Abstract
An image sensor includes: first pixels, each of which receives a pair of light fluxes and outputs a pair of first analog signals; an A/D conversion unit that converts each of pairs of first analog signals to a pair of first digital signals; a digital adder unit that generates digital sum signals each by adding together the pair of first digital signals among pairs of first digital signals; a first output unit that outputs pairs of first digital signals to an external recipient; and a second output unit that outputs the digital sum signals to an external recipient.
Claims15
An image sensor comprising:
- a first photoelectric converter and a second photoelectric converter that convert light and generate charge;
- a first signal line that outputs a signal based on the charge generated by the first photoelectric converter;
- a second signal line that outputs a signal based on the charge generated by the second photoelectric converter;
- an A/D converter that converts an analog signal based on the charge generated by the first photoelectric converter to a first digital signal and that converts an analog signal based on the charge generated by the second photoelectric converter to a second digital signal;
- and
- an adder that adds together the first digital signal and the second digital signal.
