PROJECTOR WITH THREE-DIMENSIONAL DISPLAY

摘要

A projector includes a lamp that emits projection light to project 3D picture, in which a right eye image and a left eye image are represented in a time division manner, to an object, a synchronization signal transmission section which transmits shutter synchronization signal to glasses having a right eye shutter and a left eye shutter to control the opened state or the closed state of the right eye shutter and the left eye shutter, based on the signal indicating a displaying period of the right eye image and the left eye image of 3D picture, and a lamp drive section that supplies AC current having peak overlapping with a period when the right eye shutter of the glasses is in the opened state and peak overlapping with a period when the left eye shutter of the glasses is in the opened state to the lamp, based on the signal.

1. A projector comprising:
a lamp that emits projection light to project 3D picture, in which a right eye image and a left eye image are presented in a time division manner, to an object; a synchronization signal transmission section which transmits shutter synchronization signal to a pair of glasses having a right eye shutter and a left eye shutter which are in an opened state or a closed state independently, to control the opened state or the closed state of the right eye shutter and the left eye shutter, based on a signal indicating a displaying period of the right eye image and the left eye image of the 3D picture; and a lamp drive section that supplies AC current having a peak overlapping with a period when the right eye shutter is in the opened state and a peak overlapping with a period when the left eye shutter is in the opened state to the lamp, based on the signal indicating the displaying period of the right eye image and the left eye image of the 3D picture.
