摘要： Methods, apparatuses and systems for storing approximations of multiple spatial pixel value adjustment surfaces for use in pixel value correction. The adjustment surfaces may be used for positional gain adjustment. A representation of the multiple adjustment surfaces is stored as coefficients representing a multi-dimensional solid of two-dimensional adjustment surfaces. The stored coefficients are used to determine a plurality of additional sets of coefficients which sets are then in turn used to determine pixel correction values of adjustment surfaces.

摘要： Methods, systems and apparatuses are disclosed for approximating vertical and horizontal correction values in a pixel value correction calculation. Multiple vertical and/or horizontal correction curves are used and may be employed for one or more color channels of the imager. The use of multiple correction curves allows for a more accurate approximation of the correction curves for image pixels.

摘要： Methods, apparatuses and systems are disclosed for providing pixel value corrections in accordance with the focal length of a variable focal length lens used to capture an image. Two or more adjustment surfaces, each corresponding to a focal length of said lens, are stored. If an image is captured using a focal length of the lens which does not correspond to a stored adjustment surface, an interpolated or extrapolated adjustment surface is determined and applied to a captured image.

摘要： Surface generation and positional gain adjustment techniques for an imager are described. Embodiments of the techniques use zones having flexible boundaries which can be reconfigured depending upon the type of lens being used in a given application. Each pixel within each zone is multiplied by a correction factor dependent upon the particular zone while the pixel is being read out from the array. The correction factors comprise coefficients that are different for each color channel and in some instances different for each corner of each color channel.
