Classification: CPC G  H | IPC G  H

Claim 4:
5. The projection system according to claim 4, wherein each of the plurality of sections of one of the plurality of micromirror units modulates image light of a pixel corresponding to the section in different modulation periods, and one section of the plurality of sections of each of the plurality of micromirror units of the light modulation device is configured to modulate image light in one same modulation period;
wherein from one modulation period to a next modulation period, the light deflecting device is configured to deflect one of the one or more illumination sub-beams from one section to a next section of the plurality of sections of one of the plurality of micromirror units; and
wherein the projection system further comprises a processing device, the processing device is configured to extract, from the image data, data of a pixel corresponding to a section of the light modulation device that modulates image light in a same modulation period, as image data corresponding to one modulation period, so as to obtain image data corresponding to each modulation period required for modulating the image by the light modulation device, and the processing device is further configured to provide the light modulation device with corresponding image data in each modulation period when the light modulation device is modulating the image, such that each of the plurality of micromirror units of the light modulation device modulates the image light in different modulation periods based on the corresponding image data, wherein image data obtained by the light modulation device in one modulation period comprises image data of a pixel corresponding to an irradiated section of the light modulation device in the one modulation period.
