<P>PROBLEM TO BE SOLVED: To provide a projector device in which, even if a plurality of light sources and an element or the like of a phosphor are deteriorated with time, they are compensated and the color reproducibility and brightness of projection images are made compatible for a long time. <P>SOLUTION: The projector device includes semiconductor laser 20 which emits blue (B) light, a color wheel (CW) 24, and a motor 25 which generates a blue (B) light of transmission light in time division from the blue light and a green (G) light of reflection fluorescent light, an LED 21 which emits red (R) light, a light sensor LS which detects the light intensity of the plurality of colors from the light source 17, a projection light processing part 31 and a CPU 32 which control the drive timing of the semiconductor laser 20 and LED 21 so that the B light, G light, and R light may be generated cyclically and adjust emission states of the semiconductor laser 20 and the LED 21 based on the detection result by the light sensor LS, input parts (11, 12) which input image signals, and projection systems (13-16, 18, 19) which form the light image of a color corresponding to the image signal input by the input parts (11, 12) and project it by using the RGB light. <P>COPYRIGHT: (C)2011,JPO&INPIT |
