PROJECTION DEVICE HAVING A MODE SELECTION UNIT

摘要

The invention relates to a projection device for projecting an image comprising a light source (1), electro-optical light modulation means (22) and image projection means (12) for projecting the image. In order to provide a projection device that can be used and is optimized for different modes, such as for video applications and business applications, the projection device according to the present invention further comprises a switchable module (3) comprising at least a first submodule (31), and a mode selection unit (20) for controlling said module (3) such that said first submodule (31) is either active or not active in the light path from said light source (1) to said image projection means (12), said first submodule (31) being adapted to improve the center brightness and white point of the light.
