Description

  The present invention relates to a portable information terminal, and more particularly to an improvement of a portable information terminal capable of restricting browsing by a third party of information related to a highly confidential contact information.

  In order to protect the user's privacy, a portable information terminal is known that can select a privacy mode for concealing information about a contact address designated in advance by a user as a member to be concealed from a third party. For example, browsing of sent / received mail with a member to be concealed is restricted. Furthermore, there is also known a portable information terminal that does not notify the reception of an email when receiving an email from a confidential member.

  In the case where notification of mail reception is not performed, there is a problem that the user is troublesome for the user because it is necessary to perform confirmation operation of mail reception from the member to be concealed. For this reason, it is known to notify the reception of mail from a member to be concealed by a method that can be discriminated only by the user. For example, Patent Document 1 describes that a user is notified of an incoming call from a member to be concealed by changing the wallpaper of a standby screen or the color of a battery icon. Patent Document 2 describes that when an e-mail is received from a member to be concealed, the user is notified of the reception of the e-mail by displaying dummy information predetermined by the user. It also describes that the user is notified of the reception of the mail by changing the brightness of the backlight and the lighting time.

Japanese Patent No. 4116627 JP 2012-10234 A

  In the method of Patent Document 1, since the changed wallpaper and battery icon are always displayed, there is a problem that it is easy for a third party to detect that there is an incoming call from a member to be concealed. Further, in the method of displaying dummy information described in Patent Document 2, when a large number of e-mails are received from members to be concealed, dummy information having the same contents is displayed many times, so that it is detected by a third party. There was a problem that it was easy to be done. Further, the brightness and lighting time of the backlight are often automatically changed according to the usage environment and usage. For this reason, even if the user is notified of email reception from the concealment target member by changing the backlight brightness or lighting time, it is determined that the change in backlight brightness or lighting time is due to email reception. There was a problem that it was difficult to do.

  The present invention has been made in view of the above circumstances, and it is possible for a user to determine whether there is an incoming call from a concealment target member while preventing a third party from detecting that the incoming call has been received from the concealment target member. It is an object to provide a portable information terminal that can be easily identified.

  The portable information terminal according to the present invention supplies a power supply for turning on the backlight based on a first reception notification means for performing a reception notification when receiving a communication signal and a user operation while the backlight of the display is turned off. And a second reception notification means for displaying a restart screen on the display after the backlight is turned on and displaying either the first object or the second object as a part of the moving image on the restart screen; Concealment target member storage means for holding the sender information of the target member, and transmission source comparison means for comparing the transmission source of the communication signal and the sender information of the concealment target member when the communication signal is received. Provided that when the transmission source of the communication signal does not match the sender information, the first reception notification unit performs reception notification, and the second reception notification unit performs the restart image. When the first object is displayed for a certain period of time immediately after the display, and the transmission source of the communication signal matches the sender information, the first reception notification means does not perform the reception notification, and the second reception notification means. Is configured to display the second object for a certain period of time immediately after the resumption screen is displayed.

  In this portable information terminal, when a communication signal is received from a transmission source other than the member to be concealed, the first reception notification means performs reception notification, whereas when a communication signal is received from the member to be concealed, One reception notification means does not perform reception notification. For this reason, it can suppress that the third party detects that there was an incoming call from the member to be concealed. Different objects are displayed on the resumption screen when the incoming call is from the confidential member and when the incoming call is from a transmission source other than the confidential member. For this reason, the user can easily identify whether or not there is an incoming call from the member to be concealed. Furthermore, since the object is displayed for a certain period of time immediately after the resumption screen displayed after the backlight is turned on, it is difficult for a third party to detect that there is an incoming call from the member to be concealed. Note that the communication signal includes an incoming call signal and an incoming e-mail notification.

  Advantageous Effects of Invention According to the present invention, a portable information terminal that allows a user to easily identify whether there is an incoming call from a confidential target member while preventing a third party from detecting that the incoming call has been received from a confidential target member Can be provided.

  FIG. 1 is a perspective view showing a configuration example of a portable information terminal 1 according to an embodiment of the present invention. The portable information terminal 1 is composed of, for example, a mobile phone that can communicate with a base station via cellular communication, and can transmit a call signal to the base station or receive an incoming signal from the base station. In addition, electronic mail can be transmitted to and received from the base station. The portable information terminal 1 includes a thin casing 10, an LED indicator 11, a receiving speaker 12, a touch panel 13, a transmitting microphone 14, and operation keys 15a to 15c.

  The thin casing 10 has a vertically long rectangular parallelepiped shape with the vertical direction as the longitudinal direction, and the LED indicator 11, the speaker 12, the touch panel 13, the microphone 14, and the operation keys 15 a to 15 c are arranged on the front surface of the thin casing 10. Yes. The LED indicator 11 and the speaker 12 are disposed at the upper end of the thin casing 10, and the microphone 14 and the operation keys 15 a to 15 c are disposed at the lower end of the thin casing 10.

  The touch panel 13 includes a display that displays various information including characters and images, and detects a touch operation on the display surface of the display. For example, the display includes a liquid crystal display panel having a rectangular display screen that is long in the vertical direction, and a backlight for illuminating the display screen.

  The LED indicator 11 is a display device for notifying an incoming call or mail reception by turning on an LED (light emitting diode). For example, the notification content can be identified by changing the lighting color or lighting interval of the LED. The speaker 12 is a sound output device for outputting a received sound. The microphone 14 is a voice input device for inputting a transmission sound.

  Each of the operation keys 15a to 15c includes a push-down contact type switch, and various functions are assigned thereto. For example, the operation key 15b is a standby display key for displaying a standby screen. The operation key 15c is a power key for switching the lighting state and extinguishing state of the backlight, or switching the main power source on and off.

  In the portable information terminal 1, a privacy mode and a normal mode can be selected. The privacy mode is an operation mode for concealing information related to user privacy from a third party. In the privacy mode, information related to a contact specified in advance by the user as a member to be concealed, such as outgoing / incoming histories and sent / received mails, is not displayed, and no incoming notification is given when there is an incoming call from the member to be concealed.

  The normal mode is an operation mode in which information related to user privacy is not concealed. In the normal mode, the transmission / reception history of the member to be concealed and the transmitted / received mail are displayed, and an incoming notification is also made when there is an incoming call from the member to be concealed. That is, the normal mode here is an operation mode in which the privacy information is temporarily released. In order to cancel the privacy mode, user authentication using a password or the like is necessary. If the user authentication is successful, the privacy mode is canceled and the normal mode is entered.

<Portable information terminal 1>
FIG. 2 is a block diagram showing an example of a functional configuration in the portable information terminal 1 of FIG. The portable information terminal 1 includes a main control unit 100, a cellular communication unit 110, an operation unit 120, a power supply unit 130, a display control unit 140, an audio processing unit 150, and an LED indicator 11.

  The main control unit 100 performs main control such as call control. The cellular communication unit 110 is a wireless communication unit that receives a communication signal from a cellular base station. The communication signal includes a call signal at the time of incoming call, a reception notification signal for notifying from the cellular base station that an electronic mail has been received, and the like. The operation unit 120 generates an operation signal corresponding to the operation of the touch panel 13 or the operation keys 15a to 15c.

  The power supply unit 130 is a power supply unit including a built-in battery (not shown) such as a secondary battery, and supplies a direct current to each device such as the touch panel 13. The power supply unit 130 turns off the backlight by cutting off the power supply to the touch panel 13 when the user presses the operation key 15c while the backlight of the touch panel 13 is turned on. In addition, in order to reduce power consumption, even when a state in which no user operation is performed passes for a predetermined time, the power supply to the touch panel 13 is cut off and the backlight is automatically turned off. On the other hand, if the operation key 15b is pressed while the backlight is turned off, the power supply unit 130 resumes power supply to the touch panel 13 and turns on the backlight.

  The display control unit 140 performs display control of the touch panel 13. The audio processing unit 150 amplifies the audio signal collected by the microphone 14, converts it into digital data and outputs it to the main control unit 100, while converting the audio data output from the main control unit 100 into an analog signal. Drive signal is generated and output to the speaker 12.

<Main control unit 100>
FIG. 3 is a block diagram illustrating a configuration example of the main control unit 100 of FIG. The main control unit 100 includes a mode switching unit 20, a transmission source comparison unit 21, a sender information storage unit 22, a reception notification unit 23, a secret incoming flag storage unit 24, an object generation unit 25, an object pattern storage unit 26, a lock screen. The display unit 27, the authentication processing unit 28, and the standby screen display unit 29 are configured.

  The mode switching unit 20 switches between the privacy mode and the normal mode based on the operation signal from the operation unit 120. In the privacy mode, transmission / reception mails and outgoing / incoming histories with a contact designated in advance by the user as a member to be concealed are not displayed. In addition, user authentication is required when shifting from the privacy mode to the normal mode. For example, password authentication or fingerprint authentication is performed as user authentication.

  When the cellular communication unit 110 receives a communication signal, the transmission source comparison unit 21 compares the transmission source of the communication signal with the sender information held in the sender information storage unit 22, and the comparison result Is output to the reception notification unit 23. The sender information storage unit 22 holds sender information registered by the user. For example, a contact e-mail address or telephone number is stored in association with the sender name. The sender information storage unit 22 holds sender information together with identification information of the normal member and the secret member. The secret member is a member to be concealed designated in advance by the user, and sender information not designated as the secret member is held as a normal member.

  The transmission source comparison unit 21 validates the secret reception flag held in the secret reception flag storage unit 24 when the transmission source of the communication signal matches the sender information of the secret member. That is, when a communication signal is received from a secret member, the secret incoming flag is validated.

  Further, the transmission source comparison unit 21 invalidates the secret incoming flag when the user views the e-mail or the incoming call history received from the secret member. The secret incoming flag storage unit 24 holds such a secret incoming flag. The secret incoming flag is invalidated in the initial state.

  The reception notification unit 23 is a first reception notification unit that performs reception notification by controlling the display control unit 140 or the LED indicator 11 when a communication signal is received. In the privacy mode, when the transmission source of the communication signal matches the sender information of the normal member, the sender information is displayed on the screen as a reception notification.

  If the transmission source of the communication signal is not registered in the sender information storage unit 22, the telephone number or mail address of the transmission source extracted from the communication signal is displayed on the screen as a reception notification. However, when the communication signal is received, if the backlight is turned off, reception notification for turning on the LED indicator is performed. On the other hand, if the transmission source of the communication signal matches the sender information of the secret member, reception notification is not performed.

  In the normal mode, even when the transmission source of the communication signal matches the sender information of the secret member, the sender information is displayed on the screen as a reception notification. When the transmission source of the communication signal matches the sender information of the normal member, or when it does not match the sender information of the normal member or the secret member, the same processing as that in the privacy mode is performed.

  The object generation unit 25 generates an object for reception notification based on the secret incoming flag held by the secret incoming flag storage unit 24. The object is a display object that is displayed as a part of a moving image on a resumption screen that is displayed after the backlight is turned on, for example, a lock screen, and is generated based on pattern information that the object pattern storage unit 26 holds. . For example, a green fluorescent pattern that moves along the periphery of the lock screen is displayed as an object.

  The object includes a secret object for notifying that an incoming call has been received from a secret member, and a normal object for notifying that an incoming call has been received from a sender whose normal member or sender information is not registered. . The object pattern storage unit 26 holds two or more pieces of pattern information for generating a secret object and a normal object.

  The object generation unit 25 generates a normal object when the secret incoming flag is invalid. On the other hand, when the secret incoming flag is valid, a secret object is generated. The secret object is displayed in a different display mode from the normal object on the lock screen. For example, a secret object has a longer display time than a normal object.

  The lock screen display unit 27 displays a lock screen on the touch panel 13 based on a user operation while the backlight of the touch panel 13 is turned off. The lock screen is a resumption screen that is displayed after the backlight is turned on when power supply to the touch panel 13 is resumed. The state where the lock screen is displayed is a locked state for preventing an erroneous operation of the touch panel 13. In such a locked state, by performing a predetermined unlocking operation, the locked state can be released and the standby screen can be displayed.

  The lock screen display unit 27 displays the normal object or secret object generated by the object generation unit 25 on the lock screen immediately after the display of the lock screen is started. That is, the lock screen display unit 27 is a second reception notification unit that notifies that a communication signal has been received from a secret member by displaying a secret object on the lock screen.

  The normal object and the secret object are displayed for a fixed time after the display of the lock screen is started. For example, a normal object and a secret object are displayed for about 1 to 2 seconds. In addition, the normal object and the secret object are made up of images that are separate from the screen components constituting the lock screen. Alternatively, the normal object and the secret object can be obtained by performing image processing on a screen component that forms the lock screen, for example, a part of the background image.

  When the lock screen display unit 27 displays a secret object when a user operation for turning on the backlight is performed during a period other than the communication standby state and the lock screen is displayed, the lock screen display unit 27 indicates that there is an incoming call from the secret member. Notice. The communication standby state is a state of waiting for outgoing and incoming calls, a state where a mobile phone line is connected, that is, a state where the terminal is registered in the line network, and a reception level even if it is out of service area. And waiting for connection to a mobile phone line. In periods other than this communication standby state, the period from when the main power is turned on to the transition to the communication standby state, and from when the main power supply is turned off to when the main power is turned off until the shutdown is performed. There are a period and a period in which the mobile phone function is turned off. When a user operation to turn on the backlight is performed during a period other than such a communication standby state and the lock screen is displayed after the backlight is turned on, a secret member has received an incoming call due to the display of the secret object. Will be notified. For this reason, it is possible to recognize that there is an incoming call from the secret member even during a period other than the communication standby state.

  When the locked state is released, the standby screen display unit 29 displays a standby screen on the touch panel 13 instead of the lock screen. The standby screen is a screen displayed on the touch panel 13 in a state where the telephone function of the portable information terminal 1 is effective and a telephone call can be received. If an e-mail or the like arrives while the standby screen is displayed, the incoming screen is displayed, or if an application program designated by the user is activated, an application program execution screen is displayed.

  The authentication processing unit 28 performs user authentication by performing a predetermined operation on an arbitrary screen. Here, the predetermined operation is, for example, a drag operation for dragging a status bar provided in the screen downward, and a long press operation for long-pressing a setting icon in the notification panel displayed on the screen by this drag operation. And a code input operation for inputting an authentication code. These operations are performed in order, and if the input authentication code matches the registration code registered in advance, the authentication processing unit 28 determines that the user authentication is successful, cancels the privacy mode, and shifts to the normal mode. The mode switching unit 20 is instructed as follows.

  4 to 6 are explanatory diagrams showing an example of the operation of the portable information terminal 1 of FIG. 2, in which the objects A <b> 1 to A <b> 3 are displayed on the lock screen 30. 4 to 6, the objects A1 to A3 are indicated by broken lines. FIG. 4A shows a state at the start of display of the object A1, and FIG. 4B shows a state in which a predetermined time has elapsed from FIG. 4A.

  When the user presses the operation key 15c while the backlight of the touch panel 13 is turned off, the backlight is turned on and the lock screen 30 is displayed. On this lock screen 30, an unlock button 31 for releasing the lock state is displayed. If the unlock button 31 is dragged downward, the locked state is released and a standby screen is displayed.

  The display of the object A1 is started immediately after the lock screen 30 is displayed, and is ended when a certain time has passed. In the display example shown in FIG. 4A, the object A <b> 1 is composed of a band-shaped pattern having a certain length formed along the upper end and the upper left end of the lock screen 30. This object A1 moves counterclockwise along the peripheral edge of the lock screen 30, as shown in FIG.

  FIG. 5 shows an object A2 having a display pattern different from that in FIG. FIG. 5A shows a state when the display of the object A2 is started, and FIG. 5B shows a state where a predetermined time has elapsed from FIG. 5A.

  The object A2 is a green fluorescent pattern formed so as to extend vertically at the left end and the right end of the lock screen 30, respectively, and the width near the center is wider than the upper end and the lower end. As shown in FIG. 5B, the object A2 protrudes to the center of the screen with the passage of time, gradually increases in width and becomes longer in the vertical direction.

  FIGS. 6A and 6B show an object A3 having a display pattern different from those in FIGS. FIG. 6A shows a state at the start of display of the object A3, and FIG. 6B shows a state in which a predetermined time has elapsed from FIG. 6A.

  The object A3 includes a downwardly convex green fluorescent chevron pattern formed at the upper left corner and the upper right corner of the lock screen 30, and an upward convex green fluorescent color formed at the lower left corner and the lower right corner of the lock screen 30. It consists of a Yamagata pattern. In the state shown in FIG. 6A, the left half of the chevron pattern formed at the upper left corner and the lower left corner of the lock screen 30 and the right half of the chevron pattern formed at the upper right corner and the lower right corner of the lock screen 30 Is also not displayed. As shown in FIG. 6B, these objects A3 move from one end to the other end along the upper or lower end of the lock screen 30, respectively.

<Object setting screen 40>
FIG. 7 is a diagram showing an example of the operation of the portable information terminal 1 in FIG. 2, in which an object setting screen 40 is shown. In the figure, (a) shows the case where the display pattern of the secret object is set, and (b) shows the case where the display pattern of the normal object is set. When setting the display pattern of a normal object, one can be arbitrarily selected from three display patterns “pattern 1” to “pattern 3” having different object shapes and the like. For example, if a touch operation is performed on the “effect pattern” display field, a display pattern selection screen is displayed.

  On the other hand, when setting the display pattern of the secret object, one can be arbitrarily selected from the five display patterns “pattern 1” to “pattern 5”. “Pattern 4” and “Pattern 5” are display patterns unique to the secret object. In addition to the effect pattern, the object setting screen 40 includes display fields for display time, luminance, moving speed, and display width.

  If the display column of “display time” is selected by a touch operation, a display time selection screen is displayed. When a predetermined display time elapses from the start of object display, the object display ends and the object is not displayed on the lock screen. Such a display time can be changed in stages by selecting one of “long”, “standard”, and “short” on the selection screen.

  If the “luminance” display field is selected, a luminance selection screen is displayed. The brightness indicates the relative brightness of the object with respect to the other display areas of the lock screen 30. Such brightness can be changed in a stepwise manner by selecting any one of “bright”, “standard”, and “dark” on the selection screen.

  If the “moving speed” display field is selected, a moving speed selection screen is displayed. The moving speed indicates the moving speed of the object moving on the lock screen 30. Such a moving speed can be changed in stages by selecting one of “fast”, “standard”, and “slow” on the selection screen.

  If the display column of “display width” is selected, a display width selection screen is displayed. The display width indicates the width of the object. Such a display width can be changed in stages by selecting any one of “wide”, “standard”, and “narrow” on the selection screen.

  When the same setting as the effect pattern set in the normal object is selected for all items of the secret object, the user cannot identify the normal object and the secret object. For this reason, when such a setting is selected, an error is displayed and a message prompting to change the setting of the secret object is displayed.

  Steps S101 to S107 in FIG. 8 are flowcharts showing an example of an operation when an incoming mail is received in the portable information terminal 1 in FIG. This processing procedure is started when the cellular communication unit 110 receives an e-mail.

  First, the transmission source comparison unit 21 compares the transmission source of the received electronic mail with the sender information of the secret member (step S101). At this time, if the sender of the e-mail matches the sender information of the secret member, the sender comparison unit 21 validates the secret incoming flag in the secret incoming flag storage unit 24 and ends this process (step S102). ).

  On the other hand, if the transmission source of the received electronic mail does not match the sender information of the secret member, it is determined whether or not the backlight of the touch panel 13 is lit (step S103). At this time, if the backlight is on, the transmission source comparison unit 21 compares the transmission source of the received electronic mail with the sender information of the normal member (step S104). If the sender of the e-mail matches the sender information of the normal member, the reception notifying unit 23 sends the e-mail address of the sender that is associated with the e-mail address in the sender information storage unit 22. Registration information such as a person's name is displayed on the touch panel 13 as a reception notification, and this process ends (step S105).

  On the other hand, when the transmission source of the received electronic mail does not match the sender information of the normal member, the reception notification unit 23 displays the mail address of the transmission source on the touch panel 13 as reception notification, and this process is performed. The process ends (step S107). If it is determined in step S103 that the backlight is turned off, the reception notification unit 23 turns on the LED indicator 11 as a reception notification, and the process ends (step S106).

  Steps S201 to S203 in FIG. 9 are flowcharts showing an example of an operation at the time of mail browsing in the portable information terminal 1 in FIG. This processing procedure is started when the user performs a browsing operation on the received mail in the normal mode. First, the secret incoming flag in the secret incoming flag storage unit 24 is read (step S201). At this time, if the secret incoming flag is invalid, this processing is immediately terminated.

  On the other hand, when the secret incoming flag is valid, it is determined whether or not the operation is a browsing operation for the e-mail received from the secret member (step S202). The received mail from the secret member is a confidential mail. If it is not an operation for browsing the confidential mail, this process ends. On the other hand, in the case of the browsing operation for the confidential mail, the secret incoming flag in the secret incoming flag storage unit 24 is invalidated, and this process ends (step S203).

  Steps S301 to S308 in FIG. 10 are flowcharts showing an example of operations after the backlight is turned on in the portable information terminal 1 in FIG. This processing procedure is started when the user presses the operation key 15c while the backlight of the touch panel 13 is turned off in the privacy mode. First, the lock screen display unit 27 displays the lock screen 30 (step S301).

  Next, the object generation unit 25 reads the secret incoming flag from the secret incoming flag storage unit 24 (step S302). At this time, if the secret incoming flag is valid, the lock screen display unit 27 starts displaying the secret object immediately after the lock screen 30 is displayed (step S303). The display of the secret object is continued for a certain time T1, and when the certain time T1 has elapsed from the start of the display of the lock screen 30, the display of the secret object is ended (steps S304 and S305).

  On the other hand, when the secret incoming flag is invalid, the display of the normal object is started immediately after the lock screen 30 is displayed (step S307). The display of the normal object is continued for a predetermined time T2, and when the predetermined time T2 has elapsed from the start of the display of the lock screen 30, the display of the normal object is ended (steps S308 and S305).

  Next, the standby screen display unit 29 displays the standby screen and ends this processing (step S306). The normal object and the secret object are displayed on the lock screen 30, but are not displayed on the standby screen.

  According to the present embodiment, when a communication signal is received from a transmission source other than the secret member, the reception notification unit 23 performs reception notification, whereas when a communication signal is received from the secret member, a reception notification unit 23 does not perform reception notification. For this reason, it can suppress that the third party detects that there was an incoming call from the secret member. Also, objects with different display patterns are displayed on the lock screen 30 when the incoming call is from a secret member and when the incoming call is from a transmission source other than the secret member. For this reason, the user can easily identify whether there is an incoming call from the secret member. Furthermore, since the secret object is displayed for a certain period of time immediately after the lock screen 30 displayed after the backlight is turned on, it is difficult for a third party to detect that there is an incoming call from the secret member.

  In this embodiment, an example in which the lock screen 30 is displayed after the backlight is turned on has been described. However, the present invention does not have a locked state or can disable the lock function. Can also be applied. For example, the present invention can be applied to a display that displays a standby screen after the backlight is turned on.

  The standby screen display unit 29 displays a standby screen based on a user operation. For example, when the operation key 15b is pressed while a screen different from the standby screen, for example, an electronic mail browsing screen is displayed, the standby screen is displayed. The standby screen display unit 29 displays the standby screen immediately after the backlight is turned on when the standby screen is displayed immediately before the backlight is turned off.

  When the standby screen is displayed after the backlight is turned on, the standby screen display unit 29 displays the normal object or secret object generated by the object generation unit 25 on the standby screen immediately after the standby screen is displayed. For example, when the standby screen is displayed immediately before the backlight is turned off, the display of the object is started immediately after the standby screen is displayed after the backlight is turned on. If a screen other than the standby screen is displayed immediately before the backlight is turned off, the screen that was displayed immediately before the backlight is turned off is displayed after the backlight is turned on. In this case, if the operation key 15c is operated, the standby screen is displayed and the display of the object is started. The normal object or the secret object is displayed for a predetermined time after the display of the standby screen is started.

  After the backlight is turned on, instead of displaying the normal object or the secret object on the standby screen displayed first, the standby screen is displayed until the predetermined number of times of 2 or more is reached after the backlight is turned on. A configuration may be adopted in which a normal object or a secret object is displayed on the standby screen every time.

  In the present embodiment, an example in which two unique patterns can be selected as the display pattern of the secret object has been described.

The secret object is configured to be displayed for a certain time immediately after the screen 30 is displayed. According to such a configuration, it is possible to suppress a third party from detecting that there is an incoming call from a secret member. Different objects are displayed on the lock screen 30 when the incoming call is from a secret member and when the incoming call is from a transmission source other than the secret member. For this reason, the user can easily identify whether there is an incoming call from the secret member. Furthermore, since the object is displayed for a certain period of time immediately after the lock screen 30 displayed after the backlight is turned on, it is difficult for a third party to detect that there is an incoming call from the secret member.

  In addition to the above configuration, the portable information terminal 1 according to the second aspect of the present invention is configured such that the secret object has a different display time compared to the normal object. According to such a configuration, the secret object and the normal object can be easily identified without being detected by a third party.

  In addition to the above configuration, the portable information terminal 1 according to the third aspect of the present invention is configured such that the normal object and the secret object move along the peripheral edge of the lock screen 30. According to such a configuration, since the normal object and the secret object are not conspicuous, it is possible to make it difficult for a third party to detect that there is an incoming call from the secret member.

  In addition to the above configuration, the mobile information terminal 1 according to the fourth aspect of the present invention displays the lock screen 30 when the lock screen display unit 27 performs a user operation to turn on the backlight during a period other than the communication standby state. In this case, the display of the secret object is configured to notify that there is an incoming call from the secret member. According to such a configuration, it is possible to recognize that there is an incoming call from the secret member even during a period other than the communication standby state.

  The portable information terminal 1 according to the fifth aspect of the present invention includes a reception notification unit 23 that performs reception notification when a communication signal is received, and a power source that turns on the backlight based on a user operation while the backlight of the display is turned off. The supply unit 130 displays a standby screen, displays a standby screen display unit 29 that displays either a normal object or a secret object as part of a moving image on the standby screen after the backlight is lit, and sender information of a secret member. A sender information storage unit 22 to hold, and a transmission source comparison unit 21 that compares the transmission source of the communication signal and the sender information of the secret member when a communication signal is received, and the transmission source of the communication signal is If it does not match the sender information, the reception notification unit 23 performs reception notification, and the standby screen display unit 29 displays the standby screen. Immediately after the display, the normal object is displayed for a certain period of time, and when the transmission source of the communication signal matches the sender information, the reception notification unit 23 does not perform reception notification, and the standby screen display unit 29 immediately after displaying the standby screen. The secret object is configured to be displayed for a certain period of time. According to such a configuration, different objects are displayed on the standby screen when the incoming call is from a secret member and when the incoming call is from a transmission source other than the secret member. For this reason, the user can easily identify whether there is an incoming call from the secret member. Furthermore, since the object is displayed for a certain period of time immediately after the standby screen displayed after the backlight is turned on, it is difficult for a third party to detect that there is an incoming call from the secret member.
