Abstract
The utility model discloses a projecting device with human eye protection function. The projecting device is characterized in that at least one image acquisition component is additionally arranged on a projector body, when projection information is projected to a display screen through the projector body, and the image acquisition component can capture the human-form image of a user, receives the human-form image by using an electric circuit arranged inside the projector body or an image processing unit arranged in an external electronic device, then generates a human-form black mask and outputs the human-form black mask, and the human-form black mask is projected to a display screen in the position corresponding to the user through the projector body. The human-form black mask can be generated through the projecting device, therefore, the eyes of the user can be prevented from direct intense light of the projector body, and the damage to the eyes can be also avoided.
Description
Technical field
The utility model relates to the improving technology field of projection arrangement, particularly a kind of projection arrangement with human eye defencive function.
Background technology
Along with development of information industry, the achievement Report of many academic research units, academic report, paper publishing etc., and every meeting of business circles, all often use the bulletin mode that motion, report achievement, achievement are described ... etc., therefore, bulletin is exactly to share all information with suitable multimedia show, add the present projector of universalness, allow bulletin generalize more.
Yet generally when using projector to make bulletin, the speaker is ready to the transparency content of giving a lecture usually in advance, in telling process, utilizes projector that film is play in order, and projection obtains on the display screen; Yet; the speaker can stand in before the display screen usually and face the audience; this moment, the speaker was in the anterior position in the face of projector's projection camera lens; when projector's projecting mirror hair ejaculation transparency image is shown in display screen; speaker's eyes are then facing to high light that projector launched; when the of short duration direct projection eyes of projector's high light; can feel dazzling and cause shadow to persist; but when projector's high light in the speech process during long-time direct projection eyes; then may cause permanent injury, be necessary to be on one's guard eyes.
In view of this, the utility model proposes a kind of projection arrangement that can have the protection human eye functions, make the speaker in the bulletin process, can avoid projector's high light direct projection eyes.
Summary of the invention
The utility model provides a kind of projection arrangement with human eye defencive function, can produce black mask, and with this black mask output corresponding position on display screen, to avoid projector's high light direct irradiation eyes, reaches the effect of effective protection human eye.
Another purpose of the present utility model is by a kind of projection arrangement with human eye defencive function being provided, can providing a comfortable not dazzling bulletin environment for the user.
For achieving the above object, projection arrangement of the present utility model comprises a projector body, is used for projection information is projected a display screen; At the projector body outer surface at least one image-pickup assembly is housed, is used to capture at least one user's image; Utilize an image process unit again, be used for after receiving this image, producing black mask, and export the opposite position of this black mask in display screen according to user's physical location.
Be explained in further detail below in conjunction with specific embodiments and the drawings, with understanding the purpose of this utility model, technology contents, characteristics that are more prone to and the effect that can realize thereof.
Description of drawings
Fig. 1 is a projection configuration diagram of the present utility model;
Fig. 2 is the humanoid black mask synoptic diagram that utilizes the utility model to produce.
Embodiment
The projection arrangement that the utility model proposes with human eye defencive function; can be according to the user position; produce black mask and be output in opposite position on the display screen, avoiding projector's high light direct irradiation eyes, and then reach the effect of protection human eye.
Because projector comprises and just throws projector or hang upside down projector, and because of the difference of projection theory, there is the various projector of various forms and brand, yet, the type of projector does not influence feature of the present utility model, so the utility model does not limit projector's kind or specification.Be that example illustrates technology of the present utility model just to throw projector below.
At first, as shown in Figure 1, projection arrangement with human eye defencive function comprises: a projector body 10, has a projection lens 12, and be provided with the circuit arrangement (not shown) that comprises central processing unit etc. in projector body 10 inside, described projector body 10 can be projected to projection information on the display screen 14; Other has an image-pickup assembly 16, can use Charged Coupled Device (CCD) or complementary metal oxide semiconductor (CMOS) sensing component, image-pickup assembly 16 is arranged on the outside surface of described projector body 10, this image-pickup assembly 16 is exactly to see through human face detection earlier to obtain a user's 18 position, and then captures described user's 18 humanoid image; The humanoid image that captures is sent to image process unit (not shown) in the CPU (central processing unit), after image process unit receives humanoid image, the back produces a humanoid black mask 20 as calculated, export described humanoid black mask 20 is projeced into display screen 14 through projector body 10 opposite position as shown in Figure 2, and according to this user's 18 position.
Wherein, above-mentioned employed human face detection technology is specially and finds out a reference point earlier, then cooperates a motion-vector to detect this user's existence again.Certainly, in the pick-up image process, if insufficient light, more can set up a light filling light source, infrared light sources for example is to provide image-pickup assembly required enough light sources; And this light filling light source can be arranged on the projector body or other any position.
As shown in Figure 1 and Figure 2; because the utility model is to export humanoid black mask 20 on display screen 14 at user 18 position is corresponding; therefore when user 18 faces the projection lens 12 of projector body 10; its high light of launching can be accompanied by humanoid black mask 20; so high light can't shine directly into user 18 eyes; therefore can effectively protect user's eyes; avoid the high light direct projection and damage, more can offer comfortable not dazzling bulletin environment of user.
Above-mentioned black mask is to illustrate in detail as preferred embodiment with humanoid black mask, but is not limited to humanoid black mask, other shape also can, so long as can protect any black mask of user's eyes can.Moreover, the image process unit of above-mentioned processing black mask is built in the projector body inside in can be directly, also can be arranged in external electronic, in order to processing and generation black mask, and this outside electronic installation can be personal computer, mobile computer or PDA(Personal Digital Assistant) etc.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
