Abstract
A projector system may include a camera, a controller unit and a projecting unit. The camera may pick up a first image of a projection surface by visible light and a second image of the projection surface by a decreased visible light. The controller unit may perform a keystone distortion correction processing on a basis of the first image and perform an interactive processing on a basis of the second image. The projecting unit may project an image based on the performed keystone distortion correction.
Claims7
A projector system comprising:
- a camera that picks up a first image of a projection surface by a visible light, and picks up a second image of the projection surface by a decreased visible light;
- a controller unit that performs a keystone distortion correction processing on a basis of the first image and performs an interactive processing on a basis of the second image;
- and
- a projecting unit that projects an image based on the keystone distortion correction performed.
An image projecting method for a projector system including a camera, comprising:
- picking up a first image of a projection surface by visible light by the camera;
- performing a keystone distortion correction processing on a basis of the first image;
- picking up a second image of the projection surface by decreased visible light by the camera;
- performing an interactive processing on a basis of the second image;
- and
- projecting an image based on the keystone distortion correction performed.
A projector comprising:
- a controller unit that performs a keystone distortion correction processing and an interactive processing;
- a camera that picks up for the keystone distortion correction processing via a visible light, and that picks up for the interactive processing via a decreased visible light;
- and
- a projecting unit that projects an image based on the keystone distortion correction performed,
- wherein the camera combines for the keystone distortion processing and the interactive processing.
