ABSTRACT:
An image recording apparatus which applies energy of distributed level to record, on a pixel by pixel basis, image fragments whose density or saturation (tone) corresponds to the necessary energy levels. Image fragments corresponding to an amount of heat of a comparatively high level are contained, on a pixel basis, in image fragments corresponding to an amount of heat of a comparatively low level, whereby record data of the image fragments corresponding to the amount of heat of the comparatively low level are provided. When image fragments corresponding to any of the levels are to be recorded, an amount of heat corresponding to a difference between that particular level and the lowest level is generated.
