Patent ID: 7792380

Claim:
An image processing device, comprising: parameter acquiring means for acquiring a parameter corresponding to a deblurring amount of an image to be deblurred, wherein the parameter acquiring means includes a user interface unit configured to acquire the parameter from user input to the user interface unit; feature quantity detecting means for detecting a feature quantity of said image to be deblurred; parameter correcting means for correcting the parameter acquired by the user interface unit based on both (1) a value of the detected feature quantity, and (2) a value of the parameter acquired by the user interface unit, wherein, when a first feature quantity as a maximal value of said feature quantity of said image to be deblurred is smaller than a second feature quantity as said maximal feature quantity that corresponds to said acquired parameter, said parameter correcting means does not change said acquired parameter, and when the first feature quantity is larger, the acquired parameter is set to said parameter that corresponds as the maximal feature quantity of a third feature quantity as a feature quantity greater than said first feature quantity; and deblurring means for correcting the blurring of said image to be deblurred based on the parameter corrected by the parameter correcting means.
