Abstract
Techniques for displaying a multimedia in at least two resolutions are discussed. Depending on implementation, a resolution can be a spatial resolution, an intensity level resolution, or both. A display device is designed to ensure better resolution in an area (region of focus or ROF) being focused by eyes of a viewer while relatively poor resolution in the area surrounding the ROF. The ROF moves accordingly with the motion of the pupil. As a result, the perceived resolution by the user remains high while the memory requirement for displaying such media is significantly reduced.
Claims20
A display system comprising:
- a display screen;
- a pupil detector, disposed near the display screen, provided to track motion of an eye looking at the display screen;
- an area calculator, coupled to the pupil detector, determining a region of focus (ROF) on the display screen for the eye in accordance with an output from the pupil detector, wherein the ROF is where the eye is looking at on the display screen;
- and
- a sampling circuit generating a sampling signal in at least two different rates, first and second sampling rates, wherein the first sampling rate is applied when data from a media to be displayed in the ROF, and the second sampling rate is applied when data from the media to be displayed in an area other than the ROF.

A display method comprising:
- tracking by a pupil detector motion of an eye looking at a display screen;
- determining a region of focus (ROF) on the display screen for the eye in accordance with an output from the pupil detector, wherein the ROF is where the eye is looking at on the display screen;
- and
- generating a sampling signal in at least two different rates, first and second sampling rates, wherein the first sampling rate is applied when data from a media to be displayed in the ROF, and the second sampling rate is applied when data from the media to be displayed in an area other than the ROF.
