Abstract:
A projection apparatus for projecting an image of a display unit by emitting light from a light source includes a detection unit configured to detect flicker information indicating how easily flicker occurs based on input image information, and a control unit configured to control the number of light emissions of the light source in a time period during which an image in one frame is displayed by the display unit based on the flicker information detected by the detection unit.
