For full‐color e‐paper displays that have a small color gamut, we improve distorted image tones in high‐saturation regions using saturation‐based tone‐mapping curves derived from measured chroma‐saturation characteristic. The improvements are experimentally verified via several test charts and natural images. More important, the method can adapt to varying ambient light.
