ABSTRACT:
An inkjet recording apparatus that records data on a recording medium based on recording data and using a plurality of line heads includes a thinning pattern generation unit (12) that generates one line of thinning pattern for determining whether or not each bit of the recording data is to be recorded; a shift processing unit (13) that shifts the thinning pattern a predetermined number of bits; and a thinning processing unit (14) that, for each line head, generates thinned-out recording data generated by thinning out the recording data by applying the thinning pattern, shifted by the predetermined number of bits, to the recording data, wherein each line head is driven by the thinned-out recording data generated by the thinning processing unit (14). The shift processing unit (13) shifts the thinning pattern, generated by the thinning pattern generation processing unit (12), the predetermined number of bits to prevent the same thinning pattern from being used for the adjacent lines in the feed direction.
