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.

An image display device according to disclosed one aspect comprises: a plate for detecting the weight of food ingredients; a projector for projecting images onto the plate; a camera for capturing food ingredients and user inputs relative to the images projected; and a controller for controlling the projector so that the changed images are outputted in response to the user inputs or changes in weight of the food ingredients.

Based on information about a vehicle, the information can be projected and displayed onto a road surface or the like. An image projection apparatus, which projects an image, includes an acquisition unit that acquires the information about the vehicle, and an image projection unit that projects the image based on the information acquired by the acquisition 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 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.

[Problem] An information processing apparatus, an information processing method, and a recording medium with which a user can recognize a boundary of a drivable range by feedback for a projection specification position by the user to facilitate determination of and search for a projection position are provided. [Solution] The information processing apparatus includes a controller configured to perform processing of outputting feedback indicating an effect corresponding to a boundary of a drivable region of a drive-type projector in a projection environment space in accordance with a state of a projection specification position specified by a user for the drivable region, the state being determined based on the drivable region and the projection specification position.

A signal detection device of the present invention includes a first control unit configured to determine whether there are inputs of a plurality of external signals connected thereto, a second control unit configured to be activated after the first control unit is activated, a first input unit connected directly to the first control unit and configured to input a first external signal, which is one type of the plurality of external signals, and a second input unit connected to the first control unit via the second control unit and configured to input a second external signal, which is another type of the plurality of external signals, and the first control unit determines whether there is an input of the first external signal before the second control unit is activated and determines whether there is an input of the second external signal after the second control unit is activated.

An augmented reality system may include a data gathering device configured to collect data regarding an environment exterior to the vehicle. In addition, the system may include a vehicle controller including a device processor and a non-transitory computer readable medium including instructions, executable by the processor, for performing the following steps: receiving data from the data gathering device; and transmitting information to a set of augmented reality goggles in order to facilitate a projection of a modified view of an interior of the vehicle based on the data collected regarding the environment exterior to the vehicle.

An image display system includes a projector projecting image light onto a projection surface, at least one camera picking up at least one image of the projection surface and thus acquiring at least one picked-up image, at least one microphone detecting a sound generated in an image pickup range of the camera, and a control device controlling a position or an orientation of an image displayed on the projection surface by the image light, based on the at least one picked-up image, when a target sound is detected based on the sound.
