PURPOSE: An apparatus for correcting synchronizing signal of a digital TV is provided to synchronize by correcting difference between an input synchronization and a display synchronization. CONSTITUTION: An image processing part(11) outputs an image according to a display clock and also outputs a display synchronization according to the display clock. A synchronization control signal generator like an NTSC PWM generator(12) generates a synchronization control signal for locking the display synchronization of an output image signal outputting from the image processing part(11) and synchronization of the image signal inputting through a bit stream. A synchronization signal correcting part corrects the synchronization signal of the image processing part(11) according to the synchronization control signal generated in the synchronization control signal generator. The synchronization signal correcting part corrects the synchronization signal for displaying by synchronizing the image signal inputting and the output image signal. Thereby, a stable analog image is outputted. |
