1. A projector comprising:
first to third display elements each of which spatially modulates incident light to display an image; a first light source unit that includes a red light source that emits red light having a peak wavelength in a red wavelength band, the red light emitted from the red light source being applied to the first display element; a second light source unit that includes a first green light source that emits first green light having a peak wavelength in a green wavelength band, the first green light emitted from the first green light source being applied to the second display element; a third light source unit that includes a second green light source that emits second green light having a peak wavelength in the green wavelength band and a blue light source that emits blue light having a peak wavelength in a blue wavelength band, the second green light emitted from the second green light source and the blue light emitted from the blue light source being applied on the same optical path to the third display element; a color synthesizing means unit that synthesizes the images displayed by the first to third display elements; a projection lens that projects the image synthesized by the color synthesizing unit; and a control unit that controls, based on an input video signal, display operations of the first to third display elements and lighting operations of the red light source, the first and second green light sources, and the blue light source, wherein the control unit lights, for a predetermined period, the red light source and the first green light source to display a red image based on the input video signal by the first display element and a green image based on the input video signal by the second display element, wherein the control unit lights, for a first period, the second green light source to display the green image by the third display element, and lights, for a second period, the blue light source to display a blue image based on the input video signal by the third display element, the first and second periods being provided by dividing the predetermined period with a predetermined ratio, and wherein the second and third display elements simultaneously display the green image during the first period. |
