不抬，一頭高；哈哈，你看看大頭在後麵

你引用的是3個單獨的Cone

 

按equal area cone sensitivity

In this type of display, the peak of each sensitivity curve is scaled up or down so that the area under each curve (equivalent to the total response sensitivity of each type of cone, pooled across all cones) is the same; these curves are usually presented on a linear vertical scale.

equal area cone sensitivity functions

the Stockman & Sharpe (2000) 10° cone fundamentals rescaled so that the area under each curve equals 10 on a linear scale

所有跟帖： 

• 您這是歸一化後的曲線。目的是三種錐細胞自己也自己比。它們之間的比較，還是得用上麵的圖。 -coolwin- ♀ (290 bytes) () 01/10/2016 postreply 14:02:01
