Abstract
A method for controlling an electronic apparatus includes determining representative colors of pixels of a received image frame; calculating input dynamic ranges for respective representative colors based on brightness information of the received image frame; expanding a dynamic range for the representative colors based on at least one of the brightness information of the received image frame and display characteristics of the electronic apparatus; and outputting an image frame having adjusted brightness based on the expanded dynamic range.
Claims23
A method for controlling an electronic apparatus, the method comprising:
- determining representative colors of pixels of an image frame;
- calculating input dynamic range for each of the representative colors based on brightness information of the image frame;
- expanding the input dynamic range for each of the representative colors based on the brightness information of the image frame and display characteristics of the electronic apparatus;
- and
- outputting an image frame of which brightness is adjusted based on the expanded dynamic range.
An electronic apparatus comprising:
- a receiver configured to receive an image frame;
- a representative color determiner configured to determine representative colors of pixels of the received image frame;
- an input dynamic range calculator configured to calculate input dynamic range for each of the representative colors based on brightness information of the received image frame;
- a dynamic range expander configured to expand the input dynamic range for each of the representative colors based on the brightness information of the received image frame and display characteristics of the electronic apparatus;
- and
- an output unit configured to output the image frame of which brightness is adjusted based on the expanded dynamic range.
An apparatus comprising:
- a receiver configured to receive an input image frame having pixels;
- a processor configured to determine representative colors of the pixels of the received image frame, calculate input dynamic range for each of the representative colors based on brightness information of the received image frame, and expand the input dynamic range for said each of the representative colors based on the brightness information of the image frame and display characteristics of the apparatus;
- and
- a display configured to output an output image frame of which brightness is adjusted based on the expanded dynamic ranges.
