Pixel interpolation technology used for high-definition image display

Abstract

The invention provides a pixel interpolation technology used for high-definition image display. A method of increasing pixel display density is used for effectively solving the problems that when the eyes of the human body watch an LED image at short range, edges are rough, and definition and resolution are not insufficient. The definition of the image is improved. The pixel interpolation technology includes space interpolation, time interpolation and primary color scanning interpolation. The space interpolation is that adjacent pixels of the image are arrayed on space in a scattering mode, the pixels of adjacent ranks are arrayed in the space at intervals in a one-row or multi-row mode or in a one-column or multi-column mode, the difference between perpendicular positions is Deltah, and the difference between horizontal positions is Delta s. The time interpolation is that through control over scanning time, the pixels arranged in the space at intervals in the movement are sequentially driven in a time-delay mode, so that the pixels are combined into one row or one column. The three primary color scanning interpolation is that the R, G and B primary color pixels are arrayed in the space to ensure that the R, G and B sequentially have leaning angles so that scanning lines of each color can be evenly filled into a display area, overlapping and loss of the scanning lines are avoided, and therefore the row resolution ratio and brightness evenness of the image are improved.

Description

technical field [0001] The invention relates to the technical field of follow-up vision applications, in particular to a pixel interpolation technology for high-definition image display, which can be applied to rotating advertisements and lighting decorations in tunnels and subways. Background technique [0002] Advertising is a very important business field. People use advertisements to know companies, shape corporate images, build brands, and display products. Advertising displays and display systems installed in roads, tunnels and other commercial areas have become a part of people's lives. the part that can not be lost. The display system currently used on most billboards is either a printed cloth or a display system composed of an LED array. Printed cloth is gradually becoming obsolete due to its single display and inability to achieve dynamic effects. [0003] Due to the large LED pixel particles, when the human eye watches the LED image at close range, the edges are...
