Image displaying apparatus and display controlling device

A display controlling device that is operable to control driving of laser light sources and a spatial modulation element that are included in an image displaying apparatus including the laser light sources corresponding to a plurality of colors, while at least one of the laser light sources corresponding to one of the colors includes a plurality of wavelength conversion laser light sources corresponding to a mutually same color and has a plurality of outputs, the image displaying apparatus being operable to display a color image by causing the spatial modulation element to perform a spatial modulation process on laser beams output from the laser light sources by using a field sequential method, the display controlling device comprising:

• a drive controlling unit that, when the spatial modulation element performs the spatial modulation process on the laser beams output from the at least one of the laser light sources having the plurality of outputs, during a time period assigned to the one of the colors corresponding to the laser light source having the plurality of outputs, controls timing with which a pulse driving is performed by each of the wavelength conversion laser light sources so that the wavelength conversion laser light sources sequentially output pulses in such a manner that the laser beams output from the wavelength conversion laser light sources have a substantially same peak power as one another and so that substantially constant laser outputs are continuously obtained from the wavelength conversion laser light sources and causes the wavelength conversion laser light sources to output the laser beams in such a manner that there is a predetermined delay period between an ending point of the pulse of the laser beam output from one of the wavelength conversion laser light sources that is driven first and a starting point of the pulse of the laser beam output from another one of the wavelength conversion laser light sources that is driven second and also that a trailing section of the first-driven laser beam partially overlaps a rising section of the second-driven laser beam, while the first-driven wavelength conversion laser light source and the second-driven wavelength conversion laser light source are light sources of the same color.
