ABSTRACT:
A method is used with a document camera and an image display device for adjusting the image display range. The document camera includes an image synthesis controller and a graphics buffer. In the method, a first image frame and a second image frame are received by the image synthesis controller. In response to the image parallel display information, the graphics buffer is divided into a first region and a second region, and the image synthesis controller fills partial data of the first image frame and second image frame into the first region and the second region, respectively. In response to a change of the image parallel display information made by the user, the graphics buffer is divided into a third region and a fourth region, and the image synthesis controller fills partial data of the first image frame and second image frame into the third region and the fourth region, respectively. The data filled in the graphics buffer is then outputted to the image display device as a synthesized frame to be displayed.
