Abstract

When communicating data, the transmitter reads a plurality of sets of gradation data related to a same subject and transmits the plurality of sets of gradation data. The receiver decides an optimal number of shades for output purposes, receives the transmitted data and, by analyzing the number of shades in each received set of gradation data, determines which of the received sets of gradation data has the optimal number of shades. The receiver then extracts the received set of gradation data with the optimal number of shades and performs output.

Description

The reception transmitting apparatus of a plurality of data that the tonal gradation number is different and reception sending method

Technical field

The invention relates to by transmission character font data such as communication line and broadcaster and pictorial data and for receiving and showing Data Receiving dispensing device that data adopted and the Data Receiving sending method that this is sent out.

Background technology

Data Receiving is sent out in the system, sometimes the gradation data of the data of font of Fa Songing and image etc. for being made of a plurality of tonal gradations.Under the situation that sends such gradation data, the ability etc. that institute can gray-scale displayed progression be received the transcriber of device side limits, the gradation data that can not be sent out by the number of greyscale levels demonstration of its former state at receiver side.Such situation is that the gray-scale data that receiving system will be received be transformed to data that receiver side can gray-scale displayed progression and shows etc. again in the past.

Utilize description of drawings reception always to send the operation of the system of gray-scale data below.At first, Fig. 1 shows the functional-block diagram that receives transmitting system.This transmission and reception apparatus is such as shown, constitute by data sending device 100 and data sink 200, data sending device 100 has data-reading unit 101, sends with data output unit 102 and data transmission unit 103, and data sink 200 has Data Receiving unit 201, gradation data converter unit 202, optimum gradation determining unit 203 and gradation data output unit 204.

Fig. 2 is the flow chart that shows the operation of system.Abide by this figure below its operation is described.

(S11) at first, the gradation data A that sends in the data-reading unit 101 of transmitter side reading of data dispensing device 100.As an example, suppose that what read is 4 grades of gray-scale datas of Figure 10 at this.

(S12) secondly, the transmission data of the form that the gradation data A dateout transmitting element 103 that is read with data output unit 102 by transmission can send.

(S13) then, data transmission unit 103 will send to receiving system 200 as sending the gradation data A that generates with data.

(S14) receive the gradation data A that sends by data sending device 100 with Data Receiving unit 201 at receiver side.

(S15) then, optimum gradation determining unit 203 is that the state of transcriber etc. is determined the treatable optimum gradation progression of receiver side in view of the object output of gradation data output unit 204.Here for example suppose that receiver side can treatable number of greyscale levels be confirmed as 2 grades of gray scales.

(S16) thus, gradation data converter unit 202 transforms to the number of greyscale levels that optimum gradation determining unit 203 is determined with the gradation data A that receives.Here, be that to transform to optimum gradation determining unit 203 determined number of greyscale levels be 2 gradation data for 4 gradation data with the number of greyscale levels that receives.And when the number of greyscale levels of the gradation data that is received is above, be not carry out conversion in optimum gradation determining unit 203 determined number of greyscale levels.

Transform to the method for the gradation data of 2 grades of gray scales as gradation data with 4 grades of gray scales, for example take the pixel with gray value " 0 " and " 1 " of the gradation data before the conversion is not added conversion as in statu quo gray value, the pixel with gray value " 2 " and " 3 " then is transformed to the method for " 1 ".As the conversion carrying out, the reception data of 4 grades of gray scales shown in Figure 10 promptly are transformed to the gradation data of 2 grades of such as shown in Figure 3 gray scales.

(S17) last, gradation data output unit 204 will be transformed into the treatable optimum gradation progression of receiver side, be that the reception data of 2 grades of gray scales output to transcriber here.Just can surpass the reproduction etc. of transmission data of the number of greyscale levels of disposal ability at receiver side by above operation.

But by above-mentioned such when operating in receiver side and handling the gradation data that is sent by transmitter side, the quality that occurs reproduced data is the situation of deterioration significantly.That is, transforming at 4 grades of gradation datas under the situation of 2 grades of gradation datas of Fig. 3 above-mentioned Figure 10,2 grades of gradation datas of Fig. 3 close links the part that should not correlate, and grade worsens.Though can be read because of font is single in this example, in the situation of the character font data of complicated shape, will occur being difficult to read the situation that character can't be done to differentiate completely because of conversion.

This is not only merely owing to reduce because of number of greyscale levels reduces the grade taken place, also comprises the reason that makes that this undesirable shape part of transmitter side manifests significantly etc. owing to transform method.On the other hand, also might improve the grade that to differentiate character even reduce number of greyscale levels as carrying out appropriate demonstration corresponding to the level that can show with this number of greyscale levels.This is not only like this to font data, in pictorial data too.

In above-mentioned reception sending method, for example only send in the situation of 2 grades of gradation datas at transmitter side, also have only and utilize 2 grades of gradation datas although receiver side has the ability of the data of utilizing 8 grades of gray scales, thereby can not utilize the function of receiver side fully neatly.

And if take method as described above, the part that must have the tonal gradation number of conversion gradation data in the receiving system, and in not having the receiving system of converting means, can't all reproduce the gradation data of reception, also can become unserviceable grade even reproduce.

Summary of the invention

Purpose of the present invention solves above-mentioned such problem with regard to being, provides to make the apparatus and method of reproducing gradation data etc. rightly that can not damage the grade of original data according to the ability of receiver side.

Above-mentioned purpose realizes as following.At first, read the different a plurality of gradation datas of tonal gradation number of relevant same target at transmitter side, send read a plurality of gradation datas.On the other hand, at receiver side, with the number of greyscale levels of treatable the best of object output of receiver side as optimum gradation progression, number of greyscale levels to the gradation data that receives is analyzed, retrieve from the gradation data that receives according to this analysis result and to determine behind the gradation data with aforementioned optimum gradation progression to extract this extraction gradation data that is determined and gradation data is outputed to aforementioned object output as extracting gradation data.

Here " same object " is not same on form, and is meant on the meaning of information identical.For example, at as the font data of " ぁ ", corresponding to the difference of the level that can express each gray scale, in each number of greyscale levels, also comprise variation as the character form of " ぁ " and line thick line etc.And the gradation data that sends in reading can read transmission singly, also can be concentrated.

Above-mentioned when doing like this, a plurality of gradation datas that the number of greyscale levels of relevant same target is different are sent out, owing to can be exported by the gradation data that wherein extracts corresponding to the number of greyscale levels of the best of the ability of object output at receiver side, so can effectively utilize the ability of the object output of receiver side, and can prevent the reduction of the grade of data.

Under the above-mentioned state, as a plurality of gradation datas of each same object being concentrated into one group at receiver side, when at receiver side when selecting a gradation data at a plurality of gradation datas of same target, alternative is clear and definite, and can realize the simplification and rapidization of processing.

As being concentrated into such one group method, can be to concentrate, perhaps by the additional link information of the gradation data of relevant same target is concentrated by the gradation data that connects relevant same target.So-called " connection " is meant data made physically arrangement mutually with adjoining.And when connecting, preferably carry out according to the order of certain benchmark relevant with the number of greyscale levels of each gradation data.

As concentrating by the above-mentioned gradation data that connects in this wise, receiver side receives a plurality of gradation datas of concentrating like this, can select a gradation data by a relevant object ground in these a plurality of data that physically connect, with further rapidization that realizes handling.When connecting, carry out, utilize this benchmark just can easier and promptly extract gradation data at receiver side as order according to certain benchmark of the number of greyscale levels of relevant each gradation data.

In addition, as gradation data being concentrated into one group by gradation data is added link information, even a plurality of gradation datas disperses, can easily specify the alternative of with an an object relevant gradation data with link information as clue at receiver side, also need not stipulate the sending order of each gradation data and can improve the flexibility of handling at transmitter side.

Preferably also to send out the attribute information of the relevant gradation data that sends simultaneously at transmitter side.Just may select to have gradation data in by a plurality of gradation datas at receiver side thus according to attribute information corresponding to the number of greyscale levels of the best of disposal ability etc.

This attribute information is preferably in additional separately corresponding attribute information on the gradation data of transmission, and is sent as table information in conjunction with attribute information.

When the gradation data adeditive attribute information of inciting somebody to action so separately, when analyzing each gradation data, receiver side just can analyze easily according to the attribute information that is added.

And when transmission is combined with the table information of attribute information, then can be by by table information gathering and carry out the analysis of gradation data when receiver side is analyzed gradation data, thus can analyze fast.If send table information in advance, just can select the gradation data that should receive, the gradation data portion of closing that will then not send to be write down in advance and only select necessary gradation data at receiver side, thereby can reduce the required memory capacity of receiver side.

In addition, sending simultaneously as aforementioned same target and the textual data that reads as each character that also will constitute corresponding textual data when reading textual data at transmitter side, then is extremely useful.Here so-called " textual data " be meant the character group and show the data of its arrangement, can also not be the alphabet that constitutes textual data as each character of aforementioned same target.

Like this, receiver side can constitute the putting in order of each character of text according to the identification of the textual data sent out, and unlikely misidentification is represented the information of text, selects the optimal gradation data to each character that constitutes text, and can carry out the processing of appropriate demonstration etc.

The processing of above-mentioned such transmitter side also can be carried out when sending simultaneously, and the data that also can make transmission usefulness as described above in addition adopt independent dispensing device that it is sent as sending with data output.So-called work " is exported with data as sending " and is meant and will process object makes the treatable data mode output of dispensing device, this data mode changes with the ability of dispensing device process data, for example in dispensing device data conversion is generated as the data that are adapted to corresponding conversion for the situation that sends usefulness also comprises.

On the other hand, under situation about also sending except that aforementioned a plurality of gradation data by transmitter side, preferably analyze the number of greyscale levels of the gradation data of reception at receiver side according to corresponding attribute information about the attribute information of the number of greyscale levels of each gradation data.Can improve the efficient of analysis whereby and realize handling high speed.

At receiver side, when when aforesaid a plurality of gradation datas add aforementioned attribute information respectively separately, according to attribute information additional on each gradation data that receives, if analyze the number of greyscale levels of the gradation data that is received, analytic attribute information on the gradation data of analyzing then just can be simpler and easy, promptly analyze.

Be combined with in formation under the situation of table information of aforementioned attribute information, aforementioned gradation data analytical equipment is as the number of greyscale levels according to this table gradation data that information analysis received, because the number of greyscale levels according to a plurality of gradation data of this table information gathering is analyzed, thereby can more effectively analyze.

In addition, aforementioned a plurality of gradation data with situation about being connected according to order about certain benchmark of the number of greyscale levels of each gradation data under, when receiver side is clue extraction gradation data with corresponding benchmark, because this benchmark is based on gradation data, so can more easily carry out the extraction of gradation data.

At receiver side, when not having the gradation data of number of greyscale levels in the gradation data that receives, in the gradation data that receives, the gradation data with the number of greyscale levels that is no more than aforementioned optimum gradation progression can be determined as extracting gradation data with aforementioned the best.Can obtain the gradation data of the treatable number of greyscale levels of object output in view of the above reliably with receiver side.And in this case, dependence will be no more than the gradation data of the maximum number of greyscale levels of having of aforementioned optimum gradation progression to be determined as a pinch gradation data, can obtain the gradation data of number of greyscale levels of the best of relevant object output in the situation of the gradation data that does not have optimum gradation progression.

On the other hand, at receiver side, when not having gradation data in the gradation data that receives, determine to extract the number of greyscale levels that gradation data also can be transformed to this corresponding extraction gradation data aforementioned the best according to certain benchmark with aforementioned optimum gradation progression.Also can under the situation of the gradation data that does not have optimum gradation progression, divide the disposal ability of waving object output fully in view of the above.

This moment as employing have the number of greyscale levels benchmark of the minimum that surpasses aforementioned optimum gradation progression as aforesaid certain benchmark, even under the situation of the gradation data that does not have optimum gradation progression, also can make give full play to the disposal ability of object output in, the reduction of the data grade that the ground inhibition of possible limit causes because of conversion.

And aforementioned same target for each character of constituting textual data, situation that this textual data also is sent out in, receiver side can be exported the gradation data of relevant character according to textual data.Just might correctly reproduce the text that is sent at receiver side in view of the above.

These and other purpose, advantage and characteristic of the present invention is by being expressly understood below in conjunction with the accompanying drawing illustration of describing particular of the present invention.Listed accompanying drawing is:

Have the operation of carrying out each parts that the following describes in each comfortable general computer of the gradation data dispensing device 1 of said structure and gradation data receiving system 2, dress is realized with the program of these computer action in can also relying on.And this program can be recorded in the recording medium of the floppy disk that can be read separately by aforementioned computer etc.

Though be also can utilize the wire communication device of telephone line etc. with wireless reception and the transmission of carrying out data here.For hardware configuration described above also is same in the following embodiments.

The following describes the functional imperative that the gradation data that relates to embodiment 1 receives transmitting system.The gradation data of the expression embodiment of the invention 1 receives the functional-block diagram of transmitting system among Fig. 5.Here transmission and reception apparatus is represented as gradation data dispensing device 1A, gradation data receiving system 2A separately.

Gradation data dispensing device 1A is obtained unit 12, attribute information extra cell 13, same target data combining unit 14, is sent and constitute with data output unit 15 and data transmission unit 16 by gradation data reading unit 11, attribute information, and the part of removing data transmission unit 16 forms transmission grey data generating device 1a.

Gradation data reading unit 11 is read about the different a plurality of gradation datas of the number of greyscale levels of same target by storing apparatus 56.Here, suppose as what send data it is to send character font data, and read a plurality of gradation datas about pre-prepd same character code, font character wide, font height.But, the data of transmission as be gradation data what kind of all can, also can be pictorial data etc.

Attribute information is obtained unit 12 and is obtained attribute information about each gradation data of obtaining.Here, obtaining of attribute information be, is about to it and extracts and be used if having information about gray scale in the gradation data itself, if not then analyze gradation data and generate and obtain about the attribute information of gradation data.Here as attribute information except that gray scale, also to obtain the size of wide and the high and gradation data of character code, font.

13 pairs of attribute information extra cells read the additional corresponding respectively attribute information of gradation data.Specifically, attribute information is obtained the attribute information obtained unit 12 data here as structure such shown in Fig. 6, with its be attached to read the starting of each gradation data as heading message.And when attribute information needn't be as the heading message of gradation data, also can append to other assigned position.The structure of data of attribute information if can be discerned gradation data and also can not take structure as described above, and this is self-evident.

It is one group part that same target data combining unit 14 is concentrated each same target for a plurality of gradation datas that will read, and connects according to the benchmark that be linked in sequence of relevant each gradation data from the big beginning of number of greyscale levels at this gradation data that will add attribute information.Be used for the desirable various schemes of benchmark of this connection, can connect, also can connect according to order corresponding to the frequency of utilization of number of greyscale levels by the order of the little beginning of number of greyscale levels.Though be concentrated into one group at this to connect, also can concentrate by additional link information on each gradation data.Wide, the high three of font of character code, font in the attribute information of can adopting same as before as link information.Much less, also special string can be appended on each gradation data as link information.

Send with data output unit 15 to the connected gradation data that attribute information is arranged that adds is made the part that can be sent out with data by the transmission that data transmission unit 16 sends such form.When connected gradation data can in statu quo be sent by data transmission unit 16, send with data output unit 15 and promptly export gradation data same as before through connection.

Data transmission unit 16 is to send the transmission that generates with the grey data generating device 1a part of gradation data to receiving system 2A transmission, and transmission control device 55 is suitable with it.

On the other hand, gradation data receiving system 2A is made of Data Receiving unit 21, data record unit 22, gradation data output unit 23, gradation data analytic unit 24a, optimum gradation determining unit 25, extraction gradation data determining unit 26 and gradation data extraction unit 27.

Data Receiving unit 21 is for being received the part about the different a plurality of gradation datas of the grey of the same target that is sent out by gradation data dispensing device 1A, data record unit 22 is the part of this gradation data that receives of record, and gradation data output unit 23 is to object output output gray level section data.Though be to use display unit 68 as object output as described above at this, object output also can be that printer etc. changes any form of handling with gray scale.

Gradation data analytic unit 24a is the part of the number of greyscale levels of the gradation data of analysis reception, is the number of greyscale levels of analyzing gradation data on each gradation data according to the attribute information shown in the Fig. 6 that is added as heading message by attribute information extra cell 13 here.But can understand in advance, this moment is at receiver side, though each gradation data so can full out know maximum number of greyscale levels, just can more promptly carry out the analysis of gradation data by by being linked in sequence of the big beginning of gradation data in view of the above.

This gradation data analytic unit 24a also generates analysis result storage table such shown in Fig. 7 according to the analysis result of the attribute information of Fig. 6.This analysis result storage table is classified by each same character code, font is wide, font is high character, with the data address in the number of greyscale levels of the index of record gradation data number, optimum gradation data, each gradation data, size of data, the data record unit 22.Data address is deposited the initial address in the data record unit 22 of gradation data separately.The index of suitable gradation data " " hurdle writes down the address of the extraction gradation data that extraction gradation data determining unit 26 described later determines.The structure of analysis result storage table is not limited to the above, for example, also can be at first by the character code classification, then wide by font again, height is made disaggregated classification.

Optimum gradation determining unit 25 is with the object output of aforementioned gradation data output unit 23, be defined as optimum gradation progression for the number of greyscale levels of display unit 68 treatable the bests here.For example, optimum gradation progression is confirmed as 8 grades of gray scales when the display unit 68 of object output only can be handled maximum 8 grades of gray scales.This optimum gradation progression depends on the gray scale disposal ability of object output, has under a plurality of situations receiving the other side, with separately situation and different.Though normally determine optimum gradation progression by the gray scale disposal ability of object output, in object output the situation of his purposes of tool when using several color in addition etc., also may there be the situation that changes optimum gradation progression according to this number of colors that is used.Though be only to determine optimum gradation progression here by the disposal ability of object output, in addition also can be with reference to above-mentioned analysis result table.In doing such processing, the most suitable number of greyscale levels is increased, change optimum gradation progression according to the difference of character.

Extract gradation data determining unit 26 and extract gradation data by gradation data and definite conduct that retrieval in the gradation data that receives has the aforementioned optimum gradation progression that is determined according to aforementioned gradation data analytic unit 24a income analysis result.But when in the gradation data that receives, not having gray scale, the gradation data that has the number of greyscale levels that is no more than this optimum gradation progression in the gradation data that receives is determined as extracting gradation data with determined optimum gradation progression.

Gradation data extraction unit 27 is for extracting by the part of extracting gradation data determining unit 26 determined extraction gradation datas.Be specifically, address with reference to record in the storage of decomposition result shown in Fig. 7 table by extraction gradation data determining unit 26 determined gradation datas, extract corresponding gradation data by data record unit 22, it is sent to gradation data output unit 23 according to the output request.

The following describes the operation that the gradation data with said structure receives transmitting system.At first according to the operation of the flowchart text transmitter side of the operation that shows gradation data dispensing device 1A shown in Fig. 8.

This be supposition about with " pressures " this character as sending object, transmission has the wide and high three kinds of gradation datas as Fig. 9,10,11 2,4,8 grades of such gray scales shown in separately of same font.They adopt the character font data corresponding to the appropriate shape of the level that can be shown by each number of greyscale levels separately.These gradation datas are to have in 1 pixel by 0 bit map data to the gray value of (number of greyscale levels-1), for example as have in 1 pixel when being the gradation data of 8 grades of gray scales by 0 to 7 value.Though be minimum gradation value to be distributed to white, maximum gradation value distribute to gray values black, in the middle of their and be assigned to grey in this example, it made other colors also do not have anti-as toning in the middle of the white and black.Prepare a plurality of gradation datas in advance at transmitter side, they are recorded in the storing apparatus 56 with different like this number of greyscale levels.

(S101) read the such gradation data group X of a plurality of gradation datas shown in Fig. 9～11 at transmitter side by gradation data reading unit 11.

(S102) gradation data of each that then obtain that the 12 pairs of aforementioned gradation data reading units 11 in unit read at attribute information is obtained the attribute information of gradation data.At this, except that promptly 2,4,8, also obtaining size of data " 32 " " 64 " " 96 " according to character code " OX3035 ", font wide " 16 ", font height " 16 " and the gradation data separately of the Japanese Industrial Standards of " pressure " as the number of greyscale levels of separately gradation data.

(S103) 13 pairs of attribute information extra cells read the additional corresponding separately attribute information of gradation data.Here, as described above attribute information is made heading message such shown in Fig. 6, with the title of its additional gradation data as separately.Gradation data shown in Fig. 9～11 is indicated in Figure 12 (a) and (b) (c) by additional heading message separately.

(S104) same target data combining unit 14 connects the additional gradation data separately that attribute information is arranged then.At this, connect each gradation data with sequence arrangement as described above by the big beginning of gray scale.What produced here is that first connects 8 grades of gradation datas, and second connects 4 grades of gradation datas, and the 3rd connects 2 grades of gradation datas.One example of the data that this result is generated is shown among Figure 13 (a) as conceptual diagram.And as shown in Figure 13 (b), common information in the attribute information, here wide, the font of character code, font high as in conjunction with the title division of gray scale degree certificate in common information carry out record, can be number of greyscale levels and size of data at this also at the only additional intrinsic attribute information of each gradation data.

(S105, S106) sends with data output unit 15 and will make through the gradation data that connects and can be exported to data transmission unit 16 with data by the transmission of the such form of data transmission unit 16 transmissions, and the data transmission unit 16 that receives it sends to gradation data receiving system 2A with this gradation data.

Subsequently, according to the operation of the flowchart text receiver side of the operation that shows the gradation data receiving system 2A shown in Figure 14.

(S201, S202) receives shown in the Figure 13 (a) that is sent out the gradation data of structure like that in receiver side Data Receiving unit 21.The data that this is received record in data record unit 22 then.

(S203) gradation data analytic unit 24a analyzes the attribute information that is added on the gradation data that receives.Gradation data analytic unit 24a makes the analysis result storage table of such form shown in Fig. 7 more as described above by analysis result then.

Explanation analysis result storage table make process the time, at first analyze the gradation data of the such reception of Figure 13 (a) by starting of data.Like this, wide because of font in the attribute information of first data, high and character code occurs at first, so wide, high, the character code of storage font, number of greyscale levels, size of data, data address in the analysis result storage table are set at 1 with the number of gradation data.It is such that this result becomes Figure 15 (a).Here, because the data that understand to receive are tactic with by the big beginning of gray scale, also be 8 so know the number maximum of gradation data.Second later attribute information also carried out same processing, but under the situation that font as a result is wide, high, character code is identical that exists with the analysis of front, be in their analysis result storage table of record, to increase number of greyscale levels, size of data, data address, the number of gradation data is increased by one.By the result of such processing, from the such analysis result storage table of gradation data generation Figure 15 (b) of Figure 13 (a).

Only send same character code, situation that font is wide, high though be expression as the gradation data that is sent out here, but in the situation wide in character code miscellaneous and font, that height mixes transmission, because what font was wide, high, character code is different is stored in the other analysis result storage table, thus the result just generate among Figure 16 (a)～(d) for example such a plurality of analysis results storage tables.

(S204) will be that the number of greyscale levels of display unit 68 treatable the bests is defined as transporting most and works as number of greyscale levels then as the object output of gradation data output unit 23 in optimum gradation determining unit 25.

(S205) then, extract gradation data determining unit 26 according to the analysis result that gets by gradation data analytic unit 24a, be that analysis result storage table is determined the gradation data that extracts according to the optimum gradation progression that is determined from the gradation data that receives.At this moment, judge whether the data of suitable number of greyscale levels are arranged in the gradation data receive.

(S206, S207) promptly determines the gradation data of these data for extracting if when the data of optimum gradation progression are arranged in the data that this receives.On the other hand, if there are not the data of optimum gradation progression in the data that receive, then the gradation data that is no more than the maximum of optimum gradation progression in the data that receive is determined as the gradation data that extracts.For example, when optimum gradation progression is confirmed as 8 grades of gray scales, because the gradation data that has 8 grades of gray scales in the data that receive, so this gradation data is determined as the gradation data that extracts.On the other hand, when the optimum gradation data are confirmed as 5 grades of gray scales, owing to do not have the gradation data of 5 grades of gray scales in the data that receive, will be no more than the gradation data of the maximum gradation data of these 5 grades of gray scales, the i.e. definite conduct extraction of the gradation data of 4 grades of gray scales.The address of the extraction gradation data that is determined is recorded to analysis result storage table " index of optimum gradation number " hurdle.

(S208, S209) then, gradation data extraction unit 27 takes out determined extraction gradation data by data record unit 22 by the size of data share with reference to the address of the gradation data that is write down in the analysis result storage table.At last, the extraction gradation data that will extract according to output request gradation data extraction unit 27 sends to gradation data output unit 23, and gradation data output unit 23 outputs to object output with the gradation data of this extraction.

By above-mentioned such operation, send the different multiple gradation data of number of greyscale levels, select to use best gradation data at receiver side, just may effectively utilize the high-grade data of masterpiece showing of receiver side to greatest extent.

In the above-described embodiments, when not having the data of optimum gradation progression in the gradation data that receives, extract the gradation data of the maximum that is no more than optimum gradation progression it is exported among the receiving system 2A.But, in the time of also can considering in the gradation data that receives, not have the data of optimum gradation progression, extract the gradation data of the minimum that surpasses best grey, it is transformed into optimum gradation progression exports.

Under situation about doing like this, also can be in receiving system 2A, extracting extraction unit 27 between the part of gradation data output unit 23 by gradation data, such as shown in Figure 17, gradation data converter unit 28 is set, extracts the gradation data of the minimum that surpasses best number of greyscale levels by extracting gradation data determining unit 26.

Now utilize flow chart shown in Figure 180 that the operation of the receiving system when making such formation is described simply.The gradation data supposition that receives is same as the previously described embodiments.Until judge in reception data originally, whether have the data of optimum gradation progression till, with (S301～S305) all identical till the S201 to S205 of Figure 14.Here, when having the reception data of the number of greyscale levels identical with optimum gradation progression, equally also S206, S208, the S209 with Figure 14 identical (S306, S307, S311).

On the other hand, when the reception data of not identical number of greyscale levels, extract gradation data determining unit 26 and from receive data, determine to surpass the gradation data of minimum of optimum gradation progression as extracting gradation data (S308) with optimum gradation progression.For example, when optimum gradation progression was 3 grades of gray scales, ash level data extraction unit 27 determined to surpass the gradation data of 4 grades of gray scales of number of greyscale levels of the minimum that receives this number of greyscale levels in the data as extracting gradation data.

In addition, gradation data extraction unit 27 extracts this extraction gradation data (S309) that is determined from data record unit 22, and gradation data converter unit 28 changes gray scale (S310).Then ask gradation data converter unit 28 that the data of conversion are outputed to gradation data output unit 23 by output, gradation data output unit 23 outputs to object output (S311) with the gradation data of this extraction.

Rely on such operation, in not having the reception data conditions of optimum gradation progression, can be in receiving data the gradation data of conversion be made the gradation data that is suitable for conversion most, the processing that just may show etc. at receiver side with the number of greyscale levels of the best.

And when not having like this reception data of optimum gradation progression, do not carry out same conversion, but according to circumstances as above-mentioned receiving system A, also can extract the reception data of the number of greyscale levels of the maximum that is no more than optimum gradation progression.

This situation, in receiving system 2A, between the part till from gradation data extraction unit 27 to gradation data output unit 23, such as shown in Figure 19, when being set, gradation data converter unit 28 also can directly send data from gradation data extraction unit 27 to gradation data output unit 27.

Extracting gradation data determining unit 26 is not having under the reception data conditions of optimum gradation progression, condition according to the rules will surpass the reception data of number of greyscale levels of the minimum of optimum gradation progression when the data that conversion is extracted determines as the gradation data that extracts, and the reception data of number of greyscale levels that will be no more than the maximum of optimum gradation progression when not doing conversion are determined the gradation data as extraction.

Here,, when in receiving data, not having the data of optimum gradation progression, have the data that in 2 grades of tonal ranges, surpass optimum gradation progression in the data, conversion to receive data, do not receive data like this with regard to not can conversion as receiving as the condition of afore mentioned rules.The purpose of this condition be make conversion the gray scale difference of data in 2 grades of gray scales, with the deterioration of the grade that prevents to bring because of variation.Though at this is to judge that the scope that has or not in 2 grades of gray scales surpasses the reception data of best progression, nature, this also is not limited only to 2 grades of gray scales, but the condition of afore mentioned rules can adopt various regulations.

The operation of the receiving system when utilizing the flow chart simple declaration shown in Figure 20 to have such structure below.The gradation data of supposing reception is same as the previously described embodiments.Till in the reception data of judging beginning, whether having the data of optimum gradation progression, also with Figure 14 by the identical (S401～S405) of S201 to S205, here, when the reception with number of greyscale levels identical with optimum gradation progression is counted also with S206, S208, the S209 identical (S406, S407, S413) of Figure 14.

On the other hand, under the reception data conditions that does not become the number of greyscale levels identical, extract gradation data determining unit 26 and further judge to receive whether have the data (S408) that surpass optimum gradation progression in the scope of 2 grades of gray scales in the data with optimum gradation progression.Here, when being judged as when not having such reception data, the situation of extracting gradation data determining unit 26 and above-mentioned receiving system 2A will be no more than the gradation data (S409) that the received signal of number of greyscale levels of the maximum of optimum gradation progression is defined as extracting in the same manner, and gradation data extraction unit 27 extracts the reception data (S407) that are determined.This is to the not in addition conversion of the reception data that are extracted, but according to the output request, gradation data extraction unit 27 sends to gradation data output unit 23 according to its former states, and the gradation data output unit outputs to object output (S413) with it.

Extract the gradation data (S410) that gradation data determining unit 26 is defined as extracting in the reception data of judging the number of greyscale levels that receives the minimum that will surpass optimum gradation progression when having the data that surpass optimum gradation progression in 2 grades of tonal ranges in the data, gradation data extraction unit 27 extraction these gradation datas (S411).The reception data (S412) that gradation data converter unit 28 conversion are this time extracted, gradation data output unit 23 should be exported request output these data through conversion (S413).

According to making such operation, if can receive the grade deterioration conversion seldom of data, then undertaken exporting the ability that just may maximally utilise object output after the conversion by extracting data, and under the very big situation of the deterioration that receives the data grade because of conversion, can be by the best gradation data of output in a plurality of gradation datas that transmitter side is being prepared, thus can do best processing by receiver side.

And in face the foregoing description the gradation data that sends is connected by same target data combining unit 14.Though this is can handle easily in order to be of value to receiver side, does not also hinder even do not connect gradation data, it also is feasible making each gradation data do the up time transmission.At this moment, can analyze gradation data as clue so that the character code in the attribute information that becomes link information, font height, font are wide in the receiving system side about same target.At this moment, though be offset, can simplify the structure of dispensing device at the time of reception of receiver side data.

Though will connect a plurality of gradation datas of relevant same target in the above-described embodiments, under the situation that sends a plurality of objects, connect a plurality of gradation datas of relevant object separately, also can connect these a plurality of data again by certain benchmark through connecting.For example also can connect with same one the benchmark of connecting into of character code about a plurality of transmission objects.

In the foregoing description, be equipped with in the dispensing device 1A and relate to transmission of the present invention grey data generating device 1a.Send and use grey data generating device 1a but this also can be set independently, the gradation data of the transmission usefulness of device generation thus is recorded in the recording medium of floppy disk etc., by common dispensing device it is read and send.

Figure 21 represents that the gradation data in the embodiment of the invention 2 receives the functional-block diagram of transmitting system.This gradation data receives transmitting system and is made up of gradation data dispensing device 1B and gradation data receiving system 2B.Here also supposition sends character font data as sending data, promptly sends a plurality of gradation datas about same character code, font is wide, font is high character.The data that send are not limited thereto, and this is also identical with embodiment 1.

Gradation data dispensing device 1B is obtained unit 12, same target data combining unit 14, is sent with data output unit 15, data transmission unit 16 by gradation data reading unit 11, attribute information, form with table information generating unit 17, the part of removing data transmission unit 16 constitutes to send uses grey data generating device 1b.And gradation data reading unit 11, attribute information are obtained unit 12, same target data combining unit 14, are sent with data output unit 15 and data transmission unit 16 all identical with embodiment 1.

Table information generating unit 17 obtains the attribute information of obtaining unit 12 with attribute information and combines generation as table information.The structure of expression table information among Figure 22.The situation that attribute information is obtained unit 12 and embodiment 1 similarly obtains the size of wide and high, gradation data of number of greyscale levels, character code, font as the attribute information of gradation data, also obtains the ID sequence number on the gradation data that is attached to each simultaneously.And when gradation data adds the ID sequence number, on gradation data, add the ID sequence number and obtain it.Table information generating unit 17 is in conjunction with the attribute informations of relevant this each gradation data, in the title division additional representation as the code of attribute information and generate shown in Figure 22 the table information of structure like that.The sequence consensus of attribute information and the gradation data that is connected by same target data combining unit 14.

Table information is not limited to the such structure of Figure 22, for example also can attribute information be classified by certain benchmark and carry out combination.Specifically as shown in Figure 23, for example can be wide by each identical character code, font, height classifies, make heading message, also adopt the number of greyscale levels of the gradation data that only will have these attribute informations and the ID of size of data and data to be combined into the such structure of number part.Though write down as attribute information by the id information of gradation data to carry out the corresponding of attribute information and half-tone information with each, but this also can be for example with the sequence number of the gradation data that connects as passing through in addition record of sequence number, if and the sequence consensus that is connected of the binding sequence of the attribute information of the correspondence in the table information and such now gradation data then can not have id information yet and passes through sequence number.And with id information or by when number being recorded in the table information, need not to combine with same sequence number with the corresponding grey of attribute information of table information.

Gradation data receiving system 2B is made of Data Receiving unit 21, gradation data output unit 23, gradation data analytic unit 24b, optimum gradation determining unit 25, extraction gradation data determining unit 26 and gradation data extraction unit 27.Data Receiving unit 21, gradation data output unit 23, optimum gradation determining unit 25, extract all identical with relevant embodiment 1 of gradation data determining unit 26, gradation data extraction unit 27.

Gradation data analytic unit 24b analyzes according to the number of greyscale levels of the gradation data that the aforementioned table information butt joint of gradation data dispensing device 1B is received.At this moment, the situation with embodiment 1 similarly generates analysis result storage table such shown in Figure 24 based on analysis result.This analysis result storage table and the storage of analysis result shown in Fig. 7 table different being in write down the ID of gradation data in the data address of the gradation data that replaces each and replace the data address of extracting gradation data and write down the ID that extracts gradation data.Analysis result storage table be not limited thereto structure, then similarly to Example 1.In table information, replace the ID of gradation data and record connection gradation data pass through along number the time, the ID of replacement gradation data passes through sequence number and write down this.Even record is not by sequence number, but in table information, during the sequence consensus that is connected of the binding sequence of corresponding attribute information and gradation data, also to pass through sequence number with the journal of the attribute information in the analytical table information.

The operation that gradation data with above structure is received transmitting system describes below.At first according to the operation of flowchart text transmitter side of the operation that shows the dispensing device of gradation data shown in Figure 25 1B.

Is to send three kinds the gradation data group X about 2,4,8 grades of gray scales of character " pressure " shown in Fig. 9,10,11 at this as sending object, supposing.

The situation of (S501, S502) and embodiment 1 similarly, read the gradation data group X that constitutes by a plurality of gradation datas shown in Fig. 9～11 at transmitter side with gradation data reading unit 11, with attribute information obtain unit 12 obtain about read the attribute information of each gradation data.The information that obtains in embodiment 1, enumerate, also obtain the id information of each gradation data.Here the id information of supposing each gradation data is respectively " 0001 ", " 0002 ", " 0003 ".

(S503), same target data combining unit 14 connect read a plurality of gradation datas.Here still also be to connect each gradation data with sequence arrangement from the big beginning of number of greyscale levels.The data that this result generates show in Figure 26 as concept map.

(S504) then show information generating unit 17 in conjunction with the attribute information of obtaining, generate table information.This binding sequence order of connection with the corresponding grey scale data that connected with same target data combining unit 14 as described above is consistent.The table information representation that the result generated is in Figure 27.

(S505, S506) sends with data output unit 15 and at first the table information that is generated made and can output to data transmission unit 16 with data with the transmission that data transmission unit 16 sends such form, and the data transmission unit 16 that receives it sends to gradation data receiving system 2B with this table information.

(S507, S508) sends with data output unit 15 gradation data through connecting made and can export toward data transmission unit 16 with data with the transmission of the such form of data transmission unit 16 transmissions, and the data transmission unit 16 that receives it sends to gradation data receiving system 2B with this gradation data.Here, data transmission unit 16 transmission table information when sending gradation data is sending through behind the official hour.

Following basis shows the operation of flowchart text receiver side of the operation of the receiving system of gradation data shown in Figure 28 2B.

(S601) at receiver side, at first Data Receiving unit 21 receives such table information shown in the Figure 27 that is sent out.

(S620) gradation data analytic unit 24b analyzes the table information that receives.Gradation data analytic unit 24 makes the analysis result storage table of such form shown in Figure 24 more as described above from the result who analyzes.

The process that makes of analysis result storage table is roughly the same with the process that makes of the analysis result storage table of relevant embodiment 1, initial analytical table information by data, the font that initially occurs is wide, high, and character code deposits analysis result storage table in, and the number of gradation data is set at 1.Then second later attribute information also carried out same processing, but exist with before the font as a result of analysis wide, high, when character code is identical, in addition number of greyscale levels, size of data and data ID in their analysis result storage table of record, and the number of gradation data increased 1.Because knowing here the data that receive also is tactic with by the big beginning of gray scale, also is 8 so know the number maximum of gradation data.The result of such processing is the such analysis result storage table of gradation data generation Figure 19 by Figure 27.

Though be to show only to send same character code, the situation when font is wide, high as the gradation data that is sent out here, and, height wide in various character codes, font mixes under the situation about being sent out, similarly font is wide, high, character code is inequality is stored in other analysis result storage table with the situation of embodiment 1, so generate a plurality of analysis result storage tables is arranged.

Here in table information, record the id information of each gradation data, but under recording the situation of passing through sequence number of gradation data, write down the sequence number of passing through of gradation data in the analysis result storage table.Even and by under the also Unrecorded situation of sequence number, here because the order of the attribute information in the corresponding table information is consistent with the order of gradation data, so also can pass through sequence number by the journal of reading attribute information by table information.

(S603) in optimum gradation determining unit 25, the treatable optimum gradation progression of object output of gradation data output unit 23 is defined as optimum gradation progression.

(S604) extract gradation data determining unit 26 according to by gradation data analytic unit 24b gained result, be analysis result storage table, determine in the attribute information of the gradation data that from table information, is write down based on the gradation data that extracts of fixed optimum gradation progression.At this moment, judge the data that whether have optimum gradation progression in the attribute information of the gradation data that table information is write down.

(S605, S606) if show the gradation data that optimum gradation progression is arranged in the attribute information of the gradation data that the table information is here write down, just the gradation data that this gradation data is defined as extracting.On the other hand, as showing the gradation data that does not have optimum gradation progression in the attribute information, the gradation data that then is no more than the maximum of optimum gradation progression in the gradation data that attribute information is represented is determined as the gradation data that extracts.At this, for example suppose that the gradation data of 4 grades of gray scales is determined as extracting gradation data.The ID of the extraction gradation data that is determined is recorded in " ID of optimum gradation data " hurdle of analysis result storage table into.

(S607) Data Receiving unit 21 receives the gradation data through connecting that is sent out from gradation data dispensing device 1B.

(S608) id information of the gradation data that write down with reference to analysis result storage table of gradation data extraction unit 27 extracts the extraction gradation data that is determined of corresponding gradation data in a plurality of gradation datas that connecting that from then on receive.Here because be the gradation data of 4 grades of gray scales is determined as extracting gradation data, so 27 references of gradation data extraction unit as " 0002 " of the id information of the gradation data of 4 grades of gray scales that write down in the analysis result storage table, are extracted the gradation data of the id information with " 0002 " from a plurality of gradation datas that receive.

The situation of passing through sequence number that records gradation data in analysis result storage table is will manage to extract target data from the size of data of each gradation data and the number that passes through of extraction gradation data.For example, extracting gradation data now is the gradation data of 4 grades of gray scales of second, in analysis result storage table as being No. 2 by number record.Thereby gradation data extraction unit 27 extracts second data from the gradation data that is bonded.Because the size of first data is 96, thus the size of data by from the address of jumping over 96 of starting of the gradation data that is sent out certainly, reading 4 grades of gray scales promptly the data of 64 shares extract the data of 4 grades of gray scales.

(S609) according to the output request extraction gradation data that gradation data extraction unit 27 extracts is sent to gradation data output unit 23, gradation data output unit 23 is with the past object output of it output.

Rely on such operation, send the different multiple gradation data of number of greyscale levels similarly to Example 1, select to use best gradation data, promptly may maximally utilise the high-grade data of masterpiece showing of receiver side thus at receiver side.And owing to analyze attribute and id information or the order that can know gradation data in advance by the table information of the gradation data that previous reception is sent, so might only be taken into required gradation data, thereby can further cut down the capacity of memory and simplify processing than the situation of embodiment 1.

Among the embodiment 2, when in the gradation data that as embodiment 1, receives, not having the data of optimum gradation progression, also be to draft the gradation data that will extract the minimum that surpasses best number of greyscale levels, its data that are transformed to optimum gradation progression are exported, under situation about doing like this, still in receiving system 2B, between part from gradation data extraction unit 27 to gradation data output unit 23, such as shown in Figure 17, gradation data converter unit 28 is set, can extracts the gradation data of the minimum that surpasses best number of greyscale levels by extracting gradation data determining unit 26.

Do not having not do same conversion under the reception data conditions of optimum gradation progression, but can extract the reception data of the number of greyscale levels of the maximum be no more than optimum gradation progression according to situation, this situation during also with embodiment 1 equally in receiving system 2B, from gradation data extraction unit 27 between gradation data output unit 23 parts, such as shown in Figure 19, gradation data converter unit 28 is set, can directly sends data to gradation data output unit 23 from gradation data extraction unit 27 simultaneously.

Operation when doing like this because of with the illustrated operation of embodiment 1 usefulness mutually, its explanation of Therefore, omited.

Though connect gradation data in the foregoing description, as on gradation data, add link information, prevent even do not connect also not have, also can send each gradation data naturally in turn.

The code of additional representation attribute information on the table information in the foregoing description, if but for example inevitable order transmission with the gradation data on the attribute information on first, second etc. pre-determine sending order, then because recognize that first data are that attribute information, data thereafter are gradation data, so do not indicated it also is self-evident especially.Though and be at the additional code that representation attribute information is arranged of table information side here, can certainly at the code of gradation data side additional representation gradation data.

In addition, though here so that time difference transmission table information and gradation data to be set, but as in gradation data receiving system 2B, data record unit similarly is set with the situation of embodiment 1, also just can arbitrarily determine to send the timing of table information and gradation data, also table information can be combined with gradation data and send.

Can also will not send in the same manner with being contained in the grey data generating device 1b among the dispensing device 1B with embodiment 1, use grey data generating device 1a but independently be provided with to send, the transmission that device is thus generated is recorded on the recording medium of floppy disk etc. with gradation data, and relies on common dispensing device that it is read and sends.

First gradation data among Figure 30 in the expression embodiments of the invention 3 receives the functional-block diagram of transmitting system.This gradation data receives transmitting system and also is made up of gradation data dispensing device 1c and gradation data receiving system 2c.Receive a plurality of gradation data that sends for character string among the embodiment 3.

Gradation data dispensing device 1c is obtained unit 12, attribute information extra cell 13, same target data combining unit 14c, is sent and form with data output unit 15, data transmission unit 16, textual data reading unit 18, gradation data extraction unit 19a and gradation data memory cell 19b by gradation data reading unit 11, attribute information, and the part of removing data transmission unit 16 constitutes to send uses grey data generating device 1c.And gradation data reading unit 11, attribute information are obtained unit 12, attribute information extra cell 13, are sent with data output unit 15 and data transmission unit 16 all identical with embodiment 1.

Textual data reading unit 18 is for reading the part of textual data.Read sequence at this as the character code of each character of the formation text of textual data.Textual data reading unit 18 is exported the textual data that reads in to sending with data output unit 15, send with data output unit 15 this textual data is also outputed to data transmission unit 16 as sending with data.

Gradation data memory cell 19b deposits a plurality of gradation data of the character that relevant character code represents to the alphabet code.Here supposition is the gradation data of storage secondary gray scale, 4 grades of gray scales and 8 grades of gray scales about each character code.

Gradation data extraction unit 19a extract corresponding to constitute textual data reading unit 18 read textual data each character, be a plurality of gradation datas of each character code, export to gradation data reading unit 11.

Same target data combining unit 14c is the part that connects a plurality of gradation datas similarly to Example 1, but at first be with about a plurality of gradation datas of each character code by being linked in sequence of the big beginning of number of greyscale levels, again this is connected data by little being linked in sequence of character code.If similarly link information is attached on the gradation data, then need not makes gradation data and connect, and can adopt various types of attachment with the situation of embodiment 1.

Gradation data receiving system 2c is made up of Data Receiving unit 21, data record unit 22, gradation data output unit 23c, gradation data analytic unit 24a, optimum gradation determining unit 25, extraction gradation data determining unit 26 and gradation data extraction unit 27.Data Receiving unit 21, data record unit 22, gradation data analytic unit 24a, optimum gradation determining unit 25, extract all identical with relevant embodiment 1 of gradation data determining unit 26 and gradation data extraction unit 27.

Gradation data output unit 23c is according to the textual data that is sent by gradation data dispensing device 1c, i.e. the gradation data that extracts with the output gray level data extracting unit 27 that puts in order of character code.

Illustrate below that then the gradation data with above structure receives the operation of transmitting system.At first, according to the operation of the flowchart text transmitter side of the operation of the gradation data dispensing device 1c of expression shown in Figure 31.

Here supposition will be about the text receipt of " ぁぃラ " character string as sending object.Be respectively " OX2422 " " OX2424 " " OX2426 " according to the character code that constitutes about the Japanese Industrial Standards of each character of the character string of this " ぁぃラ ", it is such that textual data becomes Figure 32.

(S701, S702) reads the textual data shown in Figure 32 by textual data reading unit 18, and gradation data extraction unit 19a is from a plurality of gradation datas of gradation data memory cell 19b extraction corresponding to each character code that constitutes textual data.

(S703～S705) similarly to Example 1, gradation data reading unit 11 reads a plurality of data that are extracted, attribute information code fetch unit 12 obtain relevant read the attribute information of gradation data of each gradation data.Then, attribute information extra cell 13 additional corresponding attribute information on gradation data separately.Here also with attribute information as heading message, with the title of its additional gradation data as separately.Here the attribute information of gained is shown in Figure 33 (a)～(i) for example.

(S706) same target data combining unit 14 connects relevant to the additional gradation data separately that the same character code of attribute information is arranged.That is, become and each gradation data that all is connected of character code that constitutes textual data.At this also as described above, make each gradation data by being connected by the sequence arrangement of the big beginning of number of greyscale levels, the data with this connection are connected by the order by the little beginning of character code again.The result who connects is shown among Figure 34 conceptually.

(S707～S709) transmission makes connected gradation data and textual data can be exported to data cell 16 with data by the transmission of the such form of data transmission unit 16 transmissions with data output unit 15, and the data transmission unit 16 that receives it sends to gradation data receiving system 2c with this textual data and gradation data.

Below according to the operation of the flowchart text receiver side of the operation of the gradation data receiving system 2c of expression shown in Figure 35.

(S801～S803) at receiver side, Data Receiving unit 21 receives textual data and the gradation data that is sent out.Then the data record that this is received is to data record unit 22.

(S804) gradation data analytic unit 24a analyzes the attribute information that is attached on the gradation data that receives.Gradation data analytic unit 24a is made the analysis result storage table of such form shown in Fig. 7 more as described above to each character code by the result who analyzes.As above-mentioned, because different being stored in the other analysis result storage table of character code, so the result who handles just generates three analysis result storage tables corresponding to such each character of " ぁ " " ぃ " " ラ " of Figure 36 like this.

(S805～S808) determine optimum gradation progression by optimum gradation determining unit 25 in the same manner with embodiment 1 determines the gradation data of the extraction of relevant each character code by extracting gradation data determining unit 26 according to the optimum gradation number.The address of the extraction gradation data that is determined is recorded to the index edge of the optimum data of analysis result storage table.

(S809, S810) gradation data extraction unit 27 takes out the extraction gradation data that is determined with reference to the address of the gradation data that is write down in each character code analysis result storage table by data record unit 22 by size of data.At last according to output request gradation data extraction unit 27 to gradation data output unit 23 send extract gradation data, gradation data output unit 23 puts in order these gradation datas and exports to object output by the character of textual data.This result just can erroneous arrangement " ぁぃラ " character ground, in object output, show each character of formation " ぁぃラ " etc. with appropriate number of greyscale levels.
