Abstract:
1. A synchronization control apparatus for driving a display module in an interlaced scan mode, the synchronization control apparatus comprising: a delay circuit for delaying an input vertical sync (IVS) signal to generate a delayed signal; a first multiplexer coupled to the delay circuit for selecting one of the IVS signal and the delayed signal according to an odd/even field indication signal to generate an output vertical sync (OVS) signal; a second multiplexer coupled to the first multiplexer for selecting one of a first data corresponding to a first function and a second data corresponding to a second function as a third data according to the odd/even field indication signal; and a convolution circuit coupled to the second multiplexer for performing a convolution operation according to an input video data and the third data to generate an output video data to be utilized for driving the display module.
