A color filter, that may be used in conjunction with an image pickup device, includes first, second and third filter domains each of which is transmissive to a different one of three kinds of light each having a different color spectral characteristic. The filter domains are arranged in a matrix consisting of rows and columns. In a predetermined row, the filter domains are arranged repeatedly in an order comprising the first, the second, the third, and a repeat of the third domains. In rows of the matrix adjacent the predetermined row, the filter domains are repeatedly arranged in an order comprising the third, a repeat of the third, the first, and the second domains. This filter has particular utility for use in conjunction with an image pick device having pixels each of which is arranged respectively corresponding to one of the first, the second, and the third filter domains with each pixel accumulating image information. In a preferred embodiment of the filter, the first, second and third filter domains transmit white, yellow and cyan light; green, yellow and cyan light; yellow, white and green light; or white, cyan and green light. Certain of the filter domains may be formed by certain combinations of red, green and blue filter segments. Use of the filter provides reduced folding distortion.
