Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be specifically described below in conjunction with the drawings in the embodiments of the present invention.

[0027] see figure 1 , figure 1 It is a schematic diagram of the projection system 100 in the first embodiment of the present invention. An embodiment of the present invention provides a projection system 100 , which includes a light emitting device 10 , a light valve 20 , an image processing device 30 and a projection lens 40 . The light emitting device 10 is used for emitting and providing light for display, wherein the light emitting device 10 at least provides light of a first color and light of at least one second color. The light valve 20 is used for selectively providing light to the projection lens 40 under the control of the image processing device 30 for image display. In this embodiment, the projection system 100 also includes necessary or unnecessary structural features such...

Abstract

The invention relates to an image processing device and a projection system including the same. The image processing device comprises a light emitting device, an image processing device and a light valve; the light-emitting device is used for emitting light at least in first and second colors; the image processing device is used for obtaining and analyzing each frame of input image data and adjusting a grey-scale value in an input image which meets a preset condition; and the light valve is used for modulating the light emitted by the light emitting device based on the grey-scale value which is adjusted by the image processing device to form a display image.

Description

technical field [0001] The invention relates to the field of projection technology, in particular to an image processing device and a projection system. Background technique [0002] Existing projection systems generally include a light emitting device, a light valve, and an image processing device. The light emitting device emits light of three colors: red, green, and blue. color light and modulate the image according to the input image data. However, the light-emitting device often suffers from insufficient light of a certain color (such as insufficient red light) due to reasons such as poor phosphor efficiency and aging, which affects the projected picture effect of the projection system. Contents of the invention [0003] In order to solve the technical problem of poor projected picture effect of the prior art projection system, it is necessary to provide an image processing device with better picture effect. [0004] Further, a projection system including the aforem...
