ABSTRACT:
An image recording apparatus for recording an image on an image recording medium includes a digital-to-analog converter for converting digital image data into analog image data, and a multiplier for multiplying the analog image data from the digital-to-analog converter by a signal for correcting for variations in the image recording apparatus. The density of gradations of the image to be recorded is controlled with an output signal from the multiplier. The resolution of the digital-to-analog converter ranges from 8 to 12 bits. The apparatus comprises a multiplying digital-to-analog converter, and the signal for correcting for variations is represented by digital data.
