Distance measurement system and solid-state imaging sensor used therefor
A distance measurement system includes: a signal generator which generates a light emission signal that instructs light emission and an exposure signal that instructs exposure of reflected light; a first illumination and distance measurement light source which receives the light emission signal and, according to the signal received, performs the light emission for illumination without a purpose of distance measurement and the light emission with the purpose of distance measurement using the reflected light; an imaging device which receives the exposure signal, performs the exposure according to the signal received, and obtains an amount of light exposure of the reflected light; and a calculator which calculates distance information using the amount of light exposure and outputs the distance information, wherein the distance measurement system has operation modes including an illumination mode and a first distance measurement mode.
