ABSTRACT:
The invention relates to a mobile communications device with a camera, which can be used, in addition to normal mobile telephone and data communications, to take photographs.
From patent document WO 95/00374 it is known a camera integrated into a mobile communications device, wherein the lens of the camera is always exposed like in a normal camera or is brought out from beneath a keypad, being thus protected when the camera is not in use. The lens is released e.g. by moving or lifting the keypad and returned to its place at the same time as the keypad is returned to its place.
A problem with the known devices is that an unprotected lens of a camera integrated into a mobile communications device is susceptible to dirt and scratches or a protected lens is difficult to bring out and return to the storage position.
From the patent document U.S. Pat. No. 5,666,159 it is known an electronic camera system wherein digital photographs taken with the system are wirelessly transmitted to many kinds of remote apparatus.
An object of the invention is to provide an ergonomic mobile communications device with a camera with which photographing is easy and wherein the lens of the camera is protected in such a manner that no special measures are required apart from the normal use of the mobile communications device to bring out the lens.
The objects are achieved using a construction not unlike the sliding cover in modern mobile communications devices, but at the same time dividing the mobile communications device into two roughly equal parts which are slid as far apart as possible before use. Function keys advantageously include at least three and not more than ten keys. Typical function keys include call start and end keys, arrow keys or corresponding browsing keys and memory management keys. Function keys may also include a known multifunction key.
The invention pertains to a mobile communications device with a camera, said device comprising a microphone, loudspeaker, display, keypad proper and a camera, and the mobile communications device comprises at least two parts covering each other alternatively completely in the transport position of the camera or partly in the operational position of the camera so that when the parts cover each other in the transport position of the camera the lens of the camera is protected, and in the operational position of the camera the lens of the camera is exposed. According to the invention an image can be projected through the lens of the camera and the display serves as a viewfinder for the camera by displaying the through the lens projected image to the user of the device and the lens of the camera is placed in the device essentially on a different side than the display.
In accordance with the invention, when the mobile communications device is opened so as to be employed in its proper use, the lens of the camera is brought out from between the parts of the device where it has been well protected from environmental effects such as dust and scratching objects. When in operational state, the mobile communications device can be used for taking photographs preferably by pressing one function key. The display of the mobile communications device serves as a viewfinder when aiming the camera and when the shutter is released, whereafter the image is stored in memory and the picture in the viewfinder is fixed on the display. The mobile communications device is also designed so as to have a shape easy to grip so that when holding the mobile communications device in hand, one would not touch the lens of the camera. Preferred embodiments of the invention are presented in the dependent claims.
