Image processing apparatus

Abstract

The image processing device comprises a receiving unit, a conversion unit, a correction unit and an inverse conversion unit. The receiving unit receives image data including a plurality of gray-scale values respectively corresponding to a plurality of sub-pixels of a panel. The panel includes a plurality of pixels arranged in an array, each pixel arranged in an odd-numbered column is composed of red, green and blue sub-pixels arranged in an inverted triangle, and each pixel arranged in an even-numbered column is composed of red, green and blue sub-pixels arranged in a regular triangle. The conversion unit converts each gray-scale value into a brightness value corresponding to each sub-pixel. And the correction unit calculates the correction brightness value of the target sub-pixel, so that the color cast phenomenon of the panel and / or the sawtooth phenomenon generated when the oblique line is displayed are / is improved. And the inverse conversion unit converts the corrected brightness value of the target sub-pixel into a corrected gray-scale value of the target sub-pixel.

Description

【Technical field】 [0001] The present invention relates to an image processing device, and more particularly, to an image processing device for improving the color shift phenomenon of a panel and / or the jaggies phenomenon generated when displaying oblique lines. 【Background technique】 [0002] A known sub-pixel configuration of a display panel with a triangular pattern is called a delta RGB panel. A deltaRGB panel includes a plurality of pixels arranged in an array, and each pixel is composed of three sub-pixels of different light-emitting colors arranged in a triangle. composition. However, the sub-pixel distribution of the delta RGB panel is discontinuous along the oblique direction, which causes the deltaRGB panel to produce a Slash Jaggy effect defect when displaying oblique lines. In addition, the delta RGB panel also suffers from the color shift effect. For example, when the delta RGB panel is used to display an image with white blocks on a black background, a reddish ...

AI Technical Summary

Problems solved by technology

However, the distribution of sub-pixels of the delta RGB panel is discontinuous along the oblique direction, which makes the deltaRGB panel produce the defect of Slash Jaggy effect when displaying oblique lines

In addition, the delta RGB panel also has the defect of color shift effect (color shift effect). For example, when the delta RGB panel is used to display an image with white blocks in a black background, a reddish color will appear on the left side of the white blocks. edge (reddish edge), and on the right side of the white block there will be a greenish edge (greenish edge)
