Abstract
An image processing method includes inputting input image data captured by an imaging unit, generating an input histogram of the input image data based on the input image data, and correcting the input image data based on noise characteristics data and the input histogram, wherein the noise characteristics data includes data indicating probability of a first characteristic value becoming a second characteristic value due to noise.
Claims13
An image processing apparatus comprising:
- an input unit configured to receive input image data captured by an imaging unit;
- a first generation unit configured to generate an input histogram of the input image data based on the input image data;
- and
- a correction unit configured to change a characteristic value of the input image data to a statistical value of an overlapped region of (a) a distribution of the input histogram and (b) a distribution of noise characteristics data corresponding to the characteristic value.

An image processing apparatus comprising
- an input unit configured to receive input image data captured by an imaging unit;
- a first generation unit configured to generate a distribution derived by dividing numbers of each characteristic value of the input image data by a number of the whole characteristic value of the input image data;
- and
- a correction unit configured to change a characteristic value of the input image data to a statistical value of an overlapped region of (a) a distribution of the input histogram and (b) a distribution of noise characteristics data corresponding to the characteristic value.
