FIELD OF THE INVENTION
The present invention relates to electronic devices and, more particularly, to electronic devices and methods for displaying images.
BACKGROUND OF THE INVENTION
Mobile electronic devices, such as wireless communication terminals (e.g., cellular telephones), are widely used to store and display digital image files (e.g., data files representing still images such as digital photographs or pictures). A user may wish to share picture files stored on his own mobile electronic device with one or more other people nearby. One way to do this is to display the images on the user's own mobile electronic device for the others to view. However, this approach may not be feasible or convenient. If the other people have mobile electronic devices of their own, the user may send his picture files to the other mobile electronic devices one-by-one using multimedia messaging service (MMS) or a point-to-point interface (e.g., a Bluetooth or infrared (IR) interface), for example. The user may also display the pictures on another device such as a media center (e.g., a PC or laptop, a television, an audio receiver, etc.), if available. The media center may be equipped with a suitable communication module, which may be an integrated module or an auxiliary (e.g., plug-in) module to allow communication across a point-to-point interface (e.g., a Bluetooth or infrared (IR) interface).

According to some embodiments, the wireless communication module is configured to communicate with other communication terminals over a direct point-to-point wireless interface and the controller is configured to establish the slideshow session with the at least one participant wireless communication terminal and to send the series of digital image files to the at least one participant wireless communication terminal during the slideshow session via the direct point-to-point wireless interface. According to some embodiments, the direct point-to-point interface is a Bluetooth wireless RF connection.
Methods according to embodiments of the present invention may include a combination of the methods of described with reference to FIGS. 2 and 3. Further aspects and embodiments of methods in accordance with the present invention will be apparent from the following descriptions of further embodiments.
With reference to FIG. 4, a slideshow display system 100 according to embodiments of the present invention is shown therein. The system 100 includes the mobile wireless communication terminal 10A (also referred to herein as the “host wireless communication terminal” or “host terminal”) and a plurality of additional participant wireless communication terminals 10B, 10C, and 10D (also referred to herein as the “participant wireless communication terminals” or “participant terminals”).
The terminals 10B-D may be configured as described above with regard to the terminal 10A. The terminals 10B-D each include a wireless communication module 32 and an image management module 40. However, the respective image management modules may be differently configured for each terminal 10A-D depending on the intended functionality of the device. According to some embodiments, all or some of the terminals 10B-D are mobile wireless communication terminals. According to some embodiments, all or some of the terminals 10A-D are handheld mobile wireless communication terminals.
The system 100 will now be described using an illustrative example of use. A group of users at a gathering each have a respective one of the terminals 10A-D. Various image files are stored on the host terminal 10A. The host may wish to share some or all of the image files stored on his mobile terminal 10A with the other users at the gathering. Displaying the images on the host's own mobile terminal 10A for viewing by the other users may be cumbersome or infeasible. A properly equipped media center may be unavailable, unsuitable and/or undesirable for use. With known and available technology, the image files can be sent file-by-file and participant-by-participant to the participants' own terminals 10B-D using a wireless interface (e.g., via MMS, Bluetooth, etc.). Each participant can then view the image files on his or her own display. While this approach may be preferable to the other conventionally available options, it may require a substantial amount of work by the host and may be time-consuming and inconvenient. This approach may also be inconvenient for the participants, who typically must actively interact with their mobile terminal (e.g., toggle through the images files) to accept, access and view the image files.
In accordance with embodiments of the present invention, the foregoing shortcomings can be overcome by establishing a slideshow session and executing a slideshow using the host terminal 10A. Typically, each terminal 10A-D will have the appropriate image management module 40 (e.g., software or firmware application) installed thereon. The respective image management modules 40 and controllers 30 of the host and participant terminals may cooperate to provide the communication, display, connection and other functionality and operations described herein.
To initiate the slideshow procedure, the host instructs the controller 30 of the host terminal 10A to invoke the slideshow function. For example, the slideshow procedure may be initiated by selecting a “GROUP SLIDESHOW” function or the like from a menu of the host terminal 10A. The function may be provided as an option in a menu in a picture view mode of the host terminal 10A.
The controller 30 of the host terminal 10A establishes a wireless connection (i.e., communicatively couples) with each of the participant terminals 10B-D. According to some embodiments, the wireless connection is a direct point-to-point wireless communication interface connection, according to some embodiments, a direct point-to-point RF connection and, according to some embodiments, a Bluetooth connection. The connections may be established in a known manner. For example, in the case of Bluetooth connections, the participant (slave) terminals 10B-D may be set to a searchable/discoverable state and the host (master) terminal 10A emits an inquiry to identify the available participant (slave) terminals 10B-D to form a piconet or personal area network.
As illustrated, the host terminal 10A communicates with the participant terminals 10B, 10C and 10D via direct point-to-point wireless interfaces or links 112, 114 and 116, respectively. According to some embodiments, the host terminal 10A may communicate with a further participant terminal via wireless interfaces or links through a WLAN router. According to some contemplated embodiments, all of the signals provided between the host terminal 10A and the participant terminals 10B-D to execute the slideshow procedure are provided via direct point-to-point wireless interfaces. According to some contemplated embodiments, all of the signals provided between the host terminal 10A and the participant terminals to execute the slideshow procedure are provided via direct wireless radio frequency (RF) interfaces such as Bluetooth interfaces.
Before or after establishing the connections, the host terminal 10A may allow the host to identify and designate valid participant terminals by any suitable method. The host terminal 10A may be used to define specific, predefined groups such as a group of the potential participant terminals that will be permitted to participate and/or a group of the potential participant terminals that may be invited to join the participant group. One or more predefined groups may be stored on the host terminal 10A in the memory 34 for subsequent retrieval and use.
The host terminal 10A then sends an invitation signal to each of the participant terminals 10B-D. For example, the invitation signal may cause the receiving participant terminals 10B-D to display to the respective end users an inquiry such as “TOMAS K750 WOULD LIKE TO RUN A SLIDESHOW ON YOUR PHONE. DO YOU ACCEPT?” Each potential participant may then operate his or her participant terminal 10B-D to reply to the host terminal 10A with an acceptance signal. For example, the participant terminals 10B-D may provide “YES” and “NO” soft keys for responding. The controller 30 of the host terminal 10A then adds the accepting participant terminals to a slideshow distribution group list.
The host may selectively control which of the available participant terminals receive the aforementioned invitation signals. The host terminal 10A may provide suitable menu options (e.g., in the form of soft keys) such as “CHOOSE GROUP” and “SEARCH FOR PHONES”.
If the “CHOOSE GROUP” option is selected, the host terminal 10A allows the host to select from one or more predefined groups of participant terminals, the members of which will thereafter receive an invitation signal and may join the slideshow distribution group by replying as discussed above.
According to some embodiments, if the “SEARCH FOR PHONES” option is selected, the host terminal 10A will scan the area to identify the available potential participant terminals (e.g., those within operational range of the host terminal's Bluetooth signal). The controller 30 will generate a list of the available potential participants. The host may select (e.g., using check boxes) the potential participant terminals to which an invitation signal will be sent. The potential participant terminals may then opt in by replying with an acceptance signal to accept the invitation and join the slideshow distribution group.
In the foregoing manner, the participant slideshow distribution group is set and connections are established between the host terminal 10A and each of the participant terminals in the participant slideshow distribution group (as illustrated, the participant terminals 10B-D). Once the connections are established between the host terminal 10A and the participant terminals 10B-D, the host can establish and execute a slideshow session. During the slideshow session, the host terminal 10A sends image files to the participant terminals 10B-D of the slideshow distribution group, and the receiving participant terminals 10B-D display these image files on their respective display screens.
The host terminal 10A may provide the host with an interface that allows the host to preview images before sending them and to selectively withhold image files from the slideshow as desired. By way of illustration, the image management module 40 provides a user interface display on the host terminal 10A such as a display 150 as shown in FIG. 5, which is merely exemplary. In the illustrated embodiment, the display 150 includes image thumbnails 152, control buttons 154, and a participant listing 156 (under the heading “AUDIENCE”). The host can then select the thumbnail 152 corresponding to each image the host wishes to include in the slideshow. After a thumbnail is selected, the host hits the “SHARE” button to send the image to the participant terminals 10B-D. Alternatively, the image management module 40 may enable the host to select multiple thumbnails for the slideshow before sending the corresponding image files to the participants. The host may be enabled to send a pre-existing group or set of image files. The image management module 40 may allow the host to edit or modify the group of images (e.g., delete selected images) before distributing.
Other techniques may be employed to enable selection of the slideshow images. For example, the image management module 40 may list available image files by name and allow the host to select (e.g., using check boxes) the image files for the slideshow. The image management module 40 may display each image file in turn and allow the host to either skip the image file or send it as part of the slideshow.
Various other ways of structuring the slideshow will be apparent to those of skill in the art upon reading the description herein. In addition to determining the image files to be included in the slideshow, the image management module 40 may enable the user to select other parameters such as image resolution, image display time, transition time between display of images, transition type (e.g., immediate replacement, fade in, fade out, intervening blackout, etc.), image background, etc. It will be appreciated that more, less and/or different information may be provided in the display 150 as well.
The slideshow may be automated such that image after image is distributed without requiring the host to individually command the controller 30 to send each image file. Alternatively, the image files may be distributed one at a time responsive to respective send commands from the host to the host terminal 10A. In either case, the host actuates a send or share command to the controller 30 of the host terminal 10A, responsive to which the controller 30 of the host terminal 10A then sends a digital image file to each of the participant terminals 10B-D as a group. That is, the controller 30 executes the send command by sending the image file to each member of the slideshow distribution group so that the host is not required to send the image file to each participant terminal individually (i.e., by separately activating a send command for each participant terminal). Responsive to the send command or commands, the image files may be sent to the distribution group in series or succession for serial display as a slideshow.
Each distributed image file may be stored on the participant terminal for display. Alternatively, the image file may be streamed to the participant terminal. According to some embodiments, the image file, whether streamed or stored in whole, will be automatically erased (i.e., without user intervention) from the host terminal 10A after display during the slideshow. According to some embodiments, the digital image files are sent from the host terminal 10A to the participant terminals 10B-D serially and in temporally spaced apart sequence so that the number of such image files stored on each participant terminal can be limited. According to some embodiments, each such image file is automatically erased during and/or before receipt of the next image file.
According to some embodiments, the host terminal 10A pre-selects or identifies a specified set of image files to be included in the slideshow. For example, the set may be comprised of “pictures taken in May 2004”, from a specified “share folder”, or the like. When the slideshow session is initiated, the first image file is sent to the participant terminals 10B-D as described herein and the other image files of the specified set are also sent wirelessly to the participant terminals 10B-D “in the background”. These other image files are stored locally on the participant terminals 10B-D to await subsequent display thereon. According to some embodiments, the host terminal 10A sends the subsequent image files while the first image file is being displayed. For example, the latter nine of a set of ten image files may be wirelessly sent to and stored on the participant terminals 10B-D while the first image of the set is being displayed. When it is time to view a stored image file, the controller 30 of the host terminal 10A sends a signal to each participant terminal 10B-D to display the stored image file. According to some embodiments, the host terminal 10A sends a short command or pointer to the participant terminals 10B-D instructing or causing the participant terminals 10B-D to display the chosen image file (e.g., “show pic DSC0232”) instead of sending the image file itself. Such embodiments may have the advantage that it is not necessary to wait for each image file (which may be relatively large) to be sent to and loaded onto the participant terminals 10B-D after display of the previous image file. This may serve to speed up the slideshow and minimize delay or the impression of delay. According to some embodiments, the stored files are temporarily stored on the participant terminals 10B-D and may be automatically erased after display.
The controller 30 of the host terminal 10A may execute the foregoing steps for each image file in turn and automatically (i.e., without user intervention).
According to some embodiments, responsive to the image send command from the host, each image file is sent to the participant terminals 10B-D such that it is displayed simultaneously on the displays of each of the plurality of participant terminals 10B-D. In this way, the images can be simultaneously viewed by the participants as if they were viewing the same display. According to some embodiments, each image file is sent to the participant terminals 10B-D such that it is first displayed on each participant terminal substantially simultaneously (i.e., such that any delay in initiation of display of the image file as between participant terminals is not readily perceptible to the end users). According to some embodiments, responsive to the send command, the data signal(s) or packet(s) embodying the image file are sent by the host terminal to the participant terminals substantially simultaneously. In this case, a shared signal may be issued by the host terminal and received by multiple participant terminals. Alternatively, separate signals may be issued to respective ones of the participant terminals simultaneously or without deliberate delays between issuance of the separate signals. According to some embodiments, the time period between issuance of each such separate signal and the next does not exceed one second.
According to some embodiments, during the slideshow session, the image files are “pushed” by the host terminal 10A onto the participant terminals 10B-D. Once the slideshow session has been established, the image files received by the participant terminals from the host terminal 10A are automatically displayed by the participant terminals without requiring further action by the participant. That is, once a participant terminal 10B-D has accepted the invitation to join the slideshow, the images are displayed in series without requiring the participant to accept each image file from the host terminal 10A. According to some embodiments, each image file is sent to the participant terminals such that the image file is automatically simultaneously displayed on each participant terminal. According to some embodiments, each image file is sent to the participant terminals such that the image file is automatically first displayed (i.e., the display is automatically initiated) on each participant terminal substantially simultaneously.
As the host terminal 10A runs through the image files in this fashion, the host may modify the not yet shown portion of the slideshow as desired. According to some embodiments, new participant terminals can join the group and receive the slideshow as the host terminal 10A runs through the slideshow.
The digital image files sent by the host terminal 10A to the participant terminals 10B-D may be any suitable image files. According to some embodiments, the distributed image files are copies of image files stored in the memory (e.g., the memory 34) of the host terminal 10A. The image files may be digital picture files. The image files may be copies of picture files acquired using the camera device 36.
The system 100 can provide a convenient and enjoyable system for displaying image files to others, particularly in a slideshow format. The system 100 can also allow the host terminal to create, coordinate, control and/or manage the slideshow.
While slideshows including a series of image files are discussed above, according to some embodiments, a slideshow may include only a single image file.
While the system 100 as described includes a plurality of participant terminals, according to other embodiments only a single participant terminal is included in the slideshow distribution group. In particular, according to some embodiments, a slideshow session is established between the host terminal 10A and the participant terminal, a series of digital image files are sent from the host terminal 10A to the participant terminal during the slideshow session, and the image files are pushed onto and automatically displayed on the participant terminal during the slideshow session without requiring further input such as image-by-image acceptance from the participant terminal. For example, the acceptance of an invitation to join a slideshow may be the only response required of the participant terminal in order to view a multi-image, serial slide show.
As will be appreciated from the foregoing description, all or some of the direct point-to-point wireless interface connections between the host terminal 10A and the participant terminals 10B-D may be direct point-to-multiple point wireless interface connections. The signals sent by the host terminal 10A to the participant terminals 10B-D may be sent via direct point-to-multiple point wireless interface connections.
According to some embodiments, the signals are broadcast by the host terminal 10A to the participant terminals 10B-D. For example, the image files may be broadcast by the host terminal 10A to the participant terminals 10B-D to effect a slideshow as described herein.
The application programs described herein, including the image management module 40, are illustrative of programs that implement various features according to embodiments of the present invention. It will be appreciated that other and/or additional application programs may be employed in accordance with embodiments of the present invention.
Although FIG. 1 illustrates an exemplary hardware/software architecture that may be used in mobile terminals and/or other electronic devices for providing a slideshow, it will be understood that the present invention is not limited to such a configuration but is intended to encompass any configuration capable of carrying out operations described herein. For example, although the memory 34 is illustrated as separate from the controller 30, the memory 34 or portions thereof may be considered as a part of the controller 30.
