Abstract
An image data processor for processing image information representative of images, into bit map data to be used by an output device to output the images with a predetermined output resolution, and storing the bit map data into an empty area of a memory for subsequent use by the output device. The processor includes a comparator for determining whether a memory capacity required for storing first bit map data for outputting the images with a nominal output resolution is larger than a memory capacity of the empty area of the memory, and a device responsive to the comparator means, for modifying the first bit map data into second bit map data which is adapted to output the images with a reduced output resolution lower than the nominal output resolution, such that a memory capacity for storing the second bit map data does not exceed the memory capacity of the empty area of the memory, if the memory capacity required for storing the first bit map data is larger than the memory capacity of the empty area of the memory. The second bit map data is stored into the empty area of the memory.
