Abstract
A projection method is provided. The projection method comprises the steps of identifying the resolution of an original image, comparing the resolution of the original image with a preset resolution to generate a comparison result, determining whether to deflect a projection lens in a projection process according to the comparison result, and projecting at least one image in the projection process according to the comparison result.
Claims11
A projection method, comprising:
- identifying the resolution of an original image;
- comparing the resolution of the original image with a preset resolution to generate a comparison result;
- determining whether to deflect a projection lens in a projection process according to the comparison result;
- and
- projecting at least one image in the projection process according to the comparison result.
2 more elements
A projector, comprising:
- a projection lens;
- a lens deflector, electrically connected with the projection lens and configured to deflect the projection lens;
- a resolution identification unit, configured to identify the resolution of an original image;
- a comparison unit, coupled to the resolution identification unit and configured to compare the resolution of the original image with a preset resolution to generate a comparison result;
- and
- an actuator, coupled to the lens deflector and configured to actuate the lens deflector when the comparison unit determines that the resolution of the original image is higher than the preset resolution, and the actuator does not actuate the lens deflector when the comparison unit determines that the resolution of the original image is lower than or equal to the preset resolution.
