Colorizing a black-and-white image to facilitate the identification of a pattern in the image

摘要

The invention facilitates the identification of a pattern in an image by displaying a multiplicity of versions of the image in sequence at a specified rate. The display of each version of the image includes only pixels having a specified grayscale value or a grayscale value in a specified range of grayscale values that is smaller than the range of grayscale values for all pixels of the image. Each pixel displayed in a version of the image is displayed in the color corresponding to the grayscale value of that pixel. The specified grayscale value or range of grayscale values for which pixels are displayed in each successive displayed version of the image is incremented or decremented from the specified grayscale value or range of grayscale values for which pixels are displayed in the immediately previous displayed version of the image by a specified grayscale value increment or decrement.
