(embodiment 2)
Below, with reference to Fig. 3, Fig. 4 the acoustics of embodiments of the present invention 2 being described, this acoustics has been used the video-unit of embodiment of the present invention 1, so omit the explanation of the part identical with embodiment 1.
Fig. 3 is the synoptic diagram that the touch panel of the video-unit in the automobile audio of embodiment of the present invention 2 is shown.
As shown in Figure 3, the size of supposing the input area of touch panel is 136 * 126, and promptly length (X-direction) has 136 coordinates, and width (Y-axis) direction has 126 coordinates.When the setting coordinate with the upper left corner of touch panel was (0,0), the coordinate in the lower left corner of touch panel was that the coordinate in (0,126), the upper right corner is that the coordinate in (136,0), the lower right corner is (136,126).
The input area of supposing this touch panel is to be left upper end, to be the rectangular area of bottom righthand side with coordinate (128,108) with coordinate (8,18).The input area of this rectangle is divided into 1+30+30+30 * 30=961 the effective Petting Area B 0000 of sound volume setting, corresponding one of the effective Petting Area of each sound volume setting is used for audio pattern E 0000 that the volume of four sound channels is all around controlled, the wherein numeral of " zero " expression 0～9.For convenience of explanation, suppose that the 4-digit number of the effective Petting Area B 0000 corresponding sound effect pattern E 0000 of sound volume setting is identical.
So-called " the effective Petting Area of sound volume setting " is equivalent to effective Petting Area of the touch panel in the embodiment 1, the indicate sound volume setting value of output sound, so-called " sound volume setting value " be meant the value that the volume of at least one sound channel in four sound channels of left-right and front-back is set or be meant to about or the value set of the balance of the volume of front and back sound channel.So-called " audio pattern " is equivalent to the processing project in the embodiment 1.Can certainly come to set arbitrarily their concrete implication as required.
At this, " audio pattern E 0000 " is defined as: the volume of two sound channels is differential about the front two numeral, and back two digits is represented volume differential of former and later two sound channels.For example, audio pattern E-15-15 represents give great volume 15 grade of the volume of L channel than R channel, and the volume of preceding sound channel is than give great volume 15 grades of back sound channel; Audio pattern E1400 represents that the volume of L channel is littler 14 grades than the volume of R channel, and the volume of preceding sound channel is identical with the volume of back sound channel.
Particularly, be that the center of (68,63) is set at 1 effective Petting Area B0000 of sound volume setting with coordinate, corresponding to audio pattern E0000.
In addition, will be with coordinate (8,63) be high order end, with coordinate (128,63) (remove coordinate (68 for the Left-Right line of low order end, 63)), with 4 coordinates is unit, from left to right be divided into 30 the effective Petting Area B-1500 of sound volume setting, B-1400 ..., B1400, B1500, correspond respectively to 30 kinds of audio pattern E-1500, E-1400 ..., E1400, E1500.
Equally, will be with coordinate (68,18) be topmost, with coordinate (68,108) (remove coordinate (68 for Front-Rear line bottom, 63)), with 3 coordinates is unit, be divided into from top to bottom 30 the effective Petting Area B0015 of sound volume setting, B0014 ..., B00-14, B00-15, correspond respectively to 30 kinds of audio pattern E0015, E0014 ..., E00-14, E00-15.
Moreover, with the other parts of the rectangle input area of touch panel, be unit with 4 * 3 (X-axis is 4 coordinates, and Y-axis is 3 coordinates), be divided into 900 effective Petting Areas of sound volume setting, correspond respectively to 900 kinds of audio patterns.
The effective Petting Area of [table 1] coordinate and sound volume setting, audio pattern corresponding tables
Table 1 is the effective Petting Area of coordinate and sound volume setting, audio pattern corresponding tables, be stored in the storage unit of video-unit of acoustics of present embodiment, when showing as mentioned above input area with touch panel and being divided into 961 effective Petting Areas of sound volume setting, the corresponding relation between the coordinate of touch panel and 961 effective Petting Areas of sound volume setting and 961 the audio patterns.
As shown in table 1, when coordinate is (58,93) time, the front two numeral of X coordinate effective Petting Area of 58 pairing sound volume settings and audio pattern is " 03 ", the back two digits of Y coordinate effective Petting Area of 93 pairing sound volume settings and audio pattern is-10, so coordinate (58,93) is corresponding to the effective Petting Area B-03-10 of sound volume setting, audio pattern E-03-10, the volume of expression L channel is than give great volume 3 grades of R channel, and the volume of preceding sound channel is than give great volume 10 grades of back sound channel.
Fig. 4 shows the synoptic diagram of picture displayed on the display unit of the video-unit in the automobile audio of embodiment of the present invention 2.
As shown in Figure 4, in the picture on being presented at display unit, show " a volume control band " that is surrounded by double solid line, this " volume control band " is corresponding with 961 effective Petting Areas of sound volume setting of touch panel in fact, represents 961 kinds of audio patterns.When the user wanted to change the volume of the music listened to etc., the prompting according to the literal of picture shown in Figure 4, lines etc. realized by the relevant position that touches in " volume control band ".
But, in present embodiment 2, the minimum effective Petting Area B0000 of sound volume setting is the size of a coordinate only, the maximum effective Petting Area of sound volume setting has only the size of 4 * 3=12 coordinate only, therefore the position of all audio patterns of prompting in can not the picture on being presented at display unit, even pointed out the position of all audio patterns, for the user, the audio pattern of selecting to want to obtain with the effective Petting Area of the corresponding sound volume setting of finger touch also is very difficult exactly.
Then, when illustrating that with reference to the process flow diagram of Fig. 2 the user touches the touch panel of video-unit of acoustics of embodiment of the present invention 2, the action of acoustics.
Suppose that touch panel touched for the first time the first time contact coordinate be (68,63), corresponding to the effective Petting Area B0000 of sound volume setting, audio pattern E0000.
At this moment, if the touch panel that calculates at step S2 is touched for the second time second time, the coordinate of contact was (74,59), then at step S3, by the effective Petting Area audio of coordinate shown in 1 and the sound volume setting pattern corresponding tables of tabling look-up, contact (74,59) are positioned at the effective Petting Area B0202 of sound volume setting for the second time as can be known, so judge that this contact for effectively, enters step S4 second time.
At step S4, calculate as current contact the second time contact coordinate (74,59) with as last time the contact the first time contact coordinate (68,63) between coordinate poor.The difference of X coordinate is 74-68=6, and the difference of Y coordinate is 59-63=-4.
At this, suppose that the lower limit of regulation of the difference of X coordinate is 0, the set upper limit value is 16; The lower limit of the regulation of the regulation of the difference of Y coordinate is 0, and the set upper limit value is 18.So, because poor-4 the absolute value 4 of the absolute value 6 of the difference 6 of X coordinate, Y coordinate all in the scope between set upper limit system and lower limit, so enter step S8.
In step S8,, from 961 effective Petting Areas of sound volume setting, select an effective Petting Area of sound volume setting and be defined as current volume and set effective Petting Area B Xdumy according to the coordinate and the variable quantity of the coordinate of contact for the first time of the contact second time

In addition, because x
2=50,51,85,86 o'clock, for the first time the X coordinate of contact and for the second time the absolute value of the difference of the X coordinate of contact more than or equal to set upper limit value 16, so, the pairing effective Petting Area of these coordinates is defined as current effective Petting Area by tabling look-up 1.
Table 3 show when the Y coordinate of contact for the first time be 63 and when the Y coordinate of contact is respectively 45～62,64～81 for the second time, according to the first time contact the Y coordinate and the expression determined of the variable quantity of the Y coordinate of contact for the second time before and after the current volume of volume of sound channel set effective Petting Area.
According to table 3 as can be known, work as y

Then, the user touches touch panel for the third time.
At this moment, if at the coordinate of the contact for the third time that step S2 calculates during for (76,56), at step S3, by tabling look-up 1, as can be known this for the third time contact (76,56) be positioned at the effective Petting Area B0203 of sound volume setting, so judge this for the third time the contact for effectively.
At step S4, calculate as the coordinate (76,56) of the contact for the third time of current contact with as last time the contact the second time contact coordinate (74,59) between coordinate poor.The difference of X coordinate is 76-74=2, and the difference of Y coordinate is 56-59=-3.
At this, because poor-3 the absolute value 3 of the absolute value 2 of the difference 2 of X coordinate, Y coordinate is all in the scope between set upper limit system and lower limit, so enter step S8.
In step S8, as mentioned above,, from 961 effective Petting Areas of sound volume setting, select an effective Petting Area of sound volume setting and be defined as current volume and set effective Petting Area B Xdumy according to the coordinate of contact for the third time and the variable quantity of the coordinate of contact for the second time

。As mentioned above, in step S8, coordinate (74 according to the contact second time, 59) coordinate (76 of contact and for the third time, 56) variable quantity, determine that for the third time it is B0303 that the current volume of contact is set effective Petting Area, rather than be stored in the effective Petting Area B0203 of the pairing sound volume setting of coordinate (76,56) of the contact for the third time that the table 1 in the storer 105 puts down in writing.
As mentioned above, though when touching for the second time, enlarge the effective Petting Area X01 of sound volume setting by the effective Petting Area X02 of interim sacrifice sound volume setting temporarily, enlarge the effective Petting Area Y01 of sound volume setting by the effective Petting Area Y02 of interim sacrifice sound volume setting, Y03 temporarily, but when touching for the third time, equally can be by the interim effective Petting Area of other sound volume setting of sacrificing, the effective Petting Area of sound volume setting of being sacrificed before selecting.So, since each all according to the effective Petting Area of the pairing sound volume setting of contact coordinate last time and last time contact coordinate and the variable quantity of current contact coordinate determine that the current volume of current contact sets effective Petting Area, the error of bringing so can not make the effective Petting Area of some sound volume setting of interim sacrifice is accumulated one by one.
Certainly, the invention is not restricted to this embodiment 2, also can in aim of the present invention, change.For example, also can be set under some particular case, for example under the situation about in official hour, touch panel being touched for the third time, not according to step S8, and according to step S7, the coordinate of contact was irrelevant with last time, and the effective Petting Area of the pairing sound volume setting of current contact directly is defined as the effective Petting Area of sound volume setting.
Moreover, though present embodiment 2 has illustrated the situation of substitution formula 1 in step S8, but formula 1 is one gives an example, the invention is not restricted to this, can carry out various changes as the case may be, as long as can realize coming the position and/or the size of a part of effective Petting Area of Iterim Change according to the variable quantity of the coordinate of adjacent twice contact.

In brief, the acoustics of embodiment of the present invention 3, in the step S8 of Fig. 2, at first according to the coordinate of the current current contact of being touched and touched last time last time the contact the variable quantity of coordinate calculate the interim coordinate of current contact, will be stored in the current volume that the effective Petting Area of the pairing sound volume setting of this interim coordinate in the storage unit is defined as current contact then and set effective Petting Area.
Then, when illustrating that with reference to the process flow diagram of Fig. 2 the user touches the touch panel of video-unit of acoustics of embodiment of the present invention 3, the action of acoustics.
Suppose that touch panel touched for the first time the first time contact coordinate be (38,90), corresponding to the effective Petting Area B-08-09 of sound volume setting, audio pattern E-08-09.
At this moment, if the touch panel that calculates at step S2 is touched for the second time second time, the coordinate of contact was (45,79), then at step S3, by the effective Petting Area audio of coordinate shown in 1 and the sound volume setting pattern corresponding tables of tabling look-up, contact (45,79) are positioned at the effective Petting Area B-06-06 of sound volume setting for the second time as can be known, so judge that this contact for effectively, enters step S4 second time.
At step S4, calculate as current contact the second time contact coordinate (45,79) with as last time the contact the first time contact coordinate (38,90) between coordinate poor.The difference of X coordinate is 45-38=7, and the difference of Y coordinate is 79-90=-11.
At this, suppose that the lower limit of regulation of the difference of X coordinate is 0, the set upper limit value is 16; The lower limit of the regulation of the regulation of the difference of Y coordinate is 0, and the set upper limit value is 18.So, because poor-11 the absolute value 11 of the absolute value 7 of the difference 7 of X coordinate, Y coordinate all in the scope between set upper limit system and lower limit, so enter step S8.
In step S8,, calculate the interim coordinate (x of current contact according to formula 2 according to the coordinate and the variable quantity of the coordinate of contact for the first time of the contact second time

Certainly, the invention is not restricted to this embodiment 3, also can in aim of the present invention, change.For example, when also can be in official hour touch panel being touched for the third time, not according to step S8, and according to step S7, the coordinate of contact was irrelevant with last time, and the effective Petting Area of the pairing sound volume setting of current contact directly is defined as the effective Petting Area of sound volume setting.
Moreover, the formula that calculates interim coordinate time substitution in step S8 also is not limited to formula 2, can carry out various changes as the case may be, as long as can realize size or position that interim coordinate that the variable quantity according to the coordinate of adjacent twice contact calculates can the partly effective Petting Area of Iterim Change.
(embodiment 4)
Below, with reference to accompanying drawing 5,6 explanation embodiments of the present invention 4, the key distinction of the video-unit 100 of itself and embodiment of the present invention 1 is, is not poor according to the coordinate of adjacent twice contact, but determines current effective Petting Area according to priority.
Fig. 5 shows the block diagram of the video-unit 200 of embodiment of the present invention 4.As shown in Figure 5, the video-unit 200 of embodiment of the present invention 4 comprises display unit 201, touch panel 202, touch panel detecting unit 203, computing unit 204, storer 205 and control module 207.Because display unit 101, touch panel 102, the touch panel detecting unit 103 of display unit 201, touch panel 202, touch panel detecting unit 203 and Fig. 1 are basic identical, so omit explanation to them.
Computing unit 204 is used to carry out various calculating.For example, when touch panel 202 is touched, according to parameters such as touch panel detecting unit 203 detected voltages, calculate the touch panel 202 current current contact of being touched coordinate (X, Y).
Storage unit 205 is used for storing various information.For example, can store in advance the input area of touch panel 202 has been divided a plurality of effective Petting Area priority separately that forms.
Control module 207 is used for each unit of video-unit 200 is controlled.For example, when touch panel 202 is touched, among a plurality of effective Petting Area that is had in the specialized range of the position of being touched, select the high effective Petting Area of priority to be defined as current effective Petting Area, and carry out processing project corresponding to this current effective Petting Area.
In addition, the setting of the priority of relevant each effective Petting Area promptly can manually be imported by input medias such as keyboard, mouses from the outside by the user, also can be by on-vehicle navigation apparatus or its video-unit automatic setting.For example, the video-unit in the on-vehicle navigation apparatus of the present invention also possesses the unshowned priority level initializing of figure unit, and this priority level initializing unit touches the priority that frequency is set each effective Petting Area according to the quilt of each position of touch panel.
Then, when illustrating that with reference to Fig. 6 the user touches the touch panel 202 of video-unit 200 of embodiment of the present invention 4, the action of video-unit 200.
Fig. 6 is the process flow diagram of work that the video-unit 200 of embodiment of the present invention 4 is shown.
As shown in Figure 6, at first, at regular intervals, whether the voltage by touch panel detecting unit 203 senses touch panels 202 is 0V (volt) (step S11).When voltage is 0V, (be "Yes" among the step S11), be judged as touch panel 202 not to be touched repeated execution of steps S11.When voltage is not 0V, (be "No" among the step S11), will output to computing unit 204 by touch panel detecting unit 203 detected magnitudes of voltage.
Computing unit 204 calculates the two-dimensional coordinate of the touch face 202 current current contact of being touched according to the voltage of input, calculate simultaneously a plurality of effectively Petting Areas are arranged in the specialized range of current contact, give variable N with the number assignment of effective Petting Area, wherein N is positive integer (step S12).Simultaneously, this N stores in the storage unit 205.
Then, judge whether N is " 0 " (step S13).If N is not 0 (being "No" among the step S13), then transfer to step S14.
Then, one of the N that will determine in step S12 effective Petting Area that effectively the Petting Area medium priority is the highest is defined as current effective Petting Area, and makes N successively decrease 1, i.e. N=N-1 (step 14).
Then, judge whether touch panel 202 is touched (step S15) once more in official hour.When in official hour, being touched once more, (be not "No" among the step S15), then transfer to step S18, carry out the pairing processing project of current effective Petting Area that is determined at last.
When in official hour, being touched once more, (be "Yes" among the step S15), then, judge whether this is touched once more is (the step S16) that is touched in the mode of predesignating.Wherein, so-called " mode of predesignating " can be imported from the outside as required by the user and set, also can be by video-unit 200 according to the preset rule automatic setting." mode of predesignating " for example can be to touch touch panel once more through after the stipulated time, or in the position of the contact of being touched once more apart from the distance of the position of the contact of being touched last time value for regulation, or the same position of touch panel is by sustained touch more than the stipulated time.
When be (being "Yes") when being touched in the mode of predesignating in step S16, then irrelevant with the priority of effective Petting Area, according to the coordinate of current contact, according to embodiment of the present invention 1～3, perhaps prior art is determined current effective Petting Area.When not being (being "No" in step S16) when being touched in the mode of predesignating, turn back to step S13, one of remaining N effective Petting Area that effectively the Petting Area medium priority is the highest of non-selected mistake is defined as current effective Petting Area.
In step S13, if N is 0 (being "Yes" among the step S13), then transfer to step S18, carry out after last current effective Petting Area of determining, return step S12.
More than, the structure and the workflow thereof of the video-unit 200 of embodiment of the present invention 4 have been described with reference to Fig. 5 and Fig. 6.But the structure of video-unit of the present invention is not limited thereto, can be as embodiment 2, on the basis of the process flow diagram of the video-unit 200 of Fig. 5 and Fig. 6, carry out various changes as required.
For example, in this video-unit 200 of Fig. 5, be provided with display unit 201, touch panel 202, touch panel detecting unit 203, computing unit 204, storer 205 and control module 207 respectively separately, but also can be and become a unit with plurality of units modularization wherein, also can increase and decrease assembly of elements as required.
For example, in the process flow diagram of Fig. 6, in step S13, be judged as N=0 or in step S15, be judged as when not touched once more at the appointed time, just transfer to step S18, carry out the pairing processing project of current effective Petting Area, but obviously also can after each definite current effective Petting Area, just carry out its pairing processing project at once.
For example, in the process flow diagram of Fig. 6, in step S16, the user can end to determine according to the height of priority the operation of current effective Petting Area by the mode of predesignating, can when being touched for the first time, come to determine current effective Petting Area according to the priority but manifest also, and which time (for example for the second time) when quilt is touched just not according to priority but alternate manner is determined current effective Petting Area.
(embodiment 5)
Below, with reference to Fig. 7 the guider of embodiments of the present invention 5 being described, this guider has used the video-unit of embodiment of the present invention 4, so omit the explanation of the part identical with embodiment 4.
Fig. 7 shows the synoptic diagram of picture displayed on the display unit of the video-unit in the guider of embodiment of the present invention 5.As shown in Figure 7, the picture that is presented on the display unit is a map, shows four zones of A, B, C, D that surrounded by heavy line on this map, represents dining room, bank, hospital, school respectively, and its priority is respectively 1,2,3,4.At this, suppose the priority that more little numeral is high more.And, suppose that " mode of predesignating " touched more than the stipulated time continuously for touch panel.
When the user touches the position a shown in Figure 7 of touch panel, the coordinate of this time contact that the computing unit 204 of the video-unit in the on-vehicle navigation apparatus calculates.Suppose coordinate according to this time contact, calculate in the scope (can set arbitrarily as required) of regulation 4 effective Petting Area A, B, C, D are arranged, then set N=4, and 4 effective Petting Area A, B, C, effective Petting Area A that the D medium priority is the highest are defined as current effective Petting Area.
Then, when the user in official hour once more (promptly for the second time) when touching the position in this position a or this position a specialized range, the highest effective Petting Area B of priority among 3 effective Petting Area B except that effective Petting Area A, C, the D among 4 effective Petting Area A, B, C, the D is defined as current effective Petting Area.
