Abstract: In a distance measuring device, a drive controller generates an emission timing signal and an exposure timing signal in accordance with a measurement condition. A light source irradiates light in response to the emission timing signal. A solid-state image sensor has a group of pixels arranged in a matrix pattern and divided into a plurality of regions on a line-by-line basis, and performs an exposure process on a selected one of the regions in response to the exposure timing signal. An imaging signal processor obtains distance information by performing an arithmetic operation on a signal output from the solid-state image sensor. The drive controller generates mutually different measurement conditions to the plurality of the regions of the solid-state image sensor.
