Abstract: An automatic adjusting method for equipment and a smart adjusting device using the same are provided. The automatic adjusting method of the equipment includes the following steps. A template frame from the equipment is obtained in an initial period. Several clear frames are obtained in one window period. Each of the template frame and the clear frame has a pixel variation. The pixel variation of the template frame is the largest in the initial period. The pixel variation of each of the clear frame is greater than a threshold. Each of the clear frame is compared with the template frame to obtain an offset. A statistical value of the offsets is calculated. A parameter of the equipment is adjusted to reduce the statistical value.
