颜色视觉是入眼受到不同波长的光线刺激时,产生的一种心理物理现象.没有视觉系统(包括外周及中枢等各部)的功能,光波就只有波长之分,而无颜色之别.人眼的色觉特性一定波长产生一定颜色视觉.人眼对可见光谱中不同波长的光线刺激,主要可辨别出七种颜色:红、橙、黄、绿、青、蓝、紫.每种颜色视觉均有对应的一段刺激光谱,若用全部可见光谱同时照射人眼,则为白光;若用全部可见光谱照在一个物体上,物体的色素将大部分光线吸收掉,只反射出一
Color vision is a kind of psychological and physical phenomenon that occurs when the eyes are stimulated by light of different wavelengths.Without the function of the visual system (including the peripheral and central departments), the light waves are only divided in wavelength but not in color. Color vision characteristics of a certain wavelength to produce a certain color vision. The human eye on the visible spectrum of different wavelengths of light stimulation, the main discernible seven colors: red, orange, yellow, green, blue, purple. Each color vision has a corresponding Of the stimulus spectrum, if the entire visible spectrum at the same time illuminate the human eye, the white light; if the entire visible spectrum is illuminated on an object, the object of the pigment absorbs most of the light, only reflects a
