利用微小相对移动和计算机合成技术提高CCD等数字图像传感器分辨率是一个行之有效的方法．本文在这一技术的基础上，将CCD图像传感器按像元尺寸和不感光间隔尺寸二者之间的关系做出了分类，提出了适应更多图像传感器类型的高分辨率图像的获取方法和算法，并给出了某些类型的CCD图像传感器通过微位移方式提高分辨率的限度．计算机模拟和实验都验证了这种新方法的可行性．

It is an effective approach to improve CCD imaging resolution by micro-displacing CCD and reconstructing image in a computer. Based on this method,an assortment was proposed to differentiate CCDs by the relationship between pixel size and light-insensitive interval size. If the intervals are neglected,as usual,the quality of the reconstructed high-resolution image using the micro-displacing technology will be reduced,and some information of the original object might be lost. An algorithm which is available for more sorts of CCD is proposed to reconstruct high-resolution image,and the limitation of this approach is also educed. The simulation and experiment result show that the quality of the reconstructed image can be effectively improved.
