Description

[Technical field]

[0001] The present invention relates to an information processing device, a control method for an information processing device, and a program. [Background technology]

[0002] In recent years, imaging devices such as digital cameras are equipped with wireless communication functions and wired connection functions. If the imaging device is connected to an information terminal (such as a smartphone or tablet) via wireless communication or wired communication, the information terminal can remotely control the imaging device by using an application in the information terminal.

[0003] Touch operations are the mainstream for operating information terminals. A touch operation section (buttons, slide bars, wheels, etc.) is displayed on the screen, and the user is allowed to operate the touch operation section. When controlling an imaging device remotely, the imaging device can also be controlled (for example, the settings of the imaging device can be changed) by operating the touch operation section displayed on the screen of the information terminal. On the other hand, touch operations on a screen, unlike operations on physical buttons, provide little feedback to the operator. For this reason, the operator may not obtain the operation results he or she expected.

[0004] For this reason, a method of providing feedback for touch operations has been proposed. Patent Document 1 describes a method of providing feedback to an operator by using a change in vibration when the operator has slid to a target point in a touch slide operation (operation of sliding while touching). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2018-128741 A Summary of the Invention [Problem to be solved by the invention]

[0006] When changing settings by touch-slide operation, providing feedback by vibration at the timing of changing the settings using the technology of Patent Document 1 is useful for improving operability. However, for example, when operating the zoom of an imaging device, the settings change continuously (changes occur constantly during operation), and providing feedback by vibration causes vibrations to occur constantly during operation. This results in unnecessary vibrations, reducing the operability of the touch-slide operation.

[0007] Therefore, an object of the present invention is to improve operability when changing settings by performing a sliding operation while touching. [Means for solving the problem]

[0008] One aspect of the present invention is a method for producing a composition comprising the steps of: An information processing device having a touch area that accepts a touch by a user, A detection means for detecting a touch slide operation, which is an operation of sliding while touching the touch area; A change means for changing a setting of a specific device in response to the touch slide operation; a notification means for notifying the user of a change in the setting of the specific device; 1) when a setting of a first setting item is changed in response to the touch slide operation, the change in the setting of the first setting item is notified by the notification means, and 2) when a setting of a second setting item is changed in response to the touch slide operation, the change in the setting of the second setting item is notified by the notification means. A control means for controlling the notification means not to notify the change; The information processing device is characterized by having:

[0012] Hereinafter, the embodiment for carrying out the present invention will be described in detail with reference to the attached drawings. Note that the embodiment described below is one example of a method for implementing the present invention, and may be appropriately modified or changed depending on the configuration of the device to which the present invention is applied and various conditions. In addition, each embodiment can be appropriately combined.

[0013] <Embodiment 1> 1A shows an information processing system 1 according to a first embodiment. The information processing system 1 includes an imaging device 100 and an information terminal 200. The imaging device 100 is, for example, an electronic device (information processing device) such as a digital camera. The information terminal 200 is, for example, an electronic device (information processing device) such as a smartphone, a tablet, a digital camera (imaging device), or a computer. The imaging device 100 is connected to the information terminal 200 through communication 300. The communication 300 may be wireless communication or wired communication.

[0014] 2 is a block diagram showing an example of the configuration of the imaging device 100. The imaging device 100 includes a control unit 101, an imaging unit 102, a non-volatile memory 103, a working memory 104, an operation unit 105, a display unit 106, a recording medium 110, and a connection unit 111.

[0015] The control unit 101 controls each unit of the imaging device 100 in accordance with an input signal or a program. Instead of the control unit 101 controlling the entire imaging device 100, the entire imaging device 100 may be controlled by having a plurality of hardware devices share the processing.

[0016] The imaging unit 102 acquires an image (hereinafter referred to as a "camera image") of a subject (real space). The imaging unit 102 includes a lens. The imaging unit 102 converts the subject light imaged by the lens into an electrical signal. The imaging unit 102 then performs noise reduction processing on the electrical signal to obtain digital data, which it outputs as a camera image. The camera image is stored in a buffer memory, and then a predetermined calculation is performed by the control unit 101, and the image is recorded on the recording medium 110.

[0017] The non-volatile memory 103 is an electrically erasable and recordable non-volatile memory, and stores programs executed by the control unit 101 and the like.

[0018] The working memory 104 is used as a buffer memory for temporarily storing camera images captured by the imaging unit 102. The working memory 104 is also used as an image display memory for the display unit 106, a working area for the control unit 101, and the like.

[0019] The operation unit 105 receives instructions from a user for the imaging device 100. The operation unit 105 includes, for example, a power button that allows the user to instruct the imaging device 100 to be turned on / off. The operation unit 105 includes operation members such as a release switch for instructing shooting and a playback button for instructing image playback. The operation unit 105 also includes a touch panel formed on the display unit 106.

[0020] The release switch has a switch SW1 and a switch SW2. When the release switch is pressed halfway, switch SW1 turns ON. This allows operation unit 105 to receive instructions for processing to prepare for shooting (AF (autofocus) processing, AE (auto exposure) processing, AWB (auto white balance) processing, EF (pre-flash) processing, etc.). When the release switch is pressed all the way, switch SW2 turns ON. This allows operation unit 105 to receive instructions for shooting.

[0021] The display unit 106 displays a viewfinder image during shooting, a camera image, and characters for interactive operations. The display unit 106 does not necessarily have to be built into the imaging device 100. The imaging device 100 only needs to be able to connect to an internal or external display unit 106 and to be able to control the display of the display unit 106.

[0022] The recording medium 110 records camera images. The recording medium 110 may be detachable from the imaging device 100, or may be built into the imaging device 100. In other words, it is sufficient that the imaging device 100 is at least able to access the recording medium 110.

[0023] The connection unit 111 is an interface for connecting to an external device (such as the information terminal 200). The imaging device 100 can exchange data with the external device via the connection unit 111. The connection unit 111 includes an interface for wireless communication with the external device. The control unit 101 controls the connection unit 111 to realize wireless communication with the external device.

[0024] 3 is a block diagram showing an example of the configuration of an information terminal 200. The information terminal 200 includes a control unit 201, an imaging unit 202, a non-volatile memory 203, a working memory 204, an operation unit 205, a display unit 206, a recording medium 210, a connection unit 211, a public network connection unit 212, a microphone 213, a speaker 214, and a vibration element 215.

[0025] The control unit 201 controls each unit of the information terminal 200 according to an input signal and a program. Instead of the control unit 201 controlling the entire information terminal 200, the entire information terminal 200 may be controlled by having a plurality of hardware devices share the processing.

[0026] The imaging unit 202 captures an image (hereinafter referred to as a "terminal image") by capturing an image of a subject (real space). The imaging unit 202 includes a lens. The imaging unit 202 converts the subject light imaged by the lens into an electrical signal. The imaging unit 202 captures digital data obtained by performing noise reduction processing on the electrical signal as the terminal image. The terminal image is stored in a buffer memory, and then a predetermined calculation is performed by the control unit 201 and the terminal image is recorded on the recording medium 210.

[0027] The non-volatile memory 203 is an electrically erasable and recordable non-volatile memory, and stores an OS (operating system) which is basic software executed by the control unit 201, various programs, and the like.

[0028] In the first embodiment, the non-volatile memory 203 holds a program for communicating with the imaging device 100. This program is installed in the information terminal 200 as a camera communication application. The processing of the information terminal 200 in the first embodiment is realized by a program provided by the camera communication application. The camera communication application has a program for using basic functions (e.g., wireless communication function and vibration function) of the OS installed in the information terminal 200. The camera communication application also has a "remote shooting function for the information terminal 200 to remotely control the imaging device 100 to shoot while displaying a camera image, which is a live view image obtained from the imaging device 100, on the information terminal 200". Furthermore, the camera communication application has a setting change function for remotely changing the settings of the imaging device 100. The OS of the information terminal 200 may have a program for realizing the processing in the first embodiment.

[0029] The working memory 204 is used as a buffer memory for temporarily storing terminal images, and is also used as an image display memory for the display unit 206, a working area for the control unit 201, and the like.

[0030] The operation unit 205 is used to receive instructions from a user for the information terminal 200. The operation unit 205 includes, for example, a power button for instructing ON / OFF of the power of the information terminal 200. The operation unit 205 also includes an operation member such as a touch panel formed on the display unit 206.

[0031] The display unit 206 displays a terminal image, a camera image, characters for interactive operations, and the like. Note that the display unit 206 does not necessarily need to be built into the information terminal 200. The information terminal 200 only needs to be able to connect to the display unit 206 and to be able to control the display of the display unit 206.

[0032] The recording medium 210 records the terminal image output from the imaging unit 202 and the camera image received from the imaging device 100. The recording medium 210 may be detachable from the information terminal 200, or may be built into the information terminal 200. In other words, it is sufficient that the information terminal 200 is at least capable of accessing the recording medium 210.

[0033] The connection unit 211 is an interface for connecting to an external device (such as the imaging device 100). The information terminal 200 can exchange data with the external device via the connection unit 211. The connection unit 211 includes an interface for wireless communication with the external device. The control unit 201 controls the connection unit 211 to realize wireless communication with the external device.

[0034] The public network connection unit 212 is an interface used when performing communication using public wireless. The information terminal 200 can perform telephone calls and data communications via the public network connection unit 212. When performing a telephone call, the control unit 201 obtains surrounding sounds through the microphone 213 and emits (outputs) the sounds through the speaker 214.

[0035] The vibration element 215 vibrates based on a drive voltage output from the control unit 201. This causes the information terminal 200 itself to vibrate. In the first embodiment, the vibration element 215 is a notification unit that notifies a change in a setting value of a specific setting item by vibrating the information terminal 200.

[0036] An example of changing settings (settings related to shooting) of the imaging device 100 using a setting change UI (user interface) will be described below with reference to Fig. 4A. Fig. 4A shows an example of a setting change UI 400 in the first embodiment.

[0037] The setting change UI 400 is displayed on the display unit 206 of the information terminal 200 by an application installed on the information terminal 200 or a program included in the OS of the information terminal 200 .

[0038] A setting item 401 is a setting item of a setting value (setting) that can be changed in the setting change UI 400. In the example of Fig. 4A, the setting item 401 indicates a setting item of gain (a setting value for adjusting brightness).

[0039] The current setting 402 indicates the current setting value (setting) of the setting item 401. Depending on the content, the setting item 401 may not be expressed by a numerical value. In this case, the current setting 402 may be displayed by a bar, for example, instead of a numerical value (see FIG. 6). In the first embodiment, the current setting 402 is acquired from the imaging device 100 via the connection unit 111 and the connection unit 211.

[0040] The touch operation unit 403 is an area (touch area) operated by the user to change the current setting 402. The touch operation unit 403 is, for example, a wheel- or slide-bar-shaped operation unit. When the user operates the touch operation unit 403, the operation unit 205 (touch panel) detects (senses) the operation. Then, when the control unit 201 determines that the detected operation is an operation for changing the setting, it changes the current setting 402. Furthermore, the control unit 201 notifies the imaging device 100 of the current setting 402 (a setting value corresponding to the operation for changing the setting) via the connection unit 211 and the connection unit 111. The control unit 101 of the imaging device 100 applies the current setting 402 to the imaging device 100 and saves it in the non-volatile memory 103 or the working memory 104. This realizes a change in the setting value corresponding to the operation for changing the setting.

[0041] At this time, the control unit 201 determines whether or not to provide feedback (notification) of the setting change to the user based on the contents of the setting item 401. When providing feedback of the setting change to the user, the control unit 201 vibrates the vibration element 215.

[0042] The image 404 is a camera image (live view image) acquired by the imaging unit 102. The display form or image quality of the image 404 is controlled according to the setting value depending on the content of the setting item 401. Also, the image 404 does not have to be displayed depending on the content of the setting item 401.

[0043] FIG. 5 is a diagram showing a vibration feedback control method (hereinafter, “vibration feedback control method”) according to the first embodiment. FIG. 13 is a diagram showing an example of a setting change operation involving a setting change request (referred to as "setting change request").

[0044] Display surfaces 501A to 501E show the state of the display surface (setting change UI 400) of display unit 206 in chronological order when the touch operation unit is operated (when a touch slide operation is being performed). Setting values ​​502A to 502E show setting values ​​corresponding to the touch operation.

[0045] Presence or absence of vibration feedback 503A to 503E indicate the presence or absence of vibration feedback accompanying a change in the set value.

[0046] On display surface 501B, the amount of operation on the touch operation unit has not reached the amount of operation (=threshold) that would result in a change in the setting. Therefore, setting value 502B has not been changed from setting value 502A. And, as shown by presence / absence of vibration feedback 503B, vibration feedback is not performed.

[0047] On display surface 501C, the amount of operation on the touch operation unit has reached the amount of operation that results in a change in the setting. Therefore, setting value 502C has been changed from setting value 502B. Then, as indicated by presence / absence of vibration feedback 503C, vibration feedback is performed.

[0048] In Fig. 5, the setting item for which the setting value is changed is the gain setting item of the imaging device 100 (camera). In the case of a setting item such as a gain setting, exposure compensation, frame rate, or shutter speed, where the change in the setting value is discontinuous (the setting value changes step by step with a certain amount of slide operation), vibration feedback is generated. This makes it easy for the user to understand the timing of the change in the setting value, and makes it easy for the user to intuitively change the setting.

[0049] FIG. 6 is a diagram illustrating an example of a setting change operation without vibration feedback according to the first embodiment.

[0050] Display surfaces 601A to 601E show the state of the display surface (setting change UI 400) of display unit 206 in chronological order when the touch operation unit is operated (when a touch slide operation is being performed). Setting values ​​602A to 602E show setting values ​​corresponding to touch operations.

[0051] Presence or absence of vibration feedback 603A to 603E indicate the presence or absence of vibration feedback accompanying a change in the set value.

[0052] On display surface 601B, a setting value 602B has been changed from setting value 602A by an operation on the touch operation unit. However, as indicated by presence / absence of vibration feedback 603B, vibration feedback is not performed.

[0053] On display surface 601C, a setting value 602C is changed from setting value 602B by an operation on the touch operation unit. However, as shown in presence / absence of vibration feedback 603C, vibration feedback is not performed. In other words, when the setting value is changed as shown in FIG. 6, vibration feedback is not performed under any circumstances.

[0054] In Fig. 6, the setting item whose setting value is changed is the zoom setting item of the camera. In the case of a setting item whose setting value changes continuously (the setting value changes during operation regardless of the amount of slide operation) such as the zoom setting or focus setting item, vibration feedback will cause constant vibration during operation. For this reason, it is necessary to prevent unnecessary Vibrations (notifications) may occur, which may interfere with operation. In addition, since vibration feedback is not provided, the operation feels different from when changing the setting value of a setting item that provides vibration feedback, and the user can easily intuitively feel that the setting value is changing continuously.

[0055] Even if the change in the setting value in response to the operation is continuous, vibration feedback may be performed only at specific points, not for each change in the setting value. For example, in the focus setting of a camera, the setting value (focal length) changes continuously. Here, vibration feedback is performed only when the setting value reaches a value corresponding to the in-focus point by the operation on the touch operation unit, making it easier for the user to adjust the focus. Note that "continuous change in the setting value" also includes discontinuous change in very fine units that humans perceive as continuous, even if the change is not strictly continuous.

[0056] A process for switching the implementation of vibration feedback depending on the contents of a setting item will be described with reference to the flowchart in Fig. 7. This flowchart shows the process contents performed by the information terminal 200 in accordance with a program. In the following, the setting item of the imaging device 100 for which the user changes the setting value (setting) will be referred to as a "target item".

[0057] In step S701, the control unit 701 determines whether or not "a slide operation (touch slide operation) for changing a setting value while the user is touching the operation unit 205" (hereinafter referred to as "setting change operation") has been performed on the touch operation unit. If it is determined that a setting change operation has been performed, the process proceeds to step S702. If it is determined that a setting change operation has not been performed, the process of step S701 is repeated.

[0058] In step S702, the control unit 201 determines whether the target item is an item that generates vibration feedback (whether the change in the set value according to the operation is discontinuous). If it is determined that the target item is an item that generates vibration feedback, the process proceeds to step S703. If it is determined that the target item is not an item that generates vibration feedback, the process proceeds to step S705.

[0059] For example, when the control unit 201 determines that the target item is an item that generates vibration feedback, the control unit 201 may display a plurality of vibration points 410 as shown in FIG. 4B on the touch operation unit. On the other hand, when the control unit 201 determines that the target item is not an item that generates vibration feedback, the control unit 201 does not display a plurality of vibration points 410 as shown in FIG. 4B on the touch operation unit. The vibration point 410 is a display item that indicates that vibration feedback is performed (=the setting value of the target item is changed) when (each time) the touch position of the user reaches the vibration point 410. The position at which the vibration point 410 is displayed is calculated based on the start position of the user's touch and a threshold value in step S703 described later. Specifically, the distance between two adjacent vibration points 410 is an amount corresponding to the threshold value, and the distance between the start position of the touch and the vibration point 410 adjacent thereto is an amount corresponding to the threshold value. This allows the user to visually grasp how much of a slide operation is required to change the setting value.

[0060] In step S703, the control unit 701 judges whether the sliding amount of the setting change operation exceeds the "amount that causes the setting value of the target item to be changed" (=threshold value). If it is judged that the sliding amount exceeds the threshold value, the process proceeds to step S704. If it is judged that the sliding amount is equal to or less than the threshold value, the process proceeds to step S706.

[0061] In step S704, the control unit 201 vibrates the vibration element 215 to perform vibration feedback. The vibration notifies the user that the setting value of the target item will be changed.

[0062] In step S705, the control unit 201 changes the setting value of the target item in response to the setting change operation. Specifically, the control unit 201 notifies the imaging device 100 of the setting value (the setting value of the target item) in response to the setting change operation. Then, the control unit 201 controls the control unit 101 of the imaging device 100 in response to the notification, applies the setting value of the target item to the imaging device 100, and saves it in the non-volatile memory 203 or the working memory 204.

[0063] In step S706, the control unit 201 determines whether or not the setting change operation on the operation unit 205 has ended. For example, the control unit 201 determines that the setting change operation has ended when the state in which the hand is touching the operation unit 205 is resolved. If it is determined that the setting change operation has ended, the process of this flowchart ends. If it is determined that the setting change operation has not ended, the process proceeds to step S702.

[0064] According to the first embodiment, when a setting value that changes discontinuously in response to an operation is changed, vibration feedback is provided to the user. On the other hand, when a setting value that changes continuously in response to an operation is changed, vibration feedback is not provided to the user. Therefore, the user can clearly understand whether or not a setting value has been changed for a setting item whose setting value does not change unless a certain amount of operation is performed. The user can clearly understand that the setting item whose setting value changes continuously in response to an operation is a setting item whose setting value changes continuously in response to an operation because vibration feedback is not provided to the user. Therefore, the operability of the user is improved when changing a setting value by a touch slide operation.

[0065] It has been described that touch operation unit 403 is displayed on display unit 106. However, touch operation unit 403 may be a physical operation member arranged independently of display unit 106 as long as it is capable of receiving a touch slide operation. For example, touch operation unit 403 may be a touch pad or a slide bar. Furthermore, these notification methods may be combined.

[0066] Furthermore, the change in the setting value is notified by vibrating the information terminal 200, but may be notified by emitting a sound from the speaker 214 of the information terminal 200. Alternatively, the change in the setting value may be notified by a change in the display form, such as by blinking the display unit 106.

[0067] Furthermore, the control unit 201 may not vibrate the information terminal 200 in any case if the imaging device 100 or the information terminal 200 is in a specific state. Specifically, even if the target item is determined to be an item that generates vibration feedback in step S702, if the imaging device 100 or the information terminal 200 is in a specific state, the control unit 201 may not vibrate the information terminal 200 in step S704. Here, the specific state is, for example, a state in which the user sets the information terminal 200 not to notify the user of changes in the setting value. In addition, the specific state may be, for example, an imaging state in which the imaging device 100 is imaging (taking a picture) of a subject, or a video playback state in which the imaging device 100 is playing a video.

[0068] <Variation 1> 1B, the system 1 according to the first embodiment may be configured by a single information terminal 200. That is, the information terminal 200 may include each component of the imaging device 100. In this case, the information terminal 200 changes the setting values ​​of the setting items of the information terminal 200 itself in response to a slide touch operation.

[0069] The processing of information terminal 200 may be realized by an installed application, or the OS of information terminal 200 may have a program. When the processing is realized by an installed application, the application has a program for utilizing the basic functions of the OS.

[0070] Although the present invention has been described in detail based on the preferred embodiments, the present invention is not limited to these specific embodiments, and various forms within the scope of the gist of the present invention are also included in the present invention. Parts of the above-described embodiments may be combined as appropriate.

[0071] Also, in the above, "If A is equal to or greater than B, proceed to step S1, and if A is smaller (lower) than B, proceed to step S2" may be read as "If A is greater (higher) than B, proceed to step S1, and if A is equal to or less than B, proceed to step S2." Conversely, "If A is greater (higher) than B, proceed to step S1, and if A is equal to or less than B, proceed to step S2" may be read as "If A is greater (higher) than B, proceed to step S1, and if A is smaller (lower) than B, proceed to step S2." Therefore, unless a contradiction occurs, "equal to or greater than A" may be read as "equal to or greater than A (high; long; many)," and "equal to or less than A" may be read as "equal to or less than A (low; short; few)." And, "equal to or greater than A" may be read as "equal to or greater than A," and "equal to or less than A" may be read as "equal to or less than A."

[0072] Each functional unit in each of the above embodiments (variations) may or may not be individual hardware. The functions of two or more functional units may be realized by common hardware. Each of a plurality of functions of one functional unit may be realized by individual hardware. Two or more functions of one functional unit may be realized by common hardware. Furthermore, each functional unit may or may not be realized by hardware such as an ASIC, FPGA, or DSP. For example, the device may have a processor and a memory (storage medium) in which a control program is stored. Then, the functions of at least some of the functional units of the device may be realized by the processor reading and executing the control program from the memory.
