Abstract:
There is provided a method and device for projection parameter adjustment and a projection apparatus. The method comprises adjusting a projector in accordance with predetermined patterns sequentially, wherein the predetermined patterns correspond to respective projection parameters. For each predetermined pattern, step of adjusting the projector according to the predetermined pattern includes: controlling the projector to display the predetermined pattern in accordance with a predetermined display condition corresponding to the predetermined pattern; measuring luminance of predetermined positions in a theoretical display area of the projector in accordance with the predetermined measurement condition; judging whether the predetermined pattern matches with the theoretical display region in accordance with the luminance; and under the condition the predetermined pattern does not match with the theoretical display area, adjusting the projector and repeating above steps until the predetermined pattern matches with the theoretical display area.

Claim (Index 4):
The method for projection parameter adjustment according to  claim 3 , wherein the projection parameter comprises an angle at which the lens of the projector rotates about the axis of the lens, the predetermined patterns include a second predetermined pattern which is a part of the first predetermined pattern, and a connecting line of at least two predetermined positions in the plurality of predetermined positions is parallel to the width direction of the theoretical display area, and wherein\n Step S 1  comprises: controlling the second predetermined pattern to move from one side to the other side of an area corresponding to the first predetermined pattern; Step S 2  comprises: measuring the luminance of a plurality of predetermined positions and recording a time at which each of predetermined positions reaches the first predetermined luminance; Step S 3  comprises: determining that the second predetermined pattern does not match with the theoretical display area under the condition the at least two predetermined positions having the connecting line parallel to the width direction of the theoretical display area reach the first predetermined luminance at different time; and determining that the second predetermined pattern matches with the theoretical display area under the condition the at least two predetermined positions having the connecting line parallel to the width direction of the theoretical display area reach the first predetermined luminance at the same time; and Step S 4  comprises: rotating the lens of the projector about the axis of the lens of the projector.
