Camera anti-shake 5Meg 8Meg, 12Meg The pixels of smartphones with high-pixel cameras are getting closer and closer to DSC. However, high-pixel mobile phone cameras do not contain some optical or mechanical components of DSC. This lack of hardware will undoubtedly make the camera phone's camera effect worse than that of DSC.
The introduction of anti-shake technology can make the effect of high-pixel cameras closer to DSC. At present, the anti-shake technology of our cameras mainly uses the following types: Optical Image Stabilizer (optical anti-shake, hereinafter referred to as OIS), mobile CMOS chip surface, algorithmic anti-shake, JPEG transmission, High-ISO, MIPI transmission. Among the several technologies listed, we currently use algorithmic anti-shake, JPEG transmission, High-ISO, and MIPI transmission. It is expected that OIS will be used in the future. Here are some commonly used methods to prevent hand shake.
Anti-shake through the lens group mainly relies on the magnetic force to wrap the suspended lens, thereby effectively overcoming image blur caused by camera vibration. This effect is more obvious for digital cameras with large zoom lenses. Usually, the gyroscope in the lens detects small movements, and transmits the signal to the microprocessor to immediately calculate the amount of displacement that needs to be compensated, and then uses the compensation lens group to compensate according to the direction and displacement of the lens, thereby effectively overcoming image blur caused by camera vibration. 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 handheld shooting will not produce blur. The effect is very obvious for beginners. In addition to, in telephoto digital cameras, the effect is also immediate.
Electronic anti-shake technology utilizes dynamic vectors for shake detection. The swing direction and amount of the image are grasped based on the dynamic vector, and this is used as a reference to move the image position in parallel, thereby generating a shake-free dynamic image.
Continuous shooting anti-shake is a more compromise method. This mode of anti-shake allows the phone to continuously shoot the same photo at the fastest speed, usually 8 to 10 photos, and then selects the clearest photo through system processing to achieve anti-shake purposes.
For example, Best Shot in Samsung Galaxy S3 takes 8 photos of the same scene in a continuous shooting mode, and then selects the best one. Anti-shake shooting in this way is also a way to get clear photos.
Now APTINA, OVT, FUJITSU, and NEC all use the High-ISO method to prevent hand shake. This anti-shake effect has an impact on the image, that is, it introduces a certain amount of noise, but this is the cheapest anti-shake method and is easy to implement.
Anti-shake through the special internal structure of Jingdu. Including Nikon VR anti-shake, Canon IS anti-shake, Panasonic MEGA OIS anti-shake, Sigma OS anti-shake, Sony SuperSterdy Shot, etc. This method is currently the most common.
Body anti-shake technology. Proposed by Konica Minolta and currently used in Sony digital SLR cameras. On March 31, 2006, Konica Minolta announced its withdrawal from the camera business and decided to transfer some assets related to its imaging company's digital SLR cameras to Sony Corporation.
"Natural anti-shake" technology that increases ISO value. The representative manufacturer of this technology is Fujifilm.
Post-production anti-shake processing. Perform image sharpening and other processing, such as Samsung's ASR anti-shake, which uses this method.
An anti-shake method that has a shake sensing device but does not perform physical compensation. It was first used by Sanyo in the newly launched CG6 digital camera.
