DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION.

Fig. 1 illustrates a flip-style mobile cellular telephone 10 that operates as an electronic imaging device. The device 10 comprises: a user input unit 20; a display unit 30; an imaging unit 40 and an image sensor housing 50.

The input unit 20 is, in this example, substantially cuboidal. Its extends lengthwise 24, in an orthogonal direction from the first fixed axis 1 , from a top edge to termination at a bottom edge. Side edges extend lengthwise between the top and bottom edges. The user input unit 20 comprises a user input device, such as a keypad, which is presented in its front face 22.

The display unit 30 comprises a display 31 and is mounted via hinge 61 for approximately 180 degree pivotal movement, relative to the user input unit 20, about the first fixed axis 1. The display unit 30 comprises a display portion 32 and a support portion 34 that couples the display portion 32 to the user input unit 20. The support portion 34is mounted via hinge 61 for approximately 180 degree pivotal movement, relative to the user input portion 20, about the first fixed axis 1. The display portion 32, which includes the display 31 , is mounted via a swivel 63 for 360 degree rotational movement, relative to the support portion, about a third axis 3 that moves as the support portion 34 rotates.

The imaging unit 40 is mounted via a swivel 62 for 360 degree rotation about a second fixed axis 2 that is orthogonal to the first fixed axis 1. The second fixed axis 2 is substantially parallel to the front face 22 and side edges of the user input unit 20 and passes centrally through the imaging unit. The imaging unit 40 extends, parallel to the second fixed axis 2, adjacent the side edge of the user input unit 20 for at least a portion of the user input unit's length 24.

The image sensor housing 50, in this embodiment is fixed, and connected to the imaging unit 40 via the swivel 62. The image sensor housing 50 extends, parallel to the second fixed axis, adjacent the side edge of the user input unit 20 for at least a portion of the user input unit's length 24. The image sensor housing 50 and the imaging unit 40 together extend along the whole length 24 of the side edge of the user input unit 20, which is longer that the top/bottom edges.

As shown more clearly in Fig. 2, the image sensor housing 50 houses a camera module 47 that comprises one or. more image sensors and a lens aperture 49. The camera module 47 is suitable for capturing still and video images and is aligned with the second fixed axis 2. The swivel 62 is provided by a journal comprising an inner and outer tube. One tube is connected to the base of the imaging unit 40 and the other tube is connected to the top of the image sensor housing. As the imaging unit 40 rotates one of the tubes rotates within the other. The lens aperture 49 is aligned with the interior of the inner tube, which provides a light path from the imaging unit 40.

The imaging unit 40 has a single aperture 42 in a sidewall and at least one optic for turning the light that arrives at the aperture 42 through a right-angle and directing it through the lens aperture 49 of the camera module 47. The aperture 42 supports a lens 44 which collects the light and directs to onto a prism (or mirror) 46 which turns the light. When the imaging unit 40 rotates the aperture 42, lens 44 and prism 46 rotate together but the camera module 47 remains stationary. • In a modification to this embodiment, the camera module 47 is integrated into the imaging unit 40. When the imaging unit rotates the aperture 42, lens 44, prism 46 and camera module rotate together. The camera module remains aligned parallel to the second axis 2. This embodiment may improve durability as the alignment of the sensor is independent of the rotation of the imaging unit 40.

In an alternative embodiment, the camera module 47 is integrated into the imaging unit 40 and it is aligned perpendicular to the second axis 2 so that its aperture 49 is aligned with the aperture 42 of the imaging unit. In this embodiment a prism (or mirror) 46 is not required as not light turning is required. When the imaging unit rotates the aperture 42, lens 44, and camera module 47 rotate together. This embodiment has cost and durability advantages.

The imaging unit 40 may rotate by 90 degree increments about the second axis 2 to one of four mutually orthogonal positions. The aperture 42 may face towards the hinge 61 (Fig. 1 , 3A, 3B, 7), towards the front (Fig 6.), towards the side (Fig. 2, 4) and towards the rear (Fig 5). When the aperture 42 faces towards the hinge 61 , the imaging unit 40 is stowed. The proximity of the aperture 42 to the hinge 61 protects the lens 44 from damage. In this position the imaging unit 40 is also less susceptible to damage by knocking. A servo motor is used to rotate the imaging unit 40 about the second axis 2.

Preferably, the servo motor is located in the user input unit 20, close to the image sensor housing 50 and just below the imaging unit 40.

The electronic imaging device 10 can operate in a number of different modes and can change between these modes. Each mode uses or may uses a different physical configuration of the device 10.

Mobile cellular telephone configurations are illustrated in Fig 3A and Fig 3B.

In this configuration, the imaging unit 40 is rotated 90 degrees anti-clockwise about the second axis 2, the support portion 34 is rotated 180 degrees about the first axis 1 , and the display portion 32 is rotated through 180 degrees about the third axis 3 so that the display 31 and aperture 42 point in opposite directions. The image displayed in the display 31 is automatically rotated by 90 degrees to correctly orient it.
