Embodiment Construction

[0014] FIG. 1 is a block diagram of an exemplary multifunctional electronic device in accordance with the present invention. This exemplary embodiment combines a cell phone and a camera in a single unit, referred to herein as camera phone 100 . However, the present invention is not limited to use in camera phones 100, but can be implemented in other electronic devices that require a keypad to be viewed from two or more different directions.

[0015] The camera phone 100 includes a camera component 110 and a communication circuit 120 . The camera assembly 100 includes a lens assembly 112 , an image sensor 114 and an image processor 116 . The lens assembly 112 may include a single lens or multiple lenses, and collects light and focuses the light on the image sensor 114 . The image sensor 114 captures images formed by the light collected and focused by the lens assembly 112 . The image sensor 114 may be any conventional image sensor 114, such as a Charge Coupled Device (CCD) o...

Abstract

An electronic device (100) comprising a keypad (150) having a plurality of keys (152), a first set of indicia (153) associated with the keys and indicating the function of the keys in a first mode of operation, and A second set of indicia (155) associated with the key and indicating the function of the key in the second mode of operation. The orientation of the first set of markings is suitable for viewing in a first direction, and the orientation of the markings of the second set is suitable for viewing in a second orientation different from the first orientation.

Description

Background of the invention [0001] The present invention generally relates to keypads for electronic devices, and more particularly to keypads suitable for use in multiple orientations. [0002] Today, portable electronic devices such as cellular phones, digital cameras, and audio players are becoming increasingly popular. It's not uncommon for some people to have two or more of these devices. But it is inconvenient for the user to carry two or more devices performing different functions. In response to consumer demand, manufacturers have begun to market and sell certain electronic devices that combine in a single component two or more functions normally performed by separate devices. For example, camera phones, which are devices that combine a mobile radio communication device and a data camera in a single unit, are currently offered by many manufacturers. This combined device provides increased user convenience. Also, because combined devices can use the same components ...
