     FIELD OF THE INVENTION 
     The present invention relates to vehicles with cameras mounted thereon and in particular to vehicles with exterior-facing cameras, such as forward facing cameras and/or sideward facing cameras and/or rearward facing cameras. 
     BACKGROUND OF THE INVENTION 
     Use of imaging sensors in vehicle imaging systems is common and known. Examples of such known systems are described in U.S. Pat. Nos. 5,949,331; 5,670,935 and/or 5,550,677, which are hereby incorporated herein by reference in their entireties. 
     SUMMARY OF THE INVENTION 
     The present invention provides a vision system that utilizes one or more cameras or image sensors to capture image data of a scene exterior (such as forwardly) of a vehicle and provides a display of images indicative of or representative of the captured image data. The system of the present invention processes the image data and reproduces the images as avatars or virtual representations of the actual or real objects and scene present in the field of view of the camera or cameras of the vision system. The system of the present invention thus may provide an enhanced display of images in a high resolution manner and may provide enhanced texturing and coloring of the displayed images, while utilizing lower resolution cameras and/or reduced image processing devices and/or techniques. Optionally, the system may produce or create a full image of an object that is only partially present in the field of view of the camera, in order to enhance the display for viewing and understanding by the driver of the vehicle. 
     The present invention provides a vision system for a vehicle that includes at least one image sensor disposed at a subject vehicle and having a field of view exterior of the vehicle. A control, at least in part responsive to said image sensor, is operable to generate an avatar representative of at least one object or scene segment in the field of view of the image sensor. The vision system includes a display for displaying the avatar for viewing by a driver of the subject vehicle. 
     Optionally, the at least one image sensor may comprise a forward facing camera disposed at the subject vehicle. Optionally, the vision system is operable to display an avatar that is a substantial representation of an object that is only partially viewed by the image sensor to enhance the display for viewing and understanding by the driver of the subject vehicle. For example, the control may generate the avatar so that a portion of the displayed avatar representing a portion of the object is displayed as a phantom image to represent that viewing of that portion of the object by the image sensor is partially obstructed. Optionally, the control may generate the avatar so that a portion of the displayed avatar representing a portion of the object that is outside of the field of view of the image sensor is displayed as a phantom image. 
     Optionally, the control may generate the avatar with an imitated texture. Optionally, the control may be operable to determine objects at least partially present in the field of view of the image sensor and the control may deemphasize objects that are determined to be less important to the driver of the vehicle during a driving maneuver. For example, the control may deemphasize objects by at least partially removing the objects from the displayed image. 
     These and other objects, advantages, purposes and features of the present invention will become apparent upon review of the following specification in conjunction with the drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now to the drawings and the illustrative embodiments depicted therein, a vehicle  10  includes an imaging system or vision system  12  that includes one or more imaging sensors or cameras (such as a rearward facing imaging sensor or camera  14   a  and/or a forwardly facing camera  14   b  at a front portion of the vehicle (or at the windshield of the vehicle and viewing through the windshield and forwardly of the vehicle), and/or a sidewardly/rearwardly facing camera  14   c ,  14   b  at the sides of the vehicle), which capture images exterior of the vehicle, with the cameras having a lens for focusing images at or onto an imaging array or imaging plane of the camera ( FIG. 1 ). The vision system  12  is operable to process image data captured by the cameras and may provide displayed images at a display device  16  for viewing by the driver of the vehicle. Optionally, the vision system may process image data to detect objects, such as objects to the rear of the subject or equipped vehicle during a reversing maneuver, or such as approaching or following vehicles or vehicles at a side lane adjacent to the subject or equipped vehicle or the like. 
     Due to data loss and natural or artificial blurring along the image processing chain, natural textures of the displayed environment are not reproduced in a satisfying manner unless very high resolution cameras are used. By the nature of the wide angle or fish eye lens typically used in automotive vision systems, especially for surround view vision systems and the like, the resolution of textures off center is much lower than at the center of the captured image (where the distortion due to the wide angle lens is reduced). Because of this, the textures are not reproduced evenly from the center to the farther edges when a top view is generated by image distortion and image stitching (see, for example,  FIG. 5 ). The problem becomes worse when there is data compression and decompression within the image processing chain. 
     A solution of the present invention provides an augmented image or virtual image or avatar to provide enhanced image processing and/or display. Instead of generating an image in any kind of automotive view (front view, rear view, cross traffic view, surround view and/or the like) by deskewing, cropping, distorting and stitching and employing highly sophisticated brightness and color controls for the camera subsequent image enhancement algorithm, the system of the present invention may generate the requested views as augmented reality image reproductions. 
     It is easy to handle and achieve sharp, bright, unblurred images without glaring, halos or noise when all image components are fully computer generated or augmented instead of using real images captured by cameras (in real time). The data amounts are small and the necessary computing power and bandwidth demands are small or minimal. The key information may be easier and faster to perceive by a human eye/brain when looking at an augmented images instead of a real image. 
     Augmented reality views in general may have been proposed for use in automotive vision, and using overlays is already a kind of augmented reality. Also, it may be already known to reduce the level of details which become shown (at all) or highlighted as overlays and also to have sophisticated algorithms to prioritize which details may be chosen for showing or highlighting. 
     The system of the present invention provides a method or means for mapping textures, such as can be seen with reference to  FIG. 6 . The method will allow the vision system or manufacturer of the vehicle or vision system to employ preferably low level (such as lower resolution) cameras, system environment and algorithm in terms of low resolution and/or low sensor performance and/or low lens quality and/or no or poor level of calibration procedures in use and/or data line bandwidth while employing high compression rates. The necessary resolution of a camera may be about 1/10 of the typically used Megapixel cameras. The present invention uses the cameras just to capture the environment&#39;s shape and to detect the present features and textures type. The presented human view then is an augmented reality according to the actively chosen view with imitated texture. 
     The view&#39;s structure may be quite similar to the usually employed views (such as a front view, rear view, cross traffic view, surround view and/or the like), which are generatable out of the cameras&#39; captured images, and/or there may also be artificial views which are unknown or typically not used, since these were heretofore not directly producible based on the cameras&#39; captured images or image data. For example a virtually elevated view point into the forward direction may be new, which may serve a better perceptibility, may be possible by augmented view construction (such as, for example, as shown in  FIG. 4 ). 
     As can be seen with reference to  FIGS. 2-4 , the subject vehicle  10  may be following another vehicle  18  (such as the truck in  FIGS. 2-4 ), which may in turn be following a third vehicle  20 . As shown in  FIG. 3 , the view of the leading vehicle  20  (as viewed by the forward facing camera) may be partially obstructed or blocked by the second vehicle  18 , whereby the driver may not readily appreciate or discern the presence of the leading vehicle ahead of the second vehicle. As shown in  FIG. 4 , the system may generate a display whereby a portion  20   a  of the leading vehicle  20  may be shown in phantom (such as by using dashed or phantom lines or such as by using translucent coloring schemes or the like) so that the driver can readily discern the presence of the leading vehicle ahead of the vehicle that he or she is directly following. The vision system, via image processing of image data captured by the forward facing camera, may determine the presence of the leading vehicle (or other objects or vehicles that are only partially present in the field of view of the camera, either because the view of part of the object is obstructed or because part of the object is located outside of the field of view itself) and may determine or approximate the portion that is missing or obstructed and may generate an avatar or approximation or animation of the missing or obstructed portion of the object to enhance the viewing and discernibility of that object to the driver that is viewing the displayed generated images on the display screen. 
     For example, if a portion of a vehicle is viewed by the camera (such as shown in  FIG. 3 ), the system may detect the portion of the vehicle and may (such as via image processing of image data captured by the camera) determine what the viewed portion is (such as a portion of a vehicle or a portion of a sign or a portion of a tree or other object) and, responsive to that determination, the system estimates or determines what the non-viewed portion may look like (such as via using a generic representation, such as a generic vehicle for a determined partially hidden vehicle, or via an estimation based on the part of the vehicle or object that is viewed by the camera). The system then generates an avatar or animation of the missing portion to fill in the parts that are missing (and optionally, the system may generate an avatar or animation of the determined object or vehicle and overlay the avatar over the object or vehicle, including the portion or portions of the object or vehicle that are viewed by the camera), and displays or overlays the avatar or animation onto displayed images. Optionally, the avatar or animation may be generated as part of a heads up display so as to be projected into the driver&#39;s field of view at a location that approximates where the driver&#39;s line of sight would be to the determined object or vehicle. The present invention thus provides an avatar or animation of at least the missing portions of vehicles and/or objects in the field of view of the vehicle camera (such as the forward viewing camera as described above or such as a rearward or sideward viewing camera, so as to assist the driver in reversing maneuvers and/or lane change maneuvers or the like) to enhance the driver&#39;s viewing and understanding of the presence of objects or vehicles in the scene in the path of travel of the vehicle. 
     It is known to use the likes of a rearward facing video camera and/or other exterior viewing cameras to capture video images of scenes/objects exterior the vehicle while the vehicle is, for example, traveling along a highway or executing a backup maneuver or reversing into a parking place. Such systems provide video displays, often in color and in high definition, that display video images of what is seen and captured by the automotive video cameras. It is left to the driver to view and to assimilate the video images being displayed to him or her in real time. Often, the driver is interested in an activity or an object or a portion of the videoed scene, and seeks to distinguish that sub-scene of interest from other vehicles and/or objects and/or items being simultaneously videoed. In this regard, the driver&#39;s task would be made easier if such non-critical and/or ancillary and/or extraneous items/objects/scene portions were not present or at least had their presence removed or substantially removed or mitigated. 
     In accordance with the present invention, the video images captured by the at least one automotive exterior viewing video camera are fed to, and are image processed by, an image processor (such as, for example, an EYEQ™ image processing chip available from Mobileye Vision Technologies Ltd. of Jerusalem, Israel). In addition to detecting the presence and position of a given object in the videoed scene, the image processor creates an avatar or reproduction or simulation or virtual image of the given object. And the video image processor utilized, in whole or in part, substitutes or replaces or overlays on the real time video image of the subject object with the avatar simulation in such a manner that enhances the driver&#39;s viewing and understanding of the imaged scene. Thus, non-critical vehicles or objects or road side scenery can be de-emphasized and/or removed so that video display emphasizes and/or is focused on particular items or objects or scene segments of criticality to the driver at any given moment in time. Thus, use of an avatar or incarnation or virtual reality image (comprising an electronic image of at least a portion of the videoed scene that can then be manipulated by a video/image processor) allows the displayed images to be manipulated to emphasize or deemphasize selected portions of the videoed scene and/or selected objects or the like present in the videoed scene. 
     For example, when the driver is reversing the subject or equipped vehicle into a vacant parking space, video images of objects or other vehicles that are not immediately adjacent the vacant parking place or space may be deemphasized and/or removed or partially removed (such as by rendering them semi-transparent or mostly transparent and/or replacing them with avatars or the like). Thus, the driver can readily focus on the displayed video images of importance while executing the reversing maneuver. However, should one of the deem phasized or removed objects move from its parked position (where it was determined to be not highly relevant to the current reversing maneuver of the subject vehicle), such movement may render that object or vehicle a more important or relevant or critical item for viewing by the driver executing that particular parking maneuver. If so, the moving and now important object or other vehicle (or pedestrian or the like) may be viewed in real-time video (not as an avatar), so as to enhance the viewability and discernibility of the object or other vehicle or pedestrian to the driver of the reversing subject vehicle. 
     To reproduce the impression of an outside scene the scene&#39;s structure and/or general shape may be reproduced and the texture imitated by a mapping texture out of a library. The library may contain several kinds of surfaces which may appear in a vehicle&#39;s environment. For example, there may be any grains, granularities and colorations of asphalt, gravel, dirt, sand, water surface (puddle), snow, ice interlocking pavement, tiling, boarding, laminate and/or the like. The mapping texture may have a logical order. The texture which is closest to that in real at that specific position may be chosen (such as via a texture matching method or protocol that selects the appropriate or “closest” texture for the object to be imaged. To avoid abrupt thresholds in texture there may be just one texture type reproduced in the augmented view even when different textures are found in the real source image(s) as long as a wide level of similarity is still given. Texture thresholds which are really present in nature may be reproduced by two border lining textures in the augmented view. 
     Objects on the ground, which are large enough to be perceived and specified by the cameras, may be reproduced as well. For example, sharp and clean gully covers may be mapped onto the same position (on the floor) within the augmented view as found in reality, also when the gullies in reality are cracked and dirty. As known, objects such as an adult human, child, bicycle, vehicle, car, truck, policeman on a horse, other animals, such as a cow, cat or dog or the like, a pole, snow pile, parking place markings, a pylon, a construction site boundary or the like, may be mapped unified into the augmented reality scene. The mapping may be flat or done by using 2D or 3D imposters. Any kind of bump mapping may become used (such as by utilizing aspects of the systems described in International Publication Nos. WO 2013/086249, published Jun. 13, 2013, and/or WO 2013/109869, published Jul. 25, 2013, which are hereby incorporated herein by reference in their entireties). 
     When a 3D reconstruction of the real world objects and scene can be achieved, the mapping may be direct to the same structure as the 3D reconstructed world or the 3D objects may be unified for a certain level (such as when two real vehicles have been detected correctly as vehicles (out of the cameras images), these may be reproduced as two uniform looking cars or different trucks as uniform trucks, and the like). There may be just differences in colors, but these may also be uniformed depending on the size/number of possible textures and shapes of objects present in the library. Unlike in reality, non-transparent objects may be shown as semi-transparent, dotted or dithered to allow to perceive the scene behind an object (such as shown in  FIG. 4 , where a portion of the vehicle that is ahead of the truck is shown as dashed lines or the like so as to be “seen” through the truck). Highlighting (such as blinking, flashing, waving, colored, color changing and the like) warning symbols, arrows, tags, POIs and driving tunnels may come into use as well. The texture library may come with or be part of or incorporated in the automotive vision system, or may be provided by a server or cloud or the like (whereby the vision system may access the remote server via a telematics system of the vehicle or the like) and/or may be updated from time to time via remote or by a service device or by download or via a cell phone channel. 
     Thus, the present invention provides a vision system that captures image data of a scene exterior (such as forwardly) of the vehicle and provides a display of images indicative of the captured image data. The system of the present invention processes the image data and reproduces the images as representations of the actual or real objects and scene present in the field of view of the camera or cameras of the vision system. The system of the present invention thus may provide an enhanced display of images in a high resolution manner and may provide enhanced texturing and coloring of the displayed images, while utilizing lower resolution cameras and/or reduced image processing devices and/or techniques. 
     The camera or sensor may comprise any suitable camera or sensor. Optionally, the camera may comprise a “smart camera” that includes the imaging sensor array and associated circuitry and image processing circuitry and electrical connectors and the like as part of a camera module, such as by utilizing aspects of the vision systems described in International Publication Nos. WO 2013/081984 and/or WO 2013/081985, which are hereby incorporated herein by reference in their entireties. 
     The system includes an image processor operable to process image data captured by the camera or cameras, such as for detecting objects or other vehicles or pedestrians or the like in the field of view of one or more of the cameras. For example, the image processor may comprise an EYEQ2 or EYEQ3 image processing chip available from Mobileye Vision Technologies Ltd. of Jerusalem, Israel, and may include object detection software (such as the types described in U.S. Pat. Nos. 7,855,755; 7,720,580 and/or 7,038,577, which are hereby incorporated herein by reference in their entireties), and may analyze image data to detect vehicles and/or other objects. Responsive to such image processing, and when an object or other vehicle is detected, the system may generate an alert to the driver of the vehicle and/or may generate an overlay at the displayed image to highlight or enhance display of the detected object or vehicle, in order to enhance the driver&#39;s awareness of the detected object or vehicle or hazardous condition during a driving maneuver of the equipped vehicle. 
     The vehicle may include any type of sensor or sensors, such as imaging sensors or radar sensors or lidar sensors or ladar sensors or ultrasonic sensors or the like. The imaging sensor or camera may capture image data for image processing and may comprise any suitable camera or sensing device, such as, for example, an array of a plurality of photosensor elements arranged in at least 640 columns and 480 rows (preferably a megapixel imaging array or the like), with a respective lens focusing images onto respective portions of the array. The photosensor array may comprise a plurality of photosensor elements arranged in a photosensor array having rows and columns. The logic and control circuit of the imaging sensor may function in any known manner, and the image processing and algorithmic processing may comprise any suitable means for processing the images and/or image data. 
     For example, the vision system and/or processing and/or camera and/or circuitry may utilize aspects described in U.S. Pat. Nos. 7,005,974; 5,760,962; 5,877,897; 5,796,094; 5,949,331; 6,222,447; 6,302,545; 6,396,397; 6,498,620; 6,523,964; 6,611,202; 6,201,642; 6,690,268; 6,717,610; 6,757,109; 6,802,617; 6,806,452; 6,822,563; 6,891,563; 6,946,978; 7,859,565; 5,550,677; 5,670,935; 6,636,258; 7,145,519; 7,161,616; 7,230,640; 7,248,283; 7,295,229; 7,301,466; 7,592,928; 7,881,496; 7,720,580; 7,038,577; 6,882,287; 5,929,786 and/or 5,786,772, and/or International Publication Nos.
