Abstract

Systems and methods are disclosed for processing image data to provide adjusted pixel information that achieves smoothed output discontinuities. In one exemplary embodiment, there is provided a method of processing image data including analyzing first display information including pixel data indicative of pixel display on a graphical user interface, detecting one or more ramp steps in the pixel data, and assigning, in association with random number generation and/or threshold setting functionality, a carry possibility for a pixel adjacent the one or more ramp steps. Other exemplary implementations may include generating second display information included adjusted pixel data for pixels adjacent the ramp steps. Consistent with certain implementations, the second display information may include pixel values adjusted according to the carry possibility in one or both of the temporal domain and/or spatial domain.
