In order to improve the image quality of a high speed airborne Time Delay and Integration Charge Coupled Device (TDICCD) camera, a method to precisely adjust the Correlated Double Sample (CDS) signals is proposed. Moreover, a method to compensate the temperature excursion of the driver is proposed. First, the principle of CDS is introduced, and the influence of sample position on a TDICCD camera is analyzed. Then, a method is proposed to adjust the sample signals precisely, which is based on the MUXCY in FPGA. At the same time, the effect of temperature excursion of the driver on TDICCD signal is analyzed, and an adaptive method is proposed to compensate the temperature excursion, which could satisfy the sample timing relationship. Experiments were made from two aspects, which were based on the TDICCD imaging system in our project. One is aimed to the effect of the precision of sample position on imaging quality, and the other is aimed to temperature. Experiment results show that the methods proposed can adjust the sample position precisely, which can improve the dynamic range of an image, and adapt the temperature excursion of the driver. Before compensation, the signal and noise ratio of the image acquired at -36℃ is 37.4 dB. After compensation, the signal and noise ratio of the image acquired at -36℃ is 51 dB.
