Title:
撮像装置、それに用いられる固体撮像素子及び撮像方法
Document Type and Number:
Japanese Patent JP7426339
Kind Code:
B2
Abstract:
An imaging device includes: a light source emitting light based on a first pulse; a solid-state imaging element including pixel units and exposing the light based on a second pulse; and a signal processor. Each pixel unit includes a photoelectric converter and charge accumulating units, and generates first to third signal charges by first to third exposure processes in this order to be accumulated in the charge accumulating units. Each of the first and third exposure processes is based on the second pulse delayed from the first pulse by a first period, and the second exposure process is based on the second pulse delayed from the first pulse by a second period. A total period of the first and third exposure processes is equal to that of the second exposure process. The signal processor calculates a distance signal for each pixel unit by using the first to third signal charges.
