Abstract:
1. A projector apparatus comprising: a group of light sources source configured to emit light beams of a plurality of color components; a projection unit configured to project an image using the light beams from the group of light sources; a driving unit configured to drive the group of light sources so that the light beams are emitted as light pulses having respective pulse widths for a period in which the projection unit projects the image; a controller configured to control the pulse widths of the light pulses emitted from the group of light sources; and measuring unit configured to measure illumination values of the group of light sources for each of the plurality of color components, wherein the controller is configured to determine whether the illumination value for each of the plurality of color components is smaller than a predetermined value; and wherein the controller is configured to narrow the pulse width of a light pulse of a light source in the group of light sources that is determined to have an illumination value that is not smaller than the predetermined value if it is determined that an illumination value of another light source in the group of light sources is smaller than the predetermined value.
