Patent ID: 8199229

Claim:
A color filter allowing a light signal to pass through by each pixel and be incident on an imaging device, the light signal being inputted through a lens and including one of plural different spectral components, wherein: the plural different spectral components include: a first spectral component which has a widest frequency bandwidth among the plural different spectral components, a second spectral component corresponding to a predetermined frequency band close to a frequency that causes no chromatic aberration of the lens, and a third spectral component expressed in terms of a linear sum of a value resulting from multiplying the first spectral component by a first weighting factor and a value resulting from multiplying the second spectral component by a second weighting factor, and wherein the plural different spectral components are of five types of spectral components including the first spectral component, the second spectral component and the third spectral component, and pixels corresponding to the first spectral component and the third spectral component and pixels corresponding to a fourth spectral component and a fifth spectral component are respectively arranged adjacent to a pixel corresponding to the second spectral component in one of a 0-degree direction, a 45-degree direction, a 90-degree direction and a 135-degree direction assuming that one array direction of a plane, on which the pixels are arrayed, is set as the 0-degree direction, the pixels corresponding to the first spectral component and the third spectral component are arrayed in a direction orthogonal to the pixel corresponding to the second spectral component, and the pixels corresponding to the fourth spectral component and the fifth spectral component are arrayed in the 45 degree or the 135 degree direction from the pixel corresponding to the second spectral component.
