Abstract
The present invention provides a dynamic display method for a clear and stable static image. The narrow slot imaging principle is used. By limiting and distributing the image picture display angle range by a diaphragm set, the condition that a looker who moves along the distribution direction of a display device in a fixed movement route displays continuously variable frame images is realized, and thereby, the cartoon display effect is obtained. The method is especially suitable for clearly seeing a cartoon advertising film displayed on the wall of a subway tunnel by persons who move on a subway train at high speed.
Description
Technical field
The present invention relates to the dynamic display method of a kind of display packing of dynamic advertising, particularly a kind of still frame, this method is particularly suitable for making the people moving at a relatively high speed on the subway train clearly to see the animated advertising sheet that presents on the subway tunnel wall.
Background technology
Based on the narrow slit image-forming principle, a kind of method that shows animated image under the situation of relative motion between spectators and the device that Englishman in 1989 proposes, this method have been done in the application that improves and put into the subway environment (Chinese patent application 00815682.4[shows the device of many picture groups elephant to the spectators of motion]) by the American in 1999.The flesh and blood of this method is with each frame picture horizontal compression and being positioned in the rectangular box by a certain percentage, on the pairing tank wall of picture center, open a transparent narrow slit, the people can experience the vision reflection of the former squeezed of horizontal amplification before seam when certain distance moves with certain speed perpendicular to the narrow slit direction, because original picture is through horizontal compression, the amplification that produces through this process can make original picture obtain to a certain degree reduction; With the side of a plurality of such casing series arrangement in spectators' intended line of travel, when spectators pass through in their fronts with certain speed, the vision that spectators will experience each casing one by one and be presented is videoed, when the content of each reflection all is to arrange in order and when changing a little than previous picture, just make spectators experience the same dynamic menu effect of similar film.This scheme does not need other ray machine electric installations outside the light source, compares complicacy and cost that greatly reduces device and the viewing effect that can acquire a certain degree with other known schemes.Analyze this simple its actual effect of application scheme and certainly exist following defective: in order to alleviate flickering the narrow slit image-forming principle, this scheme increases as far as possible and appears at human eye simultaneously and watch narrow slit bar number in the scope, concrete measure is just simple to adopt relatively large slit width and the lateral dimension that dwindles each casing, and each casing closely is arranged in together.Do the problem of bringing like this and be not only to have increased and make the more difficulty of high compression ratio frame picture, can not solve bright duty ratio of time simultaneously needs slit width to want narrow contradiction with guaranteeing normally representing of image detail.Because the existence of this contradiction, this scheme can not realize that the high-quality of image detail represents.The another one defective that this scheme exists is that the condensed frame image content in each independent casing all is an independently frame picture, and adjacent light source places, and the content of frame picture is slightly different after the aperture plate.Therefore many narrow slits appear in human eye is watched scope simultaneously, and every interior content of narrow slit all is to belong to the frame picture that content has nothing in common with each other, human eye will be seen the partial content of a plurality of different frame pictures simultaneously like this, can make the people that the sensation of picture entanglement is arranged, the sense of continuity of picture is poor, has a strong impact on the viewing quality of people to dynamic menu.
Summary of the invention
The present invention is for the high-quality that can not realize image detail that solves the said apparatus existence represents the technical matters that causes the entanglement of sensation picture with the partial content of seeing a plurality of different frame pictures simultaneously, and the dynamic display method of clear, the stable still frame of a kind of picture is provided.
Display packing of the present invention comprises following composition:
Taken transverse in the whole frame picture that shows from an expection, continuous is a plurality of contour, wide cell compression picture is laterally single-row in order in squeezed group of plane formation, respectively extend one-level aperture plate and the secondary aperture plate between one-level aperture plate and squeezed group in squeezed group front side are set in 0.5 times the length range in corresponding squeezed group and both sides thereof, the number of the one-level narrow slit diaphragm of one-level aperture plate and the set parallel equidistant of secondary aperture plate and secondary narrow slit diaphragm equates with the cell compression picture number of pairing squeezed group, distance between the narrow slit diaphragm in the same aperture plate is less than the cell compression picture width of pairing squeezed group, one-level, one-level on the secondary aperture plate, diaphragm group of the corresponding one by one composition of secondary narrow slit diaphragm, each diaphragm group is all corresponding with a cell compression picture, by described squeezed group and corresponding one-level aperture plate, secondary aperture plate and light source constitute the single frames picture display unit, by described a plurality of single frames picture display unit successively along the transversely arranged dynamic display device that constitutes continuous still frame of direction of motion.
Display packing of the present invention can also be taked following technical measures:
Described squeezed group is made of 3 to 150 cell compression pictures.
One-level narrow slit diaphragm slit wide on the described one-level aperture plate is 0.6～5 millimeter, and length equals the cell compression height at least.
Secondary narrow slit diaphragm on the described secondary aperture plate, its width greater than one-level narrow slit diaphragm less than the cell compression picture width.
Described one-level, its longitudinal axis of secondary aperture plate overlap with squeezed group longitudinal axis at squeezed group plane inner projection.

Embodiment
Provided by the invention on route with predictable speed motion beholder show dynamic menu device embodiment as shown in Figure 1, by 50 single frames picture display unit 1 contour one by one laterally and beholder's direction of motion 2 be parallel to beholder's moving line side, each single frames picture display unit is by also may comprehensive multiple factor freely choosing that actual application environment determines to distance (being the distance D m of beholder to the single frame picture unit) most cases of beholder's moving line, is provided with between per two adjacent single frames picture display unit at interval or does not establish at interval.
Single frames picture display unit shown in Fig. 2,3,5, the horizontal single-row laying squeezed group in backboard 4 surfaces, it is contour, wide and by the series arrangement of action gradual change to constitute the cell compression picture 5 of squeezed group, the backboard front side is provided with the one-level aperture plate 9 that is parallel to backboard, distance D b between them is determining the geometric thickness of device of the present invention, in most cases is subject to actual application environment.The factor of another one restriction Db is the processing technology of squeezed.There is a minimal value D ε in the diameter of forming the minimum pixel point of this picture, again because human eye to the resolution angle θ m of motion scenery be about 7.5 ', when D ε/Db＞sin θ m, the resolution (resolution) of the picture that the beholder experienced on beholder's direction of motion can not satisfy human eye and can reach best result and distinguish power, can not obtain the expressive ability of best image detail, so under the situation that actual application environment allows, the distance D b between one-level aperture plate and the squeezed group should be not less than the value of D ε/sin θ m.Cross directional stretch rate when Dm/Db can obtain the cell compression picture and is presented in the human eye, in order to obtain best reduction effect, the horizontal compression of cell compression picture is than also being defined as Db/Dm thus.
One-level aperture plate 9 is provided with the one-level narrow slit diaphragm of parallel equidistant, the number of each one-level narrow slit diaphragm and highly equal cell compression picture 5 number and the height.About the slit width of one-level narrow slit diaphragm, if the wide expressive ability that can influence image detail of narrow slit will cause diffraction of light and narrow slit is narrow.Just can not have influence on the viewing effect of human eye in theory greater than the formed diffraction effect of narrow slit of 800 times of wavelength of light, the wavelength of visible light scope is between 380 ~ 750 nanometers, so slit width should be greater than 0.6 millimeter.Again because the human eye resolution angle is about θ s=1.5 ', be that human eye is unresolvable simultaneously, so the width of narrow slit is nonsensical to the resolving power that improves image detail less than (Dm-Db) sin θ s less than the image detail in this subtended angle.In addition because human eye to the resolution angle θ m of motion scenery be about 7.5 ', so the width of narrow slit less than Db*sin θ m for improving the resolution also not too big help of people to the picture experienced.Comprehensive above three factors guarantee the big bright duty ratio of time of trying one's best simultaneously in order to obtain the highest screen resolution, and the seam of narrow slit is wide should choose maximum one between 0.6 millimeter, (Dm-Db) sin θ s and these three length values of Db*sin θ m.Under the certain situation, in order to obtain higher bright duty ratio of time or to be in the restriction of processing technology cost, also can adopt bigger slit width, but had better not be greater than (Dm-Db) sin θ m, the so obviously resolution of reduction picture, so narrow slit breadth extreme is 5 millimeters and is advisable.
The one-level narrow slit diaphragm spacing Wb of one-level aperture plate can be determined to three parameters of width W i of squeezed group distance D b and cell compression picture to distance D m, the one-level aperture plate of single frame picture unit by the beholder: Wb=Wi (Dm-Db)/Dm.Another improves bright duty ratio of time method is at the spacing Wb that reduces one-level narrow slit diaphragm under the prerequisite of the horizontal compression ratio of above-mentioned all conditions and too high cell compression picture as far as possible, can increase the beholder like this and effectively watch the one-level narrow slit diaphragm bar number of seeing simultaneously in the scope, thereby improve bright duty ratio of time.
The complete required move distance So of all single frames picture optical informations of single frames picture display unit that receives when the width W i of cell compression picture has determined in fact indirectly that spectators are parallel to device motion of the present invention on distance squeezed group is the distance of Db, its formula is: So=Wi (Dm-Db)/Db, the product of the cell compression picture number N in each single frames picture display unit and the width W i of cell compression picture has determined the width W n of single frame picture unit.The ratio of beholder's speed and Wn is the switching frequency (being frame rate) of single frames picture in the dynamic menu, and this frequency can not will reach the animation effect that fine sense of continuity is arranged and require this frequency greater than 20 hertz usually less than 10 hertz.For prevent to have simultaneously belong to respectively two image contents more than the frame picture be presented to the beholder the eye in consideration, generally the value of Wn/So to be controlled at more than 1/2, can make Wn/So=1/2 (as shown in Figure 7) in order effectively to improve bright duty ratio of time.
Its longitudinal axis of one-level aperture plate overlaps with squeezed group longitudinal axis at squeezed group plane inner projection among Fig. 2.Be provided with secondary aperture plate 8 between one-level aperture plate 9 and the squeezed group, this secondary aperture plate is provided with and each one-level narrow slit diaphragm of one-level aperture plate secondary narrow slit diaphragm one to one, and the height of secondary narrow slit diaphragm equates that with one-level narrow slit diaphragm width is 5 millimeters.Support 6 peripheries of single frames picture display module are provided with light shield 10, and backboard 4, one-level aperture plate 9 and light source 7 all are supported in support, and light source 7 is located between cell compression group of picture and the secondary aperture plate.
Constitute this display device along spectators' direction of motion is transversely arranged successively by 50 single frames picture display modules shown in Figure 1.For ease of safeguarding and changing image content, between each single frames picture display module 0.2 meter interval is set.
According to the narrow slit image-forming principle, each cell compression picture and narrow slit corresponding with it in the single frames picture display unit of the present invention all form a narrow slit imaging arrangement, as shown in Figure 4.All there are simultaneously different separately imaging angular range (people just can see image information in this angular range), its key to be that distance between the one-level narrow slit diaphragm is less than the cell compression picture width of pairing squeezed group.For same single frames picture display unit, the angular range of all narrow slit imaging arrangements that it comprises all and predetermined beholder's moving line in same highway section, just on predetermined beholder's moving line, their imaging scope is (common So is promptly arranged) that overlaps.For the beholder who moves along projected route, the position of the formed vision of each the narrow slit imaging arrangement in same single frames picture display unit reflection is not identical (between adjacent two in the distance of watching the Wi that staggers on the travel direction), and this will ask each the cell compression image content in the same single frame picture unit also all can not be identical.The content of each cell compression picture will be given the position of the formed vision reflection of beholder that moves along projected route according to the narrow slit imaging arrangement at this squeezed place, offers in people's the whole frame picture intercepting and obtains along compression on beholder's moving line direction in this single frames picture display unit expection.
Provided by the invention on route, showing supporting construction such as the support among Fig. 26 that the device of dynamic menu also should have all has functional part to above-mentioned with predictable speed motion beholder, also need where necessary to carry out the side plate that light covers and prevent that the light that light source sent of this device from penetrating from the position beyond the narrow slit diaphragm with extraneous.
Device provided by the present invention is effective, with low cost, and technology is simple, and is low in energy consumption, and the reliability height is fit to multiple applications.Utilize device provided by the present invention and embodiment to compare with known technology in the past, can be under given applied environment more reasonable more implementing of science and make the dynamic menu display capabilities obtain the performance of amplitude peak, can effectively improve the sharpness and the details expressive force that are presented on the dynamic menu in the eye, the frame handoff procedure is natural and tripping, and the dynamic menu sense of continuity is good; And because single frame picture unit modular design of the present invention, global reliability improves, and installation, maintenance and replacing image content are more convenient.
