A method for reducing a flicker is provided to adjust a pixel clock signal when shutter speed is faster than a preset threshold value, thereby synchronizing the adjusted pixel clock signal with a horizontal synchronization signal. An image signal processor detects illuminance of image light which is incident through an image sensor(S31). When illuminance is high, the image signal processor receives a smaller amount of light by quickly adjusting shutter speed(S32). The image signal processor determines whether the adjusted shutter speed is faster than a preset shutter speed threshold value(S33). When the shutter speed is faster than the preset shutter speed threshold value, the image signal processor adjusts a blank interval of the pixel clock signal until a pixel clock signal is matched with the horizontal synchronization signal(S34,S35). |
