Abstract
A color imaging method for adjusting color balance of an imaged picture of an object, which object is imaged by a camera head for generating color imaging signals composed of plural color signals. Based on the relative relation between signal levels of the color signals, level balance control data are generated by an information processing device . The level balance control data, generated by the information processing device , is stored in LUTs R, G and B, in association with the signal level of plural color signals in each of plural light exposure volumes adjusted by the light stop of an imaging lens adapted for adjusting the light exposure volume of the camera head or the signal charge accumulating time of a CCD image sensor . Based on the signal levels of the color signals, the level balance control data associated with the color signals are read out from the LUTs R, G and B for controlling the signal levels of the color signals. The color balance can be adjusted even in a grey area intermediate between the black and the white which has not been possible to achieve with the conventional white balance adjustment.
