Patent ID: 8629996

Claim:
A printing apparatus comprising: a movement unit configured to move a carriage incorporating a print head along a carriage shaft arranged in a main scanning direction; a conveyance unit configured to convey a printing medium in a sub-scanning direction perpendicular to the main scanning direction; a storage unit configured to store image data; a reading unit configured to read first image data from the storage unit, wherein the image data stored by the storage unit is divided into a plurality of the first image data in the main scanning direction and the sub-scanning direction; an image processing unit configured to execute predetermined image processing based on the first image data and first image data adjacent to the first image data in the sub-scanning direction; an extraction unit configured to extract, based on information about a deflection of the carriage shaft in the sub-scanning direction, second image data from the first image data for which said image processing unit has executed the image processing; a transfer unit configured to transfer the second image data extracted by said extraction unit to the print head; and a memory configured to hold a table for defining the information about the deflection, wherein the information about the deflection defined in the table is defined independently for each of first image data of a plurality of color components.
