Abstract
A three-dimensional (3D) image display device may display a perceived 3D image. A location tracking unit may determine a viewing distance from a screen to a viewer. An image processing unit may calculate a 3D image pixel period based on the determined viewing distance, may determine a color of at least one of pixels and sub-pixels displaying the 3D image based on the calculated 3D image pixel period, and may control the 3D image to be displayed based on the determined color.
Claims21
A method for displaying a perceived three-dimensional (3D) image, the method comprising:
- determining a viewing distance from a screen to a viewer;
- calculating an image pixel period based on the determined viewing distance without any change of a pattern period of a stereoscopic image filter;
- determining a color of at least one of pixels and sub-pixels for displaying a perceived 3D image based on the calculated image pixel period;
- and
- displaying the image based on the determined color,
- wherein the image pixel period is a period of pixel data of a part of a perceived 3D image that can be seen by one eye of the viewer at the determined viewing distance,
- the image pixel period is calculated based on the determined viewing distance, a distance between the display panel and the stereoscopic image filter, and the pattern period of the stereoscopic image filter,
- when the determined viewing distance is greater than a predetermined viewing distance, the image pixel period of the image is calculated to be less than a predetermined image pixel period corresponding to the predetermined viewing distance, and
- when the determined viewing distance is less than a predetermined viewing distance, the image pixel period of the image is calculated to be greater than the predetermined image pixel period corresponding to the predetermined viewing distance.
An image display device to display a perceived three-dimensional (3D) image, the image display device comprising:
- a location tracking unit to determine a viewing distance from a screen to a viewer;
- and
- an image processing unit to calculate an image pixel period based on the determined viewing distance without any change of a pattern period of a stereoscopic image filter, to determine a color of at least one of pixels and sub-pixels for displaying a perceived 3D image based on the calculated image pixel period, and to control the image to be displayed based on the determined color, wherein
- the image pixel period is a period of pixel data of a part of a perceived 3D image that can be seen by one eye of the viewer at the determined viewing distance,
- the image pixel period is calculated based on the determined viewing distance, a distance between the display panel and the stereoscopic image filter, and the pattern period of the stereoscopic image filter,
- when the determined viewing distance is greater than a predetermined viewing distance, the image processing unit is configured to calculate the image pixel period of the image to be less than a predetermined image pixel period corresponding to the predetermined viewing distance, and
- when the determined viewing distance is less than a predetermined viewing distance, the image processing unit is configured to calculate the image pixel period of the image to be greater than the predetermined image pixel period corresponding to the predetermined viewing distance.
