An example method to control a light source in structured light imaging associated with a target includes obtaining two-dimensional image information and depth information of an image including the target and a scene, associating the depth information with pixels of the image, selecting a first set of pixels of the pixels based on a first set of the depth information and a second set of pixels of the pixels based on a second set of the depth information, calculating a first average pixel luminance (APL) of the first set of pixels and a total APL of the first and the second sets of pixels, obtaining a weighted APL based on the first APL and the total APL and controlling the light source based on the weighted APL.

Method and apparatus to control light source in structured light imaging

An example method to render an image includes obtaining two-dimensional image information of the image including a target and a scene and depth information associated with a first set of pixels and a second set of pixels of the image. The first set of pixels correspond to the target and the second set of pixels correspond to the scene. In response to depth information associated with a pixel of the image being in the predetermined range, the example method includes associating a first depth index with the pixel. Otherwise, the example method associates a second depth index with the pixel. The example method further includes calculating a weighted average picture level of the image based on grayscale values of pixels of the image, the first depth index and/or the second depth index and rendering the image based on the weighted average picture level.
