Reference numeral 1D denotes an expansion connection circuit.
[0018]
Further, in the still image file means 1, the above-described interface circuit 16 is configured as shown in FIG.
[0019]
That is, in FIG. 3, the interface circuit 16 includes a first image memory 16M capable of storing all the high-resolution pixels of the color display 202, and a second image memory 16S having a capacity of one frame of the input moving image video signal. The data of the video bus 11 is supplied to these memories 16M and 16S.
[0020]
Further, data on the video bus 11 is supplied to an extraction circuit 161 for a predetermined assigned horizontal period in a vertical blanking period described later, and control data superimposed on the extracted horizontal period is supplied to the control circuit 162. The A signal from the control circuit 162 is supplied to the address control circuits 163M and 163S, and data writing and reading in the memories 16M and 16S are controlled.
[0021]
As a result, the memory 16M receives, for example, a plurality of still images obtained by extracting pixels of a desired frame of the input moving image video signal at a predetermined ratio in advance with a signal from the connection circuit 18, for example. The still image is displayed on the portion of the display surface of the color display 202 shown in FIG. On the other hand, the input moving image video signal supplied to any of the input / output circuits 14a to 14f is A / D converted and supplied to the video bus 11 in the memory 16S, and the input moving image video signal is sequentially written.
[0022]
The signals written in these memories 16M and 16S are read out by signals from the control circuit 162, and the read signals are switched by the switch 164 and synthesized. The combined signal is supplied to the mixer 166 through the D / A converter 165, combined with the signal from the CPU 201 supplied to the terminal 167, and output to the color display 202 through the terminal 168. As a result, the input moving image video signal supplied from the memory 16S is displayed in the cross-hatched portion shown in FIG. 4, and a plurality of pixels obtained by extracting pixels of a desired frame of the input moving image video signal at a predetermined ratio. A plurality of still images read from the memory 16M storing the still images are displayed in a portion indicated by oblique hatching shown in FIG. Further, the signal from the CPU 201 is synthesized by the mixer 166, and the signal from the CPU 201 is displayed on the color display 202 as an image of a portion other than the cross hatched and oblique hatched portions shown in FIG. Is done.
[0023]
Accordingly, on the display surface of the color display 202, for example, as shown in FIG. 4, the input moving image video signals from the input / output circuits 14a to 14f are displayed on the part of the display surface that is partially cross-hatched, and the display surface is slanted In the hatched portion, a plurality of still images obtained by extracting pixels of a desired frame of the input moving image video signal at a predetermined ratio in advance are displayed. In addition, a signal from the color display 202 is displayed in a portion other than the portion subjected to cross hatching and oblique hatching.
[0024]
Further, in the entire apparatus of the still image file means 1, still images are taken in as follows.
[0025]
That is, a video signal supplied to any of the input / output circuits 14 a to 14 f is subjected to predetermined A / D conversion and supplied to the video bus 11, and the signal on the video bus 11 has a high resolution through the image memory 16 S of the interface circuit 16. It is displayed on a part of the display surface of the color display 202. At this time, a still image for editing described later from the image memory 16M is displayed on the other part of the display surface.
[0026]
In this state, when a predetermined instruction is given with the mouse 204 or the like when a desired image is obtained, this instruction is supplied to the CPU 17 of the still image file means 1 through the CPU 201. Further, in this CPU 17, control data for stopping the supply of signals to the video bus 11 of the input / output circuits 14 a to 14 f is formed. Control data for writing to the memory device 1A is formed.
[0027]
These control data are supplied from the CPU 17 to the connection circuit 18 through the control bus 13, and for the input / output circuits 14a to 14f and the interface circuits 15 and 16, the control data output to the control bus 12 is used as a bus. The video signal is supplied to the video bus 11 via the interface circuit 1B, and is supplied to each circuit while being superimposed on the video signal.
[0028]
That is, in this case, a predetermined horizontal period within the vertical blanking period is assigned to each of the input / output circuits 14a to 14f and the interface circuits 15 and 16, respectively. Then, the control data is supplied to each circuit by outputting the control data at a specific horizontal period timing according to the synchronization signal from the reference signal source 1C in the bus interface circuit 1B.
[0029]
In this way, a still image is captured. After the capture, the input / output circuits 14a to 14f may be stopped 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.
[0030]
The still image captured at this time is expressed by pixels extracted at a predetermined ratio from all pixels together with a full image expressed by data of all pixels of one frame of the input moving image video signal. An index image is formed, and a descriptor including an arbitrary classification code for search and the like is added together with these still images. These two still images and descriptors are written in the memory device 1A in a predetermined format.
[0031]
As a writing format, the descriptor, the full image, and the index image are written in independent areas, and the addresses of the corresponding full image and index image are provided in the descriptor.
[0032]
The index image may be formed by connecting arbitrary hardware to the video bus 11 or may be processed by software by the CPU 17 and the connection circuit 18. Still images captured in the memory device 1A can be transferred and stored in the MO disk drive device 103 or the like, and the MO disk can be taken out and used in other similar devices.
[0033]
Further, the editing of the still image captured in this way is performed as follows.
[0034]
That is, FIG. 5 is a functional block diagram. For example, when an MO disk in which a plurality of still images are written as described above is supplied to the drive device 103, first, a classification code used for a search from a descriptor on the disk, etc. A database is formed [21] at the workstation 2. Images from this database are displayed on the color display 202.
[0035]
On the other hand, when a search [22] is performed with 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 with the searched classification code or the like [11]. The
[0036]
Then, the descriptor is analyzed [12], the addresses of the index image and the full image are stored [13], and the index image is read from the drive device 103 according to the analyzed address [14], and the read index image is read out. Is transferred to the memory device 1A. The index image transferred to the memory device 1A is further transferred to the interface circuit 16.
[0037]
Here, for example, a background image as shown in FIG. 6 is supplied from the CPU 201 to the interface circuit 16 and corresponds to the ranges (1) to (12) hatched in the upper half of the background image. For each address in the memory 16M, the above index images are sequentially written and displayed by the address control [15].
[0038]
It should be noted that 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.
[0039]
On the other hand, ranges (13) to (24) are provided so that the lower half of the background image is also shaded. Then, with the index images displayed in the above ranges (1) to (12), an arbitrary cursor (not shown) is moved into the range of a desired still image with the mouse 204 or the like, and an arbitrary key operation is performed there. Etc., the still image corresponding to the range is discriminated at the workstation 2 [23].
[0040]
Further, according to the determination, the addresses of the desired full image and index image are taken out of the stored [13] addresses, and the full image and index image read out [16] from the drive device 103 are thereby obtained. While being 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).
[0041]
Thereafter, by repeating this operation, desired still image index images are sequentially displayed in the ranges (13) to (24), and the index image and the full image are written in the memory device 1A in that order.
[0042]
In this way, editing is performed, and as a result, packets of still images arranged in the desired transmission order are completed in the memory device 1A. The packet can also be transferred to the drive device 103 and stored on the MO disk.
[0043]
Further, when a still image packet edited as described above is transmitted, the following processing is performed.
[0044]
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 the input / output circuit 14b. Further, the edited still image packet is transmitted in the state stored in the memory device 1A.
[0045]
First, when a sending instruction is issued from the workstation 2, the first still image of the packet is transferred to the input / output circuit 14a and sent out. At the same time, the second still image is transferred to the input / output circuit 14b and displayed on the monitor receiver.
[0046]
Next, when an instruction to send out from the workstation 2 is issued again in this state, the second still picture of the packet is transferred to the input / output circuit 14a and sent out, and the third still picture is sent to the input / output circuit 14b. To be displayed on the monitor receiver.
[0047]
The still images of the packets edited in this way are sent in order. As described above, when a transmission instruction is issued, the first still image to be transmitted is transmitted via the input / output circuit 14a, and the next still image to be transmitted is the input / output circuit. 14b is displayed on a monitor receiver (not shown) separate from the color display 202. The operator confirms the still image to be transmitted next displayed on the monitor receiver, and when it is determined that there is no need to transmit this still image, Transmission can also be stopped.
[0048]
