PROBLEM TO BE SOLVED: To remove noise further effectively.SOLUTION: There is provided an image processing device including a color space conversion unit that converts a first color space expressing an input image into a second color space, a frequency conversion unit that converts an input image expressed in the second color space into a frequency component, a CSF setting unit that sets a CSF (Contrast Sensitivity Function) corresponding to the second color space, and a level control unit that controls a level of the frequency component of the input image for each band according to the CSF. This technique can be applied to an image processing device that performs noise reduction processing on images. |
