In order to achieve the above object, the posted image evaluation method according to the sixth invention publishes posted images on the display unit, accepts comments from others on the posted images, analyzes the contents of the comments, and analyzes The priority of the image is determined from the comment made.

In order to achieve the above object, a program according to a seventh invention includes a step of posting a posted image on a display unit on a computer of a posted image evaluation device, a step of receiving a comment from another person on the posted image, The step of analyzing the content of the comment and the step of determining the priority of the image from the analyzed comment are executed.

According to the present invention, it is possible to provide a posted image evaluation device, a posted image evaluation method, a program, and a corresponding image display device that evaluate posted images based on comments of others.

A preferred embodiment will be described below using an image evaluation system to which the present invention is applied according to the drawings. In the description of the present embodiment, first, a scene where a blog is created will be described. FIG. 1 is a block diagram showing the entire image evaluation system. A user transfers and records image data of an image 25 from a captured image recorded in the memory of the camera 10 to a PC 32. The image data of the image 25 is recorded in the recording unit of the PC 32 and displayed on the screen 32a. The user inputs individual text on the PC 32 while viewing the screen 32a. The text is recorded in the recording unit in association with the image. Then, a blog composed of a combination of images and text is transferred from the PC 32 via the network 35 to the site server 51 that functions as a blog site server (posted image evaluation device).

A site server 51 of a site (company) that operates a blog is connected to a PC 32 or the like via a network 35, and includes a recording unit 52, a resizing unit 53, a user determining unit 54, a portable transmitting / receiving unit 55, a time determining unit 56, and an association. Section 57, text determination section 58, display control section 59, database 58a, priority determination section 60, keyword creation section 61, CPU 63 and ROM 64.

The recording unit 52 records blog data including images and text transmitted from the user and comments on the images. The resizing unit 53 reduces the data amount and creates reduced image data so that the recorded image can be easily sent to the mobile phones 36a and 36b. The user determination unit 54 determines the user name of the connected PC 32 and the user names of the mobile phones 36a and 36b and the PC 34 that have accessed the posted blog.

The portable transmission / reception unit 55 controls transmission / reception of comments and image data between the cellular phones 36 a and 36 b that have requested browsing and the site server 51. The time determination unit 56 determines the shooting date and time of the captured image, and determines the order of display. The associating unit 57 associates data such as the shooting date and time and the shooting position with the image. The text determination unit 58 analyzes comments (impressions and criticisms) on the received images in order to evaluate the images and determine priorities. The database 58a is a database used when the text determination unit 58 performs text analysis, and details thereof will be described later with reference to FIG.

The priority determination unit 60 evaluates the image according to the analysis content of the comment (text) attached to the image, and determines the priority. Details will be described later with reference to FIG. The display control unit 59 performs display control of the image according to the set priority, and assigns a keyword to the image. The keyword creation unit 61 creates a keyword from the comment. For example, if “This is a picture taken at Yatsugatake, beautiful” is described as a comment, “Yatsugatake” is extracted as a keyword from this comment.

The CPU 63 reads a control program stored in the ROM 64 and controls the entire site server 51. The site server 51 also cooperates with the carrier server 41 operated by the carrier company of the mobile phones 36a and 36b. The image recorded in the recording unit 52 of the site server 51 is converted into reduced image data by the resizing unit 53, and the reduced image data is converted into the portable transmission / reception unit 55 and the carrier server according to the result of the user determination unit 54. 41 to the mobile phones 36a and 36b.

The user of the mobile phone 36a, 36b sees the image sent from the site server 51 and returns a comment by e-mail. At that time, the text determination unit 58 analyzes only the portion (text data) related to the reply mail image. The text determination unit 58 uses the database unit 58a for the text data recorded in the recording unit 52 to extract and analyze words related to the image. In this way, the priority determination unit 60 analyzes comments (text) received from various directions, evaluates the images, determines priorities, and objectively determines whether the images are important. Judge in a close way. The display control unit 59 selects the display method and order according to the analysis content of the text sent to the image. Moreover, a keyword is given to the image as needed.

In addition, as described above, the comment regarding the image is recorded in the recording unit 52. When the comment is displayed together with the image recorded in the recording unit 52, depending on the determination result of the text determination unit 58, the comment is appropriately selected. Comments may be shortened. The screen 33 is an example of this blog display, and the received comments 37c are displayed side by side with the image. This blog display can be viewed on the PC 34 connected to the network 35, the mobile phones 36a, 36b, and the like. Further, when displaying a blog, the weighting of the determination may be changed in consideration of what user the mobile phones 36a, 36b belong to. The carriers of the mobile phones 36a and 36b may supplement information such as user profiles in cooperation with the site server 51. Further, what is determined as a good image by analyzing the comment may be displayed in a large size as in the screen 38.

In addition, as a method of using prioritized images, for example, when newly creating a blog or SNS (Social Networking Service), as shown in FIG. When writing or reading, a past image selected in the auxiliary screen 33a may be displayed. The image displayed on the auxiliary screen 33a is an image having a high priority in the past, and is returned from the site server 51 to the photographer's PC. The flow at this time will be described later with reference to FIG.

Next, the flow of the site server 51 functioning as a blog site will be described using the control flowchart shown in FIG. The following processing is executed by the recording unit 52 and the like with the CPU 63 as the center. First, a plurality of images recorded in the recording unit 52 of the site server 51 are posted so as to be viewable by the display control unit 59 (S11). A period for accepting comments from others for a predetermined period is provided for these images (S12, S13). A comment may be accepted for each image, or a plurality of images may be received as a set.

The input comment is transmitted from the mobile phones 36a and 36b to the site server 51, and the recording unit 52 stores the comment (text) related to the image input via the mobile transmission / reception unit 55 (S12). The comments can be received not only from the mobile phones 36a and 36b but also from a third party PC 34. When a predetermined period (for example, one week) elapses (S13, YES), the received comment is analyzed, and the expression part related to the greeting and the recent condition report is deleted from the comment, and the part related to the image is determined and extracted. (S14).

The comment analysis in step S14 is executed by the text determination unit 58, and the database 58a shown in FIG. The database 58a is a database 58a for extracting words from text, and stores nouns that are likely to be related to images, subsequent particles, and words suitable for describing images.

When entering the comment analysis subroutine of step S14 shown in FIG. 4, first, it is determined from the word combination of the comment (text) related to the image stored in the recording unit 52 what is the topic in the text. (S21). When it relates to an image, the image-related nouns as shown in FIG. 5, for example, “photograph”, “composition”, “color”, and the like are applicable.

At that time, referring to particles as appropriate, for example, if “ga” of “photograph” and “ha” of “color is” are taken into consideration (S22), image-related matters may become even more topical. It becomes clear that the words that follow are narrowed down to the words that describe them. Based on this concept, it is determined from the database whether the predetermined sentence of the comment is an image-related topic (S23) and whether it is affirmative or negative (S24). The sentence delimiter may be determined by “.” Or “.”.

If there is the word “beautiful” in the comment and you cancel it before or after that, it becomes a negative expression such as “color is not beautiful”, so whether there is a negative expression Is determined in steps S25 and S30 to finally determine whether the result is affirmative or negative. Thereafter, it is determined with reference to the database 58a whether or not an adjective expression such as "very" or "very" is composed of adjectives and adjective verbs (S26, S31). If there is such emphasis (S27 YES, S32 YES), processing (S28, 33) is performed so that the number of comments is doubled. In this way, for each recorded comment, in steps S28, S29, S33, and S34, it is analyzed and determined whether it is positive or negative, and whether it is strong or weak.

Returning to step S15 in FIG. 3, the keyword creating unit 61 creates a keyword from the comment and assigns it to the image. When assigning a keyword, a keyword may be assigned to an image using a narrowed word from a narrowed sentence in a comment analysis subroutine. For example, if the keyword is created as a comment, “This is a picture taken at Yatsugatake. Beautiful.”, “Yatsugatake” is extracted as a keyword. Further, the comment may be shortened and displayed by using the result of the comment analysis.

When keyword creation is completed, priority is next determined (S16). This priority determination is executed by the priority determination unit 60 according to a subroutine shown in FIG. When this subroutine is started, the number N of comments received is determined for each image (S41). As a result of the determination in this step, an image without a comment branches to step S57, and the priority is the lowest (priority 0) (S42). The fact that there is no comment does not attract the viewer of the image, so the priority is set to zero.

As a result of the determination, if a comment exists, the process proceeds to step S43. In the comment analysis in step S14, the number Na of positive comments Ca and the number Nd of negative comments Cd are respectively determined (S43, S44). Next, it is determined whether or not the number N of comments is greater than a predetermined number M (S45). When the number N of comments is larger than the predetermined value M, many viewers pay attention and the reliability of the evaluation becomes high. However, when the number N is smaller than the predetermined value M, the degree of attention and reliability are not so high. Since there is no value, it is set as an intermediate evaluation value. In other words, even if there are some comments that are not gathered over the predetermined value M, if there are some comments, the evaluation is intermediate between a very high evaluation and a very low evaluation.

When the comment number N is less than the predetermined value M, the priority is assigned according to the magnitude relationship between the positive comment number Na and the negative comment number Nd. In step S46, the number of positive comments Na and the number of negative comments Nd are compared, and when there are many positive comments, the priority is set to 3 (S47). On the other hand, when there are many negative comments as a result of the comparison, the priority is set to 2 (S48).

In step S45, if the number of comments N is greater than the predetermined number M as a result of the determination, it can be said that there is a response to the image in both good and bad meanings. In this case, in step S51 and subsequent steps, priority classification is performed as follows.
When there is no negative comment Cd and there is a positive comment Ca, the highest priority is determined and the priority is set to 5 (steps S45 → S51 → S52).
If there is even a small positive comment Ca, even if there is a negative comment Cd, the priority is increased and the priority is set to 4 (steps S45 → S53 → S54).
If there is no positive comment Ca and there is no negative comment Cd, the priority is not the lowest and the priority is set to 1 (steps S45 → S55 → S56).
If there are many comments and only negative comments Cd, the priority is set to the lowest and the priority is set to 0 (steps S45 → S55 → S57).

When the priority determination is completed, the process proceeds to step S17 in FIG. 3, and the display control unit 59 selects and displays an image with a high priority. Those with higher priority are displayed with priority, and are displayed with a larger size.

As described above, in the embodiment of the present invention, since the priority is determined based on the text data of the comment, everyone wants to see from a large number of images in descending order of user evaluation. Images can be displayed in the order of images, or images with a high evaluation can be displayed in a large size. It may also be used to determine priorities when storing images.

Next, an example in which an image whose priority is determined using FIGS. 7 and 8 is used in an image display device such as a personal computer or a camera will be described. In addition to the image transmission from the camera 10 as described above, when the camera 10 or the PC 32 to which the camera 10 is connected is connected to the network 35, the image of the image that has been well-received by others and has been preferentially selected on the site. Data may be recorded with keywords in a predetermined area in the camera.

FIG. 7 is a flowchart relating to processing for transmitting a high-priority image, priority data, comments, keywords, and the like from the site server 51 to the image photographer or the PC or camera of the other person. The priority is 4 or more, for example, but this setting can be arbitrarily changed. 7A shows the operation on the site server 51 side, and FIG. 7B shows the operation on the camera 10 side.

When the flow of transmission of priority data to the site camera of FIG. 7A is entered, it is first determined whether or not there is a transmission request from the camera 10 or the PC 32 or 34 (S61). This is determined by whether the camera 10 or the PC 32 or 34 connected to the camera 10 transmits a connection signal to the site server 51 (S71), and the site server 51 receives this transmission signal. The camera 10 or the PC 32 is specified by any user by the user determination unit 54.

When a connection signal is transmitted from the camera 10 or the like, the process proceeds to step S62, and it is determined whether there is an image with a high priority among the images taken by the user determined by the priority determination unit 60. (S62). If the result of determination is that there is no image with high priority, this routine is terminated. If there is an image with high priority, the routine proceeds to step S63, where an image with high priority is selected. Then, a comment, a keyword or the like regarding this image is transmitted to the camera 10 of the user (S63).

When a control unit (CPU) built in the camera 10 receives a high priority image or the like (S72), a comment, a keyword (priority data), or the like is recorded in the storage unit of the camera 10 in association with the image. (S73). An image or the like recorded in the memory is displayed on the display unit of the camera 10 and is referred to when shooting by the user. These data may be recorded by the PC 32 or the PC 34 instead of the camera 10.

As described above, according to the flow shown in FIG. 7, an image with high priority can be viewed efficiently. Further, if it is displayed at the time of shooting, it can be used as a reference for determining the shooting angle of view. Here, in order to expand the usability of the image, the provision of the image is permitted to others other than the photographer.

Next, with reference to FIG. 8, as an example of the use form of the transmitted data, use when creating a blog by the image display device (camera or PC 32) will be described. The PC 32 will be described as a representative. The CPU (control unit) of the PC 32 executes the following processing. When the PC blog creation processing routine is entered, first, when creating a blog, an image taken in the same season as last year is searched (S81). If there is an image with a high priority from among these images, S82 is branched to Y and an image with a high priority is displayed on the sub-screen as shown in FIG. 2 (S83). If keywords are also entered, it will be easier to sort and search. Of course, the comment can be displayed and can be enjoyed together with the image.

As described above, in the embodiment shown in FIGS. 7 and 8, since the image recorded in the camera is an excellent image carefully selected from comments written by many people, it is stored in the camera or the PC and occasionally stored. It is worth keeping it for viewing. In addition, a large number of images taken in the past cannot be viewed all at once. However, as shown in this embodiment, if priority is given and images with a high priority are displayed, the past It is possible to taste memories appropriately without wasting images.

In the example of the above embodiment, the form of the user's image posting has been described with a blog, but the present invention is not limited to this. For example, it may be a bulletin board that displays only images, and the browsing target is not limited to an unspecified large number like a normal blog, but limited to allow browsing to a specific group. There may be something. In addition, a blog does not necessarily require both images and text, and can be established with only one of them.

In the above embodiment, it has been described that each process of the site server 51 is performed by the CPU 63, the recording unit 52, the resizing unit 53, and the like, but the present invention is not limited to this mode. In other words, the functions of the user determination unit 54, the association unit 57, the text determination unit 58, the priority determination unit 60, the keyword creation unit 61, and the like may be replaced with software processing instead of hardware, instead of part of the functions. It is. Specifically, each of the functional units described above is replaced with a processing function executed by the CPU 63. In this case, the program stored in the ROM 64 and causing the CPU 63 to execute these processing functions constitutes the present invention. In addition, it can be said that a recording medium for storing the program also constitutes the present invention. Such a program may be stored not only in the ROM 64 but also supplied from the outside via another network such as a CD.

As described above, in the system of the present embodiment, based on the comments received on the image, whether the image is good or bad to see objectively, is it worth sharing with everyone, Further, it is possible to provide a system that determines whether or not it is meaningful to touch and appreciate and performs display control according to it. In the future, as memories increase in capacity and digital cameras become more widespread and easier to use, important images will not be lost or forgotten from the increasing volume of images. It is possible to provide a system that can

In this way, this embodiment uses the comment text while looking at the image to accurately determine the opinions of many people, not just the opinions of individuals, and while everyone is enjoying and communicating, By leaving a particularly important image and displaying it preferentially, it is possible to prevent an important image evaluated by many viewers from being lost.

In the description of the embodiments of the present invention, a combination of a digital camera and a mobile phone has been described as an example, but the digital camera includes various digital cameras such as a compact type digital camera and a single-lens reflex type digital. . In addition to a general mobile phone, the mobile phone includes a mobile communication terminal with a built-in mobile personal computer, and any mobile device capable of generating text data may be used.
