A second projector disposed so as to be opposed to a projection surface includes a projection section configured to project second image light on the projection surface on which a base image is displayed, and visibility of the base image on which the second image light is projected is made lower than in a state in which the second image light is not projected on the projection surface.

Projector that lowers visibility of base image, projection system and projection method

A projection apparatus including a light source section, a projection section that projects light outputted from the light source section, and a control section that acquires captured image data produced by an imaging section, identifies a region of a projection target contained in the acquired captured image data and an image captured position of the region in the captured image data, determines a projection range over which the projection section projects light and a wavelength band of the light to be projected over the projection range based on the identified region and image captured position, and controls the projection section to cause the projection section to project light in the determined wavelength band over the determined projection range.

A display system includes a remote controller that includes a communication unit that transmits operation data to a projector, and an operation unit that receives an operation. The projector includes a remote controller light receiving unit that receives the operation data transmitted from the remote controller, a communication I/F unit that communicates with projectors, and a display unit that displays one setting screen selected from among a plurality of setting screens constituting a hierarchical structure in a case where the display unit is selected as an object to be set by the remote controller. The projector transmits an item identifier indicating a hierarchy of the setting screen being currently displayed to the projectors in a case where a switching instruction for switching an object to be set to the projectors is received from the remote controller during the display of the setting screen.

An image display apparatus includes a display section (display unit) that displays an image, an information acquisition section that acquires predominance levels of sympathetic nerves and parasympathetic nerves and an activity magnitude of the autonomic nerves based on the biological information, an image generation section that generates the biological state image in which a figure having a size according to the acquired activity magnitude of the autonomic nerves is set along a first axis, along one side of which the predominance level of the sympathetic nerves is set with respect to a reference point and along the other side of which the predominance level of the parasympathetic nerves is set with respect to the reference point, in a position according to the acquired predominance levels of the sympathetic nerves and the parasympathetic nerves.
