ABSTRACT:
A color image recording apparatus for recording a color image using a photosensitive recording medium, wherein the photosensitive recording medium is exposed to at least two light components different in wavelength from each other to superposedly form a latent image thereon. The latent image is developed to provide the color image. In order to separately adjust a hue and a density of the image to be reproduced, a density setting dial and a hue setting dial are provided for setting a desired density and a desired hue. A table memory stores information regarding exposure amounts of each of red, green and blue lights relative to hues in the range selectable by the hue setting dial. The table memory further stores information regarding total exposure amonts relative to the densities in the range selectable by the desnity setting dial. An exposure amount arithmetic circuit determines an exposure amount for each of the light components corresponding to the hue and the density set by those dials in accordance with the information stored in the table memory.
