摘要： A projection system having a first projection device and a second projection device is provided. The first projection device communicates with the second projection device to receive a first reception image, projects the first reception image onto a first projection target, captures a range including the first projection target, generates a first transmission image by removing, from a captured image of the first projection target, an image overlapping the first reception image, and transmits the first transmission image to the second projection device. The second projection device communicates with the first projection device to receive a second reception image, projects the second reception image onto a second projection target, captures a range including the second projection target, generates a second transmission image by removing, from a captured image, an image overlapping the second reception image, and transmits the second transmission image to the first projection device.

摘要： A projector includes a light source, a Fresnel lens group parallelizing the beam output from the light source, a light-incident-side polarizer transmitting the beam having exited out of the Fresnel lens group, a light modulator modulating the beam having passed through the light-incident-side polarizer to form a projection image, a light-exiting-side polarizer transmitting the beam modulated by the light modulator, and a projection lens projecting the beam having passed through the light-exiting-side polarizer. The Fresnel lens group includes a first Fresnel lens having positive power and disposed at a position closest to the light source in the Fresnel lens group, and a second Fresnel lens having positive power and disposed at a position shifted from the first Fresnel lens toward the light modulator. The light incident surface of the first Fresnel lens has a Fresnel surface. The light exiting surface of the first Fresnel lens has no Fresnel surface.

摘要： A projector includes a light source, a lens group that parallelizes the beam output from the light source, a light-incident-side polarizer that transmits the beam having exited out of the lens group, a light modulator that modulates the beam having passed through the light-incident-side polarizer to form a projection image, a light-exiting-side polarizer that transmits the beam modulated by the light modulator, and a projection lens that projects the beam having passed through the light-exiting-side polarizer. The light modulator includes first sub-pixels on which blue light is incident, second sub-pixels on which green light is incident, and third sub-pixels on which red light is incident. The lens group includes two lenses each having positive power. The two lenses each have a convex surface.

摘要： A projection system includes a first and second optical system including an optical element and disposed at the enlargement side of the first optical system. The optical element has a first transmissive surface, a reflection surface, and a second transmissive surface. The second transmissive surface has a convex shape an aspheric shape. An effective light ray range of the second transmissive surface has a first end close to an optical axis of the reflection surface in a first axis direction along a first axis perpendicular to the optical axis and a second end far from the optical axis. A first radius of curvature at the first end is greater than a second radius of curvature at the second end, and a first center of curvature of the first radius of curvature is farther than a second center of curvature of the second radius of curvature from the first end.
