The invention discloses an image exposure parameter adjusting method, equipment, and an image exposure parameter adjusting device. The image exposure adjusting method comprises the following steps: acquiring an image sequence; acquiring the image position information and the image brightness information of a current frame image; determining the area position information of a target area in the current frame image, and obtaining an area brightness statistical value of the target area according to the area position information and the image brightness information; determining a strong light areain the target area, and obtaining a corresponding strong light brightness statistical value; in combination with the brightness statistical value, the strong light brightness statistical value and the overall brightness statistical value of the target area, obtaining a current frame brightness value of the current frame image; and adjusting exposure parameters according to the current frame brightness value. According to the method, the target area is detected, the strong light area in the target area is identified, and dynamic weighting processing is performed on the target area, the stronglight area and the global brightness of the image, so that strong light in the target area is optimally suppressed, the influence of other interference light sources is eliminated, and the effect of the target area is best presented.
