Gray level reproduction and dynamic false contour reduction on plasma display panel based on a single error diffusion

摘要

The present invention is a gray-scale reproduction and decision to an inverse gamma correction on the RGB input gray level of the current frame pixel (n) is input to the target gray-scale extraction of the contour reduction method in a plasma display panel (PDP) according to the single error diffuser outputs the target tone value to be represented by, converting the target tone values ​​received from the target tone extraction unit to the gradation of the actually displayable integer value in the round-off execution unit, the doctor determines whether the false contour generation pixel in the contour detection , by converting the present frame gray level value (n) in the tone value conversion unit to another gray level value, plasma displays on the display panel, the round-off execution unit and the gradation value converter output error the error diffusion between the parts when it is determined as a false contour generation pixel by average, representing the target gradation to propagate to the surrounding pixels to be processed in the next section, Is to output the image of the image quality improvement by the gray-scale representation and the false contour reduction by using the amount of calculation and memory.
