Abstract
An automatic OSD adjusting device and the associated method are provided. The device includes a receiving unit, a processing unit, an OSD unit and an OSD adjusting module. The receiving unit receives a video signal. The processing unit is coupled to the receiving unit and processes the video signal to generate a pixel signal. The OSD unit generates an OSD signal. The OSD adjusting module, coupled to the processing unit and the OSD unit, compares the OSD signal with the pixel signal to generate a comparison result, and selectively adjusts the OSD signal according to the comparison result.
