This disclosure describes automatic self-calibration techniques for digital camera devices. In one aspect, a method for performing a calibration procedure in a digital camera device comprises initiating the calibration procedure when a camera sensor of the digital camera device is operating, accumulating data for the calibration procedure, the data comprising one or more averages of correlated color temperature (CCT) associated with information captured by the camera sensor, calculating one or more CCT vectors based on the one or more averages of CCT, and generating gray point correction factors based on the one or more CCT vectors.

In general this disclosure describes techniques for configuring an image sensor of an image capture device based on motion within the scene of interest. In particular, the image capture device analyzes motion between two or more images of the same scene of interest and adjusts the configuration parameters, e. g. , gain and/or exposure time, of the image sensor based on the amount of motion within the scene of interest. For example, the image capture device may configure the image sensor with a large gain and a short exposure time when the scene includes a relatively large amount of motion, thus reducing the blur caused by the large amount of motion. Conversely, the image capture device may configure the image sensor with a small gain and a long exposure time when the scene includes relatively little or no motion, thus reducing the noise caused by large gains.

In a particular embodiment, a method is disclosed that includes determining at least one ambient exposure parameter using an ambient illumination, the at least one ambient exposure parameter including a first sensitivity parameter of an autoexposure controller using the ambient illumination. The method includes determining at least one low-illumination parameter using a first lamp level, the at least one low-illumination parameter including a second sensitivity parameter of the autoexposure controller using the first lamp level, where the autoexposure controller is configured to operate according to at least one high-illumination parameter based on the at least one ambient exposure parameter and the at least one low-illumination parameter. The method further includes performing an image capture operation using a second lamp level that is brighter than the first lamp level, where the at least one high-illumination parameter includes a third sensitivity parameter.

Systems and methods of high dynamic range image combining are disclosed. In a particular embodiment, a device includes a global mapping module configured to generate first globally mapped luminance values within a region of an image, a local mapping module configured to generate second locally mapped luminance values within the region of the image, and a combination module configured to determine luminance values within a corresponding region of an output image using a weighted sum of the first globally mapped luminance values and the second locally mapped luminance values. A weight of the weighted sum is at least partially based on a luminance variation within the region of the image.

A system and method of image capture parameter adjustment using face brightness information is disclosed. In a particular embodiment, a method is disclosed that includes determining a luma value based on a brightness variation within a selected portion of an image, where the selected portion of the image corresponds to at least a portion of a face. The method further includes adjusting an image capture parameter at least partially based on the determined luma value.

Apparatus are provided including an image signal carrier, a luminance information evaluator, and a chrominance information modifier. The image signal carrier is encoded with an image signal including luminance information and chrominance information. The luminance information evaluator evaluates the luminance information in the image signal for a given region within the image to identify when the given region is one of substantially white and substantially dark. The chrominance information modifier is provided to modify the chrominance information corresponding to the given region when the given region is one of substantially white and substantially dark.

Techniques are described for dynamic automatic exposure compensation within image capture devices. The techniques include dynamically adjusting a default target brightness for a scene to compensate an exposure value (EV) selected by an automatic exposure process. A sensor array obtains light information from the scene at a default target brightness and an image capture controller calculates brightness values of a plurality of regions in the scene based on the light information. An automatic exposure compensation module dynamically adjusts the default target brightness based on the brightness values for the plurality of regions in the scene and threshold values set for the sensor array to set an adjusted target brightness. The sensor array may then capture an image frame of the scene using an EV for the adjusted target brightness. The techniques also include building a hysteresis zone to substantially stabilize the adjusted target brightness over a sequence of image scenes.
