Abstract
A plurality of depth planes corresponding to a scene within a field of view of a camera of a computing device can be computed based on stereographic techniques, infrared transceivers, ultrasonic transceivers, among other approaches. The depth planes can be utilized to independently meter subject matter of interest (e.g., person, object, region, etc.) corresponding to each depth plane to obtain image statistics for each depth plane. The image statistics can be analyzed to determine optimal settings (e.g., focus, exposure, white balance, etc.) for each depth plane, and a camera can be configured to acquire image data according to the optimal settings for one or more of the depth planes. Further, the image statistics can be leveraged for processing portions of the image data that are not optimized during capture. Thus, a final image can reflect optimizations for multiple subject matter of interest located at various distances from a computing device.
