ABSTRACT:
In a method for correcting a luminance signal of a single-plate type color camera which is arranged to read out signals for three primary colors, red (R), green (G) and blue (B), by using a solid-state image sensor and to separate and take out the luminance signal and color difference signals, a correction circuit is used for correcting the luminance signal with a correction signal which is formed from the color difference signals, and the correction signal is formed by selecting one of the color difference signals which has the largest value among the color difference signals.
