A parameter adjusting method is applied to a projector having an ambient light sensor, a database and a digital micromirror device. The parameter adjusting method includes analyzing a detection signal generated by the ambient light sensor to acquire an environmental light datum, comparing the environmental light datum with a lookup table of the database to compute at least one compensation parameter, and adjusting an amount of reflection light generated by the digital micromirror device in accordance with the at least one compensation parameter for controlling the projector to output a calibrated projection image in response to compensation of the environmental light datum.

A control apparatus includes a control unit that adjusts at least one of a color and luminance of a projection image for each group of the plurality of projection apparatuses based on information on the group and a captured image obtained by imaging projection images of the plurality of projection apparatuses using the pickup apparatus. The control unit acquires each of positions of a plurality of projection areas of the plurality of projection apparatuses based on the captured image, and generates, as the information on the group, information indicating that two projection apparatuses corresponding to a first projection area and a second projection area belong to the same group in a case where a distance between the first projection area and the second projection area among the plurality of projection areas is smaller than a predetermined threshold.

A method of controlling a projector includes projecting an achromatic area image representing a drawing area in which the projector receives drawing using a pointer on a projection surface at a first luminance at a ratio on the projection surface, the ratio being smaller than or equal to a specific ratio to a maximum luminance at which the projector capable of project an image on the projection surface, detecting a position on the projection surface pointed by the pointer while projecting the area image, determining whether or not the position is included in the drawing area, and displaying, by the projector, an area including at least a part of an outline of the drawing area at a luminance higher than the first luminance when it is determined that the position is included in the drawing area.

Light projection systems and methods may comprise combining light from two or more projectors. Each projector may be controlled so that the combined light output of the projectors matches a target for the projected light. In some embodiments optimization is performed to generate image data and control signals for each of the projectors. Embodiments may be applied in image projecting applications, lighting applications, and 3D stereoscopic imaging.

A system allows a user to select designs for apparel and preview these designs before manufacture. The previews provide photorealistic visualizations in two or three dimensions, and can be presented on a computer display, projected on a screen, or presented in virtual reality (e.g., via headset), or augmented reality. The system can also include a projection system that projects the new designs onto garments on mannequins in a showroom. The garments and the new designs projected onto the garments have a three-dimensional appearance as if the garments having the new designs are worn by people. Software and lasers are used in finishing the garments to produce garments with the new designs and the finished garments have an appearance of the three-dimensional appearance of the garments and new designs on the mannequins with the new designs projected onto the garments by the projection system.

Methods and systems are described for condition mitigation. A computing device may display content. The computing device may determine that displaying and/or outputting the content may impact a person with a condition. The computing device may take an action to reduce an impact of the content on the person.

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 method for producing visual immersion effects for audiovisual content and sound content associated with the video image, the method including the steps of extracting a background of a video image from the audiovisual content; selecting an end zone located at one end of the extracted background; determining a semantic state from the sound content associated with the video image, and processing a predefined image in the selected end zone to generate at least one visual frame intended to be displayed in the peripheral field of vision of a viewer while the video image is being projected in the central field of vision of the viewer, the processing of the predefined image being linked to the semantic state determined from the sound content.

A light projection system includes a MEMS mirror operating on a mirror drive signal to generate a mirror sense signal resulting from operation of the MEMS mirror based on the mirror drive signal. A mirror driver generates the mirror drive signal from a drive control signal. A controller receives the mirror sense signal from the MEMS mirror, obtains a first sample of the mirror sense signal at a first phase thereof, obtains a second sample of the mirror sense signal at a second phase thereof, wherein the first and second phases are separated by a half period of the mirror drive signal, with the second phase occurring after the first phase, and generates the drive control signal based on a difference between the first and second samples to keep the mirror drive signal separated in phase from the mirror sense signal by a desired amount of phase separation.

A projection apparatus projects an image on a screen based on input data including information on absolute luminance. The projection apparatus includes: a peak luminance value acquisition unit configured to acquire a peak luminance value on the screen when the projection apparatus projects an image on the screen at a maximum output gradation value; a reference luminance value setting unit configured to set a reference luminance value to be higher than the peak luminance value; a relation information setting unit configured to set, based on the reference and peak luminance values, relation information indicating a relation between an output gradation value and a light output value for displaying an output image; an output gradation value setting unit configured to set an output gradation value based on the input data and the relation information; and an output control unit configured to output an image based on the output gradation value.
