Kinematoscope
The Kinematoscope (a.k.a. Motoscope) was patented in 1861 (United States Patent 31357), a protean development in the history of cinema. The invention aimed to present the illusion of motion. The patent was filed by Coleman Sellers of Philadelphia, Pennsylvania as an "improvement in exhibiting stereoscopic Stereoscopy (also called stereoscopics, or stereo imaging) is a technique for creating or enhancing the depth perception, illusion of depth in an image by means of stereopsis for binocular vision. The word ''stereoscopy'' derives . Any stere ... pictures". Coleman applied stereoscopy to the existing principle of toy phantasmascopes using rotating discs. A series of still stereographic images with successive stages of action were mounted on blades of a spinning paddle and viewed through slits. The slits passed under a stereoscopic viewer. The pictures were visible within a cabinet, and were not projected onto a screen. References Audiovisual introductions in 1861 H ...

Coleman Sellers II
Coleman Sellers II (January 28, 1827 – December 28, 1907) was a prominent American engineer, chief engineer of William Sellers & Co., professor of mechanics at the Franklin Institute, professor of engineering practice at Stevens Institute of Technology and inventor. He obtained more than thirty letters-patent for inventions of his own, and served as president of the American Society of Mechanical Engineers from 1886 to 1887. Biography Early life Sellers was born in Upper Darby, Pennsylvania as the youngest son of Coleman and Sophonisba (Peale) Sellers and a direct descendant of Samuel Sellers, who in 1682 received one of the first grants of land in Pennsylvania. His father and a number of paternal ancestors had been engineers; his maternal grandfather was Charles Willson Peale. He was educated at common schools and studied for five years with Anthony Bolmar at his academy in West Chester, Pennsylvania. Early career In 1846, Sellers became draughtsman in the Globe Rolling Mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

History Of Cinema
The history of film chronicles the development of a visual art form created using film technologies that began in the late 19th century. The advent of film as an artistic medium is not clearly defined. However, the commercial, public screening of ten of the Lumière brothers' short films in Paris on 28 December 1895 can be regarded as the breakthrough of projected cinematographic motion pictures. There had been earlier cinematographic results and screenings by others like the Skladanowsky brothers, who used their self-made Bioscop to display the first moving picture show to a paying audience on 1 November 1895 in Berlin, but they lacked neither the quality, financial backing, stamina, or the luck to find the momentum that propelled the cinématographe Lumière into worldwide success. Those earliest films were in black and white, under a minute long, without recorded sound and consisted of a single shot from a steady camera. The first decade of motion pictures saw film mov ...

Motion (physics)
In physics, motion is the phenomenon in which an object changes its position with respect to time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed and frame of reference to an observer and measuring the change in position of the body relative to that frame with change in time. The branch of physics describing the motion of objects without reference to its cause is called kinematics, while the branch studying forces and their effect on motion is called dynamics. If an object is not changing relative to a given frame of reference, the object is said to be ''at rest'', ''motionless'', ''immobile'', '' stationary'', or to have a constant or time-invariant position with reference to its surroundings. Modern physics holds that, as there is no absolute frame of reference, Newton's concept of '' absolute motion'' cannot be determined. As such, everything in the universe can be considered to be in motion. Motion applies to various p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philadelphia, Pennsylvania
Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of world's largest metropolitan regions, with 6.245 million residents . The city's population at the 2020 census was 1,603,797, and over 56 million people live within of Philadelphia. Philadelphia was founded in 1682 by William Penn, an English Quaker. The city served as capital of the Pennsylvania Colony during the British colonial era and went on to play a historic and vital role as the central meeting place for the nation's founding fathers whose plans and actions in Philadelphia ultimately inspired the American Revolution and the nation's inde ...

Stereoscopy
Stereoscopy (also called stereoscopics, or stereo imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word ''stereoscopy'' derives . Any stereoscopic image is called a stereogram. Originally, stereogram referred to a pair of stereo images which could be viewed using a stereoscope. Most stereoscopic methods present a pair of two-dimensional images to the viewer. The left image is presented to the left eye and the right image is presented to the right eye. When viewed, the human brain perceives the images as a single 3D view, giving the viewer the perception of 3D depth. However, the 3D effect lacks proper focal depth, which gives rise to the Vergence-Accommodation Conflict. Stereoscopy is distinguished from other types of 3D displays that display an image in three full dimensions, allowing the observer to increase information about the 3-dimensional objects being displayed by head and eye mov ...

Phantasmascope
The phenakistiscope (also known by the spellings phénakisticope or phenakistoscope) was the first widespread animation device that created a fluent illusion of motion. Dubbed and ('stroboscopic discs') by its inventors, it has been known under many other names until the French product name became common (with alternative spellings). The phenakistiscope is regarded as one of the first forms of moving media entertainment that paved the way for the future motion picture and film industry. Like a GIF animation, it can only show a short continuous loop. Etymology and spelling When it was introduced in the French newspaper ''Le Figaro'' in June 1833, the term 'phénakisticope' was explained to be from the root Greek word ''phenakistikos'' (or rather from φενακίζειν ''phenakizein''), meaning "deceiving" or "cheating", and ὄψ ''óps'', meaning "eye" or "face", so it was probably intended loosely as 'optical deception' or 'optical illusion'. The term phénakisticope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audiovisual Introductions In 1861
Audiovisual (AV) is electronic media possessing both a sound and a visual component, such as slide-tape presentations, films, television programs, corporate conferencing, church services, and live theater productions. Audiovisual service providers frequently offer web streaming, video conferencing, and live broadcast services. Computer-based audiovisual equipment is often used in education, with many schools and universities installing projection equipment and using interactive whiteboard technology. Components Aside from equipment installation, two significant elements of audiovisual are wiring and system control. If either of these components are faulty or missing, the system may not demonstrate optimal performance. Wiring is a skill that not only requires proper cable rating selection based on a number of factors, including distance to the main rack, frequency and fire codes, but wires should also be out of sight, behind the walls and in the ceiling, when possible.

Photographic Techniques
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose ...
