Abstract
In the usage of table projection of a projection type display, depending upon a sitting position of a participant of a conference, the participant views an image projected upon a table as an inversion image turned upside down, resulting in poor visual recognition. In order to improve visual recognition, images are rotated, synthesized and displayed in accordance with the viewing direction of each participant. More specifically, the projection type display is provided with a two-image synthesizing unit for synthesizing two images obtained by processing an input image by two image rotation units for rotating the input image by a first angle and a second angle different from the first angle, into one image on a screen. The projection type display is also provided with an image rotation unit and an image inversion unit for two-image display on a screen.
