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 10):
An apparatus for improving an image effect, applied to achieving the method for improving the image effect according to  claim 1 , connecting to a displayer, wherein comprising a main chip, a signal board, a T-CON board and a constant current drive circuit; when a system starts up, the main chip acquires the 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, the main chip performs first image processing on the SDR film source to obtain an SDR image, and controls the T-CON board start up an HDR conversion mode through the signal board; the T-CON board controls the constant current drive circuit reduce the backlight brightness of the SDR image to the pre-set brightness, and transfer a current peak brightness pixel or a peak brightness zone to the displayer for display, after the backlight brightness is increased according to the screen parameter; and if the input signal source is an HDR film source, the main chip performs second image processing on the HDR film source to obtain an HDR image, and controls the T-CON board close down the HDR conversion mode through the signal board; the T-CON board controls the constant current drive circuit transfer the HDR image to the displayer for display.
