Abstract

The utility model provides a stereoscopic slide show, which can be showed by common slide projectors. The slide frames are provided with parallax patterns made up of different colors. Two parallax patterns have a certain displacement in the horizontal direction, matching with a color filter with different colors in the two eyes simultaneously. When a viewer watches the slides through the color filter, because of the subtractive color function or the color synthetic function of the color filter, the two eyes can see different patterns with parallax, thus the stereo effect is produced. The stereoscopic slide show provides convenience for the work of teaching, scholarly communication, etc., and to a certain extent, can replace the real objects or the stereo models. In addition, the utility model can increase the teaching vitality by utilizing the superposition effect of the multi-layer picture.

Description

Stereoscopic slide show

The utility model relates to a kind of stereopticon, particularly a kind of parallax pattern of making different color on lantern slide, and the stereopticon or the stereoprojection of adapted different color goggles with color filter.

The application of magic lantern (comprising projector) is increasingly extensive in modern teaching and academic exchange activity, and the various improvement projects of magic lantern also constantly occur.But there is not a kind of magic lantern that can show stereoscopic picture plane all the time.

Task of the present utility model provides a kind of stereopticon, and it by color Superposition Method or subtractive color process, and produces stereoeffect according to two of the mankind's principle of parallax, shows stereoscopic image.It can show the superposition effect or the stealthy effect of multilayer picture by the needs of teaching or academic report simultaneously.

The present techniques scheme is as follows: on the picture of lantern slide or projector film, make two by the binocular parallax principle parallax pattern certain displacement, different color is arranged in the horizontal direction, be two different goggles with color filter of beholder's adapted simultaneously, two eyeglasses of the goggles with color filter color with two parallax patterns respectively are identical or close.For example the parallax pattern is made of red, green two kinds of colors respectively, green pattern is identical with red pattern, and displacement to the right (for example 0.8mm), then two of color filter are respectively red, green dichromatism (color of left and right color filter is done opposite configuration according to picture of the bright end and picture of the dark end different).The mirror holder of color filter all can be identical with existing glasses with eyeglass, and eyeglass can adopt coloured glass, colored plastic, organic glass or other colorful films to constitute.When practical, spectators' eyes are watched picture by different color filter, show or certain color of elimination through the Superposition Method of color, make eyes see different (parallax is arranged) picture respectively, and produce stereoeffect.Can some pattern be the color mixture of two parallax patterns or the color mixture that contains these two kinds of colors and other color simultaneously in the lantern slide picture, this part pattern can be eyes and sees that simultaneously background patterns also can be only identical with a view case color, at this moment have only eyes can see background patterns, but subjective effect is identical.

The design has solved the problem of diaprojection stereoscopic image with very easy method, for teaching and academic exchange provide convenience, can replace material object or model to a certain extent.Simultaneously, also, provide effective tool for needing the occasion of multilayer picture superposition in the teaching.

Now be described further with embodiment in conjunction with the accompanying drawings.

Fig. 1 is that the parallax pattern of different color constitutes synoptic diagram;

Fig. 2 is the goggles with color filter structural representation;

But Fig. 3 is the superposition picture constitutes synoptic diagram.

With reference to Fig. 1, embodiment 1, lantern slide of the bright end: a selected earlier level (accords with human eye, when you note observing jobbie, though the background object before and after it can find out it all is empty as main scape.The depth of field reason of this and camera is the same) profile of object to be painted respectively put thereon, the color of these profiles is to approach orange and approach red (solid line part ［ 1 ］ expression).The profile of second amplitude object is to be plotted on the same background by approaching the color that Lan Lvhe approaches blue look, and second width of cloth profile and the horizontal direction of first width of cloth profile on background have individual displacement, as shown in Figure 1, and dotted portion ［ 2 ］ expression.The 3rd class background lines ［ 3 ］ should be the superposition look of first and second class lines and draw.

Embodiment 2, lantern slide of the dark end:

The selected method of background is identical with lantern slide of the bright end.First width of cloth profile diagram is used and is approached green orchid and approach green color drafting, as shown in Figure 1, and solid line part ［ 1 ］.Second width of cloth profile usefulness approaches orange red and approaches red color and draw, as shown in Figure 1, and dotted portion ［ 2 ］.The 3rd class lines not any look (lines of promptly having powerful connections are the water white transparency lines) background color should be the superposition look ［ 3 ］ of first and second class lines look, lantern slide of so dark end has just been manufactured success.

The method for making of anaglyph spectacles, with reference to Fig. 2: one pair of anaglyph spectacles, its contour structures and common spectacles do not have big difference.It is characterized by: the color of two eyeglasses has nothing in common with each other, and one is to approach red ［ 4 ］, and another approaches ［ 5 ］ of blue look.Two examples that this explanation is passed the imperial examinations at the provincial level (lantern slide at the bright end, the dark end) all should use a left side red right blue (for observer) as shown in Figure 2.The color configuration of lens depends on the color configuration on the lantern slide.The material of eyeglass can be all material transparent as glass, organic glass, plastic sheet etc.Watch anaglyphic lantern slide can obtain the body of 3 D stereo by these glasses.

Utilize same principle, can realize the superposition of multilayer lantern slide, embodiment 3, as shown in Figure 3, a right cylinder ［ 6 ］ by bevel one cutter after, middle face is ellipticity, we paint a kind of color to the elliptic contour of the first half ［ 7 ］, the elliptic contour of the latter half ［ 9 ］ is painted another kind of color, and remainder is painted the color mixture of these two kinds of colors.When ［ 7 ］ sheet and ［ 8 ］ sheet were pieced together ［ 6 ］ sheet, middle section line just can conceal fully like this.And when ［ 7 ］ when sheet is removed, section line can reappear again, thereby realizes the superposition of multilayer lantern slide.The elliptic wheel profile of above-mentioned upper and lower part, color also of the same race but its colourity difference.That the colourity of all the other colors should be these two colourities and colourity (colourity is the intensity of color).

Above Fa Ming application:

1, slide instruction and transparency.

2, make the stereotelevision sheet.

3, make the three-dimensional film sheet.

4, draw the color solid atlas.

5, take stereoscopic photograph.

6, make three-dimensional postcard, playing cards etc.

Claims

1, a kind of stereopticon, by common slide projector or projector projection, on lantern slide, be provided with the parallax pattern of making by different colours, two parallax patterns have certain displacement in the horizontal direction, it is characterized in that being furnished with goggles with color filter, the two colour of lens color with the parallax pattern respectively are identical or close.
