Abstract

According to the present invention there is provided a method for projecting an image on to a display surface, comprising the steps of, providing two or more projection systems; arranging the two or more projection systems such that they each project an image on a display surface; off-setting an oscillating reflective surface within at least one of the two or more projection systems such that the image projected by each of the two or more projection systems are in co-operation on the display surface.

Claims

exact text as granted — not AI-modified
1 . A method for projecting an image onto a display surface, comprising the steps of:
 a. providing two or more projection systems;   b. arranging the two or more projection systems such that they each project an image on a display surface;   c. off-setting an oscillating reflective surface within at least one of the two or more projection systems such that the image projected by each of the two or more projection systems are in co-operation on the display surface.   
     
     
         2 . The method according to  claim 1 , wherein the two or more projection systems are independent of one another. 
     
     
         3 . The method according to  claim 1 , wherein, the two or more projection systems are each configured such that the image projected by each projection system co-operate by overlapping. 
     
     
         4 . The method according to  claim 1 , wherein, the two or more projection systems are each configured such that the image projected by each projection system co-operate by aligning. 
     
     
         5 . The method according to  claim 1 , wherein, the two or more projection systems are each configured such that the image projected by each projection system co-operate by meshing. 
     
     
         6 . The method according to  claim 1 , further comprising the step of, detecting the position on the display surface of the images projected by the two or more projection systems. 
     
     
         7 . The method according to  claim 1 , further comprising the step of, modifying the speed at which a reflective surface of a projection system oscillates. 
     
     
         8 . The method according to  claim 1 , further comprising the step of, modifying the modulation of a light source in a projection system. 
     
     
         9 . The method according to  claim 1 , further comprising the step of, adjusting the brightness of the light projected by one or more of the projection systems. 
     
     
         10 . A method according to  claim 1 , comprising the step of configuring each of the two or more projection systems such that the image projected by each projection systems comprises a portion of a resolution of a complete image to be displayed on the display surface. 
     
     
         11 . A method according to  claim 1 , further comprising the step of detecting the size of the images projected by some or all of the two or more projection systems. 
     
     
         12 . A method according to  claim 1 , further comprising the step of detecting the brightness of the images projected by some or all of the two or more projection systems. 
     
     
         13 . A method according to  claim 1 , further comprising the step of configuring each of the two or more projection systems such that they project a test image which is used to determine how the two or more projection systems should be configuring such that images projected by each of the projection system are in co-operation on the display surface. 
     
     
         14 . A method according to  claim 1 , further comprising the step of detecting colors of the images projected by some or all of the two or more projection systems. 
     
     
         15 . An arrangement comprising two or more mobile devices each of which comprises a projection system, wherein the projection systems are configured such that they can be used to carry out a method according to  claim 1 .
