Abstract: A device for image capture comprises a memory and one or more processors coupled to the memory and configured to: receive, during a preview mode or a recording, a first image, generate a first saliency map indicative of relative saliency of different regions within the first image, wherein the relative saliency of the different regions is indicative of a likelihood of attracting viewer gaze, generate one or more additional images based on manipulating pixels in the first image, generate one or more additional saliency maps indicative of relative saliency of different regions within the one or more additional images, and determine, during the preview mode or the recording, a camera setting based on the first saliency map and the one or more additional saliency maps.

Abstract: Methods, systems, and devices for image processing are described. Devices with one or more sensors (e.g., devices with multiple cameras, such as a dual camera device) may perform flash metering techniques, using an auxiliary camera, during a flash duration used for main camera image capture. For example, a dual camera device may control camera flash parameters (e.g., flash duration, flash power), via auxiliary camera flash metering, during main camera image capture (e.g., during main camera exposure for image capture operations). A main camera may begin exposure and a flash may be initiated. During the flash, an auxiliary camera may be configured to perform flash metering operations (e.g., via images captured by the auxiliary camera). Based on flash metering information from the auxiliary camera, the dual camera device may configure or adjust camera settings (e.g., exposure settings, flash duration, flash end time, flash power) during main camera exposure and image capture.

Abstract: Methods, systems, and devices for adjusting exposure at a camera of a device are described. The described techniques relate to improved methods, systems, devices, or apparatuses that support faster automatic exposure control (AEC). Generally, the described AEC techniques provide for alignment of exposure setting adjustments (e.g., exposure time adjustments, gain adjustments, etc.) with 2-frame gain adjustment delays. For example, gain adjustment calculations based on image sensor measurements associated with a current frame (e.g., frame N) may take into consideration exposure time adjustment calculations from the previous frame (e.g., frame N−1), such that AEC algorithms may use exposure time adjustment calculations from the previous frame (e.g., frame N−1) and gain adjustment calculations from the current frame (e.g., frame N) to adjust exposure settings with a 2-frame delay (e.g., such that updated exposure settings may take effect on frame N+2).

Abstract: Apparatus and methods employing a PDAF optical system are disclosed herein. An example apparatus includes an image sensor comprising a plurality of pixels. The plurality of pixels include a set of pixels configurable to be imaging pixels or focus pixels. The image sensor is configured to generate image data of a scene based on received light at the plurality of pixels. The example apparatus also includes a processor coupled to the image sensor. The processor may be configured to receive first image data of a first frame of the scene, determine at least one region of interest or region of non-interest of the first frame, select, based on the determined at least one region of interest or region of non-interest, a subset of the set of pixels to be focus pixels, and cause the selected subset of the set of pixels to operate as focus pixels.
