Abstract
Disclosed is an image processing method based on sensor characteristics. The method includes the following steps: obtaining a constant of a relation 'c≈σ(x)/√{square root over (x)}' between output signals 'x' and the noise standard deviation “σ(x)” of the output signals, in which the output signals are outputted by a sensor based on a sensor gain such as an ISO value of a camera; and calculating an output value of a target pixel according to pixel values within a sampling window, the constant, and a front-end gain such as an auto exposure gain, in which the pixel values include an input value of the target pixel.
