Abstract
The invention provides a technique of making color adjustment for a great number of colors among different imaging apparatus. In the process of making color adjustment among a plurality of cameras, a color correction processing unit disposed in a CCU of each camera detects data associated with lightness, hue, and saturation for a plurality of specified colors. The detected data is transmitted as color data to a CPU. According to the color data supplied from each CCU, the CPU divides the color space into a plurality of areas, and calculates setting data which is required by the color correction processing unit to correct the lightness, hue, and saturation. The resultant setting data is transmitted to the color correction processing unit. In actual use in a normal operation mode, the color correction processing unit corrects the lightness, hue, and saturation according to the procedure determined for each area in accordance with the setting data.
