Description

Dull and stereotyped 3-D digital photo frame

Technical field

The present invention relates to the multimedia field, in particular to a kind of dull and stereotyped 3-D digital photo frame.

Background technology

Digital frame, be also referred to as digital album (digital photo frame), its ultimate principle is the moulding that outward appearance adopts common photo frame, photo in the middle of the original photo frame is partly changed into LCDs, mix power supply, storage medium etc. can be play-overed digital photograph, making in the same photo frame can the loop play photo, more has superiority than the simple function of common photo frame.

Two photos before and after the multipotency of traditional photo frame is placed, the Mr. and Mrs of some new marriages want the photo of oneself is illustrated in the new house more, can place thousand sheets digital photograph and are pursued and occurred digital album (digital photo frame) now.

The digital stereo photography is commonly called as three-dimensional real scene shooting, it is present international most popular stereopsis production method, be that stereotome utilization ordinary digital camera is once taken the different photo of many subtended angles degree, after the synthetic output of the synthetic technology mounting through specialty, just become a lifelike stereoscopic photograph picture.Change the cubic phase ratio with the plane, its feature be the focus object mellow and full abundant, stereoscopic sensation is strong, vivid; With multi-lens optical stereoscopic photograph than mutually, it is low, effective, easy and simple to handle that it has a cost, the yield rate height has reduced making link.Photo studio, advertising company, shutterbugs' GPRS the digital stereo camera work, need not acquire equipment, just can finish the upgrading of camera work with existing digital camera.The introduction of digital stereo camera work for three-dimensional wedding photo, advertising circle provide best technical solution, will cause the technical revolution of photography and advertising sector.

Let us is understood stereographic know-why with human vision.Human eyes similarly are cover digital camera fully automatically, have zoom lens, iris ring and light signal can be transformed into the electric signal that brain can be discerned.In essence, single the just two dimensional image of object that eyes are seen, we can tell its height and width, and can't discern its degree of depth; In two dimensional image, utilize relevant size that object provides and visual cues such as overlapping, we can judge the front and back ordering that is positioned at these objects before the background, but can't know but between them actually distance is how far.

Fortunately we mankind have had two eyes, and all grow face in front, are horizontally, are about 60mm at interval.When we saw same object, because that residing angle has is slightly different, the image that two eyes are seen still had difference slightly, and our brain combines this two width of cloth picture, forms a kind of vision of the degree of depth.The process of this overall treatment is very rapid, and flawless, and the visual experience of generation similarly is that we are seeing thing through an oxeye.

The visual angle is meant the vertical direction angulation of sight line and display etc., when observing object, and the angle that the light that (upper and lower or left and right) drawn from the object two ends becomes in human eye photocentre place.The size of object is more little, and far away more from the observer, then the visual angle is more little.The minimal visual angle that normal eye can be distinguished two points on the object is about 1 fen.

At present, auto-stereoscopic display based on grating has progressively moved towards to use, and size from small to large, but these auto-stereoscopic displays are all based on the integer visual angle, as 4 visual angles, and 6 visual angles, 8 visual angles, 9 visual angles etc., and need some specialized apparatus, drive demonstration stereotome or video as PC.

And at dull and stereotyped 3-D digital photo frame, because the portable characteristics that itself have, self has contained picture display process and video processing function, but the data volume of its processing is less, can't handle the data of various visual angles, and adopt very few visual angle can't obtain stereoeffect preferably, cause user's experience relatively poor.

Summary of the invention

The objective of the invention is to, a kind of dull and stereotyped 3-D digital photo frame is provided, it can realize stereoeffect preferably under the situation that adopts less visual angle grating.

The invention provides a kind of dull and stereotyped 3-D digital photo frame, comprising: display screen, grating, glass plate and shell, wherein

Glass plate is pasted together with the grating that designs according to 4.5 visual angles; Distance between display screen and the grating is d, wherein

$d=\frac{S*\mathrm{<figure-callout\; id="3"\; label="D"\; filenames="HSA00000223593200012.png"\; state="\{\{state\}\}">D</figure-callout>}}{3*W}$

Wherein, W is people's an eyes distance, and D is the viewing distance between people and the dull and stereotyped 3-D digital photo frame, and S is the some distance of display screen; And

Shell is installed together display screen and the grating and the glass plate that are pasted together.

Preferably, in above-mentioned dull and stereotyped 3-D digital photo frame, grating comprises: transparent part and opaque section, wherein

The ratio of transparent part and opaque section is between 1/4 and 1/5.

Preferably, in above-mentioned dull and stereotyped 3-D digital photo frame, but the area of grating is more than or equal to the display area of display screen.

Preferably, in above-mentioned dull and stereotyped 3-D digital photo frame, the area of glass plate is more than or equal to the area of grating.

Preferably, in above-mentioned dull and stereotyped 3-D digital photo frame, grating or right bank becomes inclined angle alpha with display screen, wherein left

$\cos \mathrm{\&alpha;}=\frac{4\mathrm{DS}}{p(D+d)},$

Wherein, p is the pitch of grating, and D is the viewing distance between people and the dull and stereotyped 3-D digital photo frame, and S is the some distance of display screen, and d is the distance between display screen and the grating.

Preferably, in above-mentioned dull and stereotyped 3-D digital photo frame, glass plate and grating adopt no shadow glue to paste.

The foregoing description adopts the grating according to the design of 4.5 visual angles, and the distance of grating and display screen is set to specific for d, the picture at 5 specific visual angles or video are by behind this grating, can make observer's left eye and the picture that right eye is seen adjacent two visual angles respectively, in eyes, obtain parallax, and then pass through people's brain formation stereoeffect, thus under the situation that adopts less visual angle grating, realized stereoeffect preferably, overcome problems of the prior art.
