Title: DISTANCE MEASURING DEVICE
Abstract:
In a distance measuring device (100) which uses a round-trip time of light to measure a distance to an object, a solid-state image capturing element (102) has a plurality of pixel groups the exposure of which can be controlled independently, and reflected light from the object, originating from pulsed light radiated by a light source (115), is received using a different exposure time for each pixel group. A light emission and exposure control unit (101) implements periodic intermittent exposure control for obtaining a plurality of types of pixel signals with different exposure times, corresponding to a time difference between the radiated light and the reflected light for each pixel group in the solid-state image capturing element (102), and a signal processing unit (103) obtains distance information to the object on the basis of pixel signals of adjacent pixels in pixel groups in the solid-state image capturing element (102) having different exposure times.
