Claim Text:
1. A projection apparatus for displaying an image based on an input image signal by emitting light from a light source, the projection apparatus comprising: a detection unit configured to detect gradation information from the input image signal; a determination unit configured to determine a number of light emissions of the light source for displaying an image corresponding to one image frame based on the input image signal based on the gradation information detected from the input image signal by the detection unit such that a number of light emissions of the light source for displaying the image corresponding to one image frame based on the input image signal is larger in a case where the gradation information detected from the input image signal by the detection unit corresponds to higher brightness than a predetermined brightness in comparison with a case where the gradation information detected from the input image signal by the detection unit corresponds to lower brightness than the predetermined brightness; and a control unit configured to control the light source according to the determination of the number of light emissions of the light source based on the gradation information of the input image signal by the determination unit.
