Solid-state imaging device and electronic equipment

摘要

A solid-state imaging device includes: a semiconductor substrate having a light receiving surface sectioned for red, green, blue, 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 the respective formation regions of the red, green, and blue pixels and respectively transmitting lights in red, green, and blue wavelength regions; and photochromic films formed on the semiconductor substrate in the light incident path to the photodiodes in the 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.
