Title: PROJECTION SYSTEM, PROJECTION METHOD AND IMAGE DATA PROCESSING METHOD
Abstract:
A projection system (100, 200, 300, 400), a projection method and an image data processing method. The projection system (100, 200, 300, 400) comprises a light source device (110), an image data processing module (120) and a control and light modulation module (130). The light source device (110) is used for emitting first light and second light. The image data processing module (120) is used for determining the color gamut range of an image to be displayed. If the color gamut value of a portion of the pixels of the image to be displayed is within a first color gamut range (F1) and the color gamut value of another portion of pixels is outside the first color gamut range (F1), the image data of the image to be displayed is divided into first image data and second image data. The control and light modulation module (130) is used for modulating the first light according to the first image data so as to generate corresponding projection light and modulating the second light according to the second image data so as to generate corresponding projection light, or modulating the first light and the second light according to the second image data so as to generate corresponding projection light.
