Abstract

PURPOSE:To make it possible to display the whole of a graphic with a large size such as a long size drawing without increasing its reduction ratio by providing this processor with a means for transferring respective image data divided into plural parts to respective display memories and a means for displaying the contents of respective display memories in respective display devices. CONSTITUTION:The image data of a long size drawing recorded in an optical disk is developed in a picture memory 50 through a picture processing LSI 51. The image data of the concerned stored in the memory 50 are divided into four parts through the LSI 51 and respective divided data are transferred to respective display memoris 42a to 42d. Then the contents of respective memories 42a to 42d are displayed on respective display devices 24a to 24d. Since the whole image data of the long size drawing or the like are divided into plural parts and the divided data are displayed on plural display devices 24a to 24d, the large size drawing the whole of which can not be simultaneously displayed on one display device without increasing its reduction ratio can be simultaneously displayed on plural display devices.

Means for dividing the image data in the image data into a plurality of pieces by using an image processing LSI, reducing the image data, a means for transferring each of the divided image data pieces to each display memory, and displaying the contents of each display memory on each display device. And means.

According to a second aspect of the invention, means for expanding the image data of the drawing recorded on the optical disk into the image memory through the image processing LSI, and the image data in the image memory is divided into a plurality of pieces using the image processing LSI. And means for reducing the size of the image data, a means for transferring the image data divided into a plurality of pieces to each display memory, and a means for displaying the contents of each display memory on each display device.

According to a third aspect of the invention, means for expanding the image data of the drawing recorded on the recording medium into the image memory through the image processing LSI, and a plurality of image data in the image memory by using the image processing LSI. It is provided with a unit for dividing and reducing, a unit for transferring each image data divided into a plurality to each display memory, and a unit for displaying the contents of each display memory on each display device arranged continuously and integrally.

[0010]

According to the present invention, image data such as a long drawing recorded on a recording medium is developed in an image memory through an image processing LSI, and the image data in the image memory is divided into a plurality of pieces using the image processing LSI. . Then, each image data divided into a plurality of pieces is transferred to each display memory, and the contents of each display memory are displayed on each display device.
