How to realize the anti-shake function in digital camera?

(1) At present, digital cameras with anti-shake function mainly include optical anti-shake and electronic anti-shake.

1, optical image stabilization: the "optical axis deviation" is corrected by the floating lens of the lens. The principle is that the tiny movement is detected by the gyroscope in the lens, and then the signal is transmitted to the microprocessor, and the processor immediately calculates the displacement to be compensated, and then compensates according to the shaking direction and displacement of the lens through the compensation lens group; So as to effectively overcome the image blur caused by camera vibration. This anti-shake technology requires high lens design and manufacture, and the cost is relatively high. The effect of optical anti-shake function is quite obvious. Generally speaking, turning on this function can improve the shutter speed of 2-3 gears, so that hand-held shooting will not be blurred, and the effect is very obvious for novices. Especially in large zoom cameras, the effect is more obvious; Because the bigger the zoom, even the slightest jitter is very obvious, and the demand for anti-shake function in telephoto is even greater. The best is Panasonic.

2. Electronic anti-shake: use CCD offset to realize anti-shake. The principle is: first, put the CCD on a bracket that can move up, down, left and right, and then when the gyro sensor detects the jitter, it will process the parameters such as the direction, speed and movement amount of the jitter, and calculate the CCD movement amount that is enough to offset the jitter. Compared with optical anti-shake technology, CCD anti-shake technology effectively avoids the spherical aberration problem caused by compensation method, and also solves the volume limitation problem that plagues SLR lens replacement. Moreover, the design of the lens is not limited by the anti-shake technology, so Ricoh R3 and R4 can realize a wide-angle optical zoom lens of 7. 1 times 28-200mm. But the effect is not as good as optical image stabilization.

Therefore, if you want to get a really good anti-shake effect, you should choose a digital camera with optical anti-shake; Or a digital camera with optical and electronic image stabilization.

(2) Through the understanding of anti-shake function, we can know that the use of anti-shake function can effectively overcome the image blur caused by camera vibration, so that hand-held shooting will not be blurred. Of course, if you have a pair of iron hands, it will work if you don't shake it. What's more, even with the anti-shake function, it's still not a problem when shooting at night. You still have to use a tripod-this is the best anti-shake tool. Therefore, if you use a tripod frequently, it doesn't matter whether it is anti-shake. Tripod is more useful than anti-shake function. If you don't have the habit of using a tripod, it is much better to have anti-shake, especially the telephoto lens, so as to avoid taking fake photos.

Secondly, in the current digital cameras, models suitable for home use can be said to account for the vast majority. Wide angle, telephoto, anti-shake, large screen, card machine, full automatic, full manual, multi-function and so on. All kinds, what to choose depends on your preferences and investment.
