Abstract
In the improved shading compensation method applied to thermal recording for recording on a thermal recording material by using a thermal head having a glaze in which heat-generating elements are arranged in one direction, and by relatively moving the glaze and the thermal recording material in a direction perpendicular to the direction in which the heat-generating elements are arranged, with the thermal recording material being kept in contact with the glaze, a plurality of shading compensation tables corresponding to different recording densities are used and the weights of the plurality of shading compensation tables are changed in accordance with the recording densities, to thereby calculate conditions for shading compensation. In thermal recording making use of a thermal head, this shading compensation method is always capable of performing suitable shading compensation irrespective of the recording density and the recording position in the auxiliary scanning direction, to thereby realize a thermal recording apparatus in which high-quality images can be recorded in a consistent manner.
