正常人群印堂和准头部色诊中明度值对其主波长和兴奋纯度的影响

Influence of brightness value of supranasal point and apex nasi on dominant wavelength and excitation purity in complexion inspection of healthy adults

目的:通过检测正常人群面部印堂和准头部的可见反射光谱色度学数据,分析印堂和准头部位色诊的明度值对其主波长和兴奋纯度的影响。方法:应用光谱测色法采集516例正常人群印堂和准头部色诊的色度学参数,分别将印堂和准头部位的明度Y值与其色度的主波长和兴奋纯度进行线性相关性分析,以分析明度Y值对其主波长和兴奋纯度的影响。结果:正常人群印堂和准头部的明度Y值与其色度的主波长值无相关性;然而,明度Y值与其色度的兴奋纯度存在负相关。结论:色诊中明度Y值的大小不影响面部色诊的主波长值,表明肤色中偏白或偏黑不会对色诊光谱测色的主色调造成影响。然而,明度Y值与兴奋纯度有负相关性,其主色调的饱和度受到皮肤偏白或偏黑的影响,需要根据明度值的大小进行评价分析。本文结论为色诊参数的测量与结果分析提供了参考。

Objective： In this study, to analyze the influence of the brightness value of the supranasal point and the apex nasi on their dominant wavelength and excitation purity according to the spectrocolorimetry data of the supranasal point and the apex nasi in healthy adults that were collected based on optical spectrum colorimetry. Methods： A total of 516 healthy adults were taken as the research subjects. The brightness, dominant wavelength and excitation purity values of the supranasal point and the apex nasi during the complexion inspection of subjects were calculated. This was based on the visible reflection spectrum, and the linear correlation/regression analysis between the brightness Y value and the dominant wavelength or excitation purity value. Results： There was no correlation between the brightness Y value and the dominant wavelength of the normal supranasal point and the apex nasi; however, there was negative correlation between the brightness Y value and the excitation purity of the normal supranasal point and apex nasi. Conclusion： During the complexion inspection, the brightness Y value would not influence the dominant wavelength value, indicating that whiteness and/or blackness would not influence the normal individual complexion. However, the brightness Y value would influence the excitation purity of the supranasal point and the apex nasi, and the degree of saturation should be referred to as the brightness.
