Luminous intensity.
The image display control method of the projection device 1320 is introduced below, wherein it is understood that following main
The part different from first embodiment is introduced, identical part repeats no more.
Specifically, the modulation period (i.e. a wavelength convert cycle T) of one frame image of the progress of optical modulator module 1340 includes
Three different periods, respectively the first sub-frame images modulate period T1, the second sub-frame images modulate period T2, third subframe
Image modulation period T3, the optical modulator module 1340 are based on second color in first sub-frame images modulation period T1
Data-signal carries out image modulation to first stimulated light and generates the second color image light, in second sub-frame images modulation
Period T2 be based on the third color data signal to second stimulated light carry out image modulation generate third color image light,
The first color data signal is based in third sub-frame images modulation period T3 to carry out first part's exciting light

Value is A, B, C, provides first part's exciting light of the optical modulator module 1340, first stimulated light and described the
The brightness of two stimulated lights is respectively a, b, c, and the brightness that the light source controller 1319 controls the infrared light to provide to institute
Stating brightness of the infrared light of optical modulator module 1340 in three subframes image modulation period is respectively d, e and f, wherein d=
α*a；E=α * b；F=α * c, i.e., the described infrared light provided to the optical modulator module 1340 are modulated in three subframe pictures

C*c)=α (A*d+B*e+C*f), so that the grayscale of the infrared light image and visible images that generate matches.
For example, if described first into third data-signal any one pixel signal value A, B, C be (50,40,
30), then its estimated brightness is Y=50*a/255+40*b/255+30*c/255.If being come using the signal value (50,40,30)
Infrared light is controlled, to guarantee that pixel intensity is undistorted, needs to guarantee pixel intrinsic brilliance value Y '=50*d/255+40*e/255+
30*f/255, and d=α a, e=α b, f=α c, so obtain, the actual pixels brightness value Y '=α (50*a/255+40*
B/255+30*c/255), i.e., the corresponding brightness of infrared light is α times of visible light, may make the brightness value of each pixel equal in this way

Sub-frame images modulate the period) brightness L3 is minimum, in feux rouges section the brightness L1 of (the first sub-frame images modulate the period) L3 with
Between L2, i.e. L3<L1<L2.
