   This application is based upon and claims the benefit of priority from prior Japanese Patent Applications No. 2002-346895, filed Nov. 29, 2002; and No. 2003-349458, filed Oct. 8, 2003, the entire contents of both of which are incorporated herein by reference. 
   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a portable wireless communication terminal having a function for transmitting/receiving multimedia data; a picked-up image editing apparatus; and a picked-up image editing method. In particular, the present invention relates to a portable wireless communication terminal and a picked-up image editing apparatus and method having a function for combining and/or processing a downloaded image together with a picked-up image. 
   2. Description of the Related Art 
   In recent years, there has been a portable telephone (a type of portable wireless communication terminal) having a digital camera incorporated therein such that data picked-up by using this incorporated camera can be transmitted to be attached to E-mail and the data can be received and displayed. 
   Further, there exists a portable telephone comprising a function capable of processing picked-up data and capable of freely setting a motion picture, animation, sound (melody) or the like downloaded over a content provider as a call arrival image as is the case with a variety of multimedia data. 
   The thus downloaded data is often inhibited from being duplicated or processed, and information with copyright protection is added to the data in advance. However, a general user has few opportunities of recognizing them. Therefore, when an attempt is made to freely combine and/or process picked-up images, there are many cases in which such combining and/or processing are/is restricted or inhibited. 
   In addition, the image picked-up by the above-described portable telephone with the camera function and another image with copyright obtained by downloading it can be displayed to be combined with each other. However, the thus combined image cannot be transmitted. Therefore, after the combined image has been temporarily held in the portable telephone, when an attempt is made to transmit it via E-mail, the combined image is not displayed, and cannot be transmitted. At this time, the general user cannot understand why the combined image is not displayed and cannot be transmitted. In such a case, there has been a problem that the user has a trouble with operation, and the usability of the portable telephone is very poor. 
   BRIEF SUMMARY OF THE INVENTION 
   It is an object of the present invention to provide a portable wireless communication terminal capable of notifying the fact that multimedia data cannot be transmitted when the multimedia data targeted to be combined includes data downloaded via a network or protected by copyright information and a picked-up image editing apparatus and a picked-up image editing method incorporated in this portable wireless communication terminal. 
   According to an embodiment of the present invention, a portable wireless communication terminal having an acquiring device which acquires multimedia data, a wireless communication function, and a downloading function for downloading multimedia data over a network by using the wireless communication function, the portable wireless communication terminal comprises: 
   a memory which stores the multimedia data acquired by using the acquiring device and the multimedia data downloaded over the network; 
   a combining instruction issuing unit which issues a combining instruction to combine the multimedia data with each other; 
   a combining unit which, when the combining instruction issued by the combing instruction issuing unit is detected, reads out multimedia data to be combined from the memory, and combines the read out data; 
   a storage control unit which, when the multimedia data combined by the combining unit includes downloaded data, stores storage addresses of respective multimedia data stored in the memory so as to be associated with each other, and, when the multimedia data combined by the combining unit does not include downloaded data, stores the combined multimedia data in the memory; 
   a transmission instruction issuing unit which issues a transmission instruction to transmit the combined multimedia data to an outside of the portable communication terminal; 
   a determination unit which, when the multimedia data is read out by the transmission instruction issuing unit, determines whether or not the storage addresses of multimedia data are stored in the memory; and 
   a disabling unit which, when the determining unit determines that the storage addresses of multimedia data are stored in the memory, disables transmission of the combined multimedia data. 
   According to another embodiment of the present invention, a picked-up image editing apparatus comprises:

The portable telephone  1  comprises: a wireless transmitter/receiver  20  for transmitting/receiving and modulating/demodulating a sound or text (E-mail data) via the antenna  11  in a wireless manner; a wireless signal processor  21  for carrying out processing required for wireless communication such as demodulating the sound or text (E-mail data) received by the wireless transmitter/receiver  20 , or modulating a sound or text to be transmitted to the wireless transmitter/receiver  20 ; a controller  22  for controlling a variety of operations and a whole operation; an image compression/encoding processor  23  for compressing/encrypting an image or the like picked-up by an image pickup module  181  (including the object lens  18  and a rewritable flash ROM (not shown)) and a digital sound processor (DSP)  182 ; a flash ROM  24  for storing a variety of programs described later; a driver  25  for driving the display device  13 ; a driver  26  for driving the subsidiary display device  16 ; a subscriber information memory  27  for storing telephone numbers for calling the portable telephone  1  or profile data such as operator (subscriber) ID; a system ROM  28  for storing a variety of programs or the like for controlling the controller  22 ; a RAM  29  for storing a variety of data required for the portable wireless communication terminal, storing data required for the controller  22  to operate, and storing an image file picked-up by a picking-up portion (object lens  18 , image pickup module  181 , DSP  182 ) and compressed/encoded by a program stored in an image processing program region of the ROM  24  or an image file downloaded via WWW (World Wide Web); the image pickup module  181  including CCD or CMOS, for capturing a color image; the DSP  182  for encoding the image captured by the image pickup module  181 ; the broadcast speaker  19 ; a vibrator  191 ; a driver  192  for driving an LED  171 ; and a sound signal processor  200  for carrying out decoding a signal output from the wireless signal processor  21  and driving the speaker  12 , thereby outputting a sound. 
   The image compression/encoding processor  23  is a circuit portion which encodes a still picture in a JPEG scheme or a motion picture in an “amc” scheme compatible with MPEG-4 scheme after capturing the still picture or motion picture picked-up by the picking-up portion (object lens  18 , image pickup module  181 , DSP  182 ) and digitally encoded and a display image (still picture or motion picture) combined when a call arrival image is produced in a camera mode described later. In addition, this portion comprises a function for downloading image data over a network by means of a system (not shown) or decoding a still picture file attached to a received E-mail (JPEG (JPG) scheme, SMP scheme, PNG scheme, GIF scheme) or a motion picture file (MPEG (AMC) ASF) scheme, GIF animation scheme). In the still picture picked-up at the picking-up portion, when the still picture is encoded in the JPEG scheme, a thumbnail image or a control tag such as a picking-up condition is set and is produced as a file based on a DCF standard or an Exif standard. 
     FIG. 3  is a schematic view showing a memory area configuration of the RAM  29 . The RAM  29  is segmented into an area of a data folder management table  290 ; an area of a data folder  291 ; an area of a call arrival setting table  292 ; an area of an address notebook table  293 ; and an area of other data memory  294 . 
   A table configuration of the data folder management table  290  is as shown in  FIG. 4 . Actual real data is stored in the data folder  291 . However, the data folder management table  290  managing them is provided so as to write a file name, a data size, a folder attribute, a folder title, a file attribute, and a copyright flag for each record number, and one record is formed of these elements. 
   The folder attribute is provided for sorting and managing items of data. On a display screen, data stored in a data folder is displayed for each folder. Any files are recorded miscellaneously in order of recording. The folder name indicates the name of folder displayed on the display screen. 
   The file attribute designates the attribute of data itself stored in the data folder. A motion picture indicates data (irrespective of the presence or absence of a sound) encoded/compressed in a file conforming to the AMC scheme compatible with the MPEG scheme and a motion picture file picked-up by the portable telephone  1 . Even when no-sound is provided or only a sound is provided, when encoding is carried out in the MPEG scheme, the encoded data is handled as a same folder “movie.” It is assumed that this attribute includes an animation file conforming to the GIF scheme (refer to record No.  15  of  FIG. 4 ) or a file conforming to the PMD scheme (a sound-attachment animation file specialized for a format of the portable telephone (refer to record No.  14  of  FIG. 4 )). 
   The still picture includes a still picture file conforming to the JPEG (JPG) scheme, the BMP scheme, the PNG scheme, or GIF scheme or a still picture file picked-up by the portable telephone  1 . The sound attribute includes an sound file recorded in the portable telephone  1  (refer to QCP format No.  003 ); a file conforming to the PMD format (a sound-attachment animation file specialized for the format of the portable telephone (when no animation is provided)) (refer to record Nos.  007  and  008  of  FIG. 4 ); and a file conforming to the MMF scheme (a memory file specialized for the format of the portable telephone) (refer to record Nos.  009  to  010  of  FIG. 4 ). 
   The call arrival setting table  292  is a table for setting what type of broadcast (screen display and sound (melody) output) is carried out when a call arrival request signal from the outside to an own telephone has been received. In detail, as shown in  FIG. 5 , record No. of the above-described data folder management table  290  is stored. 
   When a file attribute of data corresponding to the stored record No. is a motion picture, this file is opened upon the receipt of the call arrival request signal, and the corresponding motion picture is displayed at the display device  13 . Then, when this motion picture file includes a sound, the corresponding sound is output. When no-sound is included, a defaulted broadcast buzzer is output. 
   When the file attribute of data corresponding to the stored record No. is a still picture, this file is opened upon the receipt of a call arrival request signal, and the corresponding still picture is displayed at the display device  13 . Then, in the call arrival setting table  292 , when record No. corresponding to this still picture file includes record No, of a file whose file attribute is “sound,” the sound corresponding to that record No. is output. Otherwise, a defaulted broadcast buzzer is output. 
     FIG. 5  is a view showing an example of contents of the call arrival setting table  292 . A transmitter number flag in  FIG. 5  includes the transmitter&#39;s telephone number in a call arrival request signal. When this telephone number is identical to that stored in the address notebook table  293 , when the transmitter number flag is set, broadcasting is carried out based on that call arrival setting. A corresponding address denotes a storage address in the address notebook table  293  described above. 
   An operation according to the present embodiment will be described here. First, a general operation will be described in accordance with the flow charts of  FIGS. 6 and 7 . 
   In  FIG. 6 , the portable telephone  1  provides access to an image data download site over a communication network via the antenna  11 , the wireless transmitter/receiver  20 , and the wireless signal processor  21 , downloads image data, and stores the downloaded image data in an image memory  23 . In addition, the image file picked-up by the picking-up portion (object lens  18 , image pickup module  181 , DSP  182 ) and compressed/encoded by the image compression/encoding processor  23  is stored in the other data memory  294  (image memory) of the RAM  29 . 
   When the user sets the image (still picture or motion picture) picked-up by the portable telephone  1  so as to be displayed upon call arrival, the controller  22  determines whether or not the downloaded image is combined with the picked-up image displayed upon call arrival in step A 01  of  FIG. 6 . When the determination result is negative, association with a sound file played back at the same time when this picked-up image is displayed upon call arrival is instructed in step A 02 , and a storage address of a still picture file and a storage address of the sound file are stored in the call arrival setting table  292  so as to be associated with each other in step S 03 . 
   When the downloaded image is combined with the picked-up image, processing goes to step A 04  in which it is determined whether or not a copyright is attached to the downloaded image to be combined. When the determination result is negative, processing goes to step A 07 , and when the determination result is affirmative, processing goes to step A 05 . 
   In step A 05 , association with the sound file played back at the same time when this picked-up image is displayed upon call arrival is instructed. In step A 06 , the storage address of the still picture file, the storage address and combining position of the image to be combined, and the storage address of the sound file are stored in the call arrival setting table  292  so as to be associated with each other. 
   When processing goes to step A 07 , the downloaded image is combined with the picked-up image, and the combining result is captured. Then, the captured result is stored in the new data folder  291  contained in the RAM  29 . In step A 08 , association with the sound file played back at the same time when this combined image is displayed upon call arrival is instructed. In step A 09 , the storage address of the combining result and the storage address of the sound file are stored in the call arrival setting table  292  so as to be associated with each other. 
   In short, when the image (still picture or motion picture) picked-up by the portable telephone  1  is set on the call arrival setting table  292  so as to be displayed upon call arrival, when a copyright protection flag (illegal copy protection) is set to the image to be combined, record No. of the picked-up image and the corresponding record No. are stored to be associated with each other. When no copyright protection flag (illegal copy protection) is set, the combining result is captured. Then, a file is newly created, and record No. of that file is set on the call arrival setting table  292 . 
     FIG. 7  is a flow chart showing more detailed operating procedures for setting the image (still picture or motion picture) picked-up by the portable telephone  1  so as to be displayed upon call arrival. In step B 01 , it is determined whether or not the downloaded image is combined with the picked-up image to be displayed upon call arrival. When the determination result is negative, it is determined in step B 02  whether or not a sound is attached to the picked-up image to be displayed upon call arrival, i.e., a call arrival image. When the determination result is negative, processing goes to step B 05 , and when the determination result is affirmative, processing goes to step B 03 . 
   In step B 03 , it is determined whether or not the sound attached to the call arrival image is output upon call arrival. When the determination result is negative, processing goes to step B 05 , and when the determination result is affirmative, processing goes to step B 04 . In step B 04 , the storage address of the motion picture file is stored in the call arrival setting table  292  so as to be associated with the storage address of the picked-up image. 
   When processing goes to step B 05 , association of the sound output when the call arrival image is displayed with the sound file is instructed. In step B 06 , the storage address of the motion picture file and the storage address of the sound file are stored in the call arrival setting table  292  so as to be associated with each other. 
   When it is determined in step B 01  that the downloaded image is combined with the picked-up image, processing goes to step B 07  in which it is determined whether or not a copyright is attached to the downloaded image to be combined. When the determination result is negative, processing goes to step B 13 , and when the determination result is affirmative, processing goes to step B 08 . In step B 08 , it is determined whether or not a sound is attached to either of the picked-up image file and the downloaded image file. When the determination result is negative, processing goes to step B 11 , and when the determination result is affirmative, processing goes to step B 09 . 
   In step B 09 , it is determined whether or not the sound attached to any image is output upon call arrival. When the determination result is negative, processing goes to step B 11 , and when the determination result is affirmative, processing goes to step B 10 . In step B 10 , the storage address of the motion picture file and the storage address and combining position of the image to be combined are stored in the call arrival setting table  292  so as to be associated with each other. 
   When processing goes to step B 11 , association of the sound file is instructed, and the storage address of the motion picture file, the storage address and combining position of the image to be combined, and the storage address of the sound file are stored in the call arrival setting table  292  so as to be associated with each other. 
   When processing goes to step B 13 , it is determined whether or not a sound is attached to both of the picked-up image file and the downloaded image file. When the determination result is negative, processing goes to step B 18 , and when the determination result is affirmative, processing goes to step B 14 . In step B 14 , a sound to be played back upon call arrival is instructed to be selected. In step B 15 , the combining result is played back and captured, and the captured combining result is newly stored in the data folder  291 . 
   In step B 16 , it is determined whether or not a sound is output upon call arrival. When the determination result is negative, processing goes to step B 19 , and when the determination result is affirmative, processing goes to step B 17 . In step B 17 , an address of the captured motion picture file (combined image) is stored in the call arrival setting table  292 . 
   When processing goes to step B 18 , it is determined whether or not a sound is attached to either of the picked-up image file and the downloaded image file. When the determination result is affirmative, processing goes to step B 15 , and when the determination result is negative, processing goes to step B 19 . In step B 19 , association with the sound file is instructed. In step B 20 , the address of the captured motion picture file (combined image) and the storage address of the sound file are stored in the call arrival setting table  292  so as to be associated with each other. 
     FIGS. 8 ,  9 ,  10 ,  11 , and  12  are flow charts showing procedures for picking-up an image by actually using a camera function of the portable telephone  1  and producing the image as a display image upon call arrival. 
   When the key input device  14  of the portable telephone  1  is operated to enter the camera mode, the controller  22  causes the display device  13  to display a menu in step S 01 . The user selects whether to pick up a motion picture or to pick up a still picture by operating the input device  14  with referring to this menu display. Thus, the controller  22  determines whether a functional mode selected in step S 02  is a still picture or a motion picture. When the selected functional mode is a still picture, processing goes to step S 03 , and when the selected functional mode is a motion picture, processing goes to step S 48  of  FIG. 11 . 
     FIG. 23A  shows an example of screen displayed at the display device when the user has selected a still picture, wherein the “still picture” is underlined.  FIG. 24A  shows an example of screen when a motion picture has been selected, wherein the “motion picture” is underlined. 
   In step S 03 , an electrical signal obtained by picking-up an object by the image pickup module  181  is imaged by means of the DSP  182 , and the resulting image is through-displayed intact at the main display device  13  through the driver  25 . Then, in step S 04 , it is determined whether or not operation of the shutter key  143  is detected. When the determination result is negative, processing returns to step S 03 , and when the determination result is affirmative, processing goes to step S 05  in which the image output from the DSP  182  is stored to be temporarily captured in the other data memory  294  of the RAM  29 . 
   In step S 06 , after a file name input instruction has been displayed for the user at the display device  13 , it is determined whether or not a file name input determination has been detected in step S 07 . When the determination result is affirmative, processing goes to step S 09 , and when the determination result is negative, processing goes to step S 08  in which it is determined whether or not cancellation has been detected. When the determination result is negative, processing returns to step S 06 , and when the determination result is affirmative, processing returns to step S 03 . 
   In step S 09 , a file attribute and/or a still picture, and folder attribute  002  (my photo) are attached to the captured still picture, and stored in the data folder  291 . Then, in step S 10 , the display device  13  displays an image which causes the user to select whether or not this picked-up image is used for a call arrival image.  FIG. 23B  shows an example of display image when the user has selected that the image is used for the call arrival image, wherein “YES” is underlined. 
   Upon the receipt of the above operation, in step S 11 , it is determined whether or not the user has selected that the image is used for the call arrival image. When the determination result is negative, a file name (fuukei.jpg) is set in the picked-up still picture file. Then, the set file name is stored in the data folder  291  of the RAM  29  with record No.  20 , and processing returns to the menu display. When the determination result is affirmative, processing goes to step S 12 . 
   When a user has selected that a picked-up image is produced as a call arrival image, the user selects whether or not a downloaded image is combined with this call arrival image. Upon the receipt of this user selection, the controller  22  determines whether or not the downloaded image is combined with the picked-up image displayed upon call arrival in step S 12 . As a result, when the determination result is negative, processing goes to step S 24 , and when the determination result is affirmative, processing goes to step S 13  in which it is determined whether a still picture or a motion picture is to be combined. When the determination result is the still picture, processing goes to step S 14 , and when the determination result is the motion picture, processing goes to step S 31  shown in  FIG. 10 . 
   In step S 14 , the file attribute and/or still picture files which have/has already been downloaded over a network are displayed at the display device  13  for each folder. In step S 15 , the display device displays a combined image as shown in  FIG. 23C , for example, according to the subsequent user selecting and/or combining operation. 
   Image combining are carried out until a determination of the completion of producing a combined image has been detected. When the completion of producing the combined image is determined, it is determined in step S 17  whether or not a copyright flag is attached to the downloaded image used to be combined. When the determination result is negative, processing goes to step S 21 , and when the determination result is affirmative, processing goes to step S 18 . 
   In step S 18 , the display device  13  displays an indication for checking whether or not a valid copyright flag is attached to the downloaded image. In step S 19 , processing from step S 14  to step S 18  is repeated until YES has been detected for check. When YES is detected, processing goes to step S 20  in which association data is stored in the call arrival setting table  292 , and then, processing goes to step S 24  shown in  FIG. 9 . 
     FIG. 14  shows an example of contents of the call arrival setting table  292  in step S 20 . The figure shows a case in which a still picture file of stamp02.png of record No.  17  has been combined with a still picture file of record No.  20 . 
   A display example of this case will be described with reference to  FIG. 23C . Even with such a combined image, the still picture of stamp 02 .png (still picture indicating a human being on the top left of the display screen in  FIG. 23C ) cannot be newly produced as a combined image because the copyright flag is set. Therefore, the storage contents of the call arrival setting table  292  are produced as record No. of picked-up image file+record No. of combined image file (combining position (upper left corner reference) X coordinate, combining position (upper left corner reference) y coordinate). 
   When processing goes to step S 21 , the combined still picture is played back once. In step S 22 , a file name of this combined image is input and determined. Then, record No.  21  is newly stored in the data folder  291  as shown in  FIG. 15 . Then, in step S 23 , a storage address of this combined image is stored in the call arrival setting table  292 , as shown in  FIG. 16 , and processing goes to step S 24 . 
   An example of contents of the data folder  291  in  FIG. 15  shows a case in which a captured image (chakufuukei.jpg) of the combining result has been newly stored when a copyright protection flag (illegal copy protection) is not set in the combined image file. 
     FIG. 16  shows an example of storage contents of the call arrival setting table  292  when a still picture file of stamp 01 .png of record No.  16  has been combined with a still picture file of record No.  20 , for example, as the above-described combined image. An example of the display screen of the display device  13  will be described again with reference to  FIG. 23C . The still picture of stamp01.png (still picture indicating a human being at the upper left of the display screen in  FIG. 23C ) is newly produced as a combined image because the copyright flag is not set. Therefore, the storage contents of the call arrival setting table  292  are produced as record No. of the newly produced image file. 
   In step S 24 , when a sound is added to a call arrival image, the file attribute and/or sound which have/has been already downloaded over a network, or a file attribute animation (excluding no-sound) file are displayed for each folder. Then, the fact that the user has selected this file is displayed until the selection has been detected in step S 25 . Thereafter, when the user selection is detected, association data as shown in  FIG. 17  is stored in the call arrival setting table  292  in step S 26 . Then, processing returns to the menu display screen. 
   An example of  FIG. 17 , for example, shows storage contents of the call arrival setting table  292  when the still picture file of stamp02.png of record No.  17  is combined with the still picture file of record No.  20 , and record No.  08  is stored as a sound file to be output upon call arrival. The storage contents of the call arrival setting table  292  are produced as record No. of picked-up image file+record No. of combined image file (combining position (upper left corner reference) X coordinate, combining position (upper left corner reference) y coordinate)+record No. of associated sound file. 
   In step S 25  in which “No” is detected, an example of contents of the call arrival setting table  292  in step S 26  is as shown in  FIG. 18 . In  FIG. 18 , there is shown an example of storage contents of the call arrival setting table  292  when record No.  08  is stored in record No.  21  (in a newly produce combined image file) as a sound file to be output upon call arrival. The storage contents of the call arrival setting table  292  are produced as record No. of newly produced image file+record No. of associated sound file. 
   When processing goes to step S 31  shown in  FIG. 10 , the display device  13  displays files whose downloaded file attribute is a motion picture for each folder. In step S 32 , the display device  13  displays a combined image according to the subsequent user selecting and/or combining operation. 
     FIG. 19  shows a storage example of a combined image when a motion picture has been produced to be combined with a still picture in step S 32 . The figure shows a state in which the image file (chakufuukei.gif) produced when the file attribute motion picture (movieframe  01  gif) shown in  FIG. 13  is combined is captured, and is stored as record No.  021  in the data folder  291  of the RAM  29 . 
   That is, even when the picked-up image is a still picture, when a motion picture (animation) is targeted to be combined, the combining result is newly produced as a motion picture in a file. A description will be given by way of example with reference to  FIGS. 23D and 23E . Data for which columns star-marked are changed alternately in  FIGS. 23D and 23E  is produced as a file called movieframe 01 .gif of record No.  18  in  FIG. 19 . 
   Namely, even when the picked-up image is a still picture (an airplane icon in the figure), when the combined image includes a motion picture (columns star-marked in the figures), a motion picture file is produced in accordance with that file format. At this time, a folder attribute, a file attribute and the like are not set. In step S 46  described later, when a sound file (without a copyright) is associated, a sound-attachment animation file (chakufuukei.pmd) is processed as a file. Then, the processed file is stored in the data folder  291 , as shown in  FIG. 20 . 
   Image combining is carried out until a determination of the completion of producing a combined image has been detected. When the completion of producing the combined image is determined, it is determined whether or not the copyright flag is attached to the downloaded image used to be combined in step S 34 . When the determination result is negative, processing goes to step S 38 , and when the determination result is affirmative, processing goes to step S 35 . 
   In step S 35 , the display device  13  displays an indication for checking whether or not a valid copyright flag is attached to the downloaded image. In step S 36 , processing from step S 31  to step S 35  is repeated until affirmative answer YES has been detected. When YES is detected, processing goes to step S 37  in which association data is stored in the call arrival setting table  292 , and then, processing goes to step S 41 . 
   When processing goes to step S 38 , the combined motion picture is played back from start to end timings and is compressed by means of the image compression/encoding processor  23 . Then, in step S 39 , a file name of this combined image is input and determined. Then, in step S 40 , the file name is newly stored in the data folder  291 , and processing goes to step S 41 . 
   In step S 41 , when a sound is added to a call arrival image, the display device  13  displays a file attribute and/or a sound which have/has been already downloaded over a network, or a file attribute animation (excluding no-sound) file for each folder. Then, the display is continued until it is detected in step S 42  that the user has selected the file. When the user selection is detected, it is determined in step S 43  whether or not the copyright flag is attached to the downloaded image used to be combined. When the determination result is negative, processing goes to step S 46 , and when the determination result is affirmative, processing goes to step S 44 . 
   In step S 44 , the display device  13  displays an indication for checking whether or not a valid copyright flag is attached to the downloaded image. In step S 45 , processing from step S 41  to step S 44  is repeated until affirmative answer YES has been detected. When YES is selected, processing goes to step S 47  in which association data is stored in the call arrival setting table  292 , and then, processing returns to the menu display screen. 
   When no copyright flag is attached to the downloaded image, processing goes to step S 46  in which a motion picture is set as a file attribute, and  001  or  004  is set in a folder attribute. Thereafter, processing goes to step S 47  in which association data is stored in the call arrival setting table  292 , and then, processing returns to the menu display screen. 
   When the image pick-up mode selected in step S 02  of  FIG. 8  is a motion picture, processing goes to step S 48  of  FIG. 11  in which an electrical signal obtained by picking-up an object by the image pickup module  181  is imaged by means of the DSP  182 , and the resulting image is through-displayed intact at the display device  13  through the driver  25 . Then, in step S 49 , it is determined whether or not operation of the shutter key  143  is detected. When the determination result is negative, processing returns to step S 48 , and when the determination result is affirmative, processing goes to step S 50  in which the motion picture output from the DSP  182  is stored to be temporarily captured in the other data memory  294  of the RAM  29 . 
   In step S 51 , it is determined whether or not operation of the shutter key  143  is detected. When the determination result is negative, it is determined whether or not a predetermined time interval has elapsed in step S 52 . When the determination result is negative, processing returns to step S 50 , and when the determination result is affirmative, processing goes to step S 53 . When operation of the shutter key  143  is detected, processing goes to step S 53  immediately. 
   When operation of the shutter key  143  is detected in step S 51 , processing goes to step S 53  in which the temporarily captured image is compressed/encoded by means of the image compression/encoding processor  23 . Then, in step S 54 , the display device  13  displays a file name input instruction for the user. 
   In step S 55 , it is determined whether or not a determination of file name input has been detected. When the determination result is negative, processing goes to step S 56  in which it is determined whether or not cancellation has been detected. When no cancellation has been detected, processing returns to step S 54 , and when cancellation has been detected, processing returns to step S 48 . 
   When a determination of file name input has been detected in step S 55 , processing goes to step S 57  in which the compressed/encoded motion picture is stored as shown in  FIG. 21  in the data folder  291  of the RAM  29  by attaching the file attribute and/or motion picture or folder attribute  003  (movie) to the motion picture. 
     FIG. 21  shows an example in which, after a motion picture has been picked-up in the camera mode, when a motion picture file is produced, a file name (car.amc) is set for that motion picture file, and the set file name is stored as record No.  20  in the data folder  291 . 
   In step S 58 , the display device  13  displays an image which causes the user to select whether this picked-up image is used for a call arrival image. In response to this, in step S 59 , it is determined whether or not the user has selected that the picked-up image is used for the call arrival image. When the determination result is negative, processing returns to the display menu, and when the determination result is affirmative, processing goes to step S 60 . 
     FIG. 24B  shows an example of screen of the display device  13  when the user has selected that the picked-up image is used for the call arrival image, wherein “YES” is underlined. In addition, at this time, when the user has selected that the picked-up image is produced as the call arrival image, the user selects whether or not the selected image is combined with a downloaded image. 
   The controller  22  determines whether or not the downloaded image is combined with a picked-up image to be displayed upon call arrival. When the determination result is negative, processing goes to step S 71  shown in  FIG. 12 . When the determination result is affirmative, processing goes to step S 61  in which the display device  13  displays the file attribute, still picture, motion picture, or animation file which has already been downloaded over a network for each folder. In step S 62 , the display device  13  displays a combined image according to the subsequent user selecting and/or combining operation. 
   In step S 63 , processing of step S 62  is repeated until a determination of a combined image has been selected. When the combined image is determined, it is determined in step S 64  whether or not a copyright flag is attached to the downloaded image used to be combined. When the determination result is negative, processing goes to step S 68 , and when the determination result is affirmative, processing goes to step S 65 . 
   In step S 65 , the display device  13  displays an indication for checking whether a valid copyright flag is attached to the downloaded image. In step S 66 , processing from step S 61  to step S 66  is repeated until affirmative answer YES has been detected. When YES is detected, processing goes to step S 67  in which association data is stored in the call arrival setting table  292 , and then, processing goes to step S 71  of  FIG. 12 . 
   When processing goes to step S 68 , the combined still picture is played back from start to end timings and is compressed by means of the image compression/encoding processor  23 . In step S 69 , a file name of this combined image is input and determined, and then, the determined image is newly stored as shown in  FIG. 22  in the data folder  291  of the RAM  29 . Further, in step S 70 , this storage address is stored in the call arrival setting table  292 , and then, processing goes to step S 71  of  FIG. 12   
     FIG. 22  is a view showing an example in which, when a copyright protection flag (illegal copy protection) is not set for an image file having a motion picture combined with a still picture therein, a captured image (chakucar.amc) of the combining result is newly stored in the data folder  291 . 
     FIGS. 25A ,  25 B, and  25 C each show an example of screen on which a motion picture is combined with a still picture. In  FIGS. 25A ,  25 B, and  25 C, data for which star-marked columns are changed alternately is produced as a file called movieframe 01 .gif of record No.  18  in  FIG. 22 . In this case, a motion picture file is produced in accordance with the file format of a picked-up image. 
   In step S 71  of  FIG. 12 , when a sound is added to a call arrival image, the file attribute and/or sound which have/has downloaded over a network, or a file attribute animation (excluding no-sound) file is displayed for each folder. Then, the display continues until the user selection has been detected in step S 72 . 
   When the user selection is detected, it is determined whether or not the copyright flag is attached to the downloaded image used to be combined in step S 73 . When the determination result is negative, processing goes to step S 77 , and when the determination result is affirmative, processing goes to step S 74 . 
   In step S 74 , the display device  13  displays an indication for checking whether or not a valid copyright flag is attached to the downloaded image. In step S 75 , processing from step S 71  to step S 74  is repeated until affirmative answer YES has been detected. When YES is detected, processing goes to step S 76  in which association data is stored in the call arrival setting table  292 , and then, processing goes to the menu display screen. 
   When no copyright flag is attached to the downloaded image at step S 73 , processing goes to step S 77  in which a motion picture is set as a file attribute;  001  or  004  is set as a folder attribute; association data is stored in the call arrival setting table  292 ; and then, processing returns to the menu display screen. 
   When the user uses an image which has been combined and stored once (for example, when the user transmits the image via E-mail), the controller  22  makes a search for the RAM  29 . When the image to be used is stored as association data in the call arrival setting table  292 , it is determined that a copyright is attached to a portion of the combined image. Then, the display device  13  displays an indication that “the image to be used cannot be displayed because a portion of the combined image has a copyright.” In addition, when the combined image is used for transmission via E-mail, the display device displays an indication that “the image cannot be displayed and transmitted because a portion of the combined image has a copyright.” 
     FIG. 26  is a flow chart showing procedures of the controller  22  when the above described combined image is used. 
   In step D 01 , when a combined image is called, processing goes to step D 02  in which a search is made for the call arrival setting table  292  of the RAM  29 . Then, it is determined whether or not the storage addresses of picked-up image and downloaded image configuring a combined image targeted for the call request are stored differently to be associated with each other. 
   In step D 03 , based on the above described search, it is determined whether or not the storage addresses of the picked-up image and downloaded image are different from each other. When the determination result is negative, processing goes to step DOS in which the combined image data is read out from the data folder  291  of the RAM  29  which is a storage destination, and the readout data is displayed. 
   When the storage addresses of the picked-up image and downloaded image are different from each other, processing goes to step D 04  in which the display device  13  displays a message that “the image cannot be displayed because a portion of the combined image has a copyright,” and terminates processing. 
   According to the present embodiment, when the user uses a combined image which has been combined and stored once, when a portion of the combined image has a copyright, the display device displays an indication that “the image cannot be displayed because a portion of the combined image has a copyright.” In addition, when the combined image is used for transmission via E-mail, the display device further displays an additional indication that “transmission is impossible.” Thus, the user can know immediately why the image is not displayed and why transmission via E-mail is impossible. Therefore, operability of the portable telephone  1  can be improved. 
   Now, other embodiments of the present invention will be described here. In the following embodiments, like constituent elements corresponding to the first embodiment are designated by the same reference numerals. A detailed description is omitted here. 
     FIG. 27  is a flow chart showing processing for generating a sound to be output together with a call arrival image when a motion picture according to a second embodiment of the present invention is produced as a call arrival image. Hereinafter, with respect to each element having an identical configuration, a description of the configuration and operation thereof is omitted. A main portion of that operation will be described here. 
   In step C 01 , it is determined whether or not a sound is attached to a motion picture to be combined. When the determination result is affirmative, processing goes to step C 02 , and when the determination result is negative, processing goes to step C 04 . In the former case, in step C 02 , it is determined whether or nor a sound is output upon call arrival. When no-sound is output upon call arrival, processing goes to step C 04 . When a sound is output upon call arrival, processing goes to step S 03  in which a storage address of a motion picture file is stored in the call arrival setting table  292  of the RAM  29 . 
   When processing goes to step C 04 , association with a sound file is instructed here. In step C 05 , it is determined whether or not a copyright flag is attached to this sound file. When the determination result is affirmative, the storage address of the motion picture file and the storage address of the sound file are stored in the call arrival setting table  292  so as to be associated with each other. 
   When no copyright flag is attached to the sound file, processing goes to step C 07  in which a motion picture file is played back and captured while the associated sound file is output. In step C 08 , a motion picture file is newly stored in the data folder  292 . In step C 09 , the storage address of the newly produced motion picture file is stored in the call arrival setting table  292 . 
   When the user outputs a sound when a call arrival motion picture is displayed, i.e., when a sound is output when a combined image is displayed, and a copyright flag is attached to that image, the motion picture file and sound file are stored respectively. The respective storage addresses are stored as association data in the call arrival setting table  292 . Thus, when these addresses are detected, it is determined that a sound output together with the combined image has a copyright. 
   According to the present embodiment, when a combined image with a sound output is transmitted via E-mail and the sound has a copyright, the display device displays an indication that “no transmission is possible because a sound has a copyright.” In this manner, the user can know immediately why transmission is impossible, and operation of the portable telephone  1  can be improved. 
   In the above-described first embodiment and second embodiment, it is determined whether capturing and storage of the combined image enabled or disabled according to whether or not a file (multimedia data) which is a combining source has a copyright. The determination as to whether combining is enabled or disabled may be made on the presumption that “copyright protection is applied to file data downloaded over the Internet in principle.” 
     FIG. 28  is a schematic view showing a memory area configuration of the RAM  29  in the portable telephone  1  which is made compatible with the above-described case. A difference from the above first embodiment and second embodiment is that a data folder management table  295  is provided instead of the data folder management table  290 . The other circuit configuration and memory configuration are identical to those in the above described first and second embodiments. 
   A table configuration of the data folder management table  295  is as shown in  FIG. 29 . Actual real data is stored in the data folder  291 . The data folder management table  290  managing them is provided to write a file name, a data size, a folder attribute, a folder title, and a file attribute on a record No. by record No. basis, and one record is formed of these elements. 
   A region of the folder title is set so as to sort a downloaded item and a produced one in the portable telephone  1  when multimedia files are stored to be mixed. That is, in the folder title, a folder called “my . . . ” stores a variety of data obtained by operating the portable telephone  1  such as startup of a camera function. On the other hand, a folder which is not called “my . . . ” is stored in a folder for storing downloaded data. 
   In the course of combining processing, when data (file) being a combining source is read out from a folder in which “my . . . ” is not set, the corresponding storage addresses are stored respectively without capturing a forcibly composed image. 
   By doing this, the determination as to whether combining is enabled or disabled can be made irrespective of the presence or absence of copyright information. 
   Apart from determination as to whether combining is enabled or disabled on the presumption that “copyright protection is applied, in principle, to file data downloaded over the Internet, for example,” even in a still picture file conforming to the JPEG scheme, the still picture file being picked-up by the portable telephone  1 , the determination as to whether combining is enabled or disabled may be made on the presumption that “all files may be processed as long as they are in a file format conforming to the DFC standard or Exif standard.” 
     FIG. 30  shows a table configuration of the data folder management table  295  of the RAM  29  in the portable telephone  1  which is made compatible with the above described case. Actual real data is stored in the data folder  291 . The data folder management table  290  managing them is provided so as to write a file name, a data size, a folder attribute, a folder title, and, a file attribute in a DCF/Exif flag area on a record No. by record No. basis. One record is formed of these elements. 
   The DCF/Exif flag area is provided as a flag set for sorting the downloaded item and the item produced in the portable telephone  1  according to whether they are produced in accordance with the DCF standard or Exif standard in storing a still picture file conforming to the JPEG scheme. That is, in  FIG. 30 , a file name “taro.jpg” managed in record No.  002  is picked-up by the portable telephone  1 , and is stored in a folder whose folder title is “my photo.” Therefore, this file is found to be a still picture file stored after picked-up, and thus, “1” is set in the DCF/Exif flag area. On the other hand, a file name idol01.jpg managed in record No.  012  is stored in a folder whose folder title is “graphic.” Therefore, this file is found to have been downloaded, and thus, “0” is set in the DCF/Exif flag area. 
   By doing this, the determination as to whether combining is enabled or disabled can be made irrespective of the presence or absence of copyright information. 
   The above-described operations according to the embodiments can be carried out by programming them and causing a computer to execute them. At this time, a computer program can be supplied to a computer through a disk type recording medium such as a floppy disk or a hard disk; a variety of memories such as a semiconductor memory or a card type memory; or a variety of program recording mediums such as a communication network. 
   According to the above mentioned embodiments, when combining of multimedia data is instructed, it is determined whether or not the multimedia data targeted to be combined includes data downloaded via the network by the wireless communication function. When the determination result is affirmative, a corresponding storage address is stored, and transmission of the combined multimedia data is inhibited. Hence, when the multimedia data targeted to be combined includes data downloaded via the network or protected by copyright information, it is possible to notify to the user that transmission cannot be carried out, so that the user&#39;s usability can be improved. 
   It is possible to determine whether combining is enabled or disabled according to the presence or absence of copyright information. 
   The multimedia data combined as the content of call arrival notification can be used, and thus, the multimedia data according to the user&#39;s preference can be freely used without worrying about acquisition by use of a device incorporated in advance or acquisition by downloading. 
   Since the still picture data or the motion picture data is handled as one item of the multimedia data, the user can use the still picture data or the motion picture data without worrying about acquisition by picking-up or downloading. 
   It is possible to determine whether combining is enabled or disabled according to the presence or absence of the still picture data picked-up by the user. 
   When the motion picture data picked-up by the user is targeted to be combined, the multimedia data after combined is uniquely handled as motion picture data, so that the user can use motion picture data freely. 
   Since the sound data recorded by the user is handled as one item of the multimedia data, the multimedia data according to the user&#39;s preference can be freely used. 
   When the multimedia data targeted to be combined includes data downloaded via a network or protected by copyright information, it is possible to check only the combining result without combining and/or storing these items of the data, so that the user&#39;s usability can be improved. 
   In the case of the multimedia data which is not inhibited from being processed, the combining result is stored as new multimedia data, and thus, the user&#39;s usability can be improved. 
   Since the presence or absence of the flag information is used as a criterion as to whether combining of the multimedia data is enabled or disabled, the determination as to whether the combining is enabled or disabled can be easily made without making a determination based on redundant data. 
   Since the presence or absence of the copyright information is used as a criterion as to whether combining of the multimedia data is enabled or disabled, the determination as to whether the combining is enabled or disabled can be easily made.
