Title:
DISTANCE MEASUREMENT IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/255598
Kind Code:
A1
Abstract:
A distance measurement imaging device (10) comprises: a drive control unit (3) for outputting a light emission control signal for instructing emission of pulse light, and an exposure control signal for instructing exposure by reflected light; an imaging unit (2) which has a plurality of pixels, and which outputs an exposure signal for each pixel exposed at the timing of the exposure control signal; a pixel computation unit (4) for generating a composite signal with respect to the exposure signals through use of a pixel filter for synthesizing the exposure signals of a plurality of adjacent pixels using a weighting coefficient; and a TOF computation unit for generating a distance image on the basis of the composite signal, the pixel computation unit (4) having at least two pixel filters (4A-4E) having mutually different composite magnifications, and selecting either one of the pixel filters.
