Abstract
An RGB signal to RGBY signal image converting method is disclosed and includes steps of: receiving RGB input signals Ri, Gi, Bi; determining whether a color of the RGB input signals is yellow; and calculating and outputting RGBY output signals Ro, Go, Bo, Yo when the color of the RGB input signals is not yellow, wherein Yo=0, RoGoBo=RiGiBi. An image converting system using the RGB signal to RGBY signal image converting method. The image converting method and system relatively increase a signal fidelity in converting the RGB signal to the RGBY signal.
