Abstract
The present invention relates to an electronic device and method for controlling a display by eye tracking. The method for controlling a display by eye tracking according to the present invention may comprise the steps of: tracking of line of sight of eyes; displaying, on a screen, a user interface for controlling the screen using the tracked line of sight; and executing a function selected in response to a selection of any menu item of the user interface by the tracked line of sight.
Claims20
A method of capturing an image by an electronic device, the method comprising:
- measuring ambient brightness;
- emitting a light source by controlling a brightness strength of the light source and an exposure time of the light source to capture an image based on the measured ambient brightness;
- generating a plurality of frames by capturing the image based on the emitted light source;
- and
- selecting at least one frame from among the generated plurality of frames, wherein the at least one frame is selected based on signal to noise ratios (SNRs) of the generated plurality of frames and brightnesses of the generated plurality of frames.
An electronic device for capturing an image, the electronic device comprising:
- a light emitting unit comprising at least one light emitting element for emitting a light source;
- a camera unit configured to capture an image based on the emitted light source;
- a detection unit configured to measure ambient brightness to capture the image;
- and
- a controller configured to:
- emit the light source by controlling a brightness strength of the light source and exposure time of the light source to capture the image based on the measured ambient brightness,
- generate a plurality of frames by capturing the image based on the emitted light source, and
- select at least one frame from among the generated plurality of frames, wherein the at least least one frame is selected based on signal to noise ratios (SNRs) of the generated plurality of frames and brightnesses of the generated plurality of frames.
