Imaging device camera system and driving method of the same

Abstract

An imaging device including: an electronic shutter and a pixel array part. The pixel array part has a plurality of pixels with different characteristics of spectral sensitivity arranged in an array and which converts light transmitted through the pixel into an electric signal. The pixel array part has a plurality of color pixels and at least one clear pixel, the plurality of color pixels including (i) a first color filter pixel having a peak of spectral sensitivity characteristics in red, (ii) a second color filter pixel having a peak in blue, and (iii) a third color filter pixel having a peak in green. At least a portion of the plurality of color filter pixels is arranged in an oblique pixel array system and at least one clear pixel having a high transmittance is arranged in the oblique pixel array system at a given position of a given row and a given column with respect to the first color filter pixel, the second color filter pixel, and the third color filter pixel. A first read channel is exclusively coupled to the at least one clear pixel and a second read channel is exclusively coupled to the plurality of color filter pixels; and the electronic shutter is separately driven for the at least one clear pixel and for the plurality of color filter pixels.
