An image projection apparatus includes a first light source configured to emit first light with a first wavelength band, a wavelength conversion element configured to convert part of the first light into wavelength-converted light with a wavelength band different from the first wavelength band and containing a second wavelength band, a second light source configured to emit second light with a wavelength band contained in the second wavelength band, a first measurement unit configured to measure a light quantity in a first measurement wavelength band as at least part of the second wavelength band, and an acquisition unit configured to acquire information on a light quantity of the first light and a light quantity of the second light by using a measurement result by the first measurement unit.
An image projection apparatus configured to project a projection image derived from modulated light, the image projection apparatus comprising:
A control method for an image projection apparatus including a first light source configured to emit first light with a first wavelength band, a wavelength conversion element configured to convert part of the first light into wavelength-converted light with a wavelength band different from the first wavelength band and containing a second wavelength band, a second light source configured to emit second light with a wavelength band contained in the second wavelength band, and a light modulation element configured to modulate light from the first light source and the second light source, the control method comprising:
A non-transitory computer readable storage medium for storing a computer program that enables a computer to execute a control method for an image projection apparatus including a first light source configured to emit first light with a first wavelength band, a wavelength conversion element configured to convert part of the first light into wavelength-converted light with a wavelength band different from the first wavelength band and containing a second wavelength band, a second light source configured to emit second light with a wavelength band contained in the second wavelength band, and a light modulation element configured to modulate light from the first light source and the second light source, the control method comprising:
