Light source device having first light source, second light source, and control section to control drive timing of first light source and second light source such that drive pattern of second light source is inversion of drive pattern of first light source, and projection apparatus and projection method which utilize said light source device

摘要

A light source device includes a first light source configured to emit light within a first wavelength band, a second light source configured to emit light within a second wavelength band, and a light source control section configured to control drive timing of the first light source with a first drive pattern, and to control drive timing of the second light source with a second drive pattern which is an inverted pattern of the first drive pattern of the first light source, such that a light emission period for light-source light using light emitted by the second light source is positioned between light emission periods for the light-source light emitted by the first light source, and such that a frequency of the light-source light using light emitted by the second light source is higher than a frequency of light emitted by the first light source.
