What does the stabilizer mode of Canon lens mean?
Mainly refers to the digital camera to speed up the shutter at the same time using the forced increase of CCD photosensitive parameters, and the image obtained on the CCD is analyzed, and then the edge image is used for anti-shake compensation. Electronic image stabilization is actually a technology to compensate for jitter by reducing image quality, trying to strike a balance between image quality and image jitter.
Extended data
Electronic anti-shake uses digital circuit to process the picture and produce anti-shake effect. When the anti-shake circuit works, the shot picture is only about 90% of the actual picture, and then the digital circuit makes fuzzy judgment on the camera shake direction, and then uses the remaining 10% picture for shake compensation. This method is characterized by low cost, but it reduces the utilization rate of CCD and will bring some losses to the picture clarity.
Electronic image stabilization is to analyze the image on CCD, and then use the edge image to compensate. Just like optical zoom and digital zoom, it is only post-processing the collected data, which has no practical effect. On the contrary, it damages the image quality to some extent. There are Casio, Kodak and Fuji which use electronic anti-shake technology on the market.
Electronic anti-shake technology is to "work hard" on the CCD of the product. Different from electronic image stabilization, optical image stabilization technology mainly makes a fuss about the lens, which is the most essential difference between them. The application of electronic anti-shake technology means that any lens can enjoy the anti-shake function without increasing the cost.
