Abstract
A method for displaying a live preview image on a mobile device is disclosed. The method includes computing a history color value and confidence value for each pixel of a sensor of a camera. Further, it includes obtaining a new frame of pixels from the camera. Subsequently, for each pixel in the new frame, the method includes: (a) determining if a pixel color is similar to a corresponding history color value and if a confidence corresponding to a pixel is above a predetermined threshold; (b) if the pixel color is not similar to the history color value and the confidence is above the predetermined threshold, displaying the history color value on the preview when displaying the new frame; and (c) if the pixel color is similar to the history color value or the confidence is below the threshold, displaying the pixel color on the preview instead.
