发明名称 IMAGE RECORDING APPARATUS AND CONTROL METHOD THEREFOR
摘要 An image recording apparatus according to this invention analyzes image data to be printed, and generates sequence information for defining the moving range of each scanning motion of a recording head and the conveyance amount of a recording medium. The apparatus divides a recording area defined by the generated sequence information into areas so that the processing amounts of a plurality of processing units capable of parallelly executing processes are equal to each other, distributes data of the divided areas to the processing units, and causes each of the processing units to generate recording image data. The apparatus performs recording by controlling driving and a scanning motion of the recording head and conveyance of the recording medium based on the recording image data obtained by the processing units.

主权项 1. An image recording apparatus for printing an image on a recording medium by performing a scanning motion of a recording head in which a plurality of recording devices are arrayed, and relatively conveying the recording medium in accordance with the scanning motion in a direction intersecting a direction of the scanning motion, the apparatus comprising: a generation unit configured to generate, based on image data to be printed, sequence information indicating a moving range of each scanning motion of the recording head for each of a plurality of areas on the recording medium, whose positions in the intersecting direction are different; a plurality of processing units configured to parallelly execute processes of generating recording image data to be used for driving the recording head; a divided area determination unit configured to determine, based on the sequence information generated by the generation unit, for a plurality of divided areas obtained by dividing a recording area on the recording medium on which the recording head performs recording, divided areas respectively corresponding to the plurality of processing units so that the plurality of processing units perform the processes corresponding to the separate divided areas; a distribution unit configured to cause each of the plurality of processing units to generate recording image data by transmitting, to the plurality of processing units, data corresponding to the divided areas determined by the divided area determination unit in the image data to be printed; and a recording unit configured to perform recording by controlling driving and a scanning motion of the recording head and conveyance of the recording medium based on the recording image data obtained by the plurality of processing units.
