Abstract
A method and an electronic device for reducing digital image noises are described. The method includes the steps of sequentially selecting a pixel from a digital image, and setting the pixel as a target pixel; defining a first area, and setting at least two of the rest pixels surrounding the target pixel in the first area as adjacent pixels; setting a first weighted area; setting a second weighted area corresponding to the first weighted area; computing a weight of the adjacent pixel located at a center position of the second weighted area by using a piecewise linear curve according to a similarity value of the first weighted area and the second weighted area; computing a weighted average of all the adjacent pixels and the target pixel, to determine a new value of the target pixel; and performing the above steps repeatedly, till all the pixels are processed.
