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

An image processing device and a projection system including 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 at least two kinds of light that are of a first color and a second color; the image processing device is used for acquiring and analyzing image data inputted by each frame, and adjusting based on the grayscale value of the inputted image satisfying a predetermined condition; the light valve is used for modulating the light emitted by the light emitting device, on the basis of the grayscale value 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...
