发明名称 Image display apparatus that reduces necessary memory capacity for operation
摘要 An image display apparatus for displaying a plurality of objects in a space using a simplified and efficient structure. The apparatus includes a first storing section having areas for scanning lines, and for each scanning line, has an area that stores the object numbers of the objects having that scanning line as the display start scanning line for the objects. In addition, other sections store a display end scanning line and an object information set for each of the objects. A display end determining section reads the object numbers of the current scanning line, and reads the display end scanning line for the objects of the read object numbers to determine whether the current scanning line is the display end scanning line for these objects. For each such object, if the current scanning line is the display end scanning line for an object, then no operation is performed; while if the current scanning line is not the display end scanning line, then the display end determining section adds the read object number to the area in the first storing section that stores the object numbers of the next scanning line. In addition, a display data generating section generates a display image for the current scanning line, and a display displays the display image.
