Abstract
A method for performing auto-exposure (AE) control in a depth sensing system includes: performing a rough pattern detection on a first reference frame to obtain a rough pattern detection result regarding a known pattern that is projected by the depth sensing system and calculating a pattern brightness mean; performing a depth decoding process with respect to a second reference frame that is derived based on the pattern brightness mean, thereby to obtain a depth decoding result; performing a mapping process according to the depth decoding result to obtain a mapping result; performing a fine pattern detection on the second reference frame according to the mapping result and the rough pattern detection result to obtain a fine pattern detection result; calculating a frame brightness mean according to the fine pattern detection result; and performing an AE control process over the depth sensing system according to the frame brightness mean.
