The elements of the dome may be formed of a plastic material. The optical system 140 is moved by extending the elements of the dome 150 to a position between the supporting device 120 and the film processing unit 110. At this position the optical system may change the size of the projected image in comparison to the original image. In particular, the optical systems maps the image from the screen of the portable electronic apparatus onto the film frame of the instant photo film with a larger size than the size of the original image displayed on the screen of the electronic apparatus. The optical system enables to increase an image shown at the screen of the portable electronic apparatus onto the film frame of the analogue instant photo film.

The upper part of the instant camera comprising the

supporting device 120, the optical system 140 and the dome 150 may be coupled to the lower portion of the instant camera comprising the shutter device 130 and the film processing unit 110 by a mechanical adapter 160. The mechanical adapter 160 may include the shutter device 130. Figure 2 shows an embodiment of the instant camera 100 to take an instant photo of an image of a screen of a portable electronic apparatus in the closed state. The elements 151, 155 of the dome are telescoped so that the dome 150 and the optical system 140 disappears in the housing of the film processing unit 110. In the closed state the supporting device 120 is disposed on the upper surface of the housing of the film processing unit. Figure 3 shows an embodiment of the instant camera 100 to take an instant photo of an image of a screen of a portable electronic apparatus. According to the embodiment of Figure 3 the dome 150 is formed as a collapsible bellows. The optical system 140 is affixed to the bellows such that the optical system 140 is moved in the vertical direction far away from the film cassette 200 when the dome is drawn apart. The movement of the optical system is comparable with the

movement of the optical system according to the embodiment as shown in Figure 1.

According to the embodiment of the instant camera illustrated in Figure 3, the shutter device 130 is disposed below or above the optical system 140. The shutter device may, for example, be disposed at the side of the optical system which is close to the film processing unit 110 or at a side of the optical system which is close to the supporting device 120. The shutter device 130 may be configured as a ring-shaped or rectangular-shaped closure which is disposed above an upper lens of the optical system, wherein the upper lens is

directed towards the recess 122 of the supporting device 120, or below a lower lens of the optical system, wherein the lower lens is directed towards the film processing unit 110. The process of opening and closing the shutter device may be performed automatically by a motor. The embodiment of the shutter device 130 as shown in Figure 3 may also be provided with the embodiment of the camera shown in Figure 1.

Figures 4A, 4B and 4C show an embodiment of the supporting device 120 which is arranged to be coupled to the dome 150. The supporting device 120 comprises an adjustment device 123 to adapt the size of the supporting area 121 to portable electronic apparatus of different size such that the screen of a portable electronic apparatus is placed in the center above the recess 122 when the electronic apparatus is fixed on the supporting area 121 by the adjustment device 123. The adjustment device 123 may be arranged as a sliding element having a stop element 124. The sliding element may be

horizontally moved to increase or decrease the supporting area 121. Figure 4B shows the supporting device 120 in which the adjustment device 123 is moved such that the supporting area 121 is adjusted to the size of an electronic apparatus to be placed onto the supporting area. The recess 122 is located so that the screen of the portable electronic

apparatus is disposed above the recess when the apparatus is placed onto the supporting area 121. Figure 4C shows an electronic apparatus 400 configured as a smart phone which is placed onto the supporting area 121. The sliding element 123 is moved such that the electronic apparatus is fixed and centered on the supporting area between the elevated rim of the supporting area and the stopper element 124. Figure 5 shows an embodiment of a film cassette 200 including an instant photo film 300. The film cassette 200 comprises a housing 210 including a spring element 220 which is mounted on a base plate 230. A plurality of stacked film frames 310 is disposed on the spring element 220. The spring element exerts a pressure on the stacked film frames so that after removing the most upper film frame from the stack for

ejecting the adjacent film frame in the stack is pushed up and may be exposed. The instant camera 100 may be used with different kinds of instant photo films. A first instant film type, such as a Polaroid Integral film, is exposed from the front side and thus requires mirroring of an image displayed on the screen of the portable electronic apparatus. Each frame 310 of the first instant film type comprises a positive 311, a negative 312 and a mask 313. The positive 311 is disposed below the negative 312. That means that the positive 311 is disposed between the negative 312 and the mask 313. The negative 312 is directly positioned below the shutter device 130 so that during an exposure process light from the screen of the portable electronic apparatus first illuminates the negative 312.

The instant camera 100 may also be used with a film cassette including a second instant photo film, such as produced, for example, by Kodak or Fuji, which is exposed from the backside and does not require mirroring of an image displayed on the screen of the portable electronic apparatus. The film frames 310 of the second film type in each case comprise a positive 311, a negative 312 and a mask 313. In the case of the second instant film type the negative 312 is disposed between the positive 311 and the mask 313. That means that light emitted from the screen of a portable electronic apparatus which is disposed on the supporting device 120 first illuminates the positive 311. When using an instant photo film of the second type an image displayed on the screen of an electronic apparatus which is placed on the supporting device 120 may be displayed on the screen in an un-mirrored manner.

Figure 6 shows an embodiment of the optical system 140. The optical system comprises an optical lens group including for example four lenses 141, 142, 143 and 144. The optical lenses may be arranged in a housing 145 so that light coming from the illuminated display of the portable electronic apparatus first is diffracted by lens 141 and then one after the other by lens 142, lens 143, and lens 144. The optical lens system is configured so that the image shown on the screen of the electronic apparatus is projected on the photosensitive material of the most upper film frame 310 which is placed in the film cassette which is inserted in film processing unit 110. In particular, the optical system 140 is configured to increase the projected image in relation to the original image on the screen of the portable electronic apparatus which means that the image projected on the film frame of the instant photo film is larger than the original picture displayed on the screen of the electronic apparatus. The optical system 140 is further arranged so that any pixels displayed in the screen of the portable electronic apparatus are not visible for an observer on the photo. Figure 7 shows an embodiment of a software architecture which may be used by the portable electronic apparatus to provide a user with instructions when taking a photo of the screen of the portable electronic apparatus and to control the

illumination of the screen of the portable electronic

apparatus during the process to take the photo.

Figure 7 also shows a portable electronic apparatus 400 which may be configured as a programmable device, such as a digital camera or a smart phone. The portable electronic apparatus 400 comprises a memory 450 in which a plurality of images 410, 411, 412 may be stored. The programmable device 400 further comprises a display 420 to display the images.

The electronic apparatus may comprise a readable storage medium 430 to store a basic function module 1000a and an application module 1000b. The application program 1000b may be an applet for a smart phone or part of a firmware of a digital camera or programmed for other mobile devices. The modules 1000a and 1000b contain one or more programs including instructions which may be executed by a processor 440 of the apparatus 440. The storage medium 430 may be accessed by the processor 440.

The module 1000a comprises basic functions, such as curves for exposure times, film sensitivities of different types of instant photo films, exposure calculation routines, mirroring functions, and step by step instructions as a support for a user. The application module 1000b provides a user interface to select images from which a picture should be taken, a film type inserted in the instant camera and select different operating modes such as a single/multiple exposure mode or a beginner/expert mode. The concept for the application program 1000b is an open architecture. That means that the basic functions provided by the module 1000a may be integrated in the application program 1000b. Program developers can simply include the basic functions provided by the module 1000a in their own application modules 1000b for additional

programmable devices to be extended with an "instant photo development" function.

Figure 8 shows a first embodiment of a method to take an instant photo of an image 410 displayed on the screen 420 of the portable electronic apparatus 400 which is disposed on the supporting device 120 of the instant camera 100. In a first step 1 a user 500 starts the application program 1000b for controlling the process to take an instant photo of the screen 420 and for providing step by step instructions for the user. After the application program 1000b is started a user interface is displayed on the screen 420 to input commands, select mode settings and select images from which a photo should be taken. According to step 2 the user interface outputs a command to select a film type of an analogue instant photo film. The film types may differ in the arrangement of the positive and the negative within the film frame. Furthermore, a user may be asked to select a light-sensitivity of the analogue instant photo film inserted in the instant camera 100. The processor 440 detects the selected film type and the selected light-sensitivity of the analogue instant photo film. In step 3 a command is output by the processor 440 to set an exposure mode. The user may select a single or a multiple exposure mode. If the single exposure mode is selected, one selected image 410 is projected to the film frame 310 of the analogue instant photo film. If the multiple exposure mode is

selected, at least two selected images 410, 411 are projected subsequently to the same film frame 310. The processor 440 detects the selected single or multiple exposure operating mode . In step 4 the processor 440 outputs on the display 420 a command which asks the user to select a beginner or expert mode, i.e. the user may select the kind for outputting commands. When selecting the beginner mode commands are output by voice from the portable electronic apparatus 400. If the expert mode has been selected by a user in step 3, the portable electronic apparatus outputs commands by optical signals such as flashing light signals generated by a flash light of a smart phone or a digital camera. The processor 440 detects the selected mode for outputting commands. In step 5 the processor 440 outputs a command by which the user is asked to select the images 410, 411, 412 from which a photo should be taken. The processor 440 detects the selected images . In step 6 the user starts the actual development process to take an instant photo from the selected pictures. In step 7 the portable electronic apparatus outputs a command by which the user is invited to place the portable electronic

apparatus 400 on the supporting device 120 of the instant camera 100 such that the screen 420 is disposed over the recess 122 and is directed towards the film processing unit 110 of the camera.

After having placed the apparatus 400 on the supporting device 120 in step 8, the processor 440 outputs in step 9 a command by which the user is asked to open the shutter device 130. The selected image or the first image of a sequence of a plurality of selected images is then displayed in the screen 420 of the portable electronic apparatus 400. The selected image 410 is displayed on the screen with a brightness in dependence on the selected light-sensitivity of the analogue instant photo film. Furthermore, the selected image is displayed on the screen in a mirrored or un-mirrored manner in dependence on the selected first and second type of the analogue instant photo film.

After the user manually opens the shutter device 130 in step 10, the film frame 310 of the analogue instant photo film 300 is exposed by the light of the image displayed on the screen of the portable electronic apparatus in step 11. In step 12, after having finished the exposure process, the processor 440 outputs a command to ask the user to close the shutter device 130. After the user has closed the shutter device in step 13, the processor 440 evaluates in step 14 whether the single exposure mode or the multiple exposure mode has been

selected . If the processor 440 establishes that the single exposure mode has been selected, the processor outputs a command to ask the user to press the eject button 114 of the film processing unit 110. After the eject button 114 is actuated the film processing unit 110 starts the development process: A pick of a transporting unit grabs the exposed film frame 310, transports it towards the development rollers 111, pushed it through the development unit and finally ejects the instant photo out of the ejection hole 113. The instant photo will then slowly develop in the palm of the hand of the user.

The user may proceed by taking away the portable electronic apparatus 400 from the supporting device 120 and selecting another image from which the user intends to take the next picture. Due to the closed shutter it is prevented that the light sensitive photo material is overexposed by light entering the apparatus from the top when the user removes the portable electronic apparatus for selecting another image. In addition, the upper lens 141 of the optical system may be protected by a closure which also prevents any light incident inside the area of the dome 150 between the optical system 140 and the film processing unit 110. If the processor 440 establishes in step 14 that the multiple exposure process has been selected the steps 5 to 14 are repeated until the film frame 310 is exposed with all

selected images. Figure 9 shows another embodiment of the method to take an instant photo of an image displayed on the screen of the portable electronic apparatus. The steps shown in Figure 9 are identical to the steps shown in Figure 8 except for the steps 9, 10 and 12, 13 which are replaced by steps 19 and 20. According to the second embodiment of the method to take an instant photo the complete process is controlled

automatically without the need of any interaction by the user in respect of opening or closing the shutter device 130.

According to the second embodiment of the method to take an instant photo the shutter device 130 is automatically

operated. The manually operated shutter device 130 used in the first embodiment of the method to take an instant photo may be replaced, for example, by a ring-shaped shutter device which is disposed below lens 144 of the optical system 140. The portable electronic apparatus 400 may comprise an

interface 460 to generate a control signal SI and S2. The interface 460 may be arranged as a Bluetooth interface to transmit the Bluetooth signals SI and S2. The camera 100 may comprise an interface 170 to receive the control signals SI and S2. The interface 170 may be arranged as a Bluetooth interface to receive the Bluetooth signals. The interface 460 and the interface 170 may also be arranged as a WiFi or serial interface.

In step 19 the portable electronic device 400 generates the control signal SI. The interface 170 of the camera 100 receives control signal SI. The motor of the shutter device 130 is controlled by the control signal SI such that in step 19, the shutter device is opened so that the photosensitive material of the film frame 310 in the film cassette 200 may be exposed. In step 20 the processor 440 generates the control signal S2 which is radiated from interface 450 of the apparatus 400 and received by interface 170 of the camera 100. The control signal S2 causes the motor of the shutter device 130 to close the shutter device 130 so that the film frame 310 in the film cassette 200 is prevented from being exposed by any disturbing light.
