Abstract
A projector includes a plurality of light-sources that outputs a laser light, a detector that detects a light amount of the laser light, and a controller that controls an output of the light-sources based on a characteristic indicating a relationship between a forward current value and a light output when a current value of the light-sources is smaller than a predetermined current value. When the current value of the light-sources is greater than or equal to the predetermined current value, the controller controls the output of the light-sources based on the detected light amount. The predetermined current value is a current value that can be laser-oscillated.
