Abstract
An image detection apparatus includes a color filter for receiving light and for passing luminance components and color components of the light. The color filter has first and second lines which filter elements for luminance components disposed in each line and offset from filter elements for luminance components in an adjacent line, the first line including filter elements for two color components, and the second line including filter elements for a single color component. An image sensor unit receives the luminance and color components passed by the color filter, and outputs signals corresponding to the respective luminance components and color components. A signal processing unit receives the signal output by the image sensor unit, and generates a color difference signal from the received signals.
