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 5):
The method for projection parameter adjustment according to  claim 4 , wherein the projection parameter comprises a position of the lens of the projector, the predetermined patterns include a third predetermined pattern which has a second predetermined luminance and a shape similar to the theoretical display area, and the third predetermined pattern covers all the plurality of predetermined positions;\n Step S 1  comprises: controlling the third predetermined pattern to be gradually reduced until there is a predetermined position where a third predetermined luminance less than the second predetermined luminance is reached in the plurality of predetermined positions; Step S 2  comprises: measuring the luminance of the plurality of predetermined positions and recording a time at which each of predetermined positions reaches the third predetermined luminance; Step S 3  comprises: determining that the third predetermined pattern does not match with the theoretical display area under the condition the plurality of predetermined positions reach the third predetermined luminance at different time; and determining that the third predetermined pattern matches with the theoretical display area under the condition the plurality of predetermined positions reach the third predetermined luminance at the same time; and Step S 4  comprises: translating the lens of the projector in a direction towards the predetermined position that first reaches the third predetermined luminance.
