  • Patent number: 11323673
    Abstract: A method for operating a control apparatus that controls a projector includes causing the projector to project a first image on a display surface, generating brightness information based on captured image data generated by causing an image sensor to capture an image of the first image on the display surface via a bandpass filter, and generating color correction data for correcting the colors of an image projected by the projector based on the brightness information. The bandpass filter includes a first bandpass filter that transmits the red light, a second bandpass filter that transmits the green light, and a third bandpass filter that transmits the blue light, and the wavelength region of the light that the first bandpass filter transmits, the wavelength region of the light that the second bandpass filter transmits, and the wavelength region of the light that the third bandpass filter transmits are separate from one another.

  • Patent number: 10928250
    Abstract: A projector includes a measurement unit, a correction parameter generation unit, and an image processing unit. The measurement unit measures a color of an image formed on a projection surface in terms of a plurality of colors constituting an RGB color system and at least one color constituting an XYZ color system. The correction parameter generation unit generates a correction parameter based on a conversion value and a second measurement value of the color, which is measured by the measurement unit among the colors constituting the XYZ color system. The conversion value is obtained by converting a first measurement value of the color in the RGB color system, which is measured by the measurement unit, into the color in the XYZ color system. The image processing unit corrects image light with the correction parameter.
