Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides an image storage and display device that stores image information in a storage memory and outputs the stored image information as a video signal to a monitor display device for monitoring. It is related to.

Generally, image storage and display devices are improved in usability.

In order to improve processing performance, it is important to be able to write image information efficiently.

Conventionally, when writing image information into the memory of this type of image storage device, an operator specifies a write start point address and a write end point address using a physical address in the storage memory or a two-dimensional coordinate address corresponding to the physical address. In this way, a rectangular write area is set and image information is written in an address area of a memory corresponding to the write area.

However, it is inconvenient for the operator to instruct the setting of the write start point address and the write end point address one by one, and is disadvantageous in terms of improving processing performance.

Normally, when writing an image, the settings for the write start point address and write end point address are limited to specific positions, but even in such cases, when writing an image, you need to perform the operations each time. It was necessary for a person to specify the write start point address and write end point address.

[Summary of the invention]

An object of the present invention is to provide a control memory that stores write area setting information consisting of a combination of a write start point address and a write end point address for each piece of identification information, in order to eliminate the drawbacks of the conventional method in the above-mentioned cases. , the operator can easily set the writing area by simply inputting the identification information from an operating member such as a keyboard, and the operator must instruct the writing start point address and writing end point address one by one. To save time and effort, the present invention will be explained in detail below with reference to the drawings.

11 is a monitor display device; 12 reads image information from the storage memory 5 and outputs a video signal to the monitor display device 11; This is a display control unit that

FIG. 2 shows an example of the structure of the keyboard 6. As shown in FIG.

In the figure, 13 is a display unit, and 14 is a function key for the operator to select various instructions for the image storage/display device. It includes a display key 16 for displaying a start point address and a write end point address on the display unit 13, a registration key 17 for registering a write start point address and a write end point address of a designated write area, and the like.

Further, 18 is a numerical key, and 19 is a mode key for instructing the size of the input image.

The writing area is identified by a pair of mode key 19 and numerical key 18. For example, A4-1 indicates that the original image is a JISA4 size paper, and indicates the first writing area. Each write area is set by registering a write start point address and a write end point address using the registration key 17.

FIG. 3 shows an example of a write area management table 20 that is stored as control information in the control memory 4 of the image storage and display device by performing registration using the registration key 17.

4 and 5 are diagrams showing write areas set in the storage memory 5 by the write area management table 20 shown in FIG. 3. The important point in this embodiment is that the write area setting information 201, 2 consists of a combination of a write start point address and a write end point address as shown in FIG.
02, 203... are each identification information 2OA, 20B, 20
By inputting any of the identification information 2OA, 20B, 20C... into the control memory 4, the corresponding write area setting information 201, 202, 203 is stored in the control memory 4 for each C... 4 and 5 based on the read information.
As shown in the figure, a predetermined address area of the storage memory 5 can be designated and image information can be written to this designated location. In this case, the above information is stored in the control memory 4 using the mode key 19, numerical key 18 and registration key 17.
The above information can be read out by operating the mode key 19, numerical keys 18, and setting key 15.

The operation of the image storage and display device having the above configuration will be explained below.

For example, when the operator selects A4-1 using the mode key 19 and numeric key 18 of the keyboard 6 and presses the setting key 15, the information is transmitted to the main control unit 1 via the keyboard interface unit 7 in the image storage and display device. will be notified. Since the information is an instruction to set a write area, the main control unit 1 selects the write start point address (0, O) corresponding to the identification information A4-1 from the write area management table 20 held in the control memory 4. Write end address (a1
1 in the X address direction from the write start point address (0, 0) to (al, 0).
Instructs writing of image information in continuous memory space for lines. The DMA control unit 4 sequentially writes the image information input from the external bus 8 into the storage memory 5 according to instructions from the main control unit 1, and when writing of data for one line in the specified X address direction is completed, the main The control unit 1 is notified.

The main controller 1 again writes the image information in the continuous memory space for one line in the X direction from the next write start point address (0, 1) to (a,', 1).
instruct. By repeating the above operations until the end of the image information, the image information is written into the writing area corresponding to the identification information A4-1 in FIG. 4. Similarly, identification information A4-2. A4-3. Writing can be performed in the write area indicated by A4-4. Further, the same procedure can be used when the storage memory area is divided as shown by B5-1 to B5-6 in FIG. 5 and JIS85 size images are stored.

〔Effect of the invention〕

As described above, in the image storage display device according to the present invention,
Since the operator can specify the write area in the storage memory simply by inputting the identification information specifying the write area from the keyboard, the usability for the operator can be improved.
