Title:
IMAGING DEVICE AND IMAGING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/010355
Kind Code:
A1
Abstract:
An imaging device 500 according to an embodiment is provided with: an emitting unit 10 which emits light; a light-receiving unit 20 which includes a plurality of light-receiving elements 104 for receiving reflected light of the light emitted from the emitting unit 10; and a control unit 30 which controls exposure time for each of the plurality of light-receiving elements 104, or for each of a plurality of unit groups 131 to 135 each having at least two light-receiving elements 104. The plurality of light-receiving elements 104 and the plurality of groups 131 to 135 emit signals corresponding to respective exposure times. The imaging device 500 is further provided with a processing unit 40 which, on the basis of the output signals, generates an image at a distance corresponding to the exposure time, for each of the plurality of light-receiving elements 104 or for each of the plurality of groups 131 to 135. Thus, it is possible to image an object positioned at each distance obtained by dissolving a plurality of distances corresponding to the exposure times of the respective unit groups.
