Abstract
A method and apparatus for processing an image captured by an image acquisition device having a two-dimensional matrix of non-square pixels with a first aspect ratio. In one aspect of the method, the image is sampled in a color sub-sampled manner such that fewer than three color measurements are known for each pixel location. A processed image is then constructed by processing the fewer than three color measurements known for each pixel to generate one or more interpolated color values at each of the pixel locations. A processed image is then created for rendering on an output device having a square raster with a second aspect ratio which differs from the first aspect ratio. The processed image is processed such that an aspect ratio of the original image captured on the non-square pixels is maintained on the output device.
