Abstract
A Time-of-Flight (ToF) ranging device and a ToF ranging method are provided. The ToF ranging device includes a signal processor, a light emitter, and a light sensor. The light emitter sequentially emits a plurality of intense pulsed lights to a sensing target. The light sensor sequentially receives the plurality of intense pulsed lights reflected by the sensing target to correspondingly output a plurality of pixel voltage signals. The signal processor generates a plurality of read-out voltage signals according to the plurality of pixel voltage signals. The signal processor compares the plurality of read-out voltage signals with a plurality of count signals to obtain a plurality of count values. The signal processor calculates an average value of the plurality of count values and determines a distance between the ToF ranging device and the sensing target according to the average value.
