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 3):
The method for projection parameter adjustment according to  claim 1 , wherein the projection parameter comprises a position where the projector is placed, and the predetermined patterns include a first predetermined pattern in a rectangular shape having a first predetermined luminance, and wherein\n Step S 1  comprises: controlling the projector to display the first predetermined pattern under the condition the projector being in a state of the maximum focal length; Step S 2  comprises: measuring the luminance of each predetermined position, respectively; Step S 3  comprises: determining that the first predetermined pattern does not match with the theoretical display area under the condition there is a position in the plurality of predetermined positions where the luminance is less than the first predetermined luminance; and determining that the first predetermined pattern matches with the theoretical display area under the condition the luminance of the plurality of predetermined positions is greater than or equal to the first predetermined luminance.
