OIS (Optical image stabilization)-It is the mechanism of make stable the focus of a camera lenses toward scene to prevent the blur image due to shaking of camera/phone. during taking of a photo/video the phone may shake due to our movement or for the shaky hand and hence we don’t get the desired clear image. If there is the feature of OIS in the camera, its lenses can adjust itself according to the movement hence we get clear image. The smartphone camera with the feature is good but it doesn’t come with all the smartphone except high priced smartphone.

EIS (electronic image stabilization)-Its main function is to stabilise the camera to get a clear image. As it uses its digital system to stabilise the image is not clear as the phone with OIS.
