BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing system for performing data processing on n storage devices connected between a data transfer source and a data transfer destination under the control of a control unit, and a data processing method in this system. The present invention also relates to a data processing key input device for causing the control unit to perform the above data processing by key operation.

2. Description of the Related Art Recently, development of a data processing system for selecting only desired data from a large amount of continuously supplied data and storing it in a storage device has been underway.
In particular, recently, a system has been proposed in which a large number of storage devices are connected so that not only one data but also a plurality of data can be stored, and each storage device stores selected desired data. ing.

Such a system is used as, for example, a device for creating background image data of a game program or a device for video editing, and is put to practical use in, for example, a video printer. These devices store only the video as a still image in a storage device when a video image that suits the user's preference is displayed from the moving image data that is continuously transferred, and then the storage device stores it. The stored still image is used as background image data of a game program, as embedded image data in video editing, or is printed on photographic paper or copy paper for output.

As a conventional control method for a large number of storage devices, one storage device out of a large number of storage devices (for convenience, referred to as n storage devices) is used for temporary storage of data. The data stored in the storage device for storage is controlled to be stored in, for example, one storage device selected from the n-1 storage devices.

Specifically, the storage device selected for temporary storage is connected between the transfer source of the moving image data and the monitor displaying the moving image data as a video, and the moving image is constantly stored in the storage device. Data is supplied, and when the desired image is displayed, the still image data is stored in the storage device, and then the still image data stored in the storage device is transferred to another storage device. I am trying to let you.

It is possible to effectively prevent the arbitrary storage device M from entering the data fixed state or the data update resuming state by operating 5, and the reliability of the key operation can be improved.

When the data transferred from the data transfer source is the moving image data Di and the data written in the predetermined storage area 33 of the storage device M is the still image data Ds for one frame, for example, It becomes possible to store a desired image as still image data Ds in any storage device M while watching the moving image displayed on the monitor connected to the data transfer destination, and the background image data and the video of the game program can be stored. It is possible to easily create still image data to be incorporated into video data in editing and to be supplied to a video printer. Moreover, since the still image data Ds can be stored in the n storage devices M, a large amount of still image data Ds can be created from one continuous moving image data Di.

Next, in the data processing key input device 2 according to the present invention, one or a plurality of the storage devices M among the n storage devices M are operated according to the key operation on the first key operation group 2A. Will be selected. Then, in accordance with the key operation on the enter key 24 of the second key operation group 2B, the data from the data transfer source in the selected storage device M is written in the predetermined storage area 33,
The data update operation for updating the data in the transfer sequence is stopped, and the data is fixed.

As described above, the keys for selecting the storage device M are arranged in the first key operation group 2A, and the confirm key 24 for causing the selected storage device M to confirm the data is the first key. A total of a superordinate conceptual one behavior of selecting the storage device M and a subordinate conceptual behavior of performing a specific operation designation for the selected storage device M, which are arranged in the two key operation groups 2B. 2 behavior, any storage device M

The selected storage device M is a subordinate conceptual behavior of specifying a specific operation for the selected storage device M.
To the specific action (in this case, restarting the data update)
The key operation becomes very easy.

In the first key operation group 2A, key input data for directly transferring the data from the data transfer source to the data transfer destination is generated and the device non-selection key 21 to be input to the control unit 1 is generated. In the case of disposing, the data from the data transfer source is directly transferred to the data transfer destination without the storage device M by operating the device non-selection key 21.

In the image memory 33, the moving image data Di input through the input terminal φin and the contact point a is written while undergoing data compression processing, and the data is updated sequentially in the transfer. Each storage device M1
And M2 will output the restored moving image data Di.

Next, in step S4, the initial state setting means 42 outputs a bypass line selection signal for selecting the bypass line L to the selector 3 via the output port 15. The selector 3 electrically connects the movable contact 3c and the fixed bypass contact 3z based on the input of the bypass line selection signal from the microcomputer 4.

As a result, the moving image data Di input to the input terminal φin is directly output from the output terminal φout. In addition, data indicating no device selection (bypass line selection) is stored in the device selection information area through the initial state setting means 42. This data is the same as the content of the key input data input to the microcomputer 4 when the THRU key 21 arranged on the operation panel of the key input device 2 is operated, for example. This state indicates that the THRU stage 51 is currently set in the state transition diagram of FIG.

Next, in step S5, the discrimination means 4
Through 3, the key input device 2 determines whether or not the key input data is supplied. This determination is performed until key input data is input from the key input device 2. That is, the key input is awaited.

When the key input data is input from the key input device 2 in the above step S5, the process proceeds to the next step S6 and the data regarding the device currently selected is taken out from the device selection information area of the data RAM 13.

Next, in step S7, whether the content of the key input data input this time is related to device selection (bypass line selection, first storage device selection, second storage device selection) through the key determination means 44. It is determined whether or not. If the content of the key input data relates to the device selection, the process proceeds to the next step S8, and the discriminating means 43 discriminates whether or not the present device selection is the same as the currently selected device. This determination is made by comparing the content of the data stored in the device selection information area with the content of the key input data input this time.

If the device selected this time is not the same as the one currently selected, the process proceeds to the next step S9, and the THRU keys 21, M1 arranged on the operation panel of the key input device 2 are selected.
Of the keys 22 and M2 key 23, a turn-off request signal is output to the key input device 2 to turn off the currently selected key (while being turned on). The key input device 2 stops the lighting output of the currently selected key among the above keys based on the input of the turn-off request signal from the microcomputer 4.

Next, in step S10, the key input data input this time is stored in the device selection information area.

Next, in step S11 of FIG. 7, the key discriminating means 44 discriminates whether or not the key input data this time relates to the selection of the storage device M1 or M2. If it is related to the selection of the storage device M1 or M2, the process proceeds to the next step S12, and the device selection means 46 outputs a device selection signal for selecting the corresponding storage device M1 or M2 to the selector 3. The selector 3 electrically connects the movable contact 3c to the fixed contact 3a or 3b on the side of the memory device M1 or M2 that has been selected this time based on the input of the device selection signal from the microcomputer 4. As a result, the output (moving image data Di or still image data Ds) from the storage device M1 or M2 selected this time is taken out from the output terminal φout via the selector 3.

This state is as shown in the state transition diagram of FIG.
If the M1 key 22 is operated this time, it indicates that the state has transitioned from the THRU stage 51 or the M2 stage 53 to the M1 stage 52. If the M2 key 23 is operated this time, the THRU stage 51 or the M1 stage 52 is operated.
Indicates that the state has changed from the M2 stage 53 to the M2 stage 53.

Next, in step S13, a key lighting request signal for lighting the currently selected key (M1 key 22 or M2 key 23) to the key input device 2 is output through the device selection means 46. To do. Key input device 2
Is the key (M1 key 22 or M2 key 2) selected this time based on the input of the key lighting request signal from the microcomputer 4.
Lighting output is performed for 3).

Next, in step S14, the discrimination means 43 discriminates whether or not there is a program end request. This determination is made based on whether or not there is a termination request, for example, when the power is turned off or a maintenance interrupt (which is performed when a new program is ported in an online environment based on function addition etc.). If there is an end request, the data processing program 41 ends. If there is no end request, the process returns to step S5 of FIG. 6 again to wait for the next key input.

On the other hand, if it is determined in step S11 of FIG. 7 that the key input data this time is related to the selection of the bypass line L (device non-selection), the process proceeds to the next step S15 and the device selection means 46 is used. , And outputs a device selection signal for selecting the bypass line L to the selector 3. The selector 3 electrically connects the movable contact 3c and the bypass line fixed contact 3z based on the input of the device selection signal from the microcomputer 4. As a result, the moving image data Di input to the input terminal φin is directly taken out from the output terminal φout. This state is
The state transition diagram of FIG. 5 shows that the THRU key 21 is operated this time, whereby the state is changed from the M1 stage 52 or the M2 stage 53 to the THRU stage 51.

Next, in step S16, the key (THRU key 2) selected this time with respect to the key input device 2 is selected.
A key lighting request signal for lighting 1) is output through the device selecting means 46. The key input device 2 outputs a lighting output to the key (THRU key 21) selected this time based on the input of the key lighting request signal from the microcomputer 4.

After the processing of step S16 is completed,
When it is determined in step S8 in FIG. 6 that the current device selection is the same as the currently selected one, the process proceeds to step S14 in FIG. 7 and the termination request is determined as described above. .

On the other hand, in step S7 of FIG.
When it is determined that the content of the key input data input this time is not related to the device selection but the GRAB key 24 or the RELEASE key 25, the process proceeds to step S21 of FIG. It is determined whether or not it is selected. This determination is based on FIG.
This is performed based on the data in the device selection information area extracted in step S6.

If the data in the device selection information area relates to the storage device, the next step S22 in FIG.
Then, the key discriminating means 44 discriminates whether or not the key input data this time relates to the GRAB key 24. If it relates to the GRAB key 24, the process proceeds to the next step S23, and the discriminating means 43 discriminates whether or not the currently selected storage device M1 or M2 is outputting the moving image data Di. This determination is made based on whether or not the corresponding bit of the device status flag is "0".

If the corresponding bit is "0" and the moving image data is currently being output, the process proceeds to the next step S24, and the data determining means 47 sets the corresponding bit of the apparatus state flag to "1" and the still image is stopped. Set to the image output state. That is,
Set bit processing is performed on the corresponding bit of the device status flag.

Next, in step S25, the data confirmation instruction signal Ss is output to the currently selected storage device M1 or M2. When the data confirmation instruction signal Ss from the microcomputer 4 is input, the corresponding storage device M1 or M2 stops writing the subsequent data when the compressed data currently being written in the image memory 33 reaches one frame. To do. Therefore, only one frame of compressed data stored in the image memory 33 is decompressed by the data decompression circuit 32 and fetched as still image data Ds from the output terminal φout via the selector 3.

This state is as shown in the state transition diagram of FIG.
The currently selected storage device is, for example, the first storage device M.
1 and currently in M1 stage 52, GRAB
By operating the key 24, it is indicated that the state of M1-MOVE 55 has changed to the state of M1-STILL 54, and the currently selected storage device is the second storage device M.
2 and is currently on the M2 stage 53, by operating the GRAB key 24, M2-M
This shows that the state of OVE57 has transited to the state of M2-STILL56.

Next, in step S26, the two display elements (L
Of the EDs 26 and 27, a lighting request signal is output to the key input device 2 to light the display element 26 or 27 corresponding to the currently selected storage device M1 or M2. The key input device 2 outputs a lighting output to the corresponding display element 26 or 27 based on the input of the lighting request signal from the microcomputer 4.

On the other hand, in step S23, if the corresponding bit of the device status flag is "1" and the currently selected storage device M1 or M2 is in the still image data output state, the process proceeds to step S27, and the data confirmation means is executed. Through 47, the one-time data update instruction signal Sss is output to the currently selected storage device M1 or M2.

The corresponding storage device M1 or M2 is the microcomputer 4
Based on the input of the one-time data update instruction signal Sss from, the input of one frame of the current moving image data Di supplied to the input terminal φin is permitted, and the image memory 3
The compressed data for one frame is written in 3. When the writing of one frame of the compressed data is completed, the writing of the subsequent data is stopped. Therefore, the image memory 33
Only the latest compressed data for one frame stored in the data decompression circuit 32 is decompressed by the data decompression circuit 32 and output to the selector 3 side as the still image data Ds.

This state is as shown in the state transition diagram of FIG.
The currently selected storage device is, for example, the first storage device M.
1 and currently in M1 stage 52, GRAB
By operating the key 24, M1-STILL54
Indicating that the state has changed to the state of M1-STILL 54 again, and the GRAB key 24 is operated even when the currently selected storage device is the second storage device M2 and is currently in the M2 stage 53. By M2
-M2-STILL56 from the state of STILL56 again
This indicates that the state has transitioned to.

When it is determined in the above step 22 that the key input data this time is related to the RELEASE key 25, the process proceeds to the next step S28, and the corresponding bit of the device status flag is set to "0" through the data update resuming means 48. Reset to and set to the moving image output state. That is, the reset bit process is performed on the corresponding bit of the device status flag.

Then, in step S29, the data update instruction signal Sc is output to the currently selected storage device M1 or M2. The corresponding storage device M1 or M2, based on the input of the data update instruction signal Sc from the microcomputer 4,

i is once subjected to data compression processing and decompression processing in the storage device M1 or M2, and is output via the selector 3 to the output terminal φou.
It will be taken out from t.

This state is as shown in the state transition diagram of FIG.
The currently selected storage device is, for example, the first storage device M.

By operating the ASE key 25, M1-STIL
When the state of L54 is changed to the state of M1-MOVE55, and the currently selected storage device is the second storage device M2 and is currently in the M2 stage 53, the RELEASE key 25 is operated. As a result, from the state of M2-STILL56 to M2-MOVE5
This indicates that the state has transitioned to state 7.

Next, in step S30, the two display elements (L
ED) 26 or 27, a turn-off request signal is output to the key input device 2 to turn off the display element 26 or 27 corresponding to the currently selected storage device M1 or M2. The key input device 2 stops the lighting output to the corresponding display element 26 or 27 based on the input of the above-mentioned turn-off request signal from the microcomputer 4.

Then, the above steps S26 and S
When either the process of 27 or step S29 is completed, the process proceeds to step S14 of FIG. 7 and the determination of the end request is made as described above.

On the other hand, if the bypass line L is currently selected in step S21 of FIG. 8, the process directly proceeds to step S14 of FIG. 7 and the GRAB key 2 is pressed.
4 or the operation input of the RELEASE key 25 becomes invalid.

The operation of the data processing system according to this embodiment by the data processing program 41 will be briefly described below in relation to the key input operation on the key input device 2.

First, when the data processing system is in the state of the THRU stage 51 and the M1 key 22 is operated, the state of the system is changed to the M1 stage 52.

At the M1 stage 52, M
In the case of 1-STILL 54, the still image data Ds is output from the first storage device M1, and the first display element 26 of the operation panel is on.

When the GRAB key 24 is operated in this state, still image data Ds for one still image (one frame) is written in the image memory 33, and writing of data to the image memory 33 thereafter is stopped.

After that, when the RELEASE key 25 is operated, the state transits to M1-MOVE 55 and the data writing to the image memory 33 is restarted. At this time, the first display element 26 on the operation panel is turned off.

Then, in the state of M1-MOVE55, GR
When the AB key 24 is operated, the image data Di for one sheet at that moment is written in the image memory 33, and thereafter the data writing is stopped. At this time, the first display element 26 on the operation panel lights up.

Next, when the M2 key 23 is operated in the M1 stage (arbitrary state) 52, the second storage device M2 is currently in the output state of the still image data Ds,
When the second display element 27 on the operation panel is lit, the state transitions to M2-STILL 56, and 1 stored in the image memory 33 of the second storage device M2 in advance.
The still image data Ds for the frame is output from the output terminal φout via the selector 3.

On the other hand, when the second storage device M2 is currently in the output state of the moving image data Di and the second display element 27 on the operation panel is off, M2-MOV
The state transitions to E57, and the moving image data Di is output from the second storage device M2.

Further, from the M1 stage (arbitrary state) 52 or the M2 stage (arbitrary state) 53 to the THRU key 2
When 1 is operated, the state transits to the THRU stage 51, and the input moving image data Di supplied to the input terminal φin is directly output from the output terminal φout.

As described above, in the data processing system according to the above-mentioned embodiment, all the two storage devices M1 and M2 connected between the input terminal φin and the output terminal φout to which the input moving image data Di are supplied are connected. It can be handled in the same row, and two kinds of desired data can be determined.

Particularly, based on the key input data associated with the operation of the RELEASE key 25 arranged in the second key operation group 2B of the key input device 2, a data update instruction signal is sent to the currently selected storage device M1 or M2. Since Sc is output to restart the data update by the memory controller 34 of the storage device M1 or M2, the moving image data Di from the input terminal φin is sent to the storage device M1 or M2 whose data has been determined. The data transferred and written in the image memory 33 is sequentially updated in the transfer.
That is, the confirmation of the data is released, and the operation can be performed toward the confirmation of the next desired data.

Further, based on the input of key input data accompanying the operation of the THRU key 21 arranged in the first key operation group 2A of the key input device 2, the data from the input terminal φin is passed through the bypass line L. Since the data is directly transferred to the output terminal φout, the data compression circuit 31 is connected to the input stage of each of the storage devices M1 and M2, and the storage devices M1 and M2 are connected.
It becomes meaningful when the data written in the image memory 33 is compressed data compressed by the data compression circuit 31.

For example, by comparing the data after decompressing the compressed data with the data transferred directly to the output terminal φout via the bypass line L, for example, when the data is the moving image data Di, the data is displayed on the monitor. It is possible to quantitatively investigate how much data is destroyed by compression from the image displayed on.

Further, the operation input of the GRAB key 24 and the RELEASE key 25 in the key input device 2 is invalidated based on the input of the key input data accompanying the operation of the THRU key 21, so that the input terminal φin is supplied. The output data is directly output via the bypass line L to the output terminal φo.
In the state of being transferred to ut, the GRAB key 24 or RELE in the second key operation group 2B is erroneously operated.
By operating the ASE key 25, any storage device M1 or M2
Can be effectively prevented from entering the data fixed state or the data update resuming state, and the reliability of the key operation can be improved.

Since the data supplied to the input terminal φin is the moving image data Di and the data written in the image memory 33 of each of the storage devices M1 and M2 is the still image data Ds for one frame, for example, the output terminal φo
a desired image while watching a moving image displayed on a monitor (not shown) connected to ut.
1 or M2 can be stored as still image data Ds, and background image data of a game program or image data in video editing can be incorporated and still image data to be supplied to a video printer can be easily created. Moreover, since the still image data can be stored in the two storage devices, a plurality of still image data Ds can be created from one moving image data Di.

A data compression circuit 31 is provided at the input stage of each of the storage devices M1 and M2, and the data written in the image memory 33 of each of the storage devices M1 and M2 is compressed by the data compression circuit 31. Therefore, the storage capacity of the image memory 33 can be reduced, which can contribute to the reduction of manufacturing cost.

Since the data decompression circuit 32 is connected to the output stage of each of the storage devices M1 and M2, for example, the storage devices M1 and M2 having different data compression methods are used.
Can be connected in the same row, and the system itself can be made versatile. Moreover, the input moving image data Di is directly output via the bypass line L to the output terminal φou.

That is, in the above-described data processing system in which the plurality of storage devices M1 and M2 are connected, it is possible to realize the operability in which the key operation is very simple and the key operation is very simple with the necessary minimum key arrangement.

Further, the second key operation group 2B is provided with a RELEASE key 25 for generating key input data for resuming the data update of the selected storage device M1 or M2 and inputting it to the control unit 1. Therefore, as in the case of the GRAB key 24, the selected storage device M is operated in a subordinate conceptual behavior of specifying a specific operation for the selected storage device M1 or M2.
A specific operation (in this case, resumption of data update) is performed for 1 or M2, and the key operation becomes very simple.

The THRU key for causing the first key operation group 2A to generate key input data for transferring the input moving image data Di from the input terminal φin directly to the output terminal φout and input the generated key input to the control unit 1. 21 is arranged, the T arranged in the first key operation group 2A is arranged.
The input motion image data Di from the input terminal φin can be directly transferred to the output terminal φout without passing through the storage devices M1 and M2 by the operation of one action on the HRU key 21, and the key operation is very simple. It is possible to realize easy-to-use operability.

Further, of the two storage devices M1 and M2, the first and second display elements 26 and 27 for displaying the storage device in which the data is determined in a predetermined display form are arranged. Therefore, the existence of the storage device in which the data is being determined can be confirmed at a glance, unnecessary selection for the storage device in which the data is being determined can be prevented in advance, and unnecessary key operation can be avoided. it can.

In the data processing system according to the above embodiment, the two storage devices M1 and M2 are connected in parallel between the input terminal φin and the output terminal φout, but three or more storage devices are connected in parallel. It can also be applied when connected to. In this case, on the data processing program 41, it is sufficient to assign the device status flags assigned to the data RAM 13 to the bits corresponding to the number of storage devices.
