Standard Definition (SD) 960×540
The standard definition camera mode is the default image mode for the objective camera. In this mode, the camera captures images at 1920×1080 and reduces the resolution to 960×540 by halving and averaging the vertical and horizontal resolution. This has the effect of reducing the resolution and reducing camera noise. The standard definition camera mode is up to four times faster than the high definition camera mode.
High Definition (HD) 1920×1080
The high definition camera mode is the full resolution mode of the objective camera. In this mode, the camera captures each image at its native resolution. This camera mode provides the greatest resolution but it is up to four times slower than the standard definition mode.
