Patent Searching and Data


Title:
PROJECTOR AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2012/081308
Kind Code:
A1
Abstract:
The present invention provides a projector which can solve the problem of low light use efficiency. A screen (10) has color stripes disposed at intervals, said color stripes generating visible light corresponding to inputted light. A laser light source unit (11) outputs an optical beam. A laser scanning unit (12) scans areas where the color stripes are disposed on the screen (10) with the optical beam outputted from the laser light source unit (11). A light detecting unit (13) detects feedback light from the screen (10) with respect to the optical beam. A control unit (14) adjusts light emitting timing and light emitting period of the laser light source unit (11), on the basis of detection results obtained from the light detecting unit (13), and has the optical beam outputted from the laser light source unit (11) such that optical pulses are inputted within each of the color stripes.
