Abstract
Disclosed is a method of controlling a display device displaying an image using a lens, the method including storing a lens distortion parameter for chromatic aberration correction, receiving image data, primarily calculating a distance between a center point and a current pixel, secondarily calculating a distortion correction weight in consideration of the distance, and outputting image data of the current pixel through calculation according to the calculated distortion correction weight without using the stored lens distortion parameter intactly.
Claims20
A method of controlling a display device displaying an image using a lens, the method comprising:
- storing a lens distortion parameter for chromatic aberration correction;
- receiving image data;
- primarily calculating a distance between a center point and a current pixel;
- secondarily calculating a distortion correction weight in consideration of the distance;
- and
- outputting image data of the current pixel through calculation according to the calculated distortion correction weight without using the stored lens distortion parameter intactly.
A display device displaying an image using a lens, the display device comprising:
- a memory storing a lens distortion parameter for chromatic aberration correction;
- and
- a controller configured to receive image data, primarily calculate a distance between a center point and a current pixel, secondarily calculate a distortion correction weight in consideration of the distance, and output image data of the current pixel through calculation according to the calculated distortion correction weight without using the stored lens distortion parameter intactly.
A Head Mounted Display (HMD), comprising:
- a strap fixable to a user's body;
- a memory storing a lens distortion parameter for chromatic aberration correction;
- and
- a controller configured to receive image data, primarily calculate a distance between a center point and a current pixel, secondarily calculate a distortion correction weight in consideration of the distance, and output image data of the current pixel according to the calculated distortion correction weight.
