<p><P>PROBLEM TO BE SOLVED: To solve the problem of a color filter array being mounted on a solid state image sensor that resolution or sensitivity deteriorates when a filter transmitting infrared rays is arranged. <P>SOLUTION: An R filter included in a Bayer pattern color filter array is replaced partially by an IR filter transmitting infrared rays selectively. The IR filter and the R filter are arranged in check pattern in the color filter array. Since two G filters are arranged in each pixel block of 2×2 pixels, deterioration of resolution can be suppressed. Furthermore, deterioration of sensitivity to visible light can be suppressed because the one IR filter exists in two pixel blocks. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
