IMAGE SIGNAL PROCESSING APPARATUS AND METHOD FOR THE SAME

摘要

The present invention relates to an image processing device and a method thereof. The present invention simultaneously performs both a noise removal process and an interpolation process using four-directional image gradient information defining the difference in color brightness between the adjacent pixels based on the edge direction information calculated in a Bayer image of an image sensor. Therefore, the present invention can improve image qualities and speed.
