摘要： According to one embodiment, a video signal interpolation device includes a motion vector detector, an interpolation frame generator, an analyzer, and an enhancer. The motion vector detector detects a motion vector from two consecutive image frames. The interpolation frame generator generates an interpolation frame from the image frames based on the motion vector detected by the motion vector detector. The analyzer detects uniform motion in a predetermined direction from the motion vector detected by the motion vector detector. The enhancer performs an enhancement process on the interpolation frame from the same direction as the direction of the uniform motion detected by the analyzer.

摘要： PROBLEM TO BE SOLVED: To suppress deterioration of image quality that can occur when performing frame interpolation.SOLUTION: A frame interpolation apparatus 100 is supplied with a dynamic image from an image generating apparatus 300 that adds n (n is a natural number) copy frames subsequent to each frame of the dynamic image and has the number of frames increased to output them. A frame acquisition unit 20 of the frame interpolation apparatus 100 samples one frame at the period of every (n+1) frame from the dynamic image. An interpolation frame generation part 30 generates interpolation frames among frames sampled by the frame acquisition unit 20. An identity judgment part judges identity of continuous frames of the dynamic image. A sampling point change part moves a sampling point while the period remains fixed when the frames judged to be identical by the identity judgment part continues for smaller or larger than (n+1) frames and meet a certain condition.

摘要： An improved motion compensated interpolation of images in video sequences, in particular, for use in up-conversion processing. In order to achieve a smooth object motion in the interpolated image sequence, separate image areas are processed differently if an image change occurs in the video sequence. While for one image area motion compensation is suspended, the other image area is subjected to motion compensated interpolation.

摘要： PROBLEM TO BE SOLVED: To provide an interpolation frame generating method for properly interpolating a pixel in an occlusion region of an interpolation frame.
SOLUTION: In an interpolation frame generating method, a first motion vector from a first reference frame to a second reference frame is estimated by a motion estimation unit 101. An interpolation frame generating unit 102 assigns a pixel value and a second motion vector based on the first motion vector to generate an interpolation frame. An occlusion region generated in the interpolation frame is detected by an occlusion detection unit 103. An occlusion filtering unit 104 determines continuity of the occlusion region and a non-occlusion region, and assigns any one of the first and second reference frames to the occlusion region based on the second motion vector assigned to the non-occlusion region having continuity.

摘要： In an image display device having a frame rate converting (FRC) portion, it is possible to prevent image degradation of a combined image display portion such as an OSD and PinP attributed to the FRC process. The image display device includes: an FRC portion 10 for converting the number of frames of an input image signal by interpolating an image signal subjected to a motion compensation process between the frames of the input image signal; an OSD processing portion 14 for superposing an OSD signal on the input image signal, and a controlling portion 15. The FRC portion 10 has a motion vector detecting portion 11e for detecting a motion vector between the frames of the input image signal, an interpolation vector evaluating portion 11f for allocating interpolation vector between frames based on the motion vector information, and an interpolation frame generating portion 12d for generating an interpolation frame from the interpolation vector. When the OSD signal is superposed on the input image signal, the controlling portion 15 disables the motion compensation process of the FRC portion 10 by making the motion vector detected by the motion vector detecting portion 11e 0 vector.
