A control system includes a server, an active device and a passive device. An operation interface information is stored in the server. The active device is wirelessly connected with the passive device according to a communication identification information. When a device information of the passive device is acquired by the active device, a control application program of the active device retrieves the operation interface information from the server according to the device information. Consequently, an operation interface corresponding to the operation interface information is displayed on the active device. By operating the operation interface, the passive device is correspondingly controlled.

A facial tracking method for detecting and tracking at least one face image in a region during a time period. The facial tracking method includes a step of performing an image acquiring operation, a step of performing a facial detecting operation to detect whether there is any face image in the entire of a current photo image, and at least one step of performing a facial tracking operation. For performing the facial tracking operation, plural tracking frames are located around a face image of the current photo image, and a similarity between the face image of the current photo image and the image included in each tracking frame in order to judge whether the face image exists in the next photo image. By the facial tracking method of the present invention, the time period of tracking face images is largely reduced.

An image pickup system includes a base, a frame, an image pickup device, a receiving structure, a marking element and a switching element. The frame is connected to the base. The image pickup device is disposed on the frame. The receiving structure is disposed in the base. The frame is rotatable with respect to the base, so that the image pickup device is moved to an optimal shooting position. The marking element indicates that the image pickup device is at the optimal shooting position. When the switching element is triggered, the target object placed in the receiving structure will be shot by the image pickup device.

An image brightness adjusting method is provided. The brightness values of all pixels of the image are firstly increased in various increasing degrees. Next, the increased brightness values are decreased in various decreasing degrees according to the original brightness values, thereby avoiding over-increasing the brightness values of the image. Moreover, the use of the color saturation values to adjust the brightness values can avoid the unnatural image appearance.
