<p>After power is turned on, a control section (2) causes a distance detecting section (8) to detect a distance up to a screen, and controls focus positions of a projector lens (62) and an imaging lens (71) in synchronization with each other based on the detected distance (projection distance and subject distance) and an initialized zoom ratio. Moreover, when a change operation in angle of view is executed by a user in a user control apparatus (5), the control section (2) changes a zoom ratio of the projector lens (62) according to the user's operation and changes a zoom ratio of the imaging lens (71) to correspond to the zoom ratio of the projector lens (62). The control section (2) controls the zoom ratio and the focus position of the imaging lens (71) in synchronization with setting of the zoom ratio and the focus position of the projector lens (62).</p> |
