Abstract
A method and device for improving the accuracy of depth information derived from a structured-light image for a regular image are disclosed. In one example, an additional structured-light image is captured before a first structured-light image or after a regular image. The depth information for the regular image can be derived from the first structured-light image and corrected by incorporating depth information from the additional structured-light image. A model for depth information can be used to predict or interpolate depth information for the regular image. In another example, two regular sub-images may be captured with a structured-light image in between. If substantial frame differences or substantial global motion vector/block motion vectors are detected, the two regular sub-images will not be combined in order to avoid possible motion smear. Instead, one of the two sub-images will be selected and scaled as the output regular image.
