The disclosure provides a method for adjusting pixel values of blending image. The method includes projecting, on a projection surface, a first projection image onto a first projection range and a second projection image onto a second projection range by a first projector and a second projector, and blending the first projection image and the second projection image to generate a blending image; calculating positions of a plurality of boundaries of the first projection range and the second projection range; adjusting a range of an overlapping area between the first projection range and the second projection range; and adjusting image parameters of a non-overlapping area outside the overlapping area, to enable pixel values of the non-overlapping area to be close to pixel values of the overlapping area.

An object feature visualization system may include a computing device that generates video-mapped images to project onto physical objects. The video-mapped images may include features to be projected onto the objects. The projection of a video-mapped image onto the physical object allows for the visualization of the feature on the object. In some examples, the computing device receives a feature selection for a particular object, and generates a video-mapped image with the selected feature to provide to a projector to project the video-mapped image onto the physical object. In some examples, a user is able to select one or more features for one or more objects of a room display via a user interface. The system then projects video-mapped images with the selected features onto the physical objects. The system may allow a user to save feature selections, and to purchase or request additional information about objects with selected features.

A projector and a projection method are provided. The projector includes a control device, a projection optical engine, a distance sensing device, and an image capturing device. The projection optical engine projects a first projection image to a projection surface according to first image data. The distance sensing device senses multiple distance parameters of a projection area. The image capturing device captures the first projection image to obtain a first captured image. The control device performs a keystone correction operation and a leveling correction operation on the first image data. The projection optical engine projects a second projection image to the projection surface according to the corrected first image data. The control device obtains a second captured image including the second projection image through the image capturing device, and analyzes the second captured image to project current projection image size information in the second projection image.

A system and method for aligning projection of an optical indicia on a surface of a large object is disclosed. A reference is disposed in proximity to the object. The reference includes a plurality of markers spaced at intermittent locations. A projection system projects optical indicia onto the surface of the object. A detection system detects the markers disposed upon the reference and signals an image of the markers to a processor for the processor to register a location of the projection system relative to the reference. The reference is aligned with a feature disposed upon the object enabling registration of the markers to the object. A location of the projection system relative to the object is established enabling the projection system to project the optical indicia onto the object to a predetermined location.

A management information display system includes: a management state detecting unit configured to detect a placement state of an object placed on a predetermined placement area such that the object is able to be taken out; a projecting device configured to be capable of projecting a projection image onto the placement area; and a control device configured to: determine, based on a detection result from the management state detecting unit, whether or not the object has been taken out from the placement area; set projection information including information on the object that has been taken out, when the control device determines that the object has been taken out; and control the projecting device such that the projection image representing the projection information is projected onto a position where the object had been placed on the placement area.

There is provided a setting assistance apparatus including a touch panel, which includes a display apparatus, a camera, and a processor. The processor programmed to cause the camera to capture an image of a projection image projected by a projector on a target to generate a captured image, cause the display apparatus to display the captures image, superimposes a guide image that prompts execution of the operation of setting at least one of the position or size of the projection image on the captured image, and cause the display apparatus to display the superimposed image.

A display system includes a projector, an HMD, and an information processing device. The information processing device includes a processing device storage unit configured to store three-dimensional map data in which setting information in which a display position of an object is set and positional information indicating a position of a display surface are registered, and image data of an object image, and a processing control unit configured to select whether to display the object image on the projector or to display the object image on the HMD, based on a positional relationship between a position of the HMD notified from the HMD and the display position of the object, and transmit the image data of the object image to the projector or the HMD being selected.

An improvement in quality is achieved by improving a contrast ratio. Therefore, in a projector device including a light source device using a solid-state light source (AR) includes a temperature adjustment device (190) capable of setting a state in which a temperature of at least the solid-state light source is caused to increase. Then, a determination unit (12) determines a luminance state of an image and a control unit (16) controls a heat state of the solid-state light source (AR) by controlling the temperature adjustment device (190) on the basis of a determination result. In particular, by increasing the temperature of the solid-state light source (AR) in accordance with an image, light emission efficiency is lowered to decrease luminance.

A control device of a projection system includes one or more projection apparatuses that project a first image including a plurality of marker images, and an imaging apparatus that captures at least a part of the first image, the control device includes a processor, and the processor is configured to perform a control of projecting a second image including a plurality of marker images from the projection apparatus based on a capturing result of at least the part of the first image by the imaging apparatus.

A display method includes attenuating the brightness of an image corresponding to a superimposed area of a first image when the position of a projector is a reference position based on a first attenuation coefficient specified in accordance with the position in the superimposed area, calculating displacement information on displacement of the projector based on an output signal from an inertial sensor when the position of the projector is displaced from the reference position, obtaining a corrected first attenuation coefficient by correcting the first attenuation coefficient in accordance with the displacement information, and attenuating the brightness of the image corresponding to the superimposed area of the first image based on the corrected first attenuation coefficient when the position of the projector is displaced from the reference position.
