On field sequential color (FSC) displays, a frame of an image is represented by sequentially displaying multiple fields. In the case of FSC LCD displays, color image is displayed by sequential control of backlights and modulation of light transmissions. Sequential displaying of multiple fields results in undesirable color artifacts near boundaries of moving objects. They are often called as color breakup (CBU). This paper presents a new method to measure perceived static CBU on natural color images. The proposed method can be utilized for performance evaluation or algorithm development for static CBU reduction.
