Digital picture noise reduction by combining high-noise and low-noise processed pictures

摘要

A method for processing a digital picture is disclosed. The method may include steps (A) to (C). Step (A) may generate a first picture by processing the digital picture using a first noise reduction technique in a circuit. Step (B) may generate a second picture by processing the digital picture using a second noise reduction technique. The first noise reduction technique may achieve a higher noise reduction than the second noise reduction technique. Step (C) may generate an output picture by combining the first picture and the second picture.

1. A method for processing a digital picture, comprising the steps of:
(A) generating a first picture by processing said digital picture using a first noise reduction technique and a first color processing technique in a circuit; (B) generating a second picture by processing said digital picture using a second color processing technique that is different than said first color processing technique; (C) converting both said first picture and said second picture from a particular color space to a different color space prior to being combined and after both said first color processing technique and said second color processing technique; and (D) generating an output picture by combining said first picture and said second picture.
