Embodiment
The invention provides a kind of electronic type light shield device, the transmission-type panel is arranged at before the camera lens, and be full shading or part shaded effect in electronically controlled mode with modulation panel, the light that the user can remote control mode selective masking camera lens be projected is with projection or close projected picture.Below lifting a projector is that example elaborates, however those skilled in the art should understand, present embodiment only be a kind of embodiment of invention of the present invention under spiritual, can't limit the protection domain of wanting of the present invention.
Fig. 1 is the partial perspective view of expression according to the projector of a preferred embodiment of the present invention, and Fig. 2 is the side view of the projector of presentation graphs 1.With reference to Fig. 1 and 2, the projector of present embodiment (projector) 100 comprises: housing 70, ray machine (light engine), light shield device 90 and Transparent Parts (as Figure 28 5) simultaneously.Housing 70 has an opening 72, and ray machine (as Figure 28 0) comprises the projection lens (projection lens) 82 that is arranged at also relative opening 72 in the housing 70.Light shield device 90 has an adjustable shading region, the light that is throwed in order to selective masking projection lens 82.
Fig. 3 is the calcspar of expression according to the projector of Fig. 1.Light shield device 90 comprises panel (modulation panel) 92, receiver 96 and control module (control unit) 94.
As shown in Figure 2, panel 92 has the pixel of a plurality of arranged, and panel 92 is arranged at before the projection lens 82, and with respect to opening 72.Panel 92 is a transmission-type panel preferably, for example be a display panels (Liquid Crystal Display Panel) or a transmission-type monocrystalline silicon display panels (Liquid Crystal on Silicon, LCOS).
As shown in Figure 3, receiver is in order to received signal, and exports control module 94 in view of the above to.Receiver for example is an infrared receiver (IR receiver) 96, in order to receive a remote signal.Control module (control unit) 94 receives a signal, and sets in view of the above that a little pixels are shading in the shading region of panel 92, wherein forms shading region.
In the present embodiment, the disposal route of projects images comprises step: provide a panel before a camera lens, panel has the pixel of a plurality of arranged; One shading region of selected panel; Set shading region, a plurality of pixels of shading region are set at shading.
With reference to Fig. 3～4, Fig. 4 is the process flow diagram of the image processing method of light shield device in the presentation graphs 3 simultaneously.The projector 100 of present embodiment produces a miniature image by ray machine 80 effects, and projection lens 82 produces a projects images in view of the above.In the step S101 of panel was provided, panel 92 had a plurality of pixels with arranged, and is arranged at before the projection lens 82.In the step S102 of selected shading region, the user selectes shading region 92a by modes such as manual editing or automatic editors, and exports this instruction to receiver 96 by a remote control unit 20.Command content comprises the pixel on pairing horizontal direction in the border of photic zone and the vertical direction.In setting the step S103 of shading region, after control module 94 received signals, and in view of the above the pixel in the shading region of panel 92 is set light tightly, and the remainder of panel 92 is set at a photic zone, and a plurality of pixels of photic zone are set at printing opacity.Handle projects images in view of the above.
The shading region pattern of below lifting several groups of panels is that example is done explanation, and sets forth the treatment effect of the projects images of its generation.Following embodiment only is several groups of embodiments under the invention spirit of the present invention, can't limit the protection domain of wanting of the present invention.
With reference to Fig. 5 A, it is the panel front view of projector when projects images of expression present embodiment.When projection during based on projects images, the panel of part forms shading region 92a, and another panel 92 partly forms photic zone 92b and relatively during projection lens, the light that projection lens projected passes photic zone 92b and forms a projects images on a screen.See through fine-tuning photic zone, the electronic type light shield device can be modified projected picture speck (light leakage) in addition in order to cover projected picture parasitic light (light stray) in addition, improves the display quality of projected picture significantly.
With reference to Fig. 5 B, it is the panel front view of projector when projects images not of expression present embodiment.When projector not during projects images, shading region 92a for example is that photic zone overlaps with projection lens basically with respect to projection lens, the light that shading region 92a covers projection lens fully and projected.At this moment, panel 92 cover fully projection from the light of projection camera lens with as a lens cap.Compare with the Machine Design of conventional lenses lid, the user can be the shading state by the projection state exchange with light shield device by remote control mode only, with real-time switching projected picture.Particularly be set up in the projector of ceiling, the light shield device of present embodiment adopts remote control mode, can solve the inconvenience of removing with the additional mirror skull.Say that further by using the projector of present embodiment, the user can select required bulletin media at any time in the occasion that bulletin or meeting etc. is seized every minute and second, for example be blank, projected picture, placard or the like,, create enterprise competitiveness to simplify the meeting time.
With reference to Fig. 2, the projector 100 of present embodiment also comprises a Transparent Parts (hard coat) 85, is arranged in the opening 72, for example is that the mouth wall of Transparent Parts and opening joins to be embedded in the opening, has protection panel and dustproof effect concurrently.In addition, panel 92 preferably be arranged at Transparent Parts 85 after, and be close to Transparent Parts 85, Transparent Parts 85 is in order to protection panel 92 and projection lens 82.With regard to board in appearance, the Transparent Parts 85 and the panel 92 of present embodiment are embedded in housing, can keep the moulded consistance of projector 100.
Projector with light shield device that the above embodiment of the present invention is disclosed and projects images disposal route thereof are arranged at the transmission-type panel before the camera lens, and modulation panel are gone out the effect of various shadings and printing opacity in electronically controlled mode.At first, panel can electronically controlled mode be modulated to full shaded effect, the user can show or close projected picture by remote control mode, not only save the trouble of manually opening entire lens cap, the various bulletin medium of cross-application are to simplify the meeting time more easily, lifting time service efficiency, help to promote in the enterprise operation and management through the power of striving.Moreover panel can be modulated and produce shadowed layer and local translucent effect, do not needing manually and only under the situation with remote operation, the panel of present embodiment can local printing opacity to throw picture penetrating to allow.Say that further the more fine-tuning photic zone of panel border reaches better projection quality to cover projected picture parasitic light in addition.On the other hand, at board in appearance, Transparent Parts and panel are embedded in housing, not only promote protection and dustproof effect, also can keep the moulded consistance of projector.
In sum; though the present invention discloses as above with a preferred embodiment; yet it is not in order to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; certainly can be used for a variety of modifications and variations, so being as the criterion of should being defined with the book scope of claim of protection scope of the present invention.
