For a single exposure of a light capturing element of a time-of-flight sensor, a method for time-of-flight sensing includes illuminating a scene at least once with a first modulated light signal and illuminating the scene at least once with a second modulated light signal. The method also includes driving the light capturing element at least once based on a first reference signal portion for measuring reflections of the first modulated light signal from the scene, and driving the light capturing element at least once based on a second reference signal portion for measuring reflections of the second modulated light signal from the scene. The first modulated light signal and the second modulated light signal each exhibit a first duty cycle. The first reference signal portion and the second reference signal portion each exhibit a second duty cycle. The first duty cycle is lower than the second duty cycle.
A method for time-of-flight sensing, the method comprising for a single exposure of a light capturing element of a time-of-flight sensor:
A time-of-flight sensor comprising an illumination element, a light capturing element and driver circuitry, wherein for a single exposure of the light capturing element:
