Abstract
A method for camera focus adjustment includes, at a computing system, receiving a depth image of a surrounding environment captured by a depth camera of the computing system. The depth image includes a plurality of depth pixels each encoding depth values corresponding to distances between the depth camera and objects in the surrounding environment. One or more depth pixels of the plurality of depth pixels are identified as a region of interest (ROI). Based on the depth values of the one or more depth pixels, a focus of an environmental imaging camera of the computing system is adjusted.
Claims20
A method for camera focus adjustment, the method comprising:
- at a computing system, receiving a depth image of a surrounding environment captured by a depth camera of the computing system, the depth image including a plurality of depth pixels, and the plurality of depth pixels each encoding depth values corresponding to distances between the depth camera and objects in the surrounding environment;
- identifying one or more depth pixels of the plurality of depth pixels as a region-of-interest (ROI);
- and
- adjusting a focus of an environmental imaging camera of the computing system based at least in part on the depth values of the one or more depth pixels.
A head-mounted display device (HMD), comprising:
- an environmental imaging camera;
- a depth camera;
- a logic subsystem;
- and
- a storage subsystem holding instructions executable by the logic subsystem to:
- receive a depth image of a surrounding environment captured by the depth camera, the depth image including a plurality of depth pixels, and the plurality of depth pixels each encoding depth values corresponding to distances between the depth camera and objects in the surrounding environment;
- identify one or more depth pixels of the plurality of depth pixels as a region-of-interest (ROI);
- and
- adjust a focus of the environmental imaging camera based at least in part on the depth values of the one or more depth pixels.
A method for camera focus adjustment, the method comprising:
- at a head-mounted display device (HMD), receiving an environmental image of a surrounding environment captured by an environmental imaging camera of the HMD;
- detecting an object of interest at a pixel-space position in the environmental image;
- receiving a depth image of the surrounding environment captured by a depth camera of the HMD, the depth image including a plurality of depth pixels, and the plurality of depth pixels each encoding depth values corresponding to distances between the depth camera and objects in the surrounding environment;
- identifying one or more depth pixels of the plurality of depth pixels as a region-of-interest based at least in part on determining that the pixel-space position of the object of interest in the environmental image corresponds to the one or more depth pixels in the depth image;
- and
- adjusting a focus of the environmental imaging camera based at least in part on the depth values of the one or more depth pixels.
