Patent ID: 7859583

Claim:
A solid state image capture device comprising: a pixel array unit having unit pixels including a photoelectric conversion element disposed in a matrix shape; and analog/digital conversion means for converting an analog pixel signal read from the unit pixel of the pixel array unit into digital data, wherein; the analog/digital conversion means includes; a comparator unit for converting a magnitude of the pixel signal into information in a time axis direction by comparing a reference signal for converting into the digital data with the analog pixel signal; a counter unit for performing a count process during a time period from a start time of a comparison process at the comparator unit to an end time of the comparison process, based on a predetermined clock; a multi-phase clock generate unit for generating multi-phase clocks having a constant phase difference based on the predetermined clock; a latch unit for latching logic states of the multi-phase clocks when the comparison process at the comparator unit is completed; and a decode unit for decoding latch data of the latch unit to obtain a value lower than a count value by the count process.
