An image generating apparatus comprises an image data storage unit configured to store an original image data therein, and an image data buffering unit that allows data to be read out therefrom at a higher speed than the image data storage unit. A display times counting unit divides a whole of the original image data into a plurality of blocks and counts the number of times each of the blocks has been referenced or utilized for the generation of the image data to be displayed, as the number of display times. A priority order setting unit sets a priority order on a block-by-block basis based on the number of display times thus counted. A buffering control unit performs a control such that image data in a block which is given a higher priority order is stored in the image data buffering unit more preferentially.
