摘要： To control a laser used as a light source according to an input image, while satisfying a safety standard, a projector includes lasers provided for each of a plurality of colors, a dichroic mirror that synthesizes laser beams emitted by the lasers, an LCOS panel that modulates synthesized light by the dichroic mirror, and a projection lens that projects the light modulated by the LCOS panel. A processor determines rate of power of the laser beams according to the image signal, determines, according to the rate of the power, an upper limit value of the power of the projected laser beam in each color to the extent that the upper limit value satisfies a safety standard, and adjusts the laser beam in each color emitted by the corresponding laser so as to prevent the projected light beam in each color from exceeding the upper limit value.
