Abstract
A distance-measuring imaging device includes: a drive controller that outputs a light emission signal and an exposure signal; a light source; a solid-state imager that performs exposure to reflected light; and a TOF calculator that calculates a distance to an object using an imaging signal. The drive controller: cyclically outputs a first exposure signal group in which, before an exposure period of one exposure signal ends, an exposure period of at least one other exposure signal starts; and outputs a second exposure signal group having a dead zone period during which all exposure signals are in a non-exposure period. The TOF calculator calculates a first distance value using a first imaging signal obtained according to the first exposure signal group, calculates a second distance value using a second imaging signal obtained according to the second exposure signal group, and calculates the distance based on the first and second distance values.
