For example, referring to FIG. 3A, when the driver rotates the steering wheel to the left, the sensor 111 outputs a left-turning steering wheel rotation signal to the first transmission interface 113, and the first transmission interface 113 will output a direction. The left-turning steering wheel rotates the signal to the second transmission interface 131. At this time, the image sensor captures a row of vehicle images 170, and the image processor 135 divides the driving image 170 into a plurality of sub-images 171, 172, and Each of the sub-screens 171 and 172 corresponds to a preset rotation angle value.
