AI Technical Summary

Problems solved by technology

If the de-interlacing processing of the aforementioned video signal is carried out in units of fields or frames, it will often cause the problem of flickering (flicker) or jagged edges of these subtitles or logo patterns
It can be seen from this that the image processing method performed in units of fields or frames cannot meet the user's requirements for high-quality images.

Abstract

The invention provides a method for processing an image signal, a display method, and related devices. One method provided by the invention comprises the following steps of: performing the preset detection of the image signal; dividing a frame corresponding to the image signal into a plurality of regions, wherein each region comprises a plurality of pixels; and calculating statistical data with respect to the result of the preset detection of each of the plurality of regions respectively to obtain a plurality of statistical data corresponding to the plurality of regions.

Description

technical field [0001] The invention relates to image processing technology, in particular to an image signal processing method, a display method and related devices. Background technique [0002] In the prior art, image signal processing (such as calculation, statistics, or analysis of image displacement, pixel value distribution, etc.) is usually performed in units of field or frame. However, the image processing method performed in units of field or frame cannot take into account the differences between different regions in the image, thus often causing adverse effects on the image quality. [0003] For example, many existing display devices often add additional image data such as caption or logo to the video signal before displaying the video signal. These additional image data will only appear in a partial area of ​​the entire image frame. If the de-interlacing processing of the aforementioned video signal is performed in units of fields or frames, problems such as fl...
