Abstract:
1. A display apparatus comprising: a signal input unit through which an image signal is input, the image signal comprising a horizontal synchronization signal and an active signal; an adjustment signal generating unit that generates an adjustment signal; a signal processing unit that receives the adjustment signal and adjusts the image signal based on the adjustment signal; and a controller which analyzes the input signal and controls the adjustment signal generating unit to adjust characteristics of the adjustment signal if the controller determines that at least a portion of the adjustment signal would not lie within a blanking interval between the horizontal synchronization signal and the active signal, wherein the controller changes a reference of time for generating the adjustment signal from a falling edge of the horizontal synchronization signal to a rising edge of the horizontal synchronization signal if the controller determines that at least the portion of the adjustment signal would not lie within the blanking interval between the horizontal synchronization signal and the active signal.
