Abstract:
An image recording method for recording an upper band corresponding to a range recorded by one scanning of a thermal head and a lower band corresponding to a range recorded by a next scanning of the thermal head in superimposed form by a plurality of dots, distributing record data corresponding to the plurality of dots in the superimposed recording range to the upper and lower bands respectively, and activating respective heating elements of the thermal head based on the distributed record data to thereby record an image, comprising:executing a process to successively examine dots in a raster direction corresponding to a scanning direction of the thermal head, adding continuous flags to the dots when record data exist in the dots, and distributing record data for continuous dots supplied with the continuous flags to the upper and lower bands when the record data do not exist therein; andexamining record data for some dots in another raster direction on the basis of record data for continuous dots in the raster direction, which are already subjected to a distributing process, and effecting the same distributing process as a process to distribute the continuous dots in the raster direction set as a reference on record data for the continuous dots in said another raster direction without condition when the examined record data are identical to the record data for the dots in the raster direction set as the reference.
