Title: Imaging Apparatus For Image Integration

Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of provisional patent application No. 61/113,222 titled “Imaging Apparatus For Image Integration”, filed on Nov. 10, 2008 in the United States Patent and Trademark Office. 
     The specification of the above referenced patent application is herein incorporated by reference in its entirety. 
    
    
     BACKGROUND 
     This disclosure, in general, relates to image capturing and processing, and more particularly, relates to integrating a first image of an operator into a second image that does not include an image of the operator, whereby desired image combinations and effects may be achieved. 
     Cameras and other imaging devices are typically used by an operator to capture images. Conventional cameras comprise a photographic lens mounted on the front of the camera, a viewfinder, a preview screen, and various camera controls located on the rear and around the periphery of the camera. The operator may use the viewfinder, the preview screen, and the camera controls to capture an image of a focused area distal of the front side of the camera. This image is captured, of course, exclusive of any image of the operator who is behind the camera. If, for example, an image of a group of people is to be captured by an operator using a camera, that operator must operate the camera and therefore will not appear in the image. A person from outside the group of people would normally be required to capture an image which includes all the people. The person requested to capture the image may be a stranger and this may not always be desirable and may create an uncomfortable situation. 
     A self timer feature of the camera may be used to capture an image inclusive of all the people. However, the self timer feature requires precise camera and subject positioning and physical abandonment of the camera by the operator, making the camera susceptible to shake, instability, falling, improper centering of an image, theft, etc. Furthermore, the operator needs to set a countdown for the self timer and return to a desired position in the focused area before the countdown period expires. Under these circumstances, the operator is unable to preview the image immediately prior to the capturing of the image. 
     Hence, there has been a long existing need in the art for an imaging apparatus that integrates a first image of an operator into a second image that does not include the image of the operator and overcomes the aforementioned difficulties and deficiencies. 
     SUMMARY 
     This summary is provided to introduce a selection of concepts in a simplified form that are further described in the detailed description of the invention. This summary is not necessarily intended to identify key or essential inventive concepts of the claimed subject matter, nor is it intended for determining the scope of the claimed subject matter. 
     The method and imaging apparatus disclosed herein addresses the above stated need for integrating a first image into a second image. An image capture device comprising at least one first lens and at least one second lens is provided to an operator. The first lens is positioned in a rearward facing location on the image capture device which focuses in directions, for example, the rear direction, so as to capture an image of an operator or the like. The second lens is positioned in a forward facing location on the image capture device which focuses in directions, for example, the forward direction so as to capture a second image. An image integration software application is provided on the image capture device. The image integration software application utilizes an interface on the image capture device. The operator previews the second image using the image capture device. The operator selects a location in the previewed second image on the interface for the integration. The operator selects the location in the previewed second image using, for example, a touch screen or multiple selection control buttons provided on the image capture device. The operator selects the previewed second image using the selection control buttons. The image integration software application activates the first lens and the second lens for enabling the capture of the first image and the capture of the previewed second image respectively. 
     The operator captures the previewed second image using the second lens of the image capture device. The operator simultaneously captures the first image using the first lens of the image capture device. The image capture device may comprise a first flash unit and a second flash unit synchronized and coordinated via suitable monitoring and control software, including, for example, light sensors, for providing illumination during the capture of the first image and the previewed second image, respectively. A flash control unit is provided on the image capture device for selectively controlling the illumination level and timing of the first flash unit and the second flash unit during the capture of the first image and the previewed second image. Light sensors may be provided on the image capture device for sensing the amount of light incident on the first lens and the second lens during the capture of the first image and the previewed second image. 
     The image integration software application integrates the captured first image and the captured second image at the selected location to create a composite image. For example, either the captured first image is superimposed over the captured second image or the captured second image is superimposed over the captured first image to create the composite image. The captured first image, for example, includes the operator and the captured second image does not include the operator. Therefore, the first image of the operator is integrated into the second image that does not include the operator using the image capture device. The created composite image therefore includes the image of the operator in the second image. Multiple capture control buttons are provided on the image capture device for providing flexible options to the operator during the capture of the first image and the previewed second image. The image integration software application processes the captured first image, the captured second image, and the composite image based on preferences of the operator. The operator sets the preferences on the image capture device using one or more of the selection control buttons. The created composite image is displayed on the interface on the image capture device. 
     In an embodiment of the method and imaging apparatus disclosed herein, the operator has an option of inserting a third image, for example, an image of the operator, as a signature in a forward captured image using one of the selection control buttons. After one of the selection control buttons is pressed, the image integration software application inserts the operator&#39;s image into the forward captured image as the signature at a predefined location on the captured image or at a location selected by the operator.

     DETAILED DESCRIPTION 
     Referring now to the drawings wherein like reference numerals denote like or corresponding parts, elements, components or steps, throughout the drawings.  FIG. 1  illustrates a method of integrating a first image into a second image. An image capture device comprising a first optical unit and a second optical unit is provided  101  to an operator. The first optical unit and the second optical unit refer to lenses and other optical elements that enable the generation of images. Herein, the first optical unit is exemplarily referred to as a “first lens” and the second optical unit is exemplarily referred to as a “second lens”. For purposes of illustration, the detailed description refers to a first lens and a second lens; however the scope of the method and imaging apparatus disclosed herein is not limited to a single first lens and a single second lens but may be extended to include multiple first lenses and second lenses provided on the image capture device that are used to capture images from different directions. The first lens is positioned in a rearward facing location on the image capture device which focuses in directions, for example, the rear direction, so as to capture an image of an operator or the like. The second lens is positioned in a forward facing location on the image capture device which focuses in directions, for example, the forward direction so as to capture a second image. 
     An image integration software application is provided  102  on the image capture device. The image integration software application may comprise any suitable programming language that can be compiled for execution on the image capture device. The image integration software application may be implemented using, for example, a C programming language, a C++ programming language, Java™ Micro Edition, and other programming languages known to one of ordinary skill in the art for image systems by camera designers familiar with camera and imaging controls, touch screen technology and the like. The image integration software application utilizes an interface on the image capture device. The operator previews  103  the second image using the image capture device. The second image is, for example, an image of multiple subjects excluding the operator. For example, the second image may be an image of friends of the operator at a park. 
     The operator selects  104  a location in the previewed second image on the interface for the integration. The operator selects the location in the previewed second image using a touch screen or multiple selection control buttons provided on the image capture device. The operator may also select the previewed second image using the selection control buttons. The image integration software application activates the first lens and the second lens for enabling the capture of the first image and the capture of the previewed second image respectively. The operator captures  105  the previewed second image using the second lens of the image capture device. The operator then captures  106  the first image using the first lens of the image capture device. The first image is, for example, an image of the operator. The image integration software application integrates  107  the captured first image and the captured second image at the selected location to create a composite image. The integration comprises superimposing the captured first image over the captured second image or the captured second image over the captured first image. The captured first image, for example, includes the operator and the captured second image, for example, does not include the operator. Therefore, the first image of the operator is integrated into the second image that does not include the operator using the image capture device. The created composite image therefore includes the image of the operator in the second image. The created composite image is displayed on the interface on the image capture device. 
     The image integration software application processes the captured first image, the captured second image, and the composite image based on preferences of the operator. The operator sets the preferences using one or more of the selection control buttons. 
       FIG. 2  exemplarily illustrates a block diagram of an imaging apparatus  200  that integrates a first image into a second image. The imaging apparatus  200  comprises an image capture device  201 , an image integration software application  213 , and an interface  214  controlled by the image integration software application  213 . The image capture device  201  is, for example, a digital camera, a digital video camera, a mobile phone, medical imaging devices, or any other suitable imaging device. The image capture device  201  comprises a preview unit  202 , a location selection unit  210 , a first lens  203 , a second lens  204 , a first flash unit  206 , a second flash unit  207 , multiple capture control buttons  205 , a flash control unit  208 , and one or more light sensors  209 . The image integration software application  213  comprises a lens activation module  213   a,  a support module  213   b,  an integration module  213   c,  and a signature module  213   d.    
     The preview unit  202  of the image capture device  201  enables the operator to preview the second image. The preview unit  202  also comprises a display screen, for example, a liquid crystal display, for previewing the second image. The display screen is, for example, a touch screen  212  as exemplarily illustrated in  FIG. 2  and  FIG. 4  or a standard display  301  as exemplarily illustrated in  FIG. 3 . The location selection unit  210  enables the operator to select a location  401  in the previewed second image for the integration. The location selection unit  210  comprises multiple selection control buttons  211 . The location selection unit  210  enables the operator to select the location  401  in the previewed second image using the touch screen  212  or the selection control buttons  211 . The operator sets preferences on the image capture device  201  using one or more of the selection control buttons  211  and the capture control buttons  205 . The interface  214  under control of the image integration software application  213  accepts the location  401  selected by the operator. The operator selects the location  401  using a combination of the interface  214  and the location selection unit  210 . The first lens  203  is positioned in a rearward facing location on the image capture device  201  and the second lens  204  is positioned in a forward facing location on the image capture device  201 . The first lens  203  captures the first image and the second lens  204  captures the previewed second image. The lens activation module  213   a  of the image integration software application  213  activates the first lens  203  or the second lens  204  on the image capture device  201  for capture of the first image and the previewed second image respectively. The support module  213   b  supports the first lens  203  and the second lens  204  for providing the first image and the second image from different directions. The support module  213   b  instructs the lens activation module  213   a  to activate any of the first lenses  203  and/or the second lenses  204  provided on the image capture device  201  based on the operator&#39;s preference to capture images from different directions without having to change the position of the image capture device  201 . For example, if the operator wishes to take an image of himself/herself without having to reverse the imaging apparatus  200 , the support module  213   b  instructs the lens activation module  213   a  to activate any of the first lenses  203  positioned in a rearward facing location on the image capture device  201  for capturing the operator&#39;s image. Similarly, if the operator wishes to integrate his/her image into a background image, the support module  213   b  instructs the lens activation module  213   a  to activate a first lens  203  facing the operator for capturing the operator&#39;s image and to activate any of the second lenses  204  positioned in the forward facing locations on the image capture device  201  that face the desired background for capturing the background image of choice for the integration. 
     The first flash unit  206  and the second flash unit  207  provide illumination during the capture of the first image and the capture of the previewed second image respectively. The operator captures the first image and the previewed second image using the capture control buttons  205 . The capture control buttons  205  also provide the operator with flexible options while capturing the first image and the previewed second image. 
     The flash control unit  208  selectively controls the illumination level and timing of the first flash unit  206  and the second flash unit  207  during capture of the first image and capture of the previewed second image respectively. The light sensors  209  sense the amount of light incident on the first lens  203  and the second lens  204  during capture of the first image and the capture of the second previewed image. The flash control unit  208  controls intensity of illumination of the first flash unit  206  and the second flash unit  207  during capture of the first image and the previewed second image for matching lighting conditions of both the first image and the previewed second image. The light sensor  209  provides the flash control unit  208  with data regarding lighting conditions in front of the first lens  203  and the second lens  204 , thereby allowing the flash control unit  208  to control intensity of illumination and control selective illumination of the first flash unit  206  and the second flash unit  207  during capture of the first image and the previewed second image. 
     The integration module  213   c  selectively integrates the captured first image and the captured second image at the selected location to create a composite image. The integration module  213   c  facilitates combination of image effects of the first image and the second image in the created composite image. The integration module  213   c  superimposes the captured first image and the captured second image at the selected location  401 . The integration module  213   c  superimposes the captured first image over the captured second image or the captured second image over the captured first image. The captured first image includes the operator and the captured second image does not include the operator. The image integration software application  213  also fades edges of the captured first image to blend with the captured second image. The image integration software application  213  saves the second image and the superimposed first image as a single composite image. 
     Instructions for executing the image integration software application  213  are retrieved by a processor from a program memory of the image capture device  201  in the form of signals. Location of the instructions in the program memory is determined by a program counter (PC). The program counter stores a number that identifies the current position in the program of the image integration software application  213 . 
     The instructions fetched by the processor from the program memory after being processed are decoded. After processing and decoding, the processor executes the instructions. For example, the integration module  213   c  defines instructions for selectively integrating the first image generated by the first lens  203  and the second image generated by the second lens  204  to facilitate combination of image effects of the generated first image and the generated second image in a composite image. The processor retrieves the instructions defined by the integration module  213   c  and executes the instructions. 
     The signature module  213   d  of the image integration software application  213  inserts a third image, for example, an image of the operator, into a captured image, for example, the captured first image, the captured previewed second image, or the composite image, as a signature. The signature module  213   d  instructs the lens activation module  213   a  to activate the first lens  203  for capture of an image of the operator for insertion into a captured second image, as a signature. 
       FIGS. 3-4  exemplarily illustrate rear views of the imaging apparatus  200 . As illustrated in  FIGS. 3-4 , the first lens  203  is mounted at a rearward facing location on the camera body  215  of the image capture device  201 , and the second lens  204  is mounted at a forward facing location on the camera body  215 . The first lens  203  is adapted to capture, for example, the image of an operator and the second lens  204  is adapted to capture a frontal image. As illustrated in  FIGS. 3-4 , the imaging apparatus  200  further comprises multiple capture control buttons  205 . The capture control buttons  205  provide the operator with different options and functions for capturing the first image and the second image. The capture control buttons  205 , for example, provide functions for zoom control, exposure control, image capturing mode control, etc. 
     The image integration software application  213  utilizes the interface  214 . The interface  214  is displayed on the display screen  212  or  301 . The operator selects a location  401  in the previewed second image on the interface  214  for the integration. The operator may select the location  401  by moving an on-screen pointer or cursor (not shown) to the location  401  on the interface  214  displayed on the standard display  301  using one or more of the selection control buttons  211  of the image capture device  201  as exemplarily illustrated in  FIG. 3 , and more fully described subsequently herein. In another example, the operator selects the location  401  by touching a location  401  on the interface  214  displayed on the touch screen  212  using, for example, a stylus or a finger  403 , as exemplarily illustrated in  FIG. 4 . In  FIG. 4 , multiple subjects  402  of the second image are displayed on the touch screen  212  and the operator selects a location  401  among the subjects  402  to integrate the operator&#39;s image. 
     Also illustrated in  FIGS. 3-4  are a front flash unit  207 , a rear flash unit  206 , front and rear light sensors  209 , the capture control buttons  205 , and the selection control buttons  211 . The selection control buttons  211  are, for example, a “Me-N-2” button  211   a,  an “R-Len” button  211   f,  a signature “S” button  211   d,  a size control button  211   e,  etc. The “R-Len” button  211   f  enables an operator to take an image of himself/herself and a friend without having to reverse the imaging apparatus  200 . The “Me-N-2” button  211   a  enables the operator to integrate the captured first image into the captured second image. The “S” button  211   d  enables the operator to insert an image of the operator as a signature or the like in a captured image. The size control button  211   e  is, for example, a roller dial positioned on the side of the image capture device  201  to allow an operator to increase or decrease the size of the first image or the second image based on the operator&#39;s preference. 
     The operator activates an integration mode using one or more of the selection control buttons  211 . The integration mode enables the operator to use the image capture device  201  for the integration. Prior to activation of the integration mode, the image capture device  201  is operated as a conventional image capture device. The operator previews the second image using the image capture device  201 . The second image is, for example, an image of multiple subjects  402  excluding the operator. For example, the second image may be an image of friends of the operator at a park. The image capture device  201  comprises a display screen  212  or  301  for enabling the operator to preview the second image by viewing an area focused by the image capture device  201 . The display screen  212  or  301  is, for example, a standard display  301  as exemplarily illustrated in  FIG. 3  or a touch screen  212  as exemplarily illustrated in  FIG. 4 . 
     The image integration software application  213  also activates the first lens  203  at the rear of the image capture device  201  and the second lens  204  at the front of the image capture device  201  for enabling the capture of the first image, for example, the operator&#39;s image, and the capture of the previewed second image, respectively. The operator captures the previewed second image using the second lens  204  of the image capture device  201 . The operator operates the image capture device  201  from the rear section of the image capture device  201 . Hence, the captured second image does not include an image of the operator. The rear section of the image capture device  201  comprises multiple capture control buttons  205 . The operator captures the previewed second image using the capture control buttons  205 . The capture control buttons  205  also provide the operator with flexible options while capturing the first image and the previewed second image. The front flash unit  207  provides illumination during the capture of the previewed second image. The front flash unit  207  is positioned in a forward facing location on the image capture device  201  facing in the same direction as the second lens  204  of the image capture device  201  as exemplarily illustrated in  FIG. 3 . 
     The operator captures the first image using the first lens  203  of the image capture device  201 . The first image is, for example, the operator&#39;s image. The rear flash unit  206  provides illumination during the capture of the first image. The rear flash unit  206  is positioned in a rearward facing location on the image capture device  201  facing in the same direction as the first lens  203  of the image capture device  201  as exemplarily illustrated in  FIGS. 3-4 . Alternatively, the rear flash unit  206  may be used for illumination during capture of both the first image and the second image. The second image, for example, is not captured before the capture of the first image. The first image of the operator is, for example, captured before the second image is captured, or the first image and the second image are captured simultaneously. 
     The image integration software application  213  superimposes the captured first image over the captured second image or the captured second image over the captured first image at the selected location  401 . The captured first image includes the operator and the captured second image does not include the operator. Therefore, the first image is integrated into the second image using the image capture device  201 . For enabling the image integration to be performed, the image integration software application  213  scales down the resolution of the first image to a fraction of the resolution of the second image. Hence, the smaller first image is overlaid on top of the second image to preferably prevent the first image from obscuring the second image. 
     The image integration software application  213  processes the captured first image, the captured second image, and the composite image based on preferences of the operator. The captured first image is integrated into the captured second image using, for example, a “Me-N-2” button  211   a.  The first lens  203 , for example, takes a picture of only the operator without a background. The second lens  204  captures the background, for example, mountains, buildings, trees, people, etc. The image integration software application  213  then integrates the image of the operator into the image of the background to create a single composite image. Different methods are used to process the captured first and second images using, for example, the software application, eprompt®, a processor board, etc. The image capture device  201  comprises, for example, a face or anatomy recognition unit written in the software of the image integration software application  213  for capturing the image of the operator and placing the image of the operator next to the second image, behind the second image, or between the second images captured by the second lens  204  and saves the first image and the second image into a single composite image. 
     The image integration software application  213  evaluates the field and focal distances of the first image and the previewed second image from the first lens  203  and the second lens  204 . The image integration software application  213  updates the preview of the second image shown to the operator indicating the appropriate image boundaries required for integrating the first image with the second image. The operator then presses one of the capture control buttons  205  to capture the first image and the previewed second image. When the operator takes the picture, both the first and the second images will be captured. The image integration software application  213  first processes the first image for identifying the operator&#39;s face using the face or anatomy recognition unit in the integration module  213   c  of the image integration software application  213 . The image integration software application  213  identifies the boundaries of the operator&#39;s image and extracts the image data representing the operator from the first image. The image integration software application  213  applies an algorithm to differentiate the image of the operator from the background of the first image and performs a mirror reversal of the operator&#39;s image for integration into the second image. 
     The image integration software application  213  also processes the second image and identifies the foreground subjects from the background by applying an algorithm to identify the faces or torsos in the second image. The image integration software application  213  also interprets the focal distance of the subjects in the second image, and scales the operator&#39;s image to a size that represents the operator scaled to the focal distance of the second image&#39;s subjects based on an average arm&#39;s length distance of the operator from the image capture device  201 , or using an actual computed focal distance for the image of the operator if available from the image capture device  201 . The image integration software application  213  applies foreground elements from the first image as identified by an algorithm to the second image and presents a composite image to the operator. The composite image is composed of pixels from both the first image and the second image. 
     The following logic is applied for selection of each pixel from each of the first image and the second image for display in the composite image. Pixels from the second image identified as belonging to faces or torsos in the second image are, for example, rendered first. Pixels from the first image identified as belonging to the face or torso of the operator are rendered next. Pixels from the second image that are identified as not belonging to the faces or torsos of the subjects in the second image are then rendered. The image integration software application  213  supports controls that allow the image of the operator to be moved around the composite image in order to render a desired image. The image integration software application  213  recomputes the composite image and varies the location of pixels from the first image for integration into the second image. The image integration software application  213  computes other unspecified composite images that result from software or hardware based manipulation of the first image and the second image within the image capture device  201  to yield a composite image that incorporates pixels from both the first image and the second image. 
     In an embodiment, the image integration software application  213  fades edges of the captured first image to blend with the captured second image. The image integration software application  213  converts dimensions of the first image during superimposition for blending the first image of the operator with the second image. The image integration software application  213  converts the first image to dimensions proportional to the dimensions of the second image. The image integration software application  213  saves the second image with the superimposed first image as a single composite image on the imaging apparatus  200 . 
     In another embodiment, the first lens  203  and the second lens  204  are also used independently to capture the first image of the operator and the second image respectively. If the first lens  203  and the second lens  204  are used independently, the image capture device  201  functions as a conventional camera. The first lens  203  is, for example, used to capture the first image of the operator without superimposing the first image of the operator on another image. When the first lens  203  is used to capture the first image of the operator without superimposition, the operator previews the first image on the display screen  212  or  301  to ensure correct focus. The operator activates the first lens  203  and the second lens  204  independently using one or more of the selection control buttons  211 , for example, the rear lens “R-Len” button  211   f  as exemplarily illustrated in  FIGS. 3-4 . For example, the operator activates the first lens  203  using the “R-Len” button  211   f  to take an image of himself/herself and a friend without having to reverse the imaging apparatus  200 . In this case, the operator can view himself/herself and the friend on the display screen  212  or  301  and use only the first lens  203  to capture the image of the operator and the friend. 
     In another embodiment, the operator has an option of inserting an image of the operator as a signature in a captured image using one of the selection control buttons  211 , for example, the signature “S” button  211   d  as exemplarily illustrated in  FIGS. 3-4 . When the “S” button  211   d  is pressed, the image integration software application  213  inserts the operator&#39;s image into the captured image in a predefined location or in a location selected by the operator. The image integration software application  213  may automatically insert the operator&#39;s image in a predefined bottom right location or a predefined bottom left direction. Alternatively, the operator may select the location for inserting the operator&#39;s image on the captured image by pressing the “L” button  211   b  and “R” button  211   c  of the image capture device  201  as exemplarily illustrated in  FIG. 3 . Pressing the “L” button  211   b  moves the inserted operator&#39;s image in a general left direction and pressing the “R” button  211   c  moves the inserted operator&#39;s image in a general right direction. The size of the inserted operator&#39;s image is, for example, the size of a postage stamp. 
     The lens activation module  213   a  of the image integration software application  213  activates the first lens  203  or the second lens  204  for capture of the first image and the previewed second image respectively. For example, when the operator presses the “R-Len” button  211   f  on the image capture device  201 , the lens activation module  213   a  activates the first lens  203 . When the operator presses the “Me-N-2” button  211   a,  the lens activation module  213   a  activates both the first lens  203  and the second lens  204 , and also activates the integration mode. 
     The signature module  213   d  of the image integration software application  213  instructs the lens activation module  213   a  to activate the first lens  203  for capture of an image of the operator for insertion into a captured second image, as a signature, when the operator presses the “S” button  211   d  on the image capture device  201 . The signature module  213   d  inserts the captured operator&#39;s image into a predefined location or a location selected by the operator on the captured second image. The signature module  213   d  inserts the captured operator&#39;s image into a predefined bottom right position or a predefined bottom left position. Alternatively, pressing the “L” button  211   b  or “R” button  211   c  on the image capture device  201  moves the inserted operator&#39;s image in a general left or right direction respectively. Repeatedly pressing the “L” button  211   b  and the “R” button  211   c  allows the operator to precisely select the location of the operator&#39;s image on the captured image. 
     Consider an example of an operator John at a party with his friends at a crowded venue. John wants to take a picture of himself with his friends at the party. John does not want to ask a third party, for example, a stranger to take the picture. John also does not want to set a self timer and try and position and support a camera for the image capture or abandon the camera in the crowded venue. Using the imaging apparatus  200  disclosed herein, John does not need to ask a stranger to take the picture or abandon the imaging apparatus  200 . 
     John activates the integration mode of the imaging apparatus  200  by pressing on the location selection unit  210  labeled “Me-N-2” as illustrated in  FIGS. 3-4 . John points the imaging apparatus  200  at his friends and previews a picture of his friends without himself in the picture. John selects a location  401  on the previewed picture of his friends on the interface  214  displayed on the display screen  212  or  301  of the image capture device  201  corresponding to where he would like his picture to be superimposed in the previewed picture. John captures the previewed picture using the image capture device  201 . Simultaneously, John also captures a picture of himself using the image capture device  201 . The first lens  203  of the image capture device  201  takes John&#39;s picture and the second lens  204  takes the picture of his friends without him. In this example, the first image is John&#39;s picture and the second image is the picture of John&#39;s friends without John. 
     The imaging apparatus  200  then superimposes John&#39;s picture over the picture of John&#39;s friends without John, at the selected location  401 , to obtain a picture of John with his friends. The imaging apparatus  200  resizes John&#39;s picture to fit in the picture of John&#39;s friends appropriately. The imaging apparatus  200  saves the picture of John with his friends as a single composite picture. Hence, John has a picture of himself with his friends without using a self timer feature or asking other people to take the picture. 
     John can also use the imaging apparatus  200  to take a picture of himself and a friend without superimposition. John activates the first lens  203  of the image capture device  201  by using the “R-Len” button  211   f  on the image capture device  201 . He then previews his image and his friend&#39;s image on the display screen  212  or  301  of the image capture device  201  without having to reverse the image capture device  201 . He then presses one of the capture control buttons  205  of the image capture device  201  to capture the picture of himself and his friend. 
     Consider another example of using the imaging apparatus  200  as, for example, a digital camera, for integrating images. An operator, for example, John activates the integration mode by pressing the “Me-N-2” on the imaging apparatus  200 . The imaging apparatus  200  captures a second image of a single subject  402  or a group of subjects  402  in front of the imaging apparatus  200  and a first image of the operator, John. The first image of John is integrated into the second image of the subjects  402 , for example, a group of friends. John focuses on his group of friends and then prepares to capture the first image of him. The imaging apparatus  200  is equipped with a preview unit  202 , for example, the liquid crystal display (LCD) with the touch screen  212 . John first views his group of friends on the LCD screen. John then touches the LCD screen at the exact position where he wishes to place himself among his group of friends. The second lens  204  captures the second image of John&#39;s group of friends and the first lens  203  captures the first image of John behind the imaging apparatus  200 . John then presses one of the capture control buttons  205 , for example, a click button, on the imaging apparatus  200  to capture both the first image and the second image simultaneously. The light sensor  209  determines lighting conditions in front of the first lens  203  and the second lens  204  of the image capture device  201 . The flash control unit  208  obtains data regarding the lighting conditions in front of the first lens  203  and the second lens  204  from the light sensor  209 . The flash control unit  208  then controls the illumination of the first flash unit  206  and the second flash unit  207  for enabling the lighting conditions of the first image and the previewed second image to match when the first image and the previewed second image is captured. The first flash unit  206  and the second flash unit  207  of the imaging apparatus  200  hence provide necessary illumination at the time of capturing the images. The first flash unit  206  and the second flash unit  207  are, for example, activated simultaneously while capturing the second and first images respectively. The image integration software application  213  then proportionately places a first image of John at the location  401  selected by John within the second image. 
     Alternatively, the “L” button  211   b  and the “R” button  211   c  as exemplarily illustrated in  FIG. 4 , enables the operator, i.e. John, to select a location  401  within the second image either to the left, the right of the group in the second image. This arrangement is used in the imaging apparatus  200  without the LCD touch screen  212  facility. The “L” button  211   b  and the “R” button  211   c  indicating left and right directions respectively are used to select the location  401  for the placement of John&#39;s image within the second image of the group of John&#39;s friends. Pressing the “L” button  211   b  indicates that the first image of John is to be placed to the left of his group of friends and pressing the “R” button  211   c  indicates that the first image of John is to be placed to the right of his group of friends. This enables John to be in the image with his friends even though he is not physically present with his group of friends at the moment of capturing the image. The imaging apparatus  200  also saves John the hassle of finding a stranger to capture the image for him or abandoning the imaging apparatus  200  for using a self timer option. John thus protects his imaging apparatus  200  from theft by being in constant possession of the imaging apparatus  200 . 
     John also has the option of inserting his image as a signature in a captured image using the “S” button  211   d  on the image capture device  201 . Consider an example where John captures an image of a rose. John wishes to send the captured image of the rose to his mother. John wants his mother to know that he captured the image for her. John presses the “S” button  211   d  on his digital camera and the image integration software application  213  inserts a small image of John of the size of a postage stamp in a selected location  401  on the captured image of the rose. John uses the “L” button  211   b  and the “R” button  211   c  on the image capture device  201  to place the image of John in the bottom left or bottom right of the captured image of the rose respectively. Pressing the “L” button  211   b  or “R” button  211   c  on the image capture device  201  moves the inserted operator&#39;s image in a general left or right direction respectively, thereby allowing the operator to select the location  401  of the operator&#39;s image on the captured image. Alternatively, the image integration software application  213  automatically inserts John&#39;s image in the bottom left or bottom right corner of the image of the rose. 
     Consider another example of John on a trip with his family. John wishes to take a picture of his family and himself in front of the capitol building. However, John is reluctant to ask a stranger to click the picture as the stranger might not be a reliable person for handing over a digital camera. Additionally, John is apprehensive of not communicating effectively with the stranger. Alternatively, John has to place the digital camera at a suitable distance to focus on the family in front of the capitol building and activate a self timer for a certain period of time, for example, 10 seconds. John then has to return to the location where his family is before completion of 10 seconds to be present in the picture with his family. However, by using the imaging apparatus  200  disclosed herein, John need not ask the stranger, or activate the self timer to take the picture. John presses one of the capture control buttons  205  on the imaging apparatus  200  to capture both the first and second images simultaneously. The image integration software application  213  then proportionately places a first image of John at the location  401  selected by John within the second image of his family. 
     Another use of the “Me-N-2” button  211   a  is illustrated in the following example. Consider a situation where John wishes to capture an image of himself with another person, for example, his wife. With a conventional digital camera, John has to reverse the digital camera and extend his arm holding the digital camera as far as he can to capture the image while making sure both he and his wife are within the range of the second lens  204 . However, with the imaging apparatus  200 , John presses the “R-Len” button  211   f  to enable the use of the first lens  203 . The LCD screen on the reverse of the camera is used to properly line oneself with the background for capturing the image. Also, John ensures that both he and his wife are included within the range of the first lens  203  by viewing the LCD screen and adjusting the camera position to capture the image. John then presses one of the capture control buttons  205 , for example, a click button to capture the image. The first flash unit  206  provides necessary illumination for capturing their image. Thus, a clear image is captured without the possibility of the captured image being crooked or John and his wife being out of range. 
     Consider another example where John is at the Grand Canyon with a multiple lens cell phone comprising the image integration software application  213  disclosed herein. John calls his mother to show her the beauty of the canyon and presses the signature “S” button  211   d  on the cell phone in order to show his mother what he is looking at and to allow her to see him talking to her at the same time. When John presses the “S” button  211   d  on the cell phone, the signature module  213   d  of the image integration software application  213  instructs the lens activation module  213   a  to activate the first lens  203  for filming John while he is talking to his mother and to activate the second lens  204  for filming the Grand Canyon. When the “S” button  211   d  is pressed, the signature module  213   d  inserts John&#39;s recording into the recording of the Grand Canyon, as a signature on the display screen  212  or  301 . The cell phone transmits the composite recording to John&#39;s mother via a communication network. John&#39;s mother will therefore be able to view the recording of the Grand Canyon along with John&#39;s recording as a signature in, for example, the bottom right hand corner of her display screen. The majority of the display screen will display the beauty of the Grand Canyon John is viewing while the bottom right hand corner will display John talking to his mother. As John films the Grand Canyon, he is connected by cell phone to his mother and her image is on the front bottom of his display screen  212  or  301  via his mother&#39;s phone/camera. 
     Consider another example where John is in a conference call with a client overseas. John may want to show his client documents or images and recordings of a building that he is constructing for the client. John may use the multiple lens cell phone to show the documents or images and recordings and at the same time ask questions. When John presses the “S” button  211   d  on the cell phone, the signature module  213   d  of the image integration software application  213  instructs the lens activation module  213   a  to activate the first lens  203  for recording John while he is talking to his client and to activate the second lens  204  for recording the image of the building. When the “S” button  211   d  is pressed, the signature module  213   d  inserts John&#39;s recording into the recording of the building, as a signature on the display screen  212  or  301 . The cell phone transmits the composite recording to the client overseas via a communication network. John&#39;s client will therefore be able to view the building and see and hear John at the bottom right hand corner of the client&#39;s display screen. The use of this technology makes communication personal and allows clear communication due to visual affects. 
       FIG. 5  exemplarily illustrates a flowchart comprising the steps of capturing an image of an operator using a rear lens  203 , herein referred to as the “first lens”, on the image capture device  201 . The operator activates the first lens  203  using the rear lens “R-Len” button  211   f,  illustrated in  FIGS. 3-4 , to take an image of himself/herself and a friend without having to reverse the imaging apparatus  200 . When the operator presses the “R-Len” button  211   f,  the lens activation module  213   a  activates the first lens  203 . In step  501 , the first image, that is, the image of the operator, is captured. In step  502 , the image integration software application  213  digitizes the first image data. In step  503 , the image integration software application  213  presents the first image data on the display screen  212  or  301 . The first lens  203  is therefore used to capture the image of the operator and the friend without reversing the imaging apparatus  200 . 
       FIG. 6  exemplarily illustrates a flowchart comprising the steps of integrating a first image of an operator into a second image of photograph subjects. The image capture device  201  herein exemplarily referred to as a “camera”, comprising the first lens  203  and the second lens  204  is provided to an operator as exemplarily illustrated in  FIGS. 3-4 . In step  601 , the operator uses the first lens  203  of the camera to capture the operator&#39;s image herein referred to as the “first image”. In step  602 , the operator uses the second lens  204  of the camera to capture an image of a photograph subject herein referred to as the “second image”. In step  603 , the image integration software application  213  provided on the camera digitizes the first image data into pixels. In step  604 , the image integration software application  213  digitizes the second image data into pixels. In step  605 , the image integration software application  213  applies, for example, a face/torso recognition algorithm on the first image. Similarly, in step  606 , the image integration software application  213  applies the face/torso recognition algorithm on the second image. In step  607 , the image integration software application  213  prompts the operator to select a desired location for inserting the operator&#39;s image in the second image. 
     In step  608 , the operator&#39;s image in the first image is reversed from left to right. In step  609 , the image integration software application  213  computes the operator scale factor by comparing the focal distance of the camera to the operator with the focal distance of the camera to the subjects in the second image. In step  610 , the image integration software application  213  identifies pixels from the second image that may be overlaid by pixels from the operator&#39;s image. In step  611 , the image integration software application  213  checks if the pixels from the operator&#39;s image overlay part of a face or torso of the subjects in the second image. In step  612 , if the pixel from the operator&#39;s image overlays part of the face or torso of the subjects in the second image, the image integration software application  213  does not replace the pixel in the second image with the corresponding pixel from the operator&#39;s image. In step  613 , if the pixel from the operator&#39;s image does not overlay part of the face or torso of the subjects in the second image, the image integration software application  213  replaces the pixel in the second image with the corresponding pixel from the operator&#39;s image. After all the pixels from the operator&#39;s image have been processed, in step  614 , the image integration software application  213  renders a composite image comprising the operator&#39;s image within the second image to the operator. 
       FIG. 7  exemplarily illustrates a flowchart comprising the steps of inserting a thumbnail sized first image into a second image, as a signature. As disclosed in the detailed description of  FIG. 6 , in step  601 , the operator uses the first lens  203  of the camera to capture the operator&#39;s image herein referred to as the “first image”. In step  602 , the operator uses the second lens  204  of the camera to capture an image of a photograph subject herein referred to as the “second image”. In step  603 , the image integration software application  213  provided on the camera digitizes the first image data into pixels. In step  604 , the image integration software application  213  digitizes the second image data into pixels. In step  701 , the user identifies location for a thumbnail sized extract on the second image for inserting the thumbnail sized first image. In step  702 , the image integration software application  213  scales the first image to thumbnail dimensions. In step  703 , the image integration software application  213  replaces the pixel in the second image with the corresponding pixel from the first image. After all the pixels from the second image have been processed, in step  704 , the image integration software application  213  renders the composite image comprising the thumbnail sized first image inserted into the second image, to the operator.
