A method, non-transitory computer readable medium, and apparatus for enhancing an edge of a non-saturated object are disclosed. For example, the method detects a plurality of transition pixels, determines a gray value for one or more of the plurality of transition pixels is greater than a threshold value, identifies one or more edge pixels from the one or more of the plurality of transition pixels that has the gray value greater than the threshold value when the one or more of the plurality of transition pixels is not within an input block of pixels having all of the pixels in the input block with a respective gray value greater than the threshold and applies an edge enhancement to each one of a plurality of input blocks containing the one or more edge pixels.
