In some fields such as scout and military affairs, TV camera main illumination parameters must be calibrated in order to acquire accurate results. This paper presents the design and implementation scheme of an integrative testing system for main illumination parameters of TV cameras based on video signals processing. Special testing targets were used for video imaging. The image sequences output of the camera are captured using a high accuracy frame grabber and the extracted data are stored in a computer. After the measurement, the TV camera main illu-mination parameters, such as liner response, dark illumination, SNR, dynamic range and TV resolution, distortion, and contrast are extracted and automatically calculated by means of the digital video image processing program.
