Abstract: Dynamic white point management techniques include determining a white point of ambient light proximate to a display. A color profile adjustment is determined based upon the determined white point and intensity of the ambient light. The image color space is transformed to a display color space for rendering on the display based on the determined adjusted to the color profile.

Abstract: An image is remotely processed over a network. An electronic device is characterized based on a unique identifier associated therewith and properties data, which relate to display related properties of the device. Local data is collected from the device in relation to real-time conditions and control data and, which correspond to the device in relation to the characterizing. The image is remotely generated for download to the device and includes processing data. The processing data are based on the properties data and the local data.

Abstract: Embodiments of the present invention are directed to methods and systems for performing automatic lens shading correction using module-specific calibrations. According to one aspect of the invention, a method is provided that is performed over three main stages. During a first stage, radial symmetric component data is determined that is common to camera modules of the type to be calibrated. During the second stage, the actual measurement of the shading profile of one or more specific camera modules is performed. In the third and final stage is the extrapolation stage, the base measurement surfaces of a camera module type determined in the first stage are extrapolated and modified with the module-specific Bezier correction surface and calibration data of the second stage. The output surfaces of this third and final stage are used to correct for the shading profile in the camera module, depending on the light-source estimation.
