Abstract
In an image recording apparatus provided with a recording head and a conveyor for relatively moving the recording head and an image recording medium, an image composed of a large number of pixels is recorded by plural recording elements of the recording head on the image recording medium relatively moved by the conveyor. Each recording element of the recording head is controlled to conduct turning on or off plural times (N times) so that one pixel is recorded by plural recording periods of each recording element, and a time length T(m) of each recording period is not increased monotonously or is not decreased monotonously with respect to recording sequential order “m” of each recording period in recording of each pixel, wherein “m” is an integer not less than 0 and not more than N−1. The time length of each recording period is obtained by adding one or two coefficients to a binary-weighted value.
