Document Type and Number:
Japanese Patent JP7326742
Kind Code:
B2
Abstract:
To improve color measurement accuracy and image correction accuracy.SOLUTION: A projector 100 executes an imaging step of capturing an adjustment image in a wavelength range set on the basis of the image by a spectral imaging unit 137 while changing the spectral wavelength of a spectroscopic element 302 for each first wavelength interval to generate imaging data, a calculation step of calculating an estimated value of a spectrum for each second wavelength interval shorter than the first wavelength interval on the basis of spectral imaging data generated by the imaging step, and an estimation matrix M used to estimate the spectrum, and a generation step of generating a correction parameter for correcting image data which is the source of an image displayed by the projector 100 on the basis of the estimated value of the spectrum calculated by the calculation step.SELECTED DRAWING: Figure 1
