数码相机的感光元件是相机的核心部位,是成像质量的关键影响因素。利用相机在不同条件下拍摄的照片,通过专业的图像处理软件分析照片的数据特点,并利用这些数据建立曝光量和灰度值之间的关系,对比分析不同相机、不同感光度等方面对感光特性曲线的影响。探讨了感光器件CMOS在不同条件下的感光规律。结果表明,利用数码相机拍照时应遵循多曝光不如少曝光的原则。
The sensor of the digital camera is the core part of the camera, it is the key influence factor of the imaging quality. Using the camera under different conditions to take photos, through professional image processing software to analyze the characteristics of the photo data, and use these data to establish the relationship between exposure and gray value, comparative analysis of different cameras, different sensitivities and so on Effect of the characteristic curve. The sensitivities of CMOS sensor under different conditions were discussed. The results show that the use of digital cameras should follow the principle of multiple exposure less exposure.
