Abstract:
Disclosed are method for improving image effect and apparatus thereof, comprising: when a system starts up, acquiring a screen parameter to determine whether an input signal source is an SDR film source or an HDR film source; if it is an SDR film source, performing first image processing to obtain an SDR image, starting up HDR conversion mode; reducing its backlight brightness to pre-set brightness, and displaying current peak brightness pixel or area according to a screen parameter after increasing backlight brightness; if it is HDR film source, performing second image processing to obtain HDR image, closing down HDR conversion mode, before displaying. Thus, a high-grayscale detail performance capacity is improved, achieving an SDR-to-HDR function, a higher brightness range, more picture details, an SDR film source can be played in an HDR television with the display effect of an HDR film source.

Claim (Index 1):
A method for improving an image effect, wherein comprising a plurality of following steps: when a system starts up, acquiring a screen parameter to determine whether an input signal source is an SDR film source or an HDR film source; if the input signal source is an SDR film source, performing first image processing on the SDR film source to obtain an SDR image, and starting up an HDR conversion mode; reducing a backlight brightness of the SDR image to a pre-set brightness, and displaying a current peak brightness pixel or a peak brightness zone according to the screen parameter after a backlight brightness is increased; and if the input signal source is an HDR film source, performing second image processing on the HDR film source to obtain an HDR image, and displaying the HDR image after closing down the HDR conversion mode.
