The display control information is stored in the image memory 2 and set in the display control unit 6 via the RAM 9.

The display control unit 6 reads out the image data stored in the image memory 2 in the order in which it is stored at time intervals determined by the set display control information, and transfers it to the image display frame memory 3.

The image data written in the image display frame memory 3 is converted into luminance values of three primary colors for each pixel in an LUT (look-up table) control section 4, and is input to the CRT display 5 and displayed.

[Problem to be solved by the invention]

As explained above, conventional image display devices have the following problems.

■The image display order must be fixed.

In the present invention, an identifier is assigned to each image data to be displayed, and the display control unit 6 holds display control information in which the identifier and display time interval of the image data are set according to the display order, and reads out and displays the information. Take control. Further, the image memory management section 7 holds image memory management information in which the identifier of each image data and the storage address in the image memory 2 are recorded, and reads the image data from the image memory 2 using the identifier.

The display control section 6 reads out the identifier of the image data according to the display order of the display system 91σ information and the set display time interval, and inputs it to the image memory management section 7.

The image memory management section 7 indexes the image memory management information using the input identifier to obtain the storage address in the image memory 2, accesses the image memory 2, reads out the image data, and transfers it to the image display frame memory 3. .

The image data written in the image display frame memory 3 is converted into luminance values of three primary colors for each pixel in an LUT (look-up table) control section 4, and is input to the CRT display 5 and displayed.

The identifier of the image data is expressed by several alphanumeric digits (for example, an alphanumeric character representing the image type and a serial number within the image type),
Display control is performed using this as an intermediary.

With the above configuration, animation display can be performed by setting an arbitrary display order and an arbitrary display time interval.
