Title: Video environment for camera

Description:
[0001] This application claims priority to U.S. Ser. No. 60/413,178, filed Sep. 24, 2002 and to U.S. Ser. No. 10/358,931, filed on Feb. 5, 2003, which in turn claims priority to U.S. Ser. No. 60/354,595 filed Feb. 5, 2002. 
    
    
     
       FIELD OF THE INVENTION  
       [0002] The present invention relates generally to a video environment in association with a camera for assisting the user in operating the camera, and more particularly to a hosted video environment playing on a touch-sensitive screen of a personal digital assistant (PDA) that is releasably coupled to the camera. The PDA and camera are linked for electronic or data connection therebetween, such that as the user attempts to operate the camera, the camera sends a signal to the PDA to play appropriate video segments to assist the user in successfully operating the camera.  
       BACKGROUND OF THE INVENTION  
       [0003] Digital cameras, for both still and moving images, can be complex to operate, particularly for new or infrequent users. What has been needed is help or instructions about operation of the camera that is easily accessible to the user when the user is operating the camera.  
       [0004] Personal digital assistants are popular items that many people carry with them to gain access to stored information, to download data from the internet and to communicate with others. Further, personal digital assistants include a touch-sensitive screen for controlling the PDA and that screen is typically larger than the view screen on a digital camera.  
       SUMMARY OF THE INVENTION  
       [0005] The present invention combines advantageous features of a touchscreen with a digital camera to yield a convenient system and method by which a camera user can view information about the camera and its use and enter commands for viewing information and operating the camera. Further, the present invention involves a navigable hosted video environment through which a user can control the camera. The hosted video environment provides a personality or character that interacts with or responds to the user&#39;s inputs. In one embodiment, a PDA releasably attaches to the camera and provides a touchscreen for viewing and interacting with the video environment.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENT(S)  
     [0010] As illustrated in FIG. 1, a camera  1  mechanically engages a personal digital assistant  2  in a selectively releasable manner. In one preferred embodiment, the camera  1  includes structure for receiving and attaching to common PDA shapes, such that a user would be able to use his/her favorite PDA in conjunction with a camera  1  according to this invention. Alternatively, the PDA  2  portion of this device  3  is specially adapted to attach to and interact with a camera  1 .  
     [0011] In the preferred, illustrated embodiment of the device  3  in FIG. 1, the PDA attaches to the camera  1  in the horizontal or landscape direction. One advantage achieved in this manner is that the silhouette of the PDA will generally mimic or follow the silhouette of the camera. Further, the landscape orientation of the PDA screen is optimal for text display. The combined unit  3  is relatively compact or easily suited to fitting into typical carrying cases.  
     [0012] The screen  10  on the PDA  2  is used to display images (still or moving) to assist the user in operating the camera. More specifically, a PDA  2  equipped with wireless internet access can access images from a pre-determined web site(s) that relate to operation of the camera. The images may be downloaded or streamed to the PDA  2  and displayed for the user on the PDA&#39;s screen  10 . Alternatively, such images can be stored in memory on the PDA  2  or on a memory chip or card or stick or the like inserted in the PDA  2 . Preferred video or images incorporate navigation cues that allow the user to use the PDA&#39;s touchscreen  10  to navigate through the images to display desired information. In an alternative embodiment, a PDA  2  equipped with speakers and an amplifier, uses sound in lieu of or in addition to images.  
     [0013] In a preferred embodiment, the video or sound content incorporates a host personality. Preferably, the user has the opportunity to select a host personality from a set of predefined personalities. The host personality guides the user through content describing the operation of the camera via pre-recorded video segments.  
     [0014] The camera  1  and PDA  2  are linked electronically for data connection therebetween, such that the camera  1  sends signals to the PDA  2  identifying camera functions that the user is attempting to access. In response, the PDA  2  preferably automatically finds and presents video segments pertaining to the camera function(s) the user is attempting to use. In this manner, the combined camera/PDA performs like an on-board helper to provide the user with the information they need when they need it.  
     [0015] The preferred embodiment described above incorporates a stand-alone PDA which interacts with a camera. This embodiment achieves economies since the user need only own one touchscreen device (rather than paying the additional cost for a second touchscreen on the camera). Nevertheless, a digital camera  10 , depicted in FIGS. 3 and 4, according to the invention is alternatively realized without a stand-alone PDA, by combining a user interface device  15  with an image-capturing apparatus  20 . The user interface device  15  includes a screen  25  to display content or images regarding the control of the image-capturing apparatus  20 . Preferably, the screen  25  is touchsensitive to allow the user to enter commands or input via the screen  25  such that the screen  25  is a user input device  27 . Alternatively, buttons, keys or other user input mechanisms are provided. The camera  10  further includes hardware and software for controlling the image-capturing apparatus  20  in response to the user&#39;s inputs on the display screen  25  or other input mechanism  27 . The content displayed on the touchscreen  25  is preferably navigable video content as described above with respect to the embodiment of FIGS. 1 and 2.  
     [0016] Although an illustrative version of the device is shown, it should be clear that many modifications to the device may be made without departing from the scope of the invention.
