A solid-state image pickup device includes: comparators; counters; and a control portion for carrying out control in such a way that in a phase of an addition mode, the two comparators and the two counters corresponding to the two pixel columns, respectively, are set as a unit, 1 is added to a second digit of one counter of the two counters when both the comparison results from the two comparators has a first logic, 1 is added to a first digit of the one counter when one of the comparison results from the two comparators has the first logic, and 1 is added to none of the first digit and the second digit of the one counter when both the comparison results from the two comparators has a second logic.

Solid-state image pickup device, signal processing method for the same, and image pickup apparatus using the same

A signal processing device includes a control unit that suspends supplying of a signal to an A/D conversion unit which performs A/D conversion, during an A/D conversion period in which the A/D conversion is performed on the signal that depends on an electric charge read from a pixel; and a maintenance unit that maintains a signal value of the signal in a state where the signal is supplied by the control unit to the A/D conversion unit and that supplies the maintained signal value to the A/D conversion unit in a state where the supplying of the signal to the A/D conversion unit is suspended by the control unit.

Signal processing device and method, imaging device and solid state imaging element

A solid-state image pickup device includes: comparators; counters; and a control portion for carrying out control such that in an addition mode, the two comparators and the two counters corresponding to the two pixel columns, respectively, are set as a unit, and pixel signals are added in a horizontal direction within column processing circuitry. A reduction in power consumption is achieved and the frame rate is enhanced.
