[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0012] As shown in Fig. 1, an electronic device 1 according to this embodiment is used by a user. The user uses the electronic device 1 to capture an image of a subject. The electronic device 1 is, for example, a smartphone. However, the electronic device 1 may be any device that can capture an image of a subject.

[0013] 2, electronic device 1 includes first camera 10, second camera 11, display unit 12, positioning unit 13, storage unit 14, and control unit 15. In this embodiment, electronic device 1 includes two cameras, namely first camera 10 and second camera 11. However, electronic device 1 only needs to include at least one camera.

[0014] The first camera 10 is capable of generating a first image of a subject by capturing an image of the subject. The first camera 10 is, for example, a wide-angle camera. However, the first camera 10 is not limited to a wide-angle camera. The first camera 10 may be any camera, such as an ultra-wide-angle camera or a telephoto camera. The first camera 10 is configured to include an imaging element and a lens unit. The lens unit includes at least one lens. The lens is a multifocal lens. However, the lens may also be a single-focal lens. The first camera 10 has an autofocus function.

[0015] The second camera 11 is capable of capturing an image of a subject at a larger magnification than the first camera 10. The second camera 11 is capable of generating a second image of the subject by capturing an image of the subject at a larger magnification than the first camera 10. The second camera 11 is, for example, a macro camera. However, the second camera 11 is not limited to a macro camera. The second camera 11 may be any camera as long as it is capable of capturing an image of a subject at a larger magnification than the first camera 10. The second camera 11 is configured to include an imaging element and a lens unit. The lens unit includes at least one lens. The lens is a single-focus lens. However, the lens may be a multi-focus lens.

[0016] The shortest shooting distance of second camera 11 is shorter than the shortest shooting distance of first camera 10. The shortest shooting distance is the shortest distance from a subject to a camera that can be photographed by the camera.

[0017] The display unit 12 can display various types of information. The display unit 12 can also accept touch operations. The display unit 12 may be a touch screen display in which a display and a touch screen are integrated. The display is, for example, an LCD (Liquid Crystal Display) or an organic EL (Electro Luminescence) display. The touch screen can detect the position where the user touches the touch screen with a finger or the like. The display unit 12 accepts the touch operation by detecting the position where the user touched.

[0018] The positioning unit 13 can acquire position information of the electronic device 1. The positioning unit 13 includes at least one receiving module compatible with a satellite positioning system. The receiving module is, for example, a receiving module compatible with the GPS (Global Positioning System).

[0019] The storage unit 14 includes at least one semiconductor memory, at least one magnetic memory, at least one optical memory, or a combination of at least two of these. The semiconductor memory is, for example, a random access memory (RAM) or a read-only memory (ROM). The RAM is, for example, a static random access memory (SRAM) or a dynamic random access memory (DRAM). The ROM is, for example, an electrically erasable programmable read-only memory (EEPROM). The storage unit 14 may function as a main storage device, an auxiliary storage device, or a cache memory. The storage unit 14 stores data used in the operation of the electronic device 1 and data obtained by the operation of the electronic device 1.

[0020] The control unit 15 is configured to include at least one processor, at least one dedicated circuit, or a combination of these. The processor is, for example, a general-purpose processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), or a dedicated processor specialized for a specific process. The dedicated circuit is, for example, an FPGA (Field-Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit). The control unit 15 controls each unit of the electronic device 1 and executes processes related to the operation of the electronic device 1.

[0021] Based on a touch operation on display unit 12 while the first image is being displayed, control unit 15 marks a portion of the first image that corresponds to the second image and causes display unit 12 to display the second image. An example of this processing will be described with reference to FIG. 3.

[0022] 3 is a flowchart showing an example of a procedure of a display process according to an embodiment of the present disclosure. When control unit 15 activates first camera 10 based on a user operation, control unit 15 starts the process of step S1.

[0023] In the processing of step S1, after starting up first camera 10, control unit 15 moves the focus of first camera 10 so that it is aligned with the subject. After moving the focus of first camera 10, control unit 15 causes first camera 10 to capture an image of the subject and generate a first image. Control unit 15 may perform capture at any frame rate to generate the first image. Once the first image is generated, control unit 15 causes display unit 12 to display the first image in live view. Live view display refers to the display of an image captured and generated by a camera in real time. For example, as shown in FIG. 4, control unit 15 causes display unit 12 to display first image 20 in live view. A rose is captured as the subject in first image 20.

[0024] In the processing of step S1, the control unit 15 may acquire location information of the electronic device 1 using the positioning unit 13. The control unit 15 may display the location information of the electronic device 1 on the display unit 12 together with the first image. The control unit 15 may superimpose the location information of the electronic device 1 on the first image. For example, in FIG. 4, the control unit 15 displays the location information of the electronic device 1, "DDD Town, CCC Ward, BBB City, AAA Prefecture," together with the first image 20. By displaying the location information of the electronic device 1, the user can easily understand the location where the subject is being photographed. The control unit 15 may increase the transparency of the text of the location information of the electronic device 1 displayed on the display unit 12. In this case, the control unit 15 may increase the transparency of the text of the location information of the electronic device 1 displayed on the display unit 12 more than the transparency of the text of the location information of the electronic device 1 added to the third image described below. Alternatively, to increase the transparency of the text of the location information of the electronic device 1 displayed on the display unit 12, the control unit 15 may set the transparency of the text of the location information of the electronic device 1 displayed on the display unit 12 to a first predetermined value. The first predetermined value may be set taking into consideration the visibility of the first image when the text of the location information of the electronic device 1 is superimposed on the first image. The first predetermined value is, for example, 50%. By increasing the transparency of the text of the location information of the electronic device 1 in this way, when the location information of the electronic device 1 is displayed superimposed on the first image, it is possible to prevent the location information of the electronic device 1 from making the first image difficult to view.

[0025] In the process of step S1, control unit 15 may cause display unit 12 to display information about the current time along with the first image. Control unit 15 may superimpose the information about the current time on the first image. For example, in FIG. 4, control unit 15 causes first image 20 to display the current time in "yy / mm / dd / hh / mm" format. Displaying the current time allows the user to easily understand the time at which the subject is being photographed. Control unit 15 may increase the transparency of the text indicating the current time displayed on display unit 12. In this case, control unit 15 may increase the transparency of the text indicating the current time displayed on display unit 12 to be higher than the transparency of the text indicating the current time added to a third image (described below). Alternatively, to increase the transparency of the text indicating the current time displayed on display unit 12, control unit 15 may set the transparency of the text indicating the current time displayed on display unit 12 to a second predetermined value. The second predetermined value may be set taking into consideration the ease of viewing the first image when the text indicating the current time is superimposed on the first image. The second predetermined value may be the same as or different from the first predetermined value. Increasing the transparency of the current time characters in this manner prevents the current time information from making the first image difficult to see when the current time information is displayed superimposed on the first image. Control unit 15 may update the current time displayed on display unit 12 as appropriate.

[0026] In the processing of step S1, control unit 15 may display an image of a shooting execution button for second camera 11 on display unit 12 while displaying the first image in live view. The image of the shooting execution button for second camera 11 is an image for accepting an execution instruction to generate the second image as a still image as a touch operation. For example, in FIG. 4, control unit 15 displays image 30 of the shooting execution button for second camera 11. However, control unit 15 currently makes it impossible to accept a touch operation from the image of the shooting execution button for second camera 11. Therefore, as shown in FIG. 4, the brightness or luminosity of image 30 of the shooting execution button may be lower than that of other images on display unit 12. The low brightness or luminosity of image 30 of the shooting execution button allows the user to easily understand that a touch operation from image 30 is impossible to accept.

[0027] In the process of step S1, when the control unit 15 displays the first image on the display unit 12, the control unit 15 may display a first notification on the display unit 12. The first notification is a notification that prompts the user to touch a portion of the first image that the user wants to enlarge and photograph. For example, in FIG. 4, the control unit 15 displays the first notification 21. The first notification 21 includes text that reads, "Please touch the portion you want to enlarge and photograph." When the user sees the first notification, the user touches a portion of the first image displayed on the display unit 12 that the user wants to enlarge and photograph using the second camera 11. For example, if the user wants to enlarge and photograph the center of a rose in the first image 20 shown in FIG. 4, the user touches the portion 22 that is the center of the rose.

[0028] In the process of step S2, the control unit 15 accepts a touch operation on the display unit 12 while the first image is being displayed in live view. For example, in FIG.

[0029] In the process of step S3, control unit 15 generates a first image as a still image using first camera 10, triggered by the receipt of a touch operation in the process of step S2. Control unit 15 causes display unit 12 to display the first image generated as a still image. Control unit 15 marks the portion of the first image displayed on display unit 12 where the touch operation was received in the process of step S2. For example, as shown in FIG. 5, control unit 15 causes display unit 12 to display first image 23 with a frame 24 added. First image 23 is a still image. Frame 24 corresponds to portion 22 shown in FIG. 4.

[0030] The first image generated as a still image in the process of step S3 is set as the background of the third image in the process of step S7 described below. Therefore, control unit 15 may display a second notification on display unit 12 to notify the user that the background has been set. Furthermore, in the process of step S4 described below, control unit 15 activates second camera 11. Therefore, the second notification may notify the user that the background has been set and that second camera 11 will be activated. For example, in FIG. 5 , control unit 15 displays second notification 25 on display unit 12. Second notification 25 includes the text "Background set. Micro camera will be activated." By viewing the second notification, the user can know that the first image displayed as a still image on display unit 12 has been set as the background of the third image described below. Furthermore, by viewing the second notification, the user can know that second camera 11 will be activated.

[0031] In the processing of step S4, control unit 15 stops first camera 10 and starts second camera 11. After starting second camera 11, control unit 15 causes second camera 11 to generate a second image. Control unit 15 causes display unit 12 to display the generated second image in live view. Control unit 15 may cause display unit 12 to display the second image superimposed on the first image. For example, as shown in FIG. 6, control unit 15 causes display unit 12 to display second image 26 in live view. Control unit 15 also causes display unit 12 to display the second image 26 superimposed on the first image 23. In FIG. 6, control unit 15 causes second image 26 to be displayed at the bottom left as viewed from the front of display unit 12. Control unit 15 may cause the size of second image 26 to be smaller than the size of first image 23.

[0032] In the processing of step S4, the control unit 15 may adjust at least one of the position and size of the second image on the display unit 12 based on a touch operation on the display unit 12 while the second image is being displayed in live view. Therefore, when the control unit 15 displays the second image on the display unit 12, the control unit 15 may cause the display unit 12 to display a third notification informing the user that at least one of the position and size of the second image can be adjusted. The control unit 15 may also cause the display unit 12 to display a third notification informing the user that at least one of the position and size of the second image can be adjusted and that the second image is being displayed on the display unit 12. For example, in FIG. 6 , both the position and size of the second image can be adjusted. Therefore, the control unit 15 displays a third notification 27 on the display unit 12. The third notification includes text stating, "An image is being displayed in a small window. You can adjust the position and size by touching the small window." The user can learn by viewing the third notification that at least one of the position and size of the second image can be adjusted. The user touches the display unit 12 when he or she wants to adjust the position of the second image or the like.

[0033] In the process of step S4, after starting up second camera 11, control unit 15 may make second camera 11 ready to accept a touch operation from image 30 of the shooting execution button. For example, as shown in Fig. 6, control unit 15 may increase the brightness of image 30 of the shooting execution button more than the brightness of image 30 shown in Fig. 4. By increasing the brightness of image 30 of the shooting execution button, the user can easily understand that the image 30 is ready to accept a touch operation.

[0034] In the processing of step S4, when control unit 15 causes display unit 12 to display the first image, which is the generated still image, it may cause display unit 12 to display the image of a back button. The image of the back button is an image for accepting a touch operation to return to the processing of displaying the first image in live view, i.e., the processing of step S1. By returning to the processing of displaying the first image in live view, the user can regenerate the first image, which is a still image to be set as the background of the third image. For example, in FIG. 6, control unit 15 causes display unit 12 to display image 31 of a back button. When control unit 15 accepts a touch operation on image 31 of the back button, it may return to the processing of step S1.

[0035] After the process of step S4, the user brings electronic device 1 closer to the rose in order to photograph the center of the rose with second camera 11. The user brings electronic device 1 closer to the rose until the focus of second camera 11 is set on the center of the rose. When the focus of second camera 11 is set on the center of the rose, the user touches image 30 of the photographing execution button of second camera 11 as shown in FIG.

[0036] In the processing of step S5, control unit 15 accepts a touch operation on the image of the shooting execution button of second camera 11. Receipt of this touch operation triggers control unit 15 to generate a second image as a still image by second camera 11 (step S6). For example, control unit 15 uses second camera 11 to generate second image 29, which is a still image as shown in Fig. 7 described below.

[0037] In the process of step S7, control unit 15 generates a third image by superimposing the second image on the first image. Control unit 15 generates a third image by superimposing the second image generated as a still image in the process of step S6 on the first image generated as a still image in the process of step S3. Control unit 15 may use the first image as the background of the third image by superimposing the second image on the first image. Control unit 15 may display the generated third image on display unit 12. For example, as shown in FIG. 7, control unit 15 displays the generated third image 28 on display unit 12. In third image 28, second image 29, which is a still image, is superimposed on first image 23, which is a still image.

[0038] In the process of step S7, the control unit 15 marks the portion of the first image that corresponds to the second image in the third image. For example, in Fig. 7, the control unit 15 marks the third image 28 with a frame 24.

[0039] In the process of step S7, the control unit 15 may add the location information of the electronic device 1 acquired in the process of step S1 to the third image. The control unit 15 may also add information about the current time to the third image. For example, in FIG. 7, the control unit 15 adds the location information of the electronic device 1, "DDD Town, CCC Ward, BBB City, AAA Prefecture," and the current time in "yy / mm / dd / hh / mm," to the third image 28. The control unit 15 may lower the transparency of the text indicating the location information of the electronic device 1 and the current time added to the third image below the transparency of the text indicating the location information of the electronic device 1 and the current time displayed on the display unit 12 in the process of step S1. Alternatively, the control unit 15 may set the transparency of the text indicating the location information of the electronic device 1 and the current time added to the third image to a third predetermined value. The third predetermined value may be set taking into consideration the visibility of the text indicating the location information of the electronic device 1 and the current time when the text indicating the location information of the electronic device 1 and the current time is superimposed on the third image. The control unit 15 may make the characters of the location information and the current time of the electronic device 1 that are added to the third image opaque. When the characters are opaque, the transparency of the characters may be 0%.

[0040] After the process of step S7, that is, after the third image is generated, the control unit 15 stores the third image in the storage unit .

[0041] In the processing of steps S1 to S7, the control unit 15 may cause the display unit 12 to display an image 32 for accepting a user operation, as shown in FIGS. 4 to 6. The control unit 15 may prevent the display unit 12 from displaying the first to third notifications in response to the user operation accepted from the image 32. As the user becomes accustomed to operating the electronic device 1, the user may find the first notification and the like annoying. In this case, by preventing the display unit 12 from displaying the first to third notifications in response to the user operation, the possibility that the user will feel annoyed can be reduced.

[0042] As described above, in the electronic device 1 according to the present embodiment, based on a touch operation on the display unit 12 while the first image is being displayed, the control unit 15 marks a portion of the first image corresponding to the second image and causes the display unit 12 to display the second image. By marking a portion of the first image corresponding to the second image, the user can quickly determine which portion of the subject included in the first image is an enlarged image of the second image. For example, the user can quickly determine whether the second image 29 shown in FIG. 7 is an enlarged image of the frame 24 of the subject included in the first image 23. Therefore, according to the present embodiment, the technology for displaying two images can be improved in terms of user convenience.

[0043] Furthermore, in this embodiment, when the first image is displayed on the display unit 12, the control unit 15 may also display a first notification on the display unit 12. By displaying such a first notification on the display unit 12, the user can quickly touch the part of the first image displayed on the display unit 12 that the user wishes to zoom in on, even if the user is not familiar with using the electronic device 1.

[0044] Furthermore, in this embodiment, control unit 15 may cause display unit 12 to display location information of electronic device 1 together with the first image. By displaying the location information of electronic device 1, the user can easily understand the location where the subject is being photographed, as described above. Furthermore, control unit 15 may increase the transparency of the text of the location information of electronic device 1 displayed on display unit 12. By increasing the transparency of the text of the location information of electronic device 1, it is possible to prevent the location information of electronic device 1 from making the first image difficult to see, as described above.

[0045] In the present embodiment, control unit 15 may also cause display unit 12 to display information about the current time together with the first image. By displaying the current time, the user can easily grasp the time at which the subject is being photographed, as described above. Control unit 15 may also increase the transparency of the characters indicating the current time displayed on display unit 12. By increasing the transparency of the characters indicating the current time, it is possible to prevent the information about the current time from making the first image difficult to see, as described above.

[0046] Furthermore, the electronic device 1 according to the present embodiment may include a first camera 10 capable of generating a first image and a second camera 11 capable of generating a second image. By including the first camera 10 and the second camera 11 in the electronic device 1, the specifications of the first camera 10 that generates the first image and the specifications of the second camera that generates the second image can be determined separately. This configuration allows the electronic device 1 to generate a second image in which a portion of a subject included in the first image is more enlarged. For example, by using the second camera 11 with a shorter minimum shooting distance, a second image in which a portion of a subject included in the first image is more enlarged can be generated. Furthermore, by using a zoom function, the first image and the second image can also be generated using a single camera. However, when the first image and the second image are generated simultaneously using a single camera, the first image and the second image can only be generated with an angle of view centered on that camera. In the present embodiment, by using the second camera 11 separate from the first camera 10, the user can generate the second image at any position (angle of view).

[0047] Furthermore, in this embodiment, after starting up the first camera 10, the control unit 15 may cause the display unit 12 to display the first image in live view. By displaying the first image in live view on the display unit 12, the user can check the first image in real time via the display unit 12. Furthermore, the control unit 15 may cause the second camera 11 to be started up when the control unit 15 receives a touch operation on the display unit 12 while the first image is being displayed in live view. After starting up the second camera 11, the control unit 15 may cause the display unit 12 to display the second image in live view. By displaying the second image in live view on the display unit 12, the user can check the second image in real time via the display unit 12.

[0048] Furthermore, in this embodiment, control unit 15 may cause display unit 12, while displaying the first image in live view, to display an image of a shooting execution button for second camera 11. However, control unit 15 may cause display unit 12 to be in a state where touch operations from the image of the shooting execution button cannot be accepted at this point. By causing touch operations from the image of the shooting execution button to be in a state where they cannot be accepted, it is possible to prevent second camera 11 from being started up, for example, by the user accidentally touching the image of the shooting execution button while the first image is being displayed in live view.

[0049] Furthermore, in this embodiment, when control unit 15 receives a touch operation on display unit 12 while the first image is being displayed in live view, control unit 15 may cause display unit 12 to display a second notification. By viewing the second notification, the user can know that the first image displayed as a still image on display unit 12 has been set as the background of the third image. Furthermore, by viewing the second notification, the user can know that second camera 11 will be activated.

[0050] Furthermore, in this embodiment, when control unit 15 causes display unit 12 to display the first image generated as a still image, control unit 15 may cause display unit 12 to display an image of a back button for accepting a touch operation to return to the process of displaying the first image in live view. When control unit 15 accepts a touch operation on the image of the back button, control unit 15 may return to the process of displaying the first image in live view. With this configuration, if the user does not want to set the first image displayed as a still image on display unit 12 as the background of the third image, the user can return to the process of displaying the first image in live view. By returning to the process of displaying the first image in live view, the user can regenerate the first image as a still image to be set as the background of the third image.

[0051] Furthermore, in this embodiment, when the second image is displayed on the display unit 12, the control unit 15 may cause a third notification to be displayed on the display unit 12. The control unit 15 may adjust the position or size of the second image on the display unit 12 based on a touch operation on the display unit 12 while the second image is being displayed in live view. With this configuration, the user can easily adjust the position or size of the second image.

[0052] In this embodiment, the control unit 15 may generate a third image by superimposing the second image on the first image. The control unit 15 may mark the portion of the first image that corresponds to the second image in the generated third image. By generating such a third image, the user can easily check the subject later.

[0053] (Other embodiments) In another embodiment, the control unit 15 executes a correction process to correct the position of a mark added to the first image or the third image. In this correction process, after the second camera 11 is started, the control unit 15 executes an image recognition process on the first image and the second image to estimate a portion of the first image that corresponds to the second image. The image recognition process may use any algorithm. For example, the image recognition process may be an image recognition process using machine learning or an image recognition process using pattern matching, etc. The control unit 15 corrects the position of the mark added to the first image or the third image based on the estimated portion that corresponds to the second image. For example, the control unit 15 may correct the position of the mark added to the first image or the third image by moving the position of the mark added to the first image or the third image to the estimated portion that corresponds to the second image. The control unit 15 may execute the correction process at any timing after the start of the second camera 11. In other words, the control unit 15 may execute the correction process at any timing after the processing of step S4.

[0054] For example, the configuration shown in FIG. 8 corresponds to the configuration after the processing of step S4. In the configuration shown in FIG. 8, control unit 15 causes display unit 12 to display first image 40, which is a still image. Control unit 15 also causes display unit 12 to display second image 41 in live view. Control unit 15 marks the portion where the touch operation was accepted in the processing of step S2, and adds a frame 42 to first image 40. Here, control unit 15 performs image recognition processing on first image 40 and second image 41, and thereby estimates that the portion of first image 40 that corresponds to second image 41 is portion 43. Control unit 15 corrects the position of frame 42 by moving the position of frame 42 to the position of portion 43.

[0055] As described above, the user touches a portion of the first image displayed on display unit 12 that the user wishes to enlarge and photograph using second camera 11. However, as the user approaches the subject to generate the second image, the portion of the first image that the user touched may differ from the portion that the user actually enlarges and photographs using second camera 11. Even in such a case, the position of the mark added to the first image or the third image is corrected, so that the user can correctly identify the portion of the first image or the third image that corresponds to the second image.

[0056] Other configurations and effects of the electronic device 1 according to the other embodiments are the same as or similar to the configurations and effects of the electronic device 1 according to the above-described embodiments.

[0057] (Still another embodiment) In yet another embodiment, control unit 15 generates an assumed image to be used as the second image based on a portion of display unit 12 displaying the first image where a touch operation has been received. For example, control unit 15 detects a portion of the first image where a touch operation has been received in the processing of step S2. Control unit 15 generates the assumed image by enlarging the image of the portion where the touch operation has been received using the zoom function of first camera 10. Control unit 15 may generate the assumed image in the processing of step S3.

[0058] After second camera 11 is started, control unit 15 compares the generated assumed image with the second image captured by second camera 11. Based on the comparison result between the assumed image and the second image, control unit 15 determines whether the shooting location of the second image is shifted. Here, "the shooting location of the second image is shifted" means that the shooting location is shifted from the shooting location where the subject is captured by second camera 11 in order to generate the second image, which is an enlarged version of the portion of the first image for which the touch operation was accepted in the processing of step S2. If control unit 15 determines that the shooting location of the second image is shifted, it causes display unit 12 to display a fourth notification notifying the user that the shooting location of the second image is shifted.

[0059] The user may wish to generate a second image by enlarging the touched portion of the first image. When the control unit 15 determines that the shooting location of the second image is misaligned, the control unit 15 causes the display unit 12 to display a fourth notification notifying the user that the shooting location of the second image is misaligned. This fourth notification allows the user to easily determine whether the shooting location of the second image is misaligned. As a result, the user can generate a second image by enlarging the touched portion of the first image.

[0060] After starting up second camera 11, control unit 15 may display the second image and the assumed image on display unit 12. With this configuration, the user can easily check whether the shooting location of the second image is misaligned by comparing the second image with the assumed image.

[0061] Other configurations and effects of the electronic device 1 according to the other embodiments are the same as or similar to the configurations and effects of the electronic device 1 according to the above-described embodiments.

[0064] The second sensor unit 17 is capable of detecting the attitude of the electronic device 1. The second sensor unit 17 includes, for example, at least one of a three-axis acceleration sensor, a three-axis gyro sensor, a three-axis angular velocity sensor, an inertial measurement unit (IMU), and the like.

[0065] In yet another embodiment, the control unit 15 executes a correction process to correct the position of the mark added to the first image or the third image. After starting the second camera 11, the control unit 15 measures the distance from the electronic device 1 to the subject using the first sensor unit 16 and detects the attitude of the electronic device 1 using the second sensor unit 17. The control unit 15 corrects the position of the mark added to the first image or the third image based on the measured distance from the electronic device 1 to the subject and the detected attitude of the electronic device 1. The control unit 15 may execute the correction process at any timing after starting the second camera 11. In other words, the control unit 15 may execute the correction process at any timing after the processing of step S4. By correcting the position of the mark added to the first image or the third image, the user can correctly identify the portion of the first image or the third image that corresponds to the second image, in the same or similar manner as in the other embodiments described above.

[0066] In still another embodiment, control unit 15 may generate guide information. The guide information is guide information for generating a second image by enlarging a portion of the first image where a touch operation was accepted in the processing of step S2. After starting second camera 11, control unit 15 measures the distance from electronic device 1 to the subject using first sensor unit 16 and detects the attitude of electronic device 1 using second sensor unit 17. Control unit 15 generates the guide information based on the portion where a touch operation was accepted on display unit 12 displaying the first image in the processing of step S2, the measured distance to the subject, and the detected attitude of electronic device 1. The guide information includes information on the distance to the subject and information on the direction in which second camera 11 should be moved relative to the subject. Control unit 15 displays the generated guide information on display unit 12 during live view display of the second image. Control unit 15 may update the guide information as appropriate during live view display of the second image and display the updated guide information on display unit 12. Such guide information allows the user to quickly generate a second image that is an enlarged version of the touched portion of the first image.
