Therefore, on the display surface of the color display (202), for example, as shown in FIG. 4, video signals from the input / output circuits (14a) to (14f) are displayed on a part of the display surface with cross hatching. Then, a still image from the connection circuit (18) and the like are displayed in the other hatched portions, and an image formed by the CPU (201) is displayed in the other portions.
Then, in this case, the VTR
The image of the operation unit of (6) is displayed.

Therefore, in the still image file means (1) and the entire apparatus, the still image is captured as follows.

That is, first, an arbitrary cursor (not shown) is moved to the position of the image of the operation section of the VTR with the mouse (204) or the like, and a predetermined key operation or the like is performed at the position of the arbitrary operation button. The operation button is determined in the station (2), and control data necessary for the operation is formed.

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

On the other hand, the lower half of the background is shaded
Is provided. Then, while an index image is displayed in each of the above-mentioned ranges, an arbitrary cursor (not shown) is moved into a desired still image range with a mouse (204) or the like, and an arbitrary key operation or the like is performed there. Then, the still image corresponding to the range is determined [23] at the workstation (2), and the addresses of the full image and the index image of the desired still image are selected from the addresses stored in accordance with the determination [23]. The full picture and the index picture read [16] from the drive device (103) are written to the memory device (1A), and the index picture is written to the address of the memory (16M) corresponding to the range. It is rarely displayed.

By repeating this operation,

a) is for transmission, and a monitor receiver (not shown) is connected to the input / output circuit (14b). Further, transmission is performed in a state where the edited still image packet is stored in the memory device (1A). When the workstation (2) first issues a transmission instruction, the first still image of the packet is transferred to the input / output circuit (14a) for transmission, and the second still image is transmitted to the input / output circuit (14b). And displayed on the monitor receiver. Next, in this state, when a transmission instruction is issued again from the workstation (2), the second still image of the packet is transferred to the input / output circuit (14a), and the packet is transmitted. The data is transferred to the output circuit (14b) and displayed on the monitor receiver.

The still images of the packets edited in this way are sequentially transmitted. In this case, a still image to be transmitted next is displayed on the monitor receiver, and when the next still image is unnecessary after seeing this display, the next still image is transmitted by an instruction from the workstation (2). Processing such as deletion can also be performed.

Thus, according to the above-described apparatus, the image of the operation unit of the video device is displayed on the display surface, and the video device is controlled by instructing the image, so that the capture of a still image and the like can be performed extremely smoothly. You can do it.
