Abstract:
The present invention discloses a multimedia device for processing a video signal and control method thereof. According to an embodiment of the present invention, the multimedia device includes a controller configured to perform tone mapping, a dynamic contrast function, and a local contrast function. The controller performs the tone mapping not only on an HDR video signal but also on an SDR video signal. When performing the tone mapping on the SDR video signal, the controller amplifies only an intermediate-gradient region without adjusting low-gradient and high-gradient regions. When performing the dynamic contrast function, the controller only an intermediate-gradient region of the video signal without adjusting low-gradient and high-gradient regions. When performing the local contrast function, the controller divides the video signal into blocks, calculates an APL value of each block, and then applies a linear curve based on the APL value.

Claim (Index 7):
The multimedia device of  claim 4 , wherein when performing the dynamic contrast function, the controller is configured to:\n output a fourth gradient region and a sixth gradient region of an original signal as it is; and apply a curve amplifying the original signal to a fifth gradient region, wherein the fourth to sixth regions do not overlap with each other, and wherein the fifth gradient region is a signal region higher than the fourth gradient region, and the sixth gradient region is a signal region higher than the fifth gradient region.
