Description
Technical field
The present invention relates to show the picture display device of information on the picture of computing machine etc., relate in particular to and show as the technology of Capacity Plan picture greatly such as map.
background technology
In the past, as the technology for showing the large capacity information of a picture under holding not, known have a roll mode.Rolling is the technology that is not shown in the part in picture and displaying contents is moved up and down in order to show.In the situation that utilizing rolling to read large capacity information, because rolling quantitative change is many, so pretty troublesome.And, if improve rolling speed, in rolling, can not grasp displaying contents.
As the technology for changing the contraction scale that is presented at the image on picture, the known technology that has change convergent-divergent.Call " amplification " amplifying contraction scale, call " dwindling " dwindling contraction scale.By dwindling picture disply, can demonstrate the part not being presented in picture.
Most of picture display devices in past, roll and convergent-divergent has interface separately.So for by rolling and zoom operations is found out required information from jumbo image, must repeatedly roll and the blocked operation of convergent-divergent, troublesome poeration.For example, once after picture disply is dwindled, watch reduced displaying contents on one side, retrieve the approximate location of required information on one side, then, for detailed search information, must again carry out amplifieroperation.
As the method that solves aforesaid operations trouble, in non-patent literature 1, disclose the method for rolling and convergent-divergent associates.In the document, the interface of automatically adjusting zoom level according to the speed of rolling operation is disclosed.The key concept that the document proposes is, no matter the actual translational speed in information space how, all makes the superficial velocity on picture keep certain.Solve like this problem that eyes is not caught up with due to rolling.And, in the document, such scheme is also proposed, when improving when rolling speed, in order to prevent that image from sharply dwindling, calculate zoom level with the power of input value.

Fig. 4 is the figure that represents the action of the picture display device 1 of the 1st embodiment.Picture display device 1 receives the operation information sending successively from operating rod 20, carries out picture disply control according to operation information.Below explanation receives the action of the picture display device 1 after operation information.
The direction that the picture display device 1 of present embodiment is removed down from the handgrip 22 of operating rod 20 reception expression operating rods 20 and the operation information (S10) at angle of inclination thereof.Picture display device 1 is input to picture control part 12 the operation information being received by operation information acceptance division 10, and picture control part 12 temporarily stores RAM14 (S12) into the operation information of having inputted.
If the result of judgement, in the case of the state below angle of inclination is threshold value D2 continues more than time stipulated time (being no at S16), picture control part 12 is according to inputted operation information roll (S26).In the case of that to be judged as angle of inclination be state continuance below threshold value D2 is more than the stipulated time (being yes at S16), picture control part 12 judge current convergent-divergent rate be whether maximum convergent-divergent rate (preset convergent-divergent rate) (S18).
The result of this judgement, is maximum convergent-divergent rate (being yes at S18) in the case of being judged as current convergent-divergent rate, and picture control part 12 is according to inputted operation information roll (S26).Be not maximum convergent-divergent rate (being no at S18) in the case of being judged as current convergent-divergent rate, picture control part 12 carries out amplifying picture while the processing (S20) of rolling according to inputted operation information.Then, picture display device 1 turns back to the step S10 that receives operation information from operating rod 20.
Judgement (S14) result at the angle of inclination of operating rod 20, be greater than threshold value D2 and be less than threshold value D1 (being included in the region (2) of Fig. 3) at the angle of inclination of operating rod 20, picture control part 12 carries out following processing.First, picture control part 12 judges whether to change in processing (S22) in convergent-divergent.That is to say, picture control part 12 judges whether to amplify processing (S20) or dwindles processing (S32).
The result of this judgement, be judged as in convergent-divergent change process in the situation that (be yes at S22), picture control part 12 stops convergent-divergent and changes processing (S24), according to inputted operation information roll (S26).Judge whether in convergent-divergent change process in when (S22), be judged as be not convergent-divergent change process in the situation that (being no at S22), according to inputted operation information roll (S26).Then, picture display device 1 turns back to the step S10 that receives operation information from operating rod 20.
Judgement (S14) result at the angle of inclination of operating rod 20, is greater than threshold value D1 (being included in the region (3) of Fig. 3) at the angle of inclination of operating rod 20, and picture control part 12 carries out following processing.First, picture control part 12 judge the state that is greater than threshold value D1 to the angle of inclined whether continue the stipulated time more than (S28).
The result of this judgement, be greater than more than not lasting stipulated time of state of threshold value D1 in the case of being judged as angle of inclination (being no at S28), picture control part 12 is according to inputted operation information roll (S26).Be greater than more than state continuance stipulated time of threshold value D1 in the case of being judged as angle of inclination (being yes at S28), picture control part 12 judges whether current convergent-divergent rate is minimum convergent-divergent rate (S30).
The result of this judgement, is minimum convergent-divergent rate (being yes at S30) in the case of being judged as current convergent-divergent rate, and picture control part 12 is according to inputted operation information roll (S26).Be not minimum convergent-divergent rate (being no at S30) in the case of being judged as current convergent-divergent rate, picture control part 12 carries out dwindling picture disply while the processing (S32) of rolling according to inputted operation information.Then, picture display device 1 turns back to the step S10 that receives operation information from operating rod 20.
Structure and the action of the picture display device 1 of the 1st embodiment have more than been described.
At operating rod 20 when continuous tilt exceedes threshold value D1 at the appointed time in same direction, the picture display device 1 of the 1st embodiment dwindles processing (S30), in the time that this angle of inclination is less than threshold value D1, stop dwindling processing (S24).Can change to like this convergent-divergent rate arbitrarily, and, can the convergent-divergent rate when stopping rolling.As mentioned above, only utilize the operation of removing down operating rod can be easy to change convergent-divergent rate and roll, so, easily retrieve large capacity information.As map, no matter be under the state amplifying, the state still dwindling, in the situation that information is checked in hope, the structure of present embodiment is especially convenient.
The picture display device 1 of the 1st embodiment, by making operating rod 20 at the appointed time continuously to the operation (S28) of inclined, can dwindle processing.This operation can be counted as user and have a mind to check information at a distance.That is to say, in the present embodiment, when near the information in current reading when retrieving information, can not run counter to user's meaning and change the situation of convergent-divergent rate, easily carry out information retrieval.
< the 2nd embodiment >
Fig. 5 is the figure that represents the structure of the picture display device 2 of the 2nd embodiment.The basic structure of the picture display device 2 of the 2nd embodiment is identical with the picture display device 1 of the 1st embodiment.On the picture display device 2 of the 2nd embodiment, connect touch pad (タ ッ チ パ ッ De) 30, to replace operating rod 20.In the 2nd embodiment, picture control part 12 carries out picture control according to the operation information sending from touch pad 30.The following describes the control of the picture control part 12 of the 2nd embodiment.
First,, before explanation picture control part 12, touch pad 30 is first described.Touch pad 30 is to point to retouch by use the equipment of drawing touch pad and come input message.In the present embodiment, adopt and referred to that according to letting go the pressure of touch pad detects mobile pressure sensitive touch pad 30, finger position has been detected, be transformed into input value.Touch pad 30 sends to picture display device 2 representing touch pad 30 to retouch the direction of drawing and the signal (operation information) of retouching the speed of drawing.
The picture control part 12 of the 2nd embodiment is then described.Picture control part 12 has such function, according to the operation information receiving from touch pad 30, touch pad 30 is being retouched in the direction of drawing, and picture disply is rolled with the speed corresponding with retouching the speed of drawing.
And the operation information in the past that picture control part 12 is stored according to inputted operation information and RAM14, carries out the control of convergent-divergent rate.Specifically, repeatedly retouch and draw (hereinafter referred to as input repeatedly) touch pad 30 in identical direction, picture control part 12 dwindles processing.At this moment, picture control part 12 dwindles processing by certain speed, presents the situation of carrying out smoothly convergent-divergent.And, predetermine the upper limit of dwindling, in the situation that reaching upper limit convergent-divergent rate, stop dwindling processing.
In the situation that not detecting input repeatedly, picture control part 12 amplifies processing.At this moment, picture control part 12 amplifies processing by certain speed, presents and carries out smoothly convergent-divergent.And, predetermine the lower limit of amplification, in the situation that reaching lower limit convergent-divergent rate (acquiescence), stop amplifying and process.So under the state of acquiescence, picture control part 12, as long as do not detect input repeatedly, just keeps the convergent-divergent rate of acquiescence.
At this, illustrate according to repeatedly inputting and judge whether to dwindle processing.Having while repeatedly inputting, digit speed when picture control part 12 leaves touch pad 30 according to cycle repeatedly and finger, controls and dwindles processing.Specifically, the digit speed while leaving touch pad 30 according to cycle repeatedly and finger, obtains the judgment value for judging whether to dwindle processing.Present embodiment, utilizes paper helicopter model to ask this judgment value.Below describe this judgment value in detail.
Fig. 6 is the figure for the principle of asking judgment value is described.Judgment value is equivalent to " raising force " in paper helicopter model.Picture control part 12 is the speed while leaving to finger, obtains the height when the inverse in cycle (number of occurrence of each unit interval) is rotated repeatedly, as raising force.And Fig. 6 is the figure that represents principle, also can suitably adds constant when actual while obtaining raising force, or be multiplied by constant.As can be seen from Figure 6, the repetition period is shorter, and judgment value is larger, and speed when finger leaves is faster, and judgment value is larger.On the contrary, speed when finger leaves is 0, or in situation about repeatedly not inputting, judgment value is 0.The judgment value of obtaining like this becomes with user will see the value that the meaning is at a distance corresponding.Picture control part 12, in the time that " raising force " exceedes " gravity ", the same with paper helicopter flight in the model of paper helicopter, in the time that judgment value (raising force) exceedes the threshold value (gravity) of regulation, dwindle processing; Below judgment value is the threshold value stipulating time, amplify processing.In the time forming picture display device 1, set suitable value as defined threshold.
Fig. 7 is the figure that represents the action of the picture display device of the 2nd embodiment.Picture display device 2 receives the operation information sending successively from touch pad 30, carries out picture disply control according to operation information.Below explanation receives the action of the picture display device 2 after operation information.
Picture display device 2 from touch pad 30, receive represent direction that touch pad 30 is retouched to be drawn with and the operation information (S40) of speed.Picture display device 2 is input to picture control part 12 the operation information being received by operation information acceptance division 10, and picture control part 12 is kept in RAM14 (S42) the operation information of having inputted.
The picture control part 12 of picture display device 2, according to operation information, judges whether finger contacts touch pad 30 (S44).Not detecting the situation (being no at S44) that finger has contacted touch pad 30, is to point the situation that touches touch pad.Picture control part 12 judges whether finger has left touch pad 30 (S46).In this judgement, do not detecting finger leave in the situation that (being no at S46), finger moves under intact state on touch pad 30.In the case, picture control part 12 is drawn in the direction of touch pad 30 retouching, corresponding to retouching the speed of drawing roll (S60).
Detect that whether finger leaves in the judgement of touch pad 30 (S46), in the situation that detecting finger and leaving (be yes at S46), picture control part 12 calculates the speed (S48) of pointing while leaving.Speed when finger leaves is the digit speed in the small time of pointing while leaving.Then,, calculate and retouch the cycle (S50) of drawing touch pad according to the operation information of storing in RAM14 by picture control part 12.The operation information that picture control part 12 is stored according to RAM14, in the situation that detecting repeatedly input, obtains the moment of leaving from finger and plays the mean value of the required time till moment of finger contact, as the cycle; In the situation that not detecting input repeatedly, be decided to be to " ∞ " (number of occurrence=0 of each unit interval) cycle.
Speed when picture control part 12 leaves according to finger is obtained judgment value with the cycle of retouching stroke touch pad, dwindles processing in the situation that judgment value exceedes defined threshold; In the situation that judgment value is less than defined threshold, amplify processing (S52).In the situation that repeatedly not inputting, the cycle is " ∞ ", so judgment value is 0, picture control part 12 amplifies processing.But, to press, the convergent-divergent rate of acquiescence is carried out in the situation of picture disply, no longer carries out its moral amplification processing in addition, so, keep the convergent-divergent rate of giving tacit consent to.Then, picture control part 12 turns back to the step S40 that receives operation information from touch pad 30.
In the judgement (S44) of the detection to finger contact touch pad 30, in the time detecting finger contact (being yes at S44), picture control part 12 carries out following processing.Whether speed when first, picture control part 12 judges finger contact touch pad 30 is 0 (S54).Digit speed in small time when speed when finger contact touch pad 30 is finger contact.And, in this judgement (S54), judge whether speed is 0, still, even stress speed and be not 0 from strict meaning, also can speed be judged as to 0 by picture control part 12.Within the scope of what, speed is judged as to 0, suitably sets according to the susceptibility of touch pad etc.
In this judgement (S54), if speed is judged as and is not 0 (being no at S54) in the time of finger contact, picture control part 12 is drawn in the direction of touch pad 30 according to retouching the speed of drawing roll (S60) retouching.
