The present invention relates to the scrolling of a screen of a portable information terminal, such as a mobile telephone, etc.
With portable information communication terminals such as mobile telephones of the related art, information, etc. acquired via the Internet is displayed on a screen. When the amount of information that a user wants to display is substantial, there are situations in which it is only possible to display part of this information on a screen. It is then possible to display all of the information that the user wants to display by carrying out a so-called scrolling. �Scrolling� refers to, for example, moving an information display range up and down by one line by pressing a numeric key pad, etc. of a mobile telephone. By scrolling, it is possible for a user of a mobile telephone etc. to look through information that he wants to view in such a manner that the information is contained within the screen display range.
However, as the information display range is moved up or down one line at a time, it is necessary to perform repeatedly the same operation (for example, continually pressing the same key a number of times) in order to ensure that the information the user wants to view is contained in the display range. This is more prominent when the volume of information is large.
If the information display range is made to go up or down by one page at a time, the scrolling speed increases, and the number of operations required to ensure that the information the user wants to view is contained within the display range is reduced. However, if the portions of information displayed are moved one page at a time, then there are cases where the portions of displayed information change too drastically. As a result, there are cases where the information that the user wants to view does not appear at a position within the display range that is easy to view.
Therefore, the present invention solves the problem of including properly, with a reduced number of operations, information that the user wants to view within a display range of a screen such as that of a portable telephone and the like.
A portable information terminal of the present invention is characterized by: display means for displaying information; scrolling operation means for enabling an operator to carry out a first operation and a second operation differing from the first operation, first scrolling control means for controlling the display means to scroll through information displayed at the display means at a first speed when the first operation is carried out by the scrolling operation means; and first scrolling control means for controlling the display means to scroll through information displayed at the display means at a second speed slower than the first speed when the second operation is carried out by the scrolling operation means.
According to this configuration, it is possible to perform scrolling of information displayed by the display means selectively at different speeds in a straightforward manner using common scrolling operation means.

The following is a description with reference to the drawings of preferred embodiments of the present invention.
FIG. 1 is a view showing the external appearance of an example configuration for a mobile phone device 1 to which the present invention is applied.
A substantially disc-shaped rotating input unit 14 is provided at substantially the center of a mobile phone device 1. The rotating input unit 14 is configured so as to be capable of rotating freely in a clockwise direction and a counterclockwise direction centered about an axis of rotation that is vertical with respect to the page and substantially at the center of the page, as shown by hollow arrows. A user is able to input various instructions by operating the rotating input unit 14, a talk button 15 and power button 16 provided to the left and right respectively of the rotating input unit 14, and a numeric key pad 17 provided below.
With the mobile phone device 1 shown in FIG. 1, a user can, for example, scroll Japanese news, etc. displayed as a result of downloading from the internet by rotating the rotating input unit 14 or pressing a prescribed position of the upper surface (plane) of the rotating input unit 14 in a direction towards the inside of the mobile phone device 1 while viewing a display unit 13 included of an LCD (Liquid Crystal Display), etc.
A speaker 12 and a microphone 18 are provided respectively in the vicinity of an upper end and a lower end of the front surface of the mobile phone device 1, and these are utilized when a user talks. An antenna 11 is provided at an upper end surface of the mobile phone device 1 so as to project from the box.
The mobile phone device 1 does not have to be the so-called straight type shown in FIG. 1, and it also may be of a configuration where a first case where the display unit 13 is provided and a second case where the rotating input unit 14 and the numeric key pad 17 are provided fold via a hinge.
FIG. 2 to FIG. 5 show example structures for the rotating input unit 14.
As shown in FIG. 2, the rotating input unit 14 fundamentally includes a base 31, a holder 32, a scale 33, a dial body 34, an operating dial 35, and a central button member 36.
The base 31 is formed, for example, from an insulating resin, and it is in the shape of a substantially rectangular plate. A central button 41 is provided at the center of the upper surface of the base 31, with surrounding buttons 42A to 42D being arranged at equal intervals about the periphery. The base 31 is such that a line connecting surrounding button 42A and surrounding button 42C is substantially parallel with a central line in a direction from the top to the bottom of the mobile phone device 1 of FIG. 1. Surrounding button 42A is positioned at an upper side of the mobile phone device 1 shown in FIG. 1 and surrounding button 42B is positioned on the left side. Further, surrounding button 42C is positioned on a lower side of the mobile phone device 1 shown in FIG. 1, and surrounding button 42D is positioned on the right side (in the following, as appropriate, surrounding button 42A, surrounding button 42B, surrounding button 42C, and surrounding button 42D are referred to as upper button 42A, left button 42B, lower button 42C, and right button 42D, respectively). A claw extending towards the center of the base 31 is provided at an upward movement restricting member 43 so that upward movement of the holder 32 is restricted by this claw. Rotational movement restricting members 44A and 44B are provided with slight spacing on either side of the upward movement restricting member 43, so that rotation of the holder 32 is restricted by the rotational movement restricting members 44A and 44B. A holder restricting part 51A is formed from the upward movement restricting member 43 and the rotational movement restricting members 44A and 44B, with similar parts (holder restricting parts 51B, 51C, 51D) being arranged at the remaining three corners of the four corners of the base 31.
The holder 32 is taken to be in the shape of an insulating disc having a hole in the middle, and it is formed with a dial support cylinder 61 for supporting the dial body 34, etc. in a freely rotating manner projecting from the periphery of the hole to the upper surface side (upper side in FIG. 2) from the center of the upper surface. An axis at the center of the hole of the dial support cylinder 61 is therefore the axis of rotation of the dial body 34, etc.
Further, brushes 62A, 62B and 62C that are resilient members that are electrically conductive are arranged at the upper surface of the holder 32. The amount of rotation of the rotating input unit 14 (operating dial 35) and the direction of rotation then can be detected by detecting changes in the state of electrical connection of the brushes 62A, 62B and 62C and a scale 33 provided on the holder 32.
Specifically, the positioning of the brushes 62A and 62B in the radial direction is such as to give the position of contact with the slits 72 of the scale 33 when the scale 33 is arranged above the holder 32. When the rotating input unit 14 is then rotated so as to cause accordingly rotation of the scale 33, there is repeated contact (positions between a slit 72 and a slit 72) and non-contact (positions of the slits 72) between the brushes 62A and 62B and the scale 33.
On the other hand, when the scale 33 is arranged above the holder 32, the brush (earth brush) 62C is arranged so as to be positioned so as to make contact usually with the scale 33, so that when the scale 33 is rotated, there is repeated conduction and non-conduction with brushes 62A and 62B via the scale 33.
As a result, the amount of rotation of the rotating input unit 14 can be calculated based on the number of pulses generated corresponding to the changes (repeated contact and non-contact of the brushes 62A and 62B and the scale 33) of the conductive state between the brushes 62A and 62B and the brush 62C.
Further, it is possible to detect the direction of rotation of the rotating input unit 14 by arranging brush 62A and brush 62B to be slightly offset in the circumferential direction. In other words, in the case of rotation of the rotating input unit 14 in an counterclockwise direction in the state in FIG. 1, rises (or falls) of pulses generated as a result of contact between the brush 62A and the scale 33 can be detected at a faster timing by just the offset portion than rises (or falls) in pulses generated as a result of contact between the brush 62B and the scale 33.
Conversely, in the case of rotation of the rotating input unit 14 in a clockwise direction, rises (or falls) in pulses generated as a result of contact between the brush 62B and the scale 33 can be detected at a faster timing than rises (or falls) of pulses generated as a result of contact between the brush 62A and the scale 33.
The direction of rotation of the rotating input unit 14 can be detected therefore based on shifts in the timing of rises (or falls) of pulses appearing in this manner.
Restricted members 63A to 63D corresponding to the holder restricting parts 51A to 51D are formed at the peripheral edge of the holder 32 so that when the holder 32 is arranged on the base 31, movement (rotation and detachment) of the restricted members 63A to 63D is restricted by the holder restricting parts 51A to 51D.
Button press-down projections 101A to 101D are provided as shown in FIG. 3 at positions on the rear surface of the holder 32 corresponding to the surrounding buttons 42A to 42D. Therefore, with the mobile phone device 1 shown in FIG. 1, when the upper side of the rotating input unit 14 is pushed down in a direction perpendicular with respect to the paper, the upper button 42A (surrounding button 42A) is pushed down by button press-down projection 101A, and when the left side of the rotating input unit 14 is pushed down, left button 42B (surrounding button 42B) is pushed down by the button press-down projection 101B. Similarly, when the lower side of the rotating input unit 14 is pushed down, the lower button 42C (surrounding button 42C) is pushed down by button press-down projection 101C, and when the right side of the rotating input unit 14 is pushed down, right button 42D (surrounding button 42D) is pushed down by the button press-down projection 101D.
Dial body support members 64A to 64D are formed spaced at prescribed distances at a peripheral edge part of the holder 32 so as to project from the upper surface side (upper side in the drawing). Claws extending towards the central side of the holder 32 are formed at upper ends of the dial body support members 64A to 64D so as to restrict the detachment of the dial body 34 using these claws.
Further, a click-sensation projection 65 is provided at the upper surface of the holder 32, so that when the rotating input unit 14 is rotated, a click sensation is generated for the user by the click sensation projection 65 and a click-sensation uneven part 83 of the dial body 34.
A hole 71 into which the dial support cylinder 61 is inserted is formed at a central part of the scale 33. As described above, a multiplicity of slits 72 are formed radially with a prescribed angle pitch in the vicinity of the peripheral edge of the scale 33 at the periphery thereof. As shown in FIG. 4, the scale 33 is fixed to the rear surface of the dial body 34 on the holder 32.
A hole 81 into which the dial support cylinder 61 is inserted is formed at the center of the dial body 34, and a transmission projection 82 is formed on the upper surface of the dial body 34. The transmission projection 82 fits into a transmission recess 92 formed at the rear surface of the operating dial 35, so that rotational force of the operating dial 35 is transmitted to the dial body 34.
Further, at the peripheral edge part of the rear surface of the dial body 34, the click-sensation uneven part 83 that is wave-shaped as shown in FIG. 4 is formed over the entire periphery and, as described above, the click sensation projection 65 fits with play into this recess.
A hole 91 into which the central button member 36 is inserted with play is formed at the center of the operating dial 35. Further, the transmission recess 92 into which the transmission projection 82 of the dial body 34 fits is formed at the rear surface of the operating dial 35. The central button member 36 is shown in FIG. 2 as a cylindrical shape, but also may be spherical. A multiplicity of channels 93 extending radially are formed on the upper surface of the operating dial 35 in order to generate an appropriate amount of friction during a rotation operation to improve operability. The channels 93 also may not be present.
From each member described above, the rotating input unit 14 shown in FIG. 5 is formed from each of the members described above, and it is incorporated in a mobile phone device 1 with the upper surface of the operating dial 35 exposed.
At the rotating input unit 14 shown in FIG. 5, a user can press the upper button 42A by pressing down the upper right (upper side in FIG. 1) of the operating dial 35. Further, the lower button 42C can be pressed by pressing down the lower left (lower side in FIG. 1) of the operating dial 35.
FIG. 6 is a hardware block diagram showing the inside of an example configuration for a mobile phone device 1 to which the present invention is applied.
A control unit 111 expands a control program stored in ROM (Read Only Memory) 117A of memory 117 into RAM (Random Access Memory) 117B, and it controls operation of the whole of the mobile phone device 1 in accordance with the expanded control program.
For example, the control unit 111 exerts control so as to start up a scrolling processing program based on an instruction from a user, and it controls a display unit 13 so as to change portions of display target information that is displayed at the display unit 13, i.e., so as to scroll through displayed information. When an input to the rotating input unit 14 is detected by a rotation detection unit 121 of an input detection unit 115 (when the rotating input unit 14 is rotated), the control unit 111 controls a DSP (Digital Signal Processor), calculates rotation amount and rotation direction, etc. of the rotating input unit 14, and scrolls through information displayed at the display unit 13. Processing of the control unit 111 for changing displayed range of the display unit 13 according to input to the rotating input unit 14 is described in the following.
A RF (Radio Frequency) unit 112 transmits and/or receives electromagnetic waves to and from a base station via an antenna 11. For example, during an audio talk mode, RF signals received by the antenna 11 are amplified and subjected to frequency conversion processing and analog/digital conversion processing, etc., and the obtained audio data is outputted to a DSP 113. Further, when audio data is provided by the DSP 113, the RF unit 112 subjects this data to prescribed processing such as digital/analog conversion processing and frequency conversion processing, etc., and an obtained audio signal is transmitted from the antenna 11.
The DSP 113 then subjects the audio data provided by the RF unit 112 to, for example, spectrum inverse diffusion processing, and the obtained data is outputted to an audio codec 114. Further, the DSP 113 subjects the audio data supplied from the audio codec 114 to spectrum diffusion processing and outputs the obtained data to the RF unit 112. Moreover, the DSP 113 carries out processing to calculate the amount of rotation and direction of rotation, etc., in order to change over the display of an image based on control by the control unit 111.
The audio codec 114 converts audio for the user collected by the microphone 18 to audio data and outputs this to the DSP 113. Further, the audio codec 114 converts audio data provided by the DSP 113 to an analog audio signal and outputs a corresponding audio signal from the speaker 12.
The brushes 62A, 62B and 62C of FIG. 2 are connected to the rotation detection unit 121 of the input detection unit 115. The rotation detection unit 121 monitors the state of contact and non-contact of the brushes 62A and 62B and the scale 33 and outputs pulses corresponding to changes in the contact state to the control unit 111.
The central button 41 and the surrounding switches 42A to 42D of FIG. 2 are connected to a push-down detection unit 122 of the input detection unit 115. When these buttons are pushed down (when the upper surface of the rotating input unit 14 is pushed down in the direction of the inside), the push-down detection unit 122 detects this, and a corresponding signal is outputted to the control unit 111.
A drive 210 is connected to the control unit 111 as necessary. A magnetic disc 211, an optical disc 212, a magneto-optical disc 213, or a semiconductor memory 214, etc. is then installed as appropriate. Computer programs (for example, programs for implementing the first scrolling control unit 111 a and the second scroll control unit 111 b) are then installed in the control unit 111 as necessary.
An input detection unit 116 then detects input from other buttons, such as the talk button 15, the power button 16, and the numeric key pad 17 provided on the mobile phone device 1 and outputs corresponding signals to the control unit 111.
FIG. 7 is a functional block view of a mobile phone device (portable information communication terminal) 1 of a first embodiment of the present invention. The mobile phone device (mobile information communication terminal) 1 is equipped with the first scrolling operation unit 14 a, a second scrolling operation unit 14 b, a first scrolling control unit 111 a, a second scrolling control unit 111 b, a display unit 13, a and memory 117.
The scroll operation unit 14 a has the scale 33, the dial body 34, the operating dial 35, and the brushes 62A, 62B and 62C.
A description is now given of the operation with respect to the first scrolling operation unit 14 a with reference to FIG. 8A. The operating dial 35 of the first scrolling operation unit 14 a is made to rotate taking the central button member 36 as an axis of rotation, i.e., it is made to rotate in the direction of the arrows shown in FIG. 8A. As described previously, the amount of rotation and the direction of rotation are detected based on contact between the scale 33 and the brushes 62A, 62B and 62C. The first scrolling control unit 111 a operates based on the amount of rotation and the direction of rotation and controls the display unit 13 so as to scroll through the displayed information.
The second scrolling control unit 14 b includes the holder 32, a dial body 34, an operating dial 35, an upper button 42A and a lower button 42C.
A description is now given of the operation with respect to the second scrolling operation unit 14 b with reference to FIG. 8B. In FIG. 8B, when the operating dial 35 of the second scrolling control unit 14 b is pushed down from the top, i.e., when the operating dial 35 is pushed down in the direction of the axis of rotation of the operating dial 35, the upper button 42A is pushed. Further, when the operating dial 35 of the second scrolling control unit 14 b is pushed down from the bottom, i.e., when the operating dial 35 is pushed down in the direction of the axis of rotation of the operating dial 35, the lower button 42C is pushed. By pushing either of the upper button 42A or the lower button 42C, the second scroll control unit 111 b operates and controls the display unit 13 in such a manner as to scroll through the displayed information.
Here, the first scrolling operation unit 14 a and the second scrolling control unit 14 b share the operating dial 35. The operating dial 35 is common to the first and second scrolling operation units 14 a and 14 b, and the operating dial 35 is said to be a common member. As described above, if the operating dial (common member) 35 is rotated, the first scrolling operation unit 14 a operates and the first scrolling control unit 111 a is operated. If the operating dial (common member) 35 is pressed down, the second scrolling operation unit 14 b operates and the second scrolling control unit 111 b is operated. The operating dial 35 is thin in the direction of the axis of rotation and is a disc-shaped member with a hole 91 opened at a central portion. Here, the concept of �disc-shaped� includes items with holes and items without holes.
The scrolling speed due to the second scrolling control unit 111 b is taken to be slower than the speed of change of the first scrolling control unit 111 a. The scrolling operation of the second scroll control unit 111 b is now described with reference to FIG. 9A to FIG. 9C.
As shown in FIG. 9A, information 117 a spanning a plurality of lines exceeds a display range 13 a of the display unit 13. As a result, part of the information 117 a is displayed at the display range 13 a. Here, when the upper button 42A is pressed, as shown in FIG. 9B, the display range 13 a moves up by one line. Further, when the lower button 42C is pressed, as shown in FIG. 9C, the display range 13 a moves down by one line. In this way, because movement (scrolling) of the display range 13 a is one line at a time, this is slower than the scrolling of the first scrolling control unit 111 a that is described later.
The scrolling operation of the first scroll control unit 111 a is now described with reference to FIG. 10A to FIG. 10C and FIG. 11A to FIG. 11D.
As shown in FIG. 10A, part of the information 117 a is displayed at the display range 13 a. Here, when the operating dial 35 is made to rotate by a prescribed amount (for example, thirty degrees) in an counterclockwise direction, as shown in FIG. 10B, the display range 13 a moves up four lines. Further, when the operating dial 35 is made to rotate by a prescribed amount (for example, thirty degrees) in a clockwise direction, as shown in FIG. 10C, the display range 13 a moves down four lines. In this way, the scrolling speed due to the scrolling control unit 111 b is four times the scrolling speed due to the second scrolling control unit 111 b because the display range 13 a moves (scrolls) four lines at a time.
Further, there also are cases where headings are assigned to the information 117 a, and scrolling utilizing the headings also can be considered. A scrolling operation of the first scroll control unit 117 a utilizing headings is now described with reference to FIG. 11A to FIG. 11D. The presence or absence of headings can be determined by the first scrolling control unit 111 a. The information 117 a may be, for example, today's news downloaded via the Internet. It is typical for headings indicating topics to be assigned to news as shown in FIG. 11A. For example, it is taken that heading 0, heading 1, heading 2, heading 3, heading 4, . . . are assigned to the information 117 a. The information 117 a includes topics and a body constituting the details. Here, when the operating dial 35 is made to rotate by a prescribed amount (for example, thirty degrees) in a clockwise direction or an counterclockwise direction, as shown in FIG. 11B, just the headings are displayed. Here, when the operating dial 35 is rotated by a prescribed amount (for example, thirty degrees) in a clockwise direction, as shown in FIG. 11C, the display range 13 a moves the headings down by one line, so that heading 2, heading 3 and heading 4 are included in the display range 13 a. Further, when the operating dial 35 is rotated by a prescribed amount (for example, thirty degrees) in an counterclockwise direction, as shown in FIG. 11D, the display range 13 a moves to one line above with respect to a line of a heading, so that heading 0, heading 1 and heading 2 are included in the display range 13 a. In this way, because movement (scrolling) of the display range 13 a is one heading line at a time, this is faster than the scrolling of the second scrolling control unit 111 b that is described later.
The display unit 13 displays information 117 a recorded in the memory 117. It is preferable to display the information when halfway has elapsed for movement of the display range 13 a at the display unit 13 when the display range 13 a is moved by a scrolling operation. For example, information 117 a is displayed when the display range moves by 0.3 lines, 0.5 lines and 0.7 lines. The memory 117 records the information 117 a. Next, a description is given of the operation of the first embodiment of the invention with reference to the flowchart of FIG. 12.
First, the input detection unit 115 determines whether or not there is an input at the rotating input unit 14 (S10). If an input is present at the rotating input unit 14 (S10, Yes), a determination is made by the rotation detection unit 121 and push-down detection unit 122 as to whether the input is a rotation or pressing down of the operating dial 35 (S20).
If input to the rotating input unit 14 is a pressing down of the operating dial 35 (S20, pressing down), then the second scrolling control unit 14 b operates. Here, if the upper button 42A is pressed (S22, up), the second scrolling control unit 14 b causes the second scrolling control unit 111 b to operate. The second scrolling control unit 111 b then causes the display range 13 a to move up one line (S24 a). Further, if the lower button 42C is pressed (S22, down), the second scrolling operation unit 14 b causes the second scrolling control unit 111 b to operate. The second scrolling control unit 111 b then causes the display range 13 a to move down one line (S24 b). Then, after the display range 13 a is made to move up (down) one line (S24 a, b), a determination as to the presence or absence of input to the rotating input unit 14 (S10) is returned to.
If input to the rotating input unit 14 is a rotation of the operating dial 35 (S20, rotation), then the first scrolling control unit 14 a operates. The first scrolling operation unit 14 a then causes the first scrolling control unit 111 a to operate. The first scrolling control unit 111 a then determines whether or not headings are assigned to the information 117 a recorded in the memory 117 (S30).
If headings are not assigned to the information 117 a (S30, NO), then the first scrolling control unit 111 a carries out the scrolling described with reference to FIG. 10A to FIG. 10C. In other words, when the operating dial 35 is rotated by a prescribed amount (for example, thirty degrees) in an counterclockwise direction (S32, CCW), the first scrolling control unit 111 a causes the display range 13 a to move up four lines (S34 a). When the operating dial 35 is rotated by a prescribed amount (for example, thirty degrees) in a clockwise direction (S32, CW), the first scrolling control unit 111 a causes the display range 13 a to move down four lines (S34 b). Then, after the display range 13 a is made to move up (down) four lines (S34 a, b), a determination as to the presence or absence of input to the rotating input unit 14 (S10) is returned to.
If headings are assigned to the information 117 a (S30, Yes), then the first scrolling control unit 111 a carries out the scrolling described with reference to FIG. 11A to FIG. 11D. In other words, when the operating dial 35 is rotated by a prescribed amount (for example, thirty degrees) in an counterclockwise direction (S42, CCW), the first scrolling control unit 111 a causes the display range 13 a to move up by one line of headings (S44 a). When the operating dial 35 is rotated by a prescribed amount (for example, thirty degrees) in a clockwise direction (S42, CW), the first scrolling control unit 111 a causes the display range 13 a to move down by one line with respect to the lines of headings (S44 b). Then, after the display range 13 a is made to move up (down) by one line with respect to the lines of headings (S44 a, b), a determination as to the presence or absence of input to the rotating input unit 14 (S10) is returned to.
When there is no input to the rotating input unit 14 (S10, No), the scrolling processing ends.
According to the first embodiment, high-speed scrolling is performed by the first scrolling control unit 111 a and low-speed scrolling is performed by the second scrolling control unit 111 b. It is possible to switch over scrolling speeds, because the first scrolling control unit 111 a is caused to operate by the first scrolling operation unit 14 a and the second scrolling control unit 111 b is caused to operate by the second scrolling control unit 14 b. As a result, it is possible to include information that a user wants to view in the display range 13 a of the display unit 13 in an appropriate manner with a fewer number of operations by appropriately switching over the scrolling speed. For example, high speed scrolling is carried out when the information it is wished to view is a long way from the display range 13 a, and low speed scrolling is carried out when the information is close.
Further, operation of either the first scrolling operation unit 14 a or the second scrolling control unit 14 b can be decided upon by operating the operating dial 35 that is a common member. Specifically, if the operating dial 35 is rotated, the first scrolling operation unit 14 a operates, and if it is pressed, the second scrolling control unit 14 b operates. As a result, when changing over the scrolling speed, it is not necessary to operate a further member differing from the member that has been operated up until this time, and therefore scrolling speed can be changed over easily.
It is also possible to change over methods of high-speed scrolling using the presence or absence of headings for the information 117 a, which is convenient during high-speed scrolling of the information 117 a with headings.
The high-speed scrolling method of the first scrolling control unit 111 a in the second embodiment is different from that of the first embodiment.
The mobile phone device (mobile information communication terminal) 1 of the second embodiment of the present invention is equipped with the first scrolling operation unit 14 a, a second scrolling operation unit 14 b, a first scrolling control unit 111 a, a second scrolling control unit 111 b, a display unit 13, a and memory 117. The configuration is similar to FIG. 7. In the following, portions that are similar to the first embodiment are given the same numerals and a description thereof is omitted.
The first scrolling operation unit 14 a, the second scrolling control unit 14 b, the second scrolling control unit 111 b, the display unit 13 and the memory 117 are similar to the first embodiment.
The first scrolling control unit 111 a changes the display range of information displayed by the display unit 13. The scrolling operation of the first scroll control unit 111 a is now described with reference to FIG. 13A to FIG. 13C.
As shown in FIG. 13A, part of the information 117 a is displayed at the display range 13 a. Here, when the operating dial 35 is made to rotate by a prescribed amount (for example, thirty degrees) in a clockwise direction or an counterclockwise direction, as shown in FIG. 13B, the amount of information in the display range 13 a is increased. For example, displaying four lines of information in the display range 13 a is made to be displaying eight lines of information. The size of the characters, etc. expressing information is reduced in order to increase the amount of information in the display range 13 a. In other words, in reality, the zooming-out shown in FIG. 13C is adopted.
Here, when the operating dial 35 is rotated by a prescribed amount (for example, thirty degrees) in a clockwise direction, the display range 13 a is moved down by, for example, five to fifteen lines, and when the operating dial 35 is rotated by a prescribed amount (for example, thirty degrees) in an counterclockwise direction, the display range 13 a is moved up by, for example, five to fifteen lines, i.e., scrolling is made quicker by the zoom-out portion.
After the first scrolling control unit 111 a operates due to instructions by the first scrolling operation unit 14 a, when there are no longer any instructions from the first scrolling operation unit 14 a (when rotation of the operating dial 35 is halted), zooming-in takes place, and the display conditions for the situation before carrying out high-speed scrolling are returned to. For example, if high-speed scrolling is started from the state shown in FIG. 13A, then the state shown in FIG. 13C is attained (zoom out). Here, when rotation of the operating dial 35 is halted, the situation shown in FIG. 13A is returned to (zooming in).
Next, a description is given of the operation of the second embodiment of the invention with reference to the flowchart of FIG. 14.
First, the input detection unit 115 determines whether or not there is an input at the rotating input unit 14 (S10). If an input is present at the rotating input unit 14 (S10, Yes), a determination is made by the rotation detection unit 121 and push-down detection unit 122 as to whether the input is a rotation or a pressing down of the operating dial 35 (S20).
If input to the rotating input unit 14 is a rotation of the operating dial 35 (S20, rotation), then the first scrolling control unit 14 a operates. The first scrolling operation unit 14 a then causes the first scrolling control unit 111 a to operate. The first scrolling control unit 111 a reduces the size of the characters, etc. expressing information in order to increase the amount of information 117 a in the display range 13 a (S50).
When the operating dial 35 is rotated by a prescribed amount (for example, thirty degrees) in an counterclockwise direction (S52, CCW), the first scrolling control unit 111 a causes the display range 13 a to move in the order of five to fifteen lines up (S54 a). When the operating dial 35 is rotated by a prescribed amount (for example, thirty degrees) in a clockwise direction (S52, CW), the first scrolling control unit 111 a causes the display range 13 a to move in the order of five to fifteen lines down (S54 b).
After the display range 13 a is moved in the order of five to fifteen lines up (down) (S34 a, b), the rotation detection unit 121 determines the presence or absence of a rotational input to the rotating input unit 14 (S56). If a rotational input is present (S56, Yes), a determination (S52) of the direction of rotation (clockwise or counterclockwise) of the operating dial 35 is returned to. If there is no rotational input (S56, No), zooming-in takes place, and the state before high-speed scrolling was carried out is returned to (S58). A determination (S10) of the presence or absence of an input to the rotating input unit 14 is then returned to.
According to the second embodiment, the same effects as for the first embodiment can be demonstrated. The headings for the information 117 a are not utilized, but high-speed scrolling is carried out using zooming-out. After high-speed scrolling has ended, zooming-in takes place, and display conditions are returned to the original conditions. Therefore, information can be made easy to see after completion of high-speed scrolling.
Further, the aforementioned embodiments can be implemented as follows. Media recorded with programs for implementing each of the above portions (for example, the first scrolling control unit 111 a, the second scrolling control unit 111 b) are read by a media reading device of a computer equipped with a CPU, a hard disc, a flash memory, and a media (floppy disc, CD-ROM, memory stick, etc.) reading device, and these programs are installed in a hard disc, a flash memory, etc. It also is possible to implement the above functions in this kind of method.
According to the present invention, it is possible to perform scrolling of information displayed by the display means selectively at different speeds in a straightforward manner using common scrolling operation means.
