ABSTRACT:
Picture elements or light-sensitive elements of a solid-state area image sensor have associated color filter elements with three spectral sensitivity characteristics. The human eye requires a first of these colors to have a spectral sensitivity characteristic for producing a high level of visual resolution such as, for example, a green light of a luminance characteristic. The human eye does not require the second and third colors to have such a high resolution of a spectral sensitivity characteristic, such as, for example, a red or blue light, respectively. The green light-sensitive picture elements are arrayed at alternate picture element positions in every horizontal row and at alternate scanning line positions in every vertical column, in order to form a checkerboard pattern. The remaining picture elements are arrayed so that the interspaces between the green light-sensitive picture elements are alternately occupied in the successive scanning lines by the red and blue light sensitive picture elements. Narrow-band signals are provided by the light-sensitive elements for each color and a wide band signal is provided for the color requiring a high resolution. From these various signals, a narrow band signal is synthesized to improve the resolution of the entire picture.
