CN1424702A - Tunnel inside dynamic image generating method - Google Patents

Abstract

A dynamic image generating method on the wall in the tunnel features that a series of pictures whose contents are continuous are fixed to the wall in tunnel of subway, and when a train passes through them at high speed, the dynamic images can be watched by passenger due to the visual transition principle.

Description

Tunnel inwall dynamic image method of formation

Technical field

The present invention relates to the generation method of dynamic image on a kind of tunnel inwall, especially the dynamic image generation method on the subway tunnel inwall.

Background technology

The ultimate principle of film is the persistence of vision phenomenon.The film that the Chinese film art has been introduced the persistence of vision phenomenon and produced based on this principle in " film everyday expressions note " (Li Suyuan work, Higher Education Publishing House published book number 10010.03 in 1985) from book.The people is when seeing thing, and after looking object had disappeared, its video can persist a moment on people's retina, and this is " persistence of vision " phenomenon.Such as, watch facing to dazzling electric light night, close eyes then immediately, will feel to also have a sparklet in the eyes.When we see thing,, seem that so they will overlap if two image times that successively replace are no more than 1/10 second.This kind phenomenon is often run in the daily life, and when raining, what see is not to drip raindrop but countless very light rain.Film becomes movable video by motionless rest image, also is according to this principle.The image that a width of cloth width of cloth links up is taken in the objective world that video camera will constantly change with given pace (normally 24 frames of per second), it is shown out in screen by the projector of same rotating speed again.Because persistence of vision, spectators are linked up the static image of conversion rapidly, become movable video, film also just by motionless become moving, " work " get up.

Summary of the invention

The objective of the invention is for the passengers that take subway provide a kind of is visual dynamic image by the train vehicle window.

To achieve these goals, the present invention uses the reverse thinking principle, has adopted the method opposite with motion picture projection to generate dynamic image.The process of motion picture projection is that spectators are sitting on the seat regularly, and the image that film projects high-speed motion on screen is spectators' high-speed motions and the present invention generates the method for dynamic image, and picture then maintains static.Be the passenger in the train that travels, and the picture that a series of contents link up is fixed on the tunnel inwall, what the passenger saw in train like this is exactly dynamic image.

The present invention provides a kind of dynamic image for the subway passenger, and a kind of new-type multidate information dissemination method also is provided simultaneously.

Embodiment

Adopt method of the present invention, the fixed form of picture in the tunnel can adopt and directly be fixed on picture on the tunnel inwall or take to make the fixing method of lamp box, but is not limited to the said fixing mode.

Claims (2)

1. the method for formation of dynamic image on the tunnel inwall is characterized in that, is fixed with the picture that a series of image contents have continuity on the unit length of tunnel inwall along continuous straight runs.

2. the method for formation of dynamic image on the tunnel according to claim 1 inwall, it is characterized in that the transversely arranged density of picture should guarantee, when train passes through these pictures with a certain speed, under the effect of persistence of vision principle, can form image that link up, dynamic.
