DISTANCE MEASURING DEVICE

摘要

In a distance measuring device, a drive controller (103) generates an emission timing signal (SG1) and an exposure timing signal (SG2) in accordance with a measurement condition. A light source (104) irradiates light in response to the emission timing signal (SG1). A solid-state image sensor (109) 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 (SG2). An imaging signal processor (101) obtains distance information by performing an arithmetic operation on a signal output from the solid-state image sensor (109). The drive controller (103) generates mutually different measurement conditions to the plurality of the regions of the solid-state image sensor (109).
