The EIS electronic anti-shake effect of the G1 camera module

Huaxing Video uses iCatch chip to develop the G1 camera module. The ISP algorithm of the iCatch chip supports electronic image stabilization (EIS), has multi-axis image stabilization technology, intelligently analyzes the motion posture of sensor information, corrects dynamic videos through precise compensation, and effectively reduces the impact on video imaging caused by external environment shaking or jittering.

EIS electronic anti-shake technology is a video stabilization technology that can effectively reduce video jitter and blur caused by camera vibration. The principle of electronic anti-shake is to shoot a stable reference image, use this image as a template, and then compare the images in real-time during the subsequent shooting. The displacement of the captured image relative to the template image is determined through calculation. Then, this displacement information can be used to perform real-time stabilization processing on the captured image to achieve the anti-shake effect. EIS electronic anti-shake is actually a technology that compensates for jitter by reducing image quality.

The G1 camera module enables EIS electronic anti-shake

The G1 camera module disables EIS electronic anti-shake by default. If you need to enable it, you can set it through the APP, touch screen, or configuration file.

The following is the EIS electronic anti-shake setting in the configuration file. The value after "=" on the line of "fs_" is configurable. To enable EIS anti-shake, change the value "0" after "=" in the configuration file to "1", save the modification, power off after power on, and power on again for the modification to take effect.

Upgrade of the electronic anti-shake algorithm of the iCatch chip

EIS electronic anti-shake technology has been widely applied in the field of modern video shooting. It can ensure the stability and clarity of the video image and enhance the visual experience and perception effect of users. With the continuous development and improvement of technology, EIS electronic anti-shake technology will become more and more perfect and efficient.

The upcoming iCatch V57 chip, the EIS electronic anti-shake algorithm of the chip is upgraded, and it can achieve horizon anti-shake effect. It not only effectively offsets the jitter in all directions of the camera, but also performs horizontal correction for the horizon tilt. Even after experiencing severe bumps or rotations, the image can always remain horizontally stable.
