摘要： A method and apparatus for determining an auto white balance (AWB) gain based on determined depth information. The method may include receiving an image captured by an image sensor, determining depth information associated with the captured image, assigning weights to a plurality of illuminants based on the determined depth information, determining an auto white balance gain based on the assigned weights and statistics of the captured image, and applying the auto white balance gain to the captured image.

摘要： An apparatus includes an initializer configured to adjust one or more settings of a camera prior to initialization of the camera. The one or more settings are adjusted based on an indication of motion detected using at least one measurement performed by a sensor device. The apparatus further includes a processing device configured to execute a camera application to initialize the camera after adjustment of the one or more settings.

摘要： Certain aspects relate to systems and techniques for color temperature analysis and matching. For example, three or more camera flash LEDs of different output colors can be used to match any of a range of ambient color temperatures in a non-linear space on the black body curve. The scene color temperature can be analyzed in a preliminary image by determining actual sensor R/G and B/G ratios, enabling more accurate matching of foreground flash lighting to background lighting by the reference illuminant for subsequent white balance processing. The current provided to, and therefore brightness emitted from, each LED can be individually controlled based on the determined sensor response to provide a dynamic and adaptive mix of the output colors of the LEDs.

摘要： An image capture device that includes an adjustment circuit configured to monitor image parameters, generate updated image settings for the image capture device in response to the monitored image parameters, and transmit the updated image settings to one or more processors. The updated image settings configure the one or more processors to determine whether to transition the image capture device from a dynamic scene mode to a static scene mode based on a first image parameter included in the monitored image parameters, wherein the first image parameter is different from a second image parameter used to determine to transition the image capture device from the static scene mode to the dynamic scene mode, and to suspend generation of all or less than all of the updated image settings in response to determining to transition the image capture device from the dynamic scene mode to the static scene mode.

摘要： Aspects of the present disclosure relate to systems and methods for calibrating a flash for image capture. An example method may include receiving, from a camera, a first image of a scene captured with a first flash light source emitting light with a first color temperature and with a second flash light source emitting light with a second color temperature different from the first color temperature. The first flash light source and the second flash light source may be derived based on a first flash calibration setting of a number of stored flash calibration settings. The example method may also include determining a difference between a desired color characteristic for the first flash calibration setting and a color characteristic of the first image. The example method may further include adjusting the first flash calibration setting based on the determined difference.

摘要： This application relates to capturing an image of a target object using information from a time-of-flight sensor. In one aspect, a method may include a time-of-flight (TOF) system configured to emit light and sense a reflection of the emitted light and may determine a return energy based on the reflection of the emitted light. The method may measure a time between when the light is emitted and when the reflection is sensed and may determine a distance between the target object and the TOF system based on that time. The method may also identify a reflectance of the target object based on the return energy and may determine an exposure level based on a distance between the target object and a reflectance of the target object.
