Abstract
A time-of-flight (TOF) sensing system may include an illumination module and a sensor module. The sensor module may include an array of sensor pixels, each sensor pixel configured to perform multiple measurements to generate corresponding pixel data for a TOF sensing operation. Signal processing circuitry may generate phase data based on the pixel data. Phase denoise circuitry in the signal processing circuitry may perform different types of filtering operations on the phase data such as perform two bilateral filters of varying strengths. The lower-fidelity denoised phase data may be used for depth disambiguation, while the higher-fidelity denoised phase data may be used for depth calculation. If desired, the phase denoise circuitry may perform averaging operations for one or both of these filtering operations using a Cartesian coordinate representation and efficiently using piecewise linear trigonometric approximations.
