    • Flesh color pixels that constitute flesh color areas of a captured image are determined with respect to the three attributes of color: lightness, chroma and hue, and lightness-chroma distribution of the flesh color pixels is determined in a coordinate plane whose vertical and horizontal axes represent lightness and chroma respectively, and lightness-hue distribution of the flesh color pixels is determined in a coordinate plane whose vertical and horizontal axes represent lightness and hue respectively. Image data of the captured image is subjected to a color conversion process, so as partly to change the lightness-chroma distribution or the lightness-hue distribution of the flesh color pixels, to control color of the flesh color areas. For example, it is possible to raise chroma values or change hue of the flesh color pixels only in a high lightness zone.
    • 根据颜色的三个属性,亮度,色度和色相确定构成拍摄图像的肉色区域的肉色彩像素,并且在垂直和水平轴的坐标平面中确定肉色色素的亮度 - 色度分布 分别表示亮度和色度,并且在垂直和水平轴分别表示亮度和色调的坐标平面中确定肉色色像素的亮度色调分布。 对拍摄图像的图像数据进行颜色转换处理,以部分地改变肉色色像素的亮度色度分布或亮度色调分布,以控制肉色区域的颜色。 例如,可以仅在高亮度区域中提高肉色色像素的色度值或改变色调。
