针对自主设计的一款CMOS图像传感器———CUST1089，如何实时、快速地调节其图像，设计了一种在线调试系统。该系统由PC机通过USB2I2C开发板访问CMOS图像传感器的寄存器，实现对图像的实时、快速的调整。在线调试系统由软硬件两部分组成，硬件部分利用I2C接口读写CMOS图像传感器的寄存器，软件部分不仅实现了DSP算法（增益、降噪、对比度、Gamma曲线校正等）手动调整寄存器参数功能，还实现了DSP算法自动生成相应的寄存器参数，完成对图像的自动调整，使图像质量接近真实场景。对于不同的CMOS图像传感器，该系统只需改变寄存器地址，即可完成对所有具有I2C接口的CMOS图像传感器的实时调节。

For a CMOS image sensor which was designed independently, CUST1089, how to adjust the image in the real-time and quickly, an online debugging system, which access registers of CMOS image sensor based on the USB interface and a USB2I2C chip, is described in this paper. The testing system includes both hardware and software parts. The hardware part uses the I2C bus interface to read and write the registers of CMOS image sensor, and the software part can not only realizes the manual adjustment function of DSP algorithm which includes gain noise contract Gamma curve correct, etc;also implements the DSP algorithm to automatically generate the corresponding register parameter, to carry out image automatic adjustment. And it can make the image close to the real scene. For different CMOS image sensor, only need to change register address, the system can complete adjustment all CMOS image sensor with I2C interface in real-time.
