SOLID-STATE IMAGE CAPTURING DEVICE, AND DRIVING METHOD

摘要

While a reset component outputted from a pixel circuit (11) that has not yet received light and a reference signal (RAMP) are compared by a comparator (21), a clock (CK0) is counted down by a counter (22) until the comparator (21) shows a predetermined comparison result, and the value of the counter (22) after the counting down is held in a latch (24). After the value held in the latch (24) is preset in the counter (22), the clock (CK0) is counted up by the counter (22) until the comparator (21) shows a predetermined comparison result while a signal component outputted from the pixel circuit (11) that has received light and the reference signal (RAMP) are compared by the comparator (21), and the value of the counter (22) after the counting up is outputted as a digital value that indicates the amount of light received by the pixel circuit (11).
