| 中文摘要: |
| 实验比较数字移动终端和数码照相机在影像传感器缺陷、白平衡、动态范围、色彩还原、像面亮度均匀度、典型照度下成像性能方面的差异，并对实验数据进行处理分析，得出数字移动终端与数码照相机在成像质量方面的差异，为摄影艺术，特别是商业摄影提供技术借鉴。实验的检测方法主要参照《GB/T 29298—2012数字（码）照相机通用规范》和《YD/T 1607—2007数字移动终端图像及视频传输特性技术要求和测试方法》。实验结果表明，数字移动终端和数码照相机在白平衡、动态范围、色彩还原、典型照度下成像性能方面存在不同程度的差异。 |

| Testing of mobile phone cameras and digital still cameras was carried out in the aspects of image sensor fault,white balance,dynamic range,tint reducing power,center to corner zone ratio and imaging under model illumination.All testing shows that pictures taken by the mobile phone cameras and the digital still cameras are different.It is useful for camera industry.All test methods are subject to "Digital Still Camera General Specification" and "Technical Requirements and Test Methods for Visual Transmission Characteristics of Mobile Terminal".Based on the results of experiments,mobile phone cameras and digital still cameras get different pictures under the same condition.Especially in the aspects of white balance,dynamic range,tint reducing power,and imaging under model illumination,pictures taken by the two kinds of cameras are different. |
