Document Type and Number:
Japanese Patent JP2826351
Kind Code:
B2
Abstract:
PURPOSE:To prevent the data quantity of the coordinates for managing image information from increasing more than needed by providing the inside coordinates for managing code information in horizontal and vertical directions further in details with the block coordinates as the origin in accordance with the block coordinates. CONSTITUTION:The block coordinates manage the image information in the horizontal and vertical directions in the prescribed block unit and the inside coordinates manage the code information together with the block coordinates in the horizontal and vertical directions further in details with the block coordinates as the origin. For example, a frame memory writing section 9 writes the image of the block in the display block component transferred from an optical disk reading section 3 and the images of the inside coordinates of the display block component and the codes indicated by the kinds of the codes corresponding to the inside coordinates from the magnetic disk device 8 read by a magnetic disk device reading section 7, respectively into a frame memory 10. Both the images are superposed and displayed on a display 11. The data quantity of the coordinates to manage the image information is prevented from increasing more than needed in this way.
