Abstract
A portable telephone 1 is provided with a body 2 and a camera unit 3. In the camera unit 3, photography is switched to macro photography by pressing a macro button 22 on the body 2. In this way, the convenience of the portable telephone 1 is improved because an object in the very near distance can be photographed. The camera unit 3 is constructed so as to be freely rotatable in a direction Rc on a shaft of a connector C. Accordingly, a user can freely modify the photography direction of the camera unit 3, thereby increasing the freedom of photography and providing greater improvement in the convenience of the portable terminal.
Claims14
A portable terminal comprising:
- a body having a communication function;
- an image pick-up element for acquiring an object image data;
- an optical system for forming an object image on the image pick-up element;
- a camera housing the image pick-up element and the optical system;
- a connector which connects the camera and the body;
- and
- a moving mechanism for moving the optical system to a lens position for macro photography.
A portable terminal comprising:

- an image pick-up element;
- an optical system for forming an object image on the image pick-up element;
- a camera housing the image pick-up element and the optical system;
- a connector which connects the camera and the body;
- and
- a focusing mechanism for moving the optical system to a position for macro photography with in-focus state.
A driving method for moving a plurality of lens units from a first position for a first photography magnification to a second position for a second photography magnification, the driving method comprising:
- a setting process for setting the respective moving speeds of lens units in accordance with the moving distance of each lens unit moving from the first position to the second position;
- and
- a driving process for driving the lens units independently at the set moving speeds of the respective lens units.
A driving method for moving a plurality of lens units from a first position for a first photography magnification to a second position for a second photography magnification, and moving the lens units to a third position for a third photography magnification from the second position, the driving method comprising:
- a first driving process for driving the lens units from the first position to the second position;
- a stopping process for stopping the movement of a lens unit that reaches the second position;
- and
- a second driving process for driving the lens units from the second position to the third position after all lens units have arrived at the second position.
