ELECTRONIC DEVICE AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/054927
Kind Code:
A1
Abstract:
Disclosed is an electronic device. The electronic device comprises: a storage storing first human visual system (HVS) recognition information according to a difference in brightness between adjacent pixels based on a first maximum output brightness and second HVS recognition information according to a difference in brightness between the adjacent pixels based on a second maximum output brightness; and a processor for obtaining a first histogram regarding a difference in gradation between adjacent pixels of an input image on the basis of the first maximum output brightness, obtaining a second histogram regarding a difference in gradation between the adjacent pixels of the input image on the basis of the second maximum output brightness, obtaining a third histogram regarding a difference in brightness between the adjacent pixels of the input image on the basis of the first HVS recognition information, obtaining a fourth histogram regarding a difference in brightness between the adjacent pixels of the input image on the basis of the second HVS recognition information, and obtaining a brightness value regarding the input image corresponding to the second maximum output brightness on the basis of a difference between a first value obtained on the basis of information on the first and third histograms and a second value obtained on the basis of the second and fourth histograms.
