Embodiment Construction
[0047] The basic idea of the present invention is: a signal processing system of a variable spectrum multispectral camera based on an area array CCD is proposed, including a variable spectrum timing controller, a drive circuit, and a frame transfer area array CCD with the function of pouring charges , analog-to-digital conversion circuit and video processor. The variable spectrum timing controller generates the timing signal used to drive the area array CCD to work according to the specified spectrum; the driving circuit converts the timing signal into the driving signal of the corresponding amplitude; the frame transfer area array CCD with the function of dumping charges Under the action of the output spectrum information; the analog-to-digital conversion circuit converts the analog signal output by the CCD into a digital signal; the video processor receives the digital image signal and processes the image information according to the input parameter requirements.
