Image display device, image display method, and program
View Patent ↗Provided is an image display device including a high frame rate signal generating unit ( 20 ) that increases a frame rate of an input video signal, a frame rate adjusting unit ( 30 ) that adjusts a frame rate by setting a non-emission frame at a predetermined cycle on a high frame rate video signal output from the high frame rate signal generating unit ( 20 ), and a display panel ( 40 ) that displays a video based on a video signal output from the frame rate adjusting unit ( 30 ).
1. An image display device, comprising:
circuitry configured to:
generate a high frame rate video signal by increasing a frame rate of an input video signal;
set a non-emission frame at a predetermined cycle on the high frame rate video signal;
analyze a video synchronization signal of the high frame rate video signal;
delete a video synchronization signal of a frame set to non-emission based on the analysis result of the video synchronization signal;
extend an emission time of a frame directly before the frame set to non-emission into less than a full length of a field of the frame set to non-emission; and
control a display panel to display a video based on the setting, the analyzing, the deleting and the extending.
2. The image display device of claim 1 , wherein
the circuitry is configured to extend the emission time of the frame directly before the frame set to non-emission into less than 50% the length of the field of the frame set to non-emission.
3. The image display device of claim 2 , wherein
the circuitry is configured to extend the emission time of the frame directly before the frame set to non-emission into 40% of the length of the field of the frame set to non-emission.
4. The image display device of claim 1 , wherein
the input video signal is a 60 Hz video signal and the circuitry is configured to generate a 120 Hz video signal as the high frame rate video signal by increasing the frame rate of the 60 Hz video signal.
5. The image display device of claim 1 , further comprising:
the display panel, wherein the display panel is an organic electroluminescence (EL) display panel.
6. The image display device of claim 1 , wherein
the circuitry is configured to extend an emission time of a frame directly after a frame set to non-emission into a portion of a field of a preceding frame set to non-emission.
7. An image display method, comprising:
generating a high frame rate video signal by increasing a frame rate of an input video signal;
