Description

FIELD OF THE INVENTION

[0001] The present invention relates generally to digital cameras and more specifically to user interfaces for digital camera docking systems.

BACKGROUND OF THE INVENTION

[0002] Digital camera users frequently need to recharge the camera, upload images to a personal computer (PC), or print images stored in the camera. These tasks are facilitated by a docking station that serves as both a battery charger and a connection point for other external devices such as televisions, PCs, and printers. One variety of docking station provides a connection between a digital camera and a PC only. A multi-function docking station, on the other hand, may provide connections between the digital camera and multiple external devices. For example, the docking station may be connected to both a television monitor and a PC or printer at the same time. Unfortunately, it is not always clear to the user how to initiate and control an interaction between the digital camera and an external device using the docking station.

[0003] It is thus apparent that there is a need in the art for an improved digital camera docking system user interface method and apparatus.

SUMMARY OF THE INVENTION

[0004] A digital camera docking system user interface method is provided. A digital camera docking system for carrying out the method is also provided.

[0005] Other aspects and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the invention.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Use of a digital camera docking system is facilitated by providing information concerning the operation of the digital camera docking system on the display of the connected digital camera. The docking station may have at least one connection port for external devices. The docking station may automatically detect what external devices, if any, are connected with the docking station. A graphic representing a control element (e.g., a pushbutton) on the docking station may be shown on the display of the digital camera, along with text or other annotation indicating to a user that activating a particular control element will actuate a corresponding control function in the digital camera docking system. Actuating the control function may initiate an interaction between the digital camera and an external device that is connected to the corresponding connection port. Once an interaction such as a TV slideshow, the uploading of images, or the printing of images has been initiated, the digital camera display may provide feedback on the progress of the interaction. These and other aspects of the invention will be described in further detail throughout the remainder of this description.

[0017] FIG. 1 is a block diagram of a digital camera docking system 100 in accordance with an illustrative embodiment of the invention. In FIG. 1, digital camera 105 is connected with docking station 110 via connector 115. Docking station 110 may include connections 120 for at least one external device 125 such as a television monitor, a personal computer (PC), a printer, or any other external device with which digital camera 105 may communicate. In some implementations, at least one of the connections 120 is a Universal System Bus (USB) port. For simplicity, digital camera docking stations do not typically include an internal USB hub, although such an implementation is certainly possible. Throughout this description, “digital camera docking station” refers to the system just described in FIG. 1, including any connected external devices 125.

[0018] FIG. 2 is a functional diagram of digital camera firmware 200 in accordance with an illustrative embodiment of the invention. In FIG. 2, digital camera firmware 200 comprises a set of N control functions 205, one for each connection 120 on docking station 110, and module “Process Docking Station Input” 210. Module “Process Docking Station Input” 210 may process input received from docking station 110 in response to the activation of an input control (“control element”) on the docking station. For example, docking station 110 may, via connector 115, transmit an encoded request to digital camera 105 requesting that a particular control function be actuated. The ith control function 205 may then initiate a task or “interaction” between digital camera 105 and the external device 125 connected with the ith docking station connection 120. Each control function 205 may include the necessary protocols for communication between digital camera 105 and a particular type of external device 125. Although control functions 205 are preferably implemented in firmware 200 of digital camera 105, a different architecture may place control functions 205 in docking station 110. In this case, docking station 110 plays the dominant role in digital camera docking system 100, and digital camera 105 plays a relatively passive role.

[0019] In a typical implementation, docking station 110 includes a microprocessor (not shown in FIG. 1) for carrying out functions such as detecting the presence of connected external devices 125, establishing connections between digital camera 105 and a specified connection 120, and passing requests for control functions 205 to digital camera 105. Once docking station 110 has established a connection between digital camera 105 and an external device 125, the corresponding control function 205 may control the interaction until it is complete.

[0020] FIG. 3A is an illustration of docking station 110 in accordance with an illustrative embodiment of the invention. Shown in FIG. 3A are connector 115 and two control elements 305. Control elements 305 may be, for example, pushbuttons or other suitable input controls. In other implementations, more or fewer than two control elements 305 may be included. For example, a single multi-position control element may actuate control functions 205. In still other embodiments, docking station 110 may have no control elements 305. In the embodiment shown in FIG. 3A, each of the two control elements 305 uniquely corresponds to one of two connections 120 on docking station 110. In this particular illustrative embodiment, one control element 305 corresponds to a TV connection and the other to a USB (e.g., PC or printer) connection. The TV connection facilitates the displaying of images stored in digital camera 105 on a connected television monitor. The USB connection facilitates the uploading of images stored in digital camera 105 to a connected PC or the printing of one or more images on a connected printer.

[0021] FIG. 3B is an illustration of digital camera 105 connected with docking station 110 in accordance with an illustrative embodiment of the invention. Also shown in FIG. 3B is display 310 on digital camera 105. As shown in FIG. 3B, it is advantageous to configure docking station 110 such that digital camera 105 docks with display 310 facing the portion of docking station 110 on which the control elements 305 are found. This enables a user to see display 310 while operating control elements 305.

[0022] FIG. 4A is an illustration of digital camera display 310 containing information regarding the operation of digital camera docking system 100 in accordance with an illustrative embodiment of the invention. In FIG. 4A, display 310 shows a graphic 405 for each detected connected external device 125. Each graphic 405 represents a control element 305 on docking station 110. Activation of the represented control element 305 on docking station 110 actuates the corresponding control function 205. Graphic 405 may suggest the shape and/or color of the represented control element 305. In the example of FIG. 4A, two external devices 125 have been detected. Each graphic 405 may further include pictorial representations of one or more external devices 125 associated with the represented control element 305, as shown in FIG. 4A. Such pictorial representations of external devices may also be advantageously included on the represented control elements 305 themselves. In this particular example, the left graphic 405 in FIG. 4A is associated with uploading images to a PC or printing, and the associated connection 120 may be a USB port. The right graphic 405 in FIG. 4A is associated with the displaying of a slideshow on a television monitor. Each graphic 405 may also be annotated with text 410 explaining how to actuate the control function 205 corresponding to the represented control element 305. Text 410 provides the user with clear and helpful guidance regarding the operation of digital camera docking system 100. In other embodiments, graphic 405 may be omitted, and information regarding the operation of digital camera docking system 100 may be provided using text 410 only.

[0023] FIG. 4B is an illustration of digital camera display 310 containing information regarding the operation of digital camera docking system 100 in accordance with another illustrative embodiment of the invention. In FIG. 4B, each graphic 405 is further annotated with an arrow 415 pointing toward the represented control element 305 on docking station 110. Arrow 415 provides additional assurance to the user that activating a particular control element 305 will actuate the desired control function 205 and that, therefore, the desired interaction will be initiated.

[0024] FIG. 4C is an illustration of a digital camera display 310 containing feedback regarding the progress of an interaction between the digital camera and a printer in accordance with an illustrative embodiment of the invention. Once an interaction has been initiated between digital camera 105 and an external device 125, display 310 may also provide feedback regarding the progress or status of the interaction. In the example of FIG. 4C, an interaction between digital camera 105 and a printer connected to docking station 110 has been initiated. Display 310 may provide feedback 420 indicating that images are being printed. If an error were to occur, display 310 may also provide an appropriate error message to the user.

[0025] Once a transaction such as the printing of images is complete, docking station 110 may optionally remove from display 310 the graphic 405 and annotation associated with the just-completed transaction. For example, if all the images stored in digital camera 105 have been uploaded to a PC, the corresponding graphic 405 may be removed from display 310 to indicate that all images have already been uploaded to the PC. Disconnecting and then reconnecting digital camera 105 and docking station 110, however, may restore all graphics 405 associated with all detected connected external devices 125. In FIG. 4D, one or more images stored in digital camera 105 have just been printed. Accordingly, the graphic 405 associated with the USB connection 120 for uploading and printing (see FIGS. 4A and 4B) has been removed from display 310, leaving only the graphic 405 associated with a TV connection.

[0026] FIG. 4E is an illustration of digital camera display 310 containing instructions for initiating, from a PC connected with docking station 110, an interaction of digital camera 105 and the PC in accordance with another illustrative embodiment of the invention. In this embodiment, docking station 110 includes no control elements 305. Instead display 310 provides instructions for initiating interactions of digital camera 105 with one or more connected external devices 125 from the connected external devices 125 themselves. In the specific example of FIG. 4E, text 425 instructs the user to launch a printing application program on the PC to print images stored in digital camera 105. In this embodiment, the connected external device 125 may send signals over connection 120 to docking station 110, which may in turn pass a request for the interaction (printing images) to digital camera 105 via connector 115.

[0027] FIGS. 5A and 5B are a flowchart of the operation of the digital camera docking system 100 shown in FIG. 1 in accordance with an illustrative embodiment of the invention. At 505 in FIG. 5A, digital camera 105 is connected with docking station 110. Docking station 110, using techniques well known in the art (e.g., detection of voltages or impedances at connections 120), detects which external devices 125, if any, are connected to connections 120 at 510. At 515, digital camera 105 receives from docking station 110, via connector 115, a report of what external devices 125, if any, are connected to connections 120. Digital camera 105 may then display an annotated graphic on display 310 for each detected external device 125. If a control element 305 is activated at 520, control proceeds to 525, where the control function 205 corresponding to the activated control element 305 is actuated in response to a request from docking station 110 via connector 115. The actuation of control function 205 at 525 initiates an interaction between digital camera 105 and the external device 125 that is connected to the corresponding connection 120.

[0028] Once the interaction has been initiated, control proceeds to 530 in FIG. 5B. At 530, the reactivation of the same control element 305 that was activated at 520 may interrupt the current interaction and restore the state of display 310 to that at 515 in FIG. 5A. This allows a user to change his or her mind once an interaction has been initiated. In this case, control returns to 515 in FIG. 5A. If control element 305 is not reactivated at 530, control may proceed to 535 until the interaction is complete. If the control function associated with the just-completed interaction is no longer needed at 540, the associated annotated graphic may be removed from display 310 at 545. If the camera is still docked at 550, control returns to 520 in FIG. 5A. Otherwise, the process terminates at 555.
