Abstract
A projector that can be easily set up and adjusted is disclosed. In accordance with a projection condition inputted into a microcomputer via a remote-controller, the microcomputer selects an optimum projection lens by referring to correlation data showing a relation among a projection lens, a projection display size, and an optimum projection distance. The microcomputer has a screen to indicate an optimum projection lens and projection distance that satisfy the inputted projection condition. The microcomputer calculates the amounts of zoom and focus adjustments to be made to the projection lens with reference to the correlation data so as to attain the projection display size and the microcomputer automatically drives the projection lens via a zoom driving unit and a focus driving unit.
