Patent ID: 8754968

Claim:
A solid-state imaging device comprising: a semiconductor substrate having a light receiving surface sectioned for red pixels, green pixels, blue pixels, and white pixels arranged in a matrix with photodiodes formed thereon; color filters formed on the semiconductor substrate in light incident paths to the photodiodes of respective formation regions of the red pixels, the green pixels, and the blue pixels and respectively transmitting light in red, green, and blue wavelength regions; and photochromic films formed on the semiconductor substrate in light incident paths to the photodiodes in formation regions of at least some of the white pixels, and containing a photochromic material having light transmittance varying in response to incident light intensity in a predetermined wavelength region, wherein a half period of the light transmittance of the photochromic films is shorter than one frame as a period in which pixel signals obtained in the pixels are read out with respect to all pixels, and wherein first sets of pixels containing white pixels on which the photochromic films are formed and second sets of pixels containing white pixels on which no photochromic films are formed are alternately arranged on the light receiving surface.
