Abstract: Methods, devices, and systems for determining image capture settings based on an audio input are disclosed. In some aspects, a device includes a memory, a camera including a lens and a sensor, and a processor coupled to the camera and the memory. The processor may be configured to receive an audio input, determine contextual information based on the audio input, determine one or more image capture settings based on the contextual information, and output the one or more image capture settings.

Abstract: Methods, systems, and devices for operating a camera-enabled device are described. The camera-enabled device may emit, via a first light emitting source, an infrared light in a physical environment and determine time-of-flight information associated with a target object in the physical environment based on the emitted infrared light. The camera-enabled device may estimate one or more exposure settings based on the time-of-flight information, and emit, via a second light emitting source, a visible light in the physical environment based on the estimated one or more exposure settings. As a result, the camera-enabled device may capture an image of the physical environment based on the emitted visible light and the estimated one or more exposure settings.

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: Aspects of the present disclosure relate to systems and methods for decorrelating one or more saturated regions of an image. In one example, a first phase image and a corresponding second phase image may be obtained. One or more saturated regions of the first phase image and second phase image may be determined. A weight may be applied to each pixel in the one or more saturated regions of the first and second phase images may be weighted to generate a weighted first phase image and a weighted second phase image, and one or more image processing operations may be performed on the weighted first and second phase images.

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: A device may obtain a pixel array representing an image and identify one or more representative metrics for the pixel array. The device may retrieve a first version of a mesh defining a color space, wherein the mesh includes a plurality of vertices and each vertex is associated with a respective set of color balance parameters. The device may identify a point in the color space corresponding to the pixel array based on the one or more representative metrics for the pixel array. The device may receive a tuning input comprising a set of color balance parameters for the point and generate a second version of the mesh by adding the point and the set of color balance parameters to the first version of the mesh. The device may output at least one color-corrected image based at least in part on the second version of the mesh.

Abstract: The disclosure describes flicker detection and correction techniques to improve the quality of captured imagery, such as video or still images. In particular, this disclosure describes flicker correction techniques that compare different image frames to detect flicker. In some embodiments, the comparisons involves summing intensity values associated with rows within the frames and comparing the row sums to generate a difference signal. Detection and correction of flicker may be performed using a first derivative of the difference signal. The first derivative of the difference signal can be used in variety of ways to detect and correct flicker.

Abstract: Apparatus are provided, including an autofocus mechanism. The autofocus mechanism includes an autofocus preliminary operation mechanism and an autofocus continuation mechanism. The autofocus preliminary operation mechanism starts an autofocus of a lens assembly on a given target by causing a focus quality determiner to determine the quality of focus of the lens assembly on the given target while the position of the lens unit is in one focus range and causing an adjustment controller to effect a preliminary adjustment of the lens assembly position within the same one focus range. The autofocus continuation mechanism automatically, upon a lack of successful focus by the autofocus preliminary operation mechanism, continues an autofocus of the lens assembly on the given target by causing the adjustment controller to effect a continued adjustment of the lens assembly position from the one focus range to a different focus range while the focus quality determiner continues to determine the quality of the focus.

Abstract: An imaging system generates a gain for a component of an image format. The gain is at least partially dependent on the brightness of the light source illuminating a scene when an image of the scene was generated. The gain can be used to correct the component of the image format for the color shift in the image caused by the light source. In some instances, the imaging system generates a gain for a plurality of the components of the image format or for all of the components of the image format. The gains can be used to correct the components for the color shift in the image caused by the light source.
