Abstract: Systems, methods, and non-transitory media are provided for automatic exposure control. An example method can include receiving pixel values captured by a photosensor pixel array (PPA) of an image sensor, wherein one or more pixel values from the pixel values correspond to one or more sensitivity-biased photosensor (SBP) pixels in the PPA and one or more saturated pixel values from the pixel values correspond to one or more other photosensor pixels in the PPA; determining, based on the one or more pixel values, an actual pixel value for the one or more pixel values and/or the one or more saturated pixel values; determining an adjustment factor for at least one of the pixel values based on the actual pixel value and a target exposure value; and based on the adjustment factor, correcting an exposure setting associated with the image sensor and/or at least one of the pixel values.

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.

Abstract: In some aspects, a device may receive, from a pixel array of a camera, a first image. The device may configure, based at least in part on the first image, a setting of a filter. The filter may be included within a filter array that is arranged within the camera in association with the pixel array. The device may cause the pixel array to capture a second image. Numerous other aspects are described.
