Abstract:
1. A liquid ejection control device adapted to form a single image including a plurality of impressions by ejecting liquid and superposing a plurality of images respectively corresponding to the impressions, the liquid ejection control device comprising: an input unit configured to input image data; an input buffer configured to store first image data inputted by the input unit the first image data including the plurality of impressions; a processing unit configured to produce second image data by subjecting the first image data to processing; an output buffer configured to store the second image data; a liquid ejection unit configured so as to superpose the images respectively corresponding to the plurality of impressions on a target based on the second image data, the output buffer having a storage capacity that is capable of holding image data equivalent to at least two impressions out of the plurality of impressions; and an allocation unit configured to dynamically allocate the storage capacity of the output buffer, when, in the course of switching the image formed by liquid ejection of the liquid ejection unit, formation of the last image prior to the switch ends and results in a blank pass in the output buffer, the allocation unit allocating the blank pass to a buffer located upstream in a data flow direction with respect to the output buffer.
