Abstract
A keystone correction apparatus and method of curved display are provided. The apparatus includes a curved screen that displays an image and a projector that has an infrared lighting device to irradiate infrared light to the curved screen. An infrared imaging device is configured to capture infrared light reflected from the curved screen. A controller is configured to determine whether the curved screen is distorted using an infrared image captured by the infrared imaging device and perform a keystone correction.
Claims12
A keystone correction apparatus of a curved display, comprising:
- a curved screen configured to display an image;
- a projector that includes an infrared lighting device configured to irradiate infrared light to the curved screen;
- an infrared imaging device configured to capture infrared light reflected from the curved screen;
- and
- a controller configured to determine whether the curved screen is distorted using an infrared image captured by the infrared imaging device and perform a keystone correction.
A keystone correction method of a curved display, comprising:
- receiving, by a controller, an infrared image captured by an infrared imaging device, wherein the infrared image is captured from infrared light reflected from a curved screen and projected onto the curved screen by a projector;
- determining, by the controller, whether the curved screen is distorted using the captured infrared image;
- and
- performing, by the controller, a keystone correction when the curved screen is distorted.
A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:
- program instructions that receive an infrared image captured by an infrared imaging device, wherein the infrared image is captured from infrared light reflected from a curved screen and projected onto the curved screen by a projector;
- program instructions that determine whether the curved screen is distorted using the captured infrared image;
- and
- program instructions that perform a keystone correction when the curved screen is distorted.
