JP 2003-304479 A

  It is considered to play music during slide show playback. For example, when music data is associated with each image played in a slide show and played, the display time of one image in the slide show is generally much shorter than the performance time of one piece of music, and the first part of the song is displayed. Just playing it will switch to the next image and switch the music. For this reason, there is a problem that the dissatisfaction remains in appreciation of the music and the production effect does not increase.

  An object of the present invention is to provide an image display device capable of improving the effect of production even when music is switched in accordance with image display switching.

In order to solve the above problems, the image display device of the present invention is
Recording means for storing a plurality of image data captured and generated by an imaging device, and music data associated with the image data;
Display means for displaying a reproduced image by the plurality of image data;
Image reproduction means for reading the plurality of image data and sequentially displaying the reproduced images on the display means;
Voice playback means for playing back the music data;
Rust portion storage means for storing information on the rust portion of the song of the music data;
It is characterized by further comprising reproduction control means for sequentially reading out information on the climax part of the music data associated with reproduced images sequentially displayed by the image reproduction means and sequentially reproducing the music of the climax part.

  The effect of the slide show can be enhanced.

  FIG. 1 is a block diagram showing a configuration of an image display apparatus according to an embodiment of the present invention. In FIG. 1, the image display device 1 is provided with a display device 11, a speaker 12, a CD player 13, and an input unit 14 (keyboard, mouse) as input / output devices. These are provided separately from the main body portion of the image display apparatus 1 and are connected to the main body portion via a cable to exchange signals. Of these, some input / output devices or all of the main body portion It is good also as a structure provided integrally.

  The image display device 1 is provided with a hard disk 22 as a storage device. The hard disk 22 can store sound (music) data input from the CD player 13 or the like and image data input from the electronic camera 30.

  The display device 11 is connected to the image signal processing unit 15 via the image signal output unit 16. The display device 11 displays an image based on the image signal processed by the image signal processing unit 15 and output via the image signal output unit 16 on the display screen. The speaker 12 is connected to the audio signal processing unit 17 via the audio signal output unit 18, and the audio based on the audio signal processed by the audio signal processing unit 17 and output via the audio signal output unit 18 is output. Output. The CD player 13 is connected to the audio signal processing unit 17 via the audio signal input unit 19. Other audio equipment can also be connected to the audio signal input unit 19, and audio data from the connected equipment is input. The CD player can reproduce audio information (music data) recorded on an inserted CD (compact disc). The reproduced data may be input to the audio signal processing unit 17 via the audio signal input unit 19, processed by the audio signal processing unit 17, and stored in the hard disk 22, and may be stored via the audio signal output unit 18. In some cases, an audio signal is output and audio is output from the speaker 12.

  The input unit 14 includes a keyboard, a mouse, and the like, and is connected to the CPU 21 via the USB interface unit 20. Various settings and operations related to operations can be performed via the CPU 21. The electronic camera 30 can also be connected via the USB interface unit 20. Then, the image data photographed by the electronic camera 30 can be transferred to the image display device 1 and stored in the hard disk 22 via the CPU 21.

  The CPU 21 controls operations of the image signal processing unit 15, the audio signal processing unit 17, and the hard disk 22. The ROM 23 is a read-only memory in which a control program for operating the CPU 21 is stored. The CPU 21 operates by reading a control program from the ROM 22 and executing it. The RAM 24 is a rewritable memory for temporarily storing image data, audio data, and other data.

  As described above, a photographic image taken by the electronic camera 30 can be taken into the image display device 1. The electronic camera 30 and the image display device 1 can be connected via a USB cable 31, and image data stored in the electronic camera 30 can be transferred to the image display device 1 via the USB cable 31. . In the image display device 1, image data is input to the CPU 21 via the USB interface unit 20, and the CPU 21 stores the image data in the hard disk 22. The image data from the electronic camera 30 may be stored in the hard disk 22 in the transferred format. However, if necessary, the image data is sent to the image signal processing unit 15 and processed after the image data is processed. You may save it.

  The electronic camera 30 can also record audio signals. These audio signals are recorded in association with moving images or still images. In general, audio data is included in image (moving image, still image) data and recorded. Image data containing such audio data (or associated with the audio data) (hereinafter referred to as audio image data) is also transferred to the image display device 1 and stored in the hard disk 22 in the same manner as described above. Can do.

  Music data reproduced from the CD by the CD player 13 is input to the audio signal processing unit 17 via the audio signal input unit 19. The audio signal processing unit 17 performs a process such as compression on the music data and stores the processed music data in the hard disk 22.

  Note that the audio signal processing unit 17 can also convert the input audio data into an analog audio signal and output the analog audio signal to the speaker 12 via the audio signal output unit 18 to output the audio. The audio data input to the audio signal processing unit 17 includes music data output from the CD player 13, music data stored on the hard disk 22, or audio data included in the image data.

  The image data stored in the hard disk 22 can be displayed on the display device 11. The image data read from the hard disk 22 is converted into an image signal suitable for display on the display device 11 by the image signal processing unit 15 and output to the display device 11 via the image signal output unit 16. Then, the display device 11 displays an image based on the input image signal on the display screen. When the next image data is read from the hard disk 22 and output to the image signal processing unit 15, the image displayed on the display device 11 is switched to an image based on the next image data. As described above, when the image data stored in the hard disk 22 is sequentially read and output to the image signal processing unit 15, a slide show reproduction in which the display images on the display device 11 are sequentially switched can be performed.

  A database file for managing stored image data is created on the hard disk 22. When the image data is newly saved, information is added to the database file.

  FIG. 2 is a diagram showing the contents of the image management database file created in this way. In FIG. 2, the database items include an image file name, shooting date / time, group name, order, and related music data name for one image data.

  When the image data is transferred from the electronic camera 30 and stored in the hard disk 22, the image data information is added to the image management database file in FIG. At this time, information written in the image management database file is an image file name and a shooting date and time. The image file name is a file name when the image data is stored in the hard disk 22, and the file name when the image data is stored by the electronic camera 30 is used as it is. The shooting date and time is the date and time when the image was shot and saved by the electronic camera 30, and this information is written in the image file. Therefore, the image file name and the shooting date and time are specified when the image data is transferred from the electronic camera 30, and can be written in the image management database file.

  “Group name” in the item of the image management database indicates a group of image data to be reproduced when performing slide show reproduction. Image data for which the same group name is set is sequentially displayed on the display device 11 during slide show reproduction of the group. This group name is set by the operator. This setting operation is started when the setting program stored in the ROM 23 is called and executed by the CPU 21 when a setting operation request is made by the operator from the input unit 14. The CPU 21 reads the image management database file from the hard disk 22 according to the setting program, and outputs the content to the image signal processing unit 15 as display format data that can be displayed on the display device 11. The image signal processing unit 15 converts the data input from the CPU 21 into an image signal that can be displayed on the display device 11, and outputs the image signal to the display device 11 via the image signal output unit 16. Then, a setting screen is displayed on the display screen of the display device 11. The operator can set a group name by selecting the image data to be included in the group by operating the input unit 14 while viewing the setting screen.

  The “order” of the item in the image management database indicates the order in which images in a group are sequentially displayed when a certain group is played back as a slide show. That is, processing for displaying the images in order from the first image is performed. This order is also set from the setting screen, but the setting operation may be omitted and the order may be automatically set in order of shooting date and time or in order of file name. In this embodiment, the order is automatically set in order of shooting date and time and written in the image management database.

  “Related music data name” in the item of the image management database indicates the name of music data to be reproduced when the image is displayed. The related music data name can be selected and set from music data stored in the hard disk 22 on the setting screen. The setting of the association between the image data and the music data can be set to either one music data for each image data or one music data for each group. When one music data is associated with a group when the slide show is reproduced, the associated music data is continuously reproduced until the slide show is finished. When different music data is associated with each image, the music data to be reproduced is switched every time the display of the image is switched. In the image management database, as shown in FIG. 2, the related music data name is written for each image. However, when one music data is set for the group, the related music data of the image belonging to the group is stored. In the name section, the same related music data name is written.

  Hereinafter, an operation during slide show reproduction will be described. The slide show reproduction is performed by the CPU 21 reading and executing the slide show reproduction program stored in the ROM 23. When the slide show reproduction program is executed, the CPU 21 displays a group selection screen for slide show reproduction on the display 11 via the image signal processing unit 15 and the image signal output unit 16. The operator selects a group to be reproduced by operating the input unit 14 while viewing this screen. Now, the operation when group 1 is selected will be described.

  FIG. 3 is a flowchart showing an operation during slide show reproduction. This flowchart shows an operation when a group in which one piece of music data is associated with a group is selected as a slide show reproduction target. First, when a group is selected (step S301), the image management database file shown in FIG. 2 is opened, and information on each image in the selected group is read (step S302). As described above, since the group 1 is selected here, the information of the image whose group name is “1” is read from the image management database file of FIG. The target images are image 01 to image 06. The related music data name of each image of group 1 is read from the image management database file of FIG. Here, since all the related music data names of the images 01 to 06 of the group 1 are “AA”, it can be seen that one music data is associated with the group. Therefore, it is understood that the music data AA may be continuously played until the slide show playback is completed. Next, the display time of each image is determined for six images (image 01 to image 06) to be displayed in the slide show reproduction (step S303). The determination of the display time will be described in detail below.

  In the present embodiment, when displaying images in a slide show, the display time of each image can be set to be constant, but the setting for automatically controlling the display time is also possible. When such automatic display time control is set, the display time is controlled as follows.

  First, images are sequentially displayed in order of shooting date and time (in order of shooting date and time). The shooting date and time is written in the image management database. The item “rank” in the image management database indicates the display order of images. In the case of group 1, the rank is in the order of shooting date and time. When the display time of each image is set to be constant, the images are displayed in the order set in “Order”. However, when the display time of each image is set to be automatically controlled, the setting of “Order” is used. Instead, they are displayed in order of shooting date. The display time of each image is determined based on the shooting date and time. The longer the shooting time interval between the currently displayed image and the next displayed image, the longer the display time of the currently displayed image.

  FIG. 4 is a diagram for explaining a method of determining the display time of each image when displaying the images of group 1 in FIG. Since the six images of group 01, image 01 to image 06, are taken in the order of photographing date and time, they are displayed in this order. The interval of the shooting date and time of each image with the next image is as shown in “Shooting Date and Time Interval with Next Image” in FIG. Since the image 06 is the image to be displayed last, there is no next image. Then, the display time of each image is determined based on the shooting date interval. First, the display time of the image 01 displayed first and the image 06 displayed last is a preset time. Here, the time is 6 seconds. It is assumed that the longest display time and the shortest display time can also be set. If the shooting date interval is too long, such as several years, the display time will be too long. If the shooting date interval is very short due to continuous shooting, the display time will be too short. Because there is. Here, the longest display time is 12 seconds which is twice 6 seconds, and the shortest display time is 3 seconds which is 1/2 of 6 seconds.

The display time of the image 01 is 6 seconds as set, but the shooting date interval with the image 02 is 306 seconds. The next image 02 has an imaging date interval with the image 03 of 433 seconds, which is about 1.4 times the 306 seconds of the image 01, so the display time is also increased according to the magnification. The display time of the image 02 is 6.0 * 433/306 = 8.49 ...
(* Is a multiplication symbol, / is a division symbol, and so on.)
As a result of the calculation, the value is 8.5 seconds.

Since the next image 03 has a shooting date and time interval of 65 seconds with respect to the image 04, 6.0 * 65/306 = 1.27...
Therefore, it is 1.3 seconds, but the display time of the image 03 is 3 seconds because it is shorter than the set minimum display time of 3 seconds. Since the photographing date and time interval between the image 04 and the image 05 is 2293 seconds, 6.0 * 2293/306 = 44.96...
Therefore, it is 45.0 seconds, but the display time of the image 04 is 12 seconds because it is longer than the set maximum display time of 12 seconds. Since the image 05 has a shooting date interval of 219 seconds with respect to the image 06, 6.0 * 219/306 = 4.29...
Therefore, it becomes 4.3 seconds. As described above, the display time of each image is determined.

  Returning to the description of the flowchart of FIG. 3, when the display time of each image is determined in step S303, the related music data name of each image of group 1 is read from the image management database file of FIG. As confirmed in step 302, since all the related music data names are “AA” for the images 01 to 06 of group 1, here, the music data AA only needs to be played until the slide show playback ends. Data reproduction is started (step S304). That is, music data with the music data name “AA” is read from the hard disk 22, input to the audio signal processing unit 17, processed, and output from the speaker 12 via the audio signal output unit 18. Next, the image name of the image to be displayed first (the image with the earliest shooting date / time) among the images of group 1 is read from the image management database file in FIG. 2 (step S305). Here, it is image 01. The image data of the image 01 is read out and displayed on the display device 11 (step S306). That is, the image data of the image 01 is read from the hard disk 22, input to the image signal processing unit 15, processed, the image signal is output via the image signal output unit 16, and the image is displayed on the display device 11. The While the image is displayed, it waits until the display time of the image set as shown in FIG. 4 elapses (step S307). This is done by measuring the passage of time with a timer built in the CPU 21. In the case of the image 01, when 6 seconds elapse, it is checked from the image management database file of FIG. 2 whether there is image data to be displayed next (step S308). If there is image data to be displayed next, the image data is read out (step S309), the processes of steps S306 and S307 are performed again, and the display of the next image data is performed for the time set as shown in FIG. Repeat the process to be performed. Here, since there is the image 02 as the image data to be displayed next, the image data of the image 02 is read out and displayed for 8.5 seconds. If there is no image data to be displayed next, the reproduction of the music data started in step S304 is terminated (step S310), the image display on the display device 11 is terminated (step S311), and the slide show reproduction of this group is performed. Terminate. In the case of the group 1, when the display of the image 06 to be displayed last is finished, the slide show reproduction is finished.

  In the present embodiment, when music data is reproduced, only the chorus portion of the song can be reproduced. As described above, associating image data with music data can associate one music data with one image data. In this case, during the slide show reproduction, the music data to be reproduced is switched every time the image display is switched. In slide show reproduction, the display time of one image can be set, but is usually set to several seconds. On the other hand, the music data is often for one song, and only the first part of the song can be reproduced during image display. Therefore, the effect of music reproduction can be improved by sequentially reproducing the chorus part which is a characteristic part of the music.

  In the present embodiment, in order to reproduce the chorus part of the song, the chorus part can be extracted and stored in advance. Extraction of the chorus part of the music is performed by the CPU 21 reading and executing the chorus part extraction program stored in the ROM 23. When the chorus part extraction program is activated, music data from which no chorus part has been extracted is read out of the music data stored in the hard disk 22, and the chorus part extraction process is sequentially performed. The chorus part extraction program is described in Japanese Patent Application Laid-Open No. 2004-233965 and will not be described in detail here.

  Such a chorus part extraction program extracts where the chorus part of a song is. The section of the chorus part is indicated by how many seconds from the beginning of the song to what number of seconds. Information on the section of the rust portion is stored, and there are the following two methods for storing the information.

  In the first method, information indicating where the chorus section is from where to where is stored in association with the original music data. FIG. 5A is a diagram showing the contents of a data file that stores music data and information indicating the section of the chorus portion of the music data. Corresponding to the music data name, the start position and end position of the chorus part (from the second to the second) are written. This data file is stored in the hard disk 22, and after the rust portion is extracted by the rust portion extraction program, information on the rust portion is added to the data file.

  In the second method, only the music data of the chorus section is extracted from the original music data and stored as chorus music data. That is, new music data for only the chorus part is created and stored in the hard disk 22. At this time, the relationship with the original music data is made known. FIG. 5B is a diagram showing the contents of a data file indicating the correspondence between the original music data and the music data of the chorus part. In this data file, information indicating the relationship between each music data name (file name) and the music data name (file name) of the chorus part of the music data is written. This data file is stored in the hard disk 22, the rust portion is extracted by the rust portion extraction program, the music data of the rust portion is created and stored, and then the original music data, the music data of the rust portion, Correspondence information of will be added.

  In the present embodiment, as described above, the rust portion of each music data is automatically extracted and stored using the rust portion extraction program. However, an operator listens to each music data in advance to check the rust portion. The section may be determined by searching for the portion, and may be written in the data file shown in FIG. Similarly, the operator searches for the rust portion and determines the section, cuts the section determined as the rust portion of the music data using a music data editing program, saves it with a file name, You may write in the data file of FIG.5 (b). Thus, various methods can be considered for determining the rust portion.

  Next, a slide show playback operation using playback of the chorus part of a song will be described. FIG. 6 is a flowchart showing an operation during slide show reproduction. This flowchart shows an operation when a group in which one piece of music data is associated with each image of the group is selected as a slide show reproduction target. First, when a group is selected (step S601), the image management database file shown in FIG. 2 is opened, and information on each selected image is read (step S602). Here, it is assumed that group 4 is selected. The information of the image whose group name is “4” is read from the image management database file of FIG. The target images are images 14, 15, and 16 of group 4. And the related music data name of each image of the group 4 is read. Since the related image data names of the images 14, 15, and 16 are DD, EE, and FF, respectively, it can be seen that different image data is associated with each image. Therefore, in the slide show reproduction, the music data to be reproduced must be switched every time the image display is switched. In the case of performing such music reproduction, in this embodiment, the chorus part as described above is reproduced. Next, the display time of each image is determined (step S603). This process may be the same as step S303 in FIG. 3, but here, unlike the case of FIG. 3, assuming that the display time of each image is set to be constant, the display time is A fixed time is determined for all images.

  Next, the image name of the image to be displayed first (image with the rank of 1) among the images in the group 4 is read out from the image database file in FIG. 2 (step S605). Here, it is the image 14. The image data of the image 14 is read out and displayed on the display device 11 (step S606). Next, the data name of the music data associated with the displayed image is read (step S607). This can be read from the image management database file of FIG. It can be seen from the image management database file in FIG. 2 that the image 14 currently displayed is associated with the music data DD. Then, by reading the data file of FIG. 5, the information of the climax part of the music data DD is read (step S608). When the data file of FIG. 5A is created, it can be seen that the chorus portion of the music data DD is from the position of 88 seconds to the position of 111 seconds from the beginning of the song. When the data file of FIG. 5B is created, it can be seen that the music data corresponding to the chorus portion of the music data DD is music data DDs. Based on such information, the climax part of the music data is reproduced (step S609). When the data file shown in FIG. 5A has been created, the music data DD stored in the hard disk 22 is read and started to be reproduced, but fast-forwarded and reproduced from the start position of the chorus part. When the data file shown in FIG. 5B has been created, the music data DDs, which is the music data of the chorus part stored in the hard disk 22, is read and reproduced.

  In this way, while displaying an image and playing the climax part of the music data associated with the image, it waits for the preset display time of the image to elapse (step S610). When the display time has elapsed, the reproduction of the music data of the rust portion is stopped (step S611), and it is checked whether there is image data to be displayed next (step S612). Here, since there is the image 15 as the image data to be displayed next, the image data of the image 15 is read (step S613), the process returns to step S606, and the processing up to step S611 is repeated. If there is no image data to be displayed next, the image display on the display device 11 is terminated (step S614), and the slide show reproduction of this group is terminated. In the case of the group 4, when the display of the image 16 to be displayed last is finished, the slide show reproduction is finished.

  Some image data recorded on the hard disk 22 includes audio information in addition to image information. In the following, an embodiment capable of dealing with a case where image data containing audio information exists will be described.

  When reproducing the image data containing the audio information, the audio data can be reproduced while displaying the image as follows. When the image data is read from the hard disk 22 and converted into an image signal for display on the display device 11 by the image signal processing unit 15, the audio data part is sent to the audio signal processing unit 17. Then, the audio signal processing unit 17 converts the audio signal into an audio signal for audio output from the speaker 12. In this way, in the case of image data with sound, an image can be displayed on the display device 11 and sound can be output from the speaker 12.

  As described with reference to the flowchart of FIG. 3, in the present embodiment, one piece of music data can be associated with a group composed of a plurality of image data. At this time, an operation mode is set in advance when image data with sound is included in the plurality of image data. There are basically two operation modes: audio data of audio-containing image data is reproduced or not. In the operation mode in which the audio data is not reproduced, even if the image data with audio is read and displayed, the audio signal processing unit 15 ignores the audio data of the image data with audio and reproduces it until then. Continue playing music data. In the mode for reproducing audio data, when the image data with audio is read and displayed, the audio signal processing unit 15 stops the reproduction of the music data and reproduces the audio data of the input image data with audio. To do. Then, when switching to the next image data (not audio data), the reproduction of the audio data is stopped and the music data is reproduced again.

  FIG. 7 is an operation flowchart for supporting reproduction of audio-containing image data in slide show reproduction. This flowchart shows an operation when a group in which one piece of music data is associated with a group is selected as a slide show playback target. First, when a group is selected (step S701), the image management database file shown in FIG. 2 is opened, and information on each image of the selected group is read (step S702). Here, it is assumed that group 3 is selected. The information of the image whose group name is “3” is read from the image management database file of FIG. The target images are images 08, 11, and 12. The related music data name of each image of group 3 is read from the image management database file of FIG. Here, since all the related music data names of the images 08, 11, and 12 of the group 3 are “CC”, it can be seen that one music data is associated with the group. Next, the display time of each image is determined (step S703). This process may be the same as step S303 in FIG. 3, but here, unlike the case of FIG. 3, assuming that the display time of each image is set to be constant, the display time is A fixed time is determined for all images. The related music data name of each image of group 3 is read from the image management database file of FIG. As confirmed in step S702, since the related music data names are all “CC” for the images in group 3, reproduction of the music data CC is started (step S704).

  Next, the image name of the image to be displayed first (image with the rank of 1) among the images in group 3 is read out from the image database file in FIG. 2 (step S705). Here, it is the image 08. The image data of the image 08 is read out and displayed on the display device 11 (step S706). Next, when image display processing is performed by the image signal processing unit 15, it is determined whether or not the image data contains audio data (step S707). If audio data is included, the setting of the operation mode described above is confirmed, and it is determined whether or not it is a mode for reproducing audio data (step S708). If the mode is for reproducing audio data, the audio data is sent from the image signal processing unit 15 to the audio signal processing unit 17, and the audio signal processing unit 17 interrupts the reproduction of the music data currently being reproduced (step). S709), reproduction of the audio data contained in the image data is started (step S710). Then, it waits for the preset display time of the image to elapse (step S711). If it is determined in step S707 that no audio data is included in the image data, or if it is determined in step S708 that the audio data is not in a playback mode, the process proceeds to step S711 and the image display time has elapsed. Wait to do.

  When the display time has elapsed, it is checked from the image management database in FIG. 2 whether there is an image to be displayed next (step S712). If there is next image data, it is confirmed whether or not the audio data currently contained in the image data is being reproduced (step S713). If the audio data is being reproduced, the reproduction is stopped (step S714), and the reproduction of the music data CC is resumed (step S715). The music data reproduction can be resumed by storing the interrupted position when the reproduction is interrupted in step S709 and restarting the reproduction from that position. Then, the next image data is read (step S716), the process returns to step S706 to display an image, and the processing up to step S715 is repeated. If it is determined in step S713 that the audio data is not being reproduced, the reproduction of the music data is continued. Therefore, the process proceeds to step S716 without doing anything, and the next image data is displayed. If there is no next image data in step S712, the sound output processing in the sound signal processing unit 17 is ended (step S717), and the image signal output processing in the image signal processing unit 15 is also ended (step S718). ), And slide show playback ends.

  In the processing in the flowchart of FIG. 7 as described above, when audio data is included in the image data, the operation in the mode of reproducing the audio data is interrupted and the reproduction of the music data is interrupted. The audio data contained in the image data is reproduced. However, the following operation may be performed as the operation in the mode of reproducing audio data. The operation mode is based on the premise that audio output can be performed in two-channel stereo. That is, there are two speakers 12, and there are also two systems of input / output of the audio signal processing unit 17 and the audio signal output unit 18. During playback of music data, playback is performed with stereo sound. When the audio-containing image data is read and the image is displayed, the output of one channel of the music data is stopped and output from only one channel. In this case, the audio signal of the music data is converted to monaural and output. Then, the audio data of the audio-containing image data is reproduced and output from one channel where the music data is not output. If the audio data is stereo, it is converted to monaural and output.

  When such an operation mode is set, in the flowchart of FIG. 7, in step S709, the reproduction of the music data is not interrupted but a process of outputting only from one channel is performed. In step S710, the audio data contained in the image data is reproduced from the other channel not used for reproducing the music data. In step S715, the music data playback is returned to stereo playback using two channels. The mode for reproducing the audio data included in the image data can be selected from the two modes described above, the selected mode is confirmed before step S709, and the subsequent operation is switched. You may comprise as follows.

  In the present embodiment, in the operation according to the flowchart of FIG. 6 (when reproducing the chorus portion of a song) and the operation according to the flowchart of FIG. 7 (when reproducing audio-containing image data), the image is displayed with a constant display time. However, as described in step S303 of the flowchart of FIG. 3, the display time of each image may be controlled by the shooting date and time interval with the next image to be displayed.
