In a video signal processing circuit, predetermined signal processes are executed to the signals Y, U, and V in which a ratio of sampling clocks is equal to (4:1:1) or (4:2:2). The signal Y is supplied to the mixing circuit through a delay adjusting circuit and the high frequency components are removed from the signals U and V by a band limiting filter and, after that, the resultant signals are supplied to the mixing circuit. The signal mixed by the mixing circuit is supplied to a LPF through a D/A converter. In the LPF, the signal is demodulated by the band limiting filter according to (4:4:4).

The first double rate conversion section inserts a first interpolation frame between a couple of successive original frames to output the original frames and the first interpolation frames. The second double rate conversion section generates a second and a third interpolation frames and allocates the second and the third interpolation frames between the couple of successive original frames to output the second and the third interpolation frames. The storage section stores the original frame and the first to the third interpolation frames. The quadruple rate conversion section sequentially reads out the original frame and the first to the third interpolation frames from the storage section in a quadruple rate to output the original frame and the first to the third interpolation frames.

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.
