Abstract:
1. A display device with playback functionality, adapted for reproducing image information recorded in a storage medium, said display device comprising: an image information extracting module for extracting the image information from the storage medium, and processing the image information so as to generate and output a first setting image signal that conforms with a specific format; an image processor coupled electrically to said image information extracting module for receiving said first setting image signal and performing picture quality processing on said first setting image signal so as to generate and output a second setting image signal that conforms with said specific format; a display unit coupled electrically and respectively to said image processor and said image information extracting module, and capable of receiving and displaying one of said first and second setting image signals conforming with said specific format; and a control unit coupled electrically to said image processor and adapted for receiving a command, for performing control such that said display unit receives one of said first and second setting image signals directly when said command is received, and such that said display unit receives the other of said first and second setting image signals when said command is not received; wherein said command is a picture quality activation command; wherein, when said control unit does not receive said picture quality activation command, said control unit deactivates said image processor and performs control to enable said display unit to receive said first setting image signal from said image information extracting module, and when said control unit receives said picture quality activation command, said control unit activates said image processor and performs control to enable said display unit to receive said second setting image signal from said image processor; wherein a waiting period pending activation of said image processor is eliminated; and wherein power utilized for activating said image processor is saved and a start-up time of said display device is reduced.
