Bob pushed the shutter button and … nothing happens. The stock passed into the hands of his son, and the real picture took was one of the POM a cheerleader-pom's. Bob lost contact. He resisted an insane stimulus to slam the camera to the ground and jump on it.

It was his first digital camera, and Bob had just had an unpleasant surprise. He had used film cameras all his life, but when his Yashica went into the shop a friend loaned him a> digital camera. Naively decided to take some action scenes and the insane "function" discovered by digital cameras – the shutter lag.

Crazy and frustrating

Articles on this topic have attributed Shutter

1. The camera system focus

2. The time that the machine for the digital imaging

3. Answer photographer

Numbers one and three times has been that most digital cameras useaccustomed. Most have used a camera, and I know it takes a few milliseconds to concentrate.

The no-brainer solution is to increase the lens aperture to reduce depth of field, or the camera aimed at the object you want to be in focus and half press the shutter button to tell "what focus the camera on, then move the camera to the center and push the rest of the trip.

Regarding the human reaction time, well, not really changed much for users of the filmCameras, and people to take action shots usually get what they want to know.

So let's at number 2, the time needed to process the image.

Time to do TRANSFORMATION

Image processing (so the camera can be ready for the next) occurs in several steps to get from the image sensor is moved to flash memory card:

1. Color corrections. The camera has examined about every single charge coupled device (CCD) element on the photo-sensor. It adds green, blue and redto achieve the right balance of color. For a 3-megapixel camera, the processor has to make 9 million calculations.

2. Sharpness. This increases the contrast with the definition and sharpness edges.

3. Compression. This process sets the 12 to 14 bits of each CCD sensor to 16 bits of "filler" information and is compressed to 8 bits. This compresses the file size to 9 megabytes.

These steps require a tremendous amount of computing time. No wonder Bob missed hisShot!

CATCH THE ACTION

There are two possibilities for the capture of measures:

1. The "Follow mode". If the camera has this mode, you can move a series of blows by a rapid event. This requires a camera with a large "buffer" to keep the photos for processing.

2. Anticipating shots by pressing and holding the shutter button before the event. This requires the ability of future, which most of us did not foresee.

THE FUTURE OF FASTERSHOOTING

Obviously, everyone would be simplified if micro processing were faster. Even with large buffers, the speed at which data is transmitted to the processor, transmitted by the speed at which data is prohibited by the CCD. Micro processing speed is the bottleneck next.

Faster clock speed and the speed of data transfer could reduce or even eliminate "shutter lag" time. There are various technologies behind the scenes, the hope

1. Nanotubes and nanowires technologies. Theseare both children of "nanotechnology", the ability of small machines on the "nano" level, a billionth of a meter in height and not as a millionth of a meter) (micrometers and offer the hope of a clock speed of 500 GHz or do more.

2. DNA Yes, you heard right. Computing based on DNA strands in which information is stored and processed.

3. Other materials

gallium arsenide or a much faster speed is used for years for military purposes.

silicon-germanium chips orIncrease the transmission of light signals to silicon. This tradition has worked better to extremely low temperatures, but computer simulations have shown that they can approach 1000 GHz (1 THz) at room temperature.

Indium antimonide o. Much faster than silicon —

oOptical transistors. A glass material known as chalcogenide, a switch will be changed as a property of refraction. No need to translate the photon into something else.

coated or viruses. TheRecent research on the virus coating with a conductive material. Much higher speeds can be obtained at the molecular level. This will give new meaning to the term "computer virus".

4. Parallel Processing. As we have noted recently, the war between Intel and AMD for the number of parallel processors crammed into a CPU, digital camera processing would benefit from parallel processors handling of focus, clarity and pressing.

5. Software. ImprovementTeaching efficiency, reducing lines of code could simplify the whole process.

HOLD ON AND WAIT FOR THE FUTURE

The real solution to this annoying shutter lag seems to be the material of the processor is built, as well as advances in software.

But we have come to for a while 'to wait. Although several alternative materials have been around for a while ', everything else is still in research and development. Even if he slipslaboratories, it is likely that your future digital camera cost about $ 10,000 – $ 15,000.

A nice price tag for the ability to take pictures as fast as a camera! Continued …

Apart from the delay, the digital movie cameras, it is only when the photo is captured from the memory card. The new technology is worth it.

The owners of digital cameras are well known known for their ability to wait … they try desperately to beat the shutterGet the fleeting smile, her new baby, or football, which is then passed into the hands of eighteen, when the scores winning touchdown.
