<p>When the scanning position of a scanning unit is at the edge section of an effective display area in which an image is formed by scanning laser light outputted from a light source unit with the scanning unit, a drive signal for the edge section predetermined for the edge section is outputted by a drive control unit to control the light source unit to output laser light having a predetermined intensity, and the intensity of the laser light outputted from the light source unit in response to the drive signal for the edge section is detected by a light intensity detection unit.</p> |
