Abstract
The present disclosure relates to a signal processing device that enables detection of the distance between an imaging device and a subject using an imaging device with high versatility, a signal processing method, and a program. A determination part classifies pixels to a plurality of pixel groups, and determines a pair of a first pixel group and a second pixel group using for detection of distance between the imaging device and the subject from a plurality of pixel groups on the basis of a charge accumulation period for each pixel group of the imaging device in which charge accumulation period is controlled, and a light projection period of pulse light projected toward the subject of the imaging device, for each pixel group. The present disclosure can be applied to, for example, a distance detection device or the like.
