Title:
DISTANCE IMAGE CAPTURING DEVICE AND DISTANCE IMAGE CAPTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/158536
Kind Code:
A1
Abstract:
The present invention comprises: a light receiving unit including a photoelectric conversion element for generating charge due to incident light, a plurality of pixel circuits comprising N (N≧3) charge storages and transfer transistors for storing charge at a frame period, and a pixel drive circuit for causing charge to be distributed and stored by the transfer transistor in the charge storages at a storage timing synchronized with an optical pulse; a light source unit for emitting the optical pulse; a distance image processing unit for determining a distance to a subject on the basis of the amount of charge stored; and a measuring control unit which, on the basis of the amount of charge stored in the charge storages, the distance, and the intensity of incident light, determines a number of decimation processes in which no storage is performed. The measuring control unit controls charge storage on the basis of the number of decimation processes set in a measurement zone corresponding to the distance from the light receiving unit.
