Abstract
A solid-state color imaging apparatus having a plurality of picture elements for converting incident light to signal charges with the picture elements being arrayed regularly in both a horizontal direction and a vertical direction to form horizontal rows and vertical columns. First color filters are on the picture elements in odd numbered rows for providing modulation characteristics of color components and causing the picture elements in the odd numbered rows to generate a first color difference signal. Second color filters are on the picture elements in even numbered rows for providing modulation characteristics of color components and causing the picture elements in the even numbered rows to generate a second color difference signal. The first and second color difference signals are substantially zero when achromatic light is incident upon the picture elements or is picked up at a reference color temperature.
