Is supplied to. Then, the signal from the control circuit 162 is supplied to the address control circuits 163M and 163S to control writing and reading of data in the memories 16M and 16S, respectively.

As a result, a display image such as a still image previously captured by the signal from the connection circuit 18 is formed in the memory 16M. On the other hand, in the memory 16S, the video signal supplied to any of the input / output circuits 14a to 14f is subjected to predetermined A / D conversion and supplied to the video bus 11, and this video signal is sequentially written.

These control data are supplied from the CPU 17 to the connection circuit 18 through the control bus 13 and output to the control bus 12 for the input / output circuits 14a to 14f and the interface circuits 15 and 16. The data is supplied to the video bus 11 via the bus interface circuit 1B, is superimposed on the video signal, and is supplied to each circuit.

That is, in this case, each input / output circuit 14a
14f and the interface circuits 15 and 16 are assigned a predetermined horizontal period within the vertical blanking period. Then, the control data is supplied to each circuit by outputting control data at the timing of each specific horizontal period in accordance with the synchronization signal from the reference signal source 1C in the bus interface circuit 1B.

In this way, the still image is captured.
After the capturing, the input / output circuits 14a to 14f may be released from the stop and the video signal may be displayed on the color display 202 or the still image written in the memory device 1A may be displayed.

Further, the still image captured at this time is formed with an index image in which pixels are extracted at a predetermined ratio together with a full image of all pixels in one frame, and is searched together with these still images. A descriptor including an arbitrary classification code for is added and formed.
Then, these two still images and descriptors are written in the memory device 1A in a predetermined format.

As a writing format, the descriptor, the full image and the index image are written in independent areas, respectively, and the addresses of the corresponding full image and the index image are provided in the descriptor.

The above-mentioned index picture is formed by connecting arbitrary hardware to the video bus 11 or by using CP.

Further, the still image thus captured is edited as follows.

That is, FIG. 5 is a functional block diagram.
For example, an MO in which a plurality of still images are written as described above.
When the disc is supplied to the drive device 103, first, a database is formed [21] by the workstation 2 from the descriptors on the disc, such as a classification code used for retrieval. An image based on this database is displayed on the color display 202.

On the other hand, when the search [22] is performed by the keyboard 203 or the mouse 204, the still image file means 1 reads the corresponding still image descriptor from the drive device 103 by the retrieved classification code or the like. 11] is performed.

This descriptor is analyzed [12].
Then, the addresses of the index image and the full image are stored [13], the index image is read [14] from the drive device 103 according to the analyzed address, and the read index image is transferred to the memory device 1A. . The index image transferred to the memory device 1A is further transferred to the interface circuit 16.

Here, the interface circuit 16 has a C
For example, a background image as shown in FIG. 6 is supplied from the PU 201, and each address of the memory 16M corresponding to each range (1) to (12) hatched in the upper half of the background image, The above-mentioned index images are sequentially written and displayed by the address control [15].

By writing all the retrieved index images in the memory device 1A once, for example, when there are 13 or more index images, another page displayed can be accessed at high speed.

On the other hand, ranges (13) to (24) are also provided in the lower half of the background image as hatched. Then, while the index image is displayed in each of the above ranges (1) to (12), an arbitrary cursor (not shown) is moved by the mouse 204 or the like into a desired still image range, and an arbitrary key is operated there. By doing so, the still image corresponding to the range is discriminated [23] in the workstation 2.

Further, according to the determination, the above-mentioned store [1
3] The addresses of the desired still image full image and index image are extracted from the read addresses, and the full image and index image read [16] from the drive device 103 are written in the memory device 1A. , The index image is written and displayed at the address of the memory 16M corresponding to the range (13).

By repeating this operation, index images of desired still images are sequentially displayed in the ranges (13) to (24), and the index images and full images are written in the memory device 1A in that order.

The editing is performed in this way, whereby the still image packets arranged in the desired transmission order are completed in the memory device 1A. This packet can also be transferred to the drive device 103 and stored in the MO disk.

Further, in the case of transmitting the packet of the still picture edited as described above, it is carried out as follows.

That is, in the above-mentioned apparatus, for example, the input / output circuit 14a is used for sending, and the input / output circuit 14a is used.
A monitor receiver (not shown) is connected to b. Further, the packet of the edited still image is transmitted while being stored in the memory device 1A.

When the sending instruction is issued from the work station 2, the first still image of the packet is transferred to the input / output circuit 14a and sent. Along with that
The second still image is transferred to the input / output circuit 14b and displayed on the monitor receiver.

Next, in this state, the workstation 2 again
When a transmission instruction from the packet is issued, the second still image of the packet is transferred to the input / output circuit 14a for transmission, and the third still image is transferred to the input / output circuit 14b and displayed on the monitor receiver. To be done.

The still images of the packets edited in this way are transmitted in order. In this case, the still image to be sent next is displayed on the monitor receiver, and if the next still image is not needed when looking at this display, the next still image is deleted by an instruction from the workstation 2. Can also be processed.

Thus, according to the above-mentioned editing device, a plurality of still images selected from the input video signal and stored by the storage means are displayed in the first display area of the display means and displayed in the first display area. By selecting a desired still image from a plurality of still images and displaying it in the second display area of the display means, the editing work can be facilitated and the desired editing work can be easily performed by a simple procedure. Is.

In the above apparatus, a still image may be provided with a full image and an index image, as well as a key image (1 pixel 1 bit) for so-called key combination.
