概括
光源的颜色温度显著影响红肉颜色测量. 使用D50 (5000K) 照明,而不是D65 (6500K),更好地保持肉的天然红色外观,以进行准确的评估.
科学领域:
- 食品科学 食品科学 食品科学
- 测色仪的颜色测量方法
- 图像处理 图像处理
背景情况:
- 准确的红肉颜色评估对于消费者认知和购买决策至关重要.
- 图像处理系统 (IPS) 越来越多地用于客观色彩分析.
- 照明条件,特别是相关色温 (CCT) 对肉色度指标的影响需要进一步研究.
研究的目的:
- 调查光源变化的相关色温 (CCT) 对红肉关键颜色参数的影响.
- 使用图像处理系统确定最佳的CCT,以保持肉类的天然红色外观.
- 为肉类颜色评估中标准化照明提供实用见解.
主要方法:
- 红肉样本使用图像处理系统 (IPS) 进行分析.
- 使用可调节的LED照明,CCT范围从2900K到7800K,保持一致的照明强度和高颜色染指数 (CRI>95).
- 测量了颜色参数,包括亮度 (L*),红度 (a*),黄度 (b*),色度 (C*),色调角度和红度指数.
主要成果:
- 轻度 (L*) 值在不同的CCT中在统计学上保持不变 (p > 0.05).
- 红度 (a*) 和黄度 (b*) 值受到CCT (p < 0.05) 的显著影响,a*在5100 K达到峰值,b*在6900 K以上急剧增加.
- 色角度从5100K显著增加到7200K,表明向黄色棕色调的转变;色彩 (C*) 没有显著变化 (p > 0.05).
结论:
- 相关色温 (CCT) 显著影响红肉的客观色彩测量,影响感知到的红色和色调.
- 建议在D65 (6500K) 上使用D50 (5000K) 的照明,以便更准确地评估红肉的自然颜色.
- 标准化照明条件对于使用图像处理系统在肉类工业中获得可靠的颜色数据至关重要.

Color Vision
1.3K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Changes in Skin Color: Clinical Perspectives
3.3K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
