The historical film is the short name of the film, has existed for more than a century.
The film works because of the persistence of the vision, in fact, the human eye retains the image of about one person
Two seconds after watching.
At the beginning of the 19 th century, some devices began to appear, using the persistence of vision to create the illusion of motion from still images.
Zoetrope, invented by William George Horner in 1834, consists of a series of pictures placed on a note inside a rotating drum.
There are small cracks in the drum, you can look at the picture through it.
In the case of a special zoetrope called praxinoscope, there is a mirror drum in the middle so you can see the picture by looking at the top of the device.
The picture on the drum changes slightly from one to the next.
By rotating the drum, you can make the picture move fast enough to make your eyes think it's looking at a moving picture.
These pictures are usually repeated actions, such as walking or dancing, because the action is easily circled.
In a circular image bar, the last picture in the series almost matches the first picture, so that the image can create a period of simulated motion, which can be repeated indefinitely, to create the illusion of continuous movement.
The earliest movie projector, such as the lamp, actually appeared in the 1600 s, but they only showed still images.
Some projectors that first showed the moving image simply modified zoetropes.
Creative Entrepreneurs use translucent stripes on drums and place light sources, usually lanterns, in the middle of the box.
They then project the image to a blank wall or a stretch white cloth through a small hole or aperture.
Obviously, these devices are very limited.
They are hand-operated and use the same type of circular animation or photo as the original zoetrope.
With the range of motion that Thomas Edison invented in 1891, everything changed.
Kintoscope uses the motor to rotate a film in front of the light source.
The light source projects the image on the film onto the screen of the booth.
It is clear that people are willing to pay for this type of entertainment, and many inventors are beginning to design variations of Edison's original equipment.
The hand operated kinora was invented by the Lumiere brothers and was a great success in the 1930 s.
The Lumiere brothers, Louis and Auguste, created amazing films in 1895.
This portable device is a camera, a film processing lab, and a projector!
The two brothers made movies in the French countryside for up to a few minutes.
They then processed and screened the film on the spot!
In the second year, vitasope (
This is another variant of kintoscope)
The arrival of a new era of entertainment.
Vitasoft works like a basic range of motion, with a basic difference: the image is projected onto the large screen of the room, not on the small screen on the booth.
Therefore, it started the development of the first theater, namely Nickelodeon in Pittsburgh, PA.
Throughout the 20 th century, movies and projectors have become more and more complex.
The engineers equipped the projector with a sprocket and a wire shaft to quickly move the film in front of the light source.
The length of the movie goes from a few minutes to an hour or more, to the end of 1920, the movie-
The audience is enjoying the "talk" movie, including the soundtrack.
The first color film appeared in the 1930 s, and several new craft and screen format developments appeared in the 1940 s and 1950 s.
The platter made its debut in the 1960 s, completely changing the industry as a whole.
In the 1970 s and 1980 s, automation began to dominate, and in the 1990 s witnessed the emergence of digital sound and the development of LCD technology.
Nevertheless, while modern projectors are brighter, faster and more functional than their predecessors, and manufacturers have added many fancy features over the years, the essence of projectors has remained the same since the beginning of the 20 th century.
Although digital projectors are now popping up in some theaters, the film --
The drama industry is still dominated by simulation.
This is only a matter of practical consideration.
Most theaters have spare parts and local technicians who can easily serve analog projectors.
On the other hand, repairing a digital projector often requires specialized technicians in addition to purchasing replacement parts.
Digital projectors make images using LCD instead of film.
It sounds great at first-
No more scratches or spots!
But the LCD projector has one major drawback: If the LCD has one or two bad pixels (
This often happens)
, This flaw will appear in every movie displayed on the projector.
With the movie, you will lose all the picture flaws once you change the scratch movie or go to another movie.
