Patent ID: 8605175

Claim:
A solid-state image capturing device comprising: a semiconductor substrate having a photosensitive surface including a matrix of pixels including respective photoelectric converters; and a photochromic film disposed in a light path through which light is applied to each of the photoelectric converters, each pixel generating a corresponding pixel signal based on the light applied to the photoelectric converter, wherein, the photochromic film is made of a photochromic material having a light transmittance that varies depending on an intensity of applied light in a predetermined wavelength range, the light transmittance has a half-value period shorter than a duration of one frame corresponding to a period of time during which the pixel signals generated by the pixels are read from all of the pixels, and the photochromic film has a photoelectric effect and the solid-state image capturing device further comprises a light amount measuring unit that measures an amount of light absorbed by the photochromic film.
