数码相机是一种利用电子传感器把光学影像转换成电子数据的照相机,被称为数字相机。而曝光时间则是影像相机成像质量的重要参数之一。由于方法和设备缺失,数码照相机曝光时间没有统一的测试方法。本文通过分析数码相机曝光时间的相关概念,提出数码相机曝光时间测试方法,以期能给企业产品研发、质量控制提供参考。 Digital cameras are cameras that use electronic sensors to convert optical images to electronic data, called digital cameras. The exposure time is one of the important parameters of imaging quality of the image camera. Due to a lack of methods and equipment there is no uniform test method for digital camera exposure time. This paper analyzes the digital camera exposure time related concepts, proposed digital camera exposure time test method, with a view to enterprise product development, quality control provide a reference.
