APPARATUS AND METHOD FOR CORRECTING IMAGE FOR IMAGE PROJECTION DEVICE WITH COGNITIVE FUNCTION ON USER AND ENVIRONMENT |
| 摘要 |
Disclosed is a method of correcting an input image when projecting the input image using an image projection device. The method includes obtaining information on a projection surface on which the input image is to be projected and information on a user's position through at least one image sensor, performing geometric correction on the input image based on the information on the projection surface and the information on the user's position, performing color correction on the input image based on the information on the projection surface, and performing brightness correction on the input image based on the information on the projection surface. |
