Abstract: A device for camera processing is configured to receive a preview image, and determine if the preview image is a high dynamic range (HDR) scene based on brightness values of pixels of the preview image. The device may further determine to use a single frame image capture technique based on a determination that the preview image is not an HDR scene, and determine to use one of a plurality of HDR image capture techniques based on a determination that the preview image is an HDR scene, and further based on motion detected in the preview image. The device may then generate an output image using one or more images captured using the single frame image capture technique or one of the plurality of HDR image capture techniques.

Abstract: A processor generates a depth map from two images, including a high-dynamic range (HDR) image. The processor receives, from a first image sensor, one or more first images, wherein the one or more first images have a first field-of-view (FOV) and a first resolution, and receives, from a second image sensor, one or more second images, wherein the one or more second images have a second FOV and a second resolution. The processor generates a first HDR image from the one or more first images, and performs tone alignment on the one or more second images based on the first HDR image to produce a second HDR image. The processor generates a depth map using the first HDR image and the second HDR image. The processor may use the depth map to apply a bokeh effect to the first HDR image.
