Abstract: Various examples with respect to method and apparatus for active stereo vision are described. An apparatus may include an electromagnetic (EM) wave emitter, a first sensor and a second sensor. During operation, the EM wave emitter emits EM waves toward a scene, the first sensor captures a first image of the scene in an infrared (IR) spectrum, and the second sensor captures a second image of the scene in a light spectrum. The first image and second image, when processed, may enable active stereo vision.

Abstract: Various schemes pertaining to generating a full-frame color image using a hybrid sensor are described. An apparatus receives sensor data from the hybrid sensor, wherein the sensor data includes partial-frame chromatic data of a plurality of chromatic channels and partial-frame color-insensitive data. The apparatus subsequently generates full-frame color-insensitive data based on the partial-frame color-insensitive data. The apparatus subsequently generates the full-frame color image based on the full-frame color-insensitive data and the partial-frame chromatic data. The apparatus provides benefits of enhancing image quality of the full-frame color image especially under low light conditions.
