PROJECTOR AND METHOD OF CONTROLLING PROJECTOR

摘要

A projector (100) including a projection section (101) adapted to project an image on a screen (SC), a CPU (120) adapted to make the projection section project a correction pattern (177a) so as to be superimposed on the image presently projected if a start condition of the distortion correction process is satisfied, and a correction control section (122) and a keystone distortion correction section (132) adapted to perform the distortion correction process based on a state of the correction pattern, and the CPU makes the projection section project the correction pattern in a state in which a result of the distortion correction process fails to be reflected during a period from when the start condition of the distortion correction process is satisfied to when a condition for completing the distortion correction process is satisfied, and a period in which the keystone distortion correction section performs the distortion correction process a plurality of times.

1. A projector comprising:
a projection unit adapted to project an image on a projection surface; a controller adapted to make the projection unit project a correcting image so as to be superimposed on the image presently projected if a start condition of a distortion correction process adapted to correct a distortion of the image projected by the projection unit is satisfied; and a correction unit adapted to perform the distortion correction process based on a state of the correcting image projected by the projection unit, wherein the controller makes the projection unit project the correcting image in a state in which a result of the distortion correction process fails to be reflected during a period from when the start condition of the distortion correction process is satisfied to when a condition for completing the distortion correction process is satisfied, and a period in which the correction unit performs the distortion correction process a plurality of times.
