ABSTRACT:
In an image recording apparatus, a shift amount for shifting a transition position of an output light amount from a light modulator element is obtained with respect to each pixel value-change point in a pixel line in order to correct displacement of writing. In a case where the shift amount excesses a width corresponding to one pixel on a substrate, a pixel value in the pixel line is altered so that the pixel value-change point moves by the number of pixels of an integer part of a value obtained by dividing the shift amount by the width, and the shift amount corresponding to the pixel value-change point is modified to a value equivalent to a decimal part. It is therefore possible to shift the transition position of the output light amount in excess of the distance corresponding to one pixel in recording an image, to record the image with accuracy.
