An object feature visualization system is disclosed. The 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 projection video display apparatus includes a video input unit, a light source, a display element, a projection optical system, and a variable light adjusting function which changes the amount of light incident on the display element. Display modes using the variable light adjusting function are prepared, and one display mode of the display modes can be selected from a menu screen. Further, the display modes of the display video using the variable light adjusting function includes: a first display mode where the input video is displayed while changing a light adjusting amount in accordance with light adjusting control information, which is input from external equipment and is capable of controlling the variable light adjusting function in unit of frame of a projected video; and a second display mode where the input video is displayed while changing a light adjusting amount in accordance with the input video.

A projection system and a projection method are provided. The projection system includes a processing module, a projection module and a photographing module. The projection module projects a first projection image based on a projection scope. The photographing module captures a part of the first projection image based on a photographing scope, so as to obtain a first photographic image. The part of the first projection image includes a plurality of first positioning grid points. The processing module analyzes the first photographic image, so as to obtain a plurality of first grid point coordinates. The processing module calculates a plurality of preset grid point coordinates corresponding to a plurality of preset positioning grid points in the whole projection scope one by one according to the first grid point coordinates. The processing module determines a projection result in the projection scope according to the preset grid point coordinates.

Correction performance is improved regarding a synthetic blur in which a plurality of blur characteristics is synthesized, for example, a focus blur that occurs in a superimposed projection image, or the like. An image processing device according to the present technology includes: a correction unit that obtains a plurality of blur-corrected images by performing blur correction processing on an input image regarding a focus blur that occurs in a projection image by an image projection device, by using a filter coefficient for blur correction corresponding to each of a plurality of blur characteristics, the filter each being obtained on the basis of the plurality of blur characteristics; and an image output unit that individually outputs the plurality of blur-corrected images obtained by the correction unit.

A multiplexed light field projector device and a multiplexed light field display to output a light field image is described. The projector has a projector base with a projection optical system configured to output light rays to form a projected image, a collimating optical system configured for collimation of the projected image light rays to form a second projected image, which is directed to a display optical system to produce a light field image. Light field projector devices or alternative projector devices may be used individually or in combination with one or more other projectors which can be arranged to form a multiplexed direct projection light field display. The arrangement of projector devices may have an individual or shared display optical system.

A projection system and a projection method are provided. The projection system includes a first projector and a second projector. A first projection image projected by the first projector and a second projection image projected by the second projector are partially overlapped. A projection region edit menu is executed to display multiple adjustment points and multiple connecting lines on the first projection image. A position of a selected adjustment point among the multiple adjustment points and positions of two connecting lines connected to the selected adjustment point among the multiple adjustment points displayed on the first projection image are changed according to a first moving instruction to select a closed region formed by the multiple connecting lines in a non-overlap region of the first projection image. The projection method is adapted to the projection system that provides a blending projection effect of multiple projectors having an even brightness.

An image projection method includes, projecting a plurality of first markers onto a screen, projecting one or more first sub-markers each having an exterior appearance different from an exterior appearance of each of the plurality of first markers onto the screen, determining positions of the plurality of first markers, determining positions of the first sub-markers, determining a shape of a contour of a first image projected on the screen based on the positions of the plurality of first markers, determining a first line and a first edge of a blend area where the first image and a second image different from the first image are mixed with each other based on the positions of the plurality of first markers and the positions of the first sub-markers, and the first line and the first edge forming the contour of the first image, and projecting the first image onto the screen.

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.

A system and method for the projection of virtual 3-D images onto a surface with perspective shifting viewing capability including: a source of data for at least two different paired left-right view sets of one subject, an image reflecting surface, and a projector capable of simultaneously projecting pairs of left-right view sets, and capable of changing projected left-right view sets of images from a first set to a second set to create a stereopsis effect in which content of a complete projected image appears to move in perspective.
