Abstract
The laser projection display device () includes a laser beam source (), a laser driver () driving the laser beam source, and an image processing unit () supplying a display image signal to the laser driver. The image processing unit applies a preliminary emission signal () to perform preliminary emission to an image signal () in a predetermined period (tto t) immediately before a black pixel signal is switched to a signal except for the black pixel signal when the image signal has a black pixel duration. In particular, the preliminary emission process is performed when the laser beam source is operated in a dark image region while being reduced in maximum light intensity, and, as the preliminary emission signal, a signal (L) corresponding to a light intensity which is 1/10 or less a maximum light intensity (La) in the dark image region.
