A method of forming an output image based on first and second input images includes the steps of: (a) selecting a desired mix-ratio between the first and second input images; (b) determining an angle phi based on the selected mix-ratio; and (c) extending a diagonal line, at the angle of phi between a vertical axis and a horizontal axis, in which the vertical axis includes a first set of gray levels from the first input image and the horizontal axis includes a second set of gray levels from the second input image. The method further includes the steps of: (d) computing an area A included within the horizontal and vertical axes and the diagonal line, in order to determine a gray level value of a pixel of the output image based on a probability value of k=A/n2, where, n is a maximum gray level value of each of the input images, and k varies from 0 to 1. In one embodiment, the fixed probability distribution is uniform, and the input and output image bit depths are equal to each other. Then the gray level value of z of the output image becomes A/n. |
