Abstract:
1. An imaging system comprising: an edge-aware interpolator to perform an edge-aware demosaicing process on image sensor data to generate pixel-edge data; a difference data generator to generate difference data representing a difference between pixel-averaged data and the pixel-edge data; and a video data generator to generate video output data by adding the pixel-averaged data to the difference data weighted by a correction factor, wherein the correction factor is proportional to an amount of edge content in the image sensor data, wherein the image sensor data comprises Bayer data, wherein the video output data comprises red-green-blue intensity data, and wherein the difference data generator is configured to generate separate difference data comprising red difference data, green difference data, and blue difference data, wherein the video data generator is configured to use the separate difference data to generate the video output data when the correction factor is greater than a low threshold value and less than or equal to a high threshold value and wherein the video data generator is configured to use single-value difference data to generate the video output data when the correction factor is greater than the high threshold value.
