ABSTRACT:
A solid-state color image pickup device which is capable of simplifying signal processing with respect to picture signals. A color filter mounted on the solid-state image pickup device is composed of first to fourth filter elements E1 to E4. The sum E1+E2 of the signals of color components obtained by adding the color components of the first filter element E1 and the second filter element E2 which are disposed in an odd-numbered row is equal to the sum E3+E4 of the signal of color components obtained by adding the color components of the third filter element E3 and the fourth filter element E4 which are disposed in an even-numbered row. A brightness signal having color components in a predetermined ratio is obtained for each of E1+E2, and E3+E4. A color component signal representing one of the three primary colors (R, G, B) of light is represented by the difference between the color component signals of the first filter element E1 and the second filter element E2, and the difference between the color component signals of the third filter element E3 and the fourth filter element E4. Thus, signals necessary for producing a color image are obtained for each row of light-receiving picture elements.
