  Hereinafter, the case where the touch panel device and the image display method according to the embodiment of the present invention are applied to a multifunction device having a so-called touch panel function will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 is a functional block diagram showing a main configuration of a multifunction machine 100 according to the first embodiment of the present invention. The multi-function device 100 includes a control unit 10, an image input unit 20, an image processing unit 30, an image output unit 40, a transmission / reception unit 50, an operation panel 60, and a storage unit 70.

The image input unit 20 includes a light source that irradiates light to a reading document, an image sensor such as a CCD (Charge Coupled Device), and the like, and optically reads image data of the document. Further, the image input unit 20 forms a reflected light image from the original placed at a predetermined reading position on the image sensor, and generates RGB (R: Red, G: Green, B: Blue) analog data. Output.

  For example, the image processing unit 30 generates digital image data based on the analog data input from the image input unit 20, or reads out the image data stored in the storage unit 70, and sets each image type. After performing the corresponding processing, image data to be output (printed) is generated. The output image data generated by the image processing unit 30 is output to the image output unit 40.

  The image output unit 40 prints an image based on the image data output from the image processing unit 30 on a recording medium such as recording paper or an OHP film. The image output unit 40 generates a electrostatic latent image on the photosensitive drum by emitting a laser beam in accordance with image data received from outside, a photosensitive drum, a charger for charging the photosensitive drum to a predetermined potential, and externally received image data. A laser writing device, a developing device for supplying toner to the electrostatic latent image formed on the surface of the photosensitive drum for development, a transfer device for transferring the toner image formed on the surface of the photosensitive drum onto a recording medium, etc. For example, an image is output onto a recording medium by electrophotography.

  The transmission / reception unit 50 includes a network card, a modem, and the like for transmitting the document data to the outside.

  Further, the operation panel 60 is a function button for switching functions such as “fax”, “copy”, “print”, “mail”, etc. in the multi-function device 100, a numeric keypad, a start key, a cancel key, and a command for confirming the received instruction. It has an enter key. The operation panel 60 includes a touch panel unit 61, a pressure sensor unit 62 (detection means), and a display unit 63.

The touch panel unit 61 includes a touch panel (not shown), and the touch panel (contacted surface) is provided so as to cover the display screen of the display unit 63. For example, the touch panel unit 61 is a multi-touch resistive film type. In the multi-touch resistive touch panel, a spacer (5 to 10 μm) is sandwiched on a glass surface serving as a base, and a film (PET sheet having a thickness of about 200 μm) is attached to the surface. Transparent electrode grids made of ITO are provided on the mutually facing surfaces. The resistive touch panel is configured to detect a contacted position by measuring a partial pressure ratio due to the resistance of the transparent electrode on each of the glass surface and the film surface.

  Therefore, the touch panel unit 61 can accept designation of a predetermined position on the display screen of the display unit 63 by a touch operation of the touch panel by the user. The touch panel unit 61 detects the coordinates on the display screen of the display unit 63 corresponding to the contact position, and generates a signal for specifying the coordinates. The touch panel unit 61 is not limited to this, and may be configured to use a pointing device (for example, a stylus pen).

The display unit 63 includes, for example, an LCD or an EL (Electroluminescence) panel,
An image to be output (printed) on a predetermined recording sheet is displayed via the image output unit 40. The display unit 63 displays information to be notified to the user, such as the status of the multifunction peripheral 100, the status of job processing, the image of the document read by the image input unit 20, and the operation details of the operation panel 60. To do. The display screen of the display unit 63 is covered with the touch panel unit 61.

  The pressure sensor unit 62 is interposed between the touch panel unit 61 and the display unit 63. The pressure sensor unit 62 detects the pressure applied to the touch panel unit 61. The pressure sensor unit 62 can detect the pressure applied to the touch panel unit 61 (touch panel) in the entire range of the touch panel. The pressure sensor unit 62 detects the pressure applied to the touch panel, and outputs a pressure value corresponding to the magnitude of the pressure as an electric signal. Such an electrical signal output from the pressure sensor unit 62 is sent to the control unit 10. For example, the pressure sensor unit 62 uses a known piezoresistive sensor.

  The storage unit 70 is configured by, for example, a non-volatile storage medium such as flash memory, EEPROM (registered trademark), HDD, MRAM (magnetoresistance memory), FeRAM (ferroelectric memory), or OUM.

  The storage unit 70 also stores a pressure value threshold table. In the pressure value threshold value table, a plurality of pressure value threshold values are associated with a scroll display speed to be described later.

  FIG. 2 is a functional block diagram showing a main configuration of the control unit 10 in the multifunction machine 100 according to the first embodiment of the present invention. The control unit 10 includes a CPU 11, a ROM 12, a RAM 13, a display control unit 14, a direction determination unit 15, and a speed determination unit 16.

  The ROM 12 stores in advance fundamentally fixed data among various control programs and calculation parameters, and the RAM 13 temporarily stores the data and reads it regardless of the storage order, storage position, etc. Is possible. The RAM 13 stores, for example, a program read from the ROM 12, various data generated by executing the program, parameters that change as appropriate during the execution, and the like.

  The CPU 11 loads the control program stored in advance in the ROM 12 onto the RAM 13 and executes it, thereby controlling the various hardware described above and operating the entire apparatus as the multifunction peripheral 100 of the present invention. Further, the CPU 11 receives an instruction for predetermined processing from the user via the touch panel unit 61.

  The display control unit 14 controls image display on the display unit 63. For example, the image displayed on the display unit 63 is scroll-displayed in the direction determined by the direction determination unit 15 at the speed determined by the speed determination unit 16.

  The direction determining unit 15 determines the direction related to the scroll display of the image displayed on the display unit 63. More specifically, when the touch panel unit 61 receives designation of a plurality of positions by a user's contact operation, the direction determination unit 15 determines the scroll display direction based on the positions related to the designation of the plurality of positions.

  For example, in the case of a so-called drag operation in which the position of contact changes while the user's fingertip is in contact with the touch panel, the pressure sensor unit 62 performs detection a plurality of times during the drag. More specifically, during such a drag, the pressure sensor unit 62 performs detection at a detection timing at regular or non-periodic intervals, and the direction determination unit 15 determines a direction based on a position related to any two timings. To do. That is, the direction determining unit 15 determines a direction connecting the positions related to any two timings in a straight line as the scroll display direction.

  Further, when the user's fingertip contacts the touch panel a plurality of times at a predetermined interval, the direction is determined based on a position related to any two of the plurality of contacts. For example, a direction that connects a position related to the first contact and a position related to any one of the second and subsequent contacts in a straight line is determined as the scroll display direction.

  The speed determination unit 16 determines the scroll display speed based on the detection result of the pressure sensor unit 62. That is, the speed determination unit 16 increases or decreases the scroll display speed according to the magnitude of the pressure value detected by the pressure sensor unit 62. For example, the speed determination unit 16 determines the corresponding speed by comparing the pressure value detected by the pressure sensor unit 62 with the threshold table for the pressure value.

  In the multi-function device 100 according to the first embodiment of the present invention having the above-described configuration, the direction and speed of the image scroll display on the display unit 63 can be easily adjusted in accordance with the user's touch operation. .

  FIG. 3 is a flowchart for explaining processing for adjusting the direction and speed of scroll display in the multi-function device 100 according to the first embodiment of the present invention. For convenience of explanation, a case where the user performs a so-called drag operation and scrolls the image displayed on the display unit 63 will be described as an example. During the drag, the pressure sensor unit 62 performs detection at a regular detection timing, and the direction determination unit 15 determines the direction of the scroll display based on the position related to the first contact and the position related to the first timing. Shall be determined. The RAM 13 stores the timing at which pressure is detected by the pressure sensor unit 62.

  For example, when the user touches the display screen (touch panel) of the display unit 63 with a fingertip, the touch panel unit 61 detects the touched position and sends a signal specifying the coordinates of the position to the CPU 11.

  Based on the signal from the touch panel unit 61, the CPU 11 determines whether or not there is a touch (touch) on the touch panel (step S101). When the CPU 11 determines that there is no contact with the touch panel (step S101: NO), the CPU 11 repeatedly performs such determination.

  Further, when the CPU 11 determines that there is a touch on the touch panel (step S101: YES), the CPU 11 detects the position (coordinates) on the display screen of the display unit 63 related to the touch based on the signal from the touch panel unit 61. (Step S102).

  At this time, the CPU 11 assigns 1 to “N” and stores it in the RAM 13 (step S103).

  The CPU 11 determines whether or not it is time to detect the pressure by the pressure sensor unit 62 based on the time measurement result of the time measuring unit (not shown) and the detection timing of the RAM 13 (step S104).

  When the CPU 11 determines that it is not the time when the pressure sensor 62 should detect the pressure (step S104: NO), the CPU 11 repeatedly performs such determination.

  On the other hand, if the CPU 11 determines that it is time to detect the pressure by the pressure sensor unit 62 (step S104: YES), “N + 1” is newly substituted as “N” and stored in the RAM 13 (step S105). ). That is, “2” is stored in the RAM 13 as the value of “N”. In other words, the first contact in step S101 is treated as the first detection timing in the subsequent processing.

  Next, the CPU 11 refers to the stored contents of the RAM 13 and determines whether “N” is “2” (step S106). If the CPU 11 determines that “N” is not “2” (step S106: NO), that is, if it is the timing of the third and subsequent detections, the process proceeds to step S108.

  On the other hand, since it is the timing of the second detection at present, “N” is “2”, and the CPU 11 determines that “N” is “2” (YES in step S106). At this time, the direction determining unit 15 determines the direction related to the scroll display of the image based on the position of the contact detected at the timing of the first detection and the second detection (step S107). That is, during the drag, the direction determining unit 15 determines a direction connecting the positions related to the first and second detection timings as a straight line as the scroll display direction.

  Next, the pressure sensor unit 62 detects the pressure value applied to the touch panel by contact according to the timing of the second detection (step S108). Further, the speed determination unit 16 determines the corresponding speed by comparing the pressure value detected by the pressure sensor unit 62 with the threshold table of the pressure value as the speed of scroll display of the image (step S109).

  Further, the display control unit 14 scrolls and displays the image displayed on the display unit 63 in the direction determined by the direction determination unit 15 at the speed determined by the speed determination unit 16 (step S110).

  Next, the CPU 11 determines whether or not the touch to the touch panel has been released based on the signal from the touch panel unit 61 (step S111).

  If the CPU 11 determines that the touch on the touch panel has not been removed (step S111: NO), that is, if the drag operation is continuously performed, the process returns to step S104.

Thereafter, the processing from step S108 to step S110 is repeated until the user's drag operation is completed. In other words, as illustrated in FIG. 4, during the user's drag operation, the speed at which the images displayed on the sequential display unit 63 are scroll-displayed is changed according to the change in the pressure with which the fingertip presses the touch panel. .

  On the other hand, if the CPU 11 determines that the touch on the touch panel has been removed (step S111: YES), the process ends.

  As described above, in MFP 100 according to the first embodiment of the present invention, the direction and speed in scroll display of such an image are determined only by the user's operation of pressing the fingertip against the touch panel, thereby improving operability. be able to. Further, the user can change the scroll display speed of the image each time only by appropriately adjusting the pressure (pressure).

(Embodiment 2)
FIG. 5 is a flowchart for explaining processing for adjusting the direction and speed of scroll display in the multi-function device 100 according to the second embodiment of the present invention. For convenience of explanation, a case where the user performs a so-called drag operation and scrolls the image displayed on the display unit 63 will be described as an example. During the drag, the pressure sensor unit 62 performs detection at a regular detection timing, and the direction determination unit 15 determines the direction of the scroll display based on the position related to the first contact and the position related to the first timing. Shall be determined. The RAM 13 stores the timing at which pressure is detected by the pressure sensor unit 62.

  For example, when the user touches the display screen (touch panel) of the display unit 63 with a fingertip, the touch panel unit 61 detects the touched position and sends a signal specifying the coordinates of the position to the CPU 11.

  Based on the signal from the touch panel unit 61, the CPU 11 determines whether or not there is a touch (touch) on the touch panel (step S201). When the CPU 11 determines that there is no contact with the touch panel (step S201: NO), the CPU 11 repeatedly performs such determination.

  If the CPU 11 determines that the touch panel has been touched (step S201: YES), the CPU 11 detects the position (coordinates) on the display screen of the display unit 63 related to the touch based on the signal from the touch panel unit 61. (Step S202).

  At this time, the pressure sensor unit 62 detects the pressure value applied to the touch panel by such contact and stores it in the RAM 13 (step S203).

  Thereafter, the processing from step S204 to step S209 is the same as the processing from step S103 to step S108 in FIG. 3, and detailed description thereof will be omitted.

  In step S208, when the pressure sensor unit 62 detects the pressure value applied to the touch panel by contact according to the timing of the second detection, the speed determination unit 16 detects the pressure value (hereinafter referred to as the pressure value detected by the pressure sensor unit 62). , Referred to as a detected pressure value), a weight value is added to the speed of the pressure value threshold table corresponding to the detected pressure value to determine the scroll display speed of the image (step S210).

  That is, the speed determination unit 16 determines a predetermined weight value according to the detected pressure value, and adds the determined weight value to the speed according to the threshold table of the pressure value corresponding to the detected pressure value, This is determined as the scroll display speed of the image.

  Henceforth, the process in step S211 and step S212 is the same as the process in step S110 and step S111 of FIG. 3, and detailed description is abbreviate | omitted.

  As described above, in the multifunction machine 100 according to the second embodiment of the present invention, the speed of the subsequent scroll display of the image is changed according to the pressure value at the time of the first touch (contact) during the drag operation by the user. Add weight to the decision.

  FIG. 6 is a graph showing the relationship between the detected pressure and the scroll display of the image in the multifunction machine 100 according to the second embodiment of the present invention. In FIG. 6, the drag operation displayed with a thick solid line, a dotted line, and a solid line has the same initial pressure value, but the subsequent pressure values are the same.

  That is, in the multifunction machine 100 according to the second embodiment of the present invention, the speed in the scroll display of the image varies depending on the pressure value at the time of the first contact even if the subsequent detected pressure values are the same.

  As a result, in the MFP 100 according to the second embodiment of the present invention, it is possible to reach the image scroll display speed desired by the user more quickly.

(Embodiment 3)
In the above description, the case where the user performs a drag operation has been described as an example. However, the multifunction peripheral 100 according to the present invention is not limited to this, and the user performs a plurality of touches (contacts) at predetermined intervals. It is configured so that it can cope with the case.

  FIG. 7 is a flowchart for explaining processing for adjusting the direction and speed of scroll display in the multifunction machine 100 according to the third embodiment of the present invention. For convenience of explanation, a case where the user performs a drag operation together with the second touch operation at a predetermined time interval after the first touch operation will be described as an example. In addition, the direction determination unit 15 determines the scroll display direction based on the positions related to the first and second touch operations.

  Furthermore, the multi function device 100 according to the third embodiment of the present invention includes a counting unit (not shown) that counts the number of times of touch (contact) by the user. For example, when the user touches the display screen (touch panel) of the display unit 63 with a fingertip, the touch panel unit 61 detects the touched position, sends a signal specifying the coordinates of the position to the CPU 11, and the counting unit Counts the number of contacts.

  Based on the signal from the touch panel unit 61, the CPU 11 determines whether or not there is a touch (touch) on the touch panel (step S301). When the CPU 11 determines that there is no contact with the touch panel (step S301: NO), the CPU 11 repeatedly performs such determination.

  If the CPU 11 determines that there is a touch on the touch panel (step S301: YES), the CPU 11 determines whether the contact is the first contact based on the count result of the counting unit (step S301). S302).

  When the CPU 11 determines that the contact is the first contact (step S302: YES), the CPU 11 detects the position (coordinates) on the display screen of the display unit 63 related to the contact based on the signal from the touch panel unit 61. (Step S309). Thereafter, the process returns to step S301.

  When the CPU 11 determines that the contact is not the first contact (step S302: NO), that is, in the present embodiment, when the contact is the second contact, the direction determination unit 15 performs the first and second times. Based on the contact position, the direction related to the scroll display of the image is determined (step S303). That is, the direction determining unit 15 determines a direction connecting the positions related to the first contact and the second contact as a straight line as the scroll display direction.

  Next, the pressure sensor unit 62 detects the pressure value applied to the touch panel by the first contact (step S304). Further, the speed determination unit 16 determines the corresponding speed by comparing the pressure value detected by the pressure sensor unit 62 with the threshold table of the pressure value as the scroll display speed of the image (step S305).

  At this time, the display control unit 14 scrolls and displays the image displayed on the display unit 63 in the direction determined by the direction determination unit 15 at the speed determined by the speed determination unit 16 (step S306).

  As described above, in this embodiment, since the user performs a drag operation at the second touch (contact), the CPU 11 determines whether or not it is time to detect the pressure by the pressure sensor unit 62. (Step S307). On the other hand, the RAM 13 stores the timing at which pressure is detected by the pressure sensor unit 62.

  If the CPU 11 determines that it is time to perform pressure detection by the pressure sensor unit 62 (step S307: YES), the process returns to step S304.

  On the other hand, if the CPU 11 determines that it is not time to detect the pressure by the pressure sensor unit 62 (step S307: NO), the CPU 11 determines whether or not the touch to the touch panel has been released based on the signal from the touch panel unit 61 ( Step S308).

  If the CPU 11 determines that the touch on the touch panel has not been removed (step S308: NO), that is, if the drag operation is continuously performed, the process returns to step S307.

  Thereafter, the processing from step S304 to step S306 is repeated until the user's drag operation is completed. Therefore, as shown in FIG. 8, during the user's drag operation, the speed at which the images displayed on the display unit 63 are scroll-displayed is changed according to the change in the pressure with which the fingertip presses the touch panel.

  On the other hand, if the CPU 11 determines that contact with the touch panel has been removed (step S308: YES), the CPU 11 ends the process.

  As described above, the MFP 100 according to the third embodiment of the present invention can cope with a case where the user performs a plurality of touches (contacts) at a predetermined interval.

(Embodiment 4)
The multi-function device 100 according to the fourth embodiment of the present invention is also configured to cope with a case where the user performs a plurality of touches (contacts) at predetermined intervals.

FIG. 9 is a flowchart for explaining processing for adjusting the direction and speed of scroll display in the multifunction machine 100 according to the fourth embodiment of the present invention. For convenience of explanation, a case where the user performs a plurality of touch operations at predetermined time intervals will be described as an example. In addition, the direction determination unit 15 determines the scroll display direction based on the positions related to the first and second touch operations. Furthermore, the multi function device 100 according to the fourth embodiment of the present invention includes the counting unit (not shown) and a time measuring unit (not shown) that measures the time elapsed from the start of contact.
It has.

  For example, when the user touches the display screen (touch panel) of the display unit 63 with a fingertip, the touch panel unit 61 detects the touched position and sends a signal specifying the coordinates of the position to the CPU 11. In addition, the counting unit counts the number of times of contact, and the timing unit starts timing.

  Based on the signal from the touch panel unit 61, the CPU 11 determines whether or not there is a touch (touch) on the touch panel (step S401). When the CPU 11 determines that there is no contact with the touch panel (step S401: NO), the CPU 11 repeatedly performs such determination.

  Further, when the CPU 11 determines that the touch panel has been touched (step S401: YES), the CPU 11 determines whether or not the operation related to the touch has continued for a predetermined time or more based on the time measurement result of the time measuring unit. . That is, the CPU 11 determines whether or not the operation related to the contact is a long press (step S402).

  When the CPU 11 determines that the operation related to the contact is a long press (step S402: YES), the process is terminated.

  On the other hand, when the CPU 11 determines that the operation related to the contact is not a long press (step S402: NO), the CPU 11 determines whether or not the contact is the first contact based on the count result of the counting unit ( Step S403).

  When the CPU 11 determines that the contact is the first contact (step S403: YES), the CPU 11 detects the position (coordinates) on the display screen of the display unit 63 related to the contact based on the signal from the touch panel unit 61. (Step S410).

  At this time, the pressure sensor unit 62 detects the pressure value applied to the touch panel by such contact and stores it in the RAM 13 (step S411). Thereafter, the process returns to step S401.

  On the other hand, when determining that the contact is not the first contact (step S403: NO), the CPU 11 determines again whether or not the contact is the third or more contact based on the count result of the counting unit (step S403). S404).

  If the CPU 11 determines that the contact is the third or more contact (step S404: YES), the process proceeds to step S406.

  Further, when the CPU 11 determines that the contact is not the third contact or more (step S404: NO), that is, when the contact is the second contact, the direction determining unit 15 determines the position of the first contact and the second contact. Based on this, the direction related to the scroll display of the image is determined (step S405).

  Next, the pressure sensor unit 62 detects the pressure value applied to the touch panel by the second or third contact (step S406). Further, the speed determination unit 16 adds a weight value to the speed according to the threshold table of the pressure value corresponding to the detected pressure value detected by the pressure sensor unit 62 and determines the speed as the scroll display speed of the image (step). S407).

  That is, the speed determination unit 16 determines a predetermined weight value according to the detected pressure value related to the first contact, and sets the weight value determined to the speed related to the threshold table of the pressure value corresponding to the detected pressure value. Is added to determine the scroll display speed of the image.

  At this time, the display control unit 14 scrolls and displays the image displayed on the display unit 63 in the direction determined by the direction determination unit 15 at the speed determined by the speed determination unit 16 (step S408).

  Next, the CPU 11 determines whether contact with the touch panel has been removed based on a signal from the touch panel unit 61 (step S409).

  CPU11 returns a process to step S408, when it determines with the contact with the said touch panel not having come off (step S409: NO).

  On the other hand, if the CPU 11 determines that the touch on the touch panel has been removed (step S409: YES), the process returns to step S401.

  As described above, in the MFP 100 according to the fourth embodiment of the present invention, when the user performs a plurality of touches (contacts) at a predetermined interval, the fingertip presses the touch panel every time such a contact is made. As shown in FIG. 10, the speed at which the images displayed on the sequential display unit 63 are scroll-displayed is changed according to the pressure change.

  Further, in the multifunction machine 100 according to the fourth embodiment of the present invention, a weight value is added to the determination of the speed in the subsequent scroll display of the image according to the pressure value at the time of the first touch (contact). Therefore, as shown in FIG. 10, the speed in the scroll display of the image differs depending on the pressure value at the time of the first contact even if the detected pressure value related to the subsequent touch operation is the same.

  As a result, in the multifunction peripheral 100 according to the fourth embodiment of the present invention, it is possible to quickly reach the scroll display speed desired by the user.
