Method and apparatus for long term image exposure with image stabilization on a mobile device

摘要

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.

1. A method for displaying a live preview image on an electronic device, said method comprising:
computing a history color value and confidence value for each pixel of a sensor of a camera on said electronic device; accessing a new frame of pixels from said camera; and for each pixel in said new frame:
determining if a pixel color is similar to said history color value corresponding to said pixel and if said confidence value corresponding to said pixel is above a predetermined threshold;responsive to a determination that said pixel color is not similar to said history color value and said confidence value is above said predetermined threshold, displaying said history color value on said live preview image when displaying said new frame; andresponsive to a determination that said pixel color is similar to said history color value or said confidence value is below said predetermined threshold, displaying said pixel color on said live preview image when displaying said new frame.
