessed by the customer. In the extra-print service of photographs, the customer brings in a semitransparent negative cover (negative holder) having a developed film accommodated thereon to a development laboratory or the like by writing the number of extra prints of each image, or marks. The development laboratory provides extra prints of a desired image to be reproduced (printed) by specifying the image. Recently, a photo CD (compact disk) system in which an image on a film is read, read image data is written in a CD-ROM (read-only memory), and the image data is read from the CD-ROM and is reproduced/displayed on an image display device is being utilized. In the photo CD system, a computer system reads image data recorded in a CD-ROM, and outputs the read image data using a high-picture-quality printer to provide a print image. Since the high-picture-quality printer is too expensive to be possessed by the customer, a print image is generally obtained by asking a development laboratory or the like to perform a print service. When asking a print service, the customer generally gives a CD-ROM, and a memo containing information for specifying image data recorded in the CD-ROM (such as the number of the corresponding image confirmed on an index print or the like). In accordance with improvement in the computer technology, diffusion of personal computers, and diffusion of image input devices, such as digital cameras and the like, the user can easily deal with high-definition digital image data. Such image data is recorded in a predetermined information recording medium in one of various kinds of image filing formats, such as TIFF, PICT, JPEG (Joint Photographic Experts Group), RAW and the like, and is usually output from a printer connected to a computer owned by the user. However, the printer owned by the user cannot, in some cases, provide a satisfactory print. In order to solve such a problem, a print service which can output/reproduce image data recorded in an information recording medium in the above-described manner using a high-performance printer is available at a development lavoratory, a photo studio, a DPE shop or a personal-computer shop. In order to obtain such a service, the customer must ask a print-service shop to provide prints by giving image data. Recently, it is possible to ask prints by transmitting image data via a communication network. However, a print service is usually performed by providing a print-service shop with an information recording medium where image data is recorded. When the customer asks a print service of image data recorded in an information recording medium in the above-described manner, the customer must assign a desired image from among image data recorded in the information recording medium. For that purpose, the customer must provide a print-service shop with a memo or the like describing the number or the name of the image. The print service shop must provide a print of the image by selecting the desired image from among the image data recorded in the information recording medium based on the number or the name of the image described in the memo or the like by performing a manual operation. In general, a computer system for performing the above-described print service requires a complicated operation. Accordingly, it is not easy for an ordinary shop worker to provide a print by selecting an image to be printed. In addition, since it is necessary to select a desired image from among image data recorded in an information recording medium, a manpower is required for providing a print, thereby increasing a time period for providing the print. It is known from US-A-5,258,880 to reproduce images from a video tape in which print data has been added in respect of selected pictures by an operator. During reproduction, the tape is scanned and stopped at each data area containing a picture and print data for the picture and the picture is then printed. Aspects of the present invention are set out in the appended claims. An embodiment provides an an image reproducing method in which a print of a desired image can be promptly obtained by automatically specifying the image from among images recorded in an information recording medium. An information-recording-medium-data editing method in which image data is recorded or erased, or image-reproduction instruction data is provided or deleted in an information recording medium by accessing is described. A system including an image input device, a personal computer and the like as well as an information-recording-medium-data editing unit which adopts this editing method is also described. In this case, it is possible to record new image data or delete image data which becomes unnecessary in the information recording medium, so that the capacity and the like of the information recording medium can be effectively utilized. However, when editing data in the information recording medium, a reproduction error may be produced when reproducing an image unless attention is paid to processing of recording/deleting image data and processing of instructing (selecting/not selecting) image data to be reproduced. For example, when image data recorded in the information recording medium and instructed to be reproduced in accordance with image-reproduction instruction data is deleted from the image recording medium because of some reason, and processing of disabling image-reproduction instruction data for the deleted data is not performed, image data instructed to be reproduced is not actually present in the information recording medium, and an image reproducing operation is terminated as an error. This indicates that the image reproducing operation is terminated in a state of abnormality when automatically performing image reproduction, resulting in a fatal operational error. A disclosed embodiment comprises an image output control apparatus including reading means for reading image-reproduction instruction data for instructing whether or not image data is to be reproduced recorded in an information recording medium storing the image data and the image-reproduction instruction data so that the the image-reproduction instruction data specifies an image for which image reproduction is instructed, and that the specified image data can be selectively output based on the image-reproduction instruction data, generation means for performing image reproduction for output by reading necessary image data from the information recording medium in accordance with the read image-reproduction instruction data, and skip means for skipping an operation of outputting an image corresponding to image data for which the image-reproduction instruction data is provided when that image data is absent in the information recording medium. The foregoing and other objects, advantages and features of the present invention will become more apparent from the following description of the preferred embodiment taken in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Image filing methods and image reproducing methods will now be described in detail with reference to the drawings. Provision of image-reproduction instruction data within each image data FIGS. 1(a) - 1(c) illustrate a format of filing images in an information recording medium according to a first example of the present invention. In the first example as shown in FIG. 1(a), the information recording medium is mapped into four independent areas, i.e., a reserved region, a file allocation table region, a root directory region, and a file region. In the reserved region, the number of entries within a root directory, the size of the reserved region, and the size of a file allocation table (FAT) in the information recording medium are recorded. In the file allocation table, the state of use of an information recording medium space in the file region of the information recording medium is recorded. In the root directory, directory-entry information indicating information relating to the name, the size, the position and the like of each file recorded in the information recording medium. In the file region, actual image data and image-reproduction instruction data are recorded. As shown in FIG. 1(b), image-reproduction instruction data and image data are recorded in the same file. For the convenience of explanation, this file is named "IMGxxx". Different characters, numerals or the like are allocated in 'xxx' in order to discriminate a plurality of images. Image-reproduction instruction data is recorded in the head of the file followed by image data. Image data is recorded in the format of JPEG data. In the JPEG format, original image data is recorded by being compressed. As shown in FIG. 1(c), information for restoring the compressed image data into the original image data is recorded as header information constituting a part of the image data. The header information includes, for example, information relating to the size of the image. FIG. 2 illustrates an image reproduction system (apparatus) 10 which executes an image reproduction method according to the first example. The image reproduction apparatus (system) 10 automatically selects desired image data from among image data recorded in an information recording medium 11, and performs reproduction output (printing) of an image represented by the selected image data. A CF (compact flash-memory card) is used as the information recording medium 11. The information recording medium 11 is not limited to the CF. For example, a floppy disk, a CD-R (CD-recordable), a DVD (digital video disk) or the like may also be used. The image reproduction system (apparatus) 10 includes a data reading unit 12 for reading recorded data, comprising image-reproduction instruction data and image data, recorded in the information recording medium 11, and outputting the recorded data to a bus 16, a system control unit 15 for controlling the operations of the entire system by controllling respective units of the image reproduction system 10, an image reproduction processing unit 14 for receiving image data read by the data reading unit 12 under the control of the system control unit 15 and output to the bus 16, and converting the image data into reproduction output data for performing reproduction output and outputting the reproduction output data, and an image reproducing unit 13 for receiving the reproduction output data to perform reproduction output (printing). The system control unit 15 includes, of course, a CPU (central processing unit), a ROM, a RAM (random access memory) and the like. Next, a description will be provided of the image reproduction system (apparatus) 10 of the first example. FIG. 3 is a flowchart illustrating the operation of the image reproduction system 10. A program represented by the flowchart is set in the RAM, a hard disk or the like of the system control unit 15 of the image reproduction system 10. When the image reproduction system 10 has started to operate, for example, by turning on the power supply, the operational flow is read and executed. First, in step 300, it is determined if the information recording medium 11 is set in the data reading unit 12. If the result of the determination in step 300 is affirmative, the process proceeds to step 301, where the leading IMGxxx file from among files recorded in the information recording medium 11 shown in FIGS. 1(a) - 1(c) is read by the data reading unit 12. Then, in step 302, it is determined if image-reproduction instruction data recorded in the read IMGxxx file is in an on-state. The image-reproduction instruction data is allocated to the leading 1 byte of the IMGxxx file. If the value of the image-reproduction instruction data equals 1 in decimal notation, that indicates an on-state, and other values indicate an off-state. At the input side, this data is assigned using input means, such as a personal computer, a digital camera or the like. This data is recorded while determining necessity of reproduction during a photographing operation. The recorded data is read, and is added to an image to be reproduced while confirming necessity of reproduction. Although control at the recording side is mainly described, input means for recording an image in a recording medium, such as a digital camera, in a format described in the first example is also possible. In such a case, input control of an image, control of recording recording/reproduction instruction data input corresponding to the input image in a recording medium in the format described in the first example, and control of also recording a corresponding recording control program in the recording medium are also performed. Accordingly, by analizing the leading 1-byte data of the IMGxxx file, the state of the image-reproduction instruction data can be easily confirmed. When the image-reproduction instruction data is in an off-state (not in an on-state), the process proceeds to steps 305 and 306. When another IMGxxx file is present, the process returns to step 302. When the image-reproduction instruction data is in an on-state, the process proceeds to step 303, where, as described above, the image reproduction processing unit 14 performs image reproduction output processing for image reproduction output (printing) for image data stored in the IMGxxx file to generate image reproduction output data. In step 304, the generated image reproduction output data is reproduced and output by the image reproduction unit 13. JPEG data is used as image data, and the image reproduction unit 13 uses an ink-jet printer as an image reproducing device. Accordingly, the image reproduction processing unit 14 performs processing of obtaining RGB data by decompressing image data stored as JPEG data, color processing, resolution conversion processing, halftoning processing, and the like. Since each of such processing is well known, further description thereof will be omitted. Then, in step 305, it is determined if the next IMGxxx file is present by accessing the information recording medium 11. If the result of the determination in step 305 is affirmative, the process proceeds to step 306, where the next IMGxxx file is read, and the process then returns to step 302. If the result of the determination in step 305 is negative, the operation of the image reproduction system is terminated. As described above, in the image reproduction system desired image data is automatically selected from the information recording medium where the data is recorded according to the image filing method of the first embodiment, and image reproduction output is performed. Accordingly, by executing the image filing method and the image reproducing method of the present invention, desired image data recorded in the information recording medium can be automatically reproduced and output without assigning the desired image using a memo or the like. Although in the first example, JPEG data is used as image data, image data is not limited to JPEG data. For example, data conforming to TIFF, PICT or the like may also be used. RAW data may also be used. In this case, however, it is necessary to record information relating to image reproduction in the information recording medium together with image data. When using data having a format other than the JPEG format, it is only necessary to change processing performed by the image reproduction processing unit 14 depending on each image data. The example is not limited to a specific type of image data being used. Although in the first example, an ink-jet printer is used as the image reproducing device, the device is not limited to such a printer. For example, a sublimation-type thermal printer or a silver-halide-film printer may be used. Alternatively, a soft copy display device, such as a CRT (cathode-ray tube), an LCD (liquid-crystal display), a plasma display or the like, may be used. When using such a device, also, it is only necessary to change processing in the image reproduction processing unit 14 so as to perform processing corresponding to a printer or a soft copy display device being used. Accordingly, the present example may use any appropriate image reproducing device. In the firstexample, image-reproduction instruction data is recorded in the leading 1-byte region of the file where the image-reproduction instruction data and image data are recorded, and the image-reproduction instruction data is in an on-state when the value of the image-reproduction instruction data equals 1 in decimal notation, and is in an off-state in other cases. However, the present example is not limited to such an approach. For example, image-reproduction instruction data may be recorded in the leading 2-byte region of the file, or in the last 1-byte region of the file. In the case of image data having an image header, such as JPEG image data, a partial region of the image header is opened for extension by the user. In such a case, image-reproduction instruction data may be recorded using a part of the extended region. Image-reproduction instruction data is not necessarily in an on-state when its value equal 1, and in an off-state in other cases, as in the first example. Although the position, the size and the contents of recorded image-reproduction instruction data in the file may be arbitrary as described above, it is determined whether or not image data included within the file is to be reproduced by determining how the contents of the image-reproduction instruction data correspond to predetermined contents of recording by analyzing recorded data at a corresponding position based on the position and the size of the recorded image-reproduction instruction data in the file. Accordingly, it is only necessary to record image data and image-reproduction instruction data instructing whether or not the image data is to be reproduced, so that the position, the size, the contents and the order of recording of recorded image-reproduction instruction data may be arbitrarily set. Second example provision of a particular mark for the name of a recorded file In FIG. 1(b) illustrating the first example, image data and image-reproduction instruction data for instructing whether or not the image data is to be reproduced are recorded in a recording file. However, there is disclosed a method of providing a particular mark for the name of a recording file. FIGS. 4(a) and 4(b) are diagrams illustrating a format of filing images in an information recording medium according to a second example. In the second example, also, as shown in FIG. 4(a), the information recording medium is mapped into four independent areas, i.e., a reserved region, a file allocation table region, a root directory region, and a file region. The second example differs from the first example in that a file name recorded in a root directory has information as image-reproduction instruction data. In the second example, 'DP' is added to the name of image data to be subjected to image reproduction. That is, if the file name is 'xxxDP', it indicates that an image represented by image data corresponding to that file name is to be reproduced. If the file name is only 'xxx', it indicates that an image represented by image data corresponding to that file name is not to be reproduced. An extender in the name may be used as a specific identifier in order to discriminate between an image to be reproduced and an image not to be reproduced. The image reproduction system 10 for performing image reproduction according to the second example has the same configuration as the image reproduction system 10 of the first example. Next, a description will be provided of the image reproduction system 10 of the second example. FIG. 5 is a flowchart illustrating the operation of the image reproduction system 10. A program represented by the flowchart is set in the RAM, a hard disk or the like of the system control unit 15 of the image reproduction system 10. When the image reproduction system 10 has started to operate, for example, by turning on the power supply, the operation of the flowchart is read and executed. First, in step 500, it is determined if the information recording medium 11 is set in the data reading unit 12. If the result of the determination in step 500 is affirmative, the process proceeds to step 501, where the data reading unit 12 refers to the contents of the root directory recorded in the information recording medium 11 to determine if a 'xxxDP' file is present. If the result of the determination in step 501 is negative, the operation is terminated. If the result of the determination in step 501 is affirmative, the process proceeds to step 502, where the leading 'xxxDP' file in the file region is read (see FIG. 4(b)). Then, the image reproduction processing unit 14 performs image reproduction output processing for image reproduction output (printing) for image data stored in the 'xxxDP' file to generate image reproduction output data. In step 504, the generated image reproduction output data is reproduced and output by the image reproduction unit 13. JPEG data is used as image data, and the image reproduction unit 13 uses an ink-jet printer as an image reproducing device. Accordingly, the image reproduction processing unit 14 performs processing of obtaining RGB data by decompressing image data stored as JPEG data, halftoning processing, resolution conversion processing, halftoning processing, and the like. Then, in step 505, it is determined if the next 'xxxDP' file is present by accessing the information recording medium 11. If the result of the determination in step 505 is affirmative, the process proceeds to step 506, where the next IMGxxx file is read, and the process then returns to step 503. If the result of the determination in step 505 is negative, the operation of the image reproduction system of the second embodiment is terminated. As described above, in the image reproduction system of the second example, desired image data is automatically selected from the information recording medium where the data is recorded according to the image filing method, and image reproduction output is performed. Accordingly, by executing the image filing method and the image reproducing method desired image data recorded in the information recording medium can be automatically reproduced and output without assigning the desired image using a memo or the like. Although in the second example, also, JPEG data is used as image data, image data is not limited to JPEG data. For example, data conforming to TIFF, PICT or the like may also be used. RAW data may also be used. In this case, however, it is necessary to record information relating to image reproduction in the information recording medium together with image data. When using data having a format other than the JPEG format, it is only necessary to change processing performed by the image reproduction processing unit 14 shown in the second example depending on each image data. The example is not limited to a specific type of image data being used. Although in the second example, also, an ink-jet printer is used as the image reproducing device, the example is not limited to such a printer. For example, a sublimation-type thermal printer or a silver-halide-film printer may be used. Alternatively, a soft copy display device, such as a CRT, an LCD, a plasma display or the like, may be used. When using such a device, also, it is only necessary to change processing in the image reproduction processing unit 14 so as to perform processing corresponding to a printer or a soft copy display device being used. Accordingly, the method may use any appropriate image reproducing device. In the second example, 'DP' is added to the name of image data to be subjected to image reproduction, in order to indicate that an image of that file is to be reproduced. However, the method is not limited to such an approach. It is only necessary that a file name recorded in the root directory has information as image-reproduction instruction data. Accordingly, the method may be easily executed even if any other name or mark is used. As described above, the image reproduction system checks the feature of a file name which may be arbitrarily determined in advance, and determines if that feature corresponds to a predetermined feature, to determine whether or not image data included in that file is to be reproduced. Accordingly, it is only necessary to record a feature indicating image-reproduction instruction data in a file name, so that the feature used, i.e., a name, a mark, a symbol or the like may be arbitrarily set. Third example: provision of a file storing a file name where image data to be subjected to image reproduction is present within a file region Next, a third example will be described. FIGS. 6(a) - 6(c) are diagrams illustrating a format of filing images in an information recording medium according to the third embodiment. In the third example, also, as shown in FIG. 6(a), the information recording medium is mapped into four independent areas, i.e., a reserved region, a file allocation table region, a root directory region, and a file region. The third example differs from the second example; mainly in that two kinds of files are recorded in the file region. One is a file having an image-data file to be subjected to image reproduction as the contents of recording. In the third example, the name of such a file is represented by 'DPFxxx' (see FIG. 6(c)). Another is a file having image data itself as the contents of recording. In the third example, the name of such a file is represented by 'IMGxxx'. Thus, a file name having image data to be subjected to image reproduction is recorded in the 'DPFxxx' file. The image reproduction system 10 for performing image reproduction according to the third example has the same configuration as the image reproduction system 10 of the second example. Next, a description will be provided of the image reproduction system 10 of the third example. FIG. 7 is a flowchart illustrating the operation of the image reproduction system 10. A program represented by the flowchart is set in the RAM, a hard disk or the like of the system control unit 15 of the image reproduction system 10. When the image reproduction system 10 has started to operate, for example, by turning on the power supply, the operation of the flowchart is read and executed. First, in step 700, it is determined if the information recording medium 11 is set in the data reading unit 12. If the result of the determination in step 700 is affirmative, the process proceeds to step 701, where the data reading unit 12 refers to the contents of the root directory recorded in the information recording medium 11 to determine if a 'DPFxxx' file is present. If the result of the determination in step 701 is negative, the operation is terminated. If the result of the determination in step 701 is affirmative, the process proceeds to step 702, where the leading 'DPFxxx' file in the file region is read (see FIG. 6(c)). Then, in step 703, the first file name 'IMGxxx' stored in the read 'DPFxxx' file is read. Then, in step 704, image data corresponding to the 'IMGxxx' file read in step 703 (see FIG. 6(b)) is read. Then, in step 705, the image reproduction processing unit 14 performs image reproduction output processing for image reproduction output (printing) for the image data read in step 704 to generate image reproduction output data. In step 706, the generated image reproduction output data is reproduced and output by the image reproduction unit 13. JPEG data is used as image data, and the image reproduction unit 13 uses an ink-jet printer as an image reproducing device. Accordingly, the image reproduction processing unit 14 performs processing of obtaining RGB data by decompressing image data stored as JPEG data, color processing, resolution conversion processing, halftoning processing, and the like. Then, in step 707, it is determined if the next 'IMGxxx' file is present in the 'DPFxxx' file currently being accessed (see FIG. 6(c)). If the result of the determination in step 707 is affirmative, the process proceeds to step 708, where the next IMGxxx file is read, and the process then returns to step 704. If the result of the determination in step 707 is negative, the process proceeds to step 709, where it is determined if another 'DPFxxx' file is present by accessing the information recording medium 11. If the result of the determination in step 709 is affirmative, the process proceeds to step 710, where the next 'DPFxxx' file is read, and the process then returns to step 703. If the result of the determination in step 709 is negative, the operation of the image reproduction system is terminated. As described above, in the image reproduction system of the third example, desired image data is automatically selected from the information recording medium where the data is recorded according to the image filing method of the third embodiment, and image reproduction output is performed. Accordingly, by executing the image filing method and the image reproducing method of the present invention, desired image data recorded in the information recording medium can be automatically reproduced and output without assigning the desired image using a memo or the like. Although in the third example, also, JPEG data is used as image data, image data is not limited to JPEG data. For example, data conforming to TIFF, PICT or the like may also be used. RAW data may also be used. In this case, however, it is necessary to record information relating to image reproduction in the information recording medium together with image data. When using data having a format other than the JPEG format, it is only necessary to change processing performed by the image reproduction processing unit 14 shown in the third embodiment depending on each image data. The method is not limited to a specific type of image data being used. Although in the third example, also, an ink-jet printer is used as the image reproducing device, the device is not limited to such a printer. For example, a sublimation-type thermal printer or a silver-halide-film printer may be used. Alternatively, a soft copy display device, such as a CRT, an LCD, a plasma display or the like, may be used. When using such a device, also, it is only necessary to change processing in the image reproduction processing unit 14 so as to perform processing corresponding to a printer or a soft copy display device being used. Accordingly, any appropriate image reproducing device may be used. In the third example, two kinds of files are recorded in the file region. One is a file having image data file to be subjected to image reproduction as the contents of recording, and another is a file having image data itself as the contents of recording, having file names of 'DPFxxx' and 'IMGxxx', respectively. The file names are limited to such names, but any file names may be adoped provided that the two kinds of files can be identified. As described above, the image reproduction system checks the feature of a file name which may be arbitrarily determined in advance, and determines if that feature corresponds to a predetermined feature, to determine whether the contents of that file indicate image data or a file name to be subjected to image reproduction. By selectively accessing a file where the file name to be subjected to image reproduction is stored, the file name stored in that file is read, the file corresponding to that file name is read, and image reproduction is performed for image data stored in that file. Although in the third example, a file name is used as means for discriminating a image-reproduction instruction data file storing a file name to be subjected to image reproduction, the method is not limited to such an approach. For example, a file format shown in FIGS. 8(a) - 8(c) may be used as an image filing method. As is apparent from FIG. 8(a), in this case, an image-reproduction instruction data file is stored at the leading position of the file region as a particular file. This information is recorded in the root directory and is referred to. That is, when executing the method in this manner, the leading file of the file region of the information recording medium corresponds to the image reproduction instruction data file. Hence, in the image reading method by reading information recorded in the leading file of the file region of the information recording medium, a recorded file including image data to be subjected to image reproduction can be easily selected. Furthermore, by preparing a file region dedicated for an image-reproduction instruction data file and recording that data file in the root directory, it is also possible to selectively access the image-reproduction instruction data file. Accordingly, in such a case, also, the present method can be executed. In this case, although a flowchart is omitted, the image-reproduction instruction data file shown in FIGS. 8(a) and 8(c) may be searched for instead of the DPFxxx file shown in step 703 in FIG. 7, and image data represented by IMGxxx shown in FIG. 8(b) may be accessed whenever necessary. As described above, in the image reproduction system and apparatus, by analizing recorded data at a corresponding position based on the position and the size of predetermined image-reproduction instruction data in the information recording medium, and determining how the contents of that data correspond to predetermined contents of recording, it is determined whether or not image data recorded in the information recording medium is to be reproduced. Accordingly, the image output operation executed in the image reproduction system and apparatus differs in each of the examples in accordance with the data recording format of the information recording medium. In each of the above-described examples, a program represented by an operational flow corresponding to a recording format used in the example is set in the RAM or the hard disk of the system control unit 15 of the image reproduction system 10. Dealing with multiple formats The present disclosure is not limited to the configurations of the above-described examples. For example, an operational flow can be set or reset within an image reproduction system utilizing an information recording medium or a communication network. FIG. 10 illustrates an operational flow in such a case. The program represented by this operational flow is set in the RAM or the hard disk of the system control unit 15 of the image reproduction system 10. When the image reproduction system 10 starts, for example, by turning on the power supply, the program represented by this operational flow is read and executed. In this case, an image file is stored in a format corresponding to the stored program. That is, when a plurality of kinds of main formats are present in a state in which standards are not unified, and a medium in which data is recorded with a certain format is loaded, it is possible to perform processing appropriate for that format irrespective of the format. For example, when formats shown in FIGS. 1(a) - 1(c), 4(a) and 4(b), 6(a) - 6(c), and 8(a) - 8(c) are present, one of the flowcharts shown in FIGS. 3, 5 and 7 (the flowchart corresponding to FIGS. 8(a) - 8(c) is omitted) corresponding to the format is stored in PRG shown in FIG. 9(a). A fourth example will now be described with reference to FIG. 10. First, in step 1001, it is determined if the information recording medium 11 is set in the data reading unit 12. If the result of the determination in step 1001 is affirmative, the process proceeds to step 1002, where it is determined if an image output control program PRG is stored in the set information recording medium 11 (see FIG. 9(a)). If the result of the determination in step 1002 is affirmative, the process proceeds to step 1003, where the image output control program PRG is set within the system control unit 15 of the system. If the result of the determination in step 1002 is negative, the process proceeds to step 1004, where the system performs an operation in accordance with an image output control program set in the system control unit 15 of the system (a default program, for example, one of the programs represented by the flowcharts shown in FIGS. 3, 5 and 7 may be used). Upon completion of a series of operations, the process returns to this operational flow. Then, in step 1005, the set information recording medium 11 is discharged to terminate the process. In order to execute the fourth example, an image output control program must be recorded in the information recording medium 11. FIGS. 9(a) - 9(c) illustrate an image recording medium format of the information recording medium 11. The image output control program is recorded in the file region in the name of PRG. In the fourth example, by confirming if the file having that name is present, it is confirmed that the image output control program is stored in the information recording medium. As described above, if the type of a program corresponds to a format, the type of a program (for example, one of the programs shown in FIGS. 3, 5 and 7) and the type of the format corresponding to the program (for example, one of formats shown in FIGS. 1(a) - 1(c), 4(a) and 4(b), 6(a) - 6(c), and 8(a) - 8(c)) are identified according to the name of the program. It is only necessary to store an image output control program in the information recording medium 11, and to provide the image reproduction system and apparatus with means for accessing the program. For example, if the above-described file is present at a determined position, and that position is set in the image reproduction system and apparatus, it is also possible to access the image output control program of the information recording medium based on that information. Direct access to a program In the fourth example, when an image output control program is stored in an information recording medium, image output control is performed by first storing the image output control program in the memory or the like of the system control unit of the image reproduction system. However, the method is not limited to such an approach. For example, it is also possible to output an image by performing image output control by directly accessing the program stored in the information recording medium. FIG. 11 illustrates an operational flow in such a case. The operation of this case is substantially the same as shown in FIG. 10, except performing direct access to the image output program stored in the information recording medium. Hence, further description thereof will be omitted. In step 1103, output control is performed based on a program stored in the medium. If the program is not stored in the medium as a result of determination in step 1102, the process proceeds to step 1104, where output control is performed based on an image output program stored in the apparatus. Provision of a plurality of slots FIG. 13 is a diagram illustrating the configuration of an image reproduction system (apparatus) according to a fifth example. The basic configuration of the apparatus is the same as the configuration in the first example shown in FIG. 2. In the fifth example a slot for each information recording medium is provided in the data reading unit. One of the slots is for an information recording medium for recording image data and information-reproduction instruction data for instructing whether or not the image data is to be reproduced, as in the first embodiment. Another slot is for a medium storing a program for controlling an image output operation of the image reproduction system. FIG. 12 illustrates the operational flow of the fifth example. This operational program is set in the RAM, the hard disk or the like of the system control unit of the image reproduction system. When the image reproduction system has started, for example, by turning on the power supply, the operational flow is read and executed. First, in step 1200, it is determined if the information recording medium 11 is mounted in a slot. If the result of the determination in step 1200 is affirmative, the process proceeds to step 1201, where it is determined if the information recording medium 11 is set in the slot for program of the data reading unit. If the result of the determination in step 1201 is affirmative, the process proceeds to step 1202, where it is determined if an image output control program is present in the information recording medium 11. If the result of the determination in step 1202 is affirmative, the process proceeds to step 1203, where the image reproduction system is controlled by the image output control program stored in the information recording medium 11, to execute image output. If the result of the determination in step 1201 or 1202 is negative, it may be determined that only a recording medium for image data is set on another slot for image data, or that a medium for image data is erroneously set in the slot for a program, and the process proceeds to step 1204, where the image reproduction system is controlled by an image output control program stored in the system in advance, to execute image output. Then, the process is terminated. When both a medium for a program and a medium for image data are mounted in the corresponding slots, image reproduction processing is, of course, selectively performed based on image-reproduction instruction data stored in the set medium for image data in the above-described manner, based on the program. Example of image reproduction system Next, a description will be provided of the structure of a printer of the image reproduction system to which any one of the above examples can be applied. The configurations of a laser-beam printer and an ink-jet printer to which any one of the examples can be applied will be described with reference to FIGS. 14 and 15, respectively. The printer to which any one of the examples is applied is not limited to a laser-beam printer or an ink-jet printer, but any other appropriate printer may, of course, be adopted. FIG. 14 is a cross-sectional view illustrating the configuration of a first recording apparatus, for example, a laser-beam printer (LBP). In FIG. 14, a main body 1500 of the LBP (printer) receives and stores printing information (character codes or the like), form information, a macrocommand or the like supplied from a host computer connected to the printer, forms character patterns, a form pattern or the like in accordance with the information, and forms an image on recording paper, serving as a recording medium. A printer control unit 1000 controls the entirety of the LBP main body 1500 and analyzes character information or the like supplied from the host computer. The printer control unit 1000 mainly converts character information into a video signal representing corresponding character patterns, and outputs the video signal to a laser driver 1502. The laser driver 1502 is a circuit for driving a semiconductor laser 1503, and performs on-off switching of a laser beam 1504 emitted from the semiconductor laser 1503 in accordance with the input video signal. The laser beam 1504 is deflected in a direction perpendicular to the plane of FIG. 14 by a rotating polygonal mirror 1505 to scan and expose an electrostatic drum 1506. An electrostatic latent image of the character patterns is thereby formed on the electrostatic drum 1506. The electrostatic latent image is developed by a developing unit 1507 disposed around the electrostatic drum 1506, and the developed image is transferred onto recording paper. A cut sheet is used as the recording paper. Cut sheets of the recording paper are accommodated in a sheet cassette 1508 mounted in the LBP main body 1500, and is supplied to the electrostatic drum 1506 by being received into the printer by a sheet feeding roller 1509 and conveying rollers 1510 and 1511. A color image may also be obtained according to the same configuration. FIG. 15 is an external-appearance diagram illustrating the configuration of a second recording apparatus, for example, an ink-jet recording apparatus (IJRA). In FIG. 15, a carriage HC engaging with a helical groove 5004 of a lead screw 5005 rotated in a state of being linked with forward/reverse revolutions of a driving motor 5013 via driving-force transmission gears 5011 and 5009 has a pin (not shown), and is reciprocated in directions of arrows a and b via a guide rail 5003. An ink-jet cartridge IJC including an ink tank IT and an ink-jet head IJH is mounted on the carriage HC. A sheet pressing plate 5002 presses a sheet against a platen 5000 along the carriage moving direction. The head can also output a color image. Driving is not limited to a specific method. For example, a piezoelectric method, an air flow method, a sublimation method or the like may be adopted. A photocoupler 5007, 5008 operates as home-position detection means for confirming presence of a carriage lever 5006 in this region, and performing, for example, switching of the direction of revolution of the driving motor 5013. Reference numeral 5016 represents a member which operates a cap member 5022 for capping the entire surface of the recording head. Reference numeral 5015 represents suction means for sucking the inside of the cap. The suction means 5015 performs suction recovery of the recording head via an opening 5023 provided in the cap. A cleaning blade 5017 is movable in forward and reverse directions by a member 5019. A main-body supporting plate 5018 supports the cleaning blade 5017 and the member 5019. A lever 5012 for starting suction of suction recovery is moved in accordance with the movement of a cam 5020 engaging the carriage. The driving force from the driving motor 5013 is subjected to movement control by known transmission means, such as clutch switching or the like. For each of these capping, cleaning and suction recovery, desired processing can be performed at a corresponding position by the function of the lead screw 5005 when the carriage reaches the home position side region. It is only necessary to perform a desired operation at a well-known timing. Sixth example Next, a description will be provided of a sixth example. An image reproduction method, and an image reproduction system and apparatus according to the sixth example will now be described in detail with reference to the drawings. The sixth example has the feature that the apparatus includes display means for displaying image-reproduction instruction data and image data, and that the display means displays a summary, or a mark indicating whether or not the displayed image is an image to be reproduced, or whether or not all images to be reproduced can be output based on the number of images outputtable by the apparatus. FIG. 16 illustrates an image reproduction system (apparatus) 10 which executes an image reproduction method according to the sixth example. This image reproduction apparatus (system) 10 automatically selects desired image data from among image data recorded in an information recording medium 11, and performs reproduction output (printing) of an image represented by the selected image data. In the fifth example, a CF is used as the information recording medium 11. The information recording medium 11 is not limited to the CF. For example, a floppy disk or the like may also be used. The image reproduction system (apparatus) 10 includes a data reading unit 12 for reading recorded data, comprising image-reproduction instruction data and image data, recorded in the information recording medium 11, and outputting the recorded data to a bus 16, a system control unit 15 for controlling the operations of the entire system by controllling respective units of the image reproduction system 10, an image reproduction processing unit 14 for receiving image data read by the data reading unit 12 under the control of the system control unit 15 and output to the bus 16, and converting the image data into reproduction output data for performing reproduction output and outputting the reproduction output data, an image reproducing unit 13 for receiving the reproduction output data to perform reproduction output (printing), a data processing unit 170 for analyzing the contents of image-reproduction instruction data by selectively accessing that data, and a data display unit 180 for displaying a summary of images to be reproduced in accordance with the result of the data processing unit 170. In the sixth example, a thumbnail image is displayed on the data display unit 180. However, the display is not limited to such a display. For example, the name of each image file may be displayed. FIGS. 17(a) - 17(c) illustrate a format of filing images in an information recording medium according to the sixth example. In the sixth example, the information recording medium is mapped into four independent areas, i.e., a reserved region, a file allocation table region, a root directory region, and a file region. In the reserved region, the number of entries within a root directory, the size of the reserved region, and the size of a file allocation table (FAT) in the information recording medium are recorded. In the file allocation table, the state of use of an information recording medium space in the file region of the information recording medium is recorded. In a root directory, directory-entry information indicating information relating to the name, the size, the position and the like of each file recorded in the information recording medium is recorded. In the file region, actual image data and image-reproduction instruction data are recorded. In the sixth example, at least two kinds of files are used as files to be recorded in the file region. One is a file having image data itself as the contents of recording. A file having a format of JPEG data is used. For the convenience of explanation, such a file is hereinafter named 'XXX.JPG'. The file name is not limited to this format, but any other appropriate format may be adopted provided that image files can be classified. In the JPEG format, original image data is recorded by being compressed. Information for restoring the compressed image data into the original image data is recorded as header information constituting a part of the image data. The header information includes, for example, information relating to the size of the image. Another file is a file having an image data file to be subjected to image reproduction and additional information relating to the file as the contents of recording. In the sixth embodiment, such a file is named 'AUTOPRINT.MRK'. FIG. 18 illustrates an example of the contents of recording of 'AUTOPRINT.MRK'. <PRE> CIFF_VERSION = 1.00 is header information of the file. The image data file to be subjected to image reproduction is represented by providing the following tag: <IMG SRC = "XXX.JPG">. The data file to be subjected to image reproduction is indicated within parentheses " ". CIFF_PRINT_COUNT = 1 is an example of a tag indicating additional information, and indicates, in the sixth embodiment, the number of prints of the image reproduction data file indicated immediately before the tag. Accordingly, by checking the contents of recording of AUTOPRINT.MRK, the image data file to be subjected to image reproduction and the total number of images to be reproduced can be obtained. For example, as for the 'AUTOPRINT.MRK' shown in FIG. 18, image files to be subjected to image reproduction are 'AOO.JPG' and 'A03.JPG', and the total number of images to be reproduced is 3. This file is edited using input means of a personal computer or a digital camera. This file is edited by determining whether an image is to be reproduced during a photographing operation, and also, for example, when reading recorded data and adding the read data to an image to be reproduced while confirming necessity of reproduction of the data. Next, a description will be provided of the operation of the image reproduction system (apparatus) 10 of the sixth example. FIG. 19 illustrates the operational flow of the image reproduction system 10. The program represented by the operational flow is set in a RAM, a hard disk or the like of the system control unit 15 of the image reproduction system 10. When the image reproduction system 10 has started, for example, by turning on the power supply, the operational flow is read and executed. First, in step 301, it is determined if the information recording medium 11 is set in the data reading unit 12. If the result of the determination in step 301 is affirmative, the process proceeds to step 302, where it is determined if an image to be reproduced is to be confirmed. This determination is provided in advance using a switch of the user interface. If the result of the determination in step 302 is affirmative, the process proceeds to step 310. If the result of the determination in step 302 is negative, the process proceeds to step 303. First, the case of proceeding to step 310 will be described followed by description of the case of proceeding to step 303. In step 310, the data reading unit 12 reads an AUTOPRINT.MRK file from among files recorded in the information recording medium 11. The contents of the read file are sequentially transferred to the data processing unit 170 to be analyzed. In step 311, the end of the file is confirmed. When the end of the file is not confirmed, the contents of the file are continued to be analyzed, and in step 312, it is determined if TAG" < IMG" is present. If the result of the determination in step 312 is negative, the process returns to step 311, where analysis of the contents of the file is continued while confirming the end of the file. If the result of the determination in step 312 is affirmative, the process proceeds to step 313, where the name of the image file to be subjected to image reproduction "XXX.JGP" is read from the contents of the file SRC = "XXX.JPG" recorded after the TAG"<IMG". In step 314, image data to be displayed corresponding to the image file to be subjected to image reproduction is read based on the read name of the image file to be subjected to image reproduction, and is displayed on the data display unit 180. In the sixth example, data prepared in advance as a thumbnail image is used as image data to be displayed. JPEG data is used as image data for display, and the data display unit 180 uses a CRT as the image display device. Accordingly, the data processing unit 170 performs processing of obtaining RGB data by decompressing image data for display stored as JPEG data, color processing, resolution conversion processing, and the like. When data display has been performed, the process returns to step 311, where the system continues analysis of the contents of the AUTOPRINT.MRK file while confirming the end of the file. Until the end of the file is confirmed, the analysis of the contents is performed by executing the processes of steps 311, 312, 313 and 314. The image files to be subjected to image reproduction are sequentially added to the data display unit 180 to be displayed thereon, and a summary of images are displayed. FIGS. 24(a) - 24(c) are examples of such display. When the end of the file has been confirmed in step 311, the process proceeds to step 315, where it is determined if the confirmed image is to be displayed. This determination is provided using a switch of the user interface. If the result of the determination in step 315 is affirmative, the process proceeds to step 303, where image reproduction is performed. If the result of the determination in step 315 is negative, the process is terminated. Next, a description will be provided of the case of proceeding to step 303 and performing image reproduction. In step 303, the data reading unit 12 reads an AUTOPRINT.MRK file from among files recorded in the information recording medium 11. The contents of the read file are sequentially transferred to the data processing unit 170 to be analyzed. In step 304, the end of the file is confirmed. When the end of the file is not confirmed, the contents of the file are continued to be analyzed, and in step 305, it is determined if TAG" < IMG" is present. If the result of the determination in step 305 is negative, the process returns to step 304, where the analysis of the contents of the file is continued while confirming the end of the file. If the result of the determination in step 305 is affirmative, the process proceeds to step 306, where the name of the image file to be subjected to image reproduction "XXX.JGP" is read from the contents of the file SRC = "XXX.JPG" recorded after the TAG"<IMG". In step 307, image data stored in the image file to be subjected to image reproduction is read based on the read name of the image file to be subjected to image reproduction. In step 308, the image reproduction processing unit 14 executes image reproduction output processing for image reproduction output (printing), to generate image reproduction output data. The generated image reproduction output data is subjected to reproduction output (printing) by the image reproducing unit 13. In the sixth example, JPEG data is used as image data, and the data reproducing unit 13 uses an ink-jet printer as the image reproducing device. Accordingly, the image reproduction processing unit 14 performs processing of obtaining RGB data by decompressing image data stored as JPEG data, color processing, resolution conversion processing, halftoning processing, and the like. When image reproduction output (printing) has been performed, the process returns to step 304, where the system continues the analysis of the contents of the AUTOPRINT.MRK file while confirming the end of the file. Until the end of the file is confirmed, the analysis of the contents is performed by executing the processes of steps 304, 305, 306, 307, 308 and 309. When the end of the file has been confirmed in step 304, the system terminates its operation. As described above, desired image data is automatically selected from the information recording medium where the data is recorded according to the image filing method of the sixth example, and image reproduction output is performed. Accordingly, by executing the image filing method and the image reproducing method, desired image data recorded in the information recording medium can be automatically reproduced and output without assigning the desired image using a memo or the like. Furthermore, since means for confirming an image to be reproduced is provided, it is possible to easily confirm the image to be reproduced by the user's instruction before automatically performing image reproduction. Although in the sixth example, JPEG data is used as image data and image data for display, image data is not limited to JPEG data. For example, data conforming to TIFF, PICT or the like may also be used. RAW data may also be used. In this case, however, it is necessary to record information relating to image reproduction in the information recording medium together with image data. When using data having a format other than the JPEG format, it is only necessary to change processing performed by the image reproduction processing unit 14 and the data processing unit 170 depending on each image data. The method is not limited to a specific type of image data being used. Although in the sixth example, an ink-jet printer is used as the image reproducing device, the device is not limited to such a printer. For example, a sublimation-type thermal printer or a silver-halide-film printer may be used. Although a CRT is used as the data display device, the display device is not limited to such a device. For example, an LCD, a plasma display, an LED display, or any other printer may be used. When using such a device, also, it is only necessary to change processing in the image reproduction processing unit 14 and the data processing unit 170 so as to perform processing corresponding to a printer or a soft copy display device being used. Accordingly, the method may use any appropriate image reproducing device and data display device. In the image reproduction system of the presentexample, by analizing recorded data at a corresponding position based on the position and the size of image-reproduction instruction data in a file, and determining how the contents of the data correspond to predetermined contents of recording, it is determined whether or not image data recorded in the file is to be reproduced. Accordingly, it is only necessary that image data and image-reproduction instruction data for instructing whether or not the image data is to be reproduced are recorded in the file. There is no limitation in the position, the size, the contents, the order and the like of recording. Seventh example In the above-described sixth example, a description has been provided of the case of displaying a summary of information relating to an image to be reproduced on a data display unit in order to confirm the image before reproducing the image in an image reproduction system and apparatus for automatically reproducing image data recorded in an information recording medium. In order to confirm an image to be displayed, information relating to image data recorded in the information recording medium (may be the corresponding image itself, the name of the image file, the number of the file, or the like) may be displayed, and whether or not the image is to be reproduced may also be displayed at that time. A description will now be provided of such an approach according to a seventh example. An image reproduction system according to the seventh example has the same configuration as the image reproduction system of the sixth example. The operation of the image reproduction system 10 in the seventh example will now be described. FIG. 20 illustrates the operational flow of the image reproduction system 10 . A part of the operational flow of the seventh example is the same as the operational flow shown in FIG. 19. Since processes having the same step numbers as in FIG. 19 perform the same operations, a further description thereof will be omitted. The seventh example differs from the sixth example mainly in the operational flow of confirming an image to be reproduced. Hence, the operational flow of such a portion will be particularly described. As for the operational flow which is not described in the seventh example, refer to the foregoing description. This operational flow is set in the RAM, the hard disk or the like of the system control unit 15 of the image reproduction system 10. When the image reproduction system 10 has started, for example, by turning on the power supply, the operational flow is read and executed. First, in step 301, it is determined if the information recording medium 11 is set in the data reading unit 12. If the result of the determination in step 301 is affirmative, the process proceeds to step 302, where it is determined if an image to be reproduced is to be confirmed. This determination is provided in advance using a switch of the user interface. If the result of the determination in step 302 is affirmative, the process proceeds to step 501. If the result of the determination in step 302 is negative, the process proceeds to step 303. In step 303, image data is reproduced from the information recording medium in accordance with the contents described in an AUTOPRINT.MRK file. This operational flow is the same as in the sixth example. A description will now be provided of the case of proceeding to step 501. In step 501, the first image data in the information recording medium is read. Then, in step 502, the data processing unit 170 performs processing for data display. Then, in step 503, the image data is displayed on the data display unit 180. In the seventh example, JPEG data is used as image data, and the data display unit 180 uses a CRT as the image display device. Accordingly, the data processing unit 170 performs processing of obtaining RGB data by decompressing image data stored as JPEG data, color processing, resolution conversion processing, and the like. Next, in step 504, the file name of the image data displayed on the data display unit 180 is read. Then, in step 505, the data reading unit 12 reads an AUTOPRINT.MRK file from among files recorded in the information recording medium 11. The contents of the read file are sequentially transferred to the data processing unit 170 to be analyzed. In step 506, the end of the file is confirmed. When the end of the file has been confirmed, the process proceeds to step 511. The operation starting from step 511 will be described later. When the end of the file is not confirmed, the contents of the file are continued to be analyzed, and in step 507, it is determined if TAG" < IMG" is present. If the result of the determination in step 507 is negative, the process returns to step 506, where the analysis of the contents of the file is continued while confirming the end of the file. If the result of the determination in step 507 is affirmative, the process proceeds to step 508, where the name of the image file to be subjected to image reproduction "XXX.JGP" is read from the contents of the file SRC = "XXX.JPG"> recorded after the TAG"<IMG". In step 509, it is determined if the name of the read image file to be subjected to image reproduction coincides with the name of the image data file currently being displayed. If the result of the determination in step 509 is negative, the process returns to step 506, where the analysis of the contents of the file is continued while confirming the end of the file. If the result of the determination in step 509 is affirmative, the process proceeds to step 510, where a reproduction mark indicating that the image currently being displayed represents image data to be subjected to reproduction output (printing) is provided. FIGS. 24(a) - 24(c) illustrate examples of display on the display unit 180 in the seventh example. In FIGS. 24(b) and 24(c), a mark "P" shown at a lower right portion of each frame indicates that the corresponding image is an image to be reproduced. Each of FIGS. 24(a) and 24(c) also illustrates an example of a summary. Then, the process proceeds to step 511, where it is determined if a displayed-image changing button has been depressed. If the result of the determination in step 511 is affirmative, the process proceeds to step 512, where the next image data is read from the information recording medium. Then, the process returns to step 502, where image display processing is performed, and the above-described processes are again performed in accordance with the flow. If the result of the determination in step 511 is negative, the process proceeds to step 513, where it is determined if the image-to-be-displayed confirmation end button has been depressed. If the result of the determination in step 513 is affirmative, the operation of confirming the image to be reproduced is terminated, and the process proceeds to step 315. If the result of the determination in step 513 is negative, the process returns to step 511, where it is determined if the displayed-image changing button has been depressed, and the above-described processes are repeated. In step 315, it is determined if an image is to be reproduced. This determination is provided using a switch of the user interface. If the result of the determination in step 315 is affirmative, the process proceeds to step 303, where image reproduction is performed. If the result of the determination in step 315 is negative, the system terminates the operation. Next, a description will be provided of the case of proceeding to step 303 and performing image reproduction. In step 303, the data reading unit 12 reads an AUTOPRINT.MRK file from among files recorded in the information recording medium 11. The contents of the read file are sequentially transferred to the data processing unit 170 to be analyzed. In step 304, the end of the file is confirmed. When the end of the file is not confirmed, the contents of the file are continued to be analyzed, and in step 305, it is determined if TAG" < IMG" is present. If the result of the determination in step 305 is negative, the process returns to step 304, where the analysis of the contents of the file is continued while confirming the end of the file. If the result of the determination in step 305 is affirmative, the process proceeds to step 306, where the name of the image file to be subjected to image reproduction "XXX.JGP" is read from the contents of the file SRC = "XXX.JPG" recorded after the TAG"<IMG". In step 307, image data stored in the image file to be subjected to image reproduction is read based on the read name of the image file to be subjected to image reproduction. In step 308, the image reproduction processing unit 14 executes image reproduction output processing for image reproduction output (printing), to generate image reproduction output data. The generated image reproduction output data is subjected to reproduction output (printing) by the image reproducing unit 13. In the seventh example, JPEG data is used as image data, and the data reproducing unit 13 uses an ink-jet printer as the image reproducing device. Accordingly, the image reproduction processing unit 14 performs processing of obtaining RGB data by decompressing image data stored as JPEG data, color processing, resolution conversion processing, halftoning processing, and the like. When image reproduction output (printing) has been performed, the process returns to step 304, where the system continues the analysis of the contents of the AUTOPRINT.MRK file while confirming the end of the file. Until the end of the file is confirmed, the analysis of the contents is performed by executing the processes of steps 304, 305, 306, 307, 308 and 309. When the end of the file has been confirmed in step 304, the system terminates its operation. As described above, desired image data is automatically selected from the information recording medium where the data is recorded according to the image filing method of the seventh example, and image reproduction output is performed. Accordingly, by executing the image filing method and the image reproducing method, desired image data recorded in the information recording medium can be automatically reproduced and output without assigning the desired image using a memo or the like. Furthermore, since means for confirming an image to be reproduced is provided, it is possible to easily confirm the image to be reproduced by the user's instruction before automatically performing image reproduction. Although in the seventh example, JPEG data is used as image data and image data for display, image data is not limited to JPEG data. For example, data conforming to TIFF, PICT or the like may also be used. RAW data may also be used. In this case, however, it is necessary to record information relating to image reproduction in the information recording medium together with image data. When using data having a format other than the JPEG format, it is only necessary to change processing performed by the image reproduction processing unit 14 and the data processing unit 170 shown in the seventhexample depending on each image data. The method is not limited to a specific type of image data being used. Although in the seventh example, an ink-jet printer is used as the image reproducing device, the device is not limited to such a printer. For example, a sublimation-type thermal printer or a silver-halide-film printer may be used. Although a CRT is used as the data display device, the display device is not limited to such a device. For example, an LCD, a plasma display, an LED display, or any other printer may be used. When using such a device, also, it is only necessary to change processing in the image reproduction processing unit 14 and the data processing unit 170 so as to perform processing corresponding to a printer or a soft copy display device being used. Accordingly, any appropriate image reproducing device and data display device may be used. In the image reproduction system, by analizing recorded data at a corresponding position based on the position and the size of image-reproduction instruction data in a file, and determining how the contents of the data correspond to predetermined contents of recording, it is determined whether or not image data recorded in the file is to be reproduced. Accordingly, it is only necessary that image data and image-reproduction instruction data for instructing whether or not the image data is to be reproduced are recorded in the file. There is no limitation in the position, the size, the contents, the order and the like of recording. Eighth example As methods for confirming an image to be reproduced, a method of displaying a summary of images to be displayed, and a method of individally displaying image data recorded in an information recording medium and displaying, when the concerned image is an image to be displayed, a mark indicating that fact together with the image data have been described in detail. As another method for confirming an image to be reproduced, there is a method of displaying a summary of image data recorded in an information recording medium, and displaying, when the concerned image data represents an image to be reproduced, that fact for each image in the summary. FIG. 24(c) illustrates an eighth example of the above-described method. A summary of image data recorded in the information recording medium is displayed on the display unit. In the eighth example, a thumbnail image is used as the displayed image. A mark "P" is simultaneously displayed at a lower right portion of the thumbnail image when the image is to be displayed. The method of indicating an image to be displayed is not limited to such a method. For example, a method of changing the hue of an image to be reproduced from the hue for other images, or a method of providing a frame for an image to be reproduced may be adopted. Procedures actually executing the eighth example in an image output system and apparatus can be obtained by correcting procedures for executing the above-described two methods. Hence, further description thereof will be omitted. Ninth example A ninth example will now be described. An object of this example is to easily confirm an image to be reproduced in an apparatus for automatically reproducing an image represented by image data recorded in an information recording medium. For that purpose, an image-reproduction instruction data file for specifying image data subjected to image reproduction is provided, and means for grasping the contents of the file before performing image reproduction is provided. By utilizing this function, it is possible to perform warning for an operational error or the like produced in automatic printing when the the number of printable images is smaller than the number of images to be printed. A description will now be provided of such processing according to the ninth example. FIG. 21 is a diagram illustrating an image reproduction system (apparatus) 60 for executing an image reproduction method according to the ninth example. This image reproduction apparatus (system) 60 automatically selects a desired image from among images recorded in an information recording medium 11, and performs reproduction output (printing) of the selected image. At that time, the apparatus 60 checks the number of prints outputtable from the apparatus and the number of images to be automatically output. If the number of images to be output exceeds the number of outputtable prints, the apparatus 60 displays a warning to suspend image output and to prevent occurrence of an output error. For that purpose, the apparatus 60 provides a system-state detection unit 20 in contrast to the apparatuses of the foregoing examples. In the system (apparatus) 60, an ink-jet printer is used as an image reproducing device of an image reproducing unit 13. The number of prints suppliable from the ink-jet printer is given based on the total amount of inks of respective colors to be supplied and the number of printing sheets. Accordingly, in the ninth embodiment, the system-state detection unit 20 includes a device for optically monitoring the capacity of ink tanks of the ink-jet printer, and a device for monitoring the number of sheets from the thickness of the sheets. It is thereby possible to always detect the current number of prints outputtable from the ink-jet printer. This approach may also be applied to a laser-beam printer or other printers. Other components in the ninth example are the same as in the foregoing examples. Next, a description will be provided of the operation of the image reproduction system 60 of the ninth example. FIGS. 22 and 23 illustrate the operational flow of the image reproduction system 60. The operational flow is set in a RAM, a hard disk or the like of the system control unit 15 of the image reproduction system 60. When the image reproduction system 60 has started, for example, by turning on the power supply, the operational flow is read and executed. First, in step 700, it is determined if an information recording medium 11 is set in a data reading unit 12. If the result of the determination in step 700 is affirmative, the process proceeds to step 701, where initial setting is performed, i.e., a value 0 is set in a counter TPCN for setting the total number of prints, and a value 0 is set in a counter PCN for setting the number of prints for each image. The process then proceeds to step 702, where the data reading unit 12 reads an AUTOPRINT.MRK file from among files recorded in the information recording medium 11. The contents of the read file are sequentially transferred to a data processing unit 170 to be analyzed. In step 703, the end of the file is determined. If the result of the determination in step 703 is affirmative, the process proceeds to step 709, where the value of the counter PCN is added to the value of the counter TPCN. The value of the counter TPCN obtained at that time is the total number of image reproduction operations (prints). If the result of the determination in step 703 is negative, the contents of the file are continued to be analyzed, and in step 704, it is determined if TAG"<IMG" is present. If the result of the determination in step 704 is affirmative, the process proceeds to step 707, where the value currently held by the counter PCN is added to the value of the counter TPCN. The process then proceeds to step 708, where the value of the counter PCN is set to 1. The process then returns to step 703, and the analysis of the contents of the file is continued. If the result of the determination in step 704 is negative, the process proceeds to step 705, where it is determined if TAG"CIFF_PRINT_COUNT=" is present in the contents of the file. If the result of the determination in step 705 is negative, the process returns to step 703, and analysis of the contents of the file is continued. If the result of the determination in step 705 is affirmative, a value "X" set in TAG"CIFF_PRINT_COUNT=" in the form of CIFF_PRINT_COUNT="X" is set in the counter PCN. The process then returns to step 703, and the analysis of the contents of the file is continued. Step 710 is executed after step 709. In step 710, the number of prints outputtable from the apparatus (system) is read from the system-state detection unit 20. Then, in step 711, it is determined if the value of the counter TPCN obtained in step 709 is equal to or less than the outputtable prints read in step 710. If the result of the determination in step 711 is negative, the process proceeds to step 724, where warning display is performed on a data display unit 180, and the operation of the system is terminated. If the result of the determination in step 711 is affirmative, the process proceeds to step 712, where image reproduction output (printing) is performed. Next, a description will be provided of the case of proceeding to step 712 and performing image reproduction. In step 712, initial setting is performed, and a value 0 is set in the counter PCN for setting the number of prints for each image. Then, in step 713, the data reading unit 12 reads an AUTOPRINT.MRK file from among files recorded in the information recording medium 11. The contents of the read file are sequentially transferred to the data processing unit 170 to be analyzed. In step 714, the end of the file is confirmed. When the end of the file has been confirmed, the process proceeds to step 722, where it is determined if the value of the counter PCN is 0. If the result of the determination in step 722 is affirmative, the system terminates its operation. If the result of the determination in step 722 is negative, the process proceeds to step 723, where about PCN prints of image data corresponding to the file name recorded in a file-name temporarily storing folder PFN are output, and the operation of the system is terminated. When the end of the file is not confirmed, the contents of the file are continued to be analyzed, and in step 715, it is determined if TAG"<IMG" is present. If the result of the determination in step 715 is negative, the process proceeds to step 716, where it is determined if TAG"CIFF_PRINT_COUNT=" is present. If the result of the determination in step 716 is affirmative, a value "X" given in the form of CIFF_PRINT_COUNT=X is set in the counter PCN. The process then returns to step 714, and the analysis of the contents of the file is continued while confirming the end of the file. If the result of the determination in step 715 is affirmative, the process proceeds to step 718, where it is determined if the value of the counter PCN is 0. If the result of the determination in step 718 is affirmative, the process proceeds to step 720. If the result of the determination in step 718 is negative, the process proceeds to step 719, where about PCN prints of image data corresponding to the file name recorded in the file-name temorarily storing folder PFN are output. The process then proceeds to step 720. In step 720, the file name recorded immediately after TAG"<IMG" is read and is set in the file-name temporarily storing folder PFN. In step 721, a value 1 is set in the counter PCN. The process then returns to step 714, and the analysis of the contents of the file is continued while confirming the end of the file. In the ninth example, JPEG data is used as image data, and the data reproducing unit 13 uses an ink-jet printer as the image reproducing device. Accordingly, the image reproduction processing unit 14 performs processing of obtaining RGB data by decompressing image data stored as JPEG data, color processing, resolution conversion processing, halftoning processing, and the like. As described above, in the image reproduction system of the ninth example, desired image data is automatically selected from the information recording medium where the data is recorded, and image reproduction output is performed. Accordingly, by executing the image filing method and the image reproducing method, desired image data recorded in the information recording medium can be automatically reproduced and output without assigning the desired image using a memo or the like. Furthermore, since means for confirming the total output number of images to be reproduced and the number of prints currently outputtable from the system (apparatus), means for determining if the number of outputtable prints is larger than the total number of output prints, and means for displaying warning in accordance with the result of the determination are provided, the user can easily confirm whether or not an image can be output before automatically performing image reproduction, and it is therefore possible to prevent an output error. Although in the ninth example, JPEG data is used as image data, image data is not limited to JPEG data. For example, data conforming to TIFF, PICT or the like may also be used. RAW data may also be used. In this case, however, it is necessary to record information relating to image reproduction in the information recording medium together with image data. When using data having a format other than the JPEG format, it is only necessary to change processing performed by the image reproduction processing unit 14 shown in the ninth example depending on each image data. The image data is not limited to a specific type. Although in the ninth example, an ink-jet printer is used as the image reproducing device, the device is not limited to such a printer. For example, a sublimation-type thermal printer or a silver-halide-film printer may be used. Alternatively, a soft-copy display device, such as a CRT, an LCD, a plasma display or the like, may be used. When using such a device, also, it is only necessary to change processing in the image reproduction processing unit 14 and the system-state detection unit 20 and monitoring means so as to perform processing corresponding to a printer or a soft copy display device being used. Accordingly, the method may use any appropriate image reproducing device. For example, in the case of a sublimation-type thermal printer, a sublimation dye is provided in the form of a sheet. Since an area necessary for providing a print and the total area of sheets set in advance in the apparatus are known, it is possible to know the number of prints available from now on by storing the number of prints obtained up to the present. As described above, it is desirable to easily confirm an image to be reproduced in an apparatus for automatically reproducing an image represented by image data recorded in an information recording medium. For that purpose, an image-reproduction instruction data file for specifying image data to be subjected to image reproduction, and means for grasping the contents of the file before performing image reproduction are provided. It is thereby possible to easily confirm an image to be reproduced, display a summary of images to be displayed on data display means, add a mark indicating an image to be reproduced to an image displayed on the data display means, compare the number of outputtable prints with the total number of output prints, perform warning display when the number of outputtable prints is insufficient, and thereby prevent an output error. Tenth example A method for editing data recorded in an information recording medium according to a tenthexample will now be described in detail with reference to the drawings. The tenth example has a feature in that an output error when image data corresponding to image-reproduction instruction data is absent in the information recording medium. Means for accessing image data to be reproduced is provided. When image-reproduction instruction data is added to image data to be erased, the image-reproduction instrution data is also erased. When there is no image in the data, a reproduction output operation is skipped. FIG. 25 illustrates a system for executing a method for editing data in an information recording medium in the tenth example. This system provides an instruction whether or not image data recorded in an information recording medium 11 is to be deleted, or whether or not image data is to be reproduced, and edits data in the information recording medium 11, by accessing image data and image-reproduction instruction data recorded in the information recording medium 11. A CF is used as the information recording medium 11. The information recording medium 11 is not limited to the CF. For example, a floppy disk or the like may also be used. The information-recording-medium-data editing system 10 includes an information-recording-medium accessing unit 120 for accessing recorded data, comprising image-reproduction instruction data and image data, recorded in the information recording medium 11, and outputting the recorded data to a bus 16 or recording a result of processing in the system in the information recording medium 11, a system control unit 15 for controlling the operations of the entire system by controllling respective units of the information-recording-medium-data editing system 10, a user interface unit 190, having an information-recording-medium-data display unit for reading data recorded in the information recording medium 11 under the control of the system control unit 15 or according to the user's instruction provided at the user interface unit 190, and displayng image data and image-reproduction instruction data obtained via the bus 16, for obtaining image-exchange instruction information, image-data-erasure instruction information and image-reproduction instruction information provided by the user. The format of the image file shown in FIGS. 17(a) - 17(c) is used as the format of the image file of the tenth example. The contents of recording of 'AUTOPRINT.MRK' shown in FIG. 18 are also used Such a file is generated by image input means, such as a digital camera or the like, a personal computer, the information-recording-medium-data editing system of the tenth example, or the like. FIG. 26 illustrates a display picture surface of the user interface unit 190 of the tenth example. In FIG. 26, reference numeral 41 represents a unit for displaying data of the information recording medium, on which image data and image-reproduction instruction data recorded in the information recording medium 11 are displayed. A mark "P" shown at a lower right portion of the displayed image indicates that this image is to be reproduced. A button 42 is used for exchanging the image. By depressing the button 42, image data recorded immediately before the currently displayed image is displayed in the region 41 in accordance with the sequence of images recorded in the information recording medium 11. A button 43 is also used for exchanging the image. By depressing the button 43, image data recorded immediately after the currently displayed image is displayed in the region 41 in accordance with the sequence of images recorded in the information recording medium 11. A button 44 is used for erasing an image recorded in the information recording medium. By depressing the button 44, image data corresponding to the currently displayed image is erased from the information recording medium 11. A button 45 is used for indicating that the displayed image is to be reproduced (printed). By depressing the button 45, the file name of the currently displayed image data recorded in the information recording medium 11 is read (in the tenth example, this file name is stored in the system control unit 15 as temporarily held data), and is written in an AUTOPRINT.MRK file of the information recording medium 11. When the button 45 is again depressed for image data for which an image-reproduction instruction has already been provided, that operation is neglected. A button 46 is used for instructing that image reproduction (printing) of the displayed image is to be cancelled. By depressing the button 46, the file name of the currently displayed image data recorded in the information recording medium is read (in the tenth example, the file name of the currently displayed image data is held by the system control unit 15 as temprarily held data), and the file name written in the AUTOPRINT.MRK file of the information recording medium 11 is erased. The button 46 is effective only for image data for which an image-reproduction instruction has already been provided. The operation of the button 46 is neglected for other images. Next, a description will be provided of the operation of the information-recording-medium-data editing system 10 of the tenth example. When an instruction to erase image data is provided from the user interface unit 190, whether or not image reproduction is instructed for the image data is retrieved. If image reproduction is instructed, the image-reproduction instruction is released. That is, whether or not the file name is described in the AUTOPRINT.MRK file is retrieved. If the file name is described, the file name is erased from the AUTOPRINT.MRK file. FIG. 27 is a flowchart illustrating the above-described operation of the information-recording-medium-data editing system 10 of the tenth example. The program represented by this operational flow is set in a RAM, a hard disk or the like of the system control unit 15 of the information-recording-medium-data editing system 10. When the information-recording-medium-data editing system 10 has started, for example, by turning on the power supply, the operational flow is read and executed. First, in step 501, it is determined if the erase button has been depressed. This operation actually starts by depressing the erase button. If the result of the determination in step 501 is affirmative, the process proceeds to step 502, where the file name of the currently displayed image data is read, and the contents of the AUTOPRINT.MRK file are analyzed. Then, in step 503, it is determined if the read file name of the displayed image data is present in the AUTOPRINT.MRK file. If the result of the determination in step 503 is affirmative, that file name is deleted from the AUTOPRINT.MRK file, and the file of the displayed image is erased from the information recording medium 11. If the result of the determination in step 503 is negative, the file of the displayed image is erased from the information recording medium 11, because this image is not an image to be displayed and no problem arises during image reproduction output even if the image data is erased. Although in the tenth example, image data recorded in an information recording medium is individually displayed, and it is determined whether or not the image is to be erased, the method is not limited to such an approach. The gist of the above examples is as follows. That is, image data and data instructing whether or not the image data is to be subjected to reproduction output are recorded in an information recording medium. When editing data of the information recording medium, and erasing image data, it is checked whether or not reproduction of the image data is instructed. If reproduction of the image data is instructed, the reproduction instruction data is released. Accordingly, various means may be considered. For example, the method can also be executed when a summary of image data is displayed, and an erasing operation is performed by selecting an image using a mouse or the like, or when a file of an information recording medium is directly edited using a file editor or the like. As described above, means for erasing image-reproduction instruction data relating to image data based on an instruction to erase the image data is provided, and the image-reproduction instruction data for the image data is also erased when erasing the image data. Accordingly, the problem that image data to be reproduced is absent in an image reproducing operation and the image reproducing operation ends with an error is prevented. Preferred embodiment A preferred embodiment of the present invention will now be described. An object of this embodiment is to prevent the problem that, when contradiction arises in image data and image-reproduction instruction data recorded in an information recording medium, an image reproducing operation ends with an error. For that purpose, in the above-described tenth example, means for checking image-reproduction instruction data when erasing image data recorded in an information recording medium, and releasing the image-reproduction instruction data when an image-reproduction instruction is provided for the image data to be erased is provided. In the preferred embodiment, means for executing an image reproducing operation by neglecting image-reproduction instruction data when image data is absent in an information recording medium although the image-reproduction instruction data is provided. Accordingly, even if contradiction arises in image data and image-reproduction instruction data recorded in an information recording medium, for example, even if an actual image is absent although an image-reproduction instruction data is provided, an image reproducing operation is always executed without producing an error. FIG. 28 illustrates an image reproduction system (apparatus) 10 which executes an image reproduction method according to the preferred embodiment. This image reproduction apparatus (system) 10 automatically selects desired image data from among image data recorded in an information recording medium 11, and performs reproduction output (printing) of an image represented by the selected image data. In the embodiment, a CF is used as the information recording medium 11. The information recording medium 11 is not limited to the CF. For example, a floppy disk, a DVD or the like may also be used. The image reproduction system (apparatus) 10 includes a data reading unit 12 for reading recorded data, comprising image-reproduction instruction data and image data, recorded in the information recording medium 11, and outputting the recorded data to a bus 16, a system control unit 15 for controlling the operations of the entire system by controllling respective units of the image reproduction system 10, an image reproduction processing unit 14 for receiving image data read by the data reading unit 12 under the control of the system control unit 15 and output to the bus 16, and converting the image data into reproduction output data for performing reproduction output and outputting the reproduction output data, an image reproducing unit 13 for receiving the reproduction output data to perform reproduction output (printing), a data processing unit 170 for analyzing the contents of image-reproduction instruction data by selectively accessing that data, and a system display unit 180 for displaying the operational state of the system in accordance with the results of the data processing unit 170 and the system control unit 15. The format of the image file of the information recording medium in this embodiment is the same as in the format of the file described in the tenth example, Hence, further desription thereof will be omitted. As described above, by checking the contents of recording of AUTOPRINT.MRK, the file of image data to be subjected to image reproduction can be obtained. Furthermore, by checking the root directory, the name of the file recorded in the information recording medium can be obtained. The contents of the information recording medium are edited using input means of a personal computer, a digital camera or the like. Next, a description will be provided of the operation of the image reproduction system (apparatus) 10 of the embodiment, which is a feature of the present invention. FIG. 29 illustrates the operational flow of the image reproduction system 10 of the embodiment. The program represented by the operational flow is set in a RAM, a hard disk or the like of the system control unit 15 of the image reproduction system 10. When the image reproduction system 10 has started, for example, by turning on the power supply, the operational flow is read and executed. First, in step 701, it is determined if the information recording medium 11 is set in the data reading unit 12. If the result of the determination in step 701 is affirmative, the process proceeds to step 702, where the data reading unit 12 reads an AUTOPRINT.MRK file from among files recorded in the information recording medium 11. The contents of the read file are sequentially transferred to the data processing unit 65 to be analyzed. In step 703, the end of the file is confirmed. When the end of the file is not confirmed, the contents of the file are continued to be analyzed, and in step 704, it is determined if TAG" < IMG" is present. If the result of the determination in step 704 is negative, the process returns to step 703, where the analysis of the contents of the file is continued while confirming the end of the file. If the result of the determination in step 704 is affirmative, the process proceeds to step 705, where the name of the image file to be subjected to image reproduction "XXX.JGP" is read from the contents of the file SRC = "XXX.JPG"> recorded after the TAG"<IMG". In step 706, it is determined if a file corresponding to the read name of the image file to be subjected to image reproduction is present in the information recording medium 11. If the result of the determination in step 706 is affirmative, the process proceeds to step 707, where image data to be reproduced stored in the information recording medium 11 is read. Then, in step 708, the image reproduction processing unit 14 executes image reproduction output processing for image reproduction output (printing) to generate image reproduction output data, which is subjected to reproduction output (printing) by the image reproducing unit 13. If the result of the determination in step 706 is negative, the process proceeds to step 709, where the name of the image file to be subjected to image reproduction is temporarily stored in a storage region. At that time, the image reproduction output operation is skipped, and the operation of the system returns to step 703. In this embodiment, JPEG data is used as image data for display, and the data reproducing unit 180 uses an ink-jet printer as the image reproducing device. Accordingly, the image reproduction processing unit 140 performs processing of obtaining RGB data by decompressing image data stored as JPEG data, color processing, resolution conversion processing, halftoning processing, and the like. When image reproduction output (printing) has been performed, the process returns to step 703, where the system continues the analysis of the contents of the AUTOPRINT.MRK file while confirming the end of the file. Until the end of the file is confirmed, the analysis of the contents of the AUTOPRINT.MRK file is performed by executing the processes of steps 704, 705, 706, 707, 708 and 709. When the end of the file has been confirmed in step 703, the process proceeds to step 71, where the system displays the file name temporarily stored in the storage region on the system display unit 15 as an unknown file, and terminates the operation. As described above, in the image reproduction system of the embodiment, desired image data is automatically selected from the information recording medium where the data is recorded according to the image filing method of the embodiment, and image reproduction output is performed. Accordingly, as described in the embodiment, by executing the image filing method and the image reproducing method of the present invention, desired image data recorded in the information recording medium can be automatically reproduced and output without assigning the desired image using a memo or the like. Furthermore, it is possible to execute an image reproducing operation by neglecting image-reproduction instruction data when image data is absent in an information recording medium although the image-reproduction instruction data is provided. Hence, even if contradiction arises in image data and image-reproduction instruction data recorded in an information recording medium, for example, even if an actual image is absent although an image-reproduction instruction is provided, an image reproducing operation is always executed without producing an error. Although in the embodiment, JPEG data is used as image data and image data for display, image data is not limited to JPEG data. For example, data conforming to TIFF, PICT or the like may also be used. RAW data may also be used. In this case, however, it is necessary to record information relating to image reproduction in the information recording medium together with image data. When using data having a format other than the JPEG format, it is only necessary to change processing performed by the image reproduction processing unit 14 and the data processing unit 170 shown in the embodiment depending on each image data. The present invention is not limited to a specific type of image data being used. Although in the embodiment, an ink-jet printer is used as the image reproducing device, the present invention is not limited to such a printer. For example, a sublimation-type thermal printer or a silver-halide-film printer may be used. Although a CRT is used as the data display device, the embodiment is not limited to such a device. For example, an LCD, a plasma display, an LED display; or any other printer may be used. When using such a device, also, it is only necessary to change processing in the image reproduction processing unit 14 and the data processing unit 170 shown in the embodiment so as to perform processing corresponding to a printer or a soft copy display device being used. Accordingly, the embodiment may use any appropriate image reproducing device and data display device. In the image reproduction system of the embodiment, by analizing recorded data at a corresponding position based on the position and the size of image-reproduction instruction data in a file, and determining how the contents of the data correspond to predetermined contents of recording, it is determined whether or not image data recorded in the file is to be reproduced. Accordingly, it is only necessary that image data and image-reproduction instruction data for instructing whether or not the image data is to be reproduced are recorded in the file. There is no limitation in the position, the size, the contents, the order and the like of recording. An object of the embodiment is to provide a configuration in which, even when corresponding image data is absent in an information recording medium although image-reproduction instruction data is provided, an image reproducing operation can be executed by neglecting the image-reproduction instruction data. Such a configuration is not limited to the configuration of the eleventh embodiment, but any other appropriate configuration may be adopted within the scope of the appended claims. For example, although in the embodiment, an unknown file is displayed at the final stage, this step may be omitted. As described above, by allowing to supply the image reproduction system with an image output control program from an information recording medium or to execute the program by directly accessing the information recording medium, the image reproduction system can control image output by an image output control program corresponding to each recording format even for an information recording medium in which data are recorded in a plurality of different recording formats. Hence, it is possible to easily control image output for all formats. Furthermore, since an image format and an output control program corresponding thereto are provided from the same information recording medium, the system can automatically set an operation corresponding to the image format recorded in the information recording medium. Hence, embodiments of the present invention can easily be executed because it is unnecessary to set an operational program in accordance with an information medium, Example of application When image data recorded in one of the above-described formats is transferred from a digital camera, a personal computer or the like via one of various kinds of interfaces or via an Internet or the like, the situation after reception of the data is equal to the case of setting of a medium, as described in the foregoing embodiment , although some kind of certification is required when an instruction of output is recognized in the apparatus 10, i.e., when, for example, accounting is performed. Accordingly, after the apparatus has recognized 'data reception' including certification or the like, control similar to the control performed in the above-described embodiment is performed depending on the situation. FIG. 30 is a diagram illustrating a system for performing such a control. As in the case of FIG. 25, an information recording medium 11 includes a general-purpose interface. Although detailed description will be omitted, it is possible to determine data reception by determining whether or not data obtained via a network, IrDA (Infrared Date Association) interface, a 1394 interface (described, for example, in Japanese Patent Application No. 09-030541 (1997), a parallel interface, a serial interface or the like is based on the above-described format, for example, by checking the presence of respective regions shown in FIGS. 1(a) - 1(c). If this determination is performed instead of step 300 shown in FIG. 3, and the process then proceeds to step 301 and succeeding steps, this application may be applied to the above-described embodiment.
