     In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of some embodiments. However, it will be understood by persons of ordinary skill in the art that some embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, units and/or circuits have not been described in detail so as not to obscure the discussion. 
     The term “side-camera” or “side-panel camera” as used herein may include, for example, a camera other than (a) front-side (front-facing) camera, and also other than (b) back-side (back-facing) camera. The term “side-camera” or “side-panel camera” as used herein may include, for example, a non-front non-back camera, or a non-front-facing and non-rear-facing camera; or a camera facing (or aiming) towards a right-side or left-side or top-side or bottom-side relative to the electronic device that the camera is embedded in; or a camera located on, or within, or at, or on top of, or integrated in, or embedded in, a side-panel. 
     The term “side-panel” as used herein may include, for example, any side other than the front side (which has the screen or the touch-screen) and other than the back side (or the rear side, or the side that is generally opposite to the touch-screen, or the side that is generally parallel to the touch-screen); or a right-side panel, or a left-side panel, or a top-side panel, or a bottom-side panel; or a right-side face, or a left-side face, or a top-side face, or a bottom-side face. 
     Reference is made to  FIGS. 1A ,  1 B and  1 C, which are schematic illustrations of an electronic device  100  in accordance with some demonstrative embodiments of the invention. Electronic device  100  may be, for example, a mobile computing device, a portable or mobile device, a smartphone, a tablet, a mini-tablet, a “phablet” (phone-tablet device), a portable gaming device, a portable audio/video player, or the like. 
       FIG. 1A  shows device  100  from a first perspective, showing particularly its front-side face and its touch-screen; while  FIG. 1B  shows device  100  from a second perspective, showing particularly its back-side face; while  FIG. 1C  shows device  100  from a third perspective, in which device  100  stands “upside down” (or, stands “on its head”) and showing its front-side face. 
     Electronic device  100  may be generally box-shaped, or may be generally a rectangular cuboid, or may be generally a prism, or may have six faces or six panels, or may have six generally-rectangular faces or six generally-rectangular panels. In some embodiments, a face or panel that is rectangular or generally rectangular, may have rounded corners, or may have smooth or curved corners, or may have slanted or diagonal corners; and may be symmetrical or non-symmetrical. 
     In some embodiments, device  100  may be a rectangular prism or a cuboid having sharp corners or sharp edges or sharp panels. In other embodiments or implementations, device  100  may have rounded or smooth or slanted or non-sharp corners or edges or panels or faces. In some embodiments, for example, device  100  may be an octagonal prism, and a cross-section of device  100  may be an octagon, particularly an octagon formed by taking an elongated rectangle and replacing each 90-degree corner with a small 45-degree slanting diagonal line. 
     In some embodiments, device  100  may be wedge-shaped, or may have a “bump” or a diagonal bump in its rear side, in order to contain or store or accommodate a battery or a power cell; and the drawings may not necessarily show such possible bump or wedge, or other possible non-flat surface or non-flat region. 
     Electronic device  100  may have a front-side face  101 , which may comprise a screen  141  embedded therein or integrated thereon. Screen  141  may be able to display graphics, texts, images and/or videos; and may optionally be a touch-screen or a multi-touch-screen, able to receive tactile input, user input, input provided by finger gestures, input provided by stylus gestures, or the like. Optionally, front-side face  101  may further include a front-facing camera  151 , or may include an aperture or orifice for such front-facing camera  151 . 
     Electronic device  100  may have a rear-side face  102 , which may optionally include a rear-side camera  152  or an aperture or orifice for such rear-facing camera  152 . 
     Electronic device  100  may further include a top-side face  103 , a bottom-side face  104 , a right-side face  105 , and a left-side face  106 . 
     Front-side face  101  may be generally parallel to rear-side face  102 . Front-side face  101  may be generally perpendicular to faces  103 - 106 . 
     Rear-side face  102  may be generally parallel to front-side face  101 . Rear-side face  102  may be generally perpendicular to faces  103 - 106 . 
     Top-side face  103  may be generally parallel to bottom-side face  104 . Top-side face  103  may be generally perpendicular to front-side face  101 , to rear-side face  102 , to right-side face  105 , and to left-side face  106 . 
     One or more of faces  101 - 106  may include one or more optional components, for example, a volume button or slider or controller, an earphone socket, a USB or mini-USB or micro-USB port, an HDMI port or mini-HDMI port or micro-HDMI port, or the like. USB stands for Universal Serial Bus. HDMI stands for High-Definition Multimedia Interface. In a demonstrative example, left-side face  106  may include a micro-USB port  188 , and a mini-HDMI port  189 . In a demonstrative example, right-side panel  105  may include a volume controller  195 , a power button  196 , and an audio output port  187  (e.g., a female socket able to accommodate a male audio jack, a 3.5 millimeter audio jack, a 2.5 millimeter audio jack, or the like). 
     Top-side face  103  may include a camera  153  able to capture or acquire images and/or videos; for example, comprising a High-Definition (HD) camera or 720p camera, a Full-HD camera of 1080p camera, a CMOS (Complementary Metal-Oxide-Semiconductor) imager or camera, an Active-Pixel Sensor (APS) imager or camera, a CCD (Charge-Coupled Device) imager or camera, or the like. Camera  153  may be referred to herein, also, as a thin-side camera, a thin-face camera, a thin-panel camera, a top-side camera, a top-panel camera, or a top-face camera. 
     Camera  153  may be embedded within, or integrated in, or embedded through the top-side face  103 ; or may sense or acquire or capture images or videos through the top-side face  103 . 
     Camera  153  may be aimed, or may image, acquire or capture a field-of-view, or an area or region or an object, which may be generally perpendicular to the direction that front-side camera  151  is facing or is acquiring or is capturing. 
     Camera  153  may be aimed, or may image, acquire or capture a field-of-view, or an area or region or an object, which may be generally perpendicular to the direction that rear-side camera  152  is facing or is acquiring or is capturing. 
     Camera  153  may be aimed, or may image, acquire or capture a field-of-view, or an area or region or an object, which may be: generally parallel to the longest dimension (or the longest edge) of electronic device  100 , or generally parallel to the longest dimension (or the longest edge) of front-side face  101 , or generally parallel to the longest dimension (or the longest edge) of screen  141 . 
     When utilizing a conventional smartphone having a rear-side camera, a first user Adam may stand 1.5 meters away (or four feet or five feet away) from a second user Bob, and may wish to capture an image of the face of Bob (or, the upper one-half of the body of Bob, or the upper one-third of the body of Bob). Accordingly, Adam may position the smartphone at the eye-level of Adam, approximately 25 centimeters in front of Adam&#39;s eyes, perpendicularly to the ground, and generally parallel to the vertically-standing body of Bob (and to the vertically-standing body of Adam himself). This may be uncomfortable; may require Adam to lift the conventional smartphone towards Adam&#39;s eye-level; may require positioning the smartphone directly between the eye-level of Adam and the object-of-interest (e.g., the face of Bob), thereby hiding or obscuring from Adam&#39;s view at least some of the object that Adam is attempting to photograph. Additionally, this unique positioning of the smartphone makes it immediately apparent to Bob that Adam is attempting to capture an image (or a video) of Bob, which may not necessarily be desired by Adam (e.g., if Adam desires to acquire image(s) or video(s) of the face of Bob without necessarily letting Bob be aware of this). Additionally, holding the conventional smartphone upright and vertical, perpendicularly to the ground, at eye-level, may be uncomfortable for the user Adam, and may require the user Adam to twist his hand that holds the smartphone (e.g., the thumb pointing upwardly towards the sky or the ceiling; the other four fingers wrapped or stretched around the smartphone and curling back towards Adam&#39;s body). 
     In contrast, in accordance with some demonstrative embodiments, a user Carl may utilize electronic device  100  (e.g., a smartphone or a tablet) to capture image(s) or video(s) of a user David, without having to assume the particular position described above. The user Carl may hold the electronic device  100  at the level of Carl&#39;s waist or tummy or heart, and not at the level of Carl&#39;s eyes or Carl&#39;s head or David&#39;s face. The user Carl may hold the electronic device at a slanted angel, for example, approximately 30 or 35 or 40 or 45 or 50 or 55 or 60 degrees relative to the ground, “aiming” or directing the top-side camera  153  at an angel towards the desired object-of-interest (e.g., the head of David). In some embodiments, David may not necessarily notice that Carl is attempting to acquire (or is acquiring) images or videos of David, since the electronic device  100  may not be held conspicuously in front of David&#39;s face, and may not be positioned conspicuously at the eye-level or the head-level of David and/or Carl. This may optionally allow Carl to acquire images and/or videos of David in a convert or secret manner, without necessarily drawing the attention of David to the imaging process. This may allow, for example, acquisition of a more naturally-looking image or video, or acquisition of an image or video of David (or other person or object) in a more “natural” or non-tampered or non-staged situation, thereby optionally providing more realistic (or “naturally looking”) images or videos, or less “staged” images or videos in which the acquired object may be aware of the imaging process and may act (e.g., intentionally) upon such awareness. 
     In some embodiments, electronic device  100  may be implemented by using a housing  110  which may enclose therein some or all of the hardware components which may be included in electronic device  100 , for example, a processor, a memory unit, a storage unit, a SIM card, or the like. Such housing  110  may be generally box-shaped, or may be a generally rectangular cuboid, or may have one or more rounded or curved or smooth corners. Optionally, housing  110  may include an aperture  111  or other suitable orifice or opening or hole, which may be located at the top-side face of housing  110 , and which may allow a camera (e.g., located within the housing  110 ) to acquire images or videos there-through. 
     Top-side camera  153  may be associated with, or may be controlled by or operated by, a camera application which may run on the electronic device, and which may allow a user to initiate capturing of image(s) and/or video(s), for example, by pressing an on-screen button, by uttering a speech utterance or other sound which may be recognized (e.g., using a speech recognition module or a speech-to-text module), or by other means of providing user input or user command. In response to such command or input, top-side camera  153  may acquire image(s) and/or video(s), and data representing such acquired image(s) or video(s) may be stored in a local memory unit or a local storage unit, or may be transferred or transmitted (e.g., over a wireless communication link, or over the Internet) to a remote repository, to a remote server, to a remote storage device, to a remote “cloud computing” server, or the like. 
     In some embodiments, top-side camera  153  may be located at (or near) the center of the top-side face  103 ; or may be located in the central one-third portion of the top-side face  103 . 
     In some embodiments, top-side camera  153  may be located in the rightmost one-third region of the top-side face  103 ; or in the rightmost one-quarter region of the top-side face  103 . 
     In some embodiments, top-side camera  153  may be located in the leftmost one-third region of the top-side face  103 ; or in the leftmost one-quarter region of the top-side face  103 . 
     Optionally, top-side camera  153  may be associated with, or coupled to, an illumination unit  183  which may be located on or at top-panel  103 , in proximity to top-side camera  153 . Optionally, front-side camera  151  may be associated with, or coupled to, an illumination unit  181 , which may be located on or at front-panel  101 , in proximity to front-side camera  151 . Optionally, back-side camera  152  may be associated with, or coupled to, an illumination unit  182 , which may be located on or at back-panel  102 , in proximity to back-side camera  152 . 
     Each one of illumination units  181 - 183  may be or may include, for example, a unit able to produce a flash or artificial white in order to illuminate (or to help illuminate) a scene; and may utilize or may include, for example, xenon flash, LED-based flash, or other illumination technique or illumination means. 
     Each one of cameras  151 - 153  may be associated with, or coupled to, or connected to, circuitry and/or wires which may connect to other components of device  100 ; thereby enabling each one of cameras  151 - 153 , for example, to receive an incoming command to capture an image or a video; to respond to such command by acquiring an image and by transferring image data (e.g., raw or compressed or encoded) to a memory unit or a processor; to acquire video and transfer video data (e.g., raw or compressed or encoded) to a memory unit or a processor; to configure settings of the camera, for example, brightness level, contrast level, special effects (e.g., black-and-white or greyscale effect, polarized effect, negative image effect), illumination settings (e.g., turn illumination unit off; force illumination unit to illuminate; operate the illumination unit automatically if it is determined that ambient illumination does not suffice, or that artificial illumination is required); or the like. Optionally, each one of cameras  151 - 153  may be able to output data in raw format (e.g., uncompressed, unencoded), or compressed (e.g., using JPEG compression for captured images), or encoded (e.g., using H.264 encoding for captured video). 
     In some embodiments, optionally, top-panel camera  153  may acquire images and/or videos simultaneously while front-side camera  151  captures images and/or videos, and/or simultaneously while back-side camera  152  captures images and/or videos. This may allow a user, for example, to acquire multiple concurrent images or multiple concurrent videos, of a three-dimensional event or scene. In some embodiments, for example, the user may command the device  100  to simultaneously capture images and/or videos in all three cameras  151 - 153 , or in two out of the three cameras  151 - 153 , thereby capturing a scene or an event from multiple angels. For example, a user may hold the device  100  generally vertically, or generally perpendicularly to the ground, and may stand in an open field on a cloudy or rainy day; the top-side camera  151  may capture an image or a video of a bird flying above the user, or may capture an image or a video of a cloud or a lightning in the sky; and concurrently, the front-side camera  151  may capture an image or a video of the user&#39;s face, or of a house that appears in the scene behind the user&#39;s body; and concurrently, the back-side camera  152  may capture an image or a video of the opposite side of the scene, for example, a field of flowers or a dog running. This may allow the user to capture multiple concurrent images (or videos) from a single device, the images or videos in opposite directions or in perpendicular directions. Optionally, the device  100  may be configured to allow concurrent one-click operation (e.g., activation and/or deactivation) of all three cameras  151 - 153 , such that a single click or a single user-command may suffice to concurrently activate or concurrently operate all three cameras  151 - 153 , thereby providing a user-friendly and efficient mechanism to capture such multi-perspective images or videos. 
     Reference is made to  FIGS. 2A ,  2 B and  2 C, which are schematic illustrations of an electronic device  200  in accordance with some demonstrative embodiments of the invention. Electronic device  200  may be generally similar to electronic device  100  of  FIGS. 1A ,  1 B and  1 C. 
       FIG. 2A  shows device  200  from a first perspective, showing particularly its front-side face and its touch-screen; while  FIG. 2B  shows device  200  from a second perspective, showing particularly its back-side face; while  FIG. 2C  shows device  200  from a third perspective, in which device  200  stands “upside down” (or, stands “on its head”) and showing its front-side face. 
     Device  200  may have multiple faces, or multiple sides, or multiple panels; for example, device  200  may be generally a rectangular cuboid and may have six faces  101 - 106 . In some embodiments, face  101  may have, or may include, or may house or store, or may have integrated therein, camera  151  and optionally illumination unit  181 . Additionally or alternatively, face  102  may have, or may include, or may house or store, or may have integrated therein, camera  152  and optionally illumination unit  182 . Additionally or alternatively, face  103  may have, or may include, or may house or store, or may have integrated therein, camera  153  and optionally illumination unit  183 . Additionally or alternatively, face  104  may have, or may include, or may house or store, or may have integrated therein, camera  154  and optionally illumination unit  184 . Additionally or alternatively, face  105  may have, or may include, or may house or store, or may have integrated therein, camera  155  and optionally illumination unit  185 . Additionally or alternatively, face  106  may have, or may include, or may house or store, or may have integrated therein, camera  156  and optionally illumination unit  186 . 
     Accordingly, device  200  may include, for example, one camera; or two cameras facing different directions; or three cameras facing different directions; or four cameras facing different directions; or five cameras facing different directions; or six cameras facing different directions. 
     In some embodiments, device  200  may have exactly one camera out of the six optional cameras  151 - 156 . In other embodiments, device  200  may have exactly two cameras out of the six optional cameras  151 - 156 . In other embodiments, device  200  may have exactly three cameras out of the six optional cameras  151 - 156 . In other embodiments, device  200  may have exactly four cameras out of the six optional cameras  151 - 156 . In other embodiments, device  200  may have exactly five cameras out of the six optional cameras  151 - 156 . In other embodiments, device  200  may have exactly six cameras (namely, all six cameras) out of the six optional cameras  151 - 156 . 
     In some embodiments, one or more of the cameras  151 - 156  of device  200  may enable a user to utilize the camera for covert operations, for secretly capturing images and/or videos, for spying or data collection, or the like. In a demonstrative implementation, for example, device  200  may include camera  155  located in face  105 ; and camera  155  may face, generally, towards the right side of device  200  and/or its user; thereby allowing the user of device  200  to capture images and/or videos of a person or object or scene located to the right side of the user, without turning the user&#39;s body or hand towards that direction, and without turning or tilting or slanting device  200  towards that direction. 
     In some embodiments, device  100  and/or device  200  may allow a user to capture a panoramic image or panoramic video; or to capture a semi-spherical or a full-spherical scene. Optionally, an image stitching module or a video stitching module may be used in order to stitch together (or otherwise assemble or fuse together) multiple images, or multiple video frames, in order to generate a panoramic image or video, a 180 degrees image or video, a 270 degrees image or video, a 360 degrees image or video, or the like. For example, the stitching module may identify overlapping regions among multiple images or video frames, and may connect or assemble images or video frames by using such overlapping regions as connection region or assembly regions. 
     In some embodiments, device  100  and/or device  200  may include a camera selector module, allowing a user, for example: to select one or more camera(s) that will capture image(s) and/or video(s) when the user presses or clicks or taps on a “record” button (e.g., an on-screen record button); to select one or more camera(s) that the touch-screen of the device  100  or  200  will show their field-of-view or scene, thereby enabling the user to switch or rotate among multiple cameras in order to view on the touch-screen the view that is seen from each one of such cameras  151 - 156 . In some embodiments, a split-screen module may be included in the device, and may show to the user multiple views from multiple cameras (out of cameras  151 - 156 ), as multiple rectangles or multiple squares on the touch screen, or as a picture-in-picture or side-by-side arrangement, thereby enabling concurrent or simultaneous viewing of the scenes that each such camera is capturing (or is about to capture, or is ready to capture). 
     The term “camera” or “image sensor” or “imager” as used herein may optionally include, in some embodiments, a pair of two cameras (or two image sensors, or two imagers), which may be located on the same face or on the same plane, and may be slightly spaced apart from each other (e.g., approximately 10 or 12 or 15 or 20 or 24 or 30 millimeters apart), able to simultaneously capture images and/or videos, thereby allowing such pair-of-cameras to capture three-dimensional (3D) images or videos, or stereoscopic images or videos, or, to capture images or videos which may then be processed or modified in order to provide to a viewer an experience similar to viewing a 3D image or a 3D video. In some embodiments, each one of (or, any one of) cameras  151 ,  152 ,  153 ,  154 ,  155  and/or  156  may be implemented as such pair-of-cameras or as dual-adjacent-cameras. 
     Reference is made again to  FIG. 1A , as well as to  FIG. 1D  and  FIG. 1E , which are schematic illustrations of an electronic device in accordance with some demonstrative embodiments of the invention.  FIG. 1A  shows device  100 , in which the top-side camera  153  (and the top-side illumination unit  183 ) are located at the center of top-side panel  103 , or, are located within the central one-third region of top-side panel  103 .  FIG. 1D  shows a similar device  100 D, which may be generally similar to device  100 ; but in device  100 D, the top-side camera  153  (and the top-side illumination unit  183 ) are located at the leftmost region of top-side panel  103 , or, are located within the leftmost one-third region of top-side panel  103 .  FIG. 1E  shows a similar device  100 E, which may be generally similar to device  100 ; but in device  100 E, the top-side camera  153  (and the top-side illumination unit  183 ) are located at the rightmost region of top-side panel  103 , or, are located within the rightmost one-third region of top-side panel  103 . Other suitable locations or positions may be used, for top-side camera  153 , or similarly, for any of the other optional cameras  151 - 156  which may be included in such device  100 ,  100 D or  100 E, or in device  200 . 
     In some embodiments, a front-side panel (or a front-side face) of the device (e.g., device  100 , device  200 , or the like) may comprise a screen or a touch-screen.
