IMAGE PROCESSING DEVICE, IMAGE SENSING APPARATUS, AND IMAGE PROCESSING METHOD |
摘要 |
An image processing device is comprised of: a frequency component resolution section (110) for resolving an image obtained from an image sensor having a light-shielded pixel area and a non-light-shielded pixel area into two or more frequency components; a noise amount calculation section (1231a, 1232a) for calculating a noise amount for the frequency component based on the frequency component in the light-shielded pixel area; a noise suppression section (1233, 1234) for suppressing the noise component for the frequency component in the non-light-shielded pixel area according to the noise amount that has been calculated by the noise amount calculation section; and a frequency component synthesis section (120) for synthesizing the frequency component that has been resolved by the frequency component resolution section to thereby form an image. |
