A distortion module (5) reduces the luminance of a backlight source according to the histogram of the video signal so that the contrast may be a predetermined target one. A configuration design unit (13) sets the gain according to the luminance level (BLreduced) of the backlight source selected by the distortion module (5). When setting the gain, the luminance level (BLref) for reference of the backlight source preset according to the video feature value is referenced. If the video feature value meets a predetermined condition, the input video signal is always amplified with the gain. If not, depending on the relation between the BLreduced and the BLref, the input video signal is amplified or not."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Video display apparatus for adjusting the degree of amplification of the input image according to image characteristics","description":"Brightness expression without solid white pattern is enabled, and video expression with an improved black level is achieved.
