  In this embodiment, the information processing apparatus is assumed to be a portable information processing terminal having a touch panel as an information input device. As the portable information processing terminal, a notebook personal computer, a mobile phone, a smartphone, a PDA (Personal Digital Assistant), a navigation device, or the like can be applied. Alternatively, the present invention can be applied to an information processing terminal placed in an ATM (Automated Teller Machine), a credit card authentication device, or other commercial facilities. The information processing terminal is not limited to a portable type, and may be a stationary type.

<Hardware configuration>
With reference to FIG. 1 and FIG. 2, the configuration of a portable information processing terminal (hereinafter simply referred to as a terminal) 100 according to the present embodiment will be described. FIG. 1 is a diagram illustrating the appearance of the terminal 100. FIG. 2 is a block diagram showing the hardware configuration of terminal 100. The terminal 100 includes a housing 110, an antenna 120, a speaker 130, a display unit 210 having a known resistive film type touch panel 140 and a display device 212, a power button 150, a microphone 160, and an LED (Light Emitting Diode) 170.

  A memory card 152 that is a card-like recording medium is detachably attached to the terminal 100 from the outside.

  In addition to the configuration shown in FIG. 1, the terminal 100 includes a sensor unit 220, a processor 230, a display driver 214, a flash memory 250, a RAM (Random Access Memory) 252, a graphic memory 254, a ROM (Read Only Memory) 256, a communication A circuit 260, a signal processing circuit 270, a vibrator 280, and a memory driver 151 for accessing the attached memory card 152 under the control of the processor 230 are provided. The processor 230 includes a CPU (Central Processing Unit) and a timer for timing.

  The sensor unit 220 includes an acceleration sensor, and detects the tilt angle of the terminal 100 from the output of the acceleration sensor.

  The display unit 210 constitutes a part of a display-integrated input device that integrally includes the touch panel 140 and the display device 212. The display device 212 of the display unit 210 corresponds to an LCD (Liquid Crystal Display) panel, and a touch panel 140 is placed on the display surface. The image displayed on the display surface is a visible image that is visible via the touch panel 140. That is, the user can visually recognize the display image on the LCD panel from the outside through the touch panel 140 made of a transparent member. Here, the touch panel 140 employs a resistive film system, but is not limited to this system, and may be, for example, a known electrostatic capacity system or an optical sensor system.

  The display panel constituting the display surface of the display unit 210 is not limited to the LCD described above, and an organic EL display (organic electroluminescence display), an FED (Field Emission Display), or the like may be used.

  The touch panel 140 is touched on the surface by an operating body such as a finger or a dedicated pen (not shown). Here, in order to simplify the explanation, it is assumed that the operating body is a finger. Touch panel 140 outputs an electrical signal corresponding to a position operated by a finger (hereinafter referred to as an operation position) to processor 230.

  Specifically, touch panel 140 includes a transparent glass plate and a film of a resin material that covers the entire surface of the glass plate, and both are arranged so as to sandwich a transparent electrode grid. The electrode grid represents a two-dimensional array surface in which a plurality of electrodes are arranged in a grid pattern. The electrode grid has a size that matches the size of the display area of the LCD panel. When the user touches (presses) a film point on the touch panel 140 with a finger, the film bends due to the pressure, contacts the electrode on the glass surface side, and an electric signal (current) is output through the contacted electrode. .

  The processor 230 measures the voltage division ratio by the resistance of the transparent electrodes on the glass surface and the film surface based on the electrical signal from the touch panel 140, thereby indicating the operation (pressing) position on the electrode grid as a two-dimensional coordinate value (X0, Y0). Detect as. Also, by comparing the level of the electrical signal with a predetermined level, it is detected from the comparison result whether the finger has started touching (touching down) on the touch panel 140, and whether the touch has been completed (touching up). In addition, it is detected whether it is a touch move. The touch move indicates an operation of tracing while touching the film on the touch panel 140 from touch down to touch up immediately after.

  In this way, the touch panel 140 constitutes a part of an operation receiving unit 240 described later for receiving an input by a user operation.

  The LCD panel is configured by two-dimensionally arranging a plurality of electrode elements. Therefore, each electrode element can be specified by the two-dimensional coordinate value (x1, y1). The graphic memory 254 stores image data displayed on the display unit 210 by the processor 230. The image data represents two-dimensional bitmap data having a size that matches the size of the display area of the LCD panel. The display driver 214 generates an electric signal based on each bit value of the image data, and the generated electric signal is an electrode element having a coordinate value (x1, y1) corresponding to the coordinate value (x0, y0) of the bit of the LCD panel. Apply to. As a result, an image according to the image data in the graphic memory 254 is displayed on the display device 212.

  The processor 230 controls the operation of the terminal 100. The processor 230 cooperates with the touch panel 140 to detect a coordinate position indicating the operation position on the touch panel 140, more specifically, coordinate data.

  Specifically, the operation accepting unit 240 of the processor 230 detects an electrode position corresponding to the operation position on the electrode grid based on the electric signal from the touch panel 140, and uses the conversion coefficient in which the detected electrode position is determined in advance. A coordinate data acquisition unit that acquires coordinate data by converting the coordinate values of corresponding points on the touch panel 140. Further, the operation reception unit 240 is based on time-series coordinate data based on electric signals input in time series, and a touch move locus from the start point (touch down) to the end point (immediate touch up) of the operation on the touch panel 140. Has a trajectory detection unit that detects a trajectory composed of a series of coordinate values. The series of coordinate values are time-series coordinate values according to the detection order. Note that the method of acquiring the coordinate value from the electrode position corresponding to the operation position is not limited to the method using the conversion coefficient, and the corresponding coordinate value may be read from the table by searching the table.

  Depending on the size of the touch area of the operating body, a plurality of coordinate values are detected as the coordinate position. In this case, the operation receiving unit 240 calculates the coordinate position of the center of gravity of the touch area and touches it. The detected operation position is detected.

  The flash memory 250 holds data given to the terminal 100 or data generated by the processor 230 in a nonvolatile manner.

The RAM 252 temporarily holds data generated by the processor 230.
The graphic memory 254 stores data for displaying an image on the display device 212. In another aspect, the RAM 252 and the graphic memory 254 may be configured as a single unit.

  The ROM 256 holds firmware for operating the terminal 100, the above-described program for accepting operation input and other various programs, and data preliminarily input as setting values for causing the terminal 100 to perform operations specific to the ROM 256. Yes.

  The display driver 214 performs a drawing operation based on data stored in the graphic memory 254 on the display device 212. The display device 212 displays an image according to the operation.

  The communication circuit 260 converts the signal received by the antenna 120 and sends the converted signal to the processor 230. In another aspect, communication circuit 260 converts the signal sent from processor 230 into a signal for transmission, and sends the converted signal to antenna 120.

  The signal processing circuit 270 converts the electrical signal sent from the microphone 160 and sends the converted signal to the processor 230. When terminal 100 outputs audio, signal processing circuit 270 converts the signal sent from processor 230 into a signal for audio output, and sends the converted signal to speaker 130. The speaker 130 outputs sound based on the signal.

  Vibrator 280 oscillates with a predetermined vibration pattern based on a signal sent from processor 230.

  Note that the operation received by the processor 230 is not limited to a user operation via the touch panel 140, and includes an operation such as pressing a physical button such as the power button 150.

  FIG. 3 is a conceptual diagram of the information input device according to the present embodiment. Referring to FIG. 3, the information input device includes a display unit 210 including a touch panel 140 and a display device 212, and an operation receiving unit 240. In FIG. 3, a display control unit 290, a graphic memory 254, and a display driver 214 are shown in relation to the information input device. The graphic memory 254 stores data such as an execution result of the program or an image to be displayed by the processor 230 and data generated by the display control unit 290 based on information from the operation reception unit 240. Accordingly, the display driver 214 drives the LCD panel of the display device 212 based on the data in the graphic memory 254, so that the display unit 210 displays an image (stroke trajectory or the like) by a user operation superimposed on the image.

  In the present embodiment, the display surface of the LCD panel of the display device 212 and the entire surface (operation surface) of the touch panel 140 placed thereon have the same shape and area, but at least the surface on which the touch panel 140 can be operated. It suffices if the display area fits inside. As described above, the area that can accept the operation input of the touch panel 140 corresponds to the display area of the LCD panel, and here, the entire surface of the LCD panel is the display area. Therefore, a user operation (such as touch) for selecting an object such as various menus, icons, buttons, a keyboard, and thumbnails with a finger can be received via the touch panel 140 regardless of the display position of the image of the object. Note that the types of user operations accepted via the touch panel 140 include an operation of sliding a finger while touching the belly of the finger on the surface of the touch panel 140.

<Functional configuration>
FIG. 4 is a diagram showing a functional configuration of the processor 230 according to the embodiment of the present invention, and shows a touch panel 140, a RAM 252 and a graphic memory 254 as related peripheral portions.

  Referring to FIG. 4, the processor 230 includes an operation receiving unit 240, a finger detection unit 245 for detecting that a finger operation (touch down, touch up, etc.) has been performed from the output of the operation receiving unit 240, an information input device A mode switching unit 255 for determining whether or not to switch the operation mode, a finger position detection unit 265 for detecting the operation position of the finger, and for enlarging (zooming-in processing) or reducing (zoom-out processing) the display image. A zoom processing unit 275 for performing the image processing, and a scroll processing unit 281 for scrolling the display image. Here, for the sake of simplicity, the terminal 100 has a zoom mode for enlarging / reducing a display image and a scroll mode for scrolling the display image as operation modes of the information input device. Suppose.

  The mode switching unit 255 includes a press determination unit 251 for determining whether or not there is a press by a touch operation, and a time determination unit 257 for measuring the time of continuous pressing from the timer output of the processor 230. . The zoom processing unit 275 includes a ratio calculation unit 271 for calculating a magnification for enlargement or reduction of the display image and an origin setting unit 272 for setting the origin of the coordinate system for the enlargement / reduction image processing. In the present embodiment, the ratio or magnification is determined with 1.0 as the size of the image stored in the graphic memory 254 and currently displayed.

Each unit in FIG. 4 is realized by a program or a combination of a program and a circuit.
<Flowchart>
FIG. 5 is a process flowchart according to the embodiment of the present invention. 6, 7, and 8 exemplify display images of the display device 212.

  The program according to the flowchart of FIG. 5 is stored in advance in a storage unit such as the ROM 256, and the CPU reads the program from the ROM 256 and executes each instruction code of the read program, thereby realizing the processing.

  Here, it is assumed that the program according to the flowchart of FIG. 5 is executed when the browser is activated. The browser indicates software (program) for displaying information such as images and characters on a display for browsing. However, the browser is not limited to the browser as long as the information is displayed on the display. Here, it is assumed that an image is displayed by a browser for the sake of simplicity.

  First, when the browser is activated and the program is executed (step S1), an image is displayed on the display device 212 (see FIG. 6A). It is assumed that mode data indicating an operation mode of the information input device is initialized to a default mode, for example, a “scroll mode” when the browser is activated. The mode data is stored in a predetermined storage area of the RAM 252.

  The finger detection unit 245 determines whether or not a touchdown is performed on the touch panel 140 based on the output (coordinate data) from the operation reception unit 240 (step S3). Specifically, when it is determined that the same coordinate data is continuously output from the operation reception unit 240 for a predetermined time counted by the timer, it is determined that the touchdown is performed. Instead of the output from the operation reception unit 240, the determination may be made from the output from the touch panel 140.

  If it is not determined that the touchdown has been performed (NO in step S3), the process in step S3 is repeated. If it is determined that the touchdown has been performed (YES in step S3), the user sets the desired position of the display image. It is assumed that the finger 301 is touched down (see FIG. 6B).

  When touchdown is determined (YES in step S3), the mode switching unit 255 causes the press determination unit 251 and the time determination unit 257 to press the touched down operation position based on the outputs of the finger detection unit 245 and the touch panel 140. It is determined whether or not the pressure is equal to or higher than a predetermined threshold (threshold pressure) for a predetermined time (step S5). That is, it is determined whether or not the current value due to pressing the same position on the touch panel 140 indicates a predetermined threshold value or more for a predetermined time. The threshold value and data for a predetermined time are stored in the ROM 256 in advance.

  If it is determined that the pressing force is equal to or greater than a predetermined threshold value for a predetermined time (YES in step S5), the mode switching unit 255 rewrites the mode data in the RAM 252 to “zoom mode”, and the zoom processing after step S7. Migrate to

  On the other hand, when it is determined that the pressing force does not show a pressure equal to or higher than a predetermined threshold value for a predetermined time (NO in step S5), the mode switching unit 255 rewrites the mode data in the RAM 252 to “scroll mode”, and in step S25 Transition to scroll processing. If the mode data indicates “scroll mode”, data rewriting is not executed.

  In the scroll process, the CPU activates the scroll processing unit 281 in response to determining that the “scroll mode” is indicated by referring to the mode data in the RAM 252. The finger position detection unit 265 is based on the output (coordinate data, trajectory data) of the operation reception unit 240, and the position information (the movement direction and movement distance of the finger) of the touch operation position on the operation surface of the touch panel 140 of the touched finger 301. Is detected. The scroll processing unit 281 scrolls the display image according to the position information of the finger 301 based on the output from the finger position detection unit 265 (step S25).

  The details of the image scrolling process are well known and will not be repeated. In brief, the scroll processing unit 281 scrolls the image data to be displayed stored in the work area of the RAM 252 based on the detected position information. The processed image data is stored in the graphic memory 254 via the display control unit 290. When the display driver 214 drives the LCD panel in accordance with the image data in the graphic memory 254, the display device 212 scrolls the image (see FIG. 7A).

  In the zoom process, the specific position detection unit of the CPU detects the touched operation position as the specific position in response to determining that “zoom mode” is indicated with reference to the mode data in the RAM 252. The CPU displays the icon 300 at the specific position (see FIG. 6C), stores the coordinates of the specific position in a predetermined storage area of the RAM 252, and activates the zoom processing unit 275. The finger position detection unit 265 detects position information (movement direction and movement distance of the finger 301) of the touched finger 301 based on the output (coordinate data, trajectory data) of the operation reception unit 240. The zoom processing unit 275 enlarges / reduces the display image according to the detected position information.

  In the present embodiment, enlargement / reduction of an image is realized by, for example, affine transformation that multiplies a coordinate value by a magnification. In the affine transformation, it is preferable to enlarge or reduce the image around the origin (0, 0) of the coordinates. For example, if the enlargement process is performed centering on the vertex at the upper left corner of the rectangular image, the image can be enlarged only in the lower right direction, and the display image is displayed in the lower right direction from the operation position indicated by the icon 300. Only the image will be enlarged.

  Therefore, in this embodiment, in order to enlarge / reduce a display image (assumed to be a rectangular image) around a specific operation position indicated by the icon 300, the zoom processing unit 275 uses image data in the graphic memory 254. , Once transferred (copied) to the work area of the RAM 252. The origin setting unit 272 matches the center point of the image in the work area (the coordinates of the specific position indicated by the icon 300) with the origin (0, 0) (step S7). On the other hand, the ratio calculation unit 271 calculates the ratio from the position information of the finger 301 output from the finger position detection unit 265. The zoom processing unit 275 enlarges / reduces the image data after moving the origin of the work area by affine transformation based on the magnification indicated by the calculation ratio, and then returns the coordinate position indicated by the icon 300 from the origin to the original position. The image data is processed as described above, and the processed image data is stored in the graphic memory 254 via the display control unit 290 (steps S21 and S23).

  As a result, an image enlarged / reduced around the partial image (the partial image indicated by the icon 300) at the operation position designated by the user with the finger 301 can be displayed (see FIG. 7C).

  In the zoom mode, the operation of the finger 301 is detected. Specifically, the finger position detection unit 265 determines, based on the output of the touch panel 140, whether or not the finger 301 is separated from the touch panel 140 (touch up) based on whether or not the output is interrupted for a predetermined time (step up). S9).

  If it is determined that the finger 301 is removed from the touch panel 140 (see FIG. 7B) (YES in step S9), it is determined again whether or not it is touched (touched down) (step S11). While no touch is detected (NO in step S11), the process in step S11 is repeated.

  When a touch is detected (YES in step S11), the finger position detection unit 265 determines whether or not the icon 300 is touched based on the output of the operation reception unit 240 (step S13). Specifically, the coordinates of the operation position where the touch is detected are compared with the coordinates of the icon 300 in the predetermined storage area of the RAM 252, and based on the comparison result, it is determined whether or not the two coordinates match. When they match, it is determined that the icon 300 is touched, and when they do not match, it is determined that the icon 300 is not touched.

  When it is determined that the icon 300 is touched (see FIG. 8B) (YES in step S13), the pressing determination unit 251 determines that the pressing force is equal to or greater than a predetermined threshold based on the output of the touch panel 140. It is determined whether or not there is (step S15). If it is determined that the value is equal to or greater than the threshold value (YES in step S15), the CPU rewrites the mode data to “scroll mode” and deletes the image of the icon 300 (step S17). As a result, the zoom mode is canceled and the series of processing ends (see FIG. 8A).

  On the other hand, if it is determined that the finger 301 is not separated from the touch panel 140 (NO in step S9), or if it is not determined that the icon 300 is touched (NO in step S13), or the pressing force by the finger 301 on the touch panel 140 is If it is determined that it is not equal to or greater than the predetermined threshold (NO in step S15), the ratio calculation unit 271 calculates a ratio from the moving direction of the finger 301 (step S19).

  Specifically, the ratio calculation unit 271 detects whether the operation position of the finger 301 has moved in a direction away from the coordinate position of the icon 300 based on the position information detected by the finger position detection unit 265 (step S19). . When it is detected that the icon 300 has moved away from the icon 300 (YES in step S19), the ratio calculation unit 271 detects the movement distance of the finger 301 from the position information, and the ratio for enlargement according to a predetermined conversion formula from the detected movement distance. (≧ 1.0) is calculated, and the above-described image enlargement process (see FIG. 7C) is performed (step S23). Thereafter, the process returns to step S9. For example, according to the predetermined conversion formula, it is assumed that the longer the moving distance is, the larger the ratio for enlargement is, and the shorter is the smaller the ratio is.

  On the other hand, when it is detected that the finger 301 has not moved in the direction away from the icon 300 (NO in step S19), that is, when the finger 301 is moved toward the icon 300, the ratio calculation unit 271 calculates the finger 301 from the position information. , And a reduction ratio (0 ≦ ratio <1.0) is calculated from the detected movement distance according to a predetermined conversion formula, and the above-described image reduction processing (see FIG. 7C) is performed. (Step S21). Thereafter, the process returns to step S9. For example, according to the predetermined conversion formula, it is assumed that the longer the moving distance, the smaller the ratio for reduction, and the shorter, the larger the ratio.

  As described above, in the process of FIG. 5, the CPU detects the strength (press level) of the touch of the finger 301 on the operation surface of the touch panel 140 and executes different processes according to the detection result.

  First, the user holds the terminal 100 main body with one hand, and touches the screen with the thumb 301, for example. When the pressing force on the screen by the finger 301 is equal to or greater than a predetermined threshold (YES in step S5), the operation mode is switched to a zoom mode for enlarging / reducing the display image.

  In the zoom mode, the icon 300 is displayed at the operation position touched by the finger 301 (step S7). The user touches the finger 301 again at a position different from the icon 300 (YES in step S9, YES in step S11, NO in step S13), and moves the finger 301 toward the icon 300, that is, toward the icon 300. When the slide is moved (touch moved) (NO in step S19), the image is reduced and displayed around the icon 300 (step S21). Similarly, when the finger 301 is slid in a direction away from the icon 300 (YES in step S19), an image is enlarged and displayed centering on the icon 300 (step S23).

  Further, in the zoom mode, after the icon 300 is displayed at the operation position touched by the finger 301 (step S7), if the finger 301 is slid without moving from the touch panel 140, that is, the direction away from the icon 300. When the finger 301 is slid and moved (NO in step S9, YES in 19), the image is enlarged and displayed around the icon 300 (step S23).

  When the icon 300 is touched again with a pressing force equal to or greater than a predetermined threshold (YES in step S9, YES in step S11, YES in step S13, YES in step S15), the zoom mode is canceled and the operation mode is Returning to the scroll mode, the icon 300 disappears from the screen (step S17).

  In the present embodiment, when operating with the finger of one hand while holding the terminal 100 main body with one hand, the desired coordinate position of the display image on the screen is designated with the finger, and the image is centered on the coordinate position. Can be enlarged / reduced.

<Modification>
In FIG. 5, after the process of step S25, the process may return to step S5. Thereby, when it is desired to enlarge / reduce the image after scrolling, it is possible to switch to the zoom mode.

  The icon 300 represents a predetermined thumbtack pattern, but the pattern is not limited to the thumbtack. The user may be able to change the pattern of the icon 300 variably.

  The display using the icon 300 is not limited as long as the center position for enlarging / reducing the image can be presented to the user. For example, the display mode of the partial image including the center position may be different from other partial images. For example, a partial image including the center position may be displayed blinking, or the color may be displayed in reverse. Further, both icon display and display mode change may be performed simultaneously.

  Regarding the switching of the operation mode, when the pressing force of the finger 301 is equal to or greater than a predetermined threshold value, switching to the zoom mode (step S5) or canceling the zoom mode (step S15) is executed. In steps S5 and S15, The thresholds used may be the same or different.

  The reference value for switching the operation mode is a pressing force, but is not limited to the pressing force. For example, switching to or canceling the zoom mode may be determined based on the length of time of continuous pressing, or based on the magnitude of the pressing force and the length of time of continuous pressing.

  The displayed information is not limited to images, and may be characters. Even in this case, enlargement / reduction and scrolling can be performed in the same manner.
