Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a video signal recording / reproducing apparatus, and more particularly to a video signal such as a television program and a video signal obtained by a user himself / herself photographed by a video recorder integrated with a camera or the like, mixed and recorded on the same recording medium. The present invention relates to a video signal recording / reproducing apparatus which displays recorded video information on a small screen (thumbnail) and selectively reproduces any recorded video information.
[0002]
[Prior art]
In recent years, hard disk recorders and DVD (Digital Versatile Disc) recorders have been released as video signal recording / reproducing apparatuses for recording and reproducing video signals on recording media. In particular, in these video signal recording / reproducing devices, a plurality of small images (thumbnails) representing a recorded video signal are displayed on a screen in order for a user to select a video signal to be reproduced. The user selects an arbitrary thumbnail from among them.
[0003]
At this time, the arrangement order of arranging a plurality of thumbnails on the screen may be in the order of recording date and time, or in genre. In this case, even in the recording date order, the thumbnails are simply arranged in order, and the thumbnails are not usually arranged on a calendar-like table in which the date and the day of the week are represented two-dimensionally. . This means that when it comes to television broadcasts or content acquired through a rapidly evolving broadband network, the time of acquisition isn't very significant to the user, Or, since a rough time, such as whether the video was recorded a long time ago, is only a clue to the search, a calendar-like display does not make much sense.
[0004]
On the other hand, in a still image taken by a digital camera taken by a user himself or a moving image taken by a camera recorder, the date and time of photography is important. In view of the above, a technique of arranging a list of captured images in a calendar form for a digital camera has been conventionally proposed (for example, see Patent Document 1). That is, Patent Document 1 discloses a configuration in which a reduced image (thumbnail) of a recorded captured image is displayed in a calendar for each period, and the captured image is reproduced / displayed by pointing to a desired image in the calendar. Have been.

[0006]
[Problems to be solved by the invention]
By the way, in a recording / reproducing apparatus which stores many video signals using a large-capacity recording medium and reproduces desired video information as appropriate, such as a hard disk recorder, not only a content such as a television broadcast program but also a content is recorded. Also, a video signal of a moving image photographed by a camera recorder and a still image signal photographed by a digital camera can be stored, and can be appropriately selected and reproduced.
[0007]
Here, in the case of a video signal to be recorded, especially in the case of a video signal of a moving image, whether it is a video signal received by a set-top box or the like and input from an external input terminal, or captured by a camera recorder and input from an external input terminal There is no particular distinction in the input terminal or signal form, such as whether it is a video signal of a received moving image or a video signal of a moving image received by the receiving means. Therefore, in a conventional video signal recording / reproducing apparatus such as a hard disk recorder, it is particularly necessary to determine whether a captured image recorded by a camera recorder or the like recorded through an external input terminal or a moving image of a television program obtained by a built-in receiving unit or a set-top box. They are recorded without distinction, and are displayed as thumbnails in the order of recording on the hard disk, regardless of the recorded contents, in the reproducing operation.
[0008]
For this reason, in a conventional video signal recording / reproducing apparatus, a moving image photographed by a camera recorder often has a significant date for a photographer (for example, birthday, travel, etc.). The user selects a thumbnail of a moving image photographed by the camera recorder displayed in a manner mixed with the thumbnail of the recorded content of the program, which makes it difficult to find a desired photographed image at a glance, and the selection operation is cumbersome.
[0009]
On the other hand, the conventional video signal recording / reproducing apparatus described in Patent Literature 1 supports only a calendar display, and a recorded video signal is used for a television program or the like in which the date has no significance to the user. There is a problem that even a video signal is displayed on a calendar, making it difficult for a user to understand.
[0010]
The present invention has been made in view of the above points, and in the case where a video signal such as a television program is recorded, and in the case where a user himself / herself is photographed with a camera recorder such as a camera-integrated video recorder, the video signal is recorded. In some cases, an object of the present invention is to provide a video signal recording / reproducing apparatus which makes a selection method at the time of reproduction appropriate.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, a video signal recording / reproducing apparatus according to the present invention includes a video signal recorded on a recording medium by a first recording operation, and a recording medium by a second recording operation different from the first recording operation. A video signal recording / reproducing apparatus for reproducing the video signal recorded above from a recording medium, wherein the video signal recorded by a first recording operation is recorded on a recording medium as a video signal of a first classification; Recording means for recording a video signal to be recorded by the recording operation 2 as a video signal of a second classification different from the first classification on a recording medium; reproducing means for reproducing a video signal recorded on the recording medium; In order to reproduce a desired video signal of the first classification from the video signals recorded on the recording medium, a representative image of each video signal of the first classification is displayed on an internal or external display. Listed on the device And a plurality of sections indicating a plurality of dates for reproducing a video signal having a desired date, which is the second classification, from among the video signals recorded on the recording medium. The second selected image display means for displaying the arranged images on the display device, one of a representative image list display by the first selected image display means and a display of a plurality of sections by the second selected image display means. When the user selects and further displays the list, instructs to select an arbitrary representative image from among the plurality of representative images, and when the display of a plurality of sections is selected, selects a section of an arbitrary date among the plurality of sections. Selection instructing means for instructing, and reproducing means for reproducing, from a recording medium, a video signal corresponding to the representative image selected and instructed by the selection instructing means, or a video signal corresponding to a date of an arbitrary section selected and instructed. Control system It is obtained by a structure having a unit.
[0012]
According to the present invention, at the time of recording, video signals of the first classification or the second classification are recorded in distinction according to a recording operation, and at the time of selective reproduction of the video signals of the first classification, a representative image of each video signal is selectively reproduced. Is displayed in a list on a display device connected internally or externally, and an arbitrary representative image is selected and instructed. At the time of selective reproduction of the video signal of the second classification, a plurality of sections indicating a plurality of dates are displayed. By displaying the arranged image on the display device and instructing to select a section of an arbitrary date from the plurality of sections, it is possible to easily select and reproduce from a plurality of recorded video signals.
[0013]
Here, the recording means may be a means for recording a still image signal and a moving image signal as the video signal of the second classification, and the second selected image display means may be a two-dimensional image signal. Is set to identify a still image signal and a moving image signal in a section of a date corresponding to a video signal which is a second classification recorded on a recording medium among a plurality of sections indicating each date arranged in the recording medium. It may be means for displaying an icon in a given shape. Further, at the time of selective reproduction of the video signal which is the first classification, a title may be displayed instead of the representative image.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an embodiment of a video signal recording / reproducing apparatus according to the present invention, and FIG. 2 is a schematic system diagram of an example of a video signal recording / reproducing system centering on the video signal recording / reproducing apparatus of the present invention.
[0015]
As shown in FIG. 2, a recording / reproducing apparatus 1 according to an embodiment of the present invention has an external input terminal 2, a card slot 3, an infrared light receiving unit 4, an antenna input terminal 5, and an output terminal 6, and An image signal of a television broadcast is received by an antenna 18 connected to the input terminal 5. Here, in addition to the broadcast reception, an input from a communication line may be provided so that a video signal can be obtained from a broadband Internet service that has been spreading in recent years.
[0016]
When a video signal supplied from another recording / reproducing device such as a set-top box or a camera-integrated recorder is input to the external input terminal 2, this signal can be recorded. The output terminal 6 is connected to a display 19, and the display 19 displays a received image, a reproduced image, an operation screen, and the like.
[0017]
The card slot 3 is for inserting a card containing semiconductor media such as an SD card or a memory stick, and a card on which a still image taken by a digital camera is recorded is inserted into the card slot 3 to record the image. This still image can be captured and recorded on a recording medium (for example, a hard disk) in the playback device 1. Further, the infrared light receiving section 4 receives infrared light from which a signal corresponding to a user operation is transmitted from a remote controller (hereinafter abbreviated as a remote controller) 20.
[0018]
Next, the internal configuration of the recording / reproducing apparatus 1 will be described with reference to the block diagram of FIG. 1. A television broadcast signal received by an antenna (18 in FIG. 2) is received by a receiving unit 7 via an antenna input terminal 5. The switching unit 8 switches between a video signal obtained by channel selection and signal processing and a video signal supplied from another recording / reproducing device such as a set-top box or a camera-integrated recorder via the external input terminal 2. , Any one of the video signals is arbitrarily selected and supplied to the recording signal processing unit 9.
[0019]
The video signal that has been subjected to recording signal processing such as high-efficiency coding such as MPEG (Moving Picture Experts Group) or error correction code in the recording signal processing unit 9 as appropriate is added with additional information such as date information as necessary. After being adjusted to a signal form suitable for recording, it is recorded on a hard disk in a hard disk drive (HDD) 10. In addition, still image information and the like recorded on the memory card inserted through the card slot 3 are also supplied to the recording signal processing unit 9 via the bus 17 and are arranged in a form suitable for recording on the hard disk. Recorded on the hard disk.
[0020]
When recording or erasing a video signal, the microprocessor 11 revises TOC (Table Of Contents) information recorded on the hard disk in the HDD 10 as information representing recorded content.
[0021]
Although the control line is omitted in FIG. 1, switching of the channel of the receiving means 7 for receiving a signal from the antenna input terminal 5 and switching between the antenna input and the external input of the switching unit 8 will be described later. The microprocessor 11 controls the receiving means 7 and the switching unit 8 in response to a user's remote control operation in a method.
[0022]
The video signal recorded on the hard disk in the HDD 10 is supplied to a reproduction signal processing unit 15 where the reproduction signal processing such as error correction and decoding of encoding such as MPEG is performed. After that, it is output from the output terminal 6. When the recording / reproducing apparatus 1 is turned on but not recording or reproducing, the video signal of the television broadcast received by the receiving means 7 or the video signal coming from the external input terminal 2 is output. .
[0023]
Here, guide information to the user when performing various operations (in the simplest case, when a channel is switched, a channel number of a newly received channel is displayed superimposed on a received image) and the like. Information stored in a RAM (random access memory) 12 or a ROM (read only memory) 13 by the microprocessor 11 as appropriate for displaying a reproduction information selection screen (navigation screen) at the time of reproduction described later. Is converted into a signal form suitable for display on a display by the video signal conversion unit 14 including the character generator function, and then the switching / superposition unit 16 outputs the video information from the reproduction signal processing unit 15. The video signal is output after being switched with the reproduced video signal or superimposed on the reproduced video signal.
[0024]
The user's operation is performed by the remote control 20, and after the remote control signal transmitted from the remote control 20 is received by the infrared light receiving unit 4, the signal is sent to the microprocessor 11 through the bus 17. The microprocessor 11 controls each unit of the recording / reproducing apparatus 1 according to the received remote control signal. The processing program and the processing data of the microprocessor 11 are stored in the ROM 13, and the setting information by the user and the information being processed are stored in the RAM 12. Here, information that needs to be stored until the next use is stored in the non-volatile RAM, and information that needs to be temporarily stored may be stored in the DRAM.
[0025]
It should be noted that the bus 17 connected to the microprocessor 11 describes only the main components in data exchange, and the entire recording and reproducing apparatus including the above-mentioned receiving means 7 and the like, in which the bus is not shown in FIG. Is controlled by the microprocessor 11.
[0026]
FIG. 3 shows an external view of an example of the remote controller 20. Generally, a remote controller is provided with many buttons so that various operations can be performed. FIG. 3 shows only some of the buttons related to the present invention. In FIG. 3, various buttons 21 marked PLAY, REW, FF, REC, STOP, and PAUSE slightly below the center represent buttons for playback, rewind, fast forward, record, stop, and pause, respectively. Generally, this is an operation button often used in a video tape recorder or the like. Here, as is often done, with the operation of only the recording button, the recording operation starts even when the recording button is pressed by mistake, so that the recording operation is performed only when the REC button and the PLAY button are simultaneously pressed. ing.
[0027]
A button 22 consisting of a pair of + and-buttons is a channel button. As shown in FIG. 4, each time the + button is pressed, the channel selectively received by the receiving means 7 is sequentially switched to ch1, ch2,. The received signal of the selected channel is selected and applied to the recording signal processing unit 9 via the switching unit 8. After the last channel chN set so as to be selectable with the channel button 22, LINE, that is, the external input terminal 2 is selected. At this time, the switching section 8 at the preceding stage of the recording signal processing section 9 in FIG. 1 is switched so as to select the external input terminal 2.
[0028]
When a plurality of external input terminals 2 are provided, the selection of LINE may be further switched to LINE1 and LINE2 sequentially. Pressing the + button after the selection of LINE returns to the state of selecting the first channel ch1. When the-button of the channel button 22 is pressed, the signals to be applied to the recording signal processing unit 9 are switched in the reverse order of the pressing of the + button.
[0029]
In FIG. 3, a "navigation" button 23 is a button for displaying a screen for selecting a video signal to be reproduced on a display, which will be described in detail later. The button 24 is used to search for a desired thumbnail, and the button 25 is used to move the selected position of the thumbnail on the screen in that direction by pressing one of the four buttons in the up, down, left, and right directions. Button and the center circular button are OK buttons for confirming the selection. When the remote controller 20 is operated, a remote control signal of a code corresponding to the operation content is transmitted from the infrared light emitting unit 26 in the form of infrared light.
[0030]
Next, recording and reproducing operations and the operation of the recording and reproducing apparatus of the present embodiment at that time will be described. Although there are operations using screens displayed on the display (calendar screen, thumbnail list screen, and the like), detailed descriptions of these screens will be described later by dividing the items.
[0031]
[Recording operation and operation]
Hereinafter, an example of an operation at the time of recording a video signal by the recording and reproducing apparatus 1 and an operation at that time will be described. FIG. 5 is a flowchart showing an example of two types of recording operations recorded as different categories A and B on the HDD 10 among the operations by the remote controller 20.
[0032]
First, the microprocessor 11 in the recording / reproducing apparatus determines whether or not the REC button and the PLAY button among the buttons 21 of the remote controller 20 shown in FIG. When detecting that the REC button and the PLAY button are simultaneously pressed (step S1), the video signal of the selected channel is recorded on the hard disk in the HDD 10 (step S2).
[0033]
At this time, this video signal is recorded as Class B of Classes A and B. At the time of reproduction, a video signal belonging to this "class B" is selected on a thumbnail list screen of two reproduction selection screens described later. If LINE is selected as a channel when the REC button and the PLAY button are pressed simultaneously, a video signal input via an external input terminal is recorded.
[0034]
Classifications A and B can be distinguished in the TOC information at the time of recording, recorded as additional information together with the video signal to be recorded, or divided into two video signal recording areas in the HDD 10 and It can be distinguished by a method such as a dedicated recording area for video signals belonging to Class A and Class B.
[0035]
On the other hand, if it is not detected in step S1 that the REC and PLAY buttons have been pressed simultaneously, the microprocessor 11 detects whether or not the "navi" button 23 has been pressed on the remote controller 20 (step S3). If the "navigation" button 23 is not detected, it is detected whether or not another operation has been performed (step S4). If another operation has been performed, an operation corresponding to the operation is performed. If no other operation has been performed, the flow returns to step S1 to determine again whether the REC and PLAY buttons have been pressed simultaneously.
[0036]
When detecting that the "navigation" button 23 has been pressed in step S3, the microprocessor 11 displays the navigation screen of the previous operation on the display 19 (step S5). The navigation screen includes a calendar screen, a thumbnail list screen, and the like, as described later, and can be selected by a user operation. Here, when the display of the navigation screen is completed, information indicating what the navigation screen is at that time is recorded in the nonvolatile RAM or the HDD 10 in the recording / reproducing apparatus, and the navigation screen displayed immediately before this time is displayed. The screen is displayed. In step S5, a specific screen may be displayed first such that a calendar screen is always displayed first.
[0037]
Next, it is determined whether or not this screen is a calendar screen (step S6). If the screen is not a calendar screen, it is determined whether or not a change operation to the calendar screen has been performed (step S7). When the change operation is performed, a calendar screen is displayed on the display 19 (step S8). If no change operation to the calendar screen is detected (step S7), it is determined whether another operation has been performed (step S9), and if another operation has been performed, a process corresponding thereto is performed. If the above operation is not performed, the process returns to step S6.
[0038]
If it is detected in step S6 that the screen is a calendar screen, or if the calendar screen is displayed in step S8, it is detected whether or not "movie capture" in the calendar screen described later has been selected (step S10). . When it is detected that "movie import" is selected, the video signal input to the external input terminal 2 is recorded on the hard disk in the HDD 10 as the classification A (step S11). The video signal belonging to the “category A” is selected at the time of reproduction on a calendar screen of a reproduction selection screen described later. It should be noted that a specific operation when “movie import” is selected will be described later.
[0039]
If the selection instruction of "take movie" is not detected in step S10, it is detected whether or not another operation has been performed (step S12). When another operation is performed, an operation corresponding to the operation is performed. If this detection is not performed, the process returns to step S10, and the detection operation of the selection instruction of “movie import” is repeated.
[0040]
Here, recording of date information related to the calendar screen display will be described. The date information is generally given to a file of an image to be recorded in a digital camera, and the date of still image information stored in a memory card is given to the file. It may be read and used when recording in the. Even in a camera-integrated recorder, date information is recorded as additional information at the time of recording, and when the date is taken into the HDD, the information may be taken into the HDD at the same time as the video signal.
[0041]
When capturing from the camera-integrated recorder is performed using an analog video signal, date information can be inserted and transmitted in a vertical blanking period or the like, but generally, date information is not transferred. At this time, the date fetched into the HDD may be used as preset date information so that the user can appropriately change the date information before or after recording the video signal during recording.
[0042]
As described above, the case where the REC button and the PLAY button are simultaneously pressed on the remote controller 20 and the case where the “movie capture” on the calendar screen is selected and instructed as the recording operation has been described. A timer reservation is made with a remote controller, and recording is automatically started when the reserved time comes, or a program reservation is made using EPG (Electronic Program Guide) information transmitted in digital broadcasting. There is also.
[0043]
Still images are also taken from a memory card. These are recorded as category A in the case of a video or the like shot by the user himself, and recorded as category B in the case of a television broadcast program or the like. Then, when the user wants to play back, the program recorded as category A is selected on selection screen A (calendar screen), and the program recorded as category B is selected on selection screen B (thumbnail list screen). These are shown in FIG.
[0044]
[Playback operation and operation]
Next, the reproducing operation and the operation of the present embodiment will be described. FIG. 7 is a flowchart for explaining a reproducing operation method and operation of the video signal recording / reproducing apparatus according to one embodiment of the present invention. Steps related to operations common to the operations shown in FIG. 5 are denoted by the same reference numerals. In FIG. 7, since the selection of the video signal to be reproduced is performed on the navigation screen, the microprocessor 11 detects the display of the navigation screen in steps S3 to S5 similar to a part of FIG. Next, the display of the calendar screen is detected by a series of steps from step S6 to step S8, which is also similar to a part of FIG.
[0045]
When the operation for changing to the calendar screen is not performed instead of the calendar screen, the microprocessor 11 detects whether or not the screen is the thumbnail list screen (step S24). If it is not the thumbnail list display screen, it is detected whether or not an operation for changing to the thumbnail list screen has been performed (step S25). If not, it is detected whether or not another operation has been performed (step S25). S26). If another operation has been performed, the process of that operation is performed. If no other operation has been performed, the process returns to step S6, and it is determined again whether or not the screen is the calendar screen.
[0046]
When the calendar screen is detected in step S6 or when the calendar screen is displayed in step S8, the display 19 displays the calendar screen. At this time, the microprocessor 11 detects whether or not a section of the date in the calendar has been selected (step S21).
[0047]
If the instruction to select the date section is not detected, it is detected whether or not another operation has been performed (step S22). If another operation has been performed, the processing of that operation is performed, and another process is performed. If no operation has been performed, the flow returns to step S21, and it is detected again whether or not a section of the date in the calendar has been selected and instructed. Here, although not shown in FIG. 7, if the “other operation” in step S22 is a change operation to the thumbnail list screen, a thumbnail list screen is displayed on the display 19, and a step S28 described later is performed. The following processing is performed.
[0048]
On the other hand, when the microprocessor 11 detects in step S21 that one of the sections of the date has been selected and instructed, it reproduces the video signal recorded with the date information corresponding to the section from the hard disk in the HDD 10. (Step S23). Each date may include both a moving image video signal recorded by a camera-integrated recorder or the like and a still image video signal captured by a digital camera or the like. Also, a plurality of video signals may be registered on this date in a moving image or a still image. Therefore, actually, a screen for selecting a desired one from the video signals on this date is displayed, and the user selects from the screen. The details will be described later in the description of the navigation screen.
[0049]
Next, when it is detected in step S24 that the screen is the thumbnail list screen, or when a change operation to the thumbnail list screen is performed in step S25 and the thumbnail list screen is displayed in step S27, the process proceeds to step S28. Detects whether one of the thumbnails has been selected. If no thumbnail has been selected, it is detected whether or not another operation has been performed (step S29). If another operation has been performed, processing corresponding to that operation is performed. Here, although not shown in the figure, if this "other operation" is an operation for changing to the calendar screen, the calendar screen is displayed on the display 19, and the processing from step S21 is performed. If no other operation is detected in step S29, the process returns to step S28. When one of the thumbnails is selected and instructed by a user operation in step S28. The microprocessor 11 reproduces the video signal of the program represented by the thumbnail from the hard disk in the HDD 10 and displays it on the display 19 (Step S30).
[0050]
[Navigation screen 1 Calendar screen]
Next, the calendar screen will be described. FIG. 8 shows an example of a calendar screen in the navigation screen. There are four types of screen menu tabs 31 to 34 in the upper part of the drawing. Here, a tab 31 of a picture of the digital camera and the recorder integrated with the camera is selected, and this represents a calendar screen. The picture tab 32 of the television receiver represents a thumbnail list display screen, which will be described later. When the user selects and instructs this, a thumbnail list display screen is displayed instead of the calendar screen.
[0051]
In addition, here, it is assumed that music information of only audio can be recorded on the HDD, so that a user who is accustomed to the operation of the recording / reproducing apparatus and the tab 33 of the screen for selecting the music information is more user-friendly. As described above, the tab 34 on the operation screen for customizing the recording / reproducing apparatus can be selected. The latter two are not directly related to the present invention and will not be described.
[0052]
Here, the user's selection instruction on the navigation screen is, for example, that four keys arranged around the circular shape of the button 25 of the remote controller 20 shown in FIG. Then, the selected item on the screen is sequentially moved, and when a certain item is selected and the user designates the item, a circular OK button in the center of the button 25 may be pressed. Other well-known human interfaces, such as using a mouse commonly used in personal computers, mounting a touch tablet often used in notebook computers on a remote control, or using a joystick, etc. May be used as appropriate.
[0053]
In FIG. 8, a calendar for a certain month (here, October 2002) is displayed. Here, if there is a still image taken by a digital camera or the like to which the date is attached, an icon (small image for visual recognition) 35 representing the digital camera is displayed at the date on the calendar, and the date is displayed. If there is a moving image captured by the assigned camera recorder or the like, an icon 36 representing the camera recorder is displayed. If both are present (October 2, 5, 7, 26, 2002), both are displayed. That is, when displaying the calendar, the content of the TOC information of the HDD may be analyzed, a video signal to which the date is assigned may be searched and displayed at each date of the calendar.
[0054]
Here, only the video signal recorded as Class A at the time of recording is displayed for each date on the calendar, and the video signal such as a television broadcast program recorded as Class B at the time of recording is displayed. Even if there is a program recorded on that day, its existence is not displayed here, and the program recorded in Class B cannot be reproduced in the alteration through this screen.
[0055]
In FIG. 8, a move to previous month button 37, a move to next month button 38, a move to previous week button 39, and a move to next week button 40 are arranged on the screen, and select and instruct them. Can be used to move the calendar portion to be displayed. When a calendar for this month is desired to be displayed, this can be performed by selecting and instructing a “to this month” button 41 at the upper left. In the display space 42 below the calendar, characters serving as guides for operating methods are displayed, so that even a beginner can use it easily. For example, when “October 2” is selected, “View image of October 2” is displayed. If that is okay, the user can perform the operation by performing a confirmation operation such as pressing an OK button.
[0056]
The button 43 of the "recollection album" is a button that allows the user to make a selection instruction in addition to the selection from the date of the calendar, and registers and displays the image contents and the like regarding the video important for the user. By directly selecting and instructing this button 43 on the screen, the video can be easily read. Here, since the date of five weeks is displayed on the month calendar screen, a series of memories images are arranged in order on the button 43 of the "recollection album" using the contents of the five weeks as a material. Register a still image and moving image mixed image collection.
[0057]
Since the area of the screen of the month calendar is limited, the number of “memorial albums” that can be registered is limited, for example, about 3 to 4/5 weeks. If there is no registered memory album, this button 43 is not displayed on the screen. Here, when the month of the month calendar is changed or the week is changed, another memory album list appears in conjunction with the change.
[0058]
For example, in FIG. 8, the dates from September 29 to November 2 are displayed, but a memory album having a “start date” during that period appears as a button 43.
