Abstract
Provided are a method and device for image conversion from RGB signals to RGBW signals. The method includes the steps of converting RGB input signals as received into corresponding RGB luminance input values respectively; determining RGBW luminance output values respectively according to a position relationship between a corresponding point of the RGB luminance input values and regions divided by RGBW in a chromaticity diagram; and converting the determined RGBW luminance output values into corresponding RGBW output signals respectively and outputting the RGBW output signals.
