Abstract:
An electronic device and an image conversion method of the electronic device, the electronic device comprising: a receiving unit for receiving a first image from a source device; a decoding unit for decoding brightness information of the first image; a converting unit for converting a dynamic range of the first image on the basis of the decoded brightness information, using a mapping function; and a display unit for displaying a second image having the converted dynamic range on a display, wherein the mapping function is a curve function including a plurality of points determined on the basis of the first image, a characteristic of a change in brightness of a display of the source device, and a characteristic of brightness of a scene of the first image. The present disclosure may generate, for example, a high dynamic range (HDR) image, which is improved from a standard dynamic range (SDR) image.

Claim (Index 8):
The electronic device as claimed in  claim 7 , wherein the mapping function is [ R out G out B out ] = ( w \u00b7 [ R i \ue89e \ue89e n G i \ue89e \ue89e n B i \ue89e \ue89e n ] ) , where w is f(Yin)/Yin, which is a gain value obtained from the mapping function, and f(x) is an inverse Tone Mapping function (iTM), and Yin is a luminance value of the first image, and (Rin, Gin, Bin) is RGB coordinates of a white level of a first image, and (Rout, Gout, Bout) are RGB coordinates of a white level of a display on which a converted image is displayed.
