Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have.

Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen).

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

Further, the controller 180 may control any one or a plurality of the above-described components in order to implement various embodiments described below on the mobile terminal 100 according to the present invention.

The power supply unit 190 receives external power and internal power under the control of the controller 180 and supplies power necessary for operation of the respective components. The power supply unit 190 includes a battery, the battery may be an internal battery configured to be chargeable, and may be detachably coupled to the terminal body for charging or the like.

In addition, the power supply unit 190 may include a connection port, and the connection port may be configured as an example of an interface 160 through which an external charger for supplying power for charging the battery is electrically connected.

As another example, the power supply unit 190 may be configured to charge the battery in a wireless manner without using the connection port. In this case, the power supply unit 190 may use at least one of an inductive coupling method based on a magnetic induction phenomenon from an external wireless power transmission apparatus and a magnetic resonance coupling method based on an electromagnetic resonance phenomenon Power can be delivered.

Meanwhile, the mobile terminal 100 according to the embodiment of the present invention can clusters and group previously stored pictures in various ways so that the user can find the desired photo more easily and quickly. For example, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention can store the information about the time at which each photograph was taken corresponding to each photograph, and group the photographs using the time information have. For example, the control unit 180 may group previously stored pictures based on time information corresponding to each picture for a predetermined period of time, for example, month or year, according to the user's selection. As a result, the user can easily and quickly search for a desired image.

However, grouping the photographs according to the photographing time information has a limitation in selecting only the photographs desired by the user. For example, when photographs are grouped according to only the photographing time, the photographs include all the photographs photographed within a certain period selected by the user as one group. Accordingly, even when the user wants to enjoy the travel photograph taken in a specific period, other photographs taken in the same period can be included in the same group as the travel photographs. Therefore, the user can enjoy not only travel photographs but also other photographs (for example, business photographs).

In order to solve such a problem, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention can store not only the time information but also the position information at the time when the pictures are taken, corresponding to each picture. Therefore, the control unit 180 can group photos taken at the same position on the basis of the position information corresponding to each photograph. Accordingly, the user can enjoy the pictures by selecting only the group of the pictures taken at the specific place.

In addition, in the mobile terminal 100 according to the embodiment of the present invention, it is also possible to group pictures photographed at a specific place by each time zone using the information about the photographing time. In this case, the control unit 180 groups the pictures photographed during a predetermined period selected by the user according to the place where the pictures are taken, thereby making it easier for the user to find the pictures to be appreciated, .

In addition, it is needless to say that the controller 180 of the mobile terminal 100 according to the embodiment of the present invention can analyze the image itself and group the photographs based on the analyzed result. For example, the control unit 180 may extract a background image from the photographed photographs, and may infer the place where the photographed photograph was photographed using the extracted background image. In other words, the controller 180 recognizes the feature portion of the extracted background image and determines whether the place where the photograph was photographed is recognized as 'acid' or 'sea', or 'coastal' or 'riverside' Can be deduced. The control unit 180 may group the pictures having the same reasoning result into the same group, using the reasoning result about the place where the pictures were taken. Of course, the control unit 180 may use a foreground image instead of a background image to infer the photographing place of the photograph.

In addition, the controller 180 of the mobile terminal 100 according to the exemplary embodiment of the present invention extracts image objects constituting an image of each photograph, and groups the photographs using a result of analyzing the extracted image objects . For example, the control unit 180 extracts an image of a person or objects included in a photograph into respective image objects, and deduces an event related to the photograph according to the characteristics of each person image object or object image object It is possible.

For example, the control unit 180 can analyze the image of the person included in the photograph, and can recognize the posture or the expression, or the age range, the dress, etc., taken by the person. For example, the control unit 180 can analyze whether the person is jumping, standing, or standing, from the shape of each joint in the image of the person. Also, the controller 180 may analyze the facial expression of the person by analyzing the eyes, the mouth, and the like from the image of the face portion of the person. In addition, the control unit 180 may determine whether the image of the person includes a characteristic point of the clothes of the person, for example, a wrinkle or an ornament with many clothes, a short-sleeved or short- Necktie) to determine whether the garment is a suit.

The control unit 180 can deduce an event related to the photograph using the analysis result of the person image. For example, the control unit 180 may be able to infer that the faces of the characters included in the photograph are happy faces, and that when the clothes the characters wear are suits or wedding dresses, the photographs are photographed in 'wedding' have. Alternatively, if the characters included in the photograph have a tense look and the posture of the characters is running or running, and the clothes of the characters are shorts or short-sleeved clothes, It can be deduced that it is a photograph. The control unit 180 may group photos having the same reasoning result into the same group based on the result of the speculation.

Meanwhile, the controller 180 can deduce not only a portrait image object but also an event related to the photograph using an object included in the photograph. For example, the control unit 180 can analyze an image of an object of a predetermined size or more from the image of the photograph to deduce an event related to a place or a photograph where the photograph was taken from the characteristic point of the object. Alternatively, if the object includes a character recognizable image, the control unit 180 may perform character recognition on the image, and may infer the event related to the photograph based on the character recognition result. In addition, the controller 180 can deduce an event related to the place where the photograph was taken or the photograph, using a web search for the minutiae points of the image of the object.

The control unit 180 of the mobile terminal 100 according to the embodiment of the present invention includes an image analysis unit 181 and a reasoning unit 182 in order to deduce an event or a shooting place based on the image analysis result . The image analyzing unit 181 and the reasoning unit 182 may be implemented in the control unit 180 or may be implemented separately from the control unit 180 outside the control unit 180. [

Meanwhile, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention may select one of the grouped pictures as a representative picture of each group so that the user can easily and quickly find a desired picture, The representative photograph may be displayed on the display unit 151 based on the characteristics of the grouped photographs. For example, the control unit 180 can display a representative photograph of a group including many photographs on the display unit 151 in a relatively larger size than a representative photograph of a group that does not include the representative photograph. Further, the control unit 180 may display a graphic object for displaying information related to a grouping criterion such as a grouping criterion, that is, a grouping criterion such as the above-mentioned event, It may be displayed on at least a part of the area on the display unit 151 on which the photograph is displayed. Here, the graphic object may be text information for the grouping criterion, or map or navigation information indicating a specific place.

The control unit 180 may display such a graphic object in a representative photograph of a certain size or more, that is, a representative photograph of a group having a predetermined number of or more than the number of the photographs included in the corresponding group. In addition, the controller 180 may display the graphic object on only one representative photograph based on the user's gaze. For this, the sensing unit 140 of the mobile terminal 100 according to the embodiment of the present invention may include a visual recognition sensor 143 for sensing the user's gaze, and the sensing unit 140 may include a visual recognition The movement of the user's line of sight and line of sight can be sensed through the sensor 143. [ Accordingly, the control unit 180 may display the graphic object only on one representative photograph corresponding to the sight line of the sensed user, among the representative photographs displayed on the display unit 151 at this time. Also, in this case, the control unit 180 may display the graphic object only when the representative picture corresponding to the user's gaze has a predetermined size or greater.

In the above description, the controller 180 classifies pictures having the same reasoning result into the same group. However, the controller 180 may perform the classification of the reasoning result and the photographing time and the photographing location together Of course it is. For example, when there is a picture having a clear inference result, that is, a picture having a certain degree of certainty, the control unit 180 generates a grouping criterion based on the inference result of the picture, It is also possible to group other photographs taken during a time within a predetermined range of time, that is, photographs taken at the same time, or photographs taken at a place where the reasoning result is clear, into groups according to the grouping criterion. In this case, the control unit 180 can clearly group only the pictures photographed in the specific event into the photographs related to the specific event, without performing the image analysis on all the previously stored photographs.

In the following, various embodiments may be embodied in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

2 is a flowchart illustrating an operation procedure of the mobile terminal according to the present invention.

2, the controller 180 of the mobile terminal 100 according to the exemplary embodiment of the present invention may generate a grouping criterion for previously stored pictures and group the pictures based on the generated grouping criterion (S200). Here, as described above, the control unit 180 may generate the grouping criterion based on the information about the photographing time or the photographing place stored corresponding to each photograph. Alternatively, as described above, the grouping criterion may be generated based on an analysis of images of each photograph, and based on the analyzed result, an event related to the photographs or a result of inferring the place where the photograph was photographed. Hereinafter, an operation of analyzing images of each photograph and generating a grouping criterion according to the analysis result and grouping the photographs according to the generated grouping criterion will be described in more detail with reference to FIG.

In addition, the controller 180 sets a predetermined classification criterion such as time, place, event, or person, classifies each photograph according to each classification criterion, and then displays the photographing time, Such as an event related to the event.

When the grouping of the pictures is completed (S200), the controller 180 selects a representative picture among the pictures included in each group (S202). For example, the control unit 180 may select the first photographed image or the latest photographed image in the group as the representative photographed image.

Alternatively, the control unit 180 may select a photograph having the most specific inference result as the representative photograph in the case of photographs grouped according to a result of inferring a photograph-related event or a place where the photograph was photographed. For example, in the case of the photos grouped according to the reasoning inferred as 'wedding', the control unit 180 may select a photograph including a person who is recognized as wearing a 'wedding dress' as a representative photograph. In addition, the control unit 180 may select a photograph having the most definite character recognition result as a representative photograph when the photographs of the group are photographs grouped based on the character recognition result of the image recognizable by the character.

In addition, the control unit 180 may display a representative image of a specific region or place, which is searched from the web, among photographs of the group, based on a result of performing a web search on the object image, A photograph including an object image having the most similar characteristics to the representative image of the group may be selected as the representative photograph of the group. The operation of the controller 180 for selecting representative photographs in various ways will be described in more detail with reference to the drawings in FIG.

The control unit 180 may display the representative pictures of the respective groups based on the number of pictures included in each group (S204). That is, the control unit 180 may display the representative pictures on the display unit 151 differently based on the number of pictures, and a graphic object indicating the number of pictures may be displayed on the display unit 151 In the vicinity of the area on the screen.

The control unit 180 may display at least one graphic object related to the grouping reference of the group corresponding to at least one of the displayed representative pictures (S206). For example, the control unit 180 may display the graphic object only on at least one representative photograph displayed in a size larger than a predetermined size among the representative photographs. The graphic object may be for displaying information related to a common feature of the photographs included in the corresponding group, that is, the grouping criterion, as described above, and may be text information or a location where the pictures of the corresponding group are photographed It may be map information to be displayed.

Meanwhile, FIG. 3 is a detailed view illustrating an operation of creating a grouping criterion and grouping pictures in the operation procedure shown in FIG. 2, as described above.

Referring to FIG. 3, the control unit 180 analyzes an image of previously stored pictures (S300). For example, the control unit 180 may divide the image of each photograph into a background image and a foreground image according to whether the focal points match each other. That is, the control unit 180 divides an image of a portion corresponding to the photographed focus, for example, a contour or a portion of a color with a predetermined level or more in color, into a foreground image, The image of the outline or faded part can be divided into the background image.

The control unit 180 analyzes the divided background image or foreground image to deduce a place or an event in which the image is captured (S302). For example, the control unit 180 analyzes the background image or the foreground image, and compares the feature point portion of the background image or the foreground image with feature information of a plurality of places previously stored in the memory 170, Can be deduced. That is, if the background image includes an image of a ridged shape, or if the foreground image includes image objects recognizable as' trees', the control unit 180 determines whether the place where the photo was taken is' Mountain '. Or if the background image includes a horizontally-shaped image, or if the foreground image includes image objects that can be recognized as a 'ship' or a 'sandy beach', the control unit 180 determines It can be deduced that it is a 'beach'.

Here, the characteristics of the image that can be recognized as the 'ridiculous' image or 'tree' and the information about the characteristics of the image that can be recognized as 'horizontal line' or 'boat' or 'sandy beach' Quot; feature information of the places ". The feature information may be stored in the memory 170 or downloaded from the manufacturer or the web of the mobile terminal 100.

Alternatively, the control unit 180 may divide the image objects constituting the images of the photographs into a portrait image and a subject image, as described above, and may infer the place or event where the photographs are taken according to the minutiae points of the respective image objects . For example, in the case of a portrait image, the controller 180 can recognize the posture taken by the person based on the image of the joint part of the image of the person, as described above. Also, the controller 180 can analyze the facial expression of the person based on the image of the facial part of the person, and can determine the emotional state of the person based on the analysis result of the facial expression. For example, in the case of a person whose facial expression is smiling, the control unit 180 can determine that the emotional state of the person is a joy state. In the case of a person with a solid facial expression or bowing his head and pointing his gaze in a specific direction, It may be determined that the emotional state of the person is in a state of tension. In addition, the control unit 180 may determine the age range of the person based on the analysis result of the face image of the person.

Further, the control unit 180 can further analyze 'clothes' worn by the characters from the images of the characters included in the photograph. For example, the controller 180 may analyze the length of the sleeves, the length of the trousers, etc. of the clothes the characters wear, and determine whether the characters are wearing shorts or short-sleeved clothes. In addition, the controller 180 can determine the clothes the characters are wearing from the characteristic parts such as the color of the clothes and the ties.

The control unit 180 can deduce a place or an event where the corresponding photograph is photographed based on the determination result. For example, if the age group includes many young characters, the attitude of the characters is running or running, the emotional state of the characters is strained, and the clothes the characters wear are shorts or short- And the garment having little ornaments, the control unit 180 can infer that the photograph is photographed in the 'athletic meet' of the children. Alternatively, the controller 180 may include a plurality of middle-aged persons, a person in a standing posture, a person with a smiling expression, and a person wearing a formal or wedding dress including a tie or the like It can be inferred that the photograph was taken at the 'wedding'.

Also, in the case of the object image included in the photograph, the control unit 180 can deduce from the shape of the object image, etc., the place or event where the photograph was taken. For example, the control unit 180 may perform a web search for an object image, and may infer a place where the photograph was taken based on a web search result. For example, in the case of a photograph in which a specific cultural property (for example, 'Dabotop') is photographed, the control unit 180 can obtain a web search result for the image of the cultural property from the photograph, (E.g., " Gyeongju Bulguksa Temple ") can be deduced as the place where the photograph was taken.

Alternatively, when the object image included in the photograph includes an image recognizable as a character, the controller 180 may use the character recognition result. For example, when the control unit 180 has a phrase "celebrate birthday" in an image of an object, for example, a banner included in a photograph, the controller 180 performs character recognition on the phrase , It may be judged that the photograph was taken at the "birthday party".

Also, in the above description, it has been explained that a place or an event in which a photograph is photographed is inferred according to each case, and the controller 180 comprehensively judges such cases, It is also possible to deduce a place or an event.

For example, the control unit 180 can infer an event related to the pictures or a place where the pictures were taken according to a result of the inferred result of the object image, have. For example, the controller 180 may determine that the inference result (for example, character recognition result) from the image of the person's dress or object rather than the face or the attitude of the person has a higher degree of clarity of reasoning. In this case, even if the facial expression or attitude of the characters included in the photograph does not match the inferred result based on the outfit or character recognition result of the characters, Or on the basis of the inferred result according to the character recognition result.

In step S304, the controller 180 may generate a plurality of grouping criteria based on the inferred result in step S302. For example, the grouping criterion may be an inferred result based on the 'feature information of a plurality of previously stored places' or an inferred result based on the image of the person and the object image, It may be information. Then, the controller 180 groups the previously stored photographs based on the generated grouping criteria (S306). Accordingly, the pictures having the same reasoning result can be a group. Accordingly, the user can easily search a desired picture by selecting a desired group, or can accurately select only a specific event or a picture taken at a specific place.

Meanwhile, in the above description, it has been explained that the location or the event where the photograph was photographed was inferred using the analysis results of the previously stored photographs, but it is needless to say that it is not necessary to analyze all the photographs. For example, the control unit 180 may extract previously displayed photographs of specific events or places from pre-stored pictures. Here, pictures with specific events or places clearly marked are those that contain images that clearly show where the photos were taken or where the events were to be inferred.

Here, the 'clear image' may be a specific clothing or a specific phrase. For example, in the case of a photograph including a clothing image such as a 'wedding dress', the 'wedding dress' image may be an obvious basis for the inference result that the photograph is a 'wedding'. In this case, the control unit 180 may group the photographs taken at the same place in the same time zone as the photographs including the 'wedding dress' image into the photographs taken at the 'wedding'.

Also, for example, in the case of a photograph including an image including a phrase "Celebrate a birthday ", the above phrase may be a clear basis for the inference result that the photograph is a birthday party. In this case, the control unit 180 may group the pictures photographed at the same place in the same time zone as the photographs including the phrase, into the pictures photographed at the 'birthday party'.

Meanwhile, the controller 180 of the mobile terminal 100 according to the embodiment of the present invention may classify the grouping criteria generated in step S302 according to a plurality of predefined classification items according to the attributes. When the user selects a specific category item, the grouped photos are displayed on the display unit 151 according to the grouping criterion corresponding to the attribute of the category item, It is easier and faster to find.

For example, the control unit 180 may have a plurality of predetermined classification criteria, such as a time line, a place, an event, and the like. In this case, the control unit 180 may classify the grouping criteria by time, place, and event attribute. For example, if the grouping criterion generated in step S302 is a name of 'mountain', 'sea', or a specific scenic spot or a specific place, the controller 180 may classify the grouping criterion as a 'place' item. Alternatively, when the grouping criterion is 'wedding', 'birthday feast', or 'athletic meet', the control unit 180 may classify the grouping criteria as an 'event' item. Here, the grouping criteria may be automatically classified into any one of the classification items according to an attribute of the user, but the attribute may be determined as a specific classification item according to the user's selection.

Meanwhile, FIG. 4 is a conceptual diagram illustrating an example in which pictures are grouped based on grouping criteria classified according to a predetermined classification criterion in FIG.

Referring to FIG. 4, the controller 180 classifies the reasoning results of step S302 into time 400, place 404, event 406, and the like. In addition, FIG. 4 shows that the category 406 includes the character 408. This is because, in the case of the mobile terminal 100 according to the embodiment of the present invention, the image of the face portion of the person included in the specific photograph is analyzed , And photographs including the same face image may be grouped based on the image of the face portion.

As shown in FIG. 4, when the classification items including the person 408 are set, the control unit 180 classifies the currently generated grouping criteria by classification items based on the respective attributes. For example, the classification item 'time 400' may include grouping criteria 410 and 412 for a certain period, and the category item 'place 404' may include grouping criteria 420, 422, 430, and 432 may be included. In the category item 'place (404)', position information 420 or 422 obtained as a result of web search for the feature point of the object image included in the photograph or the image information stored in correspondence with the photograph at the time of photographing is included as a grouping reference Or the result 430 or 432 derived from the background image or the foreground image of the photograph may be included as a grouping criterion.

In addition, the classification item 'event' may include inferred results 450 and 452 according to the result of recognizing from the clothing, the attitude expression of the person included in the photograph, the phrase of the object, and the like. In the category item 'character 408', the face images 460 and 462 of a specific person may be included as a grouping reference.

On the other hand, when the grouping of the pictures is completed, the controller 180 selects one of the grouped pictures as a representative picture in order to make it easier for the user to know what pictures the grouped pictures are related to, It may be displayed on the display unit 151 instead of the grouped pictures. If the grouping of photographs is performed according to the inference result of any one of the well-defined photographs as described above, it is also possible to select a photograph with the clear grounds as the representative photograph.

However, it is needless to say that the control unit 180 may select a photograph that satisfies a specific condition among photographs included in the same group as a representative photograph.

FIG. 5 is a detailed view illustrating an operation of selecting a photograph satisfying a specific condition as a representative photograph.

Referring to FIG. 5, the controller 180 of the mobile terminal 100 according to the embodiment of the present invention determines whether or not the foreground region of the photos included in the same group and the saturation and brightness are higher than a predetermined level Pictures can be selected (S500). Here, the foreground region refers to a region of a portion corresponding to the focus from a photographic image. The wider the foreground region, the clearer the picture is, and the narrower the foreground region is, It can be judged that it is a cloudy photograph. This is to prevent images that are basically out of focus, that is, photographs that are erroneously photographed by the user, or images that are too blurry or dark to identify persons or objects as representative images. Here, the predetermined level may be increased or decreased according to the user's selection.

On the other hand, if the photographer has a certain level of saturation and brightness over the predetermined level and the photographer selects a photograph with a certain level or higher, the controller 180 may select representative photographs according to a predetermined criterion for classification item destruction or grouping criteria (S502).

For example, the control unit 180 may have a different representative picture selection criterion for each classification item. That is, in the case of the groups in which the classification item is included in the 'person', the control unit 180 determines that the 'face' image of the person who is the grouping reference among the pictures of each group is a photograph having a certain size or more and / 'The image of the expression can be selected as the representative picture of the expression of the smiling expression. Or if the category item is a 'place', the control unit 180 performs a web search for the place, and may select a photograph having the most similar characteristics to the representative image of the corresponding place searched from the web, as the representative photograph.

Or the control unit 180 may have different criteria for each grouping criterion. For example, when the reason for reasoning the grouping criterion is a clothing worn by a specific person included in the photograph, the control unit 180 determines that the focus is on the person wearing the garment or the garment and the sharpest, that is, May select the highest picture as the representative picture of the group. Similarly, when the reason for reasoning the grouping criterion is a character image included in a specific photograph, the control unit 180 may select the sharpest photograph among the photographs including the character image as a representative photograph of the group have.

In addition, the control unit 180 may select a photograph that is determined to have the best color feeling as a representative photograph. For example, when the place where the photograph was photographed is outdoor and the time at which the photograph was photographed is evening, the control unit 180 displays a photograph having high color saturation such as a color having cool color, for example, blue or white as a representative photograph It may be elected. On the other hand, when the photographed time is the daytime, a photograph having high color saturation such as red or yellow may be selected as the representative photograph. That is, the control unit 180 can select a preferred color based on the location where the photographs included in the group are photographed, the photographed time or the event, and select a specific photograph as a representative photograph of the group according to the selected color It is possible.

Meanwhile, in the mobile terminal 100 according to the embodiment of the present invention, the selected representative photographs are displayed differently according to the number of pictures included in the corresponding group so that the user can easily and quickly find desired pictures I have stated earlier. A graphical object for displaying information related to the grouping criterion may be displayed on at least a part of the area on the display unit 151 on which the representative picture is displayed.

FIG. 6 shows an operation of displaying a graphic object related to the grouping criteria on the representative picture in more detail.

6, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention displays representative pictures selected for each group in step S204, based on the number of pictures included in each group, If the representative photographs are displayed on the display unit 151, representative photographs having a size larger than a predetermined size displayed on the display unit 151 are selected (S600).

In step S602, the controller 180 generates graphic objects for displaying information related to each grouping criterion of groups corresponding to the selected representative photographs. Here, the grouping criterion is a result of inference of a place or an event where photographs belonging to each group are photographed, as described above, and may be a common point of the photographs included in the group. Therefore, the grouping criterion can be a feature of the group.

Also, graphic objects for displaying information related to the grouping criteria may be various. For example, the control unit 180 may generate a graphic object in the form of a text including information related to the grouping criteria. Alternatively, the control unit 180 may generate the graphic object with an image related to the grouping reference of the group so that the user can intuitively recognize the grouping reference of the photos included in the group. For example, the control unit 180 may generate an icon image corresponding to the inference result of the group as the graphic object, or, if the inference result is for a specific place, A thumbnail map image corresponding to a position on the map of the thumbnail image may be generated as the graphic object. Here, the control unit 180 may generate at least one graphic object.

In step S604, the control unit 180 displays the generated at least one graphic object on the display unit 151 on which at least one representative picture is displayed. For example, the controller 180 displays at least one graphic object corresponding to each of the representative photographs selected in step S600, that is, representative photographs displayed on the display unit 151 at a predetermined level or more in size, Or a graphic object corresponding to the corresponding representative photograph may be displayed in only one representative photograph based on a predetermined selection criterion.

For example, the control unit 180 selects at least one representative photograph displayed on the display unit 151 according to a preset size (for example, from top to bottom, from left to right) The corresponding graphic object may be displayed. Alternatively, the control unit 180 may display only one representative picture selected by the user, such as a touch input, among the representative pictures displayed at a predetermined size or more, and display the corresponding graphic object on the display unit 151 And may be displayed on at least a part of the area.

Alternatively, the control unit 180 can select any of the representative photographs displayed on the display unit 151 based on the sight line of the user sensed through the sensing unit 140. The control unit 180 may display a graphic object corresponding to the selected representative picture in an area on the display unit 151 where the selected representative picture is displayed. In this case, when the movement of the user's gaze is detected, the control unit 180 selects another representative picture corresponding to the moved visual line, and the graphic object corresponding to the selected representative picture is displayed on the display unit 151 may be displayed on at least some areas. An example of at least one graphic object displayed in response to the user's gaze movement will now be described in detail with reference to FIG.

In the above description, the operation flow of the mobile terminal 100 according to the embodiment of the present invention has been described in detail.

Hereinafter, an example of grouping pictures based on the operation procedure described in FIGS. 2 to 6 in the mobile terminal 100 according to the embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 7 illustrates an example in which pictures grouped in the mobile terminal related to the present invention are displayed.

7 (a) and 7 (b) show an example in which pictures are grouped on the basis of respective grouping criteria by a predetermined period (month). 7 (a) is a diagram illustrating photographs taken in August 2013 according to the place where the photograph was taken, the person included in the photograph, and the event related to the photograph. Respectively.

7 (a), the controller 180 can display the size of representative pictures differently based on the number of pictures included in each group. Accordingly, the controller 180 can display the pictures included in the group 1 700 The number of pictures included in group 2 702 and group 3 704 is similar and the number of pictures included in groups 4, 5 and 6 706, 708, and 710 is the most .

Also, as shown in the representative photographs of the respective groups, the groups 700, 702, 704, 706, 708, and 710 are grouped into different grouping criteria. For example, group 1 700 is a grouping of photographs where the place where the photograph was taken is inferred as 'Seashore', as can be seen from graphical object 710. The group 2 702 and the group 4 706 are grouped based on the face image of a specific person as shown in the elected representative picture and the group 3 704 and the groups 5 and 6 708 and 710 It is shown that each event is grouped based on grouping.

If another time period is selected by the user, the mobile terminal 100 according to the embodiment of the present invention analyzes images of photographs photographed in different selected time periods and groups them based on the analyzed results. FIG. 7B shows such an example, and the group 7 750 shows an example of grouping the photographs in which the event related to the photograph is inferred as 'Wedding'. That is, in the mobile terminal 100 according to the embodiment of the present invention, the image of the photographs photographed during the period selected by the user (December, 2013) is analyzed, and an event related to the photographs or a place where the photographs are taken is inferred , And group photos based on the inference results (grouping criteria).

As described above, in the mobile terminal 100 according to the embodiment of the present invention, it is possible to generate pictures having the same reasoning result in the same group, using the inferred results based on the analysis results of images as a grouping reference. Therefore, the present invention analyzes the image itself of the photograph, not the location information of the mobile terminal at the time of photographing or photographing, and groups the photographs according to contents included in the image of the photograph, Allows you to search for images you want to search or watch.

It is needless to say that the user may directly designate grouping of photographs according to the grouping criterion.

FIG. 8 shows an example of a screen in which a user directly sets a grouping criterion.

For example, as shown in FIG. 8 (a), the user may set different grouping criteria for each hour, place, and person, or may set specific conditions for grouping the pictures.

For example, when the user selects' time 900 'in the setting shown in FIG. 8 (a), the controller 180 of the mobile terminal 100 according to the embodiment of the present invention selects the' the setting screen shown in Fig. 6B can be displayed on the display unit 151. [ Then, the user can selectively change a predetermined period or the like that can be set as the grouping reference in the grouping reference setting by time shown in (b) of FIG.

Alternatively, the user may set a specific time, and when a predetermined number or more of photographs are photographed at a set time, they may be set to be generated in one group. For example, as shown in FIG. 8B, the user selects 'duration 810' and 'number of pictures 812', and for a predetermined time (for example, 3 hours) , Or when a predetermined number (for example, 30 or more) of photographs are photographed, a specific group may be generated.

In addition, it is needless to say that the user can directly set the group size in the setting screen shown in FIG. 8 (b). For example, as shown in the group setting 814 shown in FIG. 8B, the user may select a small group if the number of pictures is 1 or more, a middle group if the number of pictures is 10 or more and less than 30, If it is more than 30, it can be set to group into large groups.

8 (a), the controller 180 of the mobile terminal 100 according to the embodiment of the present invention selects the 'location 802' from the setting screen shown in FIG. 8 (a) c) on the display unit 151 as shown in FIG. In addition, the user can set the groups of the photographs taken at a specific place to be grouped into a specific group or not to group the pictures taken at a specific place in the grouping reference setting of each place shown in (c) of FIG.

For example, when the user selects 'Exception Place (820)' on the setting screen shown in (c) of FIG. 8, the control unit 180 displays Grouping may not be performed. Or 'Special Place', the control unit 180 may group pictures taken at a place designated by the user into a specific group. Here, the control unit 180 may receive an address for a specific place from the user, or may display a map related to the location designation on the display unit 151, and may receive position information on the specific place from the map. Here, the control unit 180 displays a graphical object related to the movement of the mobile terminal 100 on the map, thereby displaying a place where the user mainly stays on the map, You may also be able to enter information.

On the other hand, when the user selects the 'person 804' on the setting screen shown in FIG. 8A, the control unit 180 displays a setting screen as shown in FIG. 8D on the display unit 151 ). ≪ / RTI > For example, the user may set the photographs including the face of a specific person to be grouped separately, or may not group them for a specific person, similar to the one shown in FIG. 8B.

For example, in the setting screen shown in FIG. 8D, the user can register a face image of a specific person in 'Except People 830'. In this case, the controller 180 may analyze the face image of the person registered in the 'non-person 830' to prevent the pictures from being grouped on the basis of the person, or may be grouped according to another grouping criterion The photographs including the persons registered in the 'non-person 830' may be excluded from the photographs. Also, in the case of a person registered as 'Special People 840', the control unit 180 analyzes the face image of the person registered in the 'specific person 840' They may be grouped into specific groups.

Here, the control unit 180 may display predetermined pictures on the display unit 151 in order to register a face image of a specific person from the user. Here, the predetermined pictures may include pictures downloaded from a social network service (SNS) or pictures downloaded from the web or an external server.

The control unit 180 may extract the face images of the persons included in the specific photo selected from the user and display the extracted face images on the display unit 151. [ If at least one of the face images is selected, the control unit 180 may register the selected face image as the 'non-person 830' or the 'specific person 840'.

Meanwhile, according to the above description, the mobile terminal according to the embodiment of the present invention has mentioned that each grouping criterion generated at present can be classified according to a plurality of predetermined classification items according to the attribute.

FIG. 9 is an exemplary view showing another example in which pictures grouped in the mobile terminal related to the present invention are displayed in this case.

8, (a), (b), (c), and (d) of FIG. 8 illustrate an example of a classification of a category item by a time line, a place, an event, Are set. In this case, the control unit 180 may classify the grouping criteria into one of the category items based on the attribute of the grouping criteria generated according to the result of analyzing the image of the currently stored pictures.

Referring to FIG. 9 (a), FIG. 9 (a) shows an example in which the classification item 'time 900' is selected. If the category item 'time 900' is selected as described above, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention may search for the photographing time information of each photograph. Each photograph is classified according to a predetermined period. As described above, a representative picture is selected for each group, and the size of the representative picture displayed on the display unit 151 is determined according to the number of pictures included in the group. For a group having a size of the representative picture of a certain level or higher, information related to the grouping criterion of the group, that is, information related to the time at which the pictures included in the group are photographed, can be displayed using a graphic object. As described above, in the mobile terminal 100 according to the embodiment of the present invention, the photographs can be grouped according to the photographing time by predetermined period.

On the other hand, FIG. 9B shows an example in which 'place 910' is selected as a classification item. When the category item 'place 910' is selected as described above, the control unit 180 groups each photograph based on the inferred 'photographing place' based on the result of analyzing the images of the respective photographs. Here, the control unit 180 can deduce the location where the photographs were taken according to the location information of the mobile terminal 100 recorded at the time the photographs were taken, or analyze the images of the photographs, You can also infer where the photos were taken.

Accordingly, the pictures grouped in FIG. 9B may be similar photographs as the result of analyzing the images of photographs, such as 'beachfront 912', or may be similar photographs such as 'Gyeongju Bulguksa' or 'Busan Haeundae' As shown in FIG. As described above, when the 'place 910' is selected as the category item, the control unit 180 can display the photos grouped according to the grouping reference related to 'place' on the display unit 151.

Similarly, FIG. 9 (c) shows an example in which 'event 920' is selected as the classification item. If 'event 920' is selected as the category item, the control unit 180 groups each picture based on the inferred 'event' based on the result of analyzing the images of the respective pictures. For example, the control unit 180 can infer events related to photographs by analyzing the facial expression, posture, age of a person, clothing of a person, and the like, from a portrait image included in each photograph. Alternatively, the control unit 180 may analyze the shape of the object, characters, or the like from the images of the objects included in the photographs to deduce an event related to the photographs.

Then, the controller 180 groups the pictures based on the event reasoning result of each picture. Accordingly, the control unit 180 may group the pictures into grouping criteria such as 'wedding', 'athletic meeting', or 'birthday party', and display and group representative pictures according to the number of pictures included in each group You can display graphical objects related to the criteria. FIG. 9C shows an example in which when the classification item 'event 920' is selected, the reasoning results are grouped according to the grouping criteria related to 'event'.

Also, in the mobile terminal 100 according to the embodiment of the present invention, the photographs may be grouped based on the 'person 930'. For example, when the user selects the classification item 'person 930' as shown in FIG. 9D, the control unit 180 analyzes the 'face' portion of the person image included in the photograph, Photographs containing the same people can be grouped into the same group. When the category item 'person 930' is selected as described above, the control unit 180 can display the photos grouped on the basis of the face of each photograph on the display unit 151. The representative photographs of the respective groups can be the photographs in which the face of the person as the grouping reference of each group is best displayed. For example, the control unit 180 can select, from the pictures included in the group, a picture whose saturation or lightness is equal to or higher than a certain level and whose focal point matches the face of the person as a grouping criterion, A photograph in which a face of a person as a grouping reference is photographed in a larger size may be selected as the representative photograph.

10A and 10B are views illustrating an example in which pictures are grouped according to a grouping criterion generated based on an analysis result of an image object in a mobile terminal according to the present invention.

According to the above description, the mobile terminal 100 according to the embodiment of the present invention has been described in which, when an image that can be recognized as a character is contained in a photo image, it is possible to deduce an event related to the photo using the image . For example, as shown in (a) of FIG. 10A, in the case of a photograph including a character recognizable image 1000, the controller 180 performs character recognition on the image 1000, You can infer relevant events. Accordingly, if the recognized character is 'Birthday' as a result of recognizing the image 1000 as shown in FIG. 10A, the control unit 180 determines that the photo is related to the 'birthday party' Can be deduced. In this case, the control unit 180 inferred according to the result of analyzing the images of other previously stored pictures, and as a result, the event related to the corresponding photo is the 'birthday party' and the pictures shown in FIG. They can be grouped into one group.

The mobile terminal 100 according to the embodiment of the present invention may be configured such that, when there is a picture that can clearly deduce a specific event or a place where the picture is taken, For example, a group of such photographs as the clearly speculable photographs. 10A, if there is a picture that can be clearly deduced that it is a 'birthday party', the control unit 180 may display the same place in the same time zone as the picture shown in FIG. 10A (a) May be grouped into a group, that is, a group called 'birthday party 1002'.

In addition, according to the above description, the mobile terminal 100 according to the embodiment of the present invention can deduce an event related to the photograph based on the posture, facial expression, clothes, etc. of the person. Accordingly, in the case of the photograph shown in (a) of FIG. 10B, the controller 180 determines that the posture of the characters is in a large posture, for example, 'motion', based on the joint shape of the characters included in the photographic image It can be judged that it is doing. Then, the controller 180 analyzes the clothes of the characters, and if the characters are wearing sleeves and / or short skirts or short skirts, the photographer can judge the photograph as a photograph in which the characters act. In this case, the control unit 180 may group pictures having an analysis result similar to the above photographs into a group called 'Sports day (1050)'.

10B, when the controller 180 determines that the picture in which the characters are moving is clear, as in the case of FIG. 10A, Of course, the pictures photographed at the same place in the same time zone as the photograph may be grouped into one group, i.e., a group called 'athletic meeting (1050)'.

According to the above description, the mobile terminal 100 according to the embodiment of the present invention includes a graphic object for displaying information related to a grouping criterion of each group, At least in part. The graphical object can be of various forms.

FIG. 11 illustrates an example in which a graphic object related to a grouping reference is displayed in a representative picture in the mobile terminal according to the present invention.

The controller 180 of the mobile terminal 100 according to the embodiment of the present invention may display information related to grouping criteria of each group in various manners. For example, the control unit 180 may display information related to the grouping criteria of each group as graphic objects in the form of images such as graphic objects or icons. Alternatively, if the grouping criterion is position information of a specific place, information related to the grouping criterion may be displayed using a graphic object such as a map corresponding to the position information as shown in FIG. 11 (c).

In addition, the controller 180 may display graphic objects for displaying the information on all or at least one representative pictures displayed on the display unit 151. [ For example, as shown in FIG. 11A, the control unit 180 may display the graphic object only for one group, and the control unit 180 may display any group in which the graphic object is displayed It can be selected according to preset conditions.

For example, the controller 180 may select a group in which the graphic object is to be displayed according to the size of the representative picture representative of each group. Since the size of the representative picture may be determined according to the number of pictures belonging to the corresponding group, the controller 180 may display the graphic object only for a group having a predetermined number of pictures or more.

Accordingly, in the screen shown in FIG. 11, only the 'coastline' group 1100 and the 'birthday party' group 1102 can be selected as a group in which the graphic object can be displayed. In this state, the controller 180 may cause the graphic object to be displayed in all of the selected groups, or may display only one specific group of graphics objects, such as shown in FIGS. 11A and 11B, May be displayed.

Here, the controller 180 may select any one of the groups in which the graphic object is to be displayed in various manners. For example, the control unit 180 can sequentially change the group to display the graphic object at predetermined time intervals, or select one group based on the user's selection such as touch input. Alternatively, the control unit 180 may sense the user's gaze and select only one group corresponding to the user's gaze, as described above.

For example, the control unit 180 may sense the direction of the user's eyes, that is, the line of sight, based on the detection result of the sight recognition sensor 143 of the sensing unit 140. One point on the display unit 151 corresponding to the user's line of sight can be recognized, and a group corresponding to the recognized point can be selected as the group in which the graphic object is displayed. In this case, the control unit 180 may generate graphic objects corresponding to the information related to the grouping criteria, that is, information such as 'birthday party', 'wedding', 'mountain', and 'sea' . For example, the graphic object may be text information corresponding to the speculation result, or may be an image of an icon corresponding to the information.

The control unit 180 may display the graphic object in an area on the display unit 151 on which representative photographs of the currently selected group are displayed. Accordingly, when the group corresponding to the user's gaze is the 'coastal area' group 1100, the control unit 180 displays 'Seashore' in the 'coastal area' group 1100 as shown in FIG. Can be displayed as a graphic object.

If the user's gaze is moved to the area on the display unit 151 where the 'birthday party' group 1102 is displayed, the control unit 180 displays 'birthday party' as shown in FIG. 11 (b) A graphic object can be displayed in an area on the display unit 151 where a representative picture of the group 1102 is displayed. And the graphic object displayed here is for displaying information related to the grouping criteria of the birthday party 'group 1102. [ Accordingly, as shown in FIG. 11 (b), text information called 'Birthday Party' can be displayed as a graphic object.

Meanwhile, in the present invention described above, it has been explained that events and photographs related to photographs are photographed using the analysis result of the image itself of the photograph, but it is also possible to perform grouping according to specific photographs designated by the user Of course it is. For example, a specific grouping criterion may be generated according to a result of analyzing an image of a specific photograph specified by a user, or the other photographs and the corresponding photographs may be created as a group based on the generated grouping criterion. Here, the specific photograph designated by the user may be a photograph directly selected by the user with a touch input, or a photograph in which the user directly sets the title of the photograph.

That is, when there is a picture having a title designated by the user among the pre-stored pictures, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention can generate the title content on a grouping basis, And photographs taken at the same place in the same time zone as the corresponding photograph may be generated as a group according to the generated grouping criterion. Therefore, if the user sets a title for a person's name on a photograph of a specific person, the photographs including the same person as the person included in the photograph may be created as a group, The name of the person set by the user may be displayed.

The present invention described above can be implemented as computer readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). In addition, the computer may include a control unit 180 of the terminal. The foregoing detailed description, therefore, should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
