Abstract

The invention discloses a high definition television (HDTV) super processor and processing method, adopting digital separation technique to separate Y / C signal, realizing programmable processing, and making the processing more thorough without any regulation. The invention also adopts 3D comb filter and can determine to adopt 2D comb filter, time comb filter or the mixture of them according to whether pixels move or not, thus further improving the image, and for the static image, its color error is zero. The invention also adopts 3D self-adapting noise reducing technique, interleaving to non-interleaving technique, motion compensating technique, frame-frame interpolation technique, film mode processing, black level extension, blue level extension, gama-correction technique, color and brightness improving technique, etc, and can make arbitrary frame frequency and line frequency conversion, and make frame-frame interpolation according to motion characteristic of the image, keeping the continuity of the converted image and making the image bright, clear and smooth.

Description

【Technical field】: [0001] The invention relates to a high-definition television super processor and a method. 【Background technique】: [0002] In our country and even in the vast majority of countries in the world, analog signals are used as the main transmission carrier for TV stations, and the TV sets used should also belong to analog TV sets. The disadvantages of this type of TV are: the brightness and chrominance signals cannot be completely separated, and the crosstalk phenomenon is serious, which is one of the main reasons for the decline in image quality; flicker between lines, large-area image flicker, apparent parallel or real parallel phenomenon, Jagged vertical edges, crawling effect. At present, the PAL system adopted by my country's TV system belongs to analog TV broadcasting. [0003] At present, the three major TV standards in the world, NTSC, RAL, and SECAM, are systems for analog processing and transmission of analog TV signals. In order to save transmiss...
