    摘要: An imaging system includes first and second imaging arrays separated by a fixed distance, first and second drivers, and a modulated light source. The first imaging array includes a plurality of phase-responsive pixels distributed among a plurality of intensity-responsive pixels; the modulated light source is configured to emit modulated light in a field of view of the first imaging array. The first driver is configured to modulate the light output from the modulated light source and synchronously control charge collection from the phase-responsive pixels. The second driver is configured to recognize positional disparity between the intensity-responsive pixels of the first imaging array and corresponding intensity-responsive pixels of the second imaging array.

    摘要: A depth-sensing method for a time-of-flight depth camera includes irradiating a subject with pulsed light of spatially alternating bright and dark features, and receiving the pulsed light reflected back from the subject onto an array of pixels. At each pixel of the array, a signal is presented that depends on distance from the depth camera to the subject locus imaged onto that pixel. In this method, the subject is mapped based on the signal from pixels that image subject loci directly irradiated by the bright features, while omitting or weighting negatively the signal from pixels that image subject loci under the dark features.
