摘要： An image signal processing unit includes a frame rate conversion circuit performing double frame rate conversion on an input image signal from a first frame frequency to a second frame frequency. When performing frame rate conversion with the motion correction process, a motion vector is determined between a first frame image and a third frame image, and three interpolation frame images are formed through the motion correction process to the first frame image based on the motion vector, and are inserted between the first and third frame images so as to establish the second frame frequency. When performing frame rate conversion without the motion correction process, an interpolation frame image same as the first frame image is inserted between the first and second frame images, and an interpolation frame image same as the second frame image is inserted between the second and third frame images.

摘要： The present invention provides an image display apparatus capable of reducing a judder and simultaneously weakening the degree of reducing the judder at the time of converting frame rate of a film signal using motion compensation. At the time of converting frame rate of a video signal by adding N (N: integer of 2 or larger) interpolation frames into between original frames neighboring each other along time base obtained from video images in original frames by using motion compensation so that interpolation positions of the video images in the N interpolation frames are set to a deviated position which is closer to the nearest video image in the original frames rather than positions obtained by equally dividing, into (N+1) portions, magnitude of video image motion between an earlier original frame and a following original frame along the time base.

摘要： Viewing of a program is enabled at optimum image quality. A correspondence table of an image signal processing parameter and a combination of TMCC information and transmission errors is stored in a RAM. A CPU reads out an image signal processing parameter corresponding to a combination of TMCC information supplied from an IF demodulator and transmission errors supplied from the IF demodulator, a demultiplexer and an MPEG video decoder from the correspondence table stored in the RAM, and controls signal processing in an image signal processing portion and display processing in an image display portion based on the image signal processing parameter.

摘要： The invention provides an image processing apparatus and method as well as a providing medium by which deterioration of the vertical resolution is prevented and conspicuous appearance of line flickering is suppressed. In order to convert an interlaced video signal having 525 scanning lines into another progressive video signal having 525 scanning lines while maintaining the image size, in an odd-numbered field, a line after conversion is offset by 0.5 H (H is the distance between horizontal scanning lines of the inputted video signal). Consequently, pixel data of each line Oi are produced from pixel data of two lines Ii and Ii+1 before conversion. As a result, pixels of a line on the boundary between white pixels and black pixels have a gray color. In an odd-numbered field, no offset is given, and pixel data of each line I1 of the field before conversion are set as they are as pixel data of each line Oi of the field after conversion. The pixels of the line on the boundary between the white and black pixels become white or gray pixels, and consequently, when compared with an alternative case wherein such pixels on the boundary line are white and black pixels, line flickering is prevented from being observed conspicuously on a display screen.
