Title:
PROJECTION DEVICE AND COLOR GAMUT ADJUSTMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2019/144494
Kind Code:
A1
Abstract:
Provided in the present application are a projection device and a color gamut adjusting method thereof. The projection device comprises a light source device and a control device. The light source device is used for emitting a first primary color laser, a second primary color laser, a third primary color laser, and a fourth mixed color fluorescent according to an instruction. The control device is configured to determine a color gamut range of pixels of a to-be-modulated image, and to control the light source device to output the light required to modulate the to-be-modulated image in the first primary color laser, the second primary color laser, the third primary color laser, and the fourth mixed color fluorescence, according to the color gamut range. The first primary color laser, the second primary color laser, and the fourth mixed color fluorescence are capable of modulating an image within a first color gamut. The first primary color laser, the third primary color laser, and the fourth mixed color fluorescence are capable of modulating an image within a second color gamut. The first color gamut range and the second color gamut range are combined into a continuous color gamut range. The present application is capable of modulating an image with a wide color gamut, and also saves light source energy.
