Patent ID: 8265414

Claim:
An image processing device configured to process a moving image shot by a video shooting device in increments of the moving image comprising: a processor; and a correcting means comprising: a low-pass filter property converting means that converts the properties of the low-pass filter into properties according to one or more parameter values detected by a detecting means, and outputs a spatial region signal; a frequency converting means that converts the low-pass filter generated as a spatial region signal into a first signal of a frequency region with the low-pass filter property converting means; a signal generating means configured to generate, based on the first signal, a second signal, the second signal having frequency properties corresponding to the inverse filter in a first frequency band not including a frequency with a gain of zero, and having frequency properties with amplitude thereof below a predetermined value in a second frequency band including a frequency with a gain of zero; a frequency inverse conversion means that converts the second signal into an output filter; and a filtering means that corrects the access element by applying the output filter to the access element, the correcting means correcting at least one access element by changing properties of a low-pass filter indicating an imaging blur according to parameter values describing properties of the imaging blur occurring at a time that the moving image is shot by the video shooting device, generating an inverse filter having properties corresponding to an inverse transfer function of the low-pass filter, and processing the at least one access element by applying the inverse filter to the access element; wherein a frequency property of the low-pass filter contains at least one frequency with a gain of zero, and wherein the inverse filter is not applied when a frequency component of the access element has a gain of zero.
