Patent ID: 7654627

Claim:
An inkjet recording apparatus that records data on a recording medium based on recording data, comprising: a plurality of line heads each of which has a plurality of recording elements across a whole recording area on the recording medium and drives said plurality of recording elements in each line for recording the recording data; a thinning pattern generation unit that, for each line head, generates one line of thinning pattern for each line of the recording data for determining whether or not each bit of the recording data is to be recorded, such that the line of thinning pattern for the same line head varies from line to line; a processing unit for varying the one line of thinning pattern for the recording data from line head to line head; and a thinning processing unit that, for each line head, generates thinned-out recording data generated by thinning out the recording data by applying the thinning pattern to the recording data; wherein each line head is driven by the thinned-out recording data generated by said thinning processing unit.
