Abstract
Abstract A chromatic image recording apparatus comprises a gradation control member, an image reading member, a hue characteristics calculating member and a hue characteristics control member. In the chromatic image recording apparatus, the optimum exposing conditions of an original having a deviated color balance can be easily established. The output chromatic image of desired quality can be obtained, irrespective of any hue characteristics of the chromatic image on the original. When a brightness characteristics calculating member and a brightness characteristics control member replace the hue characteristics calculating member and the hue characteristics control member, the output chromatic image of desired quality can be obtained, irrespective of any brightness characteristics of the chromatic image on the original. When the chromatic image recording apparatus additionally comprises an auxiliary exposure member and an auxiliary exposure control member, the output chromatic image can be reproduced with an improved color gradation.
