Abstract
A projection device is provided, which is capable of suppressing or preventing problems that result from a light emission delay of a light source. The projection device includes a plurality of light sources respectively emitting a laser light; a scanning part enabling the laser light to scan; and a controller controlling an output of the laser light. In a scanning range including a first scanning range and a second scanning range, the controller controls such that the output has a first light amount in the first scanning range and has a second light amount which is greater than the first light amount in the second scanning range.
