Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is based upon and claims the benefit of priority from prior Japanese Patent Applications No. 2012-078949, filed Mar. 30, 2012; and No. 2013-039817, filed Feb. 28, 2013, the entire contents of all of which, are incorporated herein by reference. 
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an SNS (social network service) system which performs an image processing. 
     2. Description of the Related Art 
     In recent years, a members-only communication service (social network system, hereinafter referred to as SNS) has been gaining in popularity. In general, the SNS system is constructed not by a tree structure but by a semi-lattice structure. In the semi-lattice structure, unlike a tree structure in which all lower-level sets are included in an upper-level set, a structural element of one set is included in a plurality of lower-level sets, and sets with interlaced inclusive relations are constituted. 
     In the SNS system, there is a concept of “friends” (see, e.g. Jpn. Pat. Appln. KOKAI Publication No. 2006-309660), and “friends” are one of sets. 
     For example,  FIG. 1  illustrates a friend network in a case where attention is paid to member “A”. Member “B” (hereinafter the word “member” is omitted, and simply “A”, “B”, . . . , are referred to), “C” and “D” have a friendship, “B1” and “B2” have a friendship with “B”, and “B11” and “B12” have a friendship with “B1”. Further, “D1” has a friendship with “D”, and “D11” and “D12” have a friendship with “D1”. 
     As indicated by “r1” in  FIG. 1 , there may be a case in which friend “D12” of friend “D1” of “D”, that is a friend of “A”, has a friendship with “A”. 
     In the meantime, in such an SNS, there are many cases in which members show photos, which are stored on a server, to each other (see, e.g. Jpn. Pat. Appln. KOKAI Publication No. 2008-242639). 
     In the description below, a member uploads a photo to a server, and the photo itself, which is made public on the Internet as such, or an image, which is created by subjecting the photo to image processing and is made public on the Internet, is referred to as “work”. 
     A member prepares, in his/her own home page (also referred to as “my page”), a top screen having his/her own top image. The top screen is a so-called home screen. 
     In the SNS system, a picture conversion service for image data is provided as an image processing. Thus, there are many members who adopt images which are created by subjecting the top images to the picture conversion. There are many types of picture conversion, such as an oil painting, thick oil painting, gothic oil painting, fauvist oil painting, water color painting, gouache painting, pastel painting, color pencil sketch, pointillism, silkscreen, drawing, and air brush. For example, if a color pencil sketch type is used for picture conversion of a member&#39;s own top image, it is highly possible that this member likes the type of color pencil sketch tone, and it can be supposed that this member will have a friendship with a member who likewise adopts the color pencil sketch tone for picture conversion of the top image, and it is considered that these members will make a group. 
       FIG. 2  illustrates an example in which members, including members who have no friendship, are grouped. Symbol “g1” denotes a group which is a set having a predetermined objective. The group “g1” includes members, such as “A” and “F”, who have no friendship. 
     Jpn. Pat. Appln. KOKAI Publication No. 2006-99753, discloses a grouping technique in the SNS. Jpn. Pat. Appln. KOKAI Publication No. 2006-99753 provides a grouping method of names and keywords, which is characterized by including a step of accepting an input from an input module of names and keywords, a step of producing a cooccurrence matrix of the input names and keywords, and a step of clustering the names and keywords in the produced cooccurrence matrix. 
     In the prior art, however, an SNS relating to a picture conversion technology and a technique relating to such an SNS have not been proposed. In Jpn. Pat. Appln. KOKAI Publication No. 2006-99753, based on a personal name or company name, a product name, a document name, etc., that is, based on text data, grouping is executed by language processing or syntax analysis. In Jpn. Pat. Appln. KOKAI Publication No. 2006-99753, there is no concept of executing grouping based on image data. Thus, in the actual situation, it has not been practiced to increase an interest by merging a picture conversion technology into an SNS or, conversely, by merging an SNS into a picture conversion technology. 
     BRIEF SUMMARY OF THE INVENTION 
     The present invention has been made in consideration of the above-described situation, and the object of the invention is to provide a social network service system which can increase an interest by merging an image processing technology into the SNS, an image display method, and a computer-readable storage medium. 
     According to the present invention, a social network service system includes a server wherein a terminal of a member is connectable to the server. The server includes a memory configured to store a home screen including top image data for each member, a selector configured to select a type of an image processing, and a processor configured to process, at a predetermined timing, the top image data of a member in accordance with the type of the image processing which is selected by the selector. According to the present invention, an interest can be increased by merging an image processing technology into an SNS, or by merging an SNS into an image processing technology. 
     Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instrumentalities and combinations particularly pointed out hereinafter.

     DETAILED DESCRIPTION OF THE INVENTION 
     Embodiments of the present invention will now be described with reference to the accompanying drawings. The embodiments provide an image processing service to increase an interest. An example of the image processing service includes a picture conversion service. The picture conversion service includes many types of picture conversion. One type of the picture conversion includes changing a tone of an original image. 
       FIG. 3  is a block diagram illustrating a main part of the structure of a server  11  which realizes an SNS site  10 . The server  11  includes a member area  100 , a common area  200  and a control area  300 . 
     As illustrated in detail in  FIG. 4 , the member area  100  is an area which is provided for each registered member, and stores a member ID  102  for identifying the member, and various member attribute information  104  of each member in association with the member ID  102 . 
     The member attribute information  104  includes, for example, as shown in  FIG. 5 , a name  104 A, a handle name  104 B, a gender  104 C, an age  104 D, a region  104 E, a member type  104 F, and, as other member unique information, a top screen type  104 G, a number of times of conversion and type of conversion  104 H, a number of times of browsing and type of browsed works  104 I, a friend list  140 J, a group list  104 K, and others  104 L. The member type  104 F is a free member who is simply registered for free, a paid member who is registered with payment, or a premium member who paid a special membership fee. 
     In the a number of times of conversion and type of conversion  104 H, the type of picture tone selected when the member executed picture conversion and the number of times of picture conversion are recorded. The type of picture tone, which has most frequently been selected by the member, is stored in  104 H 1 . In addition, in the number of times of browsing and type of browsed works  104 I, the type of picture tone, which has most frequently been browsed by the member among published works, and the number of times of browsing are recorded. The type of picture tone, which has most frequently been browsed by the member, is stored in  104 I 1 . 
     In the friend list  140 J, the ID of a friend member (friend) of the present member, is stored. In the group list  104 K, a classified group name, to which the present member belongs, is stored. The group name is a name of a group of each type of picture conversion tone, such as oil painting, water color painting, pastel painting, etc. The group is not limited to the type of picture conversion. For example, the group may be a group of members who use picture-converted images as the top images P 2 , or a group of members who do not use picture-converted images as the top images P 2 . The group is a set of members who have a predetermined common item and are logically connected on the network. 
     In addition, the member area  100  ( FIG. 4 ) includes an upload image buffer area  106  in which image data of photos uploaded by the member is stored; a work buffer area  108  in which picture-tone images (works), which have been picture-converted in the SNS site  10 , are stored; a download work buffer area  110  which downloads and stores works of other members; a top screen storage area  111  in which the top screen P 1  is stored (the area  111  includes a top image storage area  112  in which the top image P 2  is stored, and a profile storage area  114  in which a profile P 3  of the member is stored); a friend list area  116  in which member IDs of members, who are friends of the present member, are stored; and a top-screens-for-friends area  118  in which the top screens P 1  of the present member, which are displayed on the terminals of the friends stored in the friend list area  116 , are stored (area  118  includes an N-number of areas  118   1  to  118   N  divided for respective friends). 
     The common area  200  in  FIG. 3  is an area which is provided common to all members. The common area  200  includes a work area  202  in which many works, which were created by converting images uploaded by members to picture tones, are stored. 
     Each of works stored in the work area  202  includes image data  208 , an image ID  204  for identifying the work, and image attribute information  206  indicative of the attribute of each image. 
     As shown in  FIG. 6 , the image attribute information  206  includes a member ID  206 A indicative of the poster of the work; date information  206 B of, e.g. a date of creation or a date of posting; image type information  206 C such as a size of image data and type of picture tone; browse request number (access number) information  206 D indicative of the number of times of browsing of the work; download number information  206 E indicative of the number of times of download of the work; point information  206 F indicative of the evaluation of the work; tag information  206 G for attaching a tag indicating what the work relates to, such as a person, nature, flower, morning glory, etc.; grouping information  206 H indicative of a group if the work belongs to the group; and other information  206 I which is unique to the work. These information items are stored together with the image ID  204  and image data  208 . 
     From the member ID  206 A, the creator of the work is understood, and it can be determined whether the creator is a free member, a paid member or a premium member. In addition, from the tag information  206 G, the work can be categorized. Furthermore, from the grouping information  206 H, the work can be grouped. 
     The control area  300  shown in  FIG. 3  includes a picture conversion processor  302 , a parameter table  304 , a display controller  308 , an evaluation controller  310 , a member management module  312 , and a grouping controller  314 . 
     The picture conversion processor  302  executes a picture conversion process for changing a tone of image data, which is stored in the upload image buffer area  106 , to a picture-tone. The parameter table  304  stores parameters for picture conversion, which are referred to when the picture conversion process is executed. The display controller  308  stores a control program for displaying the work on the screen. 
     The evaluation controller  310  evaluates the works, which are stored in the work buffer area  108  of the member area  100 , in accordance with the number of times of access, and gives points to each work. The member management module  312  manages the members by the member IDs, and controls respective services for the free member, paid member and premium member. The member management module  312  also controls the SNS function of the SNS site  10 . The grouping controller  314  executes a process of grouping members, as will be described later with reference to  FIG. 9 . 
     In addition, the server  11  is provided with a CPU  20  and a display buffer  30 . The CPU  20  controls the entirety of the server  11 , based on various control programs stored in the control area  300 , and executes various processes which are necessary for displaying many works in a table format on the Internet. Besides, the CPU  20  includes a graphic accelerator  22  for executing a high-level graphic process. By the graphic accelerator  22 , images can be categorized and displayed, as will be described later, by simply designating some conditions from driver software. In the meantime, the above-described driver software is, for example, a publicly known open GL with a high general-purpose applicability and an extension library for using the open GL. 
     The display buffer  30  is a working memory for developing images for display, when the CPU  20  displays many works in a table format. 
     Next, concrete operations of the image display system of the present embodiment will be described with reference to flowcharts. 
     To begin with, referring to  FIG. 7 , a top screen creation flow, which is executed by the server  11 , is described. Although not illustrated, a member terminal of the SNS is connected to the server  11  over a network. Responding to a request from the member terminal, the server  11  creates a top screen P 1  of the present member (step S 102 ). In addition, the server  11  accepts upload of an image (photo) from the member terminal and stores the image (photo) in the upload image buffer area  106  (step S 104 ). Further, the server  11  determines the presence/absence of an instruction from the member as to whether the uploaded image is to be used as the top screen P 1  as such or not (step S 106 ). 
     When an instruction (“as such”) to use the image as such has been received from the member, the server  11  prompts the member to select any one of the images of the member, which are stored in the upload image buffer area  106 , as the top image P 2  in accordance with an operation from the member terminal (step S 108 ). Conversely, when an instruction to use a picture-converted image, instead of using the uploaded image as such, has been received from the member, the server  11  prompts the member to select a top image P 2  from the work buffer area  108  which stores picture-tone images (works) which were created by picture-converting the top image P 2  in the SNS site  10  (step S 120 ). Subsequently, the server  11  sets the top image P 2 , which has been selected in step S 108  or step S 120 , in the top screen P 1  (step S 122 ). 
       FIG. 13  illustrates an example of the top screen P 1 . The top screen P 1  is composed of the top image P 2  which is set in a part of the top screen P 1 , and profile contents (character strings) P 3  of the member, such as rank, badge, favorite photo and favorite conversion. In step S 122 , the server  11  executes a process of setting the top image P 2  in the top screen P 1 . Thereafter, as illustrated in  FIG. 14 , the server  11  executes a group update process (step S 124 ), and updates the group into which the present member is classified. 
       FIG. 14  illustrates a state in which members are being grouped in accordance with the type of picture tone of the top image data P 2  of the top screen P 1  of the present member. 
       FIG. 8A  is a flowchart illustrating a process procedure of a top image creation process for each friend. The server  11  reads out the top image P 2  from the top image storage area  112  in the present member&#39;s own member area  100  in response to a request from the member terminal (step S 202 ). 
     Subsequently, the server  11  detects the conversion type, i.e. any one of the above-described oil painting, water color painting, pastel painting, etc., of the top image P 2  which is set in the top screen P 1  of “friend 1” who is the first friend stored in the top-screens-for-friends area  118   1  of the member area  100  (step S 204 ). 
     Thereafter, the server  11  picture-converts the top image P 2  in the top screen P 1  of the present member, which has been read out in step S 202 , by using the conversion type for “friend 1”, which has been detected in step S 204 , and stores the picture-converted image in the area  118   1  of the top-screens-for-friends area  118  (step S 206 ). In addition, the server  11  detects the conversion type of the top image P 2  in the top screen P 1  of “friend 2” (step S 208 ), picture-converts the top image P 2  in the top screen P 1  of the present member, which has been read out in step S 202 , by using the conversion type for “friend 2”, which has been detected in step S 208 , and stores the picture-converted image in the area  118   2  of the top-screens-for-friends area  118  (step S 210 ). Similarly, the server  11  detects the conversion type of the top image P 2  in the top screen P 1  of “friend N” (step S 212 ), picture-converts the top image P 2  in the top screen P 1  of the present member, which has been read out in step S 202 , by using the conversion type for “friend N”, which has been detected in step S 212 , and stores the picture-converted image in the area  118   N  of the top-screens-for-friends area  118  (step S 214 ). 
     Thus, by the execution of the above process illustrated in the flowchart of  FIG. 8A , for example, if the present member is “A”, the top screen P 1  of member “A” including the top image P 2  of member “A”, which has been converted by using the same conversion type as the conversion type of the top image P 2  of each of friends “1” to “N”, is stored in the areas  118   1  to  118   N  of the top-screens-for-friends area  118 . 
       FIG. 8B  is a flowchart illustrating another process procedure of the top image creation process for each friend. The server  11  reads out the top image P 2  from the top image storage area  112  in the present member&#39;s own member area  100  in response to a request from the member terminal (step S 302 ). Subsequently, based on first-rank information  104 H 1  included in the number of times of conversion and type of conversion  104 H in the member attribute information  104  of “friend 1” who is the first friend stored in the top-screens-for-friends area  118   1  of the member area  100 , the server  11  detects the conversion type, i.e. any one of the above-described oil painting, water color painting, pastel painting, etc., which is the conversion type with a largest number of times of conversion (step S 304 ). 
     Thereafter, the server  11  picture-converts the top image P 2  in the top screen P 1  of the present member, which has been read out in step S 302 , by using the conversion type for “friend 1”, which has been detected in step S 304 , and stores the picture-converted image in the area  118   1  of the top-screens-for-friends area  118  (step S 306 ). In addition, the server  11  detects the conversion type with a largest number of times of conversion of “friend 2” (step S 308 ), picture-converts the top image P 2  in the top screen P 1  of the present member, which has been read out in step S 302 , by using the conversion type for “friend 2”, which has been detected in step S 308 , and stores the picture-converted image in the area  1182  of the top-screens-for-friends area  118  (step S 310 ). Similarly, the server  11  detects the conversion type with a largest number of times of conversion of “friend N” (step S 312 ), picture-converts the top image P 2  in the top screen P 1  of the present member, which has been read out in step S 302 , by using the conversion type for “friend N”, which has been detected in step S 312 , and stores the picture-converted image in the area  118 N of the top-screens-for-friends area  118  (step S 314 ). 
     Thus, by the execution of the above process illustrated in the flowchart of  FIG. 8B , for example, if the present member is “A”, the top screen P 1  of member “A” including the top image P 2  of member “A”, which has been converted by using the same conversion type as the conversion type with a largest number of times of conversion of each friend, is stored in the areas  1181  to  118 N of the top-screens-for-friends area  118 . 
       FIG. 9  is a flowchart illustrating a process procedure of a grouping process. The server  11  retrieves member IDs of friends or members in a predetermined range (step S 402 ). Then, the server  11  groups the retrieved member IDs in accordance with each image type indicated by the information stored in the image type information  206 C (step S 404 ). Subsequently, the server  11  updates the group list  104 K in the various member attribute information  104  of each member (step S 406 ). Accordingly, by the execution of the above process illustrated in the flowchart of  FIG. 9 , friends of a certain member or members in a predetermined range are grouped in accordance with image types, such as an oil painting group, a water color painting group, a pastel painting group, etc. Thereafter, the server  11  sends information to the grouped members (step S 408 ). The creator of this information that is to be sent may be any one of the respective members and the administrator of the server  11 . 
     Thus, with the above process illustrated in the flowchart of  FIG. 9  being executed, and with information being sent to the grouped members, the following operations and advantageous effects can be obtained. 
     &lt;Operations&gt; 
     (1) Members are grouped in accordance with each conversion type, which is used on the top screen P 1 , thereby performing sharing of works and friend recommendation. 
     (2) Members are grouped in accordance with each conversion type, which is used on the top screen P 1 , thereby notifying, for example, a water color painting contest if the conversion type is water color painting. 
     (3) Members are grouped in accordance with each conversion type with a large number of times of use by members in the previous day (or previous log-in), in the previous month, etc., thereby performing sharing of works and friend recommendation. 
     (4) In accordance with each conversion type with a large number of times of use by members in the previous day (or previous log-in), in the previous month, etc., a guide of, for example, a water color painting contest is notified if the conversion type is water color painting.
 
(5) Members are grouped in accordance with each conversion type which is registered as a favorite conversion type by members, thereby performing sharing of works and friend recommendation.
 
(6) In accordance with each conversion type which is registered as a favorite conversion type by members, a guide of, for example, a water color painting contest is notified if the conversion type is water color painting.
 
&lt;Advantageous Effects&gt;
 
     As a result, in order to activate communication through converted images and works and to create a community, and to share favorite images, members are internally grouped by the frequently used conversion type or favorite conversion type, and sharing of works and event guides can be notified to each group and communication and creation of communities can be efficiently promoted. 
     In addition, a gallery or categorization according to each conversion type can be realized, and as the number of conversion types is increasing hereafter, members can be efficiently and effectively grouped according to favorites, and communication and communities can be activated. 
       FIG. 10  is a flowchart illustrating the process procedure of an upload/posting process. The server  11  accepts upload of an image (photo) from a member terminal, and stores the image (photo) in the upload image buffer area  106  (step S 501 ). In addition, the server  11  selects the type of picture tone for conversion, in accordance with a selection instruction from the member terminal (step S 502 ). Using the selected type, the server  11  executes picture conversion of the uploaded image (step S 503 ). Then, the server  11  counts the selected type of picture tone, counts up the number of times of this type, and stores the counted number of times in the number of times and type of picture conversion  104 H (step S 504 ). 
     Consequently, since such a case may arise that the content of area  104 H 1  in which the type of picture tone with a largest number of times of selection varies, the content of area  104 H 1  is updated (step S 505 ). In addition, if a new picture tone is selected, the group will also vary and thus the group is updated (step S 506 ). 
     Thereafter, the image, which has been picture-converted in step S 503 , is stored in the work buffer area  108  and is stored in the work area  202  (step S 507 ). In addition, as the image attribute information  206 , the member ID  206 A indicative of the poster of the work and the date information  206 B indicative of, e.g. the date of posting are written (step S 508 ). 
     Accordingly, by the execution of the above process illustrated in the flowchart of  FIG. 10 , in the number of times of conversion and type of conversion  104 H, the content of area  104 H 1 , in which the type of picture tone with a largest number of times of selection varies is stored, is updated, and the number of times and the type are stored. 
       FIG. 11  is a flowchart illustrating the process procedure of a browse process. The server  11  transmits a table-of-works display screen to the member terminal (step S 601 ). In accordance with a selection instruction from the member terminal, the server  11  selects any one of the works from the table-of-works display screen (step S 602 ). Subsequently, the server  11  executes such control that the original image, which is the image before the picture conversion of the selected work, is displayed on the member terminal, and the selected work is downloaded (step S 603 ). Then, the server  11  counts the type of the downloaded picture tone, counts up the number of times of this type, and stores the counted number of times in the number of times of browsing and type of browsed works  104 I (step S 604 ). 
     Consequently, since such a case may arise that the content of area  104 I 1  in which the type of picture tone with a largest number of times of browsing varies, the content of area  104 I 1  is updated (step S 605 ). In addition, if a new work is downloaded, the group will also vary and thus the group is updated (step S 606 ). 
     Accordingly, by the execution of the above process illustrated in the flowchart of  FIG. 11 , in the number of time of browsing and type of browsed works  104 I, the content of  104 I 1 , in which the type of picture tone with a largest number of browsing varies is stored, is updated, and the number of times and the type are stored. 
       FIG. 12  is a flowchart illustrating the process procedure of a top screen update process. The server  11  executes the process illustrated in this flowchart at a predetermined time, for example, once a day at midnight. Specifically, the server  11  reads out information written in the most frequent conversion type  104 H 1 , and checks the first-rank type of picture tone which has been most frequently selected for picture conversion by the present member (step S 701 ). In addition, the server  11  reads out information written in the most frequent browse type  104 I 1 , and checks the first-rank type of picture tone which has been most frequently browsed by the present member (step S 702 ). Next, the server  11  picture-converts the top image data which is the image data representative of the top image P 2 , by using the most frequent type of picture tone (step S 703 ). The most frequent type, in this context, refers to the type of picture conversion, which corresponds to the greater of the number of times checked in step S 701  and the number of times checked in step S 702 . 
     In the present embodiment, the type of picture tone for conversion is determined by using both the number of times of picture conversion with respect to each type, and the number of times of browsing with respect to each type. Alternatively, the type of picture tone for conversion may be determined by using only the number of times of picture conversion with respect to each type or only the number of times of browsing with respect to each type. 
     Thereafter, the top image P 2 , which is represented by the top image data, is set in the top screen P 1  (step S 704 ). Therefore, according to the present embodiment, the top image P 2  of the top screen P 1  of the member himself/herself is automatically picture-converted by the type of picture conversion that was used by the member himself/herself (the type stored in  104 H 1 ) or by the type of picture conversion that was browsed by the member himself/herself (the type stored in  104 I 1 ). Specifically, as illustrated in  FIG. 13 , the top image P 2  of the top screen P 1  of the member himself/herself is automatically picture-converted to pastel painting, pencil sketch or oil painting. Thus, an interest can be increased by merging a picture conversion technology into an SNS or by merging an SNS into a picture conversion technology. 
     In the meantime, in general, an SNS functions among closed members, but such a configuration may be adopted that general users, who are not registered as members, can browse works. 
     &lt;Advantageous Effect of the Embodiment&gt; 
     According to the present embodiment, since the top image data of a member is automatically converted to a picture-tone image data which suits the member&#39;s taste, such an advantage can be obtained that an interest does not decrease for both the member himself/herself and friends. 
     According to the present embodiment, members, who use the same type of picture conversion as the picture tone of the top image data of the present member, can be grouped, such an advantage can be obtained that the present member is easily associated with members having the same taste. In addition, such an advantage can be obtained that events, for instance, which are suited to the members of the group, can easily be notified to these members. 
       FIG. 15  is a block diagram illustrating the whole structure of the SNS system according to the present embodiment. 
     The SNS site  10  including the server  11  is connected to terminals  1 - 1 ,  1 - 2 ,  1 - 3 , . . . , of members via the Internet  500 . The terminals  1 - 1 ,  1 - 2 ,  1 - 3 , . . . , are, for instance, smartphones or personal computers. In addition, numerals  2 - 1 ,  2 - 2 ,  2 - 3 , . . . , denote wristwatch-type wrist terminals which are, when used, attached to the arms, and the wrist terminals  2 - 1 ,  2 - 2 ,  2 - 3 , . . . , are wirelessly connected to the terminals  1 - 1 ,  1 - 2 ,  1 - 3 , . . . . 
     The relationship between the terminal  1 - 1  and wrist terminal  2 - 1  is described. As illustrated in  FIG. 16A , the terminal  1 - 1  and wrist terminal  2 - 1  are wirelessly connected by, e.g. Bluetooth (trademark), and data can be exchanged between the terminal  1 - 1  and wrist terminal  2 - 1 .  FIG. 16B  illustrates a state in which a profile screen P 1  including a profile image P 2 , which is the top image, is displayed on a display section  31  of the smartphone-type terminal  1 - 1 .  FIG. 16C  illustrates a state in which a profile image P 2  is displayed on a display section  40  of the wrist terminal  2 - 1 . 
     At this time, the display area of the display section  31  of the smartphone-type terminal  1 - 1  is different from the display area of the display section  40  of the wrist terminal  2 - 1 , and the display area of the display section  40  of the wrist terminal  2 - 1  is much smaller than the display area of the display section  31  of the smartphone-type terminal  1 - 1 . Thus, as is understood from the comparison between the display state of  FIG. 16B  and the display state of  FIG. 16C , the display section  31  of the smartphone-type terminal  1 - 1  is caused to display the entirety of the profile screen P 1  that is the home screen, but the display area of the display section  40  of the wrist terminal  2 - 1  is caused to display only a main part, i.e. about ⅔ of an upper part, of the profile screen P 1  including the profile image P 2 . 
     According to this display mode, on the display section  40  of the wrist terminal  2 - 1  which has a small display area, the profile image P 2  can be clearly displayed, without being extremely reduced in size, and the profile screen P 1  can be displayed. 
     Needless to say, in the wrist terminal  2 - 1 , if a scroll operation is performed, a lower part of the profile screen P 1 , which is not displayed in  FIG. 16C , can be displayed. 
       FIG. 17A  and  FIG. 17B  illustrate states in which the terminal  1 - 1  and wrist terminal  2 - 1  are used. In  FIG. 17A , member “A” possesses the terminal  1 - 1  and connects the terminal  1 - 1  to the SNS site  10  via a mobile phone network or the Internet, and also possesses the wrist terminal  2 - 1  and receives part of information, such as profile information of friend members or e-mails, by the wrist terminal  2 - 1 . 
     According to this mode of use, even if the wrist terminal  2 - 1  does not have a function of connection to the Internet  500 , the wrist terminal  2 - 1  can receive, for example, profile information of friend members, e-mails, etc. 
     In the example illustrated in  FIG. 17B , when member “B” possesses the terminal  1 - 1  and member “C”, who does not possesses the terminal  101 , possesses the wrist terminal  2 - 1 , if member “B” and member “C” come close to each other, data exchange is enabled between the terminal  1 - 1  of member “B” and the wrist terminal  2 - 1  of member “C”. 
     According to this mode of use, even if member “C” does not possess the terminal  1 - 1  which has the function of connection to the Internet  500 , member “C” can obtain information which is acquired via the Internet  500 . 
     Next, display examples of the wrist terminal  2 - 1  are described. Usually, as illustrated in  FIG. 18A , the wrist terminal  2 - 1  executes time display P 4  including the present year/month/day, a day of the week, and hour/minute. By switching the display mode, the wrist terminal  2 - 1  displays, as illustrated in  FIG. 18B , the profile screen P 1  of the present member himself/herself or a friend member. By detecting that a friend member has come near, the profile of the friend member may automatically be displayed. 
     Even with this wrist terminal  2 - 1 , a work, which is image data converted to a picture tone, can be browsed, and the number of times of browsing on the wrist terminal  2 - 1  is included in the above-described number of times of browsing. 
     Thereby, even if a member puts the terminal in a bag or the like, if the member wears a wrist terminal as a wristwatch, the member can easily confirm the profile or profile image of the member himself/herself or a friend member, or browse the work. In addition, when the picture tone of the profile screen of the friend member has been changed, a notification can be received or the profile image of the friend member can be automatically displayed. 
     Although the embodiments of the invention have been described, the present invention is not limited to these embodiments. The present invention includes inventions disclosed in patent claims and the scope of equivalents thereof. The picture conversion service is explained as an example of the image processing service and the tone change is explained as an example of the picture conversion. The picture conversion may include other types of conversion. For example, the type of the picture conversion may include a conversion of a facial picture to a portrait painting, a conversion of a still picture to a moving picture, a conversion of a two-dimensional image to a three-dimensional image. The type of picture conversion may include a conversion to a smiling face image, a conversion to a crying face, and a conversion to an angry face, a conversion to a moving picture with a different frame rate, time, and a moving speed, or the like. 
     &lt;Advantageous Effect of the Embodiment&gt; 
     According to the present embodiment, the profile screen which displays the profile of a member can be changed, on a friend-by-friend basis, to a screen which is converted to a picture-tone image that suits the taste of each friend. Specifically, such an advantage is obtained that different profile images of the same member can be viewed from respective friends.
