ABSTRACT:
High frequency components are efficiently extracted from blurred images, and blur correction is efficiently performed. A blur analyzing means judges whether an image is a blurred image. If the image is judged to be a blurred image, blur data Q, which includes a blur width, is generated and transmitted to a blur correcting means. The blur correcting means extracts high frequency components from the image if the blur width is less than a predetermined threshold value, and performs blur correction by adding the high frequency components to the image. Meanwhile, if the blur width is greater than or equal to the threshold value, a reducing means reduces the size of the image to obtain a reduced image. Then, the blur correcting means extracts high frequency components from the reduced image, and performs blur correction by emphasizing and adding the extracted high frequency components to the reduced image.
