What is the difference between OIS and VDIS?

OIS: Is the Optical Image Stabilization:  The gyro-sensors measure movements and send this data to a “microcenter,” which then moves the lens to offset the motion. In short, OIS mechanically moves the image sensor in response to any shaking detected in your phone.

VDIS: Video Digital Image Stabilization, or DIS, reduces the level of blur or distortion in your videos that can result from unsteady or shaky movement. By enhancing sensitivity and increasing the shutter speed, or by moving the camera sensor in the opposite direction to the detected movement, your videos can come out clear.
