The imaging device 6 is suitable for mounting concealed in an imaging device support. In this illustrated embodiment, the imaging device support comprises the greeting card which is a two leaf card formed from three leaves 3, 4 and 5. The components of the imaging device 6 are fixed to the second central leaf 4 of the card 2, and the third leaf 5 is foldable over onto the central leaf 4 and fixable thereto so that the camera is effectively hidden between the two leafs 5 and 4. The leaf 5 comprises a window for the camera lens 8, as shown (FIG. 3), so that the lens is exposed to the inside of the card when the card is opened. The imaging device is light and compact in form.
The capture of an image by the imaging device is controlled by operation of the activation means 9 and the detection means 10. The activation means is operable on the detection means and is switchable by a user between a non-activated mode, and an activated mode. On adoption of the activated mode, a subsequent detection of the occurrence of a preset event by the detection means 10 effects a corresponding issuance of a trigger signal, the trigger signal causing the capture of the image by the imaging device.
In this case, the activation means 9 is set to the activated mode by removing the safety tab 12 and the detection means is configured to detect the preset event of the card being opened.
The detection means 10 is configured to output a trigger signal upon detection of a preset condition. The detection means 10 may for example, comprise a mechanical trigger, a pressure sensitive pad, or a photosensitive sensor configured to detect when the card has been opened by a change in the light detected.
The activation means 9 may further comprise a timer configurable to start running when the trigger signal is issued. The timer may be settable to delay the image capture for a set period of time for example 10 seconds after it is detected that the card has been opened. The timer may include a number of different time delay settings which may be selected by the sender for example via a small dial within the card.
When the activation means 9 is set to a non activated mode no images are automatically captured even if the detection means detects a preset condition or the trigger is activated.
In addition, the detection means 10 may be configured to detect an alternative preset event or condition. The activation means may alternatively, or in addition comprise other suitable detection means. For example a photosensitive cell, which may detect the event that the card has been removed from an envelope, and issue a trigger signal to the imaging device.
The position of the lens on the card is carefully selected to ensure that the lens 8 will be positioned correctly relative to the card so that an image may be captured as required.
The imaging device may further include a communications interface 13 to enable the images captured and stored thereon to be transferred to another storage device. The communications interface 13 may comprise a USB interface or a wireless communication means such as, a blue tooth or fire wire communication means. An image captured by the imaging device is stored in the data storage means 11 and may be transferred via the communications interface to a computer or other communication device.
