After the capture, the stop of the input / output circuits 14a to 14f may be released to display the video signal on the color display 202, or the still image written in the memory device 1A may be displayed.

The still image captured at this time is, together with a full image represented by the data of all the pixels of one frame of the input moving image video signal, by the pixels extracted at a predetermined ratio from all the pixels. An index image to be expressed is formed, and a descriptor including an arbitrary classification code for search together with these still images is added. Then, these two still images and descriptors are written into the memory device 1A in a predetermined format.

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

The above-mentioned index image is formed by connecting arbitrary hardware to the video bus 11 or

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

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 disk is supplied to the drive device 103, first, a database including classification codes used for retrieval is formed in the workstation 2 from descriptors on the disk [21]. 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 corresponding still image descriptor is read out from the drive device 103 by the still image file means 1 by the searched classification code or the like [ 11].

This descriptor is analyzed [12].
Then, the addresses of the index picture and the full picture are stored [13], and the index picture is read from the drive device 103 according to the analyzed address [14], and the read index picture 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 includes C

For each address of the memory 16M corresponding to each of the hatched ranges (1) to (12) in the upper half of the background image, The above-mentioned index images are sequentially written by the address control [15] and displayed.

By writing all the searched index images into the memory device 1A once, for example, when there are 13 or more index images, access to another display page can be performed at a high speed.

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

Further, according to the determination, the above-mentioned store [1]
3] The addresses of the desired full image and index image of the still image are taken out of the addresses, whereby the full image and index image read from the drive device 103 [16] are written into the memory device 1A, and , 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 range (13) to (24), and the index image and the full image are written in the memory device 1A in that order.

The editing is performed in this manner, 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 on the MO disk.

Further, when transmitting the still picture packet edited as described above, the following is performed.

That is, in the above-described apparatus, for example, the input / output circuit 14a is used for transmission, and
A monitor receiver (not shown) is connected to b. Further, transmission is performed in a state where the edited still image packet is stored in the memory device 1A.

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. With it
The second still image is transferred to the input / output circuit 14b and displayed on the monitor receiver.

Next, in this state, the work station 2
, 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 for display on the monitor receiver. Is done.

The still images of the packets edited in this way are transmitted in order. As described above, when the transmission instruction is issued, the still image to be transmitted first is transmitted via the input / output circuit 14a, and the still image to be transmitted next is transmitted to the input / output circuit 14a. The image is displayed on a monitor (not shown) different from the color display 202 via the display 14b. The operator checks the still image to be transmitted next displayed on the monitor receiver, and when it is determined that there is no need to transmit the still image, via the workstation 2, the operator selects the still image to be transmitted. The sending can also be stopped.

[0048] According to the method the transmission of the image signals of the present embodiment, a plurality of still images 及 obtained by extracting a pixel having a desired frame selected from the input motion video signal at a predetermined ratio
And a plurality of images corresponding to these still images are stored, the stored plurality of still images are displayed simultaneously, a desired plurality of still images are selected from the plurality of simultaneously displayed still images in the order of transmission, and this selection is performed. Are sequentially displayed in the order of transmission, and based on the result selected in the order of transmission, the above-mentioned images are displayed.
Since the images are transmitted, the transmission order can be easily determined so that the context of the images to be transmitted is optimized.

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