Abstract
A time-of-flight camera includes a light generator that generates an emitted light wave, a light sensor that receives a reflected light wave that corresponds to the emitted light wave reflected from an object, and distance determination circuitry. The distance determination circuitry determines response signals based on the reflected light wave, calculates signs corresponding to differences between pairs of the response signals, determines a phase region based on the signs, and determines a distance between the time-of-flight camera and the object based on a ratio of the differences.
