In this still image file means (1) and the entire apparatus, still images are taken in as follows.

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 is supplied to the tech bus (11), and the signal of this video bus (11) is sent to the interface circuit (16). image memory (1

) is displayed on a part of the screen. Also, at this time, arbitrary information images etc. from the CPU (201) are displayed on other parts of the display screen.

In this state, when a desired image is selected, a predetermined instruction is given using the mouse (204), etc., and this instruction is sent to the CPU (17) of the still image file means (1) through the CPU (201).
supplied to In this CPU (17), the video bus (11) of the input/output circuits (14a) to (14f)
Control data are formed to stop the supply of signals to the interface circuit (16) and then to read the signals in the interface circuit (16) onto the video bus (11) and write this signal to the memory device (IA) through the connection circuit (18). Control data is formed. Note that these control data are stored in the CPU (17)
is supplied to the connection circuit (18) through the control bus (13), and output to the control bus (12) to the input/output circuits (14a) to (14f) and interface circuits (15) and (16). The control data 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. Control data is supplied to each circuit by outputting control data at the timing of a specific horizontal period using a synchronization signal from a source (IC).

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.

In addition, the still images captured in this case form an index image in which pixels are extracted at a predetermined ratio together with a full image made up of all pixels in one frame, 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).

Further, the still image captured in this manner is edited as follows.

That is, FIG. 5 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 on the workstation (2).
21] will be done. Images based on this database are displayed on the color display (202), and can be searched using the keyboard (203) or mouse (204).

The above-mentioned index images are sequentially written and displayed by address control [15]. Note that 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 are thereby successively outputted [16] from the drive device (103). The full picture and the index picture are written to the memory device H (IA), and the index picture is written to the address of the memory (16M) corresponding to the range (1) 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 picture and full picture are stored in the memory device (I) in that order.
A).

In this way, fffl is performed, and packets of still images arranged in the desired transmission order are transferred to the memory device (I).
A) will be completed. This packet also contains the drive device (
103) 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 edited still image packet described above is sent out while being stored in the memory device (IA). 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 by looking at this display, you can select the next still image.
When both still images are unnecessary, processing such as deletion of the next still image can be performed in response to instructions from the workstation (2).

Thus, according to the above-mentioned apparatus, by setting a predetermined range of the image from the workstation to a predetermined black level and superimposing the image from the still image file means on this black level range, the image can be displayed on the display surface of the color display. It is possible to display images extremely well.

In the above-mentioned apparatus, a still image may include a full image and an index image, as well as a key image (one pixel, one bit) for performing so-called key synthesis.
