Flash DV legitimate young

By Zou himfr

Innovations brought about by flash DV ---

DV-tape era of style has long been a history of disc-type DV has been old. High-tech industry is so brutal, so quick technological update, today's star will soon be eliminated.

Although hard drive-based DV is now the best time, but it is already feeling the pressure of rising star, flash memory-type DV has been less legitimate. New storage methods brought about by replacing DV

In 2009 at the same rapid.

Smaller

Take a look at our computer hard drive, and then look at the digital camera's memory card. Can understand, and hard drive-based DV compared to flash-type DV has a lot of natural advantages. Media update, making flash-type structure on DV in a significant improvement, small-scale implementation of easy, so manufacturers take full advantage of this, released in 2009 on some new manifestation of a lot of new models so that the weight of small incredible people can not only easily into pockets, but also as a card like a digital camera with wrist strap sets up at the wrist, is extremely convenient to carry.

More stable operation

No noise, and tape, CD-ROMs, hard disk storage medium is different flash media is not any mechanical drive structure, therefore greatly enhance the stability, even if it is accidentally dropped, but also not have to worry about data loss.

Rapid response

DV-type flash memory in the data read and write speed up faster than hard drive-based DV, together with the image processor with, not only can quickly enter the shooting status, in operation on the response time there was a marked shortening.

Low power consumption, and expand capacity

Abolished the power of mechanical body, the DV-type flash memory can be more long standby time. Airframe because of relatively simple structure, DV-type flash memory can be sealed up in the airframe to do more in place, such as waterproof, dust-proof can be achieved at low cost.

New characteristics of flash memory DV ---

Panasonic SDR-SW21

Panasonic SDR-SW Series is the biggest selling point of three anti-properties --- waterproof, shockproof and dustproof. Latest Products in the SDR-SW21 on airframe design and not much improvement, but in order to meet the market trend, has enriched the shell color. Storage area, not built space, will be entirely depend on the expansion memory card.

Samsung SMX-F34

With 680,000-pixel CCD, using the German Schneider lens, 42-fold with the standard Smart Zoom digital zoom compared to effectively reduce the damage on the screen. 2.7 inches wide LCD display, the use of large volumes of 16G flash memory as storage media, and is equipped with SD / SDHC slot to expand capacity. H.264 compression standard, users can directly record up to 8 hours of Standard Definition video. Will be automatically adjusted to 640x480 resolution (H.264/AAC/MP4) and network optimization. Not only can record 720 480 resolution motion video, but also can take 800 600 still images.

JVC GZ-HM200

The world's first dual SDHC memory card with flash memory high-definition, it does not built any space, and in the body has two card slots that can simultaneously insert two 32GB maximum capacity for the SDHC card, shooting at the time If the first card is full of information, that information will automatically be saved to second on SDHC cards. As a result, GZ-HM200 shooting up to 30 hours of HD video in no way inferior to the hard disk DV.

Sanyo DMX-HD2000

At design, the extension of the classic razor shape. Using a 1/2.5 inch CMOS sensor, pixel 800 has been elevated to the ten thousand, in addition to support 1080P Full HD output, also has 448 336 resolution 240fps and 192 108 resolution 600fps high-speed camera performance, add facial recognition, Face Priority AF, beauty mode characteristics model, burst speeds of up to 15, although only four million pixels. - 18423
