Projector having a lamp that emits projection light to project a 3D picture

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.

主权项

1. A projector projecting a right eye image and a left eye image in a time division manner comprising:
a light source; 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 individually, to control the opened state or the closed state of the right eye shutter and the left eye shutter, and the right eye shutter being in an opened state in a first period and the left eye shutter being in an opened state in a second period; and a light source drive section that supplies a light source drive current to the light source in at least a part of the first period for projecting the right eye image and at least a part of the second period for projecting the left eye image.
