Problems solved by technology

[0002] In the known technology, the optical mechanism of the projection system is mostly fixed, and even if it can be changed, it is limited. Changing among several preset modes, but unable to meet the actual variety of projection environments
In particular, the effect of projecting images in a high-brightness environment is obviously lower than that of projecting in a dark room
In addition, known projection systems cannot dynamically adjust the white balance of the image

Embodiment Construction

[0032] The invention discloses a projection device for generating projection images on objects. In order to make the narration of the present invention more detailed and complete, refer to the following description and cooperate Figure 1 to Figure 5 schema.

[0033] refer to figure 1 , is a block diagram of a projection device 100 according to an embodiment of the present invention. For example, besides being a single projector, the projection device 100 can also be integrated into a personal computer, a notebook computer, a personal digital assistant, a mobile phone or a mobile audio-visual device.

[0034] The projection device 100 includes a sensing unit 102 , a control unit 104 , a light source module 106 and an optical processing unit 108 . Wherein, the sensing unit 102 generates the sensing signal SS. Preferably, the sensing unit 102 is an image capture device (such as a CCD camera or a CMOS camera), so as to capture and record the projected image PI projected on th...

Abstract

The invention provides a projection device for projecting images on an object. The projection device comprises a sensing unit, a control unit, a light source module and an optical processing unit, wherein the sensing unit generates a sensing signal; the control unit is coupled to the sensing unit and generates a control signal according to the sensing signal; the light source module outputs polychromatic light and adjusts the polychromatic light according to the control signal; and the optical processing unit receives the polychromatic light output by the light source module to generate a projection image.

Description

technical field [0001] The present invention relates to a projection device, in particular, the projection device adjusts the projection image according to different external environment light sources or according to different projection areas. Background technique [0002] In the known technology, the optical mechanism of the projection system is mostly fixed, and even if it can be changed, it is limited. There are several preset modes, which cannot meet the actual various projection environments. In particular, when projecting in a high-brightness environment, the effect of the image is obviously lower than that in a dark room. In addition, the known projection system cannot dynamically adjust the white balance of the image. [0003] In view of this, there is a need for a projection device that can automatically adjust with the external environment or the image of the projected area. In addition to adjusting the brightness, it can also adjust the white balance. Content...
