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: In one implementation, an electronic visual-rendering device includes an eye-tracking sensor and at least a first component. The eye-tracking sensor is configured to detect an eye-close event and, in response, output an eye-close-event message. The first component is configured to operate in at least a normal-power mode and a first low-power mode. The first components is configured to transition from operating in the normal-power mode to operating in the first low-power mode in response to the eye-tracking sensor's output of the eye-close-event message.

Abstract: Methods, systems, and devices for dual phase detection auto focus (PDAF) power optimization are described. A camera device may capture a frame including a pixel array representing a scene. In some examples, each pixel of the pixel array may be a phase detection (PD) pixel having one or more values, or one or more PD pixels positioned randomly across the pixel array. The camera device may identify a configuration of the pixel array, and determine a condition of the pixel array relative to the configuration. The configuration may be a binning configuration or a frame pattern configuration, and the condition may include an illumination condition related to the pixel array representing the scene. The camera device may determine and apply a reconfiguration to at least a portion of the pixel array based on the condition of the pixel array, and determine a lens position of the camera device therewith.

Abstract: Methods, systems, and devices are described for processing Visual Light Communication (VLC) signals with a reduced number of pixels while maintaining a substantially complete field of view. One method may include receiving one or more VLC signals at an array of pixels and sampling their intensity. The sampling may comprise additively combining analog signals obtained from two or more pixels having like color to generate a plurality of combined VLC signal samples. The VLC signals may be decoded based on a plurality of the combined VLC signal samples.

Abstract: Methods and devices for camera initialization are disclosed. In some aspects, a device includes a first camera to capture one or more first image frames, a second camera to capture one or more second image frames, and a camera controller coupled to the first camera and the second camera. The camera controller is configured to initialize the first camera, to cause the second camera to capture one or more second image frames while initializing the first camera, to determine an initial capture setting for the first camera based on the one or more second image frames captured by the second camera, and to complete initialization of the first camera using the initial capture setting.
