Who invented the digital camera and who invented the camera

In 1951, the Bin Crossbye laboratory invented the Digital Video Recorder (VTR), a new machine that could record the current pulses of television broadcasts onto tape. By 1956, video recorders were mass-produced. It is seen as produced by electronic imaging technology.

1. Digital camera is a product integrating optics, machinery and electronics. It integrates the conversion, storage and transmission of image information, and has the characteristics of digital access mode, interactive processing with computer and real-time shooting. The light enters the camera through the lens or lens group, and is converted into a digital signal through the digital camera imaging element, and the digital signal is stored in the storage device through the image computing chip.

2. The imaging element of the digital camera is CCD or CMOS, which is characterized by the fact that when the light passes through, it can be converted into electronic signals according to the different rays. Digital cameras first appeared in the United States, more than 20 years ago, the United States used it to transmit to the ground via satellite**, and later digital photography turned to civilian use and continued to expand the scope of application.

Kodak. Kodak is a leading manufacturer of imaging products and related services, founded in 1880 and headquartered in Rochester, New York, USA.

A digital camera is a type of camera that uses an electronic sensor to convert optical images into electronic data. Unlike ordinary cameras, which rely on the chemical changes of silver bromide on film to record images, the sensor of a digital camera is a light-sensing charge-coupled device or a complementary oxide semiconductor of the genus Jin Qiqin.

The inventor of the camera was Daguerre of France.

In 1839, Daguerre made the first practical daguerreotype camera, which consisted of two wooden boxes, one of which was inserted into the other for focusing, and the lens cover was used as a shutter to control the ** time of up to 30 minutes, which could take clear images.

In general, the main components of a camera include the imaging element, the anechoic chamber, the imaging medium, and the imaging control structure. The imaging element can be imaging; The imaging medium is responsible for capturing and recording images; The darkroom provides a connection between the lens and the imaging medium and protects the imaging medium from interference; The control structure can change the way the image is imaged or macromed or recorded to the final image of the image. Aperture, shutter, focus control, etc.

Camera Classification:

1. SLR camera.

SLR digital camera refers to single-lens reflex digital camera, that is, digital digital, single, lens lens, reflex reflex English abbreviation DSLR. Representative models in the market are commonly found in Nikon, Canon, Pentax, Fujifilm, etc. This clump clump camera is generally larger and heavier than the slender cherry blossom.

2. Mirrorless camera.

Mirrorless camera contains two meanings: micro, miniature and small, single, interchangeable single-lens camera, that is to say, this word means that this kind of camera has a small size and SLR general image quality, that is, a miniature and compact camera with SLR performance is called a mirrorless camera.

3. Card camera.

There is no clear concept of card cameras in the industry, and only those small form factors, relatively light bodies, and ultra-thin and sleek designs are the main criteria for measuring these digital cameras.

4. Telephoto camera.

A telephoto digital camera is a model with a large optical zoom factor, and the larger the optical zoom factor, the farther the object can be captured. Representative models are: Minolta Z series, Panasonic FX series, Fujifilm S series, Kodak DX series, etc. <>

The camera was invented by Daguerre.

In 1839, Daguerre of France built the first practical silver disk camera. The basic idea is to take a copper plate with silver iodide on its surface**, then steam it with mercury and fix it with an ordinary salt solution to form a permanent image.

Later, Daguerre used this method to build the world's first camera. At the same time, Daguerre photography was the world's first successful method of photography.

It is generally believed to be L. Daguerre of France, see page.

The Greek philosopher Aristotle of the third century BC described a small hole in a dark house in which light appeared to be shadowed. In 1516, Leonard da Vince of Italy recorded the study of the image obscura. In 1611, the German Johnnec Kepler invented the adhesive lens in which two lenses with concave and convex lenses are bonded into one piece.

In 1666, Isaac Newton experimented with a three-beam mirror and discovered the phenomenon of hepticolor scattering of light. These great discoveries of mankind led to the invention of the European painting camera obscura, which used light passing through a lens to form an image for sketching, which was the earliest prototype of the camera. However, this is only limited to the formation of images, and how to preserve images has not yet reached a mature stage.

In 1837, the French stage artist Daguerre invented a photographic technique that can preserve the image with the chemical silver salt, which will change when exposed to light, called daguerreotype. Da Caire's initiative was made public in August 1839 when France** bought the rights to his invention to the world. Within a few years, daguerreotype photography quickly became popular in European countries and the world's advanced countries.

This is why most people recognize this era as the birth of photography.

This is a leap forward for photosensitive materials. In the same year, Kodak invented the world's first portable square box camera for mounting film With the development of photosensitive materials, in 1871, a dry plate coated with silver bromide photosensitive material appeared.

It was the man who invented the camera.
