ABSTRACT:
A color image processing apparatus including a read-out device for reading a color negative film to produce three color component signals, one component for each of three formation colors. A generation device generates a signal indicating the type or condition of the color negative film read by the read-out device. A gamma correction mechanism corrects the gamma characteristics of the three color component signals and removes an orange mask component corresponding to the indication signal generated by the generating device from the three color component signals. A color masking processing system derives a recording color signal for each formation color from the three color component signals from which the orange mask component has been removed. A color image forming device sequentially forms a color image for each color from each of the recording signals. Also provided is a control mechanism for enabling the read-out device, the gamma correction device, and the color masking processing system a predetermined number of times corresponding to the number of formation colors.
