摘要： If a non-edge part of an image is thinned at a constant thinning ratio regardless of an image size (a character size or a line image width), a reduction in image density in the non-edge part becomes more conspicuous with increasing image size, which can lead to a reduction in image quality. In view of the above, the thinning ratio at which to thin data in the non-edge part of the image is determined depending on the image size. The thinning ratio is set to be smaller for images with sizes greater than or equal to a predetermined value than for images with sizes smaller than the predetermined value such that a high-quality image with sufficiently high density in its non-edge part is obtained regardless of the image size.

摘要： A recording apparatus for discharging ink from a recording head arraying a plurality of nozzles to execute recording of an image includes a drive unit configured to form a group with a defined number of nozzles so as to include an adjacent nozzle in a different block and to execute time-division driving of the block according to a driving order corresponding to a recording mode, and a recording control unit configured to execute scan recording to a recording medium in a first recording mode or a second recording mode. Each pass of scan recording in the second recording mode is executed using nozzles smaller in number than a number of nozzles used to execute each pass of scan recording in the first recording mode. The recording apparatus further includes a driving control unit configured to control the drive unit wherein a drive interval of an adjacent nozzle in the same group corresponding to the first recording mode is larger than a drive interval of an adjacent nozzle in the same group corresponding to the second recording mode.
