Abstract

PURPOSE:To prevent coloring phenomenon due to a noise component from being generated by deciding the spectral characteristic of a filter so that the color noise components such as smear, etc., of not only a green chrominance signal but a red chrominance signal and a blue chrominance signal can remain and the same containing ratio of noise component can be given in green, red, and blue. CONSTITUTION:The optimum light transmission quantity of green of a cyan and a yellow filter elements is less than that of a green filter element. Then, the chrominance signals of red and blue are obtained by taking a difference between the signal multiplying green output by a prescribed coefficient, not taking the difference among yellow output, cyan output, and the green output as it is. Thereby, the fixed pattern noise of a color which causes the color noise such as a smear component, etc., can be contained by the same quantity in the chrominance signal output of the red, the green, and the blue. Therefore, the smear component. etc., is achromatized on a reproducing picture, then, coloring due to the smear component, etc., can be suppressed.
