Abstract: A Time-of-Flight (ToF) sensor includes a plurality of photo-sensitive sensor pixels each including at least two charge storages and a drain terminal. Further, the ToF sensor includes a common charge storage coupled to drain terminals of the plurality of photo-sensitive sensor pixels. For a TOF measurement, the plurality of photo-sensitive sensor pixels are configured to, via the drain terminals, drain part of charge carriers generated during the ToF measurement by incident light caused by one or more objects outside a target measurement range of the ToF sensor. Further, for the ToF measurement, the plurality of photo-sensitive sensor pixels are configured to selectively store another part of the charge carriers in the at least two charge storages of each of the plurality of photo-sensitive sensor pixels. The common charge storage accumulates electrical energy conveyed by currents output by the drain terminals and outputs first data indicative of the accumulated electrical energy.

Abstract: Time-of-flight (TOF) systems and techniques whereby a first exposure obtains pixel measurements for a first subset of pixels of a pixel array, using a first reference signal. For a second exposure, the first subset of the pixels, e.g., every second line of the pixel array, are set to a “hold” state, so that values obtained from the first measurement are maintained. A second exposure using a second reference signal is performed for a second subset of the pixels. The first and second reference signals may have different phase shifts relative to a signal modulating an optical signal being measured. The result is an array of pixels in which the first and second subsets hold results of the first and second exposures, respectively. These pixel values can then be read out all at once, with certain calculations being performed directly as pixel values are read from the pixel array.

Abstract: Embodiments address a concept for exchanging information between time-of-flight ranging devices. For example, a first time-of-flight camera has an illumination unit configured to transmit information to a second time-of-flight camera by modulating a light signal to be emitted in accordance with an information bearing signal. The second time-of-flight camera has a time-of-flight sensor configured to detect the information bearing signal included in the emitted light signal of the first time of flight camera.
