IMAGE NOISE REDUCTION APPARATUS AND METHOD |
摘要 |
Provided is an image noise reduction method and apparatus in consideration of brightness of an image in a camera using an image pickup device such as a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS). The method includes: detecting a degree of image motion by using data from a plurality of frames which are picked up; detecting brightness of an image which is picked up; determining a ratio between current frame data and previous frame data according to the image motion degree and the brightness of the image; and combining the current frame data with the previous frame data according to the determined frame data ratio. |
