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 9):
A device for projection parameter adjustment comprising:\n a display control circuit, configured to control a projector to display a plurality of predetermined patterns in accordance with a plurality of predetermined display conditions corresponding to the plurality of predetermined patterns, each of predetermined patterns corresponding to a projection parameter; a luminance acquisition circuit, configured to measure luminance of a plurality of predetermined positions in a theoretical display area of the projector in accordance with the predetermined measurement condition; a matching judgment circuit, configured to judge whether the predetermined patterns match with the theoretical display region in accordance with the luminance of the plurality of predetermined positions; a control circuit, configured to generate an adjustment signal for adjusting the projector under the condition a judgment result indicating a mismatch is received from the matching judgment circuit and generate an enabled signal for controlling operation of the luminance acquisition circuit after the adjustment signal is generated; and a drive circuit, configured to adjust operation of the projector in accordance with the adjustment signal output from the control circuit.
