## Title
Image recording system and method for controlling the image recording system

## Abstract

A CPU detects the available space A of a first recording medium, the available space B of a second recording medium and a preprogrammed image information amount C necessary for preprogrammed recording by first and second recording medium space managing portions and the contents of preprogrammed recording input from an operation portion by the user. When the preprogrammed image information amount C is larger than the available space A of the first recording medium, an amount of shortage in recording space for preprogrammed information D is obtained from the CPU by subtracting the available space A of the first recording medium from the preprogrammed image information amount C. A larger amount of image information than the recording space shortage D is selected from the image information stored on the first recording medium, and the selected image information is moved to the second recording medium.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an image recording system having a function of receiving image information and a function of performing preprogrammed recording of the received image information onto a plurality of recording media, and a method for controlling the image recording system.
2. Description of the Related Art
Recently, in the broadcasting industry, a shift toward digital broadcasting has been accelerated, and high quality images and high quality sounds are aimed. For these reasons, the amount of image information in broadcasting reaches approximately several tens of Mbps in information rate. As specifications required of an apparatus capable of recording this image, it is necessary that the information recording rate be higher than the broadcast information rate and the apparatus have a recording capacity of approximately several tens of GB (gigabyte) to realize recording for a considerable period of time. Examples of recording apparatuses capable of meeting these requirements include magnetic tape recording apparatuses, magnetic disk recording apparatuses (hard disk apparatuses) and optical disk recording apparatuses. Of these, magnetic tape recording apparatuses are poor in information accessing capability, and therefore, hard disk apparatuses and optical disk apparatuses are attracting attention as the next recording apparatuses. Particularly, hard disk apparatuses that have a sufficiently high recording rate and can have a sufficiently large recording capacity are sufficiently ready for recording of the above-mentioned high-quality broadcasts. Moreover, optical disk apparatuses capable of recording on exchangeable media although inferior to hard disk apparatuses in both recording rate and capacity are regarded as optimum as image storing apparatuses.
When these circumstances are considered, for example, a usage is considered such that a hard disk apparatus is used as a general-purpose image recording apparatus and when the user wants to store some of the recorded images, the images are stored on a medium by an optical disk apparatus. It is to be noted that another hard disk apparatus or a magnetic tape recording apparatus may be used as the means for storing images. Moreover, these apparatuses all have a preprogrammed recording function, and by enabling a target image to be recorded even during the user's absence by preprogramming the apparatus to record the target image, the image can be reproduced and viewed at the user's convenience. Thus, the preprogrammed recording function is one of the functions essential to these recording apparatuses.
When a larger amount of image information than the available space of the recording medium set in the image recording apparatus is recorded, the following occur:
(1) The user does not notice that the available space of the recording medium is smaller than the amount of the image information to be recorded, and the image information is interrupted when all the available space is used.
(2) The user takes out the recording medium with a small available space, and sets another recording medium with a sufficient available space in the apparatus. As means for solving these problems, the following technologies are proposed:
A multi-volume continuous recording apparatus disclosed in Japanese Unexamined Patent Publication JP-A 6-251562 (1994) has a buffer temporarily storing signals recorded on the recording medium, and by stopping the output of the buffer when the available space of the recording medium becomes small, resuming the output of the buffer after a different recording medium is set and performing recording, a long-time image can be recorded without the information interrupted when the recording medium is changed.
According to the information storage control method disclosed in Japanese Unexamined Patent Publication JP-A 10-172237 (1998), by stopping writing of data onto an external storage medium when it is determined that the data is not stored on the external storage medium and storing the data in internal storage means, the data scheduled to be stored can be stored without interrupted.
In a network recording control apparatus disclosed in Japanese Unexamined Patent Publication JP-A 11-176082 (1999), a data transmitter detects the remaining space of the recording medium of a data receiver forming a network, and by changing the receiver in the middle of data transmission when long-time image data is transmitted, data can be continuously recorded on a plurality of receivers.
As described above, image information larger than the available space of a recording medium is enabled to be recorded without interrupted by continuously recording the information on another recording medium or apparatus. This operation is performed by user himself or by an apparatus.
As described above, when a larger amount of image information than the available space of the recording medium set in the recording apparatus is recorded, the image can be recorded only to the middle or changing the recording medium places a load on the user. In the technologies disclosed in the patent applications, since one piece of image information is recorded being divided on two or more media, the management of recording media with respect to image information is complicated, and to seamlessly reproduce an image without any interruption at the points of division and without the same part of the image repeated, a recording and reproduction processing of the joints of the points of division of the information is required. This complicates the system and increases the price.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Now referring to the drawings, preferred embodiments of the invention are described below.
Hereinafter, embodiments of the invention will be described. FIG. 1 is a block diagram showing the structure of an image recording system 14 according to an embodiment of the invention. The image recording system 14 comprises an image receiving portion 1, a control portion 2, an operation portion 3, a first recording apparatus 4, a second recording apparatus 6, a display portion 8 and an output portion 9. The image receiving portion 1 is means for receiving external image information from a broadcasting station or the like and inputting the received information. The operation portion 3 is a portion where the user inputs an operation instruction of the image recording system 14 from the outside. The operation portion 3 is provided with non-illustrated switches and buttons and is also used for inputting the contents of programming when preprogrammed recording of an image is performed. A first recording medium 4a for image recording is incorporated in and controlled by the first recording apparatus 4. The amount of image information recorded on the first recording medium 4a and the available space of the first recording medium 4a are managed by a first recording medium space managing portion 5. Likewise, a second recording medium 6a for image storage is incorporated in and controlled by the second recording apparatus 6. The available space of the second recording medium 6a is managed by a second recording medium space managing portion 7. The first and the second recording apparatuses 4 and 6 also have a reproduction function, and reproduce the image information recorded on the recording media 4a and 6a so that the user can view the image through the output portion 9. The display portion 8 provides various kinds of displays for notifying the user of the operation condition of the image recording system 14 and the contents input by the user.
The control portion 2 comprises a CPU 13 and non-illustrated parts such as a ROM (read-only memory) for an apparatus control program and a RAM (random-access memory) for storing control data, and collectively manages and controls all the operations associated with the image managing system 14. The control portion 2 has a preprogrammed image information amount storage portion 10, a first recording medium available space storage portion 11, a second recording medium available space storage portion 12, a recording space shortage storage portion 18 and a first recording medium image information amount storage portion 19. Connected to the control portion 2 are the image receiving portion 1, the operation portion 3, the first and the second recording apparatuses 4 and 6, and the display portion 8. The image receiving portion 1 is connected to the first recording apparatus 4. The first recording apparatus 4 is connected to the second recording apparatus 6. The output portion 9 is connected to the first recording apparatus 4 and to the second recording apparatus 6.
FIG. 2 is a flowchart of an image recording processing performed by the image recording system 14 of the embodiment. First, at step S1, the power of the apparatus is turned on. At step S2, the available space A of the first recording medium 4a at this point of time is stored in the first recording medium available space storage portion 11 by the first recording medium space managing portion 5. At step S3, the available space B of the second recording medium 6a at this point of time is stored in the second recording medium available space storage portion 12 by the second recording medium space managing portion 7.
At step S4, the user operates the operation portion 3 to input the contents of recording of the image to be recorded. Examples of the input contents include the date of recording, the start time of recording, the end time of recording, the channel to be recorded and the recording mode. The recording mode is a selection between high-quality and large-capacity recording and low-quality and small-capacity recording. Making this selection determines the rate of image information recording onto the recording medium. Since the recording rate and the recording time can be recognized from the input contents, at step S5, the recording capacity required to perform the preprogrammed recording is calculated by the CPU 13. That is, the preprogrammed image information amount C is calculated, and the value is stored in the preprogrammed image information amount storage portion 10.
Then, at step S6, the CPU 13 compares the preprogrammed image information amount C stored in the preprogrammed image information amount storage portion 10 with the available space A of the first recording medium 4a stored in the first recording medium available space storage portion 11 to determine whether or not the available space A of the first recording medium 4a is equal to or larger than the preprogrammed image information amount C. When the available space A of the first recording medium 4a is larger or equal, at step S7, the apparatus is brought into a recording standby state, and when the recording time comes, the image is recorded onto the first recording medium 4a. When the available space A of the first recording medium 4a is smaller than the preprogrammed image information amount C, the process proceeds to step S8. At step S8, the CPU 13 subtracts the available space A of the first recording medium 4a from the preprogrammed image information amount C to calculate the recording space shortage D, and the value is stored in the recording space shortage storage portion 18.
In the first recording medium space managing portion 5, the image information already recorded on the first recording medium 4a is managed by a predetermined order, for example, by ascending order of recording date and time. When a number, n, of pieces of image information are recorded, the ordinal ranks j thereof are 1, 2, . . . and n, and the corresponding ordinal rank is assigned to each piece of image information for management. For example, the image information name with an ordinal rank J is Vj, and the image information amount with an ordinal rank J is Ej.
At step S9, the ordinal rank J of the image information already recorded on the first recording medium 4a is set to 1. At step S10, the amount E1 of the image information of J=1 is stored in the first recording medium image information amount storage portion 19. At step S11, the recording space shortage D is compared with the information amount Ej stored in the first recording medium image information amount storage portion 19 to determine whether or not the information amount E1 stored in the first recording medium image information amount storage portion 19 is equal to or larger than the recording space shortage D. When the information amount E1 is smaller than the recording space shortage D, the process proceeds to step S12 and whether the ordinal rank J equals n or not is determined. In the case where J equals n, it indicates that an amount of image information equal to or larger than the recording space shortage D is not recorded on the first recording medium 4a, and accordingly the process proceeds to step S14 and a preprogrammed recording error message is displayed on the display portion 8 to notify the user that the contents of programming cannot be recorded. When J does not equal n, at step S13, J is set to J+1. Then, the process returns to step S10 and the amount Ej of the next image information is stored in the first recording medium image information amount storage portion 19. When the information amount Ej is equal to or larger than the recording space shortage D at step S11, the process proceeds to step S15 and the information amount Ej stored in the first recording medium image information amount storage portion 19 is compared with the available space B of the second recording medium 6a to determine whether or not the available space B of the second recording medium 6a is equal to or larger than the information amount Ej. When the available space B of the second recording medium 6a is smaller than the information amount Ej, the process returns to step S13. When the available space B of the second recording medium 6a is equal to or larger than the information amount Ej, the process proceeds to step S16. At step S16, the image information Vj on the first recording medium 4a selected at that time is moved to the second recording medium 6a. 
Here, the processing of moving the image information Vj is as described below, and these controls are all performed by the control portion 2 controlling the first and the second recording apparatuses 4 and 6. The first recording apparatus 4 reads out the image information Vj on the first recording medium 4a and hands over the image information Vj to the second recording apparatus 6. The second recording apparatus 6 records the received image information Vj onto the second recording medium 6a. After all the image information is recorded onto the second recording medium 6a, the image information Vj on the first recording medium 4a is erased.
After the movement of the image information Vj to the second recording medium 6a is finished, at step S17, the content of the movement is displayed on the display portion 8. For example, as shown in FIG. 3, the ordinal rank of the moved image information on the first recording medium 4a and the ordinal rank thereof on the second recording medium 6a after the movement are displayed. In this example, the image information V2 on the first recording medium 4a is moved to the second recording medium 6a and assigned an ordinal rank 3. Lastly, at step S7, the apparatus is brought into the recording standby state, and when the recording time comes, the image information is recorded onto the first recording medium 4a. 
In this manner, an available space of at least equal to or larger than the preprogrammed image information amount can be secured on the first recording medium 4a, so that the image of which recording is preprogrammed by the user is recorded onto the first recording medium 4a without divided.
Moreover, as described above, when an exchangeable medium such as an optical disk is used as the second recording medium 6a, since image storing capability is excellent, the image information can be moved to the second recording medium 6a for storage when the user wants to store some of the image information recorded on the first recording medium 4a, and preprogrammed recording can be performed even when the user wants to perform preprogrammed recording of an image whose information amount is equal to or larger than the available space of the first recording medium 4a. 
Moreover, a plurality of second recording media 6a may be provided like the changer configuration. This increases the possibility that the image information selected to increase the available space of the first recording medium 4a can be moved to the second recording media 6a. In this case, by preprogramming in the control portion 2 which of the recording media the image information on the first recording medium 4a is moved to with priority, the efficiency of use of the second recording media 6a can be increased.
For example, at step S15 of the flowchart of FIG. 2, when the selected image information amount Ej of the first recording medium 4a is compared with the available space B of the second recording medium 6a, as the available space of the second recording medium 6a, a recording medium having a small available space is selected with priority from among the second recording media 6a, and to the medium, the selected image information on the first recording medium 4a is moved.
Moreover, when a larger amount of image information than the recording space shortage is selected from among the pieces of image information recorded on the first recording medium 4a, by selecting a plurality of pieces of image information, the possibility that an available space is created increases. The flowchart in this case is shown in FIG. 4.
The flowchart shown in FIG. 4, in contrast to that of FIG. 2, is provided with additional steps S18 to S22 and S24 to S26 between step S12 and step S14. When J equals n at step S12 of the flowchart of FIG. 2, not an error processing is performed but two pieces of image information are selected from the first recording medium 4a, the sum of the amounts of the two pieces of image information is calculated, and the information amount Fj is stored in the first recording medium image information amount storage portion 19. When the value D of the recording space shortage storage portion 18 is higher, the image information with the ordinal rank 1 and the image information with the ordinal rank 3 are selected next and comparison is performed again. Specifically, at step S18, J is set to 1 and K is set to 2 (K≠J). At step S19, the information amount Fj which is the sum of the information amount Ej and the information amount Ek is stored into the first recording medium image information amount storage portion 19. Then, at step S20, the information amount Fj stored in the first recording medium image information amount storage portion 19 is compared with the recording space shortage D to determine whether or not the information amount Fj is equal to or larger than the recording space shortage D. When the information amount Fj is equal to or larger than the recording space shortage D, the process proceeds to step S15 of FIG. 1. When the information amount Fj is smaller than the recording space shortage D, the process proceeds to step S24. At step S24, whether K equals n or not is determined. When K does not equal n, K is set to K+1, and the process returns to step S19. When K equals n, the process proceeds to step S21 and whether J equals n−1 or not is determined. When J equals n−1, since there is no information amount Fj that is equal to or larger than the recording space shortage D, an error message is displayed, and the processing is ended. When J does not equal n−1, the process proceeds to step S22 and J is set to J+1. Then, the process proceeds to step S26 and K is set to J+1. Then, the process returns to step S19. In addition to the above-described example, three ton pieces of image information may be selected.
Moreover, when the order by which the image information recorded on the first recording medium 4a is managed by the first recording medium space managing portion 5 is decreasing order of image information amount, a large amount of image information is moved to the second recording medium 6a with priority, so that the possibility is obtained that it is unnecessary to move information when recording is preprogrammed next time.
Moreover, when the image information recorded on the second recording medium 6a is reproduced, the reproduction output from the second recording apparatus 6 is output to the output portion 9 of the apparatus.
Further, a recording medium in a recording apparatus connected to the outside through a network may be used as the second recording medium. FIG. 5 shows the structure of the image recording system 20 according to a second embodiment of the invention. Note that, in this embodiment, the components that play the same or corresponding roles in the first embodiment will be identified with the same reference symbols, and overlapping descriptions will be omitted.
