The present invention generally concerns systems and methods for controlling an electronic device (e.g., a camera, a camcorder, a navigation unit, a gaming machine and a digital picture frame). The systems generally employ a removable and programmable active processing module configured for enabling an electronic device to act in a customized manner, i.e., perform a primary function using at least one custom operating parameter or perform a secondary function different from its primary function. For example, the active processing module can be programmed to control operations of a digital camera such that it performs one or more secondary functions (e.g., a travel guide function, a navigation function, a gaming function, a learning guide function, an assistant function, an electronic book viewer function, a media player function and/or a wireless connection function).
Notably, the active processing module provides an affordable way to add additional applications to the electronic device without jeopardizing the competitiveness of the selling price position of the electronic device. The active processing module also provides an affordable way to add additional applications to the electronic device without affecting the quality level of the electronic device.

The camera 100 is generally configured to perform a primary function (i.e., to record images as still photographs) that is intended by a designer and/or a manufacturer thereof. However, the camera 100 is also configured to operate in a customized manner. In this regard, the camera 100 can be customized to perform secondary functions and/or its primary function using customized parameter values. The secondary functions are functions different than the primary functions of the camera 100 that were intended by the designer and/or manufacturer thereof. For example, the camera 100 can be customized to operate as a digital travel guide, a navigation unit, a gaming machine, a digital learning guide, a digital cooking assistant, a digital cooking guide, an electronic book viewer, a digital phone book and/or a personal digital calendar. Embodiments of the present invention are not limited in this regard. For example, if the electronic device is a camcorder or a gaming machine (instead of a camera), then the electronic device can further be customized to operate as a digital media player.

The buttons 204, . . . , 216 are used to signal various logical selections of options and commands based on the content of the display device 202.
A communication interface 314 is provided on a side panel 350 of the camera 100. The communication interface 314 can include, but is not limited to a Universal Serial Bus (USB) interface. The communication interface 314 facilitates the coupling of the camera 100 to a computing device (not shown in

An actuation mechanism 320 is provided for ejecting the removable memory module 312 from the insert space 310. After removing the removable memory module 312 from the camera 100, the user can connect the removable memory module 312 to the computing device (not shown in
As noted above, the camera 100 is configured to operate in a customized manner. The customizability of the camera 100 is facilitated by a removable-programmable active processing module 308. The active processing module 308 can be a plug-and-play card. An exemplary embodiment of the active processing module 308 will be described in detail below in relation to
As shown in

As shown in
The imaging device 402 can include, but is not limited to, the lens 110, a filter 404, an image sensor 406, motors 408, an analog signal processor 410, a timing generator 412, an Analog to Digital Converter (ADC) 414 and an interface 418. Each of these components 110, 404, . . . , 418 is known to persons having ordinary skill in the art, and thus will not be described herein.
The computing device 418 includes the removable memory module 312, the communication interface 314, the active processing module 308, the display screen 202 and the input device 250. As noted above, the camera 100 can be coupled to an external computing device through the communication interface 314. The communication interface 314 can send information (e.g., still image information) between the camera 100 and external computing device (not shown in
The CPU 424 performs actions involving access to and use of memory 420, 312. Memory 420 includes volatile and/or non-volatile memory. For example, the memory 420 can include, but is not limited to, Random Access Memory (RAM), Dynamic Random Access Memory (DRAM), Static Random Access Memory (SRAM), Read Only Memory (ROM), flash memory, a disk driver and/or other forms of program bulk-storage. One or more device-control applications are stored in memory 420 and executed by the CPU 424. The device-control applications are generally operative to control operations of the camera 100 such that it performs its primary function using original operating parameter values (e.g., captures still images of objects).
In this regard, the CPU 424 performs actions for controlling the operations of the camera 100 in accordance with a user input. The user input is facilitated by the on/off switch 106, the button 104, the display screen 202 and the input device 250. The input device 250 includes, but is not limited to, buttons 204, . . . , 216. The buttons 204, . . . , 216 are configured to remain in a rest position until pressed, whereupon the buttons are placed in their actuated positions until the pressing force is removed. Pressing a button 204, . . . , 216 causes an electrical signal to be communicated to the CPU 424. In response to the reception of the electrical signal, the CPU 424 controls the operations of the camera 100.
The operations of the camera 100 can also be controlled by the active processing module 308. In this regard, the circuit 400 includes a module interface 428. When the active processing module 308 is inserted into the camera 100, the CPU 424 can be inhibited from controlling operations of the camera 100. In this scenario, the active processing module 308 acts as a new master of the camera 100 in addition to the CPU 424. Embodiments of the present invention are not limited in this regard. For example, the operations of the camera 100 can be controlled by the active processing module 308 working in conjunction with the CPU 424.
Notably, the active processing module 308 can be programmed by a user using a computer workstation, a desktop personal computer system, a laptop personal computer system, or any other general purpose computer processing device. This programming can generally involve defining customized values for operating parameters of the camera 100. For example, a user can set a shutter or exposure time to a desired duration for a particular application. The user can also develop and/or store a device-control application on the active processing module 308. In this scenario, the device-control application can be operative to cause the camera 100 to perform a secondary function other than its intended primary function. The device-control application can also be operative to cause the camera 100 to perform its primary function using customized values for one or more operating parameters.
