  FIG. 4 is a schematic block diagram illustrating a configuration example of the function realization unit by the CPU of the main control unit 26. In addition, this function realization part may be comprised by hardware logics, such as a circuit, without using CPU.

  As illustrated in FIG. 4, the CPU of the main control unit 26 functions as at least an operation content acquisition unit 41, a system state management unit 42, an image acquisition unit 43, and an image output unit 44 by an externally acquired image utilization program. Each of the units 41 to 44 uses a required work area of the RAM as a temporary storage location for data.

  The operation content acquisition unit 41 receives the output of the touch sensor 28 and acquires the content of the input operation on the display screen. The output of the touch sensor 28 includes at least information on the contact position on the display screen by the user. Based on the information on the contact position received from the touch sensor 28 and the information on the time at which the information is received, the operation content acquisition unit 31 performs a press, release, press and hold on the display screen. It is determined whether the input operation is a slide, flick, single tap, double tap or the like, and the contents of the input operation and the information of the contact position are output.

  Further, the operation content acquisition unit 31 determines whether the hard key 15 is pressed short, long, or very long, and outputs the determined result.

  Here, for each input operation on the user's display screen, the press refers to the transition operation from the non-contact state to the contact state, the release refers to the transition operation from the contact state to the non-contact state, and press and hold is A so-called long press operation that maintains a contact state for a predetermined time (for example, 1 second) after pressing is assumed. In addition, the slide means an operation of moving the contact position at a speed lower than a predetermined speed while maintaining the post-press contact state, and the flick is released after the contact position is moved at a predetermined speed or more while the post-press contact state is maintained. Let's say movement. The single tap is a so-called click operation that is released within a predetermined time (for example, 1 second) after pressing, and the double tap is a so-called single tap that is again performed within a predetermined time (for example, 0.5 second) after the single tap. It shall be a double click operation.

  The system state management unit 42 manages the system state in at least one of a lock state that is a system state for preventing an erroneous operation and a standby state that is a system state at the time of standby. The locked state is a system state in which an input operation via the hard key 15 and the touch sensor 28 is invalid except for a predetermined input operation (hereinafter referred to as touch lock). In the present embodiment, an example will be described in which the system state management unit 34 manages the system state in either the off-screen lock state or the on-screen lock state as the lock state.

  The image acquisition unit 43 acquires from the web server 6 set in advance among the web servers 6 storing the image information via the Internet network 4 every predetermined time. Note that “every predetermined time” includes at least one of every predetermined time interval (for example, every 2 hours) and every predetermined time (for example, every day at 1 pm, etc.).

  Specifically, the image acquisition unit 43 receives the output of the timer control unit 32, accesses the web server 6 corresponding to a service set in advance every predetermined time, acquires image information, and stores it in the storage unit 25. Remember.

  Note that the image acquisition unit 43 may acquire only image information that matches the keyword by using a keyword preset by the user. As a keyword, for example, an animal (such as a panda or a crest) or a person (such as a celebrity name) can be used. The image acquisition unit 43 may store the keyword and service information in association with each piece of image information in the storage unit 25.

  When the system state management unit 42 receives information indicating that the system state has shifted from the other system state (for example, the off-screen lock state or the standby state) to the display unit 27, The image information stored in the storage unit 25 is output. Upon receiving the image information output from the image output unit 44 in the on-screen lock state, the display unit 27 displays an image based on this image information as a background image.

  An image output to the display unit 27 in the on-screen locked state by the image output unit 44 (hereinafter referred to as a locked background image) can be arbitrarily set from the own device acquired image and the externally acquired image. When an externally acquired image is set as a background image at the time of locking, an image associated with a predetermined keyword or a predetermined service may be set. At this time, a plurality of keywords and services may be designated.

  Further, when an externally acquired image is set as the background image at the time of locking, the image output unit 44 orders in accordance with a predetermined condition (for example, alphabetical order of image file, order of acquisition time, random, etc.), and one image according to this order. May be extracted and displayed, or may be sequentially displayed (slide show display) every predetermined time (for example, 5 seconds). The order of the externally acquired images may be redone every time the externally acquired image is acquired (updated) or every time the system is restarted.

  Note that the image output unit 44 may output image information different from the image information output as the background image at the time of the previous lock when shifting from the other system state to the on-screen lock state. In this case, the user can see different background images at the time of locking, and can use the mobile phone 1 with more enjoyment. In this case, the image output unit 44 may store information indicating the image information output last time in a required work area of the RAM and check this information at the next output time.

  Further, the image output unit 44 may output the image information after changing the image information so that the image information is reduced to fit the width of the display screen. For example, when the screen size is 480 dots × 854 dots and an image of 600 dots × 800 dots is displayed, the image information is changed so as to be reduced so that the width fits in 480 dots and output. Further, the image information may be output after being changed so that the display screen is enlarged. On the other hand, when the number of pixels of the image information to be output is low, if the image is enlarged and displayed, the image display may become rough. Therefore, when the number of pixels of the image information to be output is less than or equal to a predetermined number of pixels, or when the number of pixels of the image information to be output is less than a predetermined ratio with respect to the number of pixels of the display screen, the enlargement ratio is within a predetermined range. The image information may be output without being reduced, reduced, or enlarged or reduced. At this time, a vacant portion that cannot be filled with an image based on the output image information is generated on the display screen. The background image information stored in advance in the storage unit 25 is used as background image data of the image information. It may be output. When outputting the background image image information, even if the background image is locked with a small number of pixels, the surrounding blank can be filled with the background image data, and the uncomfortable feeling can be reduced.

  FIG. 5 is a diagram for explaining state transitions between the system states of the off-screen lock state, the on-screen lock state, and the standby state.

  The off-screen lock state is a system state in which the touch screen is locked and the display screen output of the display unit 27 is stopped (see the left in FIG. 5). In the off-screen lock state, for example, only an input operation to the hard key 15 is accepted, and the input operation via the touch sensor 28 is invalidated.

  The on-screen lock state is a state in which the display unit 27 displays an image when it is touch-locked and receives image information output from the main control unit 26 (see the center of FIG. 5). In the on-screen lock state, for example, unlock guide information 51 is displayed, and input operations through the touch sensor 28 except for input operations in accordance with the unlock guide information 51 are invalidated.

  FIG. 6 is an explanatory diagram showing a state when transitioning from the on-screen lock state to the standby state. As shown in FIG. 6, the user can shift from the on-screen lock state to the standby state by performing an input operation (slide or flick) in accordance with the lock release guide information 51.

  In the following description, an example in which an image associated with the keyword “panda” among externally acquired images is set as a background image at the time of locking will be described.

  When the operation content acquisition unit 41 determines that the hard key 15 is pressed for a short time in the off-screen lock state, the system state management unit 42 shifts the system state to the on-screen lock state (from left to center in FIG. 5). See transitions). When the image output unit 44 receives information that the system state management unit 42 has shifted from the off-screen lock state to the on-screen lock state, the image output unit 44 uses the keyword “of the image information stored in the storage unit 25 for the display unit 27. The image information of the externally acquired image associated with “Panda” is output.

After outputting one piece of image information of the externally acquired image associated with the keyword “panda”, a slide show is displayed by sequentially repeating outputting the next piece of image information after a predetermined time (for example, 5 seconds) has elapsed.

  FIG. 8 is an explanatory diagram showing a state in which a service that provides an externally acquired image can be easily accessed from an on-screen lock state.

  As illustrated in FIG. 8, the system state management unit 42 may display an icon (service icon) 53 indicating a service associated with the lock background image displayed in the on-screen lock state. For example, when an image associated with the service “service A” is set as the background image at the time of locking, the service icon 53 indicating “service A” is displayed (see the left in FIG. 8).

  When the service icon 53 is touched (see the center in FIG. 8), the system state management unit 42 displays an icon for accessing the service A in the vicinity of the service icon 53. FIG. 8 shows an example in which the refresh icon 54 is displayed near the right side of the service icon 53 and the access icon 55 is displayed near the left side (see the right side of FIG. 8).

  FIG. 9 is a diagram for explaining functions assigned to the refresh icon 54.
