              The PAL video standard adopted in China is defined as 25 frames per second (the interval between frames is 40 milliseconds). If the camera lens's depth of field (image clear range) is 1 meters. For the speed of 90 km / h (0.001*3600/0.04=90), the camera can only collect 1 frames of clear pictures. In order to get more clear images, we should try to increase the depth of field, the specific method is to increase the lens, reduce the full size of the CCD camera.
