Patent ID: 8355068

Claim:
A solid-state image sensing device comprising: a pixel array unit in which pixels containing photoelectric conversion devices are arranged in a matrix and a vertical signal line is wired with respect to each pixel column; an analog-digital conversion circuit provided with respect to each pixel column of the pixel array unit and having a comparator using an analog signal supplied from the pixel through the vertical signal line as a comparison target input and a counter that measures a time from start of comparison to completion of the comparison of the comparator; a reference signal generating unit that generates plural reference signals with ramp waveforms; a first switch that, in a thinning readout mode of reading out signals from pixels of a specific group of pixel columns of the pixel array unit to the vertical signal line, shorts the vertical signal line belonging to one pixel column of the specific group of pixel columns and the vertical signal line belonging to another group of pixel columns than the specific group of pixel columns from pixels of which no signals are readout; and a second switch that, in the thinning readout mode, provides the plural reference signals as comparison criterion inputs to the comparator belonging to the one pixel column and the comparator belonging to the another group of pixel columns than the specific group of pixel columns, respectively.
