In a method of generating a video pixel clock, a frequency of an output video pixel clock is increased to a first frequency setting when a quantity of data read from a frame buffer storing video data is greater than a reference level. The frequency of the output video pixel clock is decreased to a second frequency setting when the quantity of data read from the frame buffer is less than the reference level. Accordingly, an imbalance between frame rates of input and output image signals may be reduced.
