An image pick-up element comprises the following: a first picture element that receives a pair of light beams and outputs a pair of first analog signals; an AD conversion unit that converts the pair of first analog signals into a pair of first digital signals; a digital addition unit that adds together the pair of first digital signals and thereby generates an added digital signal; a first output unit that outputs the pair of first digital signals to the outside; and a second output unit that outputs the added digital signal to the outside. |
