According to the technique described in Patent Document 1, the content recorded in the past is customized and reproduced according to the environment at the time of reproduction. That is, in the technique described in Patent Document 1, the information of the time (past) when the content has the content is not referred to when the content is reproduced.

Therefore, for example, when recorded content that is captured in the winter season and reflects a star shining in a clear night sky is played back in the summer, the technique described in Patent Document 1 provides the recorded content with a summer environment. It is also envisaged that a corresponding correction will be applied. As described above, when the correction is performed according to the summer environment, the atmosphere of light emitted by the stars shining in the winter sky may not be easily transmitted to the viewer of the reproduced content.

Further, for example, when the recorded content recorded in a famous concert hall is played back at the viewer's home of the content, the technique described in Patent Document 1 responds to the recorded content according to the environment of the home. It is also envisaged that a correction will be made. In this case, there is a possibility that viewers of the reproduced content may not be able to obtain the realistic sensation obtained when viewing the concert hall.

When the content is not corrected as in the technique described in Patent Document 1, the content recorded in the past is reproduced as it is at the time of recording. Therefore, for example, content that does not fully reflect the situation at the time of recording, such as photographs where the vividness that the photographer saw and felt was not reproduced much, is played back as it is without correction, Appreciated by the viewer. In this case, the viewer cannot feel the situation at the time of recording the content through the reproduced content.

The present invention has been made in view of such a situation. An object of the present invention is to allow a viewer of content to more effectively feel the situation at the time when the content was recorded, through the reproduced content.

In order to solve the above problems, a content processing device that reflects one aspect of the present invention includes a first network control unit, an adjustment content determination unit, and an adjustment unit. The first network control unit controls a data transmission/reception operation performed with a reproduction device that reproduces content. The adjustment content determination unit determines the adjustment content of the adjustment that reproduces or emphasizes the situation at the time of generating the content, based on the accompanying information of the content at the time of generating the content. When the first network control unit receives the reproduction request for the content transmitted from the reproduction device, the adjustment unit adjusts the content according to the adjustment content determined by the adjustment content determination unit, and adjusts the adjusted content. , To the playback device via the first network control unit.

In the present invention, the content for which the content processing device has been adjusted to reproduce or emphasize the situation at the time of generating the content is transmitted to the reproduction device and reproduced by the reproduction device. Therefore, according to the present invention, the viewer of the content can more effectively feel the situation at the time when the content was recorded through the reproduced content.

The content adjustment target is a target to be adjusted by the content data adjusting unit 27, and indicates a location in the content where the content adjustment should be performed, a content type, or the like.

When the content is an image, the content data analysis unit 25 can grasp the content, for example, by pattern matching between an image forming the content and a template (not shown). Further, for example, regardless of whether the content is an image or a sound, the content data analysis unit 25 grasps the content of the content by analyzing a character string describing the content of the content described around the content. can do. The character string describing the content may be a character string described around access information (URL (Uniform Resource Locator) or the like) to the storage location of the content, not around the content itself.

In addition, the content data analysis unit 25 determines the content adjustment content by referring to the content adjustment content table T1 stored in the storage unit 29 based on the content adjustment target and the acquired content incidental information. .. The content adjustment content is an adjustment content that makes the content more attractive, and more specifically, an adjustment content that reproduces or emphasizes the situation at the time of generating the content.

In the content adjustment content table T1, the content adjustment content, the content accompanying information, and the content adjustment target are managed in association with each other. In the present embodiment, an example in which a content adjustment content table T1A (see FIG. 5) and a content adjustment content table T1B (see FIG. 6) are provided as the content adjustment content table T1 is shown. The content adjustment content table T1A is a table that has, as content accompanying information, information on the recording (generation) time of content. The content adjustment content table T1B is a table having, as the content accompanying information, information of a character string that describes the content of the content existing around the content.

In the present embodiment, an example in which two types of content adjustment content tables T1 are provided is given, but the present invention is not limited to this. Only one type of content adjustment content table T1 may be provided, or two or more types of content adjustment content table T1 may be provided. When a plurality of types of content adjustment content tables T1 are provided, the priority order is set for each table, and then the content data analysis unit 25 may refer to the tables in descending order of priority. Good.

In addition, the content data analysis unit 25 determines the adjustment amount of the adjustment content for the determined content with reference to the content adjustment amount table T2 stored in the storage unit 29. A configuration example of the content adjustment amount table T2 will be described in detail with reference to FIGS. 7 and 8 described later.

Further, the content data analysis unit 25 sets the adjustment range of the adjustment amount in the content adjustment amount table T2 by evaluating the content of the content. The content data analysis unit 25 sets, for example, the upper limit of the content adjustment amount as the adjustment amount setting range. The setting of the adjustment range is performed for the purpose of preventing the contents of the adjustment from being overkill.

For example, when the content is an image, the content data analysis unit 25 measures the brightness of the image and sets the upper limit of the adjustment amount when the content (image) is adjusted based on the measured brightness information. Set. Further, for example, when the content is voice, the content data analysis unit 25 measures the noise amount in the audible sound range included in the voice, and adjusts the content (voice) based on the information of the measured noise amount. Set the upper limit of the adjustment amount when it is performed.

Further, the content data analysis unit 25 analyzes the evaluation result of the content received by the user from the reproduction device 1, and updates the value of the corresponding item in the content adjustment amount table T2 based on the analyzed result.

The content data management unit 26 receives the analysis result by the content data analysis unit 25 and updates the adjustment target, adjustment content, and adjustment amount in the content adjustment content table T1 and the content adjustment amount table T2 for each content based on the analysis result.

The network control unit 28 controls various data transmission/reception operations performed with the playback apparatus 1 via the network N. The data transmitted/received to/from the playback device 1 includes, for example, a content playback request, adjusted content data, and a user evaluation result.

The storage unit 29 is composed of, for example, an HDD (Hard Disk Drive), and stores the content data acquired by the content data analysis unit 25 and associated information (not shown) of the content data in association with each other. Each content included in the content data is managed by being given a content ID for managing the content, for example. It should be noted that what is added to the content for managing the content is not limited to the ID, and may be another one such as a URL as long as it functions as an identifier capable of specifying the content.

Further, the storage unit 29 stores a content adjustment content table T1 and a content adjustment amount table T2.

[How to get the string around the content]
Next, with reference to FIG. 4, a method of acquiring the character string around the content by the content data analysis unit 25 will be described. FIG. 4 is a diagram showing an example of a method of acquiring a character string around the content by the content data analysis unit 25.

FIG. 4 shows a blog Bg including an aurora photograph as the content Cn. The content data analysis unit 25 searches a character string surrounding the content Cn for a character string that describes the content Cn. In the example shown in FIG. 4, the content data analysis unit 25 searches, for example, a range Ar in which a sentence to which the title “Travel in the Arctic Circle” is attached is arranged around the content Cn. Then, from among the characters within the range Ar, the character “shining” (the character in the portion surrounded by the dashed rectangular frame) that is considered to describe the aurora photograph as the content Cn is acquired. To do.

The content data analysis unit 25 determines the content adjustment content by referring to the content adjustment content table T1 based on the acquired “shining” character string and the content copied to the content Cn, that is, “aurora”. To do. After the content adjustment content is determined, the content adjustment amount table T2 is referenced to determine the adjustment amount corresponding to the content adjustment content.

Note that the content data analysis unit 25 determines that the content is added when the content is generated even when the character string describing the content existing around the content is added later to the content. It is regarded as the information provided. This is because the character string added later to the content is also considered to represent the content when the content was generated.

[Content adjustment content table configuration]
Next, a configuration example of the content adjustment content table T1 will be described with reference to FIGS. FIG. 5 is a diagram showing a configuration example of the content adjustment content table T1A in which the adjustment target and the adjustment content of the content corresponding to the information of the recording time of the content are described. FIG. 6 is a diagram showing a configuration example of the content adjustment content table T1B in which the adjustment target and the adjustment content of the content corresponding to the information of the character string describing the content are described.

The content adjustment content table T1A shown in FIG. 5 is a table that the content data adjustment unit 27 refers to when determining the content adjustment content based on the information on the recording (generation) time of the content. The content adjustment content table T1A has items of “content type”, “content adjustment content”, “content recording time”, and “adjustment target”.

In the item of “content adjustment content”, contents of adjustment performed on the content by the content data adjusting unit 27, such as “saturation increase”, “contrast increase”, and “emphasize so as to make a sharp sound”, are included. The information shown is stored. The “content type” item stores information indicating the type of content such as “image type” and “sound type”. The "content recording time" item stores information indicating the time when the content such as "September to November", "prewar", and "winter" was recorded. The “adjustment target” includes a part of the content to be adjusted by the content data adjusting unit 27 such as “autumn leaves, whole (landscape)”, “monochrome movie”, “voice of crane”, content type, and the like. Information is stored.

For example, as a result of the analysis by the content data analysis unit 25, the content is an image content in which “autumn leaves” specified in the “adjustment target” item is copied, and the content recording time is “September to November”. Suppose it turns out. In this case, in the content adjustment content table T1A, the adjustment content of the content of “saturation up” is associated with “autumn leaves” that is the “adjustment target”. Therefore, the content data adjusting unit 27 adjusts the content so as to increase the saturation of the portion where "autumn leaves" appears in the image that is the content.

Further, for example, as a result of the analysis by the content data analysis unit 25, the content is “AM radio content” specified in the item “adjustment target”, and the content recording time is “before wide FM start”. Is found. In the content adjustment content table T1A, the content of adjustment of "monaural and frequency band suppression" is associated with "AM radio content" that is "adjustment target". Therefore, the content data adjustment unit 27 sets the reproduction method of the audio that is the “AM radio content” to “monaural” and adjusts the frequency band of the audio as the adjustment of the content.

The content adjustment content table T1B illustrated in FIG. 6 is a table that the content data adjustment unit 27 refers to when determining the content adjustment content based on the information of the character string that describes the content existing around the content. The content adjustment content table T1B has items of “content type”, “content adjustment content”, “character string to describe”, and “adjustment target”.

The items of “content type”, “content adjustment content”, and “adjustment target” are the same as those in the content adjustment content table T1A shown in FIG. In the "character string to describe" item, the content of the character string that describes the content, such as "Daytime shooting", "Beautiful", "Midsummer sun", "Transparent", "Treble sounds", etc. Is stored.

For example, as a result of the analysis by the content data analysis unit 25, the content is an image content in which “Aurora” specified in the item of “adjustment target” is copied, and the content around the content is described as “shining”. It turns out that In the content adjustment content table T1B, the “aurora” that is the “adjustment target” is associated with the content adjustment content of “brightness up”. Therefore, the content data adjusting unit 27 adjusts the content so as to increase the brightness of the portion where "Aurora" appears in the image which is the content.

Further, for example, as a result of the analysis by the content data analysis unit 25, it is found that the character string describing the content around the content is “transparent”, and the content is the audio content. In the content adjustment content table T1B, the character string “transparent” is associated with the content adjustment content of “his noise removal”, and the adjustment target is described as “whole”. Therefore, the content data adjusting unit 27 performs, as the content adjustment, an adjustment for removing the hiss noise with respect to the entire voice in which the character string “transparent” is described.

In this way, in the content adjustment content table T1 (T1A and T1B), the saturation of the image of autumn leaves taken in autumn, the brightness of the image of aurora taken in winter, etc. are increased. , The content of adjustment for reproducing or emphasizing the situation at the time of content generation is set.

[Content adjustment amount table configuration]
Next, a configuration example of the content adjustment amount table T2 will be described with reference to FIGS. 7 and 8. FIG. 7 is a diagram showing a configuration example of the content adjustment amount table T2v that is referred to when the type of content is an image. FIG. 8 is a diagram showing a configuration example of the content adjustment amount table T2a that is referred to when the type of content is audio.

First, the content adjustment amount table T2v will be described with reference to FIG. The content adjustment amount table T2v illustrated in FIG. 7 has items of “generation time information”, “adjustment target”, “adjustment content”, and “adjustment amount for original image”.

The “generation time information” has two items, “generation time” and “character string describing adjustment target”. The “generation time” stores information indicating the time when the content is generated (photographed) such as “September to November” and “prewar”. In the "character string that describes the adjustment target" item, a character string that describes the content (adjustment target) that exists around the content, such as "daytime shooting", "shining", and "the midsummer sun" The contents of are stored.

In the item of “adjustment target”, information indicating a target to be adjusted by the content data adjusting unit 27 (see FIG. 3) such as “autumn leaves”, “landscape”, “whole”, “aurora”, “flower”, etc. Is stored. “Whole” indicates that the adjustment target is the whole, not a part of the content.

The items of “adjustment content” (hereinafter, also referred to as “adjustment item”) include “A lightness”, “B saturation”, “C red emphasis”, “D skin color correction”, and “adjustment”. The items of "E contrast" and "F scratch noise addition" are stored. In each adjustment item, a circle mark is attached to the adjustment content to be implemented.

The item “adjustment amount for original image” stores the adjustment amount of the adjustment performed for each adjustment target. For example, for each of the adjustments of “B saturation” and “C red emphasis” performed on the adjustment target “autumn leaves”, “B: 2 times” and “C: 1.5 times” are respectively set. The adjustment amount is set.

For example, it is assumed that the time when the content is generated (captured) is “September to November” and the adjustment target is “autumn leaves”. In this case, the content data adjusting unit 27 makes an adjustment to double the saturation and to emphasize the red color by 1.5 times with respect to the place where the autumnal leaves are reflected in the content.

Further, for example, it is assumed that the character string that describes the content to be adjusted is “beautiful” and the adjustment target is “landscape”. In this case, the content data adjusting unit 27 adjusts the saturation of the portion of the content where the landscape is shown to be doubled.

Next, the configuration of the content adjustment amount table T2a referred to when the type of content is audio will be described with reference to FIG. The content adjustment amount table T2a has the same items as the content adjustment amount table T2v.

The difference between the content adjustment amount tables T2v and T2a is the item of adjustment content. In the content adjustment amount table T2a that is referred to when the content type is audio, the adjustment contents are "A sharpness enhancement", "B monaural", "C frequency limitation", "D hiss noise deletion", and "E treble enhancement". Each item of "" and "F acoustic characteristic effect" is provided. Then, also in the content adjustment amount table T2a, a circle mark is added to the adjustment content to be implemented in each adjustment item.

For example, it is assumed that the time when the content is generated (recorded) is “winter” and the adjustment target is “voice of crane”. In this case, the content data adjusting unit 27 performs an adjustment to double the "sharpness" with respect to the voice of the crane.

As described above, the adjustment content and the adjustment amount described in the content adjustment amount table T2 (T2v, T2a) are updated by the content data analysis unit 25 based on the user evaluation result of the content received from the playback device 1. ..

The evaluation of the content is received from the user via the operation input unit 11 of the reproducing apparatus 1 after the content adjusted by the content data adjusting unit 27 is reproduced by the content data reproducing unit 15 of the reproducing apparatus 1.

To accept the evaluation of the content, after the reproduction of the content is completed, each of “A” to “F” in the adjustment content of the content adjustment amount table T2 shown in FIGS. 7 and 8 is displayed on the screen of the display unit 12 of the reproduction apparatus 1. This can be done by displaying adjustment items and their evaluation options. In this case, the user as a viewer of the content is asked to input an evaluation of, for example, 10 paragraphs for each adjustment item.

Further, in the evaluation of the content in which the “color”, the “contrast” and the like have been adjusted, the evaluation options may be simplified. For example, for the image content of autumn leaves after the adjustment of red emphasis has been performed, the user can select the one corresponding to the evaluation result from the three options “insufficient”, “appropriate” and “excessive”. You may let me.

Further, when reflecting the evaluation result of the content on the adjustment content (adjustment item), the content data analysis unit 25 not only adjusts one adjustment item but also the adjustment amount of other adjustment items related to the adjustment item, You may update at the same time. For example, when it is determined that the brightness value is updated based on the evaluation result of the content, not only the brightness but also the saturation value may be updated.

The content data analysis unit 25 repeatedly updates the adjustment content and the adjustment amount based on the user's evaluation result in this way, thereby obtaining an average adjustment amount preferred by all users who have evaluated each content. be able to.

Note that the content adjustment content (adjustment items) is not limited to the examples described with reference to FIGS. 5 to 8. If the content type is an image, the content adjustment content may be any content as long as it is an adjustment that changes at least one of the image shape, color, size, and image quality. Good. When the type of content is a moving image, the number of frames per second may be reduced to make adjustments to reproduce the situation at the time of recording.

Further, when the content type is audio, adjustment may be performed to change the volume and/or sound quality with respect to time transition within a frequency band including audio, including adjustment of each of the right channel and the left channel. ..

[Content processing method by content processing system]
Next, a content processing method by the content processing system 100 will be described. First, with reference to FIG. 9, a content processing method by the playback device 1 that constitutes the content processing system 100 will be described. FIG. 9 is a flowchart showing an example of the procedure of the content processing method by the playback device 1.

When it is determined in step S6 that the acceptance of the evaluations for all the evaluation items is not completed (NO in step S6), the CPU 10 determines whether a time-out has occurred (step S7). In step S7, the CPU 10 determines whether or not there is an unevaluated item at the stage when the limit set for the time for accepting the evaluation is exceeded.

When it is determined in step S7 that the timeout has not occurred (NO in step S7), the CPU 10 repeats the determination in step S6. That is, it is determined whether the evaluations for all the evaluation items have been received. On the other hand, if it is determined in step S7 that the time-out has occurred (YES in step S7), the CPU 10 determines the content ID assigned to the content and the evaluation result by the user via the network control unit 16. It is transmitted to the processing server 2 (step S8). Here, the evaluation result transmitted to the content processing server 2 is the evaluation result input before the timeout.

When it is determined in step S6 that the acceptance of evaluations for all evaluation items is completed (YES in step S6), the CPU 10 performs the process of step S8.
