A method for controlling a projector including a light source, the method including identifying the state of the light source, generating a correction parameter based on the state of the light source, and correcting an image projected from the projector based on the correction parameter.

Projector, method for controlling projector, and information processing apparatus

A third controller of a control device executes obtaining a taken image obtained by imaging an operator, making a projector display a first display image including the taken image, detecting an operation gesture corresponding to processing to be executed by the control device from the taken image, generating a second display image based on the operation gesture, and making the projector display the second display image.

Control method of control device, control device, and display system

A projector includes a projection section, a spectral imaging section, and a control section, wherein the control section makes the projection section project an adjusting image corresponding to a color and a gray level of an image to be projected by the projection section while changing the color and the gray level to a first color and a first gray level, the first color and a second gray level, a second color and a third gray level, and the second color and a fourth gray level, sets a measurement condition corresponding to the color to the spectral imaging section, and makes the spectral imaging section take the adjusting images projected by the projection section to obtain spectral imaging data.

Projector, display system, image correction method, and colorimetric method

An electronic field enhancement element includes: a metal layer; a dielectric layer provided on the metal layer; and a plurality of fine metal structures provided on the dielectric layer. A refractive index n of the dielectric layer satisfies n'=n+i&#x3ba; and is in a range of 1&#x2266;n&#x3c;1.46, wherein a complex refractive index of the dielectric layer is n&#x2032;, an imaginary unit is i, and an extinction coefficient is &#x3ba;.
