Japanese Patent JP6229784
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress change in brightness even when lighting time of a solid light source changes.SOLUTION: A signal processing part 110 increases duty ratio of a PWM signal PY2 for driving an excitation laser diode 62 as brightness of an image is increased. The signal processing part 110 denotes a current value of the PWM signal PY2 by b in a range where the brightness of the image is from 0% to less than f%, and a current value of the PWM signal PY2 by a (a>b) in a range where the brightness of the image is equal to e% (f%
