Abstract: A projection system includes an invisible light projector, a background member, an imaging unit, an image generator, and a visible light projector. The invisible light projector projects a predetermined invisible light image onto the object via invisible light. The background member is disposed behind the object in a direction of the invisible light emitted from the invisible light projector. The imaging unit captures an image of the invisible light projected from the invisible light projector. The image generator measures a shape of the object based on the image captured by the imaging unit to generate image data showing image content for projection onto the object in accordance with the measured shape. The visible light projector projects the image content shown by the image data onto the object via visible light. The background member has a light shielding surface that does not diffusely reflect the invisible light incident thereon.

Abstract: A projection device viewpoint image of a three-dimensional projection target is acquired, a three-dimensional model corresponding to the projection target is prepared as projection contents, the three-dimensional model is converted into a two-dimensional image that coincides with the projection device viewpoint image, and the two-dimensional image that coincides with the projector viewpoint image is projected to the projection target.

Abstract: A high-speed display device inputs first video information having a first frame rate and a gradation of first number of bits, generates a set of M (integer of 2 or more) variation gradation values having a second number of bits smaller than the first number of bits and having a sum corresponding to the respective gradation values of the gradations of the first number of bits, and distributes the values from the set of the M variation gradation values corresponding to the respective gradation values of the first video information obtained from a variation gradation value output to the corresponding M frames for each frame of the first video information to generate second video information having a second frame rate that is M times the first frame rate and display video based on the second video information.
