Method of reducing noise in images |
摘要 |
An image noise reducing method that can properly reduce CCD noise which emerges in an image imported from a digital camera is provided. The method includes applying a first filtering step to luminance component image data of the image with each pixel of the luminance component image data being designated as a target pixel, thereby creating luminance component image data with its entirety smoothened, and applying a second filtering step to color-difference component image data of the image with each pixel of the color-difference component image data being designated as a target pixel, thereby creating color-difference component image data with its entirety smoothened |
