  • Patent number: 7257830
    Abstract: A mobile electronic apparatus functions as an image medium reproducer, and, in particular, a moving image, such as a DVD reproducer. The mobile electronic apparatus has a mobile body, and a mobile stand detachably connectable with the mobile body. While the mobile apparatus body is connected to the mobile apparatus stand, the mobile apparatus body performs auralization and visualization of at least one A/V (Audio/Video) signal based on at least one input A/V signal from an A/V storage medium and at least one input body control signal output from the mobile apparatus stand, and outputs at least one stand control signal controlling the A/V signal output by the mobile apparatus stand. When the mobile apparatus body is disconnected from the mobile apparatus stand, the mobile apparatus body operates as an independent mobile electronic apparatus.
