Description

  The present invention particularly relates to an image display apparatus, an image data conversion method, an image distribution system, and a program related to image distribution using the Internet.

  In recent years, with the widespread use of digital cameras, it has become common to store photographs as digital image data. In the case of shooting with a conventional film camera, it was often accompanied by printing, but in the case of image data, it can be browsed with a digital camera that has shot, or it can be browsed with a personal computer that captures image data, etc. There are also changes in the way photos are enjoyed. First, the flow of such technology and photographic culture will be briefly described with reference to patent documents.

Under the circumstances as described above, so-called digital photo frames are realized and popularized so that image data can be enjoyed in the same way as a conventional print photograph (for example, see Patent Document 1).
Such a digital photo frame can be used as an album terminal for reproducing a photograph taken and viewing it at any time, displaying a slide show, or storing image data.

  A digital photo frame that can be connected to a network and can send and receive mail has also been proposed (see, for example, Patent Document 2).

  In addition, there has been proposed a method in which information can be viewed by a plurality of people, information of a plurality of viewers is registered, and a display method or the like is changed depending on a person who browses (for example, see Patent Document 3).

  Furthermore, a technique has also been proposed in which image processing is added to generate and display an image having a different tone (for example, a painting style) based on the original photograph ( For example, see Patent Document 4).

  By developing the technology of Patent Document 4 and extracting features such as color information and brushing information from the picture of the picture actually drawn by the painter, and adding the extracted features to the photographed image, the entire original image is obtained. In consideration of this, a technique for converting to a painting-like image with high artisticness has been proposed (for example, see Patent Document 5).

  In addition, there is a proposal that changes the image quality such as painting. (For example, refer to Patent Document 6).

  Furthermore, there has been proposed an apparatus that can effectively prevent an unsuitable image from being displayed inadvertently when a plurality of images are sequentially switched and displayed as in a slide show (for example, patents). Reference 7).

On the other hand, because the capacity of memory cards has become larger and the price has become cheaper, it has become more common for families to take pictures on multiple memory cards with multiple digital cameras, making it impossible to organize memory cards. ing. If you don't know who took what photos on which memory card, you have to play it back on the camera or digital photo frame, check it, and then organize it again in a folder on your computer etc. There is.
Therefore, a technique has been proposed in which when a large amount of images are stored in a personal computer, folders are automatically divided according to preset contents, and image organization is efficiently performed according to the classified contents (for example, patents). Reference 8).

Such a conventional digital photo frame has a problem that it is unsatisfactory because it only displays an image stored in a built-in or memory card.
Therefore, it has been proposed to connect a digital photo frame to the Internet and distribute various content images for a fee or free of charge (see, for example, Patent Document 9).

  According to the technique described in Patent Document 9, it is possible to receive free or paid content distributions of a plurality of genres such as news and advertisements in a digital photo frame.

Some content distribution also distributes live video from a distant live camera. If this content distribution technology and the above-described picture conversion technology are combined, it is possible to convert pictures of live video. The live video includes a real-time moving image or a still image image data that changes every predetermined time on a server, or a video that gives a dynamic feeling by repeatedly displaying a predetermined time, for example, 5 minutes.
When converting the live video into a painting, the conventional digital photo frame could not change the atmosphere of the painting conversion according to the environment of the site on the remote live distribution side.

  Hereinafter, specific operations of the image display apparatus 1 and the network system according to the present embodiment will be described with reference to flowcharts. In order to make the explanation easy to understand, the flowchart is expressed in accordance with the operation procedure of the operator, and accordingly, the movement of the circuit and data will be described.

  FIG. 7 is a flowchart showing a procedure for registering the user's face and the user's mail address in association with each other during the initial setting of the image display apparatus 1 according to the present embodiment. First, the user's mail address is set (step S10). A method for setting the mail address of the user will be described. When the image display apparatus 1 and the authentication server 521 are connected to the network at the time of the first activation, and the authentication is received, a unique mail address is issued from the mail server 522 to the image display apparatus 1 and assigned. The mail server 522 is accessed from the personal computer 510, and the unique mail address is changed to a favorite mail address. If this e-mail address is notified to family and friends, image mail can be sent and received. This is basically the same as the initial address setting for a personal computer, portable terminal, or the like.

  Next, the user of the image display apparatus 1 (users including the owner: multiple users) registers his / her face. The image pickup device 8 takes images almost constantly while the power is on, but the user displays the mail address on the liquid crystal display panel 3 in a state where the mail address is displayed on the liquid crystal display panel 3 (step S12). When the face registration button is touched on the touch panel 5 (step S14), the CPU 11 recognizes the user's face by the face recognition engine 100, and registers the user's mail address and the user's face in the address book 33 in association with each other (step S14). Step S16).

  FIG. 8 shows a case where the image stored in the memory card 60 is stored in the internal memory 14 when the memory card 60 such as an SD card is inserted into the memory card slot 6 in the image display device 1 according to the present embodiment. It is a flowchart which shows the procedure of. First, it is determined whether or not the memory card 60 is inserted into the memory card slot 6 (step S20). When the memory card 60 is inserted into the memory card slot 6, the CPU 11 is photographed by the image sensor 8 at that time. Face recognition is performed on the face of the user who is using the face recognition engine 100 (step S22).

  Next, it is determined whether or not a personal identification code is registered for the face that has been recognized (step S24). That is, as shown in FIG. 5, since the folder is configured corresponding to the personal identification code, it is determined whether or not the recognized person's folder exists. For example, if the user does not exist, a new identification code is issued to register the face, and a folder is created (step S26). On the other hand, if the operating user is the father of the identification code “1001”, the folder F1 is selected (step S28). It is possible to prevent the image of a non-registered user from being saved.

  Next, it is determined whether or not the save button displayed on the liquid crystal display panel 3 has been pressed (step S30). When the save button is pressed via the touch key 5, the image recorded on the memory card 60 is displayed. Is copied to the corresponding folder (step S32). That is, the user (operator) can save the image in his / her folder without any particular awareness. Thereafter, according to the menu, subfolders can be created by classification within the folder, and a secret flag can be set.

  FIG. 9 is a flowchart showing a procedure when an email is received by the image display device 1 according to the present embodiment. If your e-mail address is not set in the image display device 1, you will not be able to receive e-mails in the first place, but if it is set, for example, your father's e-mail address (father@***.**.jp) If received (step S40), it is determined whether a folder corresponding to the received mail address exists (step S42). If it is determined that the corresponding folder does not exist, the received mail is stored in the shared folder F6 (step S44). On the other hand, if it is determined that the corresponding folder, for example, the folder F1 corresponding to the mail address of the father exists, the mail is stored in the corresponding folder F1 and an image is attached to the mail. In that case, the image is stored in the image mail subfolder SF4 (step S46).

  FIG. 10 is a flowchart illustrating the reproduction operation of the image display device 1 according to the present embodiment. The reproduction includes reproduction of an image stored in the internal memory 14, reproduction of an image stored on the inserted memory card 60, reproduction of only one image, reproduction of a slide show, and the like.

  When a user (operator: including a registered user and a non-registered user) comes to the front of the image display device 1 in order to reproduce an image, the image sensor 8 captures an image. The engine 100 cooperates to recognize the operator's face (step S50), determines whether or not a reproduction operation has been performed (step S52), and if there is a reproduction operation, is the user of the recognized face registered? It is determined whether or not (step S54). If the face is registered, it can be presumed that the user is the user of the image display device 1. Therefore, if the face is recognized, for example, if the recognized person is a father, it is shared with the image stored in the father folder F1. The image stored in the folder F6 can be reproduced (step S56). Other people's folders such as the mother folder F2 and the sister folder F4 cannot be reproduced without permission. On the other hand, if no face is registered, only the image stored in the shared folder F6 can be reproduced (step S58). In step S60, a predetermined reproduction operation is performed.

However, since the face recognition engine 100 can recognize the faces of a plurality of users shown in the image, the contents of the mother folder F2 can be reproduced if the mother is shown together with the father.
Note that control when a plurality of users' faces are recognized and registered users and non-registered users coexist will be described later.

  FIG. 11 is a flowchart showing a slide show playback procedure in the playback operation of the image display apparatus 1 according to the present embodiment. When it is determined whether or not there is a playback operation corresponding to step S52 of FIG. 10 (step S70), it is determined whether or not it is a slide show playback (step S72). If the slide show is not reproduced, the process proceeds to another process.

  On the other hand, if the slide show is reproduced, first, the first image is read (step S74). The slide show reproduction includes reproduction within a specific folder, old order reproduction, new order reproduction, random reproduction, and the like. Next, face recognition of the currently viewed viewer (including registered users and unregistered users) is performed (step S76). Then, it is determined whether or not the face whose face has been recognized is the face of the viewer who has browsed before (step S78). As shown in FIG. 4, a viewer code G7 is prepared for each image, and once viewed, the viewer code G7 and the number of browsing times G8 are registered as a set.

  Therefore, when it is determined that the face recognized face is not the face of the viewer who has browsed before, the playback target image is an image that has not been viewed by the face recognized viewer. Display is performed (step S80), a viewer code is issued, registration of a face image and addition of the number of browsing are performed (step S82). On the other hand, if it is determined that the face-recognized face is the face of a viewer who has browsed before, the face-recognized viewer has seen the image to be played back before, Steps S80 and S82 are skipped and the process proceeds to step S84.

  Next, it is determined whether or not there is an interrupt (step S84). In other words, this is a process when the currently viewed viewer changes while an image is displayed, or when a new viewer is added. In this embodiment, face recognition is performed before selecting an image to be displayed. However, since the slide show continues to display the same image for several seconds, naturally, there are no more viewers during that time, and the number of viewers increases or changes. It is possible to do.

  Here, a countermeasure is assumed when the image being displayed is not suitable for viewing by a person other than a specific person or the owner. For example, when the face of a person other than the family is detected, that is, when there is an interrupt, the display is stopped or another image is read and replaced (step S86). A specific image for replacement may be prepared. Although this interrupt processing is expressed at this position in the flowchart for convenience, it can be accepted at any time by an interrupt signal.

  Also, when a new viewer other than the owner is added while displaying the image read from the subfolder SF3 with the secret flag set, the process proceeds to step S86 and the display is stopped or another image is displayed. Read and replace.

  Then, it is determined whether or not there is an end instruction (step S88). If there is no end instruction, the process returns to step S74 to read the next image, and the above-described processing is repeated. On the other hand, if there is an end instruction, the process ends.

  That is, in this embodiment, when displaying a slide show, the same image is repeated over a long period of time, so there is a possibility of getting tired of viewing. The image which is not seen is displayed.

  The flowchart shown in FIG. 11 does not describe in detail, but when there are a plurality of viewers, an image that no one has seen> a group of people who have never seen> a view of all Prioritize in the order of That is, an image that no one has seen is classified as a first priority, an image in which people who have not seen it are mixed is classified as a second priority, and an image that everyone has seen is classified as a third priority.

  First, images belonging to the first priority are displayed as a slide show. When all images belonging to the first priority are displayed, images belonging to the second priority are displayed as a slide show. If all the images belonging to the second priority have been displayed, the images belonging to the third priority are displayed as a slide show. If all the images belonging to the third priority are displayed, the slide show from the images belonging to the first priority is displayed. Run the display again.

  Of course, the above processing is an operation in a state where the number of viewers or members does not change at a certain moment, and whenever the number of viewers or members changes, the first, second, and second The three priority categories will change.

  Further, an image with the secret flag G6 is not displayed from the beginning. It may be displayed only when it is recognized by the face recognition that it is the owner of the image. In that case, the display is stopped in step S86 at the moment when the face of another person is detected in step S84.

  Note that the images displayed according to the flowcharts shown in FIGS. 10 and 12 relate to images that have not undergone tone conversion, and the images that have undergone tone conversion can be slid and displayed without any limitation. In this case, for example, on the condition that the slide show mode is set, the images in a specific folder are converted and displayed on the condition that the slide show mode is set, and the images are converted and displayed in the oldest or newest order. Any of the images may be randomly converted and displayed.

B. Here, a modification of the embodiment of the present invention will be described.
FIG. 12 is a conceptual diagram showing a folder structure of the image display device according to this modification. In the first embodiment, as shown in FIG. 5, a folder for each holder is formed by a personal identification code. On the other hand, in this modification, as shown in FIG. 12, a folder is formed and stored in the internal memory 14 for each of a plurality of memory cards.

  Currently, there are many cases where a camera SD card, a mobile phone mini SD card, a micro SD card, etc. are kept as they are, and it is difficult to know which one is. Even when a plurality of SD cards are used by a plurality of cameras, there is a case where it is not possible to know which SD card is shot with which camera and what is recorded.

  Therefore, as shown in the flow of FIG. 8, only by inserting the memory card 60 into the image display device 1 without performing any special operation, for example, the SD card (1) F11 of company A, the SD card (2 of company A) ) F12, company B SD card (1) F13, mobile phone micro SD card F14,... Company A and Company B are the names of cameras or mobile phones. Of course, the owner is clarified by attaching a personal identification code by face recognition. That is, if the father who inserted the SD card (1) is the father, the owner of the folder F11 is the father.

  In other words, as in the embodiment, if the memory card 60 is inserted into the image display device 1 without any special operation and the image is stored, a folder for each card can be automatically created. Is preferred.

  In FIG. 12, the lower folder stores an image processed in some form. For example, the folder F15 is a picture-converted image, the folder F16 is an image with a secret flag set, the folder F17 is a corrected image, and the folder F18 is a folder in which a favorite image is stored.

  Also in this modified example, the person who inserted the memory card can be identified by face recognition, so these folders may be provided as subfolders in the individual folders in FIG.

C. Next, an image distribution system according to an embodiment of the present invention will be described.
FIG. 13 is a block diagram illustrating an example of a content distribution service via a network according to the image distribution system according to the present embodiment. 2 corresponds to the image display device in FIG. 2, 520 corresponds to the network service site in FIG. 3, and 530 corresponds to the distribution content site.

  Content is distributed from the distribution content site 530, and is composed of a plurality of still image data, telop character data, and audio data as shown in FIG. These contents are basically placed in the content server 524 from the distribution content site 530. This is displayed on the liquid crystal display panel 3 of the image display device 1. Only still images can be displayed, telop characters can be played on it, and voice and music can be played.

  FIG. 14 is a conceptual diagram for explaining analysis of log information, which is a feature of the present embodiment. The CPU 11 analyzes the image of the user (browser) captured by the image sensor 8 and calculates the viewing angle information and distance information of the viewer who is browsing the image displayed on the liquid crystal display panel 3. As described with reference to FIG. 4, the number of browsing times of the viewer can be counted for each image or for each content by face recognition. Here we introduce the concept of interest index.

  In FIG. 14, the CPU 11 determines the angles θ1, θ2, and θ3 between the viewer and the image display device 1 from the imaging result of the image sensor 8, and distances L1, L2, and L3 from the viewer with respect to the image display device 1. Judging. Then, the degree of attention of the content is analyzed based on the angle and the distance, and is reflected in the log information as an interest index. Various interest indices can be acquired by recognizing the distance, angle, and movement of the viewer's face and the liquid crystal display panel 3 in addition to the browsing time and the number of browsing times.

  The movement with respect to the liquid crystal display panel 3 includes, for example, a change of the viewing angle from the viewing angle θ1 to the angle θ3 with respect to the liquid crystal display panel 3 when the user is paying attention to the content by face recognition, 3 is converted into an algorithm and reflected in the log information as an index of interest in content.

  In addition, family face recognition may be performed in advance, and information on what content and who has viewed what content may be reflected in the log information. Alternatively, family facial expressions may be recognized and information such as reactions (laughing, interested, surprised) when viewing the content may be reflected. Furthermore, the staying status of the family at the installation location of the image display device 1 such as one day, one week,... May be reflected in the log information. Further, not only the recognition information but also an operation such as whether it is registered as a favorite or displayed in full screen may be reflected as an interest index.

  FIG. 15 is a flowchart showing a schematic operation of log recording in the image display apparatus 1 according to the present embodiment. On the premise that the image display device 1 is connected to the network by a wireless LAN or the like, the CPU 11 enters the content display mode (step S90). The content display mode is a mode for receiving and displaying content distributed from the distribution content site 530, and includes, for example, a weather forecast channel, a fashion channel, a dressing proposal channel, a stock price channel, a live camera channel, and so on. As described with reference to FIG. 13, the content information is temporarily placed in the content server 524 of the network service site 520, and is downloaded from there to the image display device 1 via the communication control unit 30.

  Therefore, the CPU 11 causes the user to select a desired channel (step S92). When the user selects a channel, a predetermined page of the selected channel is displayed (step S94). The image pickup device 8 basically performs continuous shooting, and the face recognition engine 100 recognizes the face of the operator (browser) (step S96). Then, CPU11 calculates | requires the angle from the perpendicular | vertical direction (front side seeing from a screen) which shows the distance to a browser, and a viewer's browsing direction by a calculation (step S98, step S100). Further, when the recognized face moves, the moved distance and angle are detected (step S102). As described with reference to FIG. 14, if the browsing direction of the viewer changes from the angle θ <b> 1 to the angle θ <b> 3, it is considered that the interest index is high because it has moved from the diagonal to the front. Further, when the distance between the image display device 1 and the viewer changes from the distance L3 to the distance L1, it is considered that the interest index is high because it has approached the screen.

  The CPU 11 calculates the interest index by combining these pieces of information (step S104). There are various methods of calculating the interest index. For example, the interest index for the content of “dad” with the personal identification code “1001” is “number of times seen”, “time seen”, “distance seen”, It depends on “viewing angle”, “movement situation when viewing”, “favorite registration operation”, and “full-screen display operation”. This is recorded in the reaction log memory 300 as log information (step S106).

  In this state, it is determined whether or not any operation has been performed (step S108). For example, when another channel selection operation is performed, the process returns to step S92 (A), and another screen of the same channel is displayed. If the designated operation is performed, the process returns to step S94 (B). When any other operation is performed, the process proceeds to a necessary processing flow according to the operation (C in step S110).

  This log information is important information for the network service site 520 as to what kind of content is to be purchased and what kind of display is to be performed. For the distribution content site 530, the amount of charge is determined in terms of content creation. It will be important information for. Furthermore, it is possible to recognize the viewer's face and automatically display content of interest to that person.

  FIG. 16 is a conceptual diagram showing an example of a file structure of content distributed from the distribution content site 530 and temporarily stored in the content server 524 of the network service site 520 in the present embodiment. C1 is a header in which data indicating the characteristics of the content file itself such as distribution company information, data type, and data size is written. C2 is an application, and a program when this content is moved by the program is written. For example, Adobe Flash (trademark of Adobe), JAVA (trademark) (trademark of Sun Microsystems), etc. C3 is a data portion that is actually displayed that is the main content. C4 is audio data, C5 is character data including a telop as shown in FIG. 13, C6 is part data used by the application C2, C7 is distribution information including a distribution destination, distribution time, etc., and C8 is Billing information in the case of paid content, C9 is advertising information when an advertisement is included.

  C10 is the viewer information including the personal identification code that is the recognition result as described above, and C11 is “the number of times of viewing”, “the time of viewing”, “the distance of viewing”, and “the angle of viewing” as described above. , Interest index information calculated from “moving situation when viewing”, “favorite registration operation”, and “full screen display operation”. The viewer information C10 and the interest index information C11 are stored in the reaction log memory 300 together with a header C1 that specifies the content.

In the present embodiment, authentication by the image sensor is performed. However, fingerprint authentication or vein authentication technology may be provided on the touch panel 5 or the button unit. Examples of log information analysis by fingerprint authentication or vein authentication include the following.
For example, a button for personal assignment is prepared to make information such as the channel selection time zone, whether the advertisement window is closed, whether more detailed information has been viewed, whether more detailed information has been downloaded, and guidance information issued by the content distribution side Information such as the selection status of the window, who pressed the still image button and the download button for what content, and the like can be taken into the interest index and analyzed as log information.

Next, an example of performing picture conversion according to environmental information will be described.
Painting conversion is an oil painting style, watercolor style, oil painting style, pastel style, colored pencil style, crayon style, illustration style, point style, airbrush, silk screen style, embroidery picture, etc. It is converted into a so-called painting style such as wind and collage. The style (~ tone) and style (~ wind) have the same meaning, and the style is more pictorial, but there is no technical difference.

  Image processing technology basically adjusts and combines various effect processing (filter processing) parameters known for photo retouching software, etc., so that the image looks like a painting.

  A parameter is an element for applying an effect process to a pixel. That is, a pixel is generally expressed by gradations of a plurality of bits for each of RGB, but is an element for performing an operation on the bit data. Specific examples are shown below. For example, when red is emphasized, the above-mentioned “2”, “0.9”, R × 2, G × 0.9, B × 0.5, etc. “0.5” is a kind of parameter. Alternatively, the calculation elements are programmed in advance, and R × 1.1 when the red emphasis level is 1, R × 1.2 when the emphasis level is 2, and R × 1.3 when the emphasis level is 3. The degree of emphasis when performing simple calculations is also a type of parameter.

  In addition, a predetermined calculation may be performed between the target pixel and adjacent pixels. For example, the pixel P1 (RGB), P2 (RGB), P3 (RGB), P4 (RGB), P5 (RGB), P6 (RGB), P7 (RGB), P8 (RGB) around the target pixel P5 (RGB) , P9 (RGB) are aligned vertically and horizontally, P5 (R) = P5 (R) = P1 (R) × n1 + P2 (R) × n2 + P3 (R) × n3 + P4 (R) × n4 + P5 (R) The calculation of * n5 + P6 (R) * n6 + P7 (R) * n7 + P8 (R) * n8 + P9 (R) * n9 is performed, and the same calculation is performed for G and B. n is a parameter, and different effect processing can be performed by changing this numerical value (coefficient).

  In the effect process and the picture conversion process, complicated arithmetic processes for such pixels are programmed in advance.

  Examples of effect processing include, for example, texture processing that maps a texture to an image to give a special texture, and the image is classified into a texture portion and a flat portion such as a contour portion and a fine pattern, and each is appropriately processed. Resolution processing that enhances texture and resolution, HSV processing that categorizes and adjusts colors into three elements: Hue, Saturation, and Value (Value), and R (Red) G (Green) B for images (Blue) RGB processing for adjusting the degree of each color, RGB exchange processing for exchanging in the direction of R → G → B, edge extraction processing for applying a filter called a Laplacian filter, intermediate density extraction processing for applying a filter called a median filter, adjacent RGB histograms of the pixels to be extracted are extracted, and the histograms between the pixels are distributed as appropriate to correct the contrast and subtract the image histogram. Equalization processing, gamma correction processing that adjusts intermediate brightness while maintaining bright and dark areas, shadow processing that brightens dark areas of images and darkens bright areas, and RGB values for each pixel There is a solarization process that inverts the RGB value when the brightness is above a threshold value, a noise addition process that draws dots randomly, generates noise, and adjusts the amount and color of noise.

There is also an effect process that processes the touch (brush) differently.
Specifically, pixels having high correlation are collected from pixels constituting image data on the basis of color or the like to form a group. Subsequently, for each group of pixels, for the same group of pixels, the color is replaced with the representative color of the group. A group of pixels in which the colors are replaced with the representative colors in this way form each brush stroke. According to such image processing, by changing the correlation of the pixels collected as a group and the shape (length (distance), flatness) of the group composed of pixels of the same color (representative color) The formed brush can be changed, and as a result, the tone of the image represented by the image data can be changed to various painting tone. For each image tone, an optimum combination of parameters such as the degree of correlation used in each process, the length representing the shape of the group, and the flatness is set, and this information is stored in the parameter memory 410. The painting conversion engine 200 changes the image style based on the information stored in the parameter memory 410.

  Changing each of the plurality of pieces of image data to a different stroke can be realized by adjusting the shape of the group in which the pixels constituting the stroke are collected, for example, the flatness of the group when changing the image tone. When the flatness of the group composed of pixels of the same color representing the brush stroke is increased, the brush stroke becomes thick, and as a result, the touch of the image is displayed roughly. When the flatness of the group composed of pixels of the same color is reduced, a small brush can be created, and as a result, the touch of the image is displayed finely.

  FIG. 17 shows an example of a group of pixels representing a brush generated in this way. For example, as shown in FIG. 17A, when the flatness of a group composed of pixels of the same color representing the touch is increased, the touch becomes thicker, and as a result, the touch of the image is displayed roughly. As shown in FIG. 17C, when the flatness of the group composed of pixels of the same color is reduced, a small brush can be created, and as a result, the touch of the image is displayed finely. The group shown in FIG. 17B represents a standard stroke.

FIG. 18 is a flowchart showing an outline of picture conversion. First, an image to be converted into a picture is read from the memory card 60 into the RAM 13 (step S202). In order to adjust R (red), G (green), and B (blue) for each pixel, it is converted into bitmap data (step S204).
Then, which image tone is desired is selected (step S206). Since various parameters are programmed in advance for each image adjustment, the parameters are read from the parameter memory 410 and set (step S208). Then, conversion processing is performed on the target image with the parameters (step S210).

  For example, in the case of a watercolor style, an RGB histogram of adjacent pixels is extracted, and filtering is performed so that the distribution parameter of the histogram is finer on the minimum density side and coarser on the maximum density side. Furthermore, a blurring filter called a Gaussian filter is applied to the pixels to add details with a small number of lines to create a hazy image tone.

Next, the environment information collected by the environment information engine 400 is read (step S212), and a predetermined conversion process is performed on the parameters set in step S208 according to the environment information (step S214). That is, the image tone is further changed according to the environment information. Then, a picture conversion process is performed according to the changed parameter (step S216). Thereby, even if it is an image which image | photographed the same place with the same camera, the image of a different image tone can be obtained with the environment of the place where the camera is installed. An example of changing the image tone according to the environmental information will be described later with reference to FIGS. Note that the painting conversion process in step S210 may be omitted if the painting conversion image before reflecting the environment information is not necessary.
The picture converted in step S216 is converted into JPEG data, compressed (step S218), and stored in the internal memory 14 or the memory card 60 (step S220).

  Hereinafter, an example in which the image tone is changed according to the environment information will be described. FIGS. 19A and 19B show examples of environment information generated by the environment information engine 200. FIG. One of the environments indicated by the environment information is, for example, the position of the distribution content site 530 (position in terms of geographical meaning). (In the figure, the position in the environmental information is expressed as environmental data). The position is represented by a combination of latitude and longitude, a postal code, or the like. Alternatively, it may be represented by an address, a telephone number, a fixed IP address of an access point for connecting to the Internet 500, a delivery center code managed by a delivery company or the like. The date and time may be expressed by date and time, or by a time difference from a certain reference point (for example, the location of the building where the environmental information server 526 is installed or the reference point of Greenwich Mean Time GMT). (In the figure, date and time, weather, temperature, humidity, wind speed, etc. as environmental information are described as feature data).

  The environment information engine 400 acquires the environment information at a regular timing and updates it appropriately. FIG. 19B is a diagram illustrating an example of environment information after the environment information of the distribution content service site 530 at the position illustrated in FIG.

FIG. 20 shows a “conversion algorithm” which is one of the parameters.
For example, when information indicating “clear” is sent from the environment information server 526 of the distribution content site 530, the CPU 11 causes the image data received from the environment information server 526 to become an image drawn with a colored pencil. Effects processing.
The weather classification method and the conversion algorithm classification method are arbitrary. Also, an embodiment in which the association between the weather and the conversion algorithm is arbitrarily changed can be adopted.

FIG. 21 shows “deformation” which is one of the parameters.
For example, when information indicating “temperature less than 10 ° C.” is sent from the environment information server 526, the CPU 11 becomes an image in which the feature portion is exaggerated to a very moderate degree with respect to the image data received from the distribution content site 530. Apply effect processing as follows.
The method of classifying the temperature and the method of classifying the degree of deformation are arbitrary. Further, it is possible to adopt an embodiment in which the association between the temperature and the degree of deformation is arbitrarily changed.

FIG. 22 shows “brush thickness” which is one of the parameters.
For example, when information indicating “the wind speed is less than 1 meter” is sent from the environment information server 526, the CPU 11 causes the contour lines and feature lines included in the image to be thin with respect to the image data received from the distribution content site 530. Effects processing.
The method of classifying the wind speed and the method of classifying the thickness of the brush are arbitrary. In addition, it is possible to adopt an embodiment in which the association between the wind speed and the thickness of the brush is arbitrarily changed.

  FIG. 23 shows that weather information is collected from information such as atmospheric pressure, humidity, and illuminance obtained by the sensor 40, or that telephoto information from other distribution content sites 530 is acquired, and painting conversion is performed according to the environmental information. An example of changing the algorithm (painting) and “brush thickness” which is one of the parameters will be shown. For example, on a fine day, it is converted into a color pencil drawing style with a very thin brush thickness, and on a rainy day, it is converted into a pastel tone with an ordinary brush thickness.

  FIG. 24 shows an example in which the atmosphere of a painting is changed according to time information. An example of changing the tone of a material image to be picture-printed by adjusting various parameters is shown. For example, between 00:00 and 02:00, the tone is converted as if it was drawn on smooth paper, and 02 : 00 to 04:00: The tone is converted “as if it was drawn on paper with coarse eyes”. Since this material image is not precisely defined and has a large portion depending on the sensibility of the author, parameters are set in advance when creating the algorithm, and a conversion atmosphere is prepared.

  As described above, according to the embodiment of the present invention, the tone of the display image can be changed according to the environment information received from the distribution content site 530.
