Abstract
A synchronization control device for use in a TV system is provided. The TV system includes a TV and a first electronic device. The synchronization control device includes: a microcontroller; a first detection apparatus, and a second detection apparatus. The synchronization control device is capable of detecting the power state of the TV and of the first electronic device using color image sensors to detect the status of power indicators of the TV and of the first electronic device. When the power state of the TV is different from that of the first electronic device, the microcontroller controls a first infrared emitter in the first detection apparatus to emit a infrared control signal to the TV to switch the power state of the TV, so that the power state of the TV is synchronized to the power state of the first electronic device.
