SOLID-STATE IMAGE CAPTURING DEVICE AND ELECTRONIC DEVICE
First Claim
1. A solid-state image capturing device comprising:
- a semiconductor substrate having a photosensitive surface including a matrix of pixels as respective photoelectric converters; and
a photochromic film disposed in a light path through which light is applied to each of said photoelectric converters, said photochromic film being made of a photochromic material having a light transmittance variable depending on the intensity of applied light in a predetermined wavelength range;
wherein said light transmittance has a half-value period shorter than one frame during which pixel signals generated by said pixels are read from all said pixels.
