How has the history of cameras changed in movies?

More than 40 years ago, Ampex introduced the world's first practical camera, using a camera tube as a camera element.

1976, JVC company launched the first home camera, which adopted VHS format independently developed by JVC. Later, after several upgrades, the size of the stored video tape was reduced and evolved into an early "big video tape" that could be played on TV in China.

In 1980s, V8 camera and Hi8 camera appeared one after another, using 8mm video tape.

1In July, 1995, Sony and Panasonic simultaneously launched the first digital (mini-tape) camera, which made the original enthusiasts accustomed to high-end analog home Hi8 and other machines see the potential of obtaining professional machine quality at the price of home products. In particular, the practice of using DV in image creation has made DV go beyond the original functional scope, and it has been favored by many video producers and enthusiasts. The appearance of home digital camera is a sign of updating and truly digitizing the recording format of home camera, which has a very broad development prospect.

Second, the development of photosensitive elements.

1On July 24th, 995, Sony announced the first digital camera DCR-VX1000, which revolutionized the use of mini-tapes as storage media and adopted the structure of 3CCD sensor.

In mid-2003, Panasonic introduced GS70, a low-priced household model with a price of less than 10,000 yuan, which further narrowed the distance between 3cd and people.

In mid-2005, the amazing 3CMOS digital camera-PC1000e was born.

Third, the lens

Note: Zeiss and Leica are the most famous lens brands. At present, Panasonic is the only DV manufacturer using Leica lens, and Sony is the only DV manufacturer using Zeiss lens.

1In July, 996, Sony's CCD-TR555 with Zeiss lens came out.

In September 2000, Panasonic released NV-MX3000 equipped with Lycra lens from Germany, which was also the top 3cd model at that time.

Fourthly, touch screen technology.

1June, 999, Sony DCR-PC3 launched a touchable display screen, which can operate DV through the touch screen. At present, only Sony has it.

Fifth, the continuous improvement of CCD pixels

Generally, the total pixel of low-end CCD is 800,000 images, of which 400,000 are dynamic, and other pixels are used to compensate noise and anti-shake function. Although we all know that dynamic DV only needs 465,438+0-680,000 images, it still can't stop the development of high pixels.

In September 2002, Sony released the first 2 1 10000 pixel DCR-IP220.

In 2003, Sony released the first DCR PC 330 equipped with a 3.3 megapixel CCD.

Sixth, the static pixel temperature is rising.

In 2004, Panasonic introduced the 3 CD 4 megapixel GS400.

The MC500 of 3CCD released by JVC in 2005 has the function of 5 million pixels still shooting.

Note: They used some techniques to improve the pixels. At the same pixel level, the picture quality is not as good as that of DC.

Seven, the arrival of new formats

Since the first home camera came out in 1985, the camera has gone through VHS, 8mm, Hi8 and MINIDV-its format standards have continuously improved the quality of image recording, so it is time to welcome a new format standard.

On September 3rd, 2003, Canon, Sharp, Sony and JVC jointly published the HDV standard. Its concept is to develop a portable camera for home use, which can conveniently record high-quality and high-definition images. HDV format can be used with the existing niniDV tape, and it can be used as a recording medium.

In June 2004, Sony launched the world's first civilian high-definition camera-Sony HDR-FX 1080i. It also marks the arrival of the high-definition DV era.

Eight, the arrival of the storage revolution

1995-2005 development of storage media

Before 2000, all digital cameras in China used mini-DV tape as the main storage medium, and generally recorded for 60 minutes. Some models have LP function and can record for 90 minutes (the tape speed in SP mode is 33.8 mm/s). DV system has been further developed into a professional machine by professional manufacturers because of its high image quality and sound quality, such as Sony's DVCAM and Panasonic's DVCPRO. , use L-type or M-type tape, and record 180 minutes at most. Both DVCAM and DVCPRO are backward compatible DV systems, but they are incompatible. Mini DV tapes can only be played on professional machines with tape adapters (non-recordable). Up to now, mini-tape is still a common mainstream DV storage medium in the market, and it is still a widely accepted storage method.

2000-200 1 transitional storage medium

In the course of 10 years, storage media has not only stayed on mini-tapes, but also some unforgettable non-mini tape product lines have appeared. Although they have never shaken the status of mini-tapes, they have indelible glory.

Mddisc was born with MD storage.

In 200 1 year, Sony released its original "MICROMV" format camera, and MicroMV tape is commonly known as MV tape.
