    摘要: An integrated sensor chip comprises at least one pixel. The at least one pixel comprises: one or several integration regions for receiving and storing photogenerated charges; a modulation region that moves the photogenerated charges to be stored in the at least two integration regions; and sense nodes, in which each of the sense nodes is associated with one of the integration regions, into which the photogenerated charges are moved from the integration regions during a readout stage. The chip comprises: at least one function generator for generating a time-varying function that is applied to the integration regions during the readout cycle to move the photogenerated changes to the sense nodes; a counter generates a count during the generation of the time-varying function; and registers, in which each of the registers is associated with one of the sense nodes during read out, for storing digital values; wherein the registers store the count in response to the associated sense node receiving photogenerated charges from the associated integration regions.

    摘要: The sensitivity of a reference pixel array RPA to the reference modulated light MLR is varied for different reference pixels RP of the reference pixel array RPA. In one embodiment the different sensitivities of the reference pixels RP in the RPA is achieved by designing the pixels to have different light sensitivities with respect to each other. In another embodiment, the different sensitivities are achieved by changing optical coupling between the separate reference pixels RP of the reference pixel array RPA to the reference modulated light MLR such as by changing how the different reference pixels RP couple to the aperture LGA of the light guide LG.

    摘要: A modulation technique for 3D time-of-flight (TOF) cameras allows the operation of fully autonomous operated 3D TOF cameras. The method subdivides the exposure time into several sub-exposure intervals, for which the signal control unit adds a preferably pseudo-random common phase delay to the illumination and the sensor.
