## Abstract

An apparatus and method is provided for controlling a virtual camera. The virtual camera is positioned in a first position and a first direction while an object is in a first state and the virtual camera is moved to a second position and second direction when the object transitions from a first state to a second state. The virtual camera is held in the second position and second direction while the object is in the second state and then moves back to the first position and first direction when the object transitions from the second state back to the first state. While the virtual camera is in the second position and second direction, the lowest part of the object is made more easily viewable.
