ABSTRACT:
A color image recording apparatus to record a color image by printing coloring agents of different colors comprises: recording heads such as ink jet heads to record coloring agents such as inks of different colors; temperature sensors, provided for the recording heads, for detecting temperatures of the heads; a color correction circuit to perform the color correction of an input color image signal; a drive circuit to drive the heads in response to correction outputs of the color correcting circuit; and a change control circuit to change correction characteristics of the color correcting circuit on the basis of detection outputs of the temperature sensors. The color processes are changed in accordance with a change in temperature of each head. With this apparatus, even if the temperatures of the respective color heads differ, stable color reproducibility can be maintained.
