Abstract
A drawing apparatus includes a laser light source unit configured to output laser light; a scanning mirror unit configured to reflect and scan the laser light; a drawing control unit configured to control an output value of the laser light of the laser light source unit based on display image data so that a display image is drawn by the laser light in a range scanned by the scanning mirror unit; and an output adjustment control unit configured to control the laser light source unit so that characteristic detection laser light for adjusting the output value is output outside a range in which the display image is drawn inside the range scanned by the scanning mirror unit. The output adjustment control unit controls the characteristic detection laser light to be output based on a display color at an end part of the display image.
