    • 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.

    • Disclosed is a resolution conversion method, which makes it possible not only to acquire a diagonal edge that is smoothed without causing any unevenness all over the image, but also to stably reproduce a thin line having a thickness corresponding to its original thickness, irrespective of an integer multiple or a non-integer multiple of the magnification factor to be employed for enlarging an original image, when the high-resolution conversion processing is applied to a binary image represented in the dot-matrix format. An operation for integrating the interpolation value with respect to the area of the input pixel is implemented after the output pixel area is shifted in a horizontal direction and/or a vertical direction so as to make the output pixel area depart from a center of the interpolation area, when the output pixel area is included in a single interpolation area in the horizontal direction and/or a vertical direction.
