Laser projection display system

A laser projection display system configured to execute, by swinging a scan mirror, scanning with laser light of multiple colors in accordance with image signals, thereby displaying an image in accordance with the image signals, the laser projection display system comprising:

• a laser light source configured to generate the laser light of the multiple colors;
• a laser light source driving unit configured to drive the laser light source;
• a scan mirror driving unit comprising:
• first scanning means configured to execute scanning in a first direction in response to synchronization signals according to the image signals, with laser light generated by the laser light source through the scan mirror;
• and second scanning means configured to execute scanning in a second direction substantially perpendicular to the first direction at a lower speed than the first scanning means;
• and
• a timing adjustment unit configured to vary proportions of a display period during which the image signals are displayed in one period for the first scanning means, and of a light emission period for intensity detection to detect intensity of the laser light, in accordance with a deflection angle in scanning by the second scanning means,
• wherein the scan mirror driving unit varies an angular range of a deflection angle in scanning by the first scanning means, in accordance with the proportion of the display period in one period for the first scanning means.
