Abstract:
1. A laser image display device, comprising: a first laser light source that emits a first laser beam having a first wavelength; a second laser light source that emits a second laser beam having a second wavelength; and a color output conversion controller that controls powers of the first laser beam and the second laser beam based on an input signal, the first and second laser beams displaying a pixel of an image, wherein: said color output conversion controller controls the power of the first laser beam which displays the pixel between a first minimum power and a first maximum power; said color output conversion controller controls the power of the second laser beam which displays the pixel between a second minimum power and a second maximum power; and when the input signal indicates an end point of a color reproducible region of said laser image display device with respect to display of the pixel, the end point of the color reproducible region being able to be displayed by substantially displaying the first laser beam with the first maximum power and by substantially displaying the second laser beam with the second minimum power, said color output conversion controller controls the powers of the first and second laser beams such that the pixel is displayed by the first laser beam having a first power less than or equal to the first maximum power and the second laser beam having a second power greater than the second minimum power so that the pixel displays a color that is included in the color reproducible region except for the end point.
