Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a device for servicing still image information.

[0002]

2. Description of the Related Art FIG. 2 is a block diagram showing an example of a conventional still image information service apparatus. In the figure, 1
Is a host computer of the device, 2 is a still image video information conversion device, 3 is a still image holding device, and 9, 10 and 11 are still image information data, a command command and a completion response, respectively. Reference numerals 4 and 5 indicate a still image holding command command, a still image holding completion response, and 8 indicates still image data.

Next, the operation will be described. The still image information data 9 created by the host computer 1 is sent to the still image video information conversion device (drawing device) 2. The still image video information conversion device 2 creates a still image based on the drawing command command 10. The still image video information conversion device 2 that has completed the generation of the still image sends the drawing completion response 11 to the host computer 1
Send to.

Next, the host computer 1 commands the still image video information conversion device 2 to send the data of the created still image to the still image holding device 3. Upon receiving this command, the still image / video information conversion device 2 sends the still image data to the still image holding device 3. The still image holding device 3 stores the sent still image data in a predetermined area, and when the storage is completed, sends a still image holding completion response 5 to the host computer 1.

[0005]

In this conventional still image information service apparatus, since the host computer 1 intervenes in all steps of processing and operation, when the host computer 1 interfaces with another computer, etc. There is a problem that the load is concentrated on the host computer 1.

The present invention has been made to solve this problem and reduces the load on the host computer.
An object of the present invention is to provide a still image information service device capable of shortening the time required from the drawing process to the storing process.

[0007]

In order to achieve the above-mentioned object, the present invention provides a still image information service apparatus including a host computer, a still image video information conversion apparatus, and a still image holding apparatus,

The host computer sends a plurality of types of commands to the still image holding apparatus and receives a completion response only from the still image holding apparatus, and the still image holding apparatus selects one of the plurality of types of commands. The command whose destination is the above-mentioned still image video information conversion device is transferred to the still image video information conversion device.

[0009]

According to the present invention, after the host computer sends a command, the still image / video information is generated until the still image / video information forming device completes the creation of the still image and the storage of the created still image in the still image holding device. It is exchanged between the digitizing device and the still image holding device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 4 is a host computer 1.
Is a command (still image holding command command) to be sent to the still image holding device 3, and there are, for example, 12 types, and four types of commands 6 are sent to the still image video information processing device 2 and out of the 12 types The storage command command is sent to both the still image holding device 3 and the still image video information conversion device.
This storage command command includes still image information.
Reference numeral 5 is a still image holding completion response, and 7 is a drawing response.

Each command is composed of, for example, 12 bits, and if a certain bit is "1", the command is addressed to the still image holding device 3, and if it is "0", the command is converted to still image video information. It is supposed to be addressed to the device 2. However, only the storage command command is applied to the still image video information conversion device 2
It will also be sent to.

The still image holding device 3 which has received the storage command command from the host computer 1 refers to necessary data (storage area address) of the data included in the storage command command, and then the still image video information conversion device 2 Transfer to. Upon receiving the storage command command, the still image / video information processing device 2 creates a still image based on the still image information data included in the storage command command, and sends the created still image data to the still image holding device 3. . The still image holding device 3 writes this data in the frame memory and holds it in the storage area.

As described above, in the present embodiment, the host computer 1 does not interact with both the still image / video information conversion device 2 and the still image storage device 3, and the still image storage device 3 does not. Since it interacts with
The load on the host computer 1 is reduced. The steps from the drawing process to the storing process and the display on the display device are processed and executed in the still image holding device 3.

The clearing of the stored still image and the display on the display device are processed and executed in the still image holding device 3.

[0016]

As described above, according to the present invention, the still image holding device is positioned between the host computer and the still image video information processing device, so that the host computer intervenes in the steps from the drawing process to the storing process. Since the opportunity to do so is significantly reduced, the host computer can easily configure a network and the like with other systems.
