Projector for projecting a multi-colored image

Projector for projecting a multi-colored image, comprising:

• several color channels in order to generate color subframes of the multi-colored image to be projected,
• wherein each color channel comprises
• a first modulator, comprising several first pixels that are controllable independently of each other in order to modulate light from a light source by which the first modulator can be impinged;
• an imaging optical system;
• and
• a second modulator, comprising several second pixels that are controllable independently of each other, which can be impinged by the light modulated by the first modulator via the imaging optical system and modulate the light via the second pixels in order to generate a color subframe,
• a control unit that actuates each color channel with reference to fed-in image data such that one of the color subframes of the multi-colored image to be projected is generated;
• and
• a projection optical system that images the generated color subframes onto a projection surface such that the color subframes can be perceived as the multi-colored image to be projected,
• wherein each color channel is formed for the generation of a color subframe of a predetermined base color,
• wherein at least one of the color channels has a wavelength-dependent contrast which leads to a variation of a color space location of the predetermined base color with the lightness to be generated, and
• wherein the control unit controls each color channel such that, for at least one picture point in the multi-colored image, which is to comprise a predetermined target color space location and a predetermined target lightness according to the image data, the color space location shift of the predetermined target color space location caused by the color channel or the color channels is compensated for by compensating the wavelength-dependent contrast while retaining the target lightness.
