1. A recording apparatus comprising:
a recording head including a recording element row where a plurality of recording elements configured to generate energy to discharge ink are arrayed in a predetermined direction; a scanning unit configured to execute
a first scan of the recording head over a unit region on a recording medium, K (K≧1) times in a first direction following an intersecting direction intersecting the predetermined direction, anda second scan of the recording head over the unit region, L (L≧1) times in a second direction opposite to the first direction; a generating unit configured to generate recording data stipulating discharge or non-discharge of ink, as to each of a plurality of pixel regions within the unit region, in each of K+L scans by the scanning unit, based on image data that corresponds to an image to be recorded in the unit region and stipulates a plurality of combinations of number of times of discharge of ink to each of the plurality of pixel regions, and K+L mask patterns corresponding to the K+L scans by the scanning unit; a time-division driving unit configured to
perform time-division driving of a plurality of recording elements corresponding to the unit region following first driving order in the K first scans, andperform time-division driving of a plurality of recording elements corresponding to the unit region following a second driving order, that is different from an opposite order to the first driving order, in the L second scans; and a control unit configured to effect control to discharge ink to the unit region by driving the plurality of recording elements by the time-division driving unit, based on the recording data generated by the generating unit, in the K+L scans by the scanning unit, wherein, disposed in the K+L mask patterns are at least
first recording permitted pixels regarding which discharge of ink is permitted in a case where the number of times of discharge of ink indicated by the image data is N (N≧1) times or more,second recording permitted pixels regarding which discharge of ink is permitted in a case where the number of times of discharge of ink indicated by the image data is M (M>N) times or more, but not permitted to discharge ink if less than M times, andrecording non-permitted pixels not permitted to discharge ink regardless of the number of times of discharge of ink indicated by the image data, and wherein, of the pixel regions corresponding to the first recording permitted pixels in the L mask patterns corresponding to the L times of second scans, the number of pixels adjacent on both sides in the intersecting direction to pixel regions that correspond to the first recording permitted pixels in the K mask patterns corresponding to the K times of first scans, is larger than the number of pixels not adjacent on both sides in the intersecting direction to pixel regions that correspond to the first recording permitted pixels in the K mask patterns corresponding to the K times of first scans. |
