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.

Claim (Index 9):
A solid-state imaging device used in a distance-measuring imaging device that measures a distance to an object by applying pulse light to and receiving reflected light from the object,\n wherein the distance-measuring imaging device includes: a controller that outputs a light emission signal and an exposure signal; a light source that applies the pulse light at timing indicated by the light emission signal; and a calculator that calculates the distance to the object, wherein the controller: cyclically outputs a first exposure signal group that is made up of a plurality of exposure signals different from each other in delay time with respect to the light emission signal and 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 that is made up of one or more exposure signals different from each other in delay time with respect to the light emission signal and that has a dead zone period during which all of the one or more exposure signals are in a non-exposure period, the 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 distance value and the second distance value, and the solid-state imaging device: performs exposure to the reflected light at timing indicated by each exposure signal in the first exposure signal group, and outputs the first imaging signal indicating an exposure amount corresponding to the first exposure signal group to the calculator; and performs exposure to the reflected light at timing indicated by each exposure signal in the second exposure signal group, and outputs the second imaging signal indicating an exposure amount corresponding to the second exposure signal group to the calculator.
