摘要： PROBLEM TO BE SOLVED: To provide a technique that expresses motion of a telop smoothly with a simple configuration. SOLUTION: An image processing apparatus includes a motion vector detection means, a telop detection means, a first correction means, a second correction means, a control means, and a generation means. The motion vector detection means divides input video into a plurality of blocks, and detects a motion vector for every block. The telop detection means detects a horizontal telop and a vertical telop from the input video. The first correction means rectifies the motion vector of a block which contains the horizontal telop among the plurality of blocks. The second correction means rectifies the motion vector of a block which contains the vertical telop among the plurality of blocks. When both of the horizontal telop and the vertical telop are detected by the telop detection means, the control means controls the first correction means and the second correction means so as to perform correction by one correction means and omit correction by another correction means between the first correction means and the second correction means. The generation means generates an interpolation frame using the motion vector for every block. COPYRIGHT: (C)2011,JPO&INPIT

摘要： According to one embodiment, to detect a still subtitle part included as a part of an image in a video signal, the still subtitle detection apparatus detects in pixel units a subtitle part from a video frame formed of pixels. The apparatus includes a subtitle part determination module and a still subtitle detection module. The subtitle part determination module determines, as the subtitle part, a pixel or pixel group on the high-luminance region side (white peak) that neighbors the detection position of an image edge where a luminance level changes or on the low-luminance region side (black bottom) that neighbors the detection position of the image edge where the luminance level changes. When it is detected that the subtitle part remains unchanged by comparing two continuous video frames along the time axis, the still subtitle detection module detects the subtitle part as a still subtitle.

摘要： PROBLEM TO BE SOLVED: To provide a video signal processor capable of appropriately improving image quality degradation caused by imaging blurring. SOLUTION: In an imaging blurring suppression processing part 2, respective pixel values are successively corrected in each frame period, and correction processing is executed utilizing a correction result in an already corrected pixel within the input video image of the present frame period when performing correction in a pixel n of interest. Thus, such correction processing can be made to function as IIR filter processing in a spatial direction. Thus, imaging blurring is suppressed even in input video signals including a spatial frequency component higher than before, and the image quality degradation caused by the imaging blurring is appropriately improved (clear images are obtained).

摘要： This invention enables reduction of moving blurring in a hold-type display device and reduce flicker in an impulse-type display device, and also enables to suppress distortion such as ghost or tail-blurring in pursuit. A LPF generates low-frequency image data from input frame. High-frequency emphasized image data is also generated using a subtractor and an adder. A SizeDown unit reduces the low-frequency image data to decrease the number of pixels. A motion detection/motion application unit performs motion detection and motion application from the reduced image data of the frame of interest and that of the next frame to generate reduced image data located at the intermediate position between them. A SizeUp unit enlarges the generated reduced image data. Another LPF filters the enlarged image data and outputs the result as low-frequency image data. A switch alternately outputs the high-frequency emphasized and the low-frequency images at a speed twice the input frame rate.
