In this still image file means (1) and the entire apparatus, when a still image is captured, the following is first performed.

That is, a video signal supplied to any of the input/output circuits (14a) to (14f) is subjected to a predetermined A/D conversion and supplied to the video bus (11), and the signal of this video bus (11) is sent to the interface circuit (14f). 16) and displayed on a high-resolution color display (202).

In this state, when a desired image is displayed, a predetermined instruction is given using the mouse (204), etc., and this instruction is sent to the CPU (201).
) through the still image file means (]) CPU (1
7). In this CPU (17), the video bus (1) of the input/output circuits (14a) to (14f)
1) control data is formed to stop supplying the signal to
Control data are then formed for reading the signals in the interface circuit (16) onto the video bus (11) and writing these signals to the memory device (IA) through the connection circuit (18).

These control data are supplied from the CPU (17) to the connection circuit (18) through the control bus (13), and are also supplied to the input/output circuits (14a) to (14f) and the interface circuits (15) (16). The control data output to the control bus (12) is supplied to the video bus (11) via the bus interface circuit (IB), superimposed on the video signal, and supplied to each circuit. In this case, each of the input/output circuits (14a) to (14f) and the interface circuits (15) and (16) are allotted a predetermined horizontal period within the vertical blanking period, and the bus interface circuit (IB) outputs a reference signal. Source (IC
) The control data is supplied to each circuit by outputting the control data at the timing of a specific horizontal period using a synchronization signal from the respective circuits.

In this way, still images are captured. After the capture, the input/output circuits (14a) to (14f) are stopped and the video signal is displayed on the color display (202), or the still image written in the memory device (IA) is displayed. You can also do this.

Furthermore, the still images captured in this case are combined with a full image consisting of all pixels in one frame to form an index image in which pixels are extracted at a predetermined ratio, and these still images are used in the search. A disc libter containing an arbitrary classification code etc. is added and formed.

These two still images and disc libter are then written into the memory device (IA) in a predetermined format. The format is such that the disc libter, full picture, and index picture are each written in independent areas, and the addresses of the corresponding full picture and index picture are provided within the disc libta. Further, the formation of the above-described index image may be performed by connecting arbitrary hardware to the video bus (11), or may be processed by software using the CPU (17) and the connection circuit (18). In addition, still images captured in the memory device (1^) can be transferred to and stored in an MO disk drive device (103), etc., and this MO disk can also be taken out and used in other similar devices. .

The still image captured in this manner is then edited in the following manner.

That is, FIG. 3 is a functional block diagram. For example, when an MO disk on which a plurality of still images are written as described above is supplied to the drive device (103), a search is first performed from the disk libter on the disk. A database based on the classification codes to be used is created in the workstation (2).
2I] will be carried out. Images based on this database are displayed on the color display (202), and can be searched using the keyboard (203) or mouse (204).
2] is performed, and the still image file means (1) sequentially outputs the corresponding still image disk librators from the drive device (103) according to the searched classification code and the like [11].

This disc libter is analyzed [12], the addresses of the index picture and full picture are stored (13), and the drive is installed according to the analyzed address. (103
) are successively read out [14], and this read index picture is transferred to the memory device f(IA). The index picture transferred to this memory device (1^) is further transferred to the interface circuit (16).

Here, the interface circuit (16) is provided with an image memory (16M) corresponding to, for example, all pixels of the color display (202), and the CPU (201)
For example, a background image as shown in FIG. 4 is formed by the signals supplied from the. Then, address system 1 (
15), the above-mentioned index images are sequentially written and displayed. By temporarily writing all searched index images to the memory device (IA), it is possible to access another displayed page at high speed, for example, when there are 13 or more index images.

On the other hand, the lower half of the background image is also marked with a diagonal line.
phase] is provided. Then, use the mouse (204
) etc. to move an arbitrary cursor (not shown) within the desired still image range and then perform any key operation, etc., the still image corresponding to that range is determined on the workstation (2). [23], and according to the determination, the addresses of the desired full still image and index picture are taken out from the addresses stored [13] above, and read out from the drive device (103) [16]. The full image and index image are written to the memory device (IA), and the index image is written to the address of the memory (16M) corresponding to the range @ and displayed.

By repeating this operation, the range @ ~ [
The index images of the desired still images are displayed one after another in [Phase].
The index image, full image, and disc libter of this still image are written into the memory device (14). Here, the disc libter written to the memory device f (IA) is provided with an arbitrary link pointer in addition to the above-mentioned classification code for searching, etc., and stops in the order of selection from the above-mentioned range ■ ~ @. The address of the disc libter of the next still image is sequentially written in this link pointer so that the images are linked.

Then, while performing any editing, the range of the display surface @
By moving the above-mentioned cursor to the position of ~[phase] and performing an arbitrary key operation there, the arrangement of the still images displayed in the range @~[phase] can be arbitrarily changed.

That is, when moving a still image, the above-described operation is first performed within the range of the still image to be moved, and then the operation is performed within the range of the movement destination. As a result, in the above functional block, when the workstation (2) first determines the range in which the operation was performed [23], the link pointer of the still image disc libter corresponding to the range before this range is moved to the next one. The address of the still image disc libter corresponding to the range is rewritten [17], and the range in which the operation was performed is then determined [2].
3], the link pointer of the still image disc libter corresponding to the range before this range is rewritten to the address of the still image disc libter to be moved [17], and the link pointer of the still image disc libter corresponding to the range before this range is rewritten to the address of the still image disc libter to be moved. The pointer is rewritten [17] to the address of the still image disc libter corresponding to the range in which the next operation was performed.

Therefore, when display is performed using this rewritten link pointer, the first operated still image is deleted, this still image is inserted before the next operated still image, and the still image is moved.

In the same manner, still images can be replaced, deleted, inserted, etc.

In addition, when copying the same still image, the range of the still image to be copied is determined by the workstation (2) by performing the above operations [23], and then the above-mentioned storage is performed according to this determination. The addresses of the desired full still image and index image are read out from the addresses [13], and the drive device (103) is then read out [16] and the full image and index image are stored in the memory device (IA). At the same time, the address of the disc printer of this still picture is written to the link pointer of the disc printer of the final selected still picture.

As a result, the arrangement of the still images displayed in the range 1 to [phase] on the display screen is arbitrarily changed, and the sending order of the still images is changed by rewriting the link pointer of the disk printer. In this case, the actual operation is only to rewrite the link pointer, and the arrangement of still images can be changed extremely easily.

Editing is performed in this way, and the still image packets arranged in the desired transmission order are stored in the memory device (IA).
will be completed in This packet also contains a drive device (10
3) and save it on the MO disk.

Further, when transmitting a still image packet edited as described above, the following procedure is performed.

That is, in the above-mentioned device, for example, the input/output circuit (14
a) is used for transmission, and a monitor receiver (not shown) is connected to the input/output circuit (14b). Further, the packet of the edited still image described above is sent out while being stored in the memory device (l^). First, when a transmission instruction is issued from the workstation (2), the first still image of the packet is transferred to the input/output circuit (14a) and transmitted, and the second still image is transmitted to the input/output circuit (14a).
4b) and displayed on the monitor receiver. Next, when the workstation (2) issues a transmission instruction again in this state, the second still image of the packet will be sent to the input/output circuit (
At the same time, the third still image is transferred to the input/output circuit (14b) and displayed on the monitor receiver.

The still images of the packets edited in this way are sent out in order. In this case, the still image to be sent next is displayed on the monitor receiver, and 5. If the user sees this display and finds that the next still image is not needed, processing such as deletion of the next still image can be performed in response to an instruction from the workstation (2).

In this way, according to the above-mentioned device, the original still image is displayed on one of the divided display screens, the selected still image is displayed on the other, and the arrangement of the selected still image is arbitrarily changed. By doing so, editing of still images can be performed extremely smoothly.

In addition, in the above device, when any still image is selected in the range ■~@, the index image in that range is deleted, the index images in the following ranges are moved up sequentially, and the first page of the next page is displayed. The index picture of @
It may also be displayed in .

Furthermore, the division of the display screen is not limited to the upper and lower divisions as described above.
It can also be divided into left and right halves.

Furthermore, in the above-described apparatus, the still image may be provided with a key image (one pixel, one bit) for performing so-called key synthesis, in addition to the full image and the index image.

〔Effect of the invention〕

According to this invention, the original still image is displayed on one of the divided display screens, the selected still image is displayed on the other, and the arrangement of the selected still image is arbitrarily changed. This makes editing of still images extremely smooth.
