The development of digital camera


Great digital cameras in the development process Records of the Historian


Since the camera in 1839 by the French inventor, has gone through nearly 200 years of development. In this 200 years, gone through a camera from a black-and-white to color, from a purely optical, mechanical structure for the evolution of the optical, mechanical, electronic three-in-one, from the traditional silver film to the development of today's digital memory as a record of the media. Wang Xiao Kan cloud cover eyes, instant Kuwata sea change, the emergence of digital cameras marked the official digital camera industry to a new era of development by leaps and bounds, people's lives resulting image has been completely changed.

Since October 17, 1969, the United States Institute of the Bell announced the invention of Smith and Powell "CCD" (charge-coupled device), after such sensitive components to further improve, finally widely used today. 4-color CCD, SUPER CCD, and other improvements to the latest version of the continuous emergence of a few pixels across the already tens of millions of pixels, and the effect imagery has also run in perfect.

After more than a decade of development, DC industry has long been out of their own childhood, the designs become more mature, increasingly powerful functions of the operation, and as further reduce manufacturing costs, the development of such products has revealed the unlimited development Signs.

Overall, DC industry more than a decade the development process always carried a "higher, faster, stronger, more humane," the development of the context, it is on the manufacturer's efforts, today's digital camera market Would become so prosperous and beautiful. People enjoy the convenience brought about by science and technology, still can not help Nianqi the early days of the birth of the digital camera through the bumpy road to this industry have a significant impact on some of the classic model is still difficult for people to forget.

Cambrian - the outbreak of major life

Many life suddenly appeared in the Cambrian, the entire Earth at night becomes a colorful, life is full of flavor, archaeologists of the reasons for its failure to give a clear answer so far. 80's digital camera industry is no different from the Cambrian, in less than 10 times, fast digital camera out of infancy and gradually learned how to go limp along, even though at that time the resolution is still very low, but many companies are involved in the So that the industry is full of vitality slowly.

Vicat Suo Nima (MABIKA) - the world's first photographic film do not have an electronic camera

In November 1973, Sony began the "electronic eyes" CCD research in technology continue to accumulate on the basis of its launch in 1981, the world's first photographic film do not have an electronic camera - video static, "Ma Weika (MABIKA) ". The camera uses 10 mm × 12 mm thin section of the CCD, the resolution is only 570 × 490 (27.9 million) pixels, for the first time will be replaced by optical signal transmission of electronic signals.

Followed by Panasonic, COPAL, Fuji, Canon, Nikon, and other companies have also started to develop the electronic camera, and in 1984-1986 have implemented their own prototype electronic cameras, the beginning of life on this big outbreak.

Sony MYC-A7AF - for the first time with a digital camera so that the pure physical methods of operation

DC industry in the development of a milestone in the history of the same camera 2 out of the hands of Sony, we can see that the company achieved this market position is by no means "Langdexuming." In 1986 Sony released a MYC-A7AF, for the first time with a digital camera so that the pure physical methods of operation, the 2-inch disc can be recorded on the still image, has also been extended to the pixel resolution of 380,000 pixels. Casio VS-101 - the first CMOS camera sensitive electronic devices

In 1987, Casio first put on sale in the market to use the CMOS sensor device of the VS-101 electronic cameras, although the resolution reached only 280,000 pixels, DC This is not good for the industry is of great significance.

Today, on the point of view, CMOS and CCD digital cameras in sensitive devices for the formal aspects of dust has settled, CMOS in addition to today's high-end Canon camera is also widely used on other manufacturers to have their products as CCD The dominant direction. It can not be denied, CMOS has a full-size, low power, and other advantages are indeed very attractive, but the drawbacks of the low dynamic range can not allow its people "at arm's length."

Canon RC-760 ----- the first 600,000 pixel models

Want to get closer to the traditional film camera effects to enhance resolution CCD pixels can be regarded as the most fundamental way to solve, but in the early stages of the birth of a digital camera, the pixels on a higher level you want it is easier said than done. Few years, manufacturers have been in the 300,000-pixel level remained difficult, until 1988 only by the Canon has introduced a 60-megapixel model RC-760.

This electronic camera using 2 / 3-inch 600,000-pixel CCD, the appearance of today look a little stiff, but this is the highest pixel that time machine, than today's price of a car is also expensive.

Cretaceous - ferocious dinosaurs

After a long life and the evolution of the evolution of the Cretaceous eventually gave birth to the more advanced forms of life, all of a sudden the world is becoming more popular again. 80's constant accumulation of technology for us to finally ushered in the age of 90 digital camera industry, real prosperity Since then, a digital camera to establish their basic survival mode.

Kodak DCS 100 - for the first time in the world to establish a digital camera, the general pattern
In 1990, Kodak introduced the DCS100 electronic cameras, for the first time in the world to establish a digital camera, the general pattern Since then, this model has become the industry standard.
For professional photographers who, if a new machine that they are familiar with the body and control model will undoubtedly start easier. In order to cater to this consumer psychology, Kodak DCS100 application for a well-known at the time of the Nikon F3 body, in addition to in-house function screens and made big changes to the motor, with all the features generally goes for the F3 and is compatible with Most of the Nikon camera, it is well considered.
This digital SLR uses 1,400,000 pixels has a 20.5 x 16.4mm CCD, optical variable multiple of 1.8X, but was limited to the skill level to it is not equipped with built-in memory, only with a heavy external storage unit ( DSU) use. DSU with today's base of the camera almost to the battery as the energy drive, 200MB built-in memory can store 150 uncompressed RAW photos.

Viewfinder mode with than today's machines are very primitive, the photographer can use the camera's optical viewfinder or the DSU on the 4-inch LCD screen LCD viewfinder, although not very convenient, but at the time but very high. At that time the machine's price is equivalent to today's 225,000 yuan, is too far off your ah.

DCS100 in the success, in 1992, Kodak introduced a follow-up DCS100 models DCS200, it finally shake off the burden of the DSU, was placed in storage within the body, so shoot it out with a very happy the .

Nikon / Fuji E2/E2s-- Nikon, Fuji together the two giants of the digital SLR
Whether Kodak or Canon, early in the product design are all used in the original traditional film camera body, although it allows professional photographers who feel affinity products, but more than 1 products will inevitably create boring Feeling. In 1995, Nikon, Fuji giant to launch two completely new design E2/E2s, it will not copy the old tradition of the fuselage, the use of integrated design, which can easily create a fresh experience.

This digital SLR resolution of only 1,300,000 pixels, with the same period of Kodak DCS460 has 6,000,000 pixels compared to a difference. E2/E2s the most special thing is that the use of newly developed Nikon ROS optical system through a set of optical components will be light to the project area is less than 35mm film of the CCD, the camera on the basis of this perspective may remain the same, but Limited effective aperture serious shrinking, image quality has been a greater impact.

Integrated design so that the appearance of the machine appears to be more concise, but the internal structure of the complex has inevitably resulted in the appearance of volume expansion, the total weight is also showing signs of running out of control. The machine for Nikon digital SLR research and development and accumulated a lot of experience, it listed four years after Nikon introduced on the epoch-making D1, a digital camera industry of the Cretaceous era will be completely over.


Jurassic - a dangerous jungle

Jurassic biological category has been very complete, and there have moderate herbivorous dinosaurs submissive, has a lively and active white face of a monkey, there is a very cruel Tyrannosaurus, as each animal to survive in this world we must find ways Become more powerful, is the only way to the law of the jungle in this jungle over the easy comfort.

Nikon D1 - the first self-developed Nikon digital SLR
In June 1999, Nikon has finally launched its first self-developed digital SLR-D1, with much lower than the Kodak DCS series of cameras to create digital SLR price of a new era of civilian.

The digital SLR is used by the body in the F5 on the basis of traditional camera through the modifications completed, remains a highly attractive professional temperament. It built 2.74 million-pixel CCD, ISO sensitivity 200-1600, using CF card / IBM as a micro hard disk storage medium to support the file format, including JPEG, TIFF, RAW three, the price of 5580 U.S. dollars, in view of today still appears to be Expensive.

Canon EOS 1D - Canon's digital single myth
For a long time, the pixel resolution for the same time, manufacturers in the shooting competition at the same speed in full swing. In order to completely beyond Nikon D1 created the myth, Canon in September 2001 launch of a dedicated rapid shooting EOS 1D, in order to speed and technical specifications on all-round pressure over the Nikon D1, the achievements of the new generation of DC industry legend .

The digital SLR has a 4,000,000-pixel resolution, ISO sensitivity 100-1600, and using CF card / IBM as a micro hard disk storage medium, the price of 7,000 dollars.


Olympus E-1 - 4 / 3 system of representative
As early as notebook manufacturers, in order to catch up with rivals to create the biggest trouble makers in the digital SLR product design should be deliberately avoided compatible with rival products, so that any brand of digital camera components GM can not, in the damaged components only after the user to buy the same brand of replacement products, which manufacturers can obtain the maximum profit.

Today's notebook has already done compatible with each other, which can be described as a computer vendor performance in an increasingly open, and the digital camera industry changes are also taking place. In December 2003, Olympus released with Kodak, Fuji two companies jointly developed the "4 / 3 system" E-1.

4 / 3 system provides for the area CCD sensor device, CCD camera and the distance between the lens and the diameter, so that any use of the system of digital single-lens reflex camera can be easily compatible with each other, which in previous products China is absolutely unthinkable.

E-1 uses 5,000,000 pixels CCD, ISO sensitivity range of 100-800, using CF card as the storage medium, in support of JPEG, RAW, TIFF file format. Published at the beginning of the selling price as high as 16,000 yuan.

Canon EOS 300D - civilians generation of digital SLR Wang

Digital SLR powerful, beautifully-definition film, but its high price is not approaching the biggest obstacle to the civilian population. In order to successfully complete the course of the popularity of digital single-lens reflex, manufacturers are always in their brains to find ways to cut costs, it is in their unremitting efforts of a group of civilians reasonably priced digital SLR finally emerged, and Canon E0S 300D will no doubt be considered the pioneer of this process.

In August 2003, Canon introduced the use of plastic body of the EOS 300D, which combines the older EOS-10D's CMOS sensor devices used, for the first time lower than the price of 1000 U.S. dollars, which completely changed the original digital camera market competition .

The use of camera 6,300,000 pixels CCD, ISO sensitivity 100-1600, using the CF card as the storage medium. Designs applied silver, gray and black tricolor, and the overall feel is still not bad.



Written on the last

The evolution of life and never stagnant, and the DC industry has also never end. In the pixel resolution of climbing under the premise that today's digital camera makers is no longer the target of upgrading our competitiveness as the only means to make our products more convenient, easy-to-use, more humane and friendly It has long been a design of their products to the latest consensus.
