摘要:
A laser projector includes a drive signal generation unit for processing an input image signal to generate a laser drive signal and a scanner drive signal, a pixel position detection unit for detecting positions of pixels corresponding to a one-frame image from the generated scanner drive signal, a compensation value decision unit for deciding a brightness compensation value corresponding to the detected pixels, a compensation unit for compensating a laser drive signal corresponding to the detected pixels according to the decided brightness compensation value, a laser light source for generating laser light according to the compensated laser drive signal, and a scanner for scanning the laser light according to the scanner drive signal.
