This invention relates to an image editing apparatus for retrieving and processing plural image parts and synthesizing them to a synthesized image, especially to the one to transfer the contents of natural language imput to a synthesized image.
In recent years, with the spread of word processor, it became possible for anybody to make a document so pretty as typeprinting. And, keeping step with this, there is eager demand for a function as to make easily illustration or synthesized image and take it into a document prepared by the word processor.
While, it has been put to practical use to arrange plural image parts on a background image and to edit to one synthesized image.
As a rudimentary method, in the past, functions to draw elementary figures such as a straight line, curve or circle and functions capable of applying simple process thereto were prepared, and these functions were properly combind to make various illustrations or figures. Further, it has been also practiced to store as parts the illustrations, figures or images made by the above described functions, to utilize again to improve the operation efficieny.
For the forming of more complicated synthesized image, it has been necessary, as a rule to store parts of images, to take out them by retrieving, and to combine and edit them retouching the parts or synthesizede images, if necessary.
Referring to the storing and retrieving of image parts, which comprises preparing plural image parts and background images and retrieving them one by one in accordance with the necessity for editing, various methods have been used; a method to use key words, and a method to store the images arranging them to upper and lower class relation, and to trace the relation looking at retrieved images from the top of the class relation to narrow down to the intended image.
As for editing, a procedure to enlarge or to reduce, for example, these background images and image parts, and a procedure to synthesize the parts on the background images were made independently by human agency, requiring complicated operation of input apparatus of a key board or mouse.

DESCRIPTION OF THE PREFERED EMBODIMENT OF THE INVENTION Now, referring to drawings, an embodiment of the present invention is explained below.
FIG. 1 shows a block diagram of hardwave structure of an embodiment of an image editing appatatus according to the present inventions.
The apparatus includes a language-image-uniting dictionary 101 consisting of; a first storing means, a second storing means; and a fourth storing means; a grammer dictionary 102 which is also a third storing means; an image editing rule 103 which is also a fifth storing means, and they are put together in a storing media such as a hard disk. The image editing apparatus further includes; a language inputting means 104 with which the user inputs information by means such as a keyboard, combination of acoustic input means and speech recognition means as well as a keyboard; an image displaying means 105 which displays edited image; an image revising means 106 with which the user revises the image; an image registrating means 107 which registrates the edited images; a parsing means which parses a sentence being input by the language inputting means 104, using the language-image-uniting dictionary 101 and the grammer dictionary 102; an image retriving means 109 which retrieves an image information using the result of parsing of input sentence; and an image editing means 110 which edits the image, using the parsing result of the input sentence, retrived image information and the image editing rule 103 and, based upon the meaning and contents of input sentence.
FIG. 2 and FIG. 3 are examples of description of not-yet-edited image information on example of an image part and a background image respectively. The not-yet-edited image infotmation consists of instance valve (201 in FIG. 2 and 301 in FIG. 3) and image data (202 in FIG. 2 and 302 in FIG. 3). The instance value includes in case of image part, as shown in FIG. 2, name 203 of image information, image attribute 204, background image 205 of default, size 206 of the object expressed by the image, and data area 207 of the image data, for example, and, in case of background image, as shown in FIG. 3, name 303 of image information, image attribute 304, size 305 of the object expressed by the image, and the center position 306 of the image data, for example. While the image data is expressed by a line drawing for convenience of explanation in this example, data such as color information of image element or shape information is by some method like this example, tranformed to data of character and numeral, to be stored.
FIG. 4 and FIG. 5 show description of edited image information on examples of image part and background image respectively. The edited images are formed with attribtes 401 or 501 only. The attributes comprisis, in case of the image part, as shown in FIG. 4, name 402 of the image information, image attribute 403, background image of default and its position 404, size 405 of the object expressed by the image, data area 406, and location 407 of the images used for editing, and, in case of the background image, as shown in FIG. 5, name 502 of the image information, image attribute 503, size 504 of the object expressed in the image center position 505 of the image data, and location 506 of the images used for editing.
FIG. 6 shows an example of image editing rule 103 as a flow chart, in which enlarging, reducing and positioning among editing procedure are made. In the following, an example of the procedure is explained, which, starting from the relation "There is a C on the B which is in the A", enlarge B and reduce C, arrange B in A, and put C on B.
First, image information and result of parsing input sentence which are necessary for editing procedure are input (Step 14). As the result of parsing, formula (4) for example shown later is used. Input data 601 is expressed in FIG. 6 for easy understanding.
Then, whether the sizes of B and C is appopriate with reference to the background image A is judged considering attributes of A, B and C (Step 15). If it is appropriate, the procedure jumps to step 17, and, if not, it jumps to step 16 and, after adjusting the size of image information B and C, jumps to Step 17. Further, it is judged (Step 17) referring to instance value of image information B and C, whether the size of C is adequate or not compared with B. If it is so, the procedure jumps to Step 19, and if not, to Step 18 and, adjusting the size of image part C, to Stop 19. Lastly position of image part B is determined so as to satify positinal relation "in" with reference to the background image A, and position of image position C is determined so as to satisfy positional relation "on" with referene to the image position B. In this case, though not shown by the image parts in FIG. 2 and FIG. 3, it is preferred to describe in A and B the positions of default corresponding to the positional relation "in" and "on", and to determine the position B and C so as to match to the input positinal relation. The resuts is represented, for example, as formula (1);
scene (A)
parts (B, mag1, x1, y)
parts (C, mag2, x2, y)                                     (1)
The meaning of formula (1) is;
Designate the background image A
Reduce image part B by the factor mag 1, and put at (x1, y) on the background image A.
Reduce image part C by the factor mag 2, and put at (x2, Y) on the background image A.
The editing rule was shown by a flow chart in this case for convenience of explanation. Usually, such control is transferred to a program by using procedural language or logic language and put into the apparatus.
An example of procedure of image editing by use of image editing apparatus as constructed as described is explained below, referring to the flow chart of FIG. 7. The example of input sentence is:
"There is an apple on the table"                           (2)
First, the procedure up to the parsing of input sentence and retrieving of image is explained. The natural language sentence (2) is input by the language input means 104, and sent to the language parsing means 108 (Step 1), where the input language (2) is parsed with the language-image-uniting dictionary 101 and the grammer dictionary 102 (Step 2), to draw out (Step 3) simple words "table" and "apple" necessary for the image editing.
In the parsing means 108, input sentence (2) is parsed with the grammar dictionary 102, an example of which is as follows: ##EQU1##
If a sentence "S" is inputted, it is parsed, according to the above grammar, into non-terminal symbol "NP", "VP", etc., and, by being parsed further to terminal symbol such as "N", "V", it is received as a sentence.
The sentence (2) is parsed as shown in FIG. 28 and, by matching the words "There", "apple", and "table" with the language-image uniting dictionary, "apple" and and "table" which are expressible as images are drawn out.
With the image retrieving means 109, images expressing the drawn simple words are retrieved (Step 4). Further, with the parsing result obtained at Step 2, it is checked whether the positional relation of the simple word drawn out at the Step 3 is drawn or not (Step 5). For example, the result obtained by parsing the input sentence (2) and by drawing the simple word necessary for image editing and the positional relation thereof is expressed as follows;
Attribute (B, table)
Attribute (C, apple)
on (B, C)                                                  (3)
If the positional relation is not drawn at Step 5, the procedure jumps to step 6, where the images drawn at Step 4 are all expressed, to finish the procedure.
The preliminary process of image editing at the image editing means is explained below.
First, from the parsing result (3) image information which is to become a main part is determined (Step 7). The main part means an image part which works as base when parts are arranged on a background image. In the case of sentence (2), as is understood from the parsing result (3), "table" is the base for arranging "apple", so that, "table" becomes the main part.
Then, from the parsing result, whether any image which is to be a background image exists is checked (Step 8). If it is not found, the background image to be used as default is retrieved from the attributes in the image information of the main part (Step 9), and the procedure jumps to Step 10. If it is found, the procedure jumps to Step 10, where, if the example of the figure is adopted as the image information of "table", "room" is obtained as the background image information. Thus, the following data necessary for image editing is obtained.
Attribute (A, room)
main-- part (B)

Lastly, with data (4) appled as input, editing procedure of image is carried out by an image editing means 110. In the image editing means 110, the image editing rule 103 (as shown by example in FIG. 6) is called from "on (B, C)" among the input data (4), and the arrangment data (1) of image parts on the image part A results (Step 10). Further, by the arrangement data (1), the edited image is displayed by the image displaying means 105 (step 11). Whether the obtaind image is satisfactory is judged (Step 12), and, if it is, the procedure ends. If not, the procedure jumps to Step 13, where image parts in the obtained image is retrieved--enlarged, reduced, moved, or rotated, to finish the procedure by an image revising means 106.
Thus, according to the first invention, with input in natural language representing the contents of images to be edited, intended images can be obtained automatically, reducing the load of operator in image editing.
Next, an embodiment of the image editing apparatus acoording to the second invention of the present invention is explained, referring to the drawings.
FIG. 8 is a block diagram showing the structure of an embodiment of the image editing apparatus according to the present invention. The image editing apparatus comprises a parsing dictionary 801; an image data storing-managing means 805 comprising an image retrieving dictionary 802, a class data management system 803, and an image data base 804; language input means 806, a parsing means 807, an image retrieving means 808, an image processing means 809, an image synthesizing means 810, an image displaying means 811, and image synthesis knowledge base 812.
FIG. 9 to FIG. 11 show examples of discription of an image retrieving dictionary 802, a class data of a class-data-management system 803, and an image part of image data base 804, which constitute the image data storing-managing means 805.
FIG. 9 describes an image retrieving dictionary 802 according to the invention in table form. The image retrieving data 903 is composed of a description part 901 of the image retrieving word and a description part 902 of the pointer to appoint the class data representing the class of the image retrieving word, and, in this example, class data is used as a pointer to appoint the class data expressing the class of the image retrieving word.
When nouns which are expressible as images are registered as image retrieving data 903 in a image retrieving dictionary 802, whether an image part expressing noun exists or not is judged only if the existence of image retrieving word corresponding to the noun is searched. For example, in FIG. 9, since nouns "table", "Table", "TABLE" are all registered as image retrieving words in the image retrieving dictionary 802, the image parts expressing these nouns is judged to exist. That is, in retrieving an image part expressing "table", three simple words "table", "TABLE", and "Table" are usable. As for the method to retrieve image part expressing the above described noun, description is given later at the explanation on the image retrieving means 808.
FIG. 10 to FIG. 13 shows the class data according to the present invention in a form of list.
A class data consists of a description part 1001 of a class name, a description part 1002 of a pointer pointing the class data representing upper class, a description part 1003 of a pointer pointing the lower class, a description part 1004 of a pointer pointing an image parts expressing the substance of the said class, a description part 1006 of method to give processing to the said image part, and a description part 1005 of a variable necessary for the said method. In the following, the contents of the description parts are explained referring to the example of "table" shown in FIG. 10 and class data of room" given in FIG. 11.
"SuperClass" and "SubClass" are embodiments of the description parts (1002 and 1003) of pointers pointing the class data expressing upper class and the class data expressing lower class. In the embodiment the said name "class data" is used as a pointer to point the upper and lower class data. If any coresponding class data does not exist, it is represented by "nil". For the class data "table" in FIG. 10 "furniture" is appointed as the upper class data "SuperClass", whereas the lower class data "SubClass" is represented as nil, since it is difficult to divide "table" conceptionally further. Also, for the class data "room" in FIG. 11, "house" is appointed as the upper class data "SuperClass", and "kitchen", "living room", and "bed room" are appointed as the lower class data "SubClass".
"Image" expresses an embodiment of the description part 1004 of the pointer which points out the image part showing the actual situation of class data according to the present invention and the pointer is given the name of the file storing the data of the said image parts. In the class data "table" in FIG. 10, it is appointed as
(Image IM#table1 IM#table2 IM#table3)
This means that all the character strings following the "Image" and beginning with IM# and in the parenthesis are the files including image parts expressing the class of class data, and that there are IM#table1, IM#table2, IM#table3 etc. as the file including image parts expressig "table".
"Method" represents an embodiment of the description part 1006 of method in the class data according to the present invention, and described by an format;
(name of method declaration of parameter contents of method).
In the class data "table" in FIG. 10, "ComposeParts" is the name of the method, "Relation" and "ClassName" in a following parenthesis are the parameter of the method "ComposeParts" and the parts further following up to the parenthesis coresponding to the parenthesis just before "ComposeParts". "ComposeParts" is an example of method to execute the synthesis of image automatically according to the invention, the contents of the precedure being explained later in the explanation on image synthesizing means 810.
"Slot" represents the example of the description part 1005 of variable in the class data according to the present invention, and described by a format:
(type of variable name of variable�name of variable).
If the initial value of a variable is necessary, the part of the above "name of variable" is changed to (name of variable initial value). In the class data "table" in FIG. 10, variables of three type "Posision", "DefaultBG", and "PositioningVerb" are declared.
A Variable declared by the "Position" type is used in the above described method "ComposeParts", and four types:
P-- on P-- under P-- right and P-- left
are declared. As initialization is not made for them, it is necessary to appoint concrete value in the image part belonging to the class data "table".
The variable "default-- bg (311) declared in "DefaultBG" type is an example of a variable for distinguishing which of the background and object is expressed by the said class data. Class data for which the variable 1011 of "DefaultBG" type is declared represents the object, and class data not declared represents the background. For the case of class data "table" in FIG. 10, the variable default-- bg (1011) declared by DefaultBG type is initialized as
DefaultBG (default-- bg (C#room in)),
This means that "table" is the foreground object and is put at "in" of "room". Also, for the class data "room" of FIG. 11, which is a class representing background object, this variable is not declared. If the background object of a class data is not appointed as "apple" of FIG. 12 or "orange" of FIG. 13, it is enough to indicate that the variable 1011 of "DefaultBG" type is declared as;
DefaultBG (default-- bg nil)
This nil is used when the class data is not appointed to be at any background object. When it is requested to classify the class data into smaller groups according to attributes such as shape, color, etc., it is not necessary to make under class in the description part 1003 of the pointer apointing the class data exspressing the lower class, but it is done by declaring the variable to distinguish the said attribute at the description part 1005 of the Slot of class data, and describing concrete value of the variable at each image parts which belongs to the class data. For instance, if class data "table" needs more detailed classification referring to their shaps or colors, the variable to distinguish shape or color as
(Shape shape)
(Color color)
is declared at he description part 1005 of the Slot of "table", and, at the image parts belonging to the class data "table", the concrete value of the variable is described as;
(Shape square)
(Color brown)
FIG. 14 to FIG. 17 show the general ideas of image parts used in the present invention. The image parts consists of description part 1401 of instance value and image element data 1402. In the following, with the example of a image part representing "table" shown in FIG. 14, the contents of instance value and image element data are explained.
Among the variables declared by the class data to which the image part belongs, not-initialized one is given concrete value, by the description part 1401 of instance value. In the present case, concrete values are given to the four variables not-yet-initialzed by the class data "table" in FIG. 10. Further, in the image part to express "table", concrete values are given to the two variables, data-- size and actual-- size (1410, 1411). These are the example of variable 1410 (data-size) representing the size of image element data of image part and variable 1411 (actual-- size) representing the size of the object represented by the picture parts according to the invention, and they are not declared in the class data "table" to which the image part belongs. They are special variables inherent to the all image parts, declared at the class data at the top of the class data in a classified relation, and considerd as omitted in the class data "table" as the result of succession of the variable of the present invention. On this subject description is made later at the explanation on image processing means 809, as well as the method "CalcZoomRatio" described by the highest class data likewise.
On the contrary, as default-- bg of the class data "table" in FIG. 10 is already initialized in class data, it is not necessary, for the image parts belonging to class data "table", to appoint concrete data anew, exept under some special situation. If special appointment is necessary, description is:
(default-- bg (C#garden in))
Thus, the explanation of an embodiment of the image data storing-managing means 805 according to the present invention ends.
In the following, referring to FIG. 8, procedure and flows thereof in various means in the image editing apparatus according to the present invention are explained with:
There is an apple on the table which is in the room.       (5)
as an example of input.
First, the example sentence (5) is input by the language input means 806, and transferred to the parsing means 807. As the language input means 806, a keyboard for instance is used.
In the parsing means 807, information for synthesizing automatically the image from the input sentence is retrieved and formed, and stored in the image editing data storing means 812. The procedure in the parsing means 807 is explained below with reference to the FIG. 18, showing the procedure in flow chart.
First, the parsing of the input sentence is made (Step 1801) with a parsing dictionary 801, and objects wihich is expresible as image, information which shows the attributes thereof, and relation between the objects are drawn out (Step 1802). For the parsing (Step 1801), Definite Close Grammer for example may be used.
The judgement of possibility of expressing as image the noun drawn out by the morphological analysis according to the present invention may be done by checking whether the image retrieving data 903 having the image retrieving ward coinciding with the noun is registered in the image retrieving dictionary 802. That is, if the image retrieving data 803 having the image retrieving word coinciding with the noun is registerd in the image retrieving dictionary 802, the noun is determined to be pictorially expressible. As for the relation between the objects drawn out in the parsing means 807, various types can be thought of. In the present embodiment, however, a case dealing with the positional relation and one dealing with the movement are shown. The positional relation has as its basic data structure the triple set;
(object positional relation object),
which shows that the object of the third article lies at the position of the second term with referrence to the object of the first term. Also, the movement relation, likely as the positional relation, has as its basic data structure the triple set;
(object movement relation object)
which shows that the object of the third term does the movement of the second term against the object of the first term. In the follwing, this data structure is called the basic relation list. The basic relation list which was drawn for the sentence (5) is
((C#room in C#table)
(C#table on C#apple)),
which shows that the position of "table" with referrence to "room" is "in", and that of "apple" with referrence to "table" is "on". When an attribute information to modify the object is given in the input sentence, it is drawn out at the same time in this procedure. For instance, for the sentence
"There is a green apple on the table which is in the room",
the basic relation list drawn out is:
((C#room in (C#table (shape round)))
(C#table on (C#apple (color green))))
As is observed, in the basic relation list the attribute information is expressed combined with the object. In passing, from C#table in the second basic relation list, attribute information is omitted since it is the same as that in the first list. If the object is different, it is distinguished by newly giving the attribute information. For example, for the sentence
"There are a green apple on the right of a round table, and a red apple on the left of the round table.",
the drawn out result of the basic information list is as follows;
(((C#table (shape round)) right (C#apple (color green)))
(C#table left (C#apple (color red))))
Next, from the basic relation list drawn out by the above procedure, a tree structure representing, the objects and the relation therebetween is formed (Step 1803). The tree is formed, by representing, on all the basic relation list drawn out as above described, the objects and relations by node and link, respectively (This is called the basic tree), and repeating the process to unify the node representing the same object together until the tree becomes one. If there is any attribute information to modify the object, it is described in the node representing the object as well. The basic relation list drawn out from the sentence (5) is transformed to a basic tree as shown in FIG. 19. As the node representing "table" is included in both the basic trees, they are put together to one. Thus, obtaining only one tree, the tree forming procedure ends.
The tree is transferred to the image synthesis knowledge base 812 (Step 1804), to finish the procedure in the parsing means 807.
Returning to FIG. 8; in the image retrieving means 808, the class data, in which the data on the object are described, and the image part, which represents the object, are retrieved. In the procedure, the class data in which the object data are described are retrieved using the name of the object of each node of the tree memorized in the image synthesis knowledge base 812 as the key word. The image parts representing the object and the method to process them are described in the class data, to be referred to. The retrieving is done by searching in the image retrieving dictionary 802 an image retrieving data which has the image retrieving word coinciding with the keyword, and following up the pointer appointed by the image retrieving data. IN the tree in FIG. 20, "room", "table", and "apple" are included as nodes, so that, using these as the keyword, the class data can be traced in the image retrieving dictionary 802. All the class data retrieved are transferred to the image synthesis knowledge base 812. In parsing, if the attribute in formation for modifying the object is described in each node, likelyhood showing the degree of coincidence of the retrieved image parts representing the class of the class data to the input attribute can be estimated. For that purpose, the method described in Japanese patent application No. Hei 3-255025 for example is applied. Thus, the procedure in the image retrieving means 808 is over.
Referring to FIG. 8, again, the procedure in the image processing means 809 is explained. In the image processing means 809, the processing of the image parts retrieved in the image retrieving means 808 is carried out. FIG. 21 shows the flow of procedure in the image processing means 809. Now, the method "CalcZoomRatio" declared in the class data ranked to top, and the method to calculate magnitude of enlarging or reducing each image part are explained, referring to FIG. 21, and using the tree in FIG. 20 made for the sentence (5), which was used in the explanation of the language parsing means 807.
To the begin, one image part which represents the class of root node of tree is selected, and the data-size of the image part is denoted by Xs and Ys, and the actual-size by S (Step 2101). Since the root node of the tree is "room" from FIG. 20, if, as the image parts belonging to it, those in FIG. 15 are used,
Xs=640
Ys=400
are obtained. Also, assuming n as the number of nodes other than the root node of the tree, the nodes are given number from one to n (Step 2102). In FIG. 20, as the number of nodes other than the root node of the tree is 2, n=2 and nodes "table" and "apple" are given number 1 and 2 respectively.
Then, putting i=1 (Step 2103), an image part expressing the concept of the i-th node is selected, and data-- size and the actual-size of the image part are denoted by Xd, Yd and D, respectrively (Step 2104). As, in this case, i=1, using, the image part in FIG. 14 as the first node i.e. the image part representing the concept of "table",
Xd=256
Yd=128
And, with respect to a image part representing the class of root node of a tree the magnitude of enlarging or reducing other image part representing the concept of the i-th node is calculated by a formula as given in FIG. 22 in the method "CalcZoomRatio". In the formula, rmax and rmin are the threshold value to modify when the value of rcal is too large or too small, and if rcal >Fmax, rcal is replaced by rmax, and if rcal <rmin, rcal is replaced by rmin. For that purpose, rmax and rmin are given appropriate value beforehand. As i=1 now, calculation of magnitude r1 of enlargeing and reducing of "table" with reference to "room" results in r1 =0.7.
Further, the data-- size of the image part representing the concept of the i-th node and the attribute of the Position type variable are multiplied by ri, and, as for the image element data, the length and breadth are both multiplied by ri as well (Step 2106). Here the following transformation of data for the image parts representing the concept of "table" is applied.
______________________________________(data-- size           256*0.7         128*0.7)(P-- on    x1*0.7          y1*0.7)(P-- under x2*0.7          y2*0.7)(P-- right x3*0.7          y3*0.7)(P-- left  x5*0.7          y5*0.7)______________________________________
Now, as i<n (Step 2107), i is increased by 1 (Step 2108) (that is, i becomes i=2), and, returning to Step 2104, similar procedure is applied, that is, the magnification r2 of enlarging or reducing the image part of "apple" with referrence to the image part of "room" is calculated. When it is over, judging i<n (Step 2107) proves that it is not satisfied, and the procedure in the image processing meams 109 is finished.
Referring again to FIG. 8, the procedure in the image synthesizing means 810 is explained. In the image synthesizing means 810, the synthesis of the image parts processed previously in the image processing means 809 is performed. FIG. 23 shows the flow of the procedure in the image synthesizing means 810.
Referring to FIG. 23, method "ComposeParts" declared at each class data, and method of calculating the magnification of enlarging or reducing each image parts using Position type attributes of each image parts is explained. Use is made of the tree in FIG. 20 which was formed for the sentence (5) in the explanation for the parsing means 807.
First, assuming the number of links included in the tree to be n, the links are given number 1 to n (Step 2301). In the case of FIG. 20, where the number of links included in the tree is 2, n=2, so that the link connecting the node "room" and node "table" is denoted by the first link, and the link connecting the node "table" and the node "apple" by the second link.
Next, putting i=1 (Step 2302), the method "ComposeParts" which is described in the class data of upper node of the i-th link is called out (Step 2303). In the present cuse, the method Compose Parts described in "room" or the class data of upper node of the first link is called out. And, the relation same as that given to the first link is selected from the Relation in the method "ComposeParts" (Step 2304). As, in FIG. 20, the relation given to the first link of the tree is "in", the same relation is selected from the Relation of method "ComposeParts" of "room". Now, it is inspected whether the condition of class is described in the selected Relation (Step 2305), and, if it is done, the class coinciding with the lower node of the i-th link or the upper class is selected from the "Class" (Step 2306), to be proceeded to Step 2307. If it is not, Class default is selected to proceed to Step 2308. In case of Relation "in" of the method "ComposeParts" of "room" , inspection of the description of Class coinciding with "table" or its upper concept shows existence of the description in the third term, so that it is selected.
Lastly, the image part of lower rank is put at the position in the image part of upper node of the i-th link as appointed by the class seleted at Step 2306 (Step 2307, 2308). In the Class default selected now by the position of "table" with reference to "room" is appointed to be P-- in, so that the image part of "table" is placed at the P-- in position of the image part of "room".
Now, as i<n (Step 2309), i is increased by one (i.e. i=2) (Step 2310), and, returning to Step 2303, the similar procedure is applied, that is, the image part of "apple" is arranged with reference to the image part of "table". When it is finished, i<n is judged (Step 2309) to be found not satisfied, and the procedure in the image synthesizing means 810 ends.
Last of all, the image synthesized in the image synthesizing means 810 is displayed by the image displaying means 811, to finish the all procedure of the image editing apparatus according to the present invention.
The above described image retrieving means 805, image processing means 809, and image synthesizing means 810 are collectively named the image editing means.
For referring data necessary for the retrieving, processing and synthesizing in the image editing apparatus, use is not made of the data stored in the image data storing-managing means 805, but is made of the data stored in the image editing data storing means 812. The intention is to make rapid data reference, even if the stored information in the image data storing-managing-means 805 becomes tremendously large.
The image editing apparatus according to the present invention makes it possible, in "case where the object representing the background is omitted" in the sentence being input, to supplement by the language parsing means 807, FIG. 24 shows in the flowchart form the above procedure together with the procedure in the language parsing means 807 shown in FIG. 18. In the following, referring to FIG. 24, the procedure to supplement is explained on a sentence:
"There are an apple and orange on the table"               (6)
First, in the language parsing means 807, the following two basic relation lists are drawn out from the sentence (6) by use of parsing (Step 2401, 2402).
(table on apple)
(table on orange)
Then, the basic tree is formed by the parsing means 807 (FIG. 25) from the basic relation list modified previously, and the tree is obtained.(Step 2403) (FIG. 26).
Now, since the image part expressing the root node thus formed is the base to determine the position of the image parts of other nodes in the image synthesizing means 810, the object of the root node must be the one which expresses the background object. In the image editing apparatus according to the present invention, DefaultBG type variable defanlt-- bg (1011) which distinguishes, whether the class expessed by the class data is the background object or the foreground object is described in the class data, and, with the variable, it is made possible to judge whether the object of the root node is the background object or not, and, if it is not, to add further to the tree the node to express the background object.
Following are the details of the method therefor. First, it is inspected, in class data coresponding to the root node of the tree formed in the language parsing means 807, whether the "DefaultBG" type variable is declared or not (Step 2404). If it is not, the root node expressing the background object, the tree as it is transferred to the image editing data storing means 812 (Step 2406). If it is declared, the root node being found to express the foreground object, a node to express the background object is to be added to the tree as a root node. The addition of the node expressing the background object is made referring the initial value given to the "DefaultBG" type variable default-- bg (1011) of the calss data corresponding to the root node of the tree. That is, the first term of the default-- bg is assigned to the upper node of the root node, and the second term is given to the link which connects the above two nodes (Step 2405).
Application of the above procedure to the tree of FIG. 26. made from the sentence (6) is as follows. First, the object of the root node of the tree is found to be "table". As the class data "table" in FIG. 10 describes
(DefanltBG (default-- bg (C#room in))),
showing that "table expresses an foreground object, the tree in FIG. 26 must be supplemented by a node which is to be a background object. Since, in class data "Table", the background object and the position of "table" is appointed "in" of "room" by default-- bg, "room" is added to the tree in FIG. 26 as the upper node of the root node and positional relation "in" is added to the link connecting the above two nodes. Thus, an input sentence with the background object omitted can be supplenmented.
According to the present invention, by inputting the contents of the intended image by natural language, procedure to edit the image is carried out all automatically, so that the image editing, which required much labor, can be finished in a short time. Also, as the input is made by natural language, no special input apparatus as mouse other keyboard is necessary and anybody can easily edit an image. Further, if the image automatically synthesized with the input of natural language needs another editing later, it is possible to quickly exchange the object forming the synthesized image with other image part, since the image parts related to the image editing are all once retrieved and stored.
