Solid state image capturing apparatus and camera apparatus

摘要

A solid state image capturing apparatus is disclosed. A pixel array section has unit pixels containing photoelectric conversion elements, the unit pixels being two-dimensionally arranged in a matrix, and column signal wires correspondingly to columns of the matrix of the unit pixels. A line scanning section selectively controls lines of the matrix of the unit pixels of the pixel array section. An analog-to-digital conversion section converts an analog signal outputted from unit pixels of a line of the matrix of the unit pixels selected by the line scanning section through a corresponding column signal line to a digital signal. A conversion clock supply section selectively generates a conversion clock having a first clock period or a second clock period. An addition section adds unit pixel digital signals converted in the analog-to-digital conversion section by the conversion clocks having the first clock period and the second clock period, respectively.
