摘　　要：在测试实验中引入了色差和均方根误差的概念,来评价尼康D700数码单反相机的颜色还原性能,并使用分界曝光的方法测试了相机的宽容度。通过实验分析发现,相机的宽容度为8.3 EV,在颜色还原方面,相机再现红色和绿色能力较差。根据测试实验所反映的问题,有助于在后续的图像采集过程中做出相应的调整,降低拍摄对颜色带来的影响。The concept of color difference and the root mean square error was introduced into the test to evaluate the Nikon D700 digital SLR camera color reproduction performance.Boundary exposure method was applied to test the camera＇s tolerance.It was found that the tolerance of the camera is 8.3 EV;the camera has lower reproduction ability for red and green.The problems found in the experiment are helpful in making corresponding adjustment in following image collection process to reduce influence of shooting.
