ABSTRACT:
An image recording apparatus with good color reproduction and easy color adjusting function. An image recording apparatus includes a first color correction unit coupled to receive image signals from the image signal source, a second color correction unit coupled to receive output image signals of the first color correction unit, and a third color correction unit coupled to receive output image signals of the second color correction unit. The image recording apparatus further includes an adjusting device for at least the first color correction unit and the third color correction unit, and an adjustment information entering device. Good color reproduction is realized with color correction and data compression, and is not accompanied by hue change in color perception. Manufacturing variations in the color output unit are corrected by the third color correction unit. Easy setting of the reference for color adjustment independently of the input image signals is also realized by the unit.
