Solid-state imaging device that adjusts frequency of a clock to change a gain of a counter to a determined gain |
摘要 |
A solid-state imaging device comprises a pixel array; a reference signal generation unit operable to generate a reference signal that changes monotonically for a predetermined period in a horizontal period; a comparator operable to compare the level of a pixel signal with the level of a reference signal; a counter operable to count input clock pulses; a memory operable to store the number of counts counted by the counter as a digital value; and a timing control unit operable to generate a clock that is to be input into the counter, and change frequency of the clock that is to be input into the counter based on external input data.
