Abstract: A content generation method generates image content to be projected at a projection position in a real space by a projector. In a first acquisition process, space information regarding a virtual space corresponding to the real space is acquired. In a second acquisition process, display position information regarding a display position corresponding to the projection position in the virtual space is acquired. In a third acquisition process, reference position information regarding a reference position in the virtual space is acquired. In a generation process, an image including an object viewed from the reference position when the object is displayed at the display position in the virtual space is generated as the image content, based on the space information, the reference position information, and the display position information.

Abstract: A projection adjustment program which causes a computer to execute a process relating to adjustment of projection operations of a plurality of projection devices configured to perform position measurement and projection on a target object in a projection system including the plurality of projection devices. The process includes: causing a projection device to project measurement light onto the target object; causing an image capture device to receive reflection light of the measurement light, the reflection light being reflected from the target object; judging a connection relationship of a projection range of the projection device on a basis of the received reflection light of the measurement light; executing a process of the judging of the connection relationship on all processing target projection devices; generating projection position information indicating a connection relationship between projection ranges of the respective projection devices of the projection system; and displaying the generated projection position information on a display.

Abstract: A projection type image display apparatus includes an adjusting sub-frame image generator and a shift amount adjuster. The adjusting sub-frame image generator generates a primary adjusting sub-frame image having a design in which a first line having a first color and a width of an N pixel (N being a natural number) is displayed on a background image having a second color, and a secondary adjusting sub-frame image having a design in which a second line having a third color and a width of an M pixel set to N=M+α (M being an integer equal to or greater than 1, α being an integer equal to or greater than 0) is displayed on a background image having a fourth color. The shift amount adjuster adjusts the shift amount when the display positions of the primary and secondary adjusting sub-frame images on the projection surface are shifted relatively to each other.

Abstract: A projection video display apparatus includes: a converter that converts an input video signal having a first number of pixels and a first frame rate into a conversion video signal having a second number of pixels and a second frame rate, the second number of pixels being smaller than the first number of pixels, and the second frame rate being an n-th multiple (n is an integer of 2 or greater) of the first frame rate; an optical element that displaces an optical axis of the video light beam; an optical element driving unit that drives the optical element at a frequency F being a natural-number multiple of the first frame rate; and a rotating body that rotates at a rotation speed R. The rotation speed R is set so as to become a value within a predetermined range corresponding to the frequency F.
