Title:
OPERATION METHOD FOR CONTROL UNIT, CONTROL METHOD FOR PROJECTOR, AND PROJECTOR
Document Type and Number:
Japanese Patent JP2021101204
Kind Code:
A
Abstract:
To provide a technique to generate color correction data for adjusting the color of a projection image.SOLUTION: An operation method for a control unit that controls a projector includes: causing the projector to project a first image generated by red light, green light, and blue light on a display surface; generating brightness information representing the brightness of the red light, green light, and blue light, based on imaging data generated by an image pick-up device picking up the first image on the display surface through a band pass filter that passes the red light, green light, and blue light separately; and generating color correction data for correcting the color of the image projected by the projector based on the brightness information. The band pass filter includes a first band pass filter that passes the red light, a second band pass filter that passes the green light, and a third band pass filter that passes the blue light, and a wavelength region of the light passing through the first band pass filter, a wavelength region of the light passing through the second band pass filter, and a wavelength region of the light passing through the third band pass filter are separated from each other.SELECTED DRAWING: Figure 10
