摘要： To interpolate a frame between the current frame and a first delayed frame preceding the current frame, an image processing device generates test interpolation data for the first delayed frame from data in point-symmetric positions in the current frame and in a second delayed frame preceding the first delayed frame. Motion vectors pointing from the first delayed frame to the current frame are found by evaluating different test interpolation data against the actual data of the first delayed frame. These motion vectors are converted to pairs of motion vectors pointing from the first delayed frame and the current frame to the interpolated frame, and these pairs of motion vectors are used to detect occlusion and generate accurate data for the interpolated frame from the data of the first delayed frame and the current frame, excluding occluded data.

摘要： Motion blur at a pixel of interest in a video signal is corrected adaptively by detecting a motion vector of the pixel of interest, estimating the direction and magnitude of the motion blur from the motion vector, and filtering the video signal at the pixel of interest. The filtering process uses the pixel values of the pixels in a neighborhood of the pixel of interest, clipped so that they do not differ too greatly from the pixel value of the pixel of interest, and low-pass filtering coefficients selected according to the estimated direction and magnitude. The filtered value is used to calculate a gain factor for correcting the pixel value of the pixel of interest. The strength of the correction is adjusted according to the difference between the pixel value of the pixel of interest and the mean pixel value in its vicinity. The adjustment and clipping prevent overcorrection.

摘要： Provision is made for obtaining a high-quality image with noise, such as ringing, reduced. An image processing device includes an image correction means for applying image-shake correction processing to an input image; a correction-image characteristic detection means for detecting a characteristic of a correction image obtained through the image-shake correction processing; a first characteristic-determination means for outputting selection information, based on a characteristic-detected correction image obtained through detection of the characteristic of the correction image; and an image outputting means for outputting the input image or the correction image, based on the selection information. As a result, it is made possible to obtain a high-quality image with noise reduced.
