Projection apparatus for projecting video signal to projection surface, has projection unit for generating broadcasting light signal based on video input signal

摘要

The projection apparatus (100) has a projection unit (PE) for generating a broadcasting light signal based on a video input signal (IN). A sensor unit (SE) is provided for detecting the location information regarding a person (200) between the projection apparatus and a projection surface (300). A correction unit (K) is provided for calculating a correction signal based on the location information collected by the sensor unit. An independent claim is also included for a method for projecting a video signal to a projection surface.
