| 发明名称 | Image processing method | ||
| 摘要 | An image processing method is provided and includes the following steps. A source image arranged in a Bayer pattern is captured. A first-order image process is performed on the source image to produce a first image in YCbCr format. A second-order image process is performed on the source image to produce a second image in YCbCr format. Then, a noise-reducing process is performed on the first image in YCbCr format to produce a noise-reduced image. A blending operation is performed on luminance image of the noise-reduced image and luminance image of the second image in YCbCr format, and thereafter a chrominance image is combined with the blended image to produce a processed image. A noise reducing degree of the noise-reduced image is higher than that of the second image in YCbCr format. | ||

| 主权项 | 1. An image processing method, comprising: receiving a source image; performing a first-order image process on the source image to produce a first image in YCbCr format; performing a second-order image process on the source image to produce a second image in YCbCr format; performing a noise-reducing process on the first image in YCbCr format to produce a noise-reduced image; and performing a blending operation on a luminance image of the noise-reduced image and a luminance image of the second image in YCbCr format and combining with a chrominance image of the second image in YCbCr format to produce a processed image, wherein a noise reducing degree of the noise-reduced image is higher than a noise reducing degree of the second image in YCbCr format. | ||
