Abstract

PROBLEM TO BE SOLVED: To increase screen display speed at key depression and decrease power consumption when a terminal is not used by a user.SOLUTION: In a terminal with a touch panel, when the terminal detects that a distance between the touch panel and a pointer of a finger of a user or a touch pen is between a first threshold and a second threshold, it reads program data from a first memory device to a second memory device whose reading speed is faster than that of the first memory device. At this time, a processor does not execute the processing. When the terminal detects that the distance from the pointer is less than the first threshold, the processor reads the program data from the second memory device if the program data is in the second memory device and executes the processing.

Description

  The present invention relates to a mobile information terminal such as a mobile phone that speeds up screen display with a touch panel by reading a program and data necessary for screen display before a user presses a key into a memory with high access speed in advance. .

  In the conventional mobile terminal, the program and data required for screen display are stored in ROM (Read Only Memory), and the user reads from the ROM after pressing the key and performs display processing. Time is required and operability is deteriorated.

  As a means for speeding up the screen display, a menu screen table with priority of Patent Document 1 is prepared, and the next screen to be selected when there is a margin in the menu screen playback operation is given priority. There is known a method of speeding up the output of a menu screen by reading the data from the optical disk in advance to the RAM according to the timetable and reading the screen data from the RAM if the menu screen is on the RAM when the user operates.

  Further, in Patent Document 2, before an operator performs a pressing operation on the touch panel unit, a display component corresponding to the pressing operation is predicted in advance, and an enlarged display of the component and an audio guide are provided to perform an operation. The operability for the user can be improved.

  Further, in Patent Document 3, when the folding portable terminal detects that the shell has been opened 360 degrees, it starts the TV receiver and the TV display application program and outputs a TV video signal to the main display. This makes it possible to improve operability.

  However, in Patent Document 1, since the reading process is always performed when there is no operation, the number of times of reading increases and the current consumption increases.

  Further, in Patent Document 2, when the present technology is applied to a mobile terminal, a sensor operates even in a case where the user does not intend to operate, and a useless predictive operation is performed. There is.

  Regarding Patent Document 3, only a predetermined function can be activated, and a function to be charged is activated in a case not intended by the user. Therefore, applicable functions are limited, and other than the folding terminal. There was a problem that this technology could not be applied.

  A portable terminal device according to the present invention includes a housing, a display unit disposed on a surface of the housing and displaying an icon, a display surface of the display unit, a position of the pointer on the display surface, and a pointer A touch panel unit for detecting a distance between the first memory device and a display surface; a first memory device in which program data related to the icon is stored; a second memory device having a higher access speed than the first memory device; A processor that executes program data; and a battery that supplies power to the processor, the display unit, the touch panel unit, the first memory device, or the second memory device, and the position is the icon And if the distance is between a first threshold and a second threshold greater than the first threshold, the program data From the first memory device to the second memory device, the processor corresponds to the second memory if the position corresponds to the icon and the distance is less than the first threshold. The program data moved to the device is executed.

  With this configuration, the program data required for display processing is accessed from the first memory device with slow access speed before the final selection of the user (the pointer corresponds to the icon and the distance is smaller than the first threshold). Since the program data is read from the second memory device after reading to the second memory device with high speed and after the final selection, it is possible to shorten the time from the final selection until the program data is executed and displayed. It becomes.

In the portable information terminal of the present invention, when the position corresponds to the icon and the distance is between a first threshold value and a second threshold value that is greater than the first threshold value, While moving program data from the first memory device to the second memory device, the processor does not read the program data from the second memory device, the position corresponds to the icon, and the distance However, if the value is smaller than the first threshold, the processor reads out and executes the program data from the second memory device. With this configuration, the program data is not executed and is read into the second memory data. When stopping operation before final selection, unnecessary execution processing is not performed, so power consumption is reduced and battery life is improved. Is possible.

  In the portable information terminal of the present invention, the second threshold value is substantially zero, and when the pointer is smaller than the first threshold value, the pointer touches the touch panel.

  With this configuration, the program data is read to the second memory device, but the processor is not executing, and the state immediately before touching the touch panel unit is assigned, and the processor is more than the second memory device. It is possible to assign a state of touching the touch panel unit to a state of executing program data.

  In the portable information terminal of the present invention, the program data is data of a program that gives a change to the display unit, and the display unit changes when the processor executes the program data.

  With this configuration, when the processor executes the program data, the display unit is changed and screen display can be performed.

  Moreover, the portable information terminal of the present invention includes a third threshold value that is greater than the second threshold value, the position corresponds to the icon, and the distance includes the first threshold value and the second threshold value. The program data is moved from the first memory device to the second memory device, the processor does not read the program data from the second memory device, and the location is When the distance corresponds to the icon and the distance is smaller than the first threshold, the processor reads and executes the program data from the second memory device, and the position corresponds to the icon. And when the distance is between a first threshold value and a third threshold value, the program data is transferred from the first memory device to the first threshold value. The processor does not read the program data from the second memory device, the position corresponds to the icon, and the distance is less than the first threshold, the processor Comprises a second state in which the program data is read and executed from the second memory device, and switches between the first state and the second state according to the state of the portable information terminal.

  With this configuration, it is possible to switch between a state in which priority is given to holding the battery of the portable information terminal and a state in which priority is given to speeding up the screen display.

  In the portable information terminal of the present invention, the first threshold value and the second threshold value are substantially the same.

  With this configuration, in the first state, the processor does not read the program data from the first memory device to the second memory device, and the processor reads the program data from the first memory device. Execute.

  Further, the portable information terminal of the present invention includes an inclination detection unit that detects an angle based on a vertical direction of the casing, and when the angle is within a predetermined range, the portable information terminal is set to the second state, When the angle is out of the predetermined range, the first state is set.

  With this configuration, since the second state can be set only when the user operates the portable information terminal, power consumption can be suppressed when the user does not operate the portable terminal.

  In the portable information terminal of the present invention, the casing can be opened and closed. When the casing is open, the second state is set. When the casing is closed, the first state is set. And

  With this configuration, when the casing is closed, the program data reading process is not performed, so that unnecessary processing when the user does not operate can be suppressed, and power consumption can be suppressed.

  The portable information terminal of the present invention is set to the second state when the remaining capacity of the battery is greater than a predetermined value, and is set to the first state when the remaining capacity is less than the predetermined value.

  With this configuration, when the remaining capacity of the battery is small, the power consumption can be suppressed by setting the first state.

  According to the speed-up of the screen display of the present invention, it is possible to speed up the screen display during operation by reading out the program data necessary for the screen display immediately before the user touches the touch panel unit.

  In addition, by switching between the first state and the second state according to the tilt of the terminal and the remaining battery level, it is possible to suppress power consumption when the user does not intend.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is an overall configuration diagram for speeding up screen display according to the present invention. As shown in FIG. 1, the screen display speeding up in the embodiment of the present invention is performed by the display unit 11, the first memory device 12, the second memory device 13, the processor 14, the battery 15, the tilt detection unit 16, and the open / close detection. The unit 17 is configured.

  The display unit 11 is disposed on the surface of the housing 1 and has a function of displaying menu icon data. A touch panel unit 111 is disposed along the display surface of the display unit 11. The touch panel unit 111 has a function of detecting the distance 21 from the pointer 2 such as a user's finger or a touch pen in two stages, and has a function of detecting the X coordinate and the Y coordinate position on the display surface with the pointer 2.

  The first memory device 12 stores program data 121 for displaying menu icons, and the processor 14 has a function of displaying menu icons on the display unit 11 by reading and executing the program data 121.

  The second memory device 13 is a device that can read data faster than the first memory device 12. Compared with the case where data is read out from the first memory device 12, the icon can be displayed on the display unit 11 at a higher speed when the data is read out from the second memory device 13.

  The processor 14 receives the X coordinate, the Y coordinate, and the distance from the pointer 2 from the touch panel unit 111, and reads the program data 121 from the first memory device to the second memory device 13 in accordance with the distance from the pointer 2. In addition, the program data is executed and display processing on the display unit 11 is performed. The battery 15 has a function of supplying power to each block of the casing and a function of notifying the processor 14 of the remaining battery level.

  The inclination detection unit 16 includes a sensor device, and has a function of detecting the inclination of the terminal and notifying the processor 14. The open / close detection unit 17 has a function of detecting the open / closed state of the terminal and notifying the processor 14.

  FIG. 2 shows the distance 21 between the pointer 2 and the touch panel unit 111 and its threshold value. When the touch panel unit 111 detects that the distance 21 is between the first threshold value 22 and the second threshold value 23, the touch panel unit 111 notifies the processor 14 as an interrupt. Further, when the touch panel unit 111 detects that the distance 21 is smaller than the first threshold value 22, the touch panel unit 111 notifies the processor 14 as an interrupt. The first threshold 22 is infinitely close to 0, and when the distance 21 is smaller than the first threshold 22, it means that the pointer 2 is in contact with the touch panel unit 111, and the user presses the key. It can be considered that it is in a state of being. With this configuration, the program data 121 is read to the second memory device 13 immediately before touching the touch panel unit 111, but the touch panel unit 111 is touched while the processor 14 is not executing the program data 121. Can be assigned to the state in which the processor 14 is executing the program data 121.

  FIG. 3 illustrates a processing flow when it is detected that the distance 21 is between the first threshold value 22 and the second threshold value 23. When the touch panel unit 111 detects that the distance 21 is between the first threshold value 22 and the second threshold value 23 (S3-2), the touch panel unit 111 notifies the processor 14 as an interrupt (S3-3). The processor 14 obtains the X coordinate and the Y coordinate on the touch panel unit 111 of the pointer 2 from the touch panel unit 111, calculates the corresponding icon data (S3-4), and the second memory device 13 has a free space (S3-5) reads program data 121 related to the icon data from the first memory device to the second memory device (S3-6).

  FIG. 4 illustrates a processing flow when it is detected that the distance 21 is smaller than the first threshold value 22. When it is detected that the distance 21 is smaller than the first threshold 22 (S4-2), the processor 14 is notified as an interrupt (S4-3). The processor 14 acquires the X coordinate and the Y coordinate of the pointer 2 on the touch panel unit 111 from the touch panel unit 111, and calculates corresponding icon data (S4-4). When executing the program data 121 related to the icon data, if the program data 121 is read to the second memory device 13 (S4-5), the processor 14 reads the program data 121 from the second memory device 13. Is read out and executed (S4-6). If the program data 121 has not been read to the second memory device 13, the processor 14 reads the program data 121 from the first memory device 12 and executes it (S4-7). 3 and 4, the program data 121 is read from the first memory device 12 to the second memory device 13 before the final selection by the user (distance 21 is smaller than the first threshold 22). Since the program data 121 is read from the second memory device 13 after the final selection, it is possible to shorten the time from the final selection until the program data is executed and displayed. Further, since the program data 121 is not executed when the distance 21 is between the first threshold value 22 and the second threshold value 23, the execution process of the program data 121 is not performed when the operation is stopped before the final selection. Therefore, power consumption can be reduced and battery life can be improved.

  FIG. 5 illustrates the processing flow when the remaining battery level is low. When it is detected that the battery capacity of the battery 15 has become smaller than a predetermined value (S5-2), the processor 14 is notified as an interrupt. At this time, the processor 14 sets the second threshold value 23 to the same value as the first threshold value 22 (S5-3). As a result, reading from the first memory device 12 to the second memory device is not performed, and high-speed screen display is not performed. However, since the processing amount of the processor 14 and the number of memory accesses can be reduced, priority is given to power saving. It becomes a state. When the battery capacity is sufficient, the second threshold value 23 can be set to a value larger than the first threshold value 22 to realize the high-speed display state of FIG. 3 and switch between the power saving priority state and the high-speed display state. Can be used.

  FIG. 6 illustrates a processing flow in the case of detecting the tilt of the terminal and switching the high-speed display state between valid and invalid. The inclination detection unit 16 notifies the processor 14 when the terminal angle is out of the predetermined angle range (S6-2). At this time, the processor 14 sets the second threshold value 23 to the same value as the first threshold value 22 (S6-3), thereby enabling the high-speed display state to be switched between valid and invalid. With this configuration, when it is determined that the user is not operating the mobile terminal due to the tilt of the terminal, high-speed display can be disabled and power consumption can be suppressed.

  FIG. 7 illustrates a processing flow when the open / closed state of the terminal is detected and the valid / invalid state of the high-speed display state is switched. The open / close detection unit 17 notifies the processor 14 of the terminal open / close state (S7-2). At this time, when the terminal is in the closed state (S7-3), the processor 14 sets the second threshold value 23 to the same value as the first threshold value 22 (S7-4), thereby validating / invalidating the high-speed display state. It is possible to switch. With this configuration, when it is determined that the user is not operating the mobile terminal according to the open / closed state of the terminal, high-speed display can be disabled and power consumption can be suppressed.

  As explained in FIG. 5, FIG. 6, FIG. 7, it is possible to switch between the high-speed display state and the power saving priority state according to the battery remaining amount, the terminal angle, and the terminal opening / closing state, and the battery remaining amount is sufficient. Only when the terminal angle is within a predetermined angle range and the terminal is in the open state, the high-speed display state is set.

  The information terminal device according to the present invention can be used in an information terminal including a touch panel.
