Abstract

The utility model relates to a multifunctional domestic stereo image display device which mainly comprises an image display terminal, a main controller and a pair of active stereo glasses, wherein a control circuit of the main controller comprises a delay circuit and a changeover control switch. The utility model at least comprises one pair of stereo glasses, and a frame of the stereo glasses is provided with a phase control switch. The three-dimensional processing effect of the utility model is simpler, more reliable, more convenient and more ideal than that of other methods (for example, processing of using three-dimensional software and a video card, storing images, calculating, replaying, etc.); the utility model can conveniently control synchronously viewing left and right videos by the left eye and the right eye.

Description

The multi-functional household stereo imaging device

Technical field

The utility model relates to Image Communication, specifically is a kind of in order to view and admire the multi-functional household stereo imaging device of stereo-picture on the video picture terminal.

Background technology

Video picture terminals such as the televisor in modern times or computer monitor all are continuous (frame frame) output pixel of an every trade, Yi Changchang on screen, between row and row, field and field, are all arranged the time interval in a flash.When people's eyes are seen thing, the scenery that images of left and right eyes is seen is not quite similar, be the scenery that the scenery seen of left eye and right eye are seen, be that certain parallax is arranged, a complete scenery is then seen in two combinations, and the material object of seeing because of eyes has front and back " degree of depth ", therefore, visual effect is three-dimensional.When people's eyes were seen image on the video picture terminal, if do not have potential difference between strange, the idol of pixel, the image of then seeing was two dimensional image, otherwise, then can obtain the effect of 3-D view.So in the prior art, for reaching the effect that can watch stereo-picture in the video picture terminal, everyone disposes the secondary anaglyph spectacles except being necessary for the beholder, it also must take special stereo-picture with special method.A kind of " fully compatible flashless time-sharing stereo TV system " (publication number CN1230858A) disclosed as the Chinese patent communique, its image pickup method is, at first should aim at a bit in the scenery, make video camera center on this point then and rotate shooting or right-to-left rotation shooting from left to right, and showing this image with this image recording, emission, transmission and by ordinary television receiver, spectators watch this flicker free three-dimensional television image by the three-dimensional liquid crystal glasses that is subjected to vision signal control.See thus, stereo-television system so, photographing request is higher, the signal Processing complexity, and what generally be used for televisor can not be used for computer, or be used for computer can not be used for televisor, what be used for computer also must be equipped with special-purpose software and driver, to image store, processing such as computing, playback, and the video card of configuration had higher requirement, therefore, circuit complexity not only, the price height, and also also relatively harsher to the requirement of using.

Summary of the invention

The purpose of this utility model provides a kind of multi-functional household stereo imaging device that can make two dimensional image convert 3-D view automatically to, and makes it directly to use with general television set or computer, and does not need televisor or computer are done any change.

Realize the utility model of above-mentioned purpose, consist predominantly of a video picture terminal, a master controller and an active anaglyph spectacles.Video picture terminal in the utility model can be a general television set, also can be computer.Master controller in the utility model links to each other with the video picture terminal, promptly when the utility model links to each other with general television set, master controller is connected on the video terminal of televisor (or video disc player); When the utility model links to each other with computer, master controller is serially connected in the VAG interface (D type plug) of host computer and display.Characteristics of the present utility model are in the operation circuit of master controller, include a delay circuit and and switch gauge tap.The same with existing anaglyph spectacles, the left and right sides eyeglass of the utility model neutral body glasses is the liquid crystal glasses sheet for having the light valve function also, the appropriate position is provided with an infrared receiving window mouth on the mirror holder, in the utility model, at least include a secondary anaglyph spectacles, and be that the mirror holder of this anaglyph spectacles is provided with a phase control switch.

The utility model as mentioned above, pixel in the video picture terminal line by line/interlacing show switching control function promptly by in the master controller line by line/interlacing switching controls switch realizes, and two dimensional image is converted to the 3-D view function automatically, then can control by delay circuit and switching controls switch, cause strange/even field picture alternately video picture continuously with horizontal shift, when watching with anaglyph spectacles, will make the two dimensional image of computer become the stereo-picture vision with three-dimensional depth of field sense, the stereoscopic sensation to real border image and three-dimensional design image is more obvious especially.

The utility model has the advantages that, switch gauge tap owing to be provided with a delay circuit and in the master controller of the utility model, the video picture terminal is demonstrated have the strange/even field picture of horizontal shift, when replacing video picture continuously, when watching with anaglyph spectacles, the stereo-picture vision that two dimensional image is become have three-dimensional depth of field sense.See thus, this disposal route of making 3-D view with delay circuit and switching controls switch, need not pass through the image stores processor, need not any 3D software, needn't allow computer participate in the calculation process of display image is operated, thereby do not have the storage of image rgb signal and read distortion and the time difference, also needn't specific (special) requirements be arranged to host computer and video card.Because the quality of image depends primarily on rgb signal, the initial field signal that depends on that image shows, the position that image shows is just relevant with line frequency, therefore, postpone to handle through line frequency every the field, quality to image does not have distortion, and just can realize control in the VGA of computer and display connecting line, so the 3D processing effect is simpler, reliable, convenient, desirable than other method (as using three-dimensional software and video card, image storage playback etc.).An a control left side/right video and a left side in the utility model/synchronous measure of right eye eyeball acquisition is a phase control switch that is provided with on the mirror holder of anaglyph spectacles, press by this switch, can make the light valve effect of the left side/right liquid crystal lens of anaglyph spectacles switch corresponding with a left side/right video, this feature makes that use is quite convenient, particularly better under family's theater type (many people) viewed status.

Use for adapting to various states, the utility model can be equipped with wired output interface on master controller, and correspondingly the appropriate position is provided with a wired connection socket on the anaglyph spectacles mirror holder.
