| Abstract: | Invalid pixels have a great effect on the image quality of the infrared focal plane array device. In this paper, the definition of invalid pixel is presented firstly, and then the forming mechanism of invalid pixel is analyzed and the detecting methods for invalid pixel are discussed. With digital signal processing (DSP) chip, the hardware and software of infrared image processing system are designed for the purpose of auto-detection and correction of the invalid pixels. The experiment result indicates that the designed system get satisfied processing effect and the system meets the request of real-time and reliability. |
