It can also crop, scale and rotate images and it features a red-eye removal functionality.
This is obvious because the red-eye effect is most apparent when photographing dark adapted subjects, hence with fully dilated pupils.
An example of manipulation with the camera itself is automatic red-eye removal in the image.
