Abstract
A video system suitable for being set in one of several scene modes and controlling one of several ambient light sources is disclosed. The video system includes a storage unit, a signal transceiver, and a control module. The storage unit stores several brightness setting values, in which the brightness setting values correspond to the scene modes and/or several specification data respectively, and the specification data is contained in the several ambient light sources respectively. The signal transceiver is used for receiving the specification data of one of the ambient light sources. The control module is electrically coupled to the signal transceiver, and controls the signal transceiver to transmit a corresponding brightness setting value in the storage unit to the ambient light source according to the set scene mode and the received specification data.
