Is provided. The display unit 101 is, for example, a liquid crystal display or an organic EL display, and may function as an operation unit by providing an input function as a touch panel. Details of functions of the operation unit 102, the controller wheel 103, and the mode changeover switch 104 will be described later with reference to FIG.

  On the top surface of the digital camera 100, a shutter button 121 for instructing photographing and a power switch 122 for switching the power on / off of the digital camera 100 are provided. Details of the function and the like of the shutter button 121 will be described later with reference to FIG.

  An external device can be connected to the side surface of the digital camera 100 via the connection cable 111 and the connector 112, and the digital camera 100 outputs image data (still image data, moving image data) to the external device. Be able to. A storage medium slot (not shown) that can be opened and closed by a lid 131 is provided on the lower surface of the digital camera 100, and a storage medium 130 such as a memory card can be inserted into and removed from the storage medium slot. Yes.

  The storage medium 130 stored in the storage medium slot can communicate with the control unit of the digital camera 100 (system control unit 210 described with reference to FIG. 2). The storage medium 130 is not limited to a memory card that can be inserted into and removed from the storage medium slot, but may be an optical disk such as a DVD-RW disk or a magnetic disk such as a hard disk. It may be built in the main body.

<Hardware configuration of digital camera>
FIG. 2 is a block diagram illustrating a hardware configuration of the digital camera 100. The digital camera 100 includes a barrier 201, a photographing lens 202 that constitutes an imaging optical system, a shutter 203, and an imaging unit 204. The barrier 201 covers the imaging optical system to prevent the imaging optical system from being soiled or damaged. The photographing lens 202 is constituted by a lens group including a zoom lens and a focus lens. The shutter 203 has a diaphragm function and adjusts the exposure amount. The imaging unit 204 is an imaging element that converts an optical image into an electrical signal (analog signal), and for example, a CCD or a CMOS element is used.

  In the digital camera 100, an analog signal is output from the imaging unit 204 to the A / D converter 205. The A / D converter 205 converts the received analog signal into a digital signal and outputs the digital signal to the image processing unit 206 or the memory control unit 207. The image processing unit 206 performs predetermined resizing processing such as pixel interpolation and reduction, color conversion processing, and the like on the data (digital signal) received from the A / D converter 205 or the data received from the memory control unit 207. The image processing unit 206 performs predetermined calculation processing using the image data of the captured image, and the system control unit 210 performs exposure control and distance measurement control using the calculation result thus obtained. For example, the system control unit 210 performs TTL (through the lens) AF (autofocus) processing, AE (automatic exposure) processing, and EF (flash pre-flash) processing. The image processing unit 206 further performs predetermined calculation processing using the image data of the captured image. Based on the obtained calculation result, the system control unit 210 performs TTL AWB (auto white balance) processing. Do.

  Output data from the A / D converter 205 is written into the memory 209 via the image processing unit 206 and the memory control unit 207 or via the memory control unit 207. In addition to this, the memory 209 stores image data to be displayed on the display unit 101. The memory 209 has a sufficient storage capacity capable of storing a predetermined number of still images, a moving image for a predetermined time, and audio data. The memory 209 also serves as an image display memory (video memory).

  The image display data (digital data) stored in the memory 209 is transmitted to the D / A converter 208. The D / A converter 208 converts the received digital data into an analog signal and supplies the analog signal to the display unit 101, whereby an image is displayed on the display unit 101. As described above, the display unit 101 is a display such as a liquid crystal display, and displays an image based on an analog signal from the D / A converter 208. A digital signal converted into a digital signal by the A / D converter 205 and stored in the memory 209 is converted into an analog signal by the D / A converter 208 and sequentially transferred to the display unit 101 for display. The electronic viewfinder function can be realized. That is, the through image display can be performed in this way.

  The digital camera 100 includes a non-volatile memory 211 such as an EEP-ROM, which is an electrically erasable and memorable memory. The non-volatile memory 211 includes a program executed by the system control unit 210 and an operation memory. Are stored. The system control unit 210 controls the overall operation of the digital camera 100 by executing various programs stored in the non-volatile memory 211. As an example, the system control unit 210 relates to the flowchart shown in FIG. Execute the process. Programs, operation constants, variables, and the like read from the nonvolatile memory 211 by the system control unit 210 are expanded on the system memory 213. A RAM is used as the system memory 213. Furthermore, the system control unit performs display control by controlling the memory 209, the D / A converter 208, the display unit 101, and the like.

  The digital camera 100 includes a system timer 212 that measures the time used for various controls and the time of a built-in clock. The operation unit 102, controller wheel 103, shutter button 121, mode switch 104, and power switch 122 shown in FIG. 2 are the same as those described with reference to FIG.

  Various operation members constituting the operation unit 102 are used for selecting various function icons displayed on the display unit 101, and functions are appropriately assigned to each scene by selecting a predetermined function icon. It is done. That is, each operation member of the operation unit 102 functions as various function buttons. Examples of the function buttons include an end button, a return button, an image advance button, a jump button, a narrowing button, an attribute change button, and a DISP button. For example, when a menu button is pressed, a menu screen for performing various settings is displayed on the display unit 101. The user can intuitively perform the setting operation using the menu screen displayed on the display unit 101 and the four-way buttons and the SET button.

  A controller wheel 103, which is an operation member capable of rotating, is used when a selection item is instructed together with a four-way button. When the controller wheel 103 is rotated, an electrical pulse signal corresponding to the operation amount (rotation angle, number of rotations, etc.) is generated. The system control unit 210 analyzes the pulse signal and controls each unit of the digital camera 100. The controller wheel 103 may be any operation member that can detect a rotation operation. For example, a dial operation member that generates a pulse signal by rotating the member itself in accordance with a user's rotation operation may be used. In addition, a so-called touch wheel may be used that detects an operation of rotating a user's finger on the operation member without rotating the operation member itself by an operation member made of a touch sensor.

  The shutter button 121 includes a first switch SW1 and a second switch SW2. The first switch SW <b> 1 is turned on when the shutter button 121 is half-pressed while the shutter button 121 is being operated. When the system control unit 210 receives a signal indicating that the first switch SW1 is turned on, the system control unit 210 starts operations such as AF processing, AE processing, AWB processing, and EF processing. The second switch SW2 is turned on when the shutter button 121 is fully pressed, and a signal instructing to start photographing is thereby transmitted to the system control unit 210. When receiving a signal with the second switch SW2 turned ON, the system control unit 210 performs a series of shooting operations from reading a signal from the imaging unit 204 to writing image data into the storage medium 130.

  The mode switch 104 is a switch for switching the operation mode of the digital camera 100 between various modes such as a still image storage mode, a moving image storage mode, and a playback mode. The still image storage mode includes, for example, an auto shooting mode, an auto scene determination mode, a manual mode, various scene modes serving as shooting settings for each shooting scene, a program AE mode, a custom mode, and the like. By operating the mode switching switch 104, it is possible to directly switch to one of these modes included in the still image shooting mode. However, the present invention is not limited to such a configuration. For example, after switching to the still image shooting mode with the mode switch 104, the operation mode is switched to one of the above modes included in the still image shooting mode using another operation member. You may do it. Similarly, the moving image shooting mode may include a plurality of modes.

  The digital camera 100 includes a power supply unit 214 and a power supply control unit 215. The power supply unit 214 is a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, or an AC adapter, and supplies power to the power supply control unit 215. The power supply control unit 215 is configured by a battery detection circuit, a DC-DC converter, a switch circuit that switches an energization block, and the like. The power supply control unit 215 detects the presence / absence of the battery in the power supply unit 214, the type of battery, the remaining battery level, etc., and controls the DC-DC converter based on the detection result and the instruction of the system control unit 210, and is necessary A sufficient voltage is supplied to each part including the storage medium 130 for a necessary period.

  The digital camera 100 includes a storage medium I / F 216 that enables communication between the storage medium 130 and the system control unit 210 when the storage medium 130 is mounted in a storage medium slot (not shown). The details of the storage medium 130 have already been described with reference to FIG.

<Movie digest mode>
The digital camera 100 can shoot in the movie digest mode. In the movie digest mode, for example, for one or a plurality of still images taken within a predetermined period such as every day, a moving image (hereinafter referred to as “digest moving image”) for a predetermined time immediately before each still image is shot. Is done. A moving image file in which each digest moving image is linked is stored in association with each still image. Therefore, in the movie digest mode, one or more still images are associated with one moving image file.

  In movie digest mode, a movie file of the digest movie is generated when the first still image is shot within the specified period, and the file name is not changed thereafter. Digest video will be added to. It should be noted that a moving image file of a digest moving image is appended unless the file capacity or the time of the entire moving image exceeds a predetermined value as the capacity or time of one digest moving image. Therefore, basically, only one moving image file is stored in a predetermined period. Such shooting control and storage control are executed by the system control unit 210.

  By operating the mode switch 104, the operation mode of the digital camera 100 can be set to the movie digest mode. When the system control unit 210 receives the ON signal of the first switch SW1 in the movie digest mode, the system control unit 210 starts moving image shooting processing and controls the memory control unit 207 to store the moving image obtained by shooting in the memory 209. The longest time of the digest video stored in the memory 209 is set to a predetermined time such as 4 seconds, for example. Therefore, when the digest video time stored in the memory 209 exceeds the maximum time, the system control unit 210 controls the memory control unit 207 so that the captured time is deleted in order from the oldest frame. To do.

  When receiving the ON signal of the second switch SW2 that is a shooting instruction, the system control unit 210 stops writing the moving image to the memory 209 and stores the moving image stored in the memory 209 as the digest moving image in the storage medium 130. . At this time, the system control unit 210 determines whether the digest moving image to the storage medium 130 via the storage medium I / F 216 depends on whether there is a moving image file of the digest moving image already stored in the same predetermined period in the storage medium 130. Different storage methods.

  That is, when there is no digest movie file stored in the same predetermined period, the system control unit 210 causes the newly-captured digest movie to be stored in the storage medium 130 as a new file. At this time, an image ID indicating the playback order at the time of browsing is assigned, but a new file of a digest video is assigned a smaller number than a still image file shot by an ON signal of the second switch SW2. . In addition, when there are digest video files stored in the same predetermined period, the system control unit 210 concatenates and stores the newly stored digest video as a continuation of the existing digest video file. .

  That is, when a still image is shot a plurality of times in the movie digest mode, first, a digest movie for a predetermined time before shooting the first still image is stored in the storage medium 130, and then associated with the digest movie. A still image is stored. For the second and subsequent still image shooting, a digest video for a predetermined time before shooting the still image is added to the previously stored video file. Therefore, the order of the files managed in the storage medium 130 is that the moving image file starts at the top, and then one or more still images associated with the moving image file are stored as image files.

  In the digest movie video file stored in the storage medium 130, attribute information indicating that the movie file is a digest movie video file is added to the header image or the thumbnail image file associated with the movie file. Shall be. In addition, an identifier indicating an image file of a still image related to shooting that is a trigger for storing a moving image portion included in the moving image file, and information indicating a moving image portion corresponding to each still image (for example, a time code, a chapter number, The correspondence of the identifier of the still image) is stored in the storage medium 130.

  On the other hand, an image file of a still image shot in the movie digest mode is added with an identifier indicating that it was shot in the movie digest mode, and is stored in the storage medium 130. An image file of a still image shot in the movie digest mode is associated with an identifier (file name, file number, unique ID, etc.) indicating a moving image file having a digest moving image portion stored by shooting the still image. Memorized. These pieces of information are stored, for example, in the header portion of the still image file. Further, information (time code, chapter number, etc.) indicating the digest moving image portion stored by shooting the still image among the moving images of the moving image file associated with the still image shot in the movie digest mode is also stored.

<Display control>
FIG. 3 is a flowchart of display control in the digital camera 100. This flowchart is for displaying guidance on the display unit 101 indicating how to play back a digest video stored in association with a still image when viewing a still image shot in the movie digest mode in the single playback mode. The flow of processing is shown. The single reproduction mode refers to an image display mode in which one image is displayed on the entire display area of the display unit 101 in a maximum size that can accommodate the entire image (full screen display).

  The processing of each step shown in FIG. 3 is realized by the system control unit 210 developing and executing a program stored in the nonvolatile memory 211 in the system memory 213.

  When the single playback mode is set in the digital camera 100, the system control unit 210 reads an initial display image from the storage medium 130 and performs full screen display on the entire display area of the display unit 101. Note that, as the initial display image, for example, an image that was last displayed during playback in the previous single playback mode, or an image that was recently taken in time is displayed. FIG. 4A shows an example of a state in which an initial display image is displayed on the display unit 101. 4A is a table when the information display mode in the digital camera 100 is “non-display mode” in which information display is not performed (that is, the information amount displayed on the display unit 101 is the smallest). It is an example.

  When the image reproduction in the single reproduction mode is started, the system control unit 210 monitors an operation input from the user and executes a process according to the operation input. Note that the determinations in steps S301, S308, S310, S312, and S314 shown in FIG. 3 are not limited to this order, but are performed simultaneously in parallel.

  The system control unit 210 determines whether or not there is an image forwarding instruction (for example, pressing the right button or the left button of the cross button included in the operation unit 102) (step S301). If the system control unit 210 determines that image feed has been instructed (YES in S301), the process proceeds to step S302; otherwise (NO in S301), the process proceeds to step S308.

  In step S302, the system control unit 210 executes image feed processing. That is, the next or previous image corresponding to the operation content in step S301 is read from the storage medium 130, and the read image is displayed on the display unit 101 instead of the currently displayed image. At that time, if the timer started in step S307, which will be described later, is being counted, the counting is stopped and the timer is cleared (initialized).

  After step S302, the system control unit 210 determines from the image header information whether or not the image displayed in step S302 is a still image shot in the movie digest mode (step S303). If the system control unit 210 determines that the image is a still image shot in the movie digest mode (YES in S303), the process proceeds to step S304; otherwise (NO in S303), the process returns to step S301.

  In step S <b> 304, the system control unit 210 determines whether there is a digest movie (hereinafter referred to as “related movie”) associated with the displayed image in the storage medium 130. This process can be executed by referring to the header information of the image file of the displayed image. Or, analyze all the headers of the digest video in advance, prepare index information that writes out the identifier of the still image file related to the digest video in advance, and whether the displayed image file matches the index information You may determine by no. If the system control unit 210 determines that there is a related moving image (YES in S304), the process proceeds to step S305; otherwise (NO in S304), the process returns to step S301.

  In step S <b> 305, the system control unit 210 displays guidance for guiding an operation for reproducing the related moving image on the display unit 101. FIG. 4B is a diagram illustrating an example of a screen displayed on the display unit 101 in step S305. In FIG. 4B, an image different from that in FIG. 4A is displayed by the image forwarding process in step S302. 4B, the related moving image exists in the storage medium 130, and the related moving image can be reproduced by performing a specific operation of pressing the SET button included in the operation unit 102 once. A guidance 401 indicating that this is superimposed on the upper left of the screen.

  After step S305, the system control unit 210 determines whether or not the current information display mode is a non-display mode (step S306). If the current information display mode is the non-display mode (YES in S306), the system control unit 210 advances the process to step S307. If not (NO in S306), the system control unit 210 returns the process to step S301. In step S307, the system control unit 210 activates a timer that measures the time until the guidance 401 is not displayed. The default value of the time until the guidance 401 is not displayed is set in advance when the digital camera 100 is manufactured, but can be changed by operating the operation unit 102. After step S307, the system control unit 210 returns the process to step S301.

  Here, as described above, the determinations in steps S301, S308, S310, S312, and S314 are simultaneously performed in parallel. Therefore, the system control unit 210 determines whether or not the timer activated in step S307 has expired (time up) (step S310). When the timer expires (YES in S310), the system control unit 210 deletes the guidance 401 from the screen (step S311). FIG. 4C is a diagram showing an example of a screen displayed on the display unit 101 in step S311, and shows a state where the guidance 401 is hidden and only the image is displayed. After step S311, the system control unit 210 returns the process to step S301.

  Note that the timer starts only when it is determined in step S306 that the information display mode is the “non-display mode”. Therefore, when the information display mode is a mode other than the non-display mode, the guidance 401 is maintained in a displayed state without being erased from the screen over time.

  In step S308, the system control unit 210 determines whether there is an input for switching the information display mode (for example, pressing a DISP button included in the operation unit 102). For example, each time the DISP button is pressed, the information display mode is sequentially switched in the order of “non-display mode”, “simple information display mode”, “detailed information display mode”, and “non-display mode”. The amount of information displayed on the display unit 101 is in the order of non-display mode <simple information display mode <detailed information display mode.

  When the information display mode is not switched (NO in S308), the system control unit 210 advances the process to step S310. On the other hand, if the information display mode has been switched (YES in S308), the system control unit 210 switches the information display mode in accordance with the operation (step S309), and then the process proceeds to step S303. Note that the system control unit 210 stops and clears (initializes) the timer when executing the process of step S309 when the timer is activated and counting is being performed by the process of step S308.

  FIG. 4D is a diagram showing an example of a screen displayed on the display unit 101 when the “simple information display mode” is set. The file number 402, the image size, and the compression are superimposed on the image. The image quality information 403 indicating the rate, the shooting date / time information 404, and the like are displayed. FIG. 4E is a diagram illustrating an example of a screen displayed on the display unit 101 when the “detailed information display mode” is set. In the “detailed information display mode”, in addition to the information displayed in the “simple information display mode” superimposed on the image, details such as the histogram 405, shutter speed / ISO sensitivity / aperture value (F value) / white balance, etc. Information 406 and the like are displayed. In both the “simple information display mode” and the “detailed information display mode”, the guidance 401 is also displayed when there is a related moving image of the displayed image, but there is no related moving image of the displayed image. In this case, the guidance 401 is not displayed.

  After the process of step S309, the system control unit 210 advances the process to step S303. Therefore, even when the guidance 401 is not displayed before the information display mode is switched, when the information display mode is switched, if there is a related video regardless of the information display mode after the switching, this is indicated. Guidance 401 will be displayed. When the “non-display mode” is set, the guidance 401 is displayed only for a predetermined time and then is not displayed.

  In step S310, the system control unit 210 determines whether or not the timer activated in step S308 has counted the set predetermined time. If the predetermined time has not elapsed (NO in S310), system control unit 210 advances the process to step S312. On the other hand, when the predetermined time has elapsed (YES in S310), the system control unit 210 deletes the guidance 401 from the screen as shown in FIG. 4C to display only the image, and then returns the process to step S301. .

  Therefore, when the information display mode is switched in step S309, the guidance 401 is displayed. However, when the information display mode is the non-display mode, the guidance 401 is not displayed after a certain period of time by the timer count. Is done. On the other hand, when the information display mode is switched to a mode other than the non-display mode in step S309, the guidance 401 is not automatically hidden even if a predetermined time by the timer count elapses. . Even when a certain time has elapsed since the guidance 401 was displayed, the guidance 401 may be hidden without waiting for the elapse of a predetermined time when a specific operation is performed. Good.

  In step S312, the system control unit 210 determines whether there is an instruction to play a related moving image. That is, it is determined whether or not the SET button has been pressed when an image containing a related moving image is displayed. If an image containing a related moving image is displayed, it is assumed that, even after the guidance 401 is deleted, if the SET button is pressed, a related moving image is instructed to be reproduced. If there is an instruction to play a related video (YES in S312), system control unit 210 advances the process to step S313, and if not (NO in S312), advances the process to step S314.

  In step S313, the system control unit 210 reads the related moving image of the still image from the storage medium 130, reproduces the related moving image (step S313), and then returns the process to step S301. At this time, when a related video playback instruction is given in a state where a still image with no related video is displayed, no processing may be performed, and a warning message indicating that there is no related video is displayed. It is good also as a structure which notifies a warning, such as displaying.

  In step S314, the system control unit 210 determines whether there has been another input operation (an input operation other than S301, S308, and S312). Other input operations include the transition to the enlarged playback mode for enlarging the displayed still image, the transition to the multi playback for displaying multiple images, the input operation for instructing the display of the menu screen or the end of the playback mode, etc. Can be mentioned. When there is no other input operation (NO in S314), the system control unit 210 returns the process to step S301, and when there is another input operation (YES in S314), the system control unit 210 executes a process instructed by the input operation. (Step S315). Thereafter, the system control unit 210 returns the process to step S301.

  As is clear from the above description, when the SET button is pressed twice in a state where a still image with a related moving image is displayed, the system control unit 210 instructs the reproduction of the related moving image for the second time. It is determined that another process is instructed. Therefore, it is necessary to issue a related moving image reproduction instruction by a single operation of the SET button. In addition, when the single playback mode is set again from a mode other than the single playback mode, it is necessary to execute the image forwarding process in order to display the image again. 401 is displayed.

<Modification of display control>
In the above-described embodiment, the configuration has been described in which the execution of the image forwarding process is used as a trigger to determine the presence or absence of a related moving image with respect to a still image to be displayed, and to display guidance indicating the method of reproducing the related moving image. In this case, if the still images stored in the storage medium 130 are only still images taken in the movie digest mode, guidance indicating the same information is displayed every time the image is fed, so that the image can be viewed. There is a risk of reducing the sex. Therefore, the following configuration reduces the deterioration of the image browsing property.

  In other words, when the still image before sending the image is shot in the movie digest mode and the guidance 401 is displayed because there is a related video, the still image after sending the image similarly displays the guidance 401. If the condition is satisfied, the guidance 401 is not displayed during the image feed process. However, in this case, it is difficult for the user to understand whether the guidance 401 is not displayed when image forwarding is executed because there is a related moving image or not. Therefore, when the still image before image sending is shot in the movie digest mode, and it is determined that there is a related video and the guidance 401 is displayed, and there is no related video in the still image after image sending The guidance indicating that there is no related video is displayed. In addition, when the still image on which the guidance 401 is displayed is image forwarded / returned and redisplayed (after another image is displayed by image forwarding from that image, the image is displayed again by image returning. In such a case, the guidance 401 may not be displayed.

  In the above embodiment, video (image, video) is output and displayed on the display unit 101 of the digital camera 100. On the other hand, it is conceivable that video is output from the digital camera 100 to an external display device via the connector 112 and the connection cable 111 and displayed. In this case, the user seeks higher viewability. It is thought that there is. Therefore, in this case, the guidance 401 may not be displayed according to the image feed regardless of whether or not the digest video is associated and regardless of which information display mode is set. it can. Such control may be performed by the system control unit 210 or may be executed by separately providing output control means for the display device.

  In the above embodiment, the related moving image of the still image shot in the movie digest mode has been described as an example of the related file associated with the predetermined still image. However, the present invention is not limited to this, and if there is an audio file (such as an audio memo) associated with the displayed image, the associated audio file is handled and processed in the same manner as the related video in the above embodiment. It may be. In addition, when the displayed image is a still image (still image during moving image) captured by a still image shooting instruction performed during moving image shooting, the moving image captured at the time of shooting the still image is It may be handled and processed in the same manner as the related video.
