VIDEO PROCESSING APPARATUS AND VIDEO PROCESSING METHOD
First Claim
1. A video processing apparatus comprising:
- a signal processing part to process an inputted video signal;
a display panel to display the video signal processed by the signal processing part;
a backlight unit comprising a plurality of light emitting elements that correspond to pixels of the processed video signal and emit light to the display panel; and
a controller to calculate a brightness of each of the pixels based on R, G, and B component values of each of the pixels of the video signal processed by the signal processing part, and to control the backlight unit such that the plurality of light emitting elements emit light with intensities corresponding to the calculated brightness of each of the pixels.
