PROJECTION APPARATUS, PROJECTION METHOD, AND PROJECTION PROGRAM MEDIUM |
| 摘要 |
A CPU of a projector determines whether or not a correction mode in which the aspect ratio of an input image is changed to correct distortion is set and, if the correction mode is set, determines distortion correction process parameters for changing the aspect ratio of the image to be projected onto a screen to project the image in the form of a rectangular image, and the image converter performs geometric correction on the input image on the basis of the distortion correction process parameters to project the image subjected to distortion correction. |
