Abstract

A portable terminal apparatus is provided that enables a mobile TV reception function to be added easily even to a main CPU that does not have a dedicated mobile TV interface. There are provided a cellular baseband LSI 110 that performs overall control of a portable terminal apparatus 100 and is also connected to a mobile TV back-end processing LSI 120 by a host I/F 141, camera I/F 142, and audio I/F 143, and a mobile TV back-end processing LSI 120 that implements a mobile TV function, wherein mobile TV back-end processing LSI 120 includes a selection circuit 122 that selects a video signal from a mobile phone camera module 125 or a mobile TV video signal based on a control signal from cellular baseband LSI 110, and outputs one or other video signal to camera I/F 142.

Claims

1. A portable terminal apparatus comprising:

an external specific function section that executes a specific program;

a host interface that controls said external specific function section;

a camera interface; and

a control section that performs control for selecting output from said external specific function section or input to said camera interface, and connecting that selected signal to said camera interface.

2. The portable terminal apparatus according to claim 1, wherein said camera interface inputs imaging data from a camera module.

3. The portable terminal apparatus according to claim 1, wherein said external specific function section is a mobile TV module that receives mobile TV.

4. The portable terminal apparatus according to claim 1, wherein said control section combines output from said external specific function section and input to said camera interface, and performs control for connecting that combined signal to said camera interface.

5. The portable terminal apparatus according to claim 1, wherein:

said external specific function section comprises;

a function-section-side camera interface with an identical function to said camera interface; and

a selection section that selects output from said external specific function section or input to said function-section-side camera interface, and

said external specific function section inputs a signal selected by said selection section to said camera interface.

6. The portable terminal apparatus according to claim 1, wherein:

said external specific function section comprises;

a function-section-side camera interface with an identical function to said camera interface; and

a combining section that combines output from said external specific function section with input to said function-section-side camera interface, and

said external specific function section inputs a signal combined by said combining section to said camera interface.
