       BACKGROUND  
         [0002]    There are times when it is desired to arrange a camera, or other device, such that it always captures images in a specific orientation with respect to an individual, such as, for example, a child or an infant. For example, it may be desired to capture the images as seen by the subject as the subject changes orientations.  
           [0003]    Such orientation can be achieved by mounting the camera on the head or body of the child as is sometime done with sports figures. It is now common place to mount a mini-camera on the helmet (cap, hat, skate, dashboard, puck, baseball, mask, etc) of a sports figure to capture images as seen by such sports figure as the orientation of the sports figure (car, boat, plane, house, ball) changes.  
           [0004]    While cameras have become smaller and smaller, it is not practical to mount such a mini-camera on the head (leg, body) of an infant in order to view from afar (or take pictures of) that which is seen by the infant. It is also difficult to always be able to capture images of a child&#39;s face as the child moves about.  
         SUMMARY  
         [0005]    Embodiments of the teachings of the present invention provide an image recording system comprising a plurality of image capturing devices, a controller circuit for recognizing the orientation of a subject and for determining, based upon the recognition of the orientation of the subject, which one or more of the image capturing devices should be activated at any given time.  
           [0006]    Additionally, embodiments of the teachings of the invention provide an image recording system comprising means for determining the orientation of an object to be recorded and means controlled by the determining means for enabling an image to be taken of the object in a selected orientation of the object.

     DETAILED DESCRIPTION  
       [0009]    The present inventive teachings are directed to a system and method which positions a group of cameras, or other image capturing devices, located away from the subject but arranged such that, by knowing the orientation of the subject at any given time, the proper camera can be activated, thereby capturing the image seen by the subject (or, if desired, the subject&#39;s face, back, side, etc.) based upon the orientation of the subject.  
         [0010]    In one embodiment, sensors on the subject are used to determine orientation of the subject. In another embodiment, the image data from the subject is analyzed and the orientation is determined based upon the analyzed image.  
         [0011]    [0011]FIG. 1 shows one embodiment of a system and method showing the teachings of the invention where there is shown system  10  in which controller device  11  determines the orientation of a subject. Based on that orientation, video images of that subject are provided to capture device  12 , under control of processor  14 . These images could be still images  101 , streaming video  102 , or the like, such as night vision images  103 . The images are communicated via connection  111  to a storage medium, such as a home PC, DVD, or other device (shown here as storage mechanism  13 ).  
         [0012]    Note that connection  110  between controller  11  and capture device  12  could be any suitable link, such as may comprise a wireless or direct connection. Also connection  111  between capture device  12  and storage mechanism  13  could also be any suitable link, such as may comprise a wireless or direct connection. These connections could use  802 . 11  or Blue Tooth Protocols, if desired.  
         [0013]    Connection  103  between controller  11  and a sensor such as sensors  14 - 1 ,  14 - 2 ,  14 - 3  on a subject could be via a wireless transmission device or devices positioned around a subject, such as video capture devices  15 - 1 ,  15 - 2 ,  15 - 3 ,  15 - 4 . These devices could provide still video, streaming video, night vision, or any combination thereof, such as to correspond with the capabilities of capture device  12 . There can be as many device positions in any configuration as desired. The configuration can be circular, square, triangular or any shape or topology.  
         [0014]    According to one embodiment of the invention, it is desired to capture images as the subject would view that image. Thus, the system preferably knows in which direction the user is facing. Knowing that direction, then the proper image capturing device or devices,  15 - 1 ,  15 - 2 ,  15 - 3 , and/or  15 - 4  is turned on under control of controller  11  working in cooperation with processor  14 , to capture the image. Additionally or alternatively, as discussed above, it might be desirable to always take a picture of the facial expression of a subject regardless of the direction that the subject is facing, thereby activating different cameras facing head-on into the subject, as opposed to facing away from the subject.  
         [0015]    Three embodiments of orientation sensors are shown in  14 - 1 ,  14 - 2  and  14 - 3 , each of which uses a different mechanism. Device  14 - 1  utilizes a sticker on a baby&#39;s forehead which transmits, or reflects, a signal to/from device  11 , perhaps via one or more of devices  15 - 1 ,  15 - 2 ,  15 - 3 , and  15 - 4 . Device  14 - 2  is a headband working as discussed for device  14 - 1  and device  14 - 3  is incorporated in a piece of clothing worn by the subject.  
         [0016]    Devices  14 - 1 ,  14 - 2 ,  14 - 3  can be active transmission devices (radio, IR, V, sound, light) wherein these signals are detected by detectors (perhaps built into devices  15 - 1  to  15 - 4 ). Devices  15 - 1  to  15 - 4  could pick up reflected light images (perhaps enhanced, for example, by small mirrors, bezels, discontinuities and the like) of the subject wearing device  14 - 1 , etc. Devices  14 - 1  through  14 - 3 , could have particular shapes and/or sizes which can easily be compared to a known standard (shape, color, temperature, light spectrum, etc.) in any one of several well-known ways. The devices shown are for illustrative purposes only and any type of device could be used.  
         [0017]    Also, if the subject assumes an unnatural position, as determined, for example, by comparison to a set of known “natural” positions as contained, for example, in controller  11 , or a data base (not shown) associated with controller  11 . This system can be programmed to provide a warning if an unnatural position is determined. The system could, if desired, provide indications of position changes by keeping track of the last known positions in a data base.  
         [0018]    Processor  14  assists in the processing of the signal information and coordinates the sending and receiving of the wireless communication over links  103  and  110 . Controller  11  can also communicate over link  110  to devices  12  or  13 . Processor  14  could also operate to capture the image from the various video capture devices and to search that image for data that matches what is desired. For example, if it is desired to always view a facial expression of a child, the software in processor  14  (or in a data base, not shown) could be designed to look for facial characteristics in a captured image that come closest to matching prior/predefined facial attributes.  
         [0019]    Once controller  11  determines which camera to use, that camera is activated, either continuously or periodically, and the images are transmitted to capture device  12  for processing, by a processor in device  12  or by processor  14 . This processing could be, for example, digital imaging, which could include sizing, cropping, etc. The processed imaged are sent to storage device  13 .  
         [0020]    [0020]FIG. 2 is a flow chart  20  showing the operation of the embodiment of FIG. 1 where determination is made via process  202  that it is time to obtain an image. If the answer is no, then nothing is done until a next determination as to whether it is time to obtain images. If the answer is yes, then the orientation is checked as shown in process  203 . Note that in some situations, the images are to be generated continuously and, therefore, different cameras may be selected as the subject&#39;s orientation changes. In this situation, the orientation may continuously be checked via process  203  without a determination as to a time to obtain images as described above with respect to process  202 .  
         [0021]    After the orientation is checked, the information, with respect to orientation, may be processed at process  204 . This processing was discussed above using signals transmitted from (or to) the body of the subject. Also as discussed, processing can be done to determine the orientation of the subject from the actual captured images. In any event, process  205  turns on the appropriate camera, as may be determined from processing information with respect to orientation, and sends the images for processing and/or storage via process  206 . A determination via process  208  is made as to whether the image should be stored or discarded. If discarded, the images are controlled by process  207 . If stored, they are controlled by process  209 .  
         [0022]    After the appropriate camera is turned on, process  210  determines whether the orientation has changed. If it has not, then the same camera is maintained via process  211 . A determination is then made, via process  212 , as to whether the time for capturing images has expired. If time has expired, then the camera is turned off via process  213 . If, however, the time for capturing images has not expired, then nothing is done (process  214 ) to change the operation until a next determination that the orientation has changed (process  210 ) and/or that the time for capturing images has expired (process  212 ). Following processes  213  or  214  the system restarts via process  202 .  
         [0023]    If the orientation has changed, as determined by process  210 , then the cycle repeats via process  203 .
