[0001] The present disclosure relates to an information processing device, an information processing method, and a program. Background Art

[0002] In recent years, portable information processing devices such as smartphones and tablet terminals are becoming increasingly popular. In addition, the performance of camera functions in these portable information processing devices is also rapidly developing, and for example, not only models including external cameras and built-in cameras, but also models including external cameras with multiple lenses of different focal lengths are expanding.

[0007] Technical issues

[0008] However, the above conventional technology still has room for further improvement in terms of improving convenience when using photography apps.

[0009] For example, although the above-mentioned conventional technology expands each function to expand the range in which the user can participate in image quality, in the case where a plurality of lenses of different focal lengths are provided, the expansion of the function is insufficient when the zoom function is used.

[0010] Note that such a problem is not limited to the case of using a photography app, but is a problem common to apps that generally operate optical system devices that require manipulation of focal length.

[0011] Therefore, the present disclosure proposes an information processing apparatus, an information processing method, and a program, which can further improve the convenience when using an operation app for an optical system device.

[0012] Solution to the problem

[0013] In order to solve the above-mentioned problem, one aspect of an information processing device according to the present disclosure includes: an app execution unit, which is capable of executing an operation app of an optical system device including multiple lenses of different focal lengths, wherein the multiple lenses of different focal lengths include a zoom lens; and a display control unit, which causes the display unit to display a first user interface, which clearly indicates the optical zoom range of the zoom lens, which is used for the zoom function of the lens included in the operation app. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] <<1. Smartphone Configuration>>

[0046] <1-1. Schematic configuration of smartphone>

[0047] Figure 1 is a schematic diagram of a smartphone 10 according to an embodiment of the present disclosure (part 1). In addition, Figure 2 is a schematic diagram of a smartphone 10 according to an embodiment of the present disclosure (part 2). Note that Figure 1 The configuration of the front surface side of the smartphone 10 is shown. Figure 2 The configuration on the back side of the smartphone 10 is shown. Figure 3 It is an explanatory diagram of the first lens 17-U, the second lens 17-W, and the third lens 17-T.

[0048] The smartphone 10 is a portable information processing device having a camera function. Figure 1 As shown, the touch screen TS is provided on the front surface of the smartphone 10. The touch screen TS is a device formed by integrating a touch panel and a display. The touch screen TS detects a touch operation of a user. As a detection method of the touch screen TS, known methods such as a capacitance method, a resistance film method, a surface acoustic wave method (or an ultrasonic method), an infrared method, an electromagnetic induction method, and a load detection method are used.

[0049] The touch screen TS has a rectangular shape. For example, at one end in the longitudinal direction of the smartphone 10, a camera lens 16 for a built-in camera and an earpiece 15 are provided. A speaker is provided to the earpiece 15. Although not shown, for example, at the other end of the smartphone 10, a microphone including a microphone is provided.

[0050] For example, on the side surface of the smartphone 10 along the long side of the touch screen TS, a volume key 11, a fingerprint sensor 12, a power key 13, and a camera key 14 are provided. The volume key 11 is a hardware key for adjusting the volume. The fingerprint sensor 12 is a device for reading fingerprints. The power key 13 is a hardware key for turning the power on / off. The camera key 14 is a hardware key for activating a camera app. The camera key 14 is used as a shutter when taking pictures. For example, the camera key 14 is set at a position closer to the microphone (on the opposite side of the earpiece 15 side) than the center part of the side surface of the smartphone 10.

[0051] In addition, if Figure 2 As shown, a plurality of camera lenses 17 with different focal lengths are arranged on the back of the smart phone 10. The camera lens 17 is a camera lens for an external camera. Figure 2In the example of FIG. 1 , the camera lens 17 is provided as a plurality of camera lenses 17 , for example, a first lens 17 -U, a second lens 17 -W, and a third lens 17 -T.

[0052] Here, if Figure 3 As shown, for example, the first lens 17-U is an ultra-wide-angle lens with a focal length of 16 mm (millimeter). In addition, for example, the second lens 17-W is a standard wide-angle lens with a focal length of 24 mm. In addition, for example, the third lens 17-T is a telephoto lens with a focal length of 85 mm to 125 mm. That is, the third lens 17-T is an optical zoom lens that can change the focal length within the range of 85 mm to 125 mm.

[0053] The smartphone 10 switches the optical zoom of the camera function by selecting these first lens 17-U, second lens 17-W, and third lens 17-T via the camera app. When the first lens 17-U is selected, the smartphone 10 switches the optical zoom to 16mm. In addition, when the second lens 17-W is selected, the smartphone 10 switches the optical zoom to 24mm. In addition, when the third lens 17-T is selected, the smartphone 10 can change the magnification within the range of 85mm to 125mm through the optical zoom. In this case, "85mm to 125mm" corresponds to the "optical zoom interval" described later.

[0054] In addition, when the first lens 17-U is selected, the smartphone 10 can change the magnification within the range of 16mm to 48mm by digital zoom. In addition, when the second lens 17-W is selected, the smartphone 10 can change the magnification within the range of 24mm to 85mm by digital zoom. In addition, when the third lens 17-T is selected, the smartphone 10 can change the magnification within the range of 125mm to 375mm by digital zoom.

[0055] Note, for example, Figure 3 The "x0.7" shown in is a magnification conversion value at each distance when the focal length of 24 mm is 1.0 times. In the following description, the setting value of the zoom function on the user interface (UI) of the camera app may be represented by this magnification conversion value.

[0056] By the way, according to the zoom function of the conventional camera app, when the user wants to change the magnification, the user needs to select the camera lens 17 according to the desired magnification each time. In addition, when the user wants to change the magnification beyond the settable range of the selected camera lens 17, the user needs to select a camera lens 17 having the second largest or second smallest focal length after the currently set camera lens 17.

[0057] This operation is similar to that of a normal digital camera. Therefore, such an operation has the advantage that the user can perform a zoom operation in the same manner as a digital camera. However, according to such an operation, the user needs to select the camera lens 17 that matches the desired magnification each time as described above.

[0058] Furthermore, the UI of the zoom function of the conventional camera app also has a problem that, in the case where the camera lens 17 includes a zoom lens like the third lens 17 -T, it is difficult for the user to grasp the range that can be set by the optical zoom.

[0059] Therefore, according to the information processing method of the embodiment of the present disclosure, in the case where a plurality of camera lenses 17 with different focal lengths including a zoom lens are provided, a UI (corresponding to an example of a “first user interface”) is presented to the user, and the UI clearly indicates the optical zoom interval (85 mm to 125 mm). In addition, according to the information processing method of the embodiment of the present disclosure, a UI (corresponding to an example of a “second user interface”) is presented to the user that continuously indicates the range from the minimum magnification to the maximum magnification that can be set for all the plurality of camera lenses 17. This will be referred to later. Figure 3 and subsequent drawings describe specific examples thereof.

[0060] This description returns to Figure 2 The flash 18 and the red, green, blue, transparent infrared (RGBC-IR) sensor 19 are provided near the camera lens 17. The flash 18 is a device that is turned on to brightly illuminate the photographic target when photographing. The RGBC-IR sensor 19 is a device that detects the composition of the light source in the photographic environment when photographing. For example, the RGBC-IR sensor 19 acquires infrared information about the surroundings of the smartphone 10 and specifies a light source environment such as an outdoor environment, an incandescent lamp, or a fluorescent lamp.

[0061] <1-2. Functional configuration of smartphones>

[0062] Next, the functional configuration of the smartphone 10 will be described. Figure 4 is a block diagram showing a configuration example of the smartphone 10 according to an embodiment of the present disclosure. Note that Figure 4 Only components necessary for describing the features of the embodiments of the present disclosure are shown, and descriptions of general components are omitted.

[0063] In other words, Figure 4 Each component shown is conceptual in function and does not necessarily need to be physically configured as shown. For example, the specific mode of distribution and integration of each block is not limited to the mode shown, and all or part of it can be functionally or physically distributed and integrated in any unit according to various loads, usage conditions, etc.

[0064] In addition, reference Figure 4 The description may be simplified or omitted for components that have already been described.

[0065] like Figure 4 As shown, the smartphone 10 includes a camera 101 , a focal length variable mechanism 102 , an inertial sensor unit 103 , a communication unit 104 , an operation unit 105 , a display unit 106 , a storage unit 107 , and a control unit 108 .

[0066] The camera 101 is a camera mounted on the smartphone 10, and includes the above-mentioned camera lenses 16 and 17. The focal length variable mechanism 102 is a mechanism that changes the focal length of the above-mentioned third lens 17-T as a zoom lens within a range of 85 mm to 125 mm.

[0067] The inertial sensor unit 103 includes a G sensor and a gyro sensor. The inertial sensor unit 103 measures the angular velocity and acceleration of the smartphone 10. The control unit 108, which will be described later, uses the measurement data to calculate the posture / direction, velocity, position, etc. of the smartphone 10 in real time.

[0068] The communication unit 104 is implemented as a communication module, etc. The communication unit 104 implements communication between the smartphone 10 and an external device other than the smartphone 10 .

[0069] The operation unit 105 is an operation member mounted on the smartphone 10. The display unit 106 is a display member mounted on the smartphone 10.

[0070] Note that the operation unit 105 and the display unit 106 may be integrated into a touch screen TS. Therefore, the operation unit 105 may be a software component, and in an embodiment of the present disclosure, for example, the operation unit 105 may be a graphical user interface (GUI) that a camera app may be operable to display on the display unit 106.

[0071] For example, the storage unit 107 is implemented by a semiconductor memory element such as a random access memory (RAM), a read only memory (ROM), or a flash memory. Figure 4 In the illustrated example, the storage unit 107 stores app information 107a. The app information 107a is information including a program of the camera app, various parameters used during the operation of the camera app, and the like.

[0072] The control unit 108 is a controller and is implemented by, for example, a central processing unit (CPU), a micro processing unit (MPU), or the like, executing a program according to an embodiment of the present disclosure stored in the storage unit 107 using the RAM as a work area. Note that the control unit 108 may be implemented by an integrated circuit such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA).

[0073] The control unit 108 includes an app execution unit 108 a , a display control unit 108 b , and a communication control unit 108 c , and implements or executes functions and actions of information processing described below.

[0074] The app execution unit 108a reads the app information 107a stored in the storage unit 107 and executes the camera app. For example, the app execution unit 108a selects the camera lens 17 of the camera 101 according to the operation content of the operation input from the operation unit 105 and related to the zoom function.

[0075] In addition, the app execution unit 108a also sets the zoom magnification of the camera lens 17 according to the operation content of the operation related to the zoom function. In addition, in order to set the zoom magnification, the app execution unit 108a controls the focal length variable mechanism 102 as needed, and sets the focal length of the third lens 17-T within the range of 85mm to 125mm.

[0076] Furthermore, the app execution unit 108a causes the camera 101 to perform photography at a set zoom magnification using the selected camera lens 17 according to a photography operation input from the operation unit 105. Furthermore, when executing the camera app, the app execution unit 108a causes the display control unit 108b to perform display control of visual information including various UIs.

[0077] The display control unit 108b performs display control of visual information on the display unit 106 when executing the camera app based on the measurement result of the inertial sensor unit 103 and the instruction of the app execution unit 108a. The communication control unit 108c performs communication control for an external device when executing the camera app.

[0078] <<2. Example of UI display related to zoom function>>

[0079] <2-1. First Display Example>

[0080] Next, we will refer to Figures 5 to 8 A first display example of a UI related to a zoom function according to an embodiment of the present disclosure is described. Figures 5 to 8 are diagrams (part 1) to (part 4) showing a first display example of a UI related to a zoom function.

[0081] like Figure 5 As shown, the display control unit 108 b displays various visual information related to the execution of the camera app on the first region R1 , the second region R2 , and the third region R3 of the touch screen TS.

[0082] In the first region R1, portal app information of the camera app, such as the currently set photography mode and menu, is displayed. In the second region R2, the selected camera lens 17 and the monitor screen of the camera direct recording image obtained at the set zoom magnification are displayed.

[0083] In the third region R3, a UI for various operations of the camera app is displayed. Figure 6 As shown, in the third region R3, as UI related to the zoom function, a first magnification setting button UB, a second magnification setting button WB, and a third magnification setting button TB are displayed.

[0084] The first magnification setting button UB corresponds to the selection button of the first lens 17-U. The second magnification setting button WB corresponds to the selection button of the second lens 17-W. The third magnification setting button TB corresponds to the selection button of the third lens 17-T.

[0085] The first magnification setting button UB is a button having a perfect circular shape, and indicates a magnification conversion value "x0.7" matching the focal length of the first lens 17-U. The second magnification setting button WB is also a button having a perfect circular shape, and indicates a magnification conversion value "x1.0" matching the focal length of the second lens 17-W. The third magnification setting button TB is a button having an elliptical shape, and indicates a range of magnification conversion values ​​"x3.5 to x5.2" (85 mm to 125 mm) matching the variable focal length of the third lens 17-T, that is, the optical zoom range mentioned above.

[0086] That is, in a case where the smartphone 10 includes a plurality of camera lenses 17 of different focal lengths, the display control unit 108 b presents a UI that clearly indicates the focal length matched to each camera lens 17 to the user.

[0087] Specifically, as shown in the third magnification setting button TB, in the case where the smartphone 10 includes an optical zoom lens with a variable focal length, the display control unit 108b presents a UI that clearly indicates the optical zoom interval (85 mm to 125 mm) that can be set by the zoom lens. Therefore, the user can easily grasp the matching focal length of each of the multiple camera lenses 17 included in the smartphone 10 and the settable optical zoom interval.

[0088] Here, if Figure 6 As shown in the left figure of FIG. , for example, it is assumed that the user performs a tap operation on the third magnification setting button TB. Then, as shown in FIG. Figure 6 As shown in the M1 interval in the right figure, the display control unit 108b presents to the user a UI that continuously indicates the range including the optical zoom interval of the third lens 17-T, and this range can be set to all the multiple camera lenses 17.

[0089] More specifically, if Figure 7 As shown in the M1 interval in FIG. 1 , the display control unit 108 b presents to the user a UI that continuously indicates the range from the minimum magnification to the maximum magnification, which range can be set to all of the plurality of camera lenses 17. In the case of an embodiment of the present disclosure, as Figure 7 As shown, the minimum magnification is "x0.7" matching the focal length of the first lens 17-U, and the maximum magnification is "x15.6" matching the maximum value of the digital zoom of the third lens 17-T. Hereinafter, a UI that continuously indicates the range from the minimum magnification to the maximum magnification that can be set to all of these multiple camera lenses 17 will be referred to as a "seamless zoom UI" as appropriate.

[0090] In addition, if Figure 7 As shown, when the user performs a sliding operation along the seamless zoom UI (see Figure 7 The display control unit 108b performs display control according to the sliding operation to enlarge or reduce the monitor screen in the second region R2 (see Figure 7 Arrow a2 in the figure).

[0091] Furthermore, when the user releases his finger from the seamless zoom UI, the app execution unit 108a sets the zoom magnification of the camera 101 associated with the position on the seamless zoom UI where the user released his finger. Figure 7 As shown, the optical zoom range "x3.5-x5.2" (85mm to 125mm) that can be set by the zoom lens is also grouped into an oval button and clearly indicated on the seamless zoom UI.

[0092] Note that although Figure 6 and Figure 7 An example is shown in which the display control unit 108b displays a seamless zoom UI as a UI related to the zoom function, and the seamless zoom UI may not be enabled depending on the type of camera app and the combination of the set photography mode, the on / off setting of the seamless zoom UI, etc.

[0093] Figure 8 An example of a case where the seamless zoom UI is not enabled in the first display example is shown. Figure 8As shown in the left figure of FIG. , for example, it is assumed that the user performs a tap operation on the third magnification setting button TB. Then, as shown in FIG. Figure 8 As shown in the M2 interval in the right figure, the display control unit 108b presents a UI to the user, which continuously indicates only the range of the optical zoom interval including the third lens 17-T, and the range can be set when the third lens 17-T is selected.

[0094] As described above, the off setting of the seamless zoom UI that does not enable the seamless zoom UI can be performed from the on / off setting UI of the seamless zoom UI, which is omitted in the illustration. In addition, examples of the types of the above-mentioned camera apps include "Photo Pro", "Video Pro" and "Movie Pro". "Photo Pro" is an app dedicated to photo photography, which pursues the fully mature operability and functionality of a digital camera. "Video Pro" is an app dedicated to video photography. "Movie Pro" is an app dedicated to video photography, which pursues to provide the operational feel and image creation of photography with a professional movie camera. In addition, the above-mentioned photography modes include a "basic" mode that enables photography to be easily performed, and various modes such as "Auto", "P", "S" and "M" that are well known as photography modes of digital cameras. Depending on these types of camera apps and the combination of setting the photography mode, the seamless zoom UI can be automatically enabled or disabled as appropriate.

[0095] <2-2. Second Display Example>

[0096] Next, we will refer to Figures 9 to 12 A second display example related to the zoom function according to an embodiment of the present disclosure is described. Figures 9 to 12 are diagrams (part 1) to (part 4) showing a second display example of a UI related to a zoom function.

[0097] In the second display example, the touch screen TS is rotated 90 degrees from the first display example. In this case, for example, Fig. 9 As shown, the display control unit 108b arranges the first region R1, the second region R2 and the third region R3 side by side in order from left to right.

[0098] In addition, the display control unit 108b displays the currently selected camera lens 17 in the third region R3, such as Fig. 9 Here, as shown in the M3 interval, it is assumed that "125 mm" (i.e., the third lens 17-T corresponding to this focal length) is being selected.

[0099] Furthermore, when the user performs a tap operation on the M3 section, the display control unit 108b superimposes and displays the lens selection screen LS on the third region R3 in response to the tap operation, as shown in FIG. Fig. 9 As shown in the figure below.

[0100] like Fig. 9 As shown, the lens selection screen LS is a screen that indicates the focal lengths "16 mm", "24 mm", and "85 mm to 125 mm" associated with the selectable camera lens 17 in an elliptical area in a selectable manner. For the third lens 17-T as a zoom lens, the optical zoom interval "85 mm to 125 mm" is clearly shown. For example, when the above-mentioned on / off setting of the seamless zoom UI is turned on, the lens selection screen LS is displayed.

[0101] In addition, if Fig.10 As shown in the M4 interval in FIG. 1 , it is assumed that the user selects the second lens 17-W associated with "24 mm", that is, the focal length on the lens selection screen LS. Fig.10 As shown in the figure below, the lens selection screen LS is erased and Fig.10 As shown in the M5 section in the figure below, slide bars corresponding to the zoom levers represented by T (telephoto) and W (wide angle) of the digital video camera appear from the lower side of the lens selection screen LS.

[0102] In the second display example, the slide bar in the M5 interval plays a role corresponding to the seamless zoom UI described above. More specifically, Fig.11 As shown in the above figure, when the user moves the slider SL of the slide bar to the "T" side beyond the center position of the bar (see arrow a3 in the above figure), the display control unit 108b zooms in on the monitor screen of the second region R2 according to the movement amount of the slider SL. In addition, the focal length at the above-mentioned M3 interval is displayed as the currently displayed zoom magnification, and the maximum value changes to "375mm".

[0103] On the other hand, Fig.11 As shown in the figure below, when the user moves the slider SL to the "W" side beyond the center position of the bar (see arrow a4 in the figure below), the display control unit 108b reduces the monitor screen of the second region R2 according to the movement amount of the slider SL. In addition, the focal length at the above-mentioned M3 interval is displayed at the currently displayed zoom magnification, and the minimum value changes to "16mm".

[0104] Furthermore, when the user releases the finger from the slider SL, the app execution unit 108 a sets the zoom magnification of the camera 101 associated with the position of the slider SL from which the user has released the finger.

[0105] Note that although reference has been made Fig.10 and Fig.11 Described, Fig.10 and 11 Quoting the user in Fig.1024mm” is selected on the lens selection screen LS shown in the M4 section in FIG. 1 , but if the seamless zoom UI is enabled, the smartphone 10 will not be displayed even when “16mm” or “85mm to 125mm” is selected. Fig.11 Proceed as shown.

[0106] Furthermore, similar to the first display example, the display control unit 108b may not enable the seamless zoom UI in the second display example.

[0107] Fig.12 An example of this situation is shown. First, assume that the user Fig. 9 Then, the display control unit 108b responds to the M3 interval shown in FIG. Fig.12 In the tap operation shown, the first magnification ratio setting button UB, the second magnification ratio setting button WB, and the third magnification ratio setting button TB are superimposed and displayed in the third region R3.

[0108] Fig.12 The first magnification setting button UB, the second magnification setting button WB, and the third magnification setting button TB shown in FIG. 1 are represented as focal lengths, and are similar to Figure 6 and Figure 8 1 , 2 , and 3 . In addition, when the user performs a tap operation on any of these buttons, each button is erased, and the slide bar indicated in the above-mentioned M5 section appears from the lower side.

[0109] However, when the seamless zoom UI is not enabled, the slide bar in the M5 interval does not function like the seamless zoom UI described above. That is, when each camera lens 17 is selected, the slide bar in the M5 interval serves as a UI that continuously indicates only the settable range of the digital zoom range including the selected camera lens 17. For example, when the first magnification setting button UB is selected, the magnification can be set within the range of 16 mm to 48 mm using the slide bar indicated in the M5 interval. Furthermore, for example, when the second magnification setting button WB is selected, the magnification can be set within the range of 24 mm to 85 mm using the slide bar indicated in the M5 interval. Furthermore, for example, when the third magnification setting button TB is selected, the magnification can be set within the range of 85 mm to 375 mm using the slide bar indicated in the M5 interval.

[0110] <2-3. Third Display Example>

[0111] Next, we will refer to Figures 13 to 15 A third display example related to the zoom function according to an embodiment of the present disclosure is described. Figures 13 to 15are diagrams (part 1) to (part 3) showing a third display example of a UI related to a zoom function.

[0112] like Fig.13 As shown, the third display example assumes that the display control unit 108b arranges the first region R1, the second region R2, and the third region R3 side by side, similar to the second display example.

[0113] In addition, the display control unit 108b displays the currently selected camera lens 17 in the first region R1, such as Fig.13 Here, as shown in the M6 ​​interval, it is assumed that "24 mm" (ie, the third lens 17-W corresponding to the focal length) is being selected.

[0114] Furthermore, when the user performs a tap operation on the M6 ​​section, the display control unit 108b displays a display similar to Fig.12 The first magnification setting button UB, the second magnification setting button WB and the third magnification setting button TB are shown. Fig.13 As shown in the figure below.

[0115] In addition, for example, when a user Fig.14 When a tap operation is performed on the third magnification setting button TB as shown in the above figure, the display control unit 108b Fig.14 As shown in the lower figure, a magnification setting ring CB is superimposed and displayed in the second region R2.

[0116] The magnification setting ring CB is an operating member, on which a scale indicates focal lengths associated with magnifications of optical zoom and digital zoom, and the scale is indicated on the outer circumference of an arc shape and is rotatably arranged around the center of the arc. On the magnification setting ring CB, the optical zoom zone OZS (85 mm to 125 mm) is clearly indicated separately from the digital zoom zone.

[0117] Therefore, the user can easily grasp the multiple camera lenses 17 ( Fig.14 The corresponding focal length of each camera lens in the third lens 17-T in the example and the settable optical zoom range OZS (85mm to 125mm).

[0118] Furthermore, when the user rotates the magnification setting ring CB to adjust the scale of a desired focal length to the index ID1, the zoom magnification associated with the corresponding scale is set.

[0119] More specifically, if Fig.15As shown in the above figure, for example, when the user rotates the magnification setting ring CB counterclockwise by a drag operation (see arrow a5 in the above figure), the display control unit 108b performs zooming in the monitor screen of the second region R2 according to the rotation amount of the magnification setting ring CB. In addition, the app execution unit 108a sets the zoom magnification associated with the focal length (here, "375" mm) adjusted by the user to the scale of the index ID1.

[0120] On the other hand, Fig.15 As shown in the figure below, when the user rotates the magnification setting ring CB clockwise by the drag operation (see arrow a6 in the figure below), the display control unit 108b reduces the monitor screen of the second region R2 according to the rotation amount of the magnification setting ring CB. In addition, the app execution unit 108a sets the zoom magnification associated with the focal length (here, "85" mm) adjusted by the user to the scale of the index ID1.

[0121] Note that although Fig.15 In the example of FIG. 1 , the enlargement setting ring CB is rotated by the user's drag operation, and the enlargement setting ring CB can be rotated by the user's pinch-in / pinch-out operation on the touch screen TS. The pinch-in / pinch-out operation is a touch operation in which the user widens or narrows the interval between two fingers while making two fingers contact with the touch screen TS.

[0122] In this case, the app execution unit 108a detects the amount of change in the interval between the two fingers as the pinch amount. In addition, the display control unit 108b rotates the magnification setting ring CB by the rotation amount matching the pinch amount detected by the app execution unit 108a. In addition, the display control unit 108b reduces / enlarges the monitor screen of the second region R2 according to the detected zoom amount. In addition, the app execution unit 108a sets the zoom magnification matching the focal length of the scale located at the index ID1 by rotating the magnification setting ring CB.

[0123] Note that the seamless zoom UI described so far is consistent with the reference Figure 6 and Figure 7 For the M1 interval described, refer to Fig.10 and Fig.11 In addition, a "telephoto optical zoom UI" may be defined for a seamless zoom UI. The telephoto optical zoom UI is a UI corresponding to Figure 6 , Figure 8 and Figures 12 to 15 The third magnification setting button TB shown, Fig.14 and Fig.15 Part of the OZS UI is shown.

[0124] <<3. Process>>

[0125] Next, we will refer to Fig.16 A processing procedure performed by the smartphone 10 according to an embodiment of the present disclosure is described. Fig.16 : is a flowchart showing a processing procedure executed by the smartphone 10. Note that in the case of a combination of a type of camera app that always displays a seamless zoom UI and a photographing mode, steps S105 and S107 are omitted.

[0126] like Fig.16 As shown, the smartphone 10 first activates the camera app (step S101). In addition, when a plurality of camera lenses 17 with different focal lengths including a zoom lens are provided, the smartphone 10 displays a UI related to the zoom function, which clearly indicates the optical zoom range (85 mm to 125 mm) of the zoom lens (step S102).

[0127] Furthermore, the smartphone 10 determines whether the selection operation of the camera lens 17 has been detected (step S103 ). When the selection operation of the camera lens 17 has not been detected (step S103 , No), step S103 is repeated.

[0128] When the selection operation of the camera lens 17 is detected (step S103 , Yes), the smartphone 10 selects the camera lens 17 matching the operation (step S104 ).

[0129] Furthermore, the smartphone 10 determines whether the on / off setting of the seamless zoom UI is on (step S105 ). Here, in the case where the setting is on (step S105 , Yes), the smartphone 10 displays the seamless zoom UI (step S106 ).

[0130] On the other hand, in the case where the setting is off (step S105 , No), the smartphone 10 displays a non-seamless zoom UI which is a UI related to the zoom function other than the seamless zoom UI (step S107 ).

[0131] Furthermore, the smartphone 10 sets the magnification ratio through the zoom UI related to the displayed zoom function (step S108 ), and ends the processing.

[0132] <<4. Modification>>

[0133] Meanwhile, the above-described embodiments of the present disclosure may include several modifications.

[0134] Although the above-mentioned embodiment of the present disclosure has described an example in which the smartphone 10 includes the camera 101 , and the camera app is a photography app using the camera 101 , the smartphone 10 and the camera 101 may be separate bodies.

[0135] That is, in this case, the camera as an external device separate from the smartphone 10 includes a plurality of camera lenses of different focal lengths including an optical zoom lens. In addition, the smartphone 10 functions as an information processing device, i.e., a so-called remote controller, which remotely controls the camera via the camera app through wired communication or wireless communication via the communication unit 104.

[0136] Furthermore, although the embodiment of the present disclosure has described an example in which the camera 101 is an optical system device and the camera app is an operation app for the optical system device, the optical system device is not limited to the camera 101. For example, the optical system device may be a telescope or the like.

[0137] That is, in this case, the telescope includes a plurality of lenses of different focal lengths, the plurality of lenses of different focal lengths including a zoom lens, and the operation app of the telescope displays a UI that clearly indicates the optical zoom interval of the zoom lens used for the zoom function of the lens of the telescope. In addition, the app displays a seamless zoom UI that continuously indicates the range from the minimum magnification to the maximum magnification that can be set for all the plurality of lenses.

[0138] In addition, all or part of the processing described as automatically performed in each of the processes described in the above embodiments of the present disclosure may be manually performed, or all or part of the processing described as manually performed may be automatically performed by a known method. In addition, unless otherwise specified, the processing procedures, specific names, and information including various data items and parameters shown in the above description and the accompanying drawings may be arbitrarily changed. For example, the various information shown in each of the accompanying drawings is not limited to the information shown.

[0139] In addition, each component of each illustrated device is conceptual in function and does not necessarily need to be physically configured as illustrated. That is, the specific mode of distribution and integration of each device is not limited to the mode illustrated, and all or part of the components may be functionally or physically distributed / integrated and configured in any unit according to various loads, usage conditions, etc.

[0140] Furthermore, the above-described embodiments of the present disclosure may be appropriately combined within the range in which the processing contents do not contradict each other. Furthermore, the order of each step shown in the sequence diagram or flowchart of the present embodiment may be appropriately changed.

[0141] <<5. Hardware Configuration>>

[0142] The smartphone 10 according to the above-described embodiment of the present disclosure is implemented, for example, by using Fig.17 The configuration of computer 1000 is shown. Fig.17 10 is a hardware configuration diagram showing an example of a computer 1000 that realizes the functions of the smartphone 10. The computer 1000 includes a CPU 1100, a RAM 1200, a ROM 1300, a hard disk drive (HDD) 1400, a communication interface 1500, and an input / output interface 1600. Each unit of the computer 1000 is connected by a bus 1050.

[0143] The CPU 1100 operates based on the program stored in the ROM 1300 or the HDD 1400 and controls each unit. For example, the CPU 1100 expands the program stored in the ROM 1300 or the HDD 1400 in the RAM 1200 and executes processing corresponding to various programs.

[0144] The ROM 1300 stores a boot program such as a basic input output system (BIOS) executed by the CPU 1100 when the computer 1000 is activated, a program depending on the hardware of the computer 1000 , and the like.

[0145] The HDD 1400 is a computer-readable recording medium that can non-transitorily record a program executed by the CPU 1100 , data used by the program, etc. More specifically, the HDD 1400 is a recording medium that records a program according to the present disclosure, which is an example of the program data 1450 .

[0146] The communication interface 1500 is an interface for connecting the computer 1000 to an external network 1550 (eg, the Internet). For example, the CPU 1100 receives data from another device and transmits data generated by the CPU 1100 to another device via the communication interface 1500.

[0147] The input / output interface 1600 is an interface for connecting the input / output device 1650 and the computer 1000. For example, the CPU 1100 receives data from input devices such as a keyboard and a mouse via the input / output interface 1600. In addition, the CPU 1100 sends data to an output device such as a display, a speaker, or a printer via the input / output interface 1600. In addition, the input / output interface 1600 can be used as a medium interface for reading a program recorded in a predetermined recording medium (medium), etc. For example, the medium is an optical recording medium such as a digital versatile disk (DVD) and a phase change rewritable disk (PD), a magneto-optical recording medium such as a magneto-optical disk (MO), a magnetic tape medium, a magnetic recording medium, a semiconductor memory, etc.

[0148] For example, in the case where the computer 1000 is used as the smartphone 10 according to the present embodiment, the CPU 1100 of the computer 1000 implements the functions of the control unit 108 and the like by executing the program loaded on the RAM 1200. In addition, the HDD 1400 stores the program and data according to the present disclosure in the storage unit 107. Note that although the CPU 1100 reads the program data 1450 from the HDD 1400 to execute, in another example, these programs may be acquired from another device via the external network 1550.
