提出了一种新的电荷耦合器件（CCD）图像处理方法，该方法基于片上像素合并和从单个传感器曝光产生多个输出图像信号。输出图像因分辨率、信噪比和传感器像素区域而异。该方法的结果在减少帧读出时间和增加的信号噪声比的空间分辨率的贸易。当在低光成像条件下使用时，应执行输出信号校正。提出了基于CCD摄像机标定的校正方法。实验方法的实施与高分辨率CCD显示沿着与相应的结果。
A new method for charge-coupled device (CCD) image processing is presented, based on on-chip pixel binning and generation of several output image signals from a single sensor exposure. Output images differ by resolution, signal-to-noise ratio and sensor pixels region. The method results in reduced frame readout time and increased signal-to-noise ratio in trade for spatial resolution. When used in low-light imaging conditions the output signal correction should be performed. The correction procedure based on CCD camera calibration is presented. Experimental method implementation with high-resolution CCD is shown along with corresponding results.
