Method of controlling the resolution of a hyperspectral image

摘要

Method of controlling the resolution (80) of a hyperspectral image from an image sensor comprising pixels and at least one filter that defines subpixels within each pixel includes defining a window (82) on the image sensor with an array of rows and columns of subpixels; weighting the subpixels (86) within the window based upon one or more predefined parameters of the hyperspectral image to establish a value for a weighted average (88) for the array for the predefined parameters; shifting the window by a predefined number of rows or columns; repeating the weighting and shifting steps for all possible windows (90, 92) on the image sensor; and processing the hyperspectral image based on the weighted averages.
