Abstract

A non-transitory computer-readable medium encoded with a computer-readable program, which when executed by a processor, will cause the processor to execute an image processing method, the image processing method including establishing a zero crossing region from a target image onto a screen, wherein the zero crossing region comprises a corresponding value. The method further includes receiving a variable input and an integration time input, wherein the variable input comprises a frequency number for an image accumulation procedure, and wherein the integration time comprises a time period for which an aperture for a sensor receives incoming signals. Additionally, the method includes performing the image accumulation procedure. Moreover, the method includes producing a final greyscale image by adding a plurality of sets of vertically shifted pixel values, wherein the frequency number for the image accumulation procedure ranges from 3 to 20.
