  However, the above-mentioned proposed apparatus and system feels that the display time of the still screen is too long when the content is viewed without sound, or the motion of the screen when the moving image screen is displayed by skipping the still screen. Cannot solve problems such as unnaturalness and uncomfortable feeling.

  Therefore, an object of the present invention is to provide a computer-executable program related to display control that enables a moving image display without a sense of incongruity depending on the presence or absence of sound in providing content by moving image with sound.

In order to solve the above-described problems, the present invention provides a computer-executable program for causing a computer to execute display control relating to a moving image. In the computer, the current frame display information stored in the current frame storage area and the previous frame are stored. a discrepancy determination procedure for determining whether the difference between each other of the display information by comparing the display information of the previous frame stored in the storage area, a difference in the display information is determined to Ru chromatic by the mismatch determination procedure A display unit for displaying the display information of the current frame on the display unit, and displaying the current frame in the previous frame storage area after displaying the current frame, and storing the next frame in the current frame storage area. a step of performing said mismatch determination procedure, when the difference in the display information by said mismatch determination procedure is not If you cross, among the frames it is determined that there is no difference in the display information, the said display information of the current frame in the range number of frames from frame displayed by the mismatch frame display step does not exceed a first predetermined number This is achieved by causing a matching frame display procedure to be displayed on the display unit.

  A computer that installs and executes such a program automatically determines a screen (frame) that does not change, displays a screen that has changed, and also displays a screen that has not changed for a while. It is possible to realize display control without a sense of incongruity.

  As means for solving the above-described problems, the present invention may be a moving image display control apparatus realized by executing the above program, or a storage medium storing the above program.

  The invention of the present application makes it possible to automatically display a screen that does not change with one content and skip the display of the screen, thereby making it possible for the student to display without any sense of incongruity. In addition, by enabling such display control, it is possible to eliminate the need to create individual contents according to the presence or absence of sound.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a configuration of a content providing system according to an embodiment of the present invention. In FIG. 1, a content providing server 200 that provides content and a client 300 of a user who uses the content are connected via the network 11, and the content providing server 200 receives content in response to a request from the client 300. provide. Here, the content is, for example, content for learning, and includes content displayed by moving images and explanation by voice (narration).

  The client 300 is a computer controlled by a CPU (central processing unit), and each processing unit is configured by a program that can be executed by the computer, and is realized by executing the program. In addition, such a program necessary for the client 300 is installed by the installer 309 from the storage medium 310 stored in advance. Alternatively, the entire program may be downloaded from the content providing server 200 via the network 11 and installed.

  When such a program is installed, the content display control unit 320 is configured in the client 300. The content display control unit 320 includes a table of contents display unit 322 that displays a table of contents, an engine 330 that controls display of content according to the presence or absence of voice (narration), a video, audio, and scenario configured in units of chapters or sections. A scenario 340 to be shown, an animation file 351 for storing a moving image necessary according to an item selected by the user from the table of contents, and an audio file 352 for storing a sound corresponding to the moving image.

  The engine 330 further includes an audio mode input unit 331 that allows the user to select whether or not there is audio and a display frame determination unit 332 that determines and displays a frame to be displayed according to the presence or absence of audio. The frame is displayed using, for example, a Web browser.

  In addition, the client 300 includes a standard input unit such as a mouse and a keyboard, a display unit for displaying information, a communication unit for connecting to a network and the Internet, a memory unit for storing necessary information, and an auxiliary unit. A storage device, a drive unit for controlling the storage medium 310, and the like are included.

  The content providing server 200 manages content data to be displayed as information provided to the client 300 by the content sending unit 210 and the content sending unit 210 that send information related to the requested content in response to a request from the client 300. The table of contents data 221, the engine unit 222 executed by the client 300, the scenario file 223 for managing the scenario for each chapter, the animation file 224 for managing the moving image data required by the scenario 223, and the scenario 223 And an audio file 225 for managing audio data.

  The content providing server 200 reads out the table of contents data of the content requested by the client 300 from the table of contents data 221 by the content sending unit 210 and sends it out via the network 11, and the engine unit 222 controls the display of the content. From the network 11 and sent via the network 11.

  When the user selects a desired chapter from the table of contents displayed on the client 300, the content providing server 200 reads a scenario corresponding to the chapter from the scenario file 223 and sends it out via the network 11.

  Thereafter, in accordance with a request for moving image data and audio data according to the scenario 340 from the client 300, the content providing server 200 causes the content sending unit 210 to send the animation file 224 and the audio file 225 to the network 11 for each page. Forward through.

FIG. 2 is a diagram illustrating a configuration of content. 2, one content, Ru is composed of a plurality of chapters. Each chapter is composed of an HTML (HyperText Markup Language) file. HTML, Chapter 2. HTML, ..., n. It is configured like HTML and managed by table of contents data 221.

  The engine unit 222 (for example, an engine.swf file) is a processing unit for determining which chapter scenario should be read according to a variable given from the HTML file of each chapter.

  A scenario is configured for each chapter. For example, a scenario file 223 is configured as in Chapter 1 scenario, Chapter 2 scenario,. In each scenario file 223, pages are designated in the order to be executed, and animation files and audio files are designated by the page numbers. One page includes a plurality of frames for realizing a moving image.

  An engine and data file loading procedure of the content providing server 200 and the client 300 in such a content configuration will be described.

  FIG. 3 is a diagram for explaining the loading procedure of the engine and the data file. In FIG. 3, when the HTML of Chapter n is displayed (0), the client 300 reads the engine from the content providing server 200 and displays it on the browser (1). That is, an engine screen that can be operated by the user is displayed by the engine unit 330 configured in the client 300.

  Next, the n-th chapter scenario specified by the variable given from the n-th chapter HTML is read from the content providing server 200 and stored as a scenario 340 in the storage area (2). In accordance with the read chapter n scenario, the animation is loaded in units of pages specified in order, and stored in the storage area as an animation file 351 (3). Subsequently, an audio file corresponding to the animation is loaded (4).

  When the user designates the voice mode, the reproduction of animation and voice is started when all the voice files are loaded (5).

  Here, in the engine screen displayed on the client 300, in order to allow the user to operate animation, a next button for proceeding to the next page, a back button for returning to the previous page, and a current display It includes a slider that shows the playback state of the animation on the page being played.

  In the present embodiment, the moving image is formed by displaying a plurality of frames in units of frames at regular time intervals. Further, the moving image is changed by adding animation data to one frame. In the above description, the animation data transmitted from the content providing server 200 to the client 300 includes this animation data.

  Therefore, when audio is not required, display control is performed so that a frame without animation data is not displayed but a frame with animation data is displayed. Alternatively, display control may be performed so that the current frame is not displayed by determining the difference in display information between the previous frame and the current frame, instead of determining whether there is animation data.

  Furthermore, if the control does not simply display frames that do not change, the screen changes may feel unnatural, or if there is a screen that you want to display even if there is no change, it is forcibly displayed in advance when creating the content. By providing the flag, it is possible to finely control display for a frame that does not change.

  In addition, it is possible to display a frame with a predetermined number of frames before and after the display of a frame with a change so that the moving image display starts and ends naturally.

  A method for realizing such display control according to the present invention will be described in detail below.

  First, a data structure related to content display control according to the presence or absence of sound according to the present invention will be described.

  FIG. 4 is a diagram illustrating a data configuration related to content display control according to the presence or absence of sound. In FIG. 4, the audio flag area 1 stores the presence / absence of audio selected by the user. For example, “1” is set when voice is selected, and “2” is set when voice is not selected.

  The frame area 2 stores a plurality of frames downloaded for each page. In the frame area 2, a frame number for specifying a frame, a forced display flag indicating that the frame should be displayed even when the user selects no sound, and data regarding display of the frame And a display data part for storing In the display data portion, for example, text only data, a pointer to the audio file 352, a pointer to the animation file 351, and the like are set.

  The current frame 3a (indicated by frame_0 in the following flowchart) is an area for temporarily storing the frame just read.

  The previous frame 3b (indicated by frame_p in the following flowchart) is an area for temporarily storing the frame read immediately before.

  The frame accumulation buffer 4 is an area for accumulating the maximum predetermined number of frames (for example, indicated by L) up to a frame with a change.

  FIG. 5 is a diagram showing an example of a screen that allows the user to select whether or not there is sound. In FIG. 5, when the content is a learning material, for example, a screen 50 is displayed by the voice mode input unit 331. On the screen 50, for example, in response to a message “Do you want to learn while listening to the voice?”, The user selects (clicks) “Yes” or “No” using a mouse or the like. When “Yes” is clicked by the user, “1” is set in the voice flag area 1 by the voice mode input unit 331. On the other hand, when “No” is clicked by the user, the voice mode input unit 331 sets “0” in the voice flag area 1.

  The content display control process according to the present invention will be described with reference to FIGS.

  FIG. 6 is a flowchart for explaining the overall outline of the content display control process. In FIG. 6, the content display control unit 320 causes the audio mode input unit 331 to display the audio selection screen (screen 50 shown in FIG. 5) on the client 300 when starting the content (learning) (step S101). The user selects the presence / absence of sound with a mouse or the like (step S102). For example, when the user learns at work, if the user wants to learn by deleting the voice so as not to disturb the surrounding workers, the user selects “no voice”.

  When the sound mode is set, the table of contents display unit 322 displays the table of contents (step S103). Here, when the user designates termination, the content display control processing is terminated.

  On the other hand, when the user selects a desired chapter or section from the table of contents (step S104), the corresponding HTML file is displayed, and at the same time, the content display control unit 320 loads the engine by the engine unit 330 (step S105). . An engine screen that allows the user to operate the frame on the browser is displayed. Then, the engine unit 330 loads a scenario corresponding to the chapter or section selected by the user (step S106).

  Based on the scenario 340 stored in the client 300, the content display control unit 320 acquires an animation file for each page from the content providing server 200 and stores it in the animation file 351.

  The content display control unit 320 determines whether or not the page is finished (step S108). That is, it is determined whether there is a page to be acquired in step S107. If all pages have been completed, the process returns to step S103 to display the table of contents again.

  On the other hand, if all pages have not ended, the content display control unit 320 refers to the audio flag area 1 and determines whether or not the user has selected no audio (step S109). If there is no sound, the process proceeds to the display frame determination process (step S200).

  When the presence of sound is selected, the content display control unit 320 acquires the sound file corresponding to the page from the content providing server 200 and stores it in the sound file 352 (step S110).

  Then, the content display control unit 320 reproduces audio data from the audio file 352 (step S111), and reads animation data corresponding to the frames in order from the animation file 351 (step S112). The content display control unit 320 determines whether or not all frames have been completed (step S113). That is, it is determined whether or not a frame has been read in step S112. If no frame has been read, it is determined that the display of all the frames has been completed, and the process returns to step S107 to process the next page. On the other hand, when the frame is read, the frame is displayed and the process returns to step S112 to read the next frame.

  The processing from step S110 to S114 described above is executed when the content (learning material) is displayed as a moving image with sound (narration).

  The display frame determination process (step S200) in which the content (learning material) is displayed as a moving image in a natural flow without sound (narration) will be described in detail with reference to FIGS.

  FIG. 7 is a flowchart for explaining a process of displaying a predetermined number of frames before the display start of a frame having a change in the display frame determination process. FIG. 8 is a flowchart for explaining a process of displaying a frame with a change and a predetermined number of frames after the display of a frame with a change.

  In FIG. 7, the display frame determination unit 332 of the content display control unit 320 clears the buffer frame number b indicating the number of frames stored in the frame storage buffer 4 to zero (step S201). The number b of frames in the buffer indicates the number of frames accumulated in the frame accumulation buffer 4 before the start of frame change and corresponds to the storage position in the frame accumulation buffer 4.

  The display frame determination unit 332 reads the first frame in the page as frame_0 in the current frame 3a (step S203), and displays frame_0 on the client 300 (step S203). Thereafter, frame_0 is copied to frame_p (step S204).

  Then, the display frame determination unit 332 reads the next frame into frame_0 (step S205), and determines whether or not the frame has ended (step S206). That is, if the next frame cannot be read, it is determined that all frames have been completed, and the process proceeds to step S221.

  On the other hand, when the next frame can be read into frame_0, the display frame determination unit 332 refers to the forced display flag in the frame area 2 to determine whether the frame read into frame_0 is forcibly displayed. (Step S207). When the forced display is present, the display frame determination unit 332 clears the buffer frame number b to zero (step S208), and proceeds to step S223.

  Steps S207 and S208 can be omitted by setting the predetermined frame number L to a sufficient number.

  On the other hand, when there is no forced display, the display frame determination unit 332 determines whether or not the frame is changed by comparing the previous frame stored as frame_p in the previous frame 3b with frame_0. (Step S209). If the content data of the frames do not match, it is determined that the frame has changed. In the case of determination based on the presence / absence of an animation, it is determined whether or not the image is an animation by checking whether or not the pointer to the animation file 351 is set with reference to the display data portion of the frame region 2. The same applies to the process for determining whether or not the frame has the same change in the following cases when the determination is based on the presence or absence of an animation.

When a certain frame of change, or, if it is determined that the start of the animation, the display frame determination unit 332 displays a frame with change proceeds to step S222, or to start the animation.

  Hereinafter, the presence / absence of a change includes the presence / absence of an animation. It is assumed that a frame including an animation is included in a frame having a change, and a frame including no animation is included in a frame having no change. Further, in the case of displaying a frame with a change, it is assumed that the animation is started, and that the meaning of the end of the animation is included in the first frame without a change.

  On the other hand, when determining that the frame is unchanged, the display frame determining unit 332 increments the buffer frame number b by 1 (step S210), and the buffer frame number b is 1 less than the predetermined number L before the change. It is determined whether or not it is larger than “L−1” (step S211). If it is “L−1” or less, the display frame determination unit 332 proceeds to step S214.

  On the other hand, when the value is larger than “L−1”, the display frame determination unit 332 shifts the data of each frame stored in the frame accumulation buffer 4 one address before (step S212). Here, the data of the frame stored at the address corresponding to the number of frames in buffer b = 1 is erased. Also, in accordance with the shift in step S212, the value “L−1” is set to the number b of frames in the buffer.

  Then, the display frame determination unit 332 stores frame_p in the b-th position of the frame accumulation buffer 4 (step S214), copies frame_0 to frame_p (step S215), and returns to step S205 to read the next frame.

  Steps S205 to S215 are processing for storing in the frame accumulation buffer 4 in order to display a predetermined number of frames before a frame with a change by prefetching from the frame area 2.

  In step S206, when the display frame determination unit 332 determines that all the frames of the page have been completed, the display frame determination unit 332 determines whether or not the frame number b in the buffer is zero (step S221). If the buffer frame number b is zero, the process returns from the display frame determination process to step S107 in FIG. 6, and the next page is read.

  On the other hand, when determining that the number b of frames in the buffer is not zero, the display frame determination unit 332 continuously displays frames from the first to b-th (up to L-th) frames in the frame accumulation buffer 4 (step S222). . Then, the display frame determination unit 332 determines whether or not all frames have been completed, as in step S205 (step S223). If all frames have been completed, the process returns from the display frame determination process and proceeds to step S107 in FIG.

  On the other hand, when all the frames have not been completed, the display frame determination unit 332 displays frame_0 (step S224). The displayed frame_0 is a frame with a change or a frame with forced display.

  Then, the display frame determination unit 332 copies frame_0 to frame_p, and proceeds to step S301 in FIG.

  Steps S222 to S224 described above are processes for displaying the predetermined number of frames (the maximum L number of frames) before the changed frame and the changed frame.

  In step S301 of FIG. 8, the display frame determination unit 332 reads the next frame from the frame area 2 into frame_0 (step S301), and determines whether or not the frame has ended (step S302). That is, if the next frame cannot be read, the display frame determination unit 332 determines that all frames have been completed, returns from the display frame determination process, and proceeds to step S107 in FIG.

  On the other hand, when the next frame can be read into frame_0, the display frame determination unit 332 determines whether the frame is changed by comparing frame_p with frame_0 (step S303). If the frame is unchanged, the display frame determination unit 332 proceeds to step S311 in order to display a predetermined number of frames even after the display of the changed frame is completed.

  On the other hand, if it is determined that the frames with changes are continuous, the display frame determination unit 332 displays frame_0 (step S304), copies frame_0 to frame_p (step S305), and reads the next frame. The process returns to step S301.

  Steps S301 to S305 described above are processing for displaying a frame when there are consecutive frames with changes.

  On the other hand, if it is determined in step S303 that the changed frame has ended, the display frame determination unit 332 performs steps S311 to S318.

  The display frame determination unit 332 clears the frame number a to zero using the frame number a after the display of the changed frame is completed (step S311). The number of frames a indicates the number of frames that are continuously displayed after the display of the changed frames.

  The display frame determination unit 332 increments the frame number a by 1 (step S312), and determines whether the frame number a is greater than the predetermined frame number L (step S313). The predetermined frame number L may be the same as or different from the predetermined frame number before the display of the changed frame. If it is larger than the predetermined frame number L, the process returns to step S205 in FIG.

  On the other hand, when the frame number a is equal to or less than the predetermined frame number L, the display frame determination unit 332 displays frame_0 (step S314) and copies frame_0 to frame_p (step S315).

  Then, the display frame determination unit 332 reads the next frame into frame_0 (step S316), and determines whether or not the frame has ended (step S317). That is, if the next frame cannot be read, the display frame determination unit 332 determines that all frames have been completed, returns from the display frame determination process, and proceeds to step S107 in FIG.

  On the other hand, when the next frame can be read into frame_0, the display frame determination unit 332 determines whether the frame is changed by comparing frame_p with frame_0 (step S318). If the frame does not change, the display frame determination unit 332 returns to step S312 in order to display the predetermined number of frames after the display of the changed frame. On the other hand, if it is determined that the display of the frame with the change has been resumed, the display frame determination unit 332 returns to step S304 to perform the process of displaying the frame with the change.

  Steps S311 to S318 described above are processes for displaying a predetermined number of frames even if there is no change after the display of a changeable frame.

  In this way, natural display control can be achieved by displaying a predetermined number of frames even if there is no change before and after the display of a frame with a change, instead of displaying only the frame part with a change. can do. Further, if necessary, it is possible to control to display a preset frame to be displayed.

  Therefore, according to the present application, it is possible to automatically display a screen that does not change with one content and skip the display of the screen, thereby enabling a display that does not give the student a sense of discomfort. In addition, by enabling such display control, it is possible to eliminate the need to create individual contents according to the presence or absence of sound.

  Furthermore, even if the user selects no sound, the user can refer to the content without a sense of incongruity in the switching of the motion of the moving image. Also, it is possible to refer to the content in a shorter time than when there is audio. For example, this is particularly effective when the learning content is referred to at the workplace. Further, the present application may be applied when it is desired to refer to the content in a short time regardless of the presence or absence of sound.

  The table of contents data 221, the engine unit 222, the scenario file 223, the animation file 224, and the audio file 225 managed by the content providing server 200 are sent to the client 300 via the storage medium storing them in advance without going through the network 11.
