A method of controlling a display device is disclosed including receiving a plurality of sub-pixel values for a target pixel among a plurality of pixels of an image frame, wherein the sub-pixel values of the target pixel comprise red, green, and blue sub-pixel values; calculating a pixel-based boosting ratio corresponding to the target pixel according to the sub-pixel values of the target pixel; and adjusting at least one of a plurality of backlight duties associated with the target pixel and the plurality of sub-pixel values of the target pixel according to the pixel-based boosting ratio.

Method and electronic device for controlling display device based on color perceived brightness

A method is provided for reconstructing a high dynamic range (HDR) video from a low dynamic range (LDR) video. The LDR video is captured with dynamic exposure values by a regular camera device to store as an LDR video file. An exposure setting sequence and an LDR video frame sequence are retrieved from the LDR video file, where the exposure setting sequence corresponds to the LDR video frame sequence. The LDR video frame sequence is aligned to generate a compensated frame sequence to merge with the LDR video frame sequence, so as to generate an HDR frame sequence and reconstruct the HDR video.
