Abstract
A method for determining a value for an unknown picture element (pixel) T based on neighboring pixel values of a checkerboard decimated color plane. Immediate and extended neighborhood pixel values are selected. In one configuration, immediate neighborhood pixel values are averaged. In another configuration, all neighborhood pixels are averaged. A binary pattern is determined by comparing the average with each immediate and extended neighborhood pixel values. The binary pattern is reduced to identify a set of coefficients for the binary pattern. A summed cross-product is computed for the set of coefficients and each pixel value of the immediate and extended neighborhoods. In one configuration, coefficients are stored in look up tables, where different tables correspond to different input image types. In another configuration, multiple lookup tables are stored within input images, allowing different image reconstruction options based on the embedded tables. In a further configuration, an image capturing device analyzes the image being captured, and embeds a lookup table within the image corresponding to the image type for the image, e.g., fast action shot, low-lighting, portrait, etc.
