Optical image stabilization is a kind of anti-shake technology that is most recognized by the public at present. It compensates the optical path where hand shake occurs through movable components, so as to achieve the effect of reducing photo blur. At present, the optical image stabilization technology is divided into two major groups, namely the lens-shifting optical image stabilization represented by the lens manufacturers, and the CCD portable optical image stabilization represented by the emerging electronics manufacturers. However, because optical image stabilization requires the use of additional components, which also leads to high cost of optical image stabilization systems, the market price of models equipped with optical image stabilization systems is still relatively expensive.
Optical image stabilization relies on the special lens or CCD sensor structure to minimize the image instability caused by jitter during use by the operator.
Optical image stabilization technology detects tiny movements in the gyro inside the lens, and transmits the signal to the microprocessor to immediately calculate the amount of displacement that needs to be compensated, and then compensates the lens group to determine the direction of the lens and the amount of displacement. Compensation, which effectively overcomes image blur caused by camera shake. Canon's IS system requires only a short time to complete the movement of the IS lens group, so the effect is still very good. It is generally effective to prevent the shutter time from being shorter than 1/60s.
Anti-shake type
The effect of the optical image stabilization function is quite obvious. Under normal circumstances, turning on this function can increase the shutter speed by 2-3 steps, so that the hand-held shooting will not produce ambiguous phenomenon. For beginners, the effect is very obvious. In a telephoto type digital camera, the effect is immediate.
Optical image stabilization is a kind of image stabilization technology that is most recognized by the public. It uses a movable component to compensate for the optical path where hand shake is occurring, so as to reduce the effect of blurring the photograph. Optical anti-shake technology is divided into two major factions, namely the lens mobile optical image stabilization represented by the lens manufacturers, and the CCD mobile optical image stabilization represented by emerging electronics manufacturers. However, because optical image stabilization requires the use of additional components, which also leads to high cost of optical image stabilization systems, the market price of models equipped with optical image stabilization systems is still relatively expensive.
<br> <br> lens anti-shake image stabilization achieved by the main lens group relies on magnetic suspension package lens, so as to effectively overcome the image blur caused by camera vibration, which for large zoom digital cameras can play a more pronounced effect. Usually, the gyroscope in the lens detects a slight movement, and transmits the signal to the microprocessor to immediately calculate the amount of displacement that needs to be compensated. Then, by compensating the lens group, the gyro will be compensated according to the shake direction and displacement of the lens. The group adjusts the position and angle accordingly to keep the light path stable, effectively overcoming the image blur caused by the camera's vibration.
CCD stabilization
The principle of anti-shake achieved by CCD is to rely on the floating of the CCD to achieve anti-shake. The principle is to first fix the CCD on a bracket that can move up and down, and to sense the direction and amplitude of camera shake by the gyro. Then the sensor sends the data to the processor for screening and amplification, and calculates the amount of CCD movement that can offset the jitter. .
