Method and device for converting Pentile images into RGB images, and storage medium

Abstract

The embodiment of the invention discloses a method and device for converting Pentile images into RGB images, and a storage medium, and is used for converting Pentile images into RGB images. The method provided by the embodiment of the invention comprises the following steps: acquiring pixel positions and pixel values of all pixel points on a Pentile image; determining a first initial phase, a second initial phase, and a step value according to Pentile type information of a Pentile image; determining an R pixel point group on the Pentile image; generating N R new pixel points by using an interpolation algorithm and according to the first initial phase, the step value, and the pixel positions and the pixel values of the R pixel point group; determining a B pixel point group on the Pentile image; generating N B new pixel points by using the interpolation algorithm according to the second initial phase, the step value, and pixel position and pixel values of the B pixel point group; generating N RGB pixel points according to pixel positions and pixel values of G pixel points, the N R new pixel points and the N B new pixel points; generating an RGB conversion image according to the N RGB pixel points.

Description

technical field [0001] The embodiments of the present application relate to the field of image processing, and in particular to a method, device and storage medium for converting a Pentile image into an RGB image. Background technique [0002] The traditional RGB array image is composed of three sub-pixels of red, green and blue, but the single pixel of the Pentile array image is different, one is red and green, and the other is blue and green. We know that only three primary colors can form all colors, but two colors cannot form all colors, so when actually displaying an image, one pixel of the Pentile array image will "borrow" the other pixels adjacent to it One color to form the three primary colors. In the horizontal direction, each pixel shares the sub-pixel of the color it does not have with its adjacent pixels to achieve white display together. Appearance comparison between the Pentile array image and the traditional RGB array image: the three primary colors of the ...

Problems solved by technology

[0004] However, on the Pentile array image, the distribution of pixels in the Pentile array image of different manufacturers is also different, please refer to figure 1 , figure 2 , image 3 and Figure 4 , the relative positions of the RGB pixels on the Pentile array image in the figure are very different, that is, there is a big difference in the distribution form of the RGB pixels

Moreover, Pentile array images in different distribution forms will improve the yield rate of OLED screens by reducing the number of sub-pixels per Pixel, but at the expense of image resolution

In particular, in this format, the three-channel sub-pixels of the RGB image are no longer regularly arranged, which makes it impossible to convert from the Pentile image to the RGB image when the RGB display receives the Pentile image.
