Description

  The present invention relates to a content reproduction apparatus, a content reproduction method, a content reproduction program, and a recording medium.

  In particular, the present invention relates to a content reproduction apparatus, a content reproduction method, a content reproduction program, and a recording medium for reproducing digital content data such as comics.

  A comic is a combination of pictures, lines, etc., and one display data is drawn inside one “frame”, that is, inside a frame line. Readers can develop and read the story by reading the “frame” pictures and lines in order.

By the way, comics were printed on paper and published as magazines and books. However, since comics are mainly pictures, they can be stored as image data and displayed on a display device. Furthermore, by using an apparatus capable of reproducing sound as well as displaying images, an invention for reproducing events such as sound effects registered for each “frame” while displaying images one by one in order Is disclosed (for example, Patent Document 1).
JP 2002-279396 A (published September 27, 2002)

  However, the invention of Patent Document 1 has a problem that a predetermined event needs to be registered for each “frame”. In addition, if the event playback function varies depending on the hardware configuration of the device, such as whether audio playback is performed, whether there is a vibration function, or whether the light is lit, the size of the content must be registered because events corresponding to all configurations must be registered. The problem that it increases will arise. Furthermore, in an apparatus that does not have a function for reproducing a registered event, there is a problem that the registered event is not transmitted to the reader and is wasted.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to output an event corresponding to the content when reproducing digital content that does not have event operation information. An object of the present invention is to provide a content reproducing apparatus capable of performing the above.

  In order to solve the above-described problem, the content reproduction apparatus according to the present invention provides a plurality of display objects including at least one of image data, character data, and accompanying information indicating display characteristics of the image data or the character data. A content playback apparatus that plays back digital content composed of data, and specifies an event operation for outputting at least one of the image data, the character data, and the accompanying information as the display data Extraction means for extracting as event specifying information, storage means for storing event correspondence information indicating a correspondence between the event specifying information and the event action, and the display based on the event specifying information and the event action. Provided with event determining means for determining an event operation to be output when data for reproduction is reproduced It is characterized by a door.

  According to said structure, an extraction means extracts event specific information from display data, an event determination means reads event corresponding information from a memory | storage means, and determines event operation output from event specific information and event corresponding information. Here, in the event correspondence information, the expression contents in the display data predicted from the event identification information, for example, the strength of the scene, the shock level, and the expression corresponding to the expression contents are output using various hardware. Event operations such as vibration function and blinking illumination are recorded in association with each other, so when playing digital content that does not have event operation information, an appropriate event according to the content of the digital content to be played back The operation can be output.

  The display data is defined here as a unit for executing one event operation. The display data is appropriately set according to the interval at which the event operation is executed. As a specific example, for example, when the digital content is digital manga, the display data described above may be one “frame” or set in units of “balloons” that are frame lines surrounding the lines. May be. In general, in a manga, one scene is drawn inside one “frame”, that is, inside a frame line. Readers can develop and read the story by reading the “frame” pictures and lines in order. The words are usually written in a frame called “balloon”. When the display data is defined as “frame”, the number of event operations that can be output while one “frame” is reproduced is one. When the display data is defined as “balloon”, the event operation can be output for each “balloon”.

  The image data may be, for example, all images except characters and “balloons” included in “frame”, or “effect line” “concentrated line” “kakeami” “tone” “decorative character” It may be a figure excluding an emphasis figure such as or a manga symbol. The character data may be, for example, an ASCII code indicating a character string, or may include other decoration information related to characters such as font type / size / bold / thin / shaded / underlined / marking. May be.

  It should be noted that the data such as the image type and character decoration information exemplified above may be separated from the image data and the character data and all handled as accompanying information. Furthermore, color information such as color scheme, brightness, saturation, and hue may be used as accompanying information. The incidental information may be any information as long as it is event specifying information that is a basis for specifying the event operation. The event specifying information may be recorded in the digital content data as accompanying information, or may be recorded outside the digital content data as file management information or an external file.

  In the content reproduction apparatus according to the present invention, the extraction unit specifies an event for shape information of a frame surrounding the character data included in the display data or font information of the character data included in the display data. It is preferable to extract as information.

  Since the event specifying information is the shape of the frame surrounding the character data included in the display data, the event specifying information of the display data is determined from the shape of the frame, and thus emphasized by the shape of the frame The event operation corresponding to the displayed display data can be easily determined.

  In addition, since the event specifying information is font information of the character data included in the display data, the event data to be reproduced with the display data is determined based on the font information of the character data. It is possible to easily determine and output an event action corresponding to.

  In addition, the shape of the above-mentioned frame line appears from, for example, a line type such as a solid line, a dotted line, a broken line, and a thick line, a line formed by a line such as a circle, an ellipse, a rectangle, a polygon, a jagged shape, and a cloud shape. The shape of the part extended toward the person may be sufficient.

  For example, in the above-mentioned comic “Balloon”, the strength of emotion is often expressed by drawing in a shape according to the emotion of the speaker. By using the shape information of “Balloon” as event specifying information, the event action can be determined based on the emphasis expressed by “Balloon”. By determining the event operation according to the event specifying information, it is possible to output an event operation appropriate for display data in which “balloon” is used.

  In addition to the font type and font size, the font information may be, for example, an effect of emphasizing fonts such as bold, thin, shadowing, underlining, and marking. As the font information, information defined by conventional character input software, image creation software, DTP (desktop publishing) software, or the like may be used.

  In the content reproduction apparatus according to the present invention, it is preferable that the extraction unit extracts display size information of the image data included in the display data as event specifying information.

  Since the event identification information is the display size of the display data, the event operation is determined by the vertical and horizontal sizes of the image, so the event operation corresponding to the strength expressed by the size of the picture by the content producer is easy. Can be guessed and determined.

  The display size may be used as event specifying information by determining the display magnification based on the resolution of the image data and the display size of the display unit of the content playback apparatus that plays back digital content.

  In the content reproduction apparatus according to the present invention, it is preferable that the event operation is at least one of an image effect addition operation, an audio reproduction operation, a vibration operation, and an illumination lighting operation.

  By using the existing hardware as a content playback device, event operations according to the contents of digital content can be easily output by using the above-mentioned event operations as image effect addition operations, sound playback operations, vibration operations, and lighting operations. can do.

  Specifically, for example, when playing content on a mobile phone, PDA (personal digital assistant), portable game machine, electronic book viewer, PC (Personal Computer), etc., it corresponds to event specific information of each display data The event operation to be performed can be easily output using the existing hardware configuration.

  In order to solve the above problems, a content reproduction method according to the present invention is a plurality of displays for display including at least one of image data, character data, and accompanying information indicating display characteristics of the image data or the character data. A content reproduction method for reproducing digital content composed of data, wherein an event operation for outputting at least one of the image data, the character data, and the accompanying information as the display data is specified. Extracting the event identification information for the event, reading the event correspondence information indicating the correspondence between the event information and the event action from the storage means, and the display based on the event identification information and the event correspondence information And determining the event action that causes seed depression when playing back the data. It is characterized in Rukoto.

  According to the above configuration, the event identification information is extracted from the display data, the event correspondence information is read from the storage means, and the event action to be output is determined from the event identification information and the event correspondence information. When playing back non-digital content, an appropriate event operation according to the content of the digital content to be played back can be output.

  Each unit in the content reproduction apparatus can be executed on a computer by a content reproduction program. Furthermore, the content reproduction program can be executed on an arbitrary computer by storing the content reproduction program in a computer-readable recording medium.

  In the content reproduction apparatus according to the present invention, as described above, the extraction unit extracts the event identification information from the display data, the event determination unit reads the event correspondence information from the storage unit, and outputs it from the event identification information and the event correspondence information. Since the event action to be performed is determined, it is possible to output an appropriate event action according to the content of the digital content to be played when playing back digital content that does not have event action information.

  An embodiment of the present invention will be described below with reference to FIGS.

  FIG. 1 is a block diagram showing a schematic configuration of a main part of a playback apparatus (content display apparatus) in the present embodiment. The playback device 1 (content display device) includes a processing unit 10, a storage unit (storage means) 30, a data input unit 40, an operation input unit 50, and an output unit 60. The processing unit 10 includes a data separation unit (extraction unit) 12, an event determination unit (event determination unit) 14, an image output unit 16, an event output unit 18, an output processing unit (output processing unit) 20, and an operation processing unit 22. It has. The output unit 60 includes a display unit 62, an audio reproduction unit 64, a vibration unit 66, and an illumination unit 68. Details of each part will be described below.

  The storage unit 30 stores event correspondence information indicating correspondence between event specifying information and event operations. The event correspondence information is referred to by the event determination unit 14 of the processing unit 10 and is used to determine an event operation according to the hardware configuration of the playback device 1.

  The data input unit 40 is an input device for inputting digital content to the processing unit 10. The data input unit 40 reads the digital content stored in the recording medium and inputs it to the processing unit 10. Specifically, the data input unit 40 may be a non-volatile memory or a magnetic storage medium reader built in the playback apparatus 1, or an external storage such as a CD / MO / MD / DVD or a flash memory. It may be a media reader.

  Alternatively, the data input unit 40 may download digital content via the Internet, a public line, a LAN, and the like and input the digital content to the processing unit 10. That is, the data input unit 40 may have any form as long as it provides digital content data to the processing unit 10.

  The operation input unit 50 receives an operation input from a user and is used for controlling the reproduction of content data in the output processing unit 20. The operation input unit 50 may be an input button arranged in the playback device 1 or a connection terminal for connecting an external input interface. Alternatively, it may be a receiving unit of a remote controller using infrared rays or wireless. Any device that accepts an operation input from a user may be used.

  Next, details of processing performed by each unit of the processing unit 10 will be described. The processing unit 10 receives digital content input from the data input unit 40 and performs processing for reproducing the digital content in accordance with the operation input from the operation input unit 50. First, the digital content input from the data input unit 40 is input to the data separation unit 12.

  The data separating unit 12 separates the input digital content according to the data format, extracts necessary event specifying information, and transmits it to the event determining unit 14 and the image output unit 16. Here, the format of the digital content will be described. In the present embodiment, the digital content is described as digital comic data including image information, character information, and other accompanying information.

  In the digital comic data of this embodiment, one display data is described as one “frame”. The event specifying information of each display data will be described below as “frame information” indicating “frame” information. Each “frame” includes a “balloon”.

  “Speech” is included in “Balloon”. “Serif” drawn in “Balloon” is recorded as character data in association with “Frame number” which is an identifier of “Frame”. There may be zero or more “balloons” in each “frame”, but for the sake of simplicity of explanation, a case where one “balloon” exists in one “frame” will be described below. Do.

  The digital comic data is generated by using dedicated software for creating and editing digital comics. The data is created and managed in units of “pages”. In the following description, it is assumed that “page” includes one or more “frames”. In addition, it is assumed that one “balloon” is included in “frame”. “Frame number”, which is an identifier unique to “frame”, is assigned to “frame” in each “page”.

  In “Balloon”, “Serif” composed of one or more character strings is written. “Balloon” includes shape information for identifying the type of “balloon” as event specifying information. “Serif” includes font information of characters used as event specifying information. The font information includes size, font type, decoration information, and the like. The above font information is handled as event specifying information of each “frame”, that is, “frame information”.

  Using the digital content, the data separation unit 12 receives the digital content data from the data input unit 40, displays the image data as it is, and the event identification information used to determine the event operation to be output in the image data. To separate.

  Thereafter, the data separation unit 12 inputs the separated event specifying information to the event determination unit 14 and the separated image data, character data, and accompanying information to the image output unit 16.

  When the image data, character data, and accompanying information to be separated are recorded uniquely in the file, the data separation unit 12 may input the data as it is or separate it as one piece of image data. If not, separation may be performed by image processing, OCR (optical character reader), pattern matching, or the like. The image data, character data, and accompanying information may be input to the image output unit and event specifying information may be input to the event determination unit 14 as described above.

  The event determination unit 14 receives “frame number” that is an identifier of display data and “frame information” that is event identification information corresponding to the “frame number” from the data separation unit 12. The event determination unit 14 refers to the event correspondence information stored in the storage unit 30 based on the received “frame number” and “frame information”, and determines an event operation to be output with the “frame number”.

  In the event correspondence information stored in the storage unit 30, an appropriate event operation is recorded in association with the type of output device provided in the hardware of the playback device 1. The event correspondence information will be described later in detail.

  The image output unit 16 converts the data separated by the data separation unit 12 according to the hardware configuration of the playback apparatus 1 and inputs the converted data to the output processing unit 20. Specifically, the resolution of the image is changed according to the display performance of the display unit 62 of the output unit 60. In addition, when there are a lot of “serif” characters to be displayed, the image output unit 16 may display “serif” in addition to “frame”. Alternatively, “balloon” may be enlarged to display a larger “serif” character. Thus, the image output unit 16 performs a process of combining the processed character data with the output image.

  The event output unit 18 inputs, to the output processing unit 20, an event operation that is output simultaneously with the reproduction of display data, based on the event operation determined by the event determination unit 14. The event output unit 18 outputs one event for each “frame” when the display data is in “frame” units, and for each “balloon” when the display data is in “balloon” units.

  The operation processing unit 22 receives an operation instruction from the operation input unit 50 and controls the reproduction of digital content. Specifically, an identifier of display data to be output next is determined in response to the operation instruction, and is input to the output processing unit 20. The output processing unit 20 determines an image and event to be currently reproduced based on the “frame number” that is the identifier of the display data received from the operation processing unit 22, and the event operation received from the event output unit 18; The output image received from the image output unit 16 and the character information are combined, and an output instruction is transmitted to the output unit 60.

  The display unit 62, the sound reproduction unit 64, the vibration unit 66, and the illumination unit 68 execute each operation of display, sound reproduction, vibration, and lighting blinking based on each control signal input to the output unit 60. . As described above, the playback apparatus 1 plays back content by repeating output of the content and event action in accordance with an operation input by the user.

  Next, the hardware of the playback apparatus 1 will be described with reference to FIG. FIG. 2 is a schematic diagram showing the outer shape of the playback apparatus 1 and the configuration of each part of the present embodiment. In FIG. 2, the playback device 1 includes an external memory 32 in which content data is recorded, an operation input unit 50 configured with a keypad for inputting an operation for content playback, a display unit 62 configured with a display for display, An audio playback unit 64 configured with a speaker for outputting audio, an illumination unit 68 configured with a light emitting diode that gives a warning to the user when turned on, and a vibration configured with a vibrator motor (not shown) built in the playback device 1 A portion 66 is provided.

  Digital content is recorded in the external memory 32, and content data is input to the processing unit 10 of the playback apparatus 1 through the data input unit 40. The external memory 32 is attached to a slot having an external input interface of the playback device 1 and content data is taken out. By operating the operation input unit 50, the user browses and feels images and events reproduced from the display unit 62, the audio reproduction unit 64, the vibration unit 66, and the illumination unit 68.

  Next, the flow of reproduction processing performed by the reproduction apparatus 1 will be described with reference to FIG. FIG. 3 is a flowchart showing processing for outputting an event operation while displaying image data in the reproduction apparatus 1 according to the present embodiment. The above processing is realized by the CPU of the playback device 1 (not shown) reading and executing a program stored in the storage device and controlling each unit shown in FIG.

  Hereinafter, with reference to FIG. 3, a process of displaying digital content will be described. When the process is started, in S101, the data separation unit 12 initializes the currently displayed frame number to 1, and the process proceeds to S102. In S102, the data separation unit 12 acquires a frame image of frame number n, and the process proceeds to S103. The details of the frame information will be described later.

  In S103, the image output unit 16 acquires the image data from the content data, displays it on the image output unit 16, and proceeds to S104. In S104, the event determination unit 14 refers to the storage unit 30, and determines an event operation to be output from the event identification information based on the event correspondence information. The event output unit 18 outputs an event operation, and the process proceeds to S105.

  In S105, the operation processing unit 22 selects display data for content to be reproduced in accordance with a user operation input. If the user instruction returns to the previous frame, the process proceeds to S106, and if the user instruction proceeds to the next frame, the process proceeds to S108. In S106, the output processing unit 20 determines display data for the content to be reproduced. If the value of n is 1, that is, the display data to be output is the first “frame”, the process proceeds to S105 in order to wait for a user instruction. If the value of n is other than 1, the process proceeds to S107.

  In S107, the output processing unit 20 decreases the value of n by 1, and the process proceeds to S102. In S108, if the value of n is N, that is, if the display data to be output is the last “frame”, the process ends. If n is other than N, the process proceeds to S109. In S109, the output processing unit 20 increases the value of n by 1, and the process returns to S102.

  Next, manga which is content data will be described with reference to FIGS. FIG. 4 is a diagram illustrating an example of one page of a manga which is digital content. A frame 401 that is the first “frame” and a frame 402 that is the second “frame” are shown.

  In the frame 401 in FIG. 4, the font is large and thick because the speaker is screaming. Since the frame 402 normally asks, the font has a normal size. The event identification information associated with the event action includes font size, thickness, font shape such as Gothic and Mincho, and italics.

  By assigning an event action to the event specifying information as described above, a scene can be more strongly impressed by the user. The size and thickness of the font often reflect the thoughts of the person in the dialogue, and the larger the size, the thicker, the clearer the font shape, the stronger the event action. Is preferred.

  FIG. 5 is a table showing a specific example of “frame information” that is event specifying information of the frames 401 and 402. In the table of FIG. 5, the order of frames displayed when displaying the content is used as the frame number. The “size” of the “frame image” indicates the vertical and horizontal sizes of the displayed “frame image”. “Frame image” data indicates an identifier of image data, specifically, a file name or the like. The “shape” of “balloon” indicates the shape of the frame line that changes according to the emotion of the speaker.

  FIG. 6 is a diagram illustrating an example of a “balloon” shape. “Font” of “Balloon” indicates the type of serif font, and there are many that correspond to the emotion of the serif as well as the shape. “Serif” of “Balloon” is character data indicating a serif. The serif is stored as a character string by being replaced with an ASCII code or the like.

  Next, event correspondence information recorded in the storage unit 30 in the playback apparatus 1 will be described with reference to FIGS. In FIG. 7 and FIG. 8, the shape information of “Balloon” and the event action to be output are recorded in association with each other.

  In FIG. 9, the expansion / contraction rate (display magnification) of the image data to be displayed and the event operation to be output are recorded in association with each other. In the table of FIG. 9, the left column shows how much the image data is enlarged or reduced as event specifying information, and the right column shows the corresponding event action in the left column. It is shown in correspondence with.

  When the expansion / contraction ratio is 100%, that is, when there is no reduction, there is no event, assuming that the emphasized output is not performed. When the expansion / contraction rate is 75%, it is determined that the image that was originally larger is displayed smaller, and an event operation of “light lighting 1” is output in order to output a more emphasized event operation. Furthermore, when the expansion / contraction rate is 25%, the image is displayed in a very small scale, so it is determined that the image is drawn very large in the original image data, and the most severe event is shown. “Lighting 4” is performed.

  Here, an example in which the event specifying information is set in advance according to the hardware configuration of the playback device 1 will be described. However, the event identification information may be switched according to the user's preference within the range of events that can be set in the playback device 1. . For example, in FIG. 7, the user may set an event of “sound effect 1” as “balloon type” “type 1”, or may set only “vibration 1”. Further, “sound effect 2” may be set or “vibration 2” may be set. The setting may be changed to a combination of “sound effect 1” and “vibration 2”.

  Further, “sound effect A” or “vibration A” that can be used in the playback apparatus 1 but is not registered in the default event association data may be used. Also, nothing may be set. The same applies to the following examples.

  Next, a method for actually outputting an event action in response to content reproduction will be described with reference to FIGS. FIG. 10 is a schematic diagram showing how the playback device 1 outputs an event operation. FIG. 11 is a schematic diagram illustrating how the playback apparatus 1 plays back content data.

  In the playback apparatus 1 described above, event correspondence information is held for each hardware configuration of the playback apparatus 1 and is recorded by associating the event specifying information with the event operation. For example, in “device 1” having voice reproduction and vibration functions, a balloon shape, sound effects, and a vibration operation are associated with each other.

  Specifically, the sound reproduction includes the volume, height, length, and type of sound effect. Specifically, the vibration operation is the intensity and length of vibration. In order to execute the event operation in accordance with this, the playback device 901 performs sound effects and a vibration operation as shown in FIG. In addition, in “device 2” which has no sound reproduction or vibration function but has a light lighting function, a balloon shape and a light lighting operation are associated with each other as shown in FIG.

  Specifically, the light lighting operation includes color, lighting time, blinking speed, and the like. In order to execute the event operation according to this, the light lighting operation is performed like the playback device 902. Although it is content data having the same event specifying information as an input, it is possible to output an event operation according to the device, and the content capacity can be reduced because event information is not included in the content in vain.

  For example, if “Type 1” is screaming, “Type 2” is normal conversation, and “Type 3” is thinking in the head, the associated event action is “Type 3” rather than “Type 3”. It is preferable that “2” is an event operation having a stronger intensity than “type 2”. For example, sound intensity is high, loud, or long, for example. In addition, as an example of the vibe function, the vibration is strong or long.

  Next, a specific example of outputting an event operation based on the size of a frame image, which is one of event specifying information, will be described with reference to FIG. FIG. 10 is a schematic diagram showing how an event operation is output in the playback apparatus. In a device with a small display screen as shown in FIG. 10, the frame image may be reduced and displayed depending on the size of the frame image.

  When the screen size is 200 horizontal by 150 vertical, in 1001, the frame 401 can be displayed as it is, but in 1002, the frame 402 is reduced to 80% and displayed, and in comics the scene is effective for the reader. The information on the frame size, which is an important element to convey to the user, is lost.

  FIG. 11 shows a specific example of the event association data corresponding to the expansion / contraction rate of the frame image. For example, when the expansion / contraction ratio is 100%, that is, when there is no reduction, the event operation is not output, and when it is less than 100% and 75% or more, the event operation of “light lighting 1” is performed, so that the event operation of lighting the light in 25% increments is performed. Associate.

  The associated event action is preferably an event action having a higher strength as the expansion / contraction rate is smaller. Specifically, the event operation of “light lighting 4” increases the brightness compared to “light lighting 1”. By doing so, it is possible to supplement the frame size information lost during display by event operation. In this example, the brightness of the light is given as an example of the event action. It may be.

  In the above example, the example of the expansion / contraction rate is given. However, in a device having a large display screen, when the screen size is enlarged according to the screen size, the event operation may be associated with the magnification rate. The associated event action is preferably an event action having a lower intensity as the enlargement ratio is larger.

  Further, color information of image data may be used as event specifying information. In a magazine or the like, there are cases where printing is performed using different color information such as multi-color printing, three-color printing, and monochrome for each page or frame. In order to convey the content details to the user, an event action may be associated with the color information. In this case, it is preferable that the event action associated with the event action has a higher intensity as the number of associated event actions is more multicolor.

  In the above description, one display data corresponds to one frame, and one line is included in one frame. However, the present invention is not limited to this. One display data may correspond to one line or balloon, and an event operation may be set for each line or balloon. If the event operation is determined based on the display data and the hardware configuration of the playback device, substantially the same effect as in the present embodiment can be obtained.

  Further, in the above description, the event specifying information is information for determining the strength of the display data for the sake of simplification, but the information included in the event specifying information is for determining the strength of the display data. It may be other than information. Specifically, the event specifying information may be information for expressing joy, anger, sadness, enjoyment, anxiety, fear, and other psychological situations and emotions in the display data, for example. Any information may be used as long as the event operation corresponding to the display data can be set.

  The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments. Is also included in the technical scope of the present invention.

  Finally, each block of the playback device 1, in particular, the data separation unit 12 of the processing unit 10 and the event determination unit 14 may be configured by hardware logic, or realized by software using a CPU as follows. May be.

  That is, the playback device 1 includes a CPU (central processing unit) that executes instructions of a control program that realizes each function, a ROM (read only memory) that stores the program, a RAM (random access memory) that expands the program, A storage device (recording medium) such as a memory for storing the program and various data is provided. An object of the present invention is to provide a recording medium on which a program code (execution format program, intermediate code program, source program) of a control program of the playback apparatus 1 that is software that realizes the above-described functions is recorded so as to be readable by a computer. This can also be achieved by supplying the playback apparatus 1 and reading and executing the program code recorded on the recording medium by the computer (or CPU or MPU).
