摘要:
A noise reduction method for reducing noise in an input video signal to output an output video signal includes the steps of generating a motion-compensated reference video signal from the output video signal; delaying the output video signal to generate a non-motion-compensated reference video signal; mixing the motion-compensated reference video signal with the non-motion-compensated reference video signal to generate a reference video signal; subtracting the generated reference video signal from the input video signal to generate a differential signal; compensating the differential signal to generate a noise reduction signal; and subtracting the noise reduction signal from the input video signal.

A flat display panel such as an FED panel is provided in which high display luminance is obtained with high picture quality and a simple wiring structure. A display device includes a display panel in which column direction wirings 15 and row direction wirings 16 are formed perpendicularly to each other and the column direction wirings 15 are divided into N sets (N is an integer of 2 or more) in the vertical direction of a screen, drive elements 13, 18 which drive each of these N sets of the column direction wirings 15, a scanning element 14 which scans the row direction wirings 16, and an interpolation element 19 which performs flame-interpolation on an input video signal N times; wherein the scanning element 14 simultaneously scans the row direction wirings 16 corresponding to these N sets of the column direction wirings 15 respectively with approximately 1/N the vertical cycle of the video signal, and the drive elements 13, 18, to which an interpolated video signal from the interpolation element 19 is input, drive each of these N sets of the column direction wirings 15 by the interpolated video signal with a frame shifted by 1/N the vertical cycle of the input video signal.

While the memory amount is reduced through minimizing correction data prepared in advance, the capability of uniformity correction can be improved, compared to a related art. Correction data for correcting display unevenness between pixels for representative pixel points is stored. Correction data for pixels except for the representative pixel points is calculated by interpolation. The representative pixel points are arranged with a higher density in a pixel region with relatively finer display unevenness.
