An image display system including an image display device and a remote control is provided. The image display device used for displaying image includes a wireless receiving module, a driving unit and a controlling unit. The remote control includes an adjusting unit and a wireless transmitting module. The adjusting unit is used for adjusting an orientation of displaying face of the image display device. When an adjusting unit acts, the wireless transmitting module converts the corresponding operation signal into a wireless signal and outputs the wireless signal to a wireless receiving module. The wireless receiving module receives and converts the wireless signal into an electric signal, and then outputs the electric signal. The controlling unit controls the driving unit for driving the displaying device to rotate according to the electric signal.

A karaoke apparatus and the method thereof are provided, which guarantees the pitch of the karaoke music conforms to the pitch of the user. The apparatus comprises an audio input unit, a scale detector, a memory unit, a processor and a scale control unit. The audio input unit receives a test sound. The scale detector analyzes at least one test step of the test sound. The memory unit stores a plurality of standard steps. The processor finds out the highest step among the test steps, compares the highest step with the standard steps, and obtains a target step from the comparison; wherein, the target step is the standard step closest to the highest step. Finally, the scale control unit adjusts the pitch of the karaoke music so that the pitch is lower than that of the target step.

A display system includes a remote control and a display apparatus. The remote control includes a photo sensor, a particular button and a wireless transmitting module. The display apparatus includes a screen, a wireless receiving module and a microprocessor. When the particular button is triggered, the photo sensor senses a brightness of the environment in which the remote control is located, and then an environment brightness value is generated accordingly. The wireless transmitting module outputs the environment brightness value to the wireless receiving module by wireless transmission. The wireless receiving module outputs the environment brightness value to the microprocessor. The microprocessor adjusts a display brightness of the screen according to the environment brightness value.
