Description

  The present invention relates to a terminal device and a program for displaying map data on a display means.

  There is a terminal device equipped with a navigation function that acquires position information such as its own position and the position of an object (for example, a destination or a meeting partner) and displays map data including the position information on a display unit. In such a terminal device, position information is periodically acquired, map data is updated based on the position information, and the updated map data is updated and displayed on the display unit.

However, since power is required to update the display, there is a problem that power consumption for updating the display becomes large if update display is frequently performed.
As a method of reducing the power consumption of the terminal device, if it is determined that the screen should not be viewed by the operator (user) based on the moving status of the moving object or the map data, the brightness of the screen is lowered. Or a technique for deleting the screen display has been proposed (see, for example, Patent Document 1).

JP 2007-132870 A

FIG. 12 is a flowchart for explaining an example of the operation of the initial process described above.
The mobile phone 10 sets the timer values of the movement detection timer, the position acquisition timer, and the display update timer stored in the timer value storage unit 102c to 3 seconds (step C1) and stores them in the movement state (previous 3). (Movement amount per second) is detected, stored in the movement state storage unit 102b in association with the detected date (step C2), the timer value of the movement detection timer is read from the timer value storage unit 102c, and the movement detection timer is set. Start (step C3). If the amount of movement for the previous 3 seconds cannot be detected because, for example, 3 seconds have not elapsed since the navigation function was activated, the amount of movement for 3 seconds is detected based on the amount of movement for the time that can be detected ( (Calculation).

  Next, the cellular phone 10 acquires its own position information and the position information of the target specified by the target specifying operation, and stores it in the position information storage unit 102a in association with the acquired date and time (step C4). Then, the timer value of the position acquisition timer is read from the timer value storage unit 102c, and the position acquisition timer is started (step C5). Thereafter, the cellular phone 10 performs display update processing A (step C6), and ends this flowchart. The display update process A will be described later.

FIG. 13 is a flowchart for explaining an example of the operation of the movement state determination process described above.
The mobile phone 10 detects the movement state (movement amount for the last 3 seconds), stores it in the movement state storage unit 102b in association with the detected date and time (step D1), and stores the timer value of the movement detection timer as a timer value. The movement detection timer is started by reading from the unit 102c (step D2).
Next, the cellular phone 10 determines whether or not the style indicating the usage state of the housing is an open style (step D3). If it is determined that it is an open style (YES in step D3), it is determined whether or not the battery remaining amount flag is “1” (step D4). When it is determined that the remaining battery level flag is not “1” (that is, the remaining battery level is sufficient) (NO in step D4), it is determined whether the power saving flag is “1”. (Step D5).

  If it is determined in step D3 that it is not an open style (that is, it is a closed style) (NO in step D3), or the power saving flag is not “1” in step D5 (that is, the power saving operation mode is set). If it is determined that the state is not present (NO in step D5), this flowchart is terminated. On the other hand, if it is determined in step D4 that the remaining battery level flag is “1” (ie, the remaining battery level is low) (YES in step D4), or the power saving flag is set to “1” in step D5. "(That is, the state set in the power saving operation mode) (YES in step D5), the mobile phone 10 determines that the movement state detected in step D1 is the control content. It is determined which item of the control content stored in the storage unit 102e corresponds (step D6), and it is determined whether it corresponds to the control content item whose current flag is “0” (step D7). .

  Does not correspond to the item of control content with the current flag “0” (ie, corresponds to the item of control content with the current flag “1”) = no change from the movement state determined in the previous movement state determination process ) (NO in step D7), this flowchart is ended. On the other hand, it corresponds to the control content item whose current flag is “0” (that is, this time is the first movement state determination process or there is a change from the movement state determined in the previous movement state determination process). (YES in step D7), the mobile phone 10 sets the current flag of the corresponding item of the control content stored in the control content storage unit 102e to “1”, otherwise The current flag of the control content item is set to “0” (step D8).

For example, if the read display update interval is “2 minutes”, the timer value of the display update timer is set to “2 minutes”. If the read display update interval is “fixed display”, the timer value of the display update timer is set to “infinity”.

  Next, regarding the position information acquisition timing stored in the position information acquisition timing storage unit 102d, the mobile phone 10 determines whether or not the item whose setting flag is “1” is “linked to the display update interval” ( That is, it is determined whether or not the position information acquisition timing is set to “linked to the display update interval” (step D11). When it is determined that the item whose setting flag is “1” is “linked to the display update interval” (YES in step D11), the mobile phone 10 sets the display update interval read in step D9. The timer value is set as the timer value of the position acquisition timer in the timer value storage unit 102c (step D12).

  For example, if the read display update interval is “2 minutes”, the timer value of the position acquisition timer is set to “2 minutes”. If the read display update interval is “fixed display”, the timer value of the position acquisition timer is set to “infinity”. On the other hand, it is determined that the item whose setting flag is “1” is not “linked to the display update interval” (that is, the item whose setting flag is “1” is “not linked to the display update interval”). In that case (NO in step D11), the process proceeds to step D13.

  Next, the mobile phone 10 acquires its own position information and the position information of the target specified by the target specifying operation, and stores it in the position information storage unit 102a in association with the acquired date and time (step D13). Then, the timer value of the position acquisition timer is read from the timer value storage unit 102c, and the position acquisition timer is started (step D14). After that, the cellular phone 10 performs display update processing B (step D15), indicating that the display update interval has been changed due to the change in the moving state, that the sound output from the sound speaker 109a, the light output from the LED 109b, This is notified by vibration generation by the vibration motor 109c, message display by the display unit 106, etc. (step D16), and this flowchart is ended. The display update process B will be described later.

FIG. 14 is a flowchart for explaining an example of the operation of the display process described above.
The mobile phone 10 determines whether or not the style indicating the usage state of the housing is an open style (step E1). If it is determined that it is an open style (YES in step E1), it is determined whether or not the battery remaining amount flag is “1” (step E2). If it is determined that the remaining battery level flag is not “1” (that is, the remaining battery level is sufficient) (NO in step E2), it is determined whether or not the power saving flag is “1”. (Step E3).

  If it is determined in step E1 that it is not an open style (ie, it is a closed style) (NO in step E1), or the power saving flag is not “1” in step E3 (that is, the power saving operation mode is set). If it is determined that it is not present (NO in step E3), the mobile phone 10 performs display update processing A (step E4), and ends this flowchart. On the other hand, if it is determined in step E2 that the remaining battery level flag is “1” (that is, the remaining battery level is low) (YES in step E2), or the power saving flag is set to “1” in step E3. Is determined (that is, the power saving operation mode is set) (YES in step E3), the mobile phone 10 performs display update processing B (step E5). The flowchart ends. The display update process A and the display update process B will be described later.
