A method and apparatus for reducing the video image luminance osd

The present invention discloses a kind of OSD video image to reduce the brightness of the method, the method is: the OSD video image to reduce the brightness of the method comprising: determining whether there is an image frame containing the OSD video signal; when present in the video signal containing OSD image frame, said image frame and a position corresponding OSD luminance value is determined; and the position and the luminance value of the corresponding OSD image frame, the video signal is reduced significantly when the weight of the OSD display image frame brightness. The present invention also discloses a kind of OSD video image to reduce the brightness of the device. Method and apparatus for reducing the luminance of the OSD video image provided by the invention can be achieved in the video signal other than the OSD image display brightness kept constant premise of reducing the display brightness of the OSD, to ensure that the user watches the video program containing the OSD when visual comfort, enhance the user experience visual effects.
