摘　　要：针对当前图像传感器的曝光控制技术不足,为了提高图像的质量,提出一种改进的滚筒式图像传感器曝光控制技术。阐述了当前图像传感器曝光控制研究现状,指出了传统滚筒式图像传感器曝光技术的局限性,并对其进行相应的改进,结果表明,此技术可以提高图像传感器曝光时间的控制精度,拓宽了图像动态范围,具有一定的实际应用价值。In view of exposure control technology defects for the current image sensor, in order to improve the quality of image, a new method to improve the image quality of the image sensor is proposed in this paper. This paper expounds the current situation of research on exposure control of mage sensor and points out the limitation of the traditional drum type image sensor exposure technology, and makes the corresponding improvement. The experimental resuits show that the proposed technology can improve the control precision and the exposure time of the image sensor, broaden the dynamic range of the image, and has a certain practical application value.
