ABSTRACT:
A projector apparatus comprises a light source lamp which is inside a reflector, a projection system forming a light figure using a light from the light source lamp, projecting the formed light figure by an optical lens unit having an automatic focus function and providing the image on a projection target position, a temperature sensor detecting the temperature of the light source lamp, a temperature sensor detecting the temperature of the optical lens unit, and a control unit moving the position of a focus lens of the optical lens unit in accordance with each detection result of the temperature sensors, thereby revising an image location set by the automatic focus function.
