摘要： 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.

摘要： A projection control device includes: a communication unit connected to communicate with an image capturing device configured to capture an image of a target object positioned around a projected object; a derivation unit configured to derive a projection position of a content image based on designation of a parameter related to the content image to be projected onto the projected object and an image of the projected object including the target object; a projection image generation unit configured to generate a projection image including the content image disposed at the derived projection position; and a control unit configured to transmit a projection instruction of the projection image to a projection device via the communication unit.

摘要： A projection system for projecting an image comprises: a visible light projector that projects the image with visible light; an invisible light projector that projects an invisible light image onto the object with invisible light; an imaging device that captures the invisible light image projected from the invisible light projector; and a controller that obtains information regarding reflected light from the object while obtaining three-dimensional measurements of the object to control the image, based on a capture image. The invisible light image includes a bright region and a dark region having a light amount less than the light amount of the bright region. The invisible light projector emits the invisible light to cause the light amount of the dark region in the invisible light image to be more than or equal to an offset value.

摘要： A motion sensor device according to an embodiment of the present disclosure includes an image sensor (101) and LED light sources (102, 103). Using an image captured by the image sensor (101) when both of the LED light sources (102, 103) are turned ON and an image captured by the image sensor (101) when only the LED light source (103) is turned ON, the distance to an object is estimated based on the luminance ratio of the object.

摘要： 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.

摘要： 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.

摘要： Provided is a real-time-measurement projection device which can measure a distance to a changing target object in real time, and, particularly, can appropriately perform projection and mapping on a changing target object. A real-time-measurement projection device includes a projection device that projects pattern light including a pattern image onto a projection target, an imaging device that electronically acquires a captured image of the projection target irradiated with the pattern light for each pixel for a predetermined exposure time, and a calculation device that calculates a distance to each point of the projection target by contrasting data of the captured image with data of the pattern image, in which the imaging device temporally deviates a start point and an end point of the predetermined exposure time for each pixel.
