Zusammenfassung:An imaging apparatus includes a light emitter, a pixel section, and a signal processor which calculates distance information of a subject. The pixel section includes a photoelectric converter, first and second read-out gates, and a plurality of charge accumulators including a first charge accumulator and a second charge accumulator. The first read-out gate is activated in a first period and deactivated in a second period. The second read-out gate is activated in the first period and the second period. The signal processor calculates the distance information based on a total amount of signal charges accumulated in the charge accumulators in the first period and the second period and a difference between an amount of signal charges accumulated in the second charge accumulator in the first period and the second period and an amount of the signal charge accumulated in the first charge accumulator in the first period.
