Projector and projection correction method thereof
First Claim
1. A projection correction method, adapted to a projector, the projection correction method comprising:
- sensing a temperature of a body of the projector to obtain a first temperature value, wherein a focusing gear of the projector is located at a first gear position;
determining whether the temperature of the body of the projector is changed, and when the temperature of the body of the projector is changed from the first temperature value to a second temperature value, rotating the focusing gear by a predetermined distance to rotate the focusing gear to a second gear position; and
determining whether a storage device stores a target gear position corresponding to the second temperature value, so as to rotate the focusing gear to the target gear position.

Abstract
A projection correction method adapted to a projector. The projection correction method includes: sensing a temperature of a body of the projector, so as to obtain a first temperature value, where a focusing gear of the projector is located at a first gear position; determining whether the temperature of the body of the projector is changed, and when the temperature of the body of the projector is changed from the first temperature value to a second temperature value, the focusing gear is rotated by a predetermined distance to rotate the focusing gear to a second gear position; and determining whether a storage device stores a target gear position corresponding to the second temperature value, so as to rotate the focusing gear to the target gear position. Moreover, a projector using the aforementioned projection correction method is also provided.

9. A projector, comprising:
-
a focusing gear, located at a first gear position; a temperature sensor, configured to sense a temperature of a body of the projector to obtain a first temperature value; a processing device, coupled to the temperature sensor and controlling the focusing gear, wherein the processing device is configured to determine whether the temperature of the body of the projector is changed by the temperature sensor, and rotate the focusing gear by a predetermined distance when the temperature of the body of the projector is increased from the first temperature value to a second temperature value, so as to rotate the focusing gear to a second gear position; and a storage device, coupled to the processing device, wherein the processing device determines whether the storage device stores a target gear position corresponding to the second temperature value to rotate the focusing gear to the target gear position. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
