ABSTRACT:
A projection system is provided which includes a projection lens and a spatial optical modulation device (SOM) for projecting an image in response to an inputted picture signal. A control unit enables the selection, via an image adjustment menu, of at least one of a rotational deformation adjustment in which a projected image is rotated and a keystone deformation adjustment in which the projected image is deformed into a rectangle, and the control unit applies a rotational deformation adjustment and a keystone deformation adjustment to the projected image based on an item selected in the image adjustment menu in response to a deformation indication inputted from a keys/indicators unit, so as to deform the projected image.
