Abstract:
1. An image processing apparatus comprising: an image correction processing unit configured to correct an input image so as to generate a corrected image; and a super-resolution processing unit configured to receive the corrected image generated by the image correction processing unit and increase a resolution of the corrected image through super-resolution processing so as to generate a high-resolution image; wherein the image correction processing unit performs at least one of a time-direction noise removal process, a space-direction noise removal process, a compression noise removal process, and an aperture control correction process; and wherein the super-resolution processing unit generates the high-resolution image corresponding to the input image on the basis of a low-resolution image (LR image) received from the image correction processing unit and a high-resolution image (SR image) pregenerated for the previous frame, and wherein the super-resolution processing unit includes a high-resolution difference image generating unit, a time-direction noise removal unit, a first addition processing unit, and a second addition processing unit, and wherein the high resolution difference image generating unit motion compensates the high-resolution image (SR image) on the basis of a motion vector computed using the high-resolution image (SR image) and the low-resolution image (LR image), generates a difference image between the motion-compensated high-resolution image (SR image) and the low-resolution image (LR image), and generates a high-resolution difference image by performing upsampling and inverse motion compensation on the difference image, the time-direction noise removal unit performs removal of noise in the time direction from a low-frequency component-removed image of the high-resolution difference image, the first addition processing unit adds an image processed by the time-direction noise removal unit to a low-frequency component image of the high-resolution difference image, and the second addition processing unit adds an output of the first addition processing unit to the high-resolution image (SR image) so as to generate the high-resolution image corresponding to the received low-resolution image (LR image).
