Description
Technical field
Taken pictures distortion simulator and its application method the present invention relates to a kind of propeller, belong to experiment equipment and simulation skill
Art field.
Background technology
In daily life, many people have a doubt, take what is come why when the propeller of shooting rotation
Propeller is lopsided in photo, and to shoot lopsided shape in same propeller photo different for different cameras, mobile phone,
And the propeller of the different rotating speed of same lens shooting can also obtain different photo.Most people is doubted in face of such
It is puzzled, all want to go to probe into and understand, especially student, but in the data inquired all it is the formula and technical term of big section, manage
Solution is got up highly difficult, and a lot of people selection is abandoned continuing to look into the causes；Not for the dress of such principle demonstration in prior art
Put, therefore, it is necessary to a kind of new experiment equipment or science stage property aid in understanding.
The content of the invention
In order to overcome drawbacks described above, taken pictures distortion simulator the invention provides a kind of propeller, for analogue camera
Take pictures and propeller rotational, and it is different according to speed, different distortion results is shown, rational in infrastructure, principle demonstration is blunt clear
It is clear.
In order to overcome drawbacks described above, a kind of application method for distortion simulator of being taken pictures present invention also offers propeller.
To achieve these goals, the technical scheme is that：A kind of propeller is taken pictures distortion simulator, including spiral shell
Revolve oar, an in addition to base, the base is provided with a rectangular recess, bottom portion of groove provided with one can pull pumping board, it is described to take out
The long hole slot vertical with pull direction is provided with the middle part of plate, the propeller is set up on groove and blade bottom is close on pumping board
Surface, long hole slot moving region covering propeller orthographic projection region, each propeller blade bottom outer-edge is connected with soft cloth, described
Long hole slot is located on pull direction.
Preferably, base one side or two sides of the groove on pumping board activity direction.
A kind of propeller is taken pictures the application method of distortion simulator, is comprised the following steps：
Step 1）, toward place mat a piece of paper below pumping board and be allowed to fixed, the paper be located at propeller underface and covering propeller just
View field；
Step 2）, toward infiltrating water soluble dyestuffs on soft cloth；
Step 3）, set pumping board on long hole slot be located at propeller orthographic projection region inside edge or more inner position；
Step 4）, uniform rotation propeller and at the uniform velocity outside pull pumping board, the soft cloth below propeller can sweep when passing through long hole slot
Enter in long hole slot and left a trace on paper；
Step 5）, long hole slot stops operating when arriving at the overseas lateral edges in propeller forward projection region or more outward position and propeller and takes out
Draw pumping board；
Step 6）, take out paper, the dyestuff vestige on paper is that propeller is taken pictures distortion shape.
Preferably, the paper is blank sheet of paper, and water soluble dyestuffs are ink.
What common digital camera used is all cmos sensor, and this sensor pulls down fast using electronics roller shutter
Door.Electronics roller shutter drop-down shutter utilizes control system of switching on or off electricity sensor, makes its different piece in the susceptibility of different time interior focusing
Difference, exposed line by line so as to realize, the pixel on cable release is recorded and stored.With the motion of cable release, all pixels are all
It is recorded and stored.Because being to expose line by line, have after first having, when shooting swiftly passing object with digital camera, photo will
It can be distorted.The apparatus and method of the application perfect can be reduced under demonstration different situations by simulating designed by the principle
Propeller take pictures distortion caused by principle, assist in people design reduce distortion conventional method, user can be instructed to close
Reason sets aperture size and shutter speed, improves the image quality that digital camera shoots quick object.
Sci-tech exhibit can be designed to simultaneously, to distortion principle of the public display properller in digital photograph；It is logical
The personal operating experience of the public is crossed, deepens the understanding at the uniform velocity moved to helical form rotary motion and shutter, understands properller
The reason for being distorted in electronic photo.It is favorably improved people's scientific interest.
The beneficial effects of the invention are as follows：It is rational in infrastructure, it is easy to make and popularizes, principle demonstration is clearly understood；The application's
Application method is simple, and different age group can be used fast per capita, and can be interactive, teaches through lively activities.
