Abstract:
1. A solid state imaging device comprising: a pixel array part which has a plurality of pixels which are arranged two-dimensionally and each of which includes a photoelectric conversion element, a plurality of vertical signal lines which transmit a signal from each of the plurality of pixels and a color filter which has a predetermined color coding at the plurality of pixels; a column signal processing circuit part which has a plurality of analog amplifiers which receive the signal from each of the plurality of pixels transmitted through the plurality of vertical signal lines and a plurality of feedback capacitances which are adjustably connected in parallel to the plurality of analog amplifiers; a first control part which performs control in which a certain number of pixels in the same color in row wise and column wise directions is a unit pixel block, and in reading signals of the pixels in the same color in a single row in the unit pixel block, the signals of the pixels in the same color are stored in a first feedback capacitance of a single column in the column signal processing circuit part; a second control part which performs control in which in reading signals of the pixels in the same color at a row different from the single row in the unit pixel block, the signals stored in the first feedback capacitance are pre-charged in a second feedback capacitance at a column different from the single column in the column signal processing circuit part; and a third control part which performs control in which the signals of the pixels in the same color at the different row are stored in the second feedback capacitance after pre-charged.
