| Abstract: | More than one projector is frequently used for large scale screen application.The blending effect of images from separate projectors has always been the crucial criteria of the application.Based on the analysis of traditional Alpha blending method,in this article it analyzes the correction method for nonlinear brightness changes in projecting phase of the projector and gropes the application of Gamma Correction in projectors' image splicing. |
