Title:
投影装置、投影方法及びプログラム
Document Type and Number:
Japanese Patent JP5408278
Kind Code:
B2
Abstract:
A projection unit (17) projects the optical image formed by the optical image formation unit (13-16, 28) toward a projection target. A temperature detection unit (29-31) detects a temperature of each type of the semiconductor light emitting elements (18, 26, 27) during light emission. A measurement unit (28) measures an intensity of light from each type of the semiconductor light emitting elements (18, 26, 27) during light emission. A light emission control unit (34) (a) corrects a measurement result from the measurement unit (28) using a detection result from the temperature detection unit (29-31) and (b) controls the light emission intensity for each of the semiconductor light emitting elements (18, 26, 27) based on the corrected measurement result.
