PORTABLE ELECTRONIC DEVICE

摘要

When a projector built into a mobile electronic device is in use (Yes at Step S101), it is determined whether an attitude of the projector is changed or the projector is moved (Step S102). If it is determined as Yes at Step S102, a movement distance and a movement direction of a projection area are determined based on a movement of the projector (Step S103). Next, the projection area of the projector is moved based on the movement distance and the movement direction determined at Step S103, and an image projected within the projection area is changed (Step S104).
