Color image processing method and apparatus |
摘要 |
In a first signal suppressing process, in cases where a signal level of a certain color signal among color signals obtained from an image sensing operation is higher than a predetermined signal level, the certain color signal is suppressed. An image sensing operation with a comparatively large exposure quantity and an image sensing operation with a comparatively small exposure quantity are performed alternately. It is detected that suppression of a certain color signal is performed in the first signal suppressing process when the image sensing operation with a comparatively large exposure quantity is performed. A calculation is made to find composition ratios of the color signals, which are obtained from the image sensing operation with a comparatively small exposure quantity. A second signal suppressing process is performed for suppressing at least one color signal other than the certain color signal such that the composition ratios become identical with the calculated composition ratios. |
