MPO Files

MPO kitty!

What are they

MPO (Multi-Picture Object Bitmap) Files are stereoscopic images, comprised of two overlapping 2D JPEG images. Each is used to represent the "left" and "right" view respectively, simulating a 3D effect. The 3D view of the Nintendo 3DS is created using MPO images. A device which does not support MPO cannot open and display the 3D image and may only display a JPG image version.

Some Digital Cameras can snap MPO Images, using two sensors spaced apart in the average distance of two human eyes.
