Patent ID: 8345163

Claim:
An image processing device comprising: a motion vector detection section for receiving a first video signal and a second video signal, the second video signal being equivalent to the first video signal with an advance or delay of at least one frame, and detecting therefrom a motion vector pertaining to a pixel of interest in the first video signal; and an image correction section for using the motion vector detected by the motion vector detection section to reduce motion blur in the first video signal; the image correction section including a motion blur estimator for estimating, from the motion vector, a direction and a magnitude of the motion blur, a filtering unit for filtering the first video signal, using filter coefficients corresponding to the estimated direction and magnitude, and a correction strength adjuster for adjusting a strength of a correction applied to a pixel value of the pixel of interest, responsive to a degree of variation of pixel values in a vicinity of the pixel of interest, the degree of variation being expressed as a difference between the pixel value of the pixel of interest and a mean value of the pixel values in the vicinity; wherein the filtering unit performs a low-pass filtering operation, using clipped pixel values obtained by clipping pixel values of pixels in a neighborhood of the pixel of interest so that an absolute value of a difference between the pixel value of the pixel of interest and the pixel values of the pixels in the neighborhood does not exceed a predetermined threshold.
