Document Type and Number:
WIPO Patent Application WO/2017/183114
Kind Code:
A1
Abstract:
The present invention is capable of generating a distance image having a higher accuracy.
The present invention is provided with: a light emitting unit (13) that emits light toward a subject (OB) at different emission intensities; a light receiving unit (14), which picks up an image by receiving light including reflected light from the subject (OB), and calculates exposure quantities by each pixel; and a distance calculation unit, which, in a predetermined case, performs replacement between the exposure quantities at a first emission intensity and the exposure quantities at a second light emission intensity, calculates the distance to the subject (OB), and generates a distance image.
