  The storage unit 18 is an area for storing normal image data, music data, and the like, as well as image data acquired by shooting, and an image for slide show reproduction generated by image processing by the synthesis processing unit 24 and the image processing unit 16. It has a display temporary storage area 18a for temporarily storing data, and a music temporary storage area 18b for storing BGM music data used for slide show reproduction.

  The display control unit 19 causes the display unit 20 to display a monitor image, which is a display image generated by the image processing by the image processing unit 16, at the time of shooting. The display control unit 19 causes the display unit 20 to display an image read from the storage unit 18 and decompressed by the image processing unit 16 during image reproduction.

  The communication unit 21 is an interface for exchanging data such as image data and music data with an external device such as a server capable of communicating via an external PC or a network.

  The face detection unit 22 includes, for example, a position detection unit 22b that detects the position of a face such as a person in a captured image displayed on the display unit 20 or image data acquired by shooting, and the position detection unit 22b. And a size detecting unit 22a for detecting the size of the face portion whose position is detected. In this way, the face detection unit 22 detects information regarding the face of the subject.

  Hereinafter, slide show reproduction, which is one of the main features of the digital camera according to the present embodiment, will be described.

  FIG. 2 is a graph example in which the horizontal axis indicates the shooting date and time, and the vertical axis indicates the number of image data acquired by shooting. That is, the graph shown in FIG. 2 is an example of a graph showing variation in photographing frequency.

  In FIG. 2, the number of image data obtained by photographing one day in six time zones (referred to as first time zone, second time zone,..., Sixth time zone in order) Is expressed by expressing one image by one square.

  Further, in FIG. 2, image data in which the main subject is a person (hereinafter referred to as person image data) is distinguished from image data other than the person as the main subject (hereinafter referred to as general image data). Represents. In other words, the hatched squares indicate the person image data, and the open squares indicate the general image data.

  In the example shown in FIG. 2, as an event, an athletic meet is held on 9/21, a wedding is held on 9/25, and the number of image data acquired on 9/20 is 0. The number of image data acquired by shooting is 18.

  More specifically, the breakdown of the image data acquired by photographing on 9/21 is as follows: 1 person image data in the first time zone, 5 person image data in the second time zone, and general image data 2 images, 5 human image data and 2 general image data in the third time zone, 2 human image data in the 4th time zone, 1 general image data in the 5th time zone is there.

  Thus, if it is a general user, the number of image data acquired by photography will differ greatly every photography day. In addition, since such a variation in the number of shots usually has a certain pattern, it can be determined with a certain degree of accuracy in what event the image data acquired by shooting was shot. It becomes possible.

  Then, by determining the event in which the image data is captured, it is possible to automatically determine appropriate music data to be reproduced simultaneously with the slide show reproduction of the image data. FIG. 3 is a diagram showing a flowchart of processing by the camera control unit 10 (mainly the classification unit 10a) that automatically determines music data to be simultaneously reproduced when performing slide show reproduction of image data.

  Here, for convenience of explanation, the process of determining the event in units of one day will be described. However, the event is not necessarily in units of one day, and of course, the event may be determined in shorter units or longer units.

  First, the classification unit 10a classifies the image data stored in the storage unit 18 into the first time zone to the sixth time zone based on the shooting time of the image data (step S1).

  Subsequently, the classification unit 10a determines whether the image data classified in step S1 is concentrated in any one of the first to sixth time zones on a predetermined date. Is determined (step S2). This determination is a determination using the fact that, for example, in travel, the number of times of shooting is likely to be dispersed in each time zone of the day.

  When step S2 is branched to YES, the classification unit 10a determines whether or not the ratio of the image data in which the face portion is up is smaller than a predetermined ratio (step S3). When step S3 is branched to YES, it is determined that the event in which the image data is captured is a “school event” such as an athletic meet (step S4). On the other hand, when step S3 is branched to NO, the classification unit 10a determines that the event in which the image data is captured is “party” (step S5).

  By the way, when step S2 is branched to NO, the classification unit 10a determines whether or not the ratio of the image data in which the landscape is captured is larger than a predetermined ratio (step S6). When step S6 is branched to YES, the classification unit 10a determines that the event in which the image data is captured is “travel” (step S7). On the other hand, when step S6 is branched to NO, the classification unit 10a determines that the image data is “other” image data (step S8).

  When the processing in step S4, step S5, step S7, or step S8 is completed, the classification unit 10a stores music data suitable for the event in the storage unit 18 based on the event determined as described above. A selection is made from the stored music data (step S9).

  Note that the event determination process described with reference to FIG. 3 may be automatically performed at an appropriate timing after shooting, or may be executed according to a user instruction.

  Through the processing described above, based on the image data acquired by shooting, it is possible to determine the event in which the image data was shot and select and determine music data suitable for the event.

  FIG. 4 is a diagram illustrating a flowchart of processing by the camera control unit 10 relating to shooting control and playback control of the digital camera 1 according to the present embodiment.

  First, the camera control unit 10 determines whether or not the digital camera is set to a shooting mode (step S11). When step S11 is branched to YES, the camera control unit 10 determines whether a release operation has been performed by the user (step S12). When step S12 is branched to NO, the process returns to step S11. That is, step S12 is a step of waiting for a release operation performed by the user.

  On the other hand, when step S12 is branched to YES, the camera control unit 10 records the image data captured and acquired by the user's release operation in the storage unit 18 (step S13). Subsequently, the recording / reproducing unit 17 records the shooting time of the image data in the storage unit 18 in association with the image data (step S14). Further, the recording / reproducing unit 17 records the position of the face detected by the face detecting unit 22 in the storage unit 18 in association with the image data (step S15).

  Further, the camera control unit 10 determines whether there is image data (hereinafter referred to as immediately preceding image data) taken immediately before the image data (for example, within 10 minutes) (step S16). When this step S16 is branched to YES, the camera control unit 10 estimates that the image data is in the same image group as the previous image data, and the image data is “relevant to the previous image data”. The auxiliary information is incidentally recorded (step S17). This auxiliary information is used when classifying image data for slide show reproduction. On the other hand, when step S16 is branched to NO, the process returns to step S12.

  Thus, if there is auxiliary information indicating the relationship between the image data, grouping of the image data is facilitated when performing a slide show reproduction described later. At the time of slide show reproduction, since it is a single theme that the image data belonging to one classified group is to be reproduced rather than all the image data stored in the storage unit 18 is to be reproduced, the user Can be more entertaining.

  In addition, by making image data belonging to a certain group to be reproduced, for example, when reproducing a plurality of image data taken by a business colleague at the time of slide show reproduction, it suddenly relates to a user's private area. It is possible to prevent an unexpected situation that the image data is mixed and reproduced and the atmosphere of the place is broken.

  If the auxiliary information indicating the relation between the image data as described above is additionally recorded in the image data, the image data is reproduced and viewed immediately after shooting without performing the process of classifying into groups. It is also possible to use the camera as a communication tool, for example, to perform synthesis processing.

  After finishing the process in step S17, the camera control unit 10 further executes the event determination process described with reference to the flowchart shown in FIG. 3, and determines the music data to be played back during the slide show playback of the image data. The file name of the music data is recorded in the storage unit 18 (step S18). However, the process of step S18 is not automatically performed, but may be configured to be manually executed by the user before, for example, slide show reproduction.

  When the processing in step S18 is completed, it is determined whether or not an operation for turning off the power of the digital camera 1 has been performed (step S29). When step S29 is branched to NO, the process returns to step S11. On the other hand, when this step S29 is branched to YES, the power of the digital camera 1 is turned off and the process is terminated.

  When step S11 is branched to NO, the camera control unit 10 determines whether or not the digital camera 1 is set to the “music / image playback mode” by a user operation (step S19). When this step S18 is branched to NO, the camera control unit 10 sets the digital camera 1 to the “image playback mode” and plays back only the image without playing back the music data based on the operation by the user. Slide show reproduction is executed (step S30).

  Thereafter, it is determined whether or not a reproduction operation of predetermined music data has been performed by the user (step S31). When this step S31 is branched to NO, the processing in the “image reproduction mode” is continued as it is.

  On the other hand, when step S31 is branched to YES, the camera control unit 10 performs reproduction processing of music data and image data selected by the user (step S32).

  When step S19 is branched to YES, the camera control unit 10 has been subjected to event determination processing by image data belonging to the event determined by the event determination processing described with reference to the flowchart shown in FIG. Image data that is selected by the user is read out from the recording unit 18 as a reproduction candidate image for slide show reproduction (step S20). Subsequently, the switching instruction unit 10C determines whether or not the camera has been vibrated by the user (step S21).

  When step S21 is branched to YES, the camera control unit 10 determines the vibration frequency K and the vibration time tk of the vibration operation based on the output from the vibration detection unit 33 (step S22). Based on the determination result, the camera control unit 10 determines the display mode to be reproduced and displayed on the display unit 20 by the process shown in the flowchart of the subroutine shown in FIG. 5 (step S23).

  The display mode determination process will be described below with reference to the flowchart shown in FIG. For convenience of explanation, the number m of reproduction candidate images for slide show reproduction (the number of image data related to slide show reproduction) m is 4, and the image data is simply abbreviated as a, b, c, d in order of shooting date. Here, a and c are images whose face parts are main subjects (hereinafter referred to as face images). A group of image data such as a, b, c, and d is referred to as an image sequence.

  When there is no vibration operation on the camera (when the number of vibrations K = 0), the camera control unit 10 simply performs a → b → as shown in FIG. Slide show reproduction of image data is executed repeatedly in the order of c → d → a.

  First, let m be the number of reproduction candidate images for slide show reproduction (step S41). Subsequently, it is determined whether or not the vibration frequency K = 1 (step S42). When this step S42 is branched to YES, the reproduction order of the image data is randomly changed as shown in FIG. 6 (2) (step S45).

  An example of this random permutation is shown in FIG. In the example shown in FIG. 6 (2), for example, the reproduction order of c and a is changed, and the reproduction order is c → b → a → d → c. In step S45, the playback order may be switched at random, and this process can easily change the display mode of the slide show playback.

  When step S41 is branched to NO, it is determined whether or not the vibration time tk> 5 (sec) is satisfied (step S43). When this step S43 is branched to NO, among the reproduction candidate image data, the first image data and the next image data in the reproduction order are not subjected to the image processing in step S46 or step S47, which will be described later, and It is determined whether or not the image data has a portion as a main subject (step S44). When this step S44 is branched to NO, a “first one image processing mode (a mode in which a composition process is added to only the first image)” described later is performed (step S46).

  In the example shown in FIG. 6 (1), a is the image data of the face image, but b is not so, so step S44 is branched to NO.

  Hereinafter, the “first one image processing mode” subroutine in step S46 will be described with reference to the flowchart shown in FIG. That is, in the “first one image processing mode”, the camera control unit 10 first determines whether or not the vibration frequency K = 2 (step S61). When this step S61 is branched to YES, an enlargement process or a reduction process of the leading image a is executed to create an enlarged image or a reduced image (step S62). The image processing in step S62 is executed by the switching instruction unit 10c, the face detection unit 22, the cutout unit 23, and the synthesis processing unit 24 under the control of the camera control unit 10.

  Here, FIG. 6 (3) is a diagram showing a display example in the slide show reproduction of the image created in step S62. Here, in the display example, an image in which symbols (a to d) indicating each image are surrounded by a rectangle is an image subjected to image processing in step S46 or step S47. Yes. Therefore, images in which the symbols (a to d) indicating the respective images are not surrounded by rectangles in the display examples are images that have not been subjected to the image processing in step S46 or step S47. The images (a / 2, a / 3) synthesized for the slide show in this way are slide show secondary images.

  Note that the symbols indicating these images and the figures surrounding them are given for convenience of explanation, and are not displayed during actual slide show reproduction.

  In the example shown in FIG. 6 (3), a 1/2 reduced image (referred to as a / 2) of a that is the first image and a 1/3 reduced image (referred to as a / 3) are created and reduced. Images are sequentially displayed after a. That is, the slide show reproduction is repeatedly executed in the order of a → a / 2 → a / 3 → b → c → d → a → a / 2.

  Here, an example in which a reduced image is created and displayed has been shown here, but an enlarged image may be created and displayed in a similar manner. Further, it is assumed that the reduction magnification and the enlargement magnification can be arbitrarily set.

  By the way, when step S61 is branched to NO, it is determined whether or not the vibration frequency K = 3 (step S63). When this step S63 is branched to YES, a composite image (referred to as (a + a)) in which two face portions in the leading image a are arranged is created (step S64).

  FIG. 6 (4) is a diagram showing a display example of the composite image created in step S64. In the example shown in the figure, the second image in the reproduction order shows (a + a) that is the composite image created in step S64. When the slide show is reproduced, for example, as shown in FIG. 6 (4), the slide show is repeatedly performed in the order of a → (a + a) → b → c → d → a → (a + a).

  In step S64, for example, as shown in FIG. 6 (6), for example, it is possible to create a composite image (referred to as (a × 4)) in which four face portions in a which is the top image are arranged. There is no limit to the number of faces that can be arranged.

  On the other hand, when step S63 is branched to NO, an image (referred to as a ') in which color processing (for example, black-and-white reversal or sepia) is performed on a, which is the first image, is created as a composite image (step S65). .

  FIG. 6 (5) is a diagram showing a display example of the composite image created in step S65. In the example shown in the figure, the second image in the reproduction order shows a ′ that is the composite image created in step S65. When the slide show is reproduced, for example, as shown in FIG. 6 (4), the slide show is repeatedly reproduced in the order of a → a ′ → b → c → d → a → a ′.

  When the process in step S62, step S64, or step S65 ends, the process returns to the process of the flowchart shown in FIG.

  By the way, when step S44 in the flowchart shown in FIG. 5 is branched to YES, processing of “first two image processing mode (mode in which composition processing is added only to the first image and the next image)” is performed (step S47). .

  Hereinafter, the “first two image processing mode” subroutine in step S47 will be described with reference to the flowchart shown in FIG. That is, when step S44 is branched to YES, it is first determined whether or not the vibration frequency K> 3 is satisfied (step S71). When this step S71 is branched to NO, a composite image (referred to as (a × b)) is created by combining the face part in the first image a and the face part in the second image b (step a). S72). When the slide show is reproduced, the slide show is repeatedly performed in the order of a → (a × b) → b → c → d → a →.

  Note that the composition processing in step S72 is performed by, for example, using the face detection result to align the size of the face and using a morphing technique or the like. The morphing technique is a technique that makes a change in switching from one image to another appear to change naturally. It can be said that the composition process in step S72 is an effective composition when, for example, the first two images are both face images that have not been synthesized yet.

  On the other hand, when step S71 is branched to YES, two faces in the top image “a” are arranged in the upper stage, and two faces in the next image “b” are arranged in the lower stage. An image is created (step S73). Then, at the time of slide show reproduction, this composite four-divided image is inserted and reproduced and displayed, for example, between a and b.

  When the process in step S72 or step S73 is completed, the process returns to the process of the flowchart shown in FIG.

  By the way, when step S43 in the flowchart shown in FIG. 5 is branched to YES, that is, when the vibration time tk continues for a predetermined time or longer (here, 5 seconds or longer), the image processing performed in steps S45 to S47. Then, an “addition effect removal process” is performed (step S48).

  That is, in this step S48, all the composite images created based on the above-described vibration operation by the user and added to the original image sequence are removed from the original image sequence. By this step S48, all the composite images created up to that point based on the vibration operation of the digital camera by the user and inserted in the slide show reproduction are removed. This is an effective process when it is desired to eliminate a complicated image sequence or to recreate a new image sequence.

  When any one of steps S45 to S48 is completed, the camera control unit 10 calculates an image switching time tc during slide show reproduction (step S49).

In this step S49, the display switching time tc of the image is set to ts as the “reproduction time of the selected music” so that all the images in the image sequence are reproduced just in the time of music reproduction of one song, and m is set to m. “Number of playback candidate images”
tc = ts / m
Calculate with

  Subsequently, it is determined whether or not tc is 3 (sec) or more (step S50). When step S50 is branched to NO, tc is uniformly reset to tc = 3 (sec) (step S51).

  The process in step S51 is a process for making tc calculated in step S50 equal to or less than a predetermined value. This process takes into consideration that the image switching tempo as a slide show is deteriorated when the reproduction time of one piece of image data is too long.

  When step S50 is branched to YES, and after the processing in step S51 is completed, the process proceeds to step S24 in the flowchart shown in FIG.

  That is, the slide show control unit 10b temporarily stores the composite image created by the subroutine processing described with reference to FIG. 5 in the display temporary storage unit 18a in the storage unit 18 (step S24).

  Then, the slide show control unit 10b controls the music playback unit 34 and the like in the playback order described above to start playback of image data and music data (step S25). Further, the slide show control unit 10b determines whether or not the image display switching time tc has elapsed (step S26). When step S26 is branched to YES, the image data to be reproduced is switched to the next image data (step S27).

  When step S26 is branched to NO and after the processing in step S27 is completed, the slide show control unit 10b determines whether or not an operation for ending the slide show reproduction is performed by the user (step S28). . When step S28 is branched to NO, the process returns to step S21. On the other hand, when step S28 is branched to YES, the slide show reproduction is terminated.

  Note that the image synthesis process by the vibration operation is not limited to one process, and the above-described synthesis process can be combined by giving the digital camera the vibration operation in a plurality of times. Thereby, the number of images to be displayed can be further increased.

  Hereinafter, an example of processing when another type of vibration operation is performed after a predetermined vibration operation is performed by the user will be described with reference to FIGS.

(Vibration frequency K = 2 → Vibration frequency K = 3)
FIG. 9A is a diagram illustrating a display example of a slide show reproduction in the case where the vibration operation of the vibration frequency K = 2 is further performed after the vibration operation of the vibration frequency K = 2 is performed.

  As shown in the figure, in the state where the first vibration operation, that is, the vibration operation of the vibration frequency K = 2, is performed, the display is the same as the display example described with reference to FIG. Here, by further performing a vibration operation of the number of vibrations K = 3, as shown in FIG. 9A, three composite images ((a + a), (a + a) / 2, (a + a) / 3) Is added. Note that (a + a) / 2 is an image obtained by reducing (a + a) to ½, and (a + a) / 3 is an image obtained by reducing (a + a) to ３.

That is, as shown in FIG.
a → a / 2 → a / 3 → (a + a) → (a + a) / 2 → (a + a) / 3 → b → c → d → a → a / 2.
In this order, the slide show is repeatedly played back.

(Vibration frequency K = 2 → Vibration frequency K = 3 → Vibration frequency K = 4)
FIG. 9 (2) shows the slide show reproduction when the vibration operation of the vibration frequency K = 2 is performed after the vibration operation of the vibration frequency K = 2 is performed, and then the vibration operation of the vibration frequency K = 4 is further performed. It is a figure which shows the example of a display.

  That is, by the series of vibration operations, nine composite images ((a + a), (a + a) / 2, (a + a) /) are added to the display image when only the vibration operation of the vibration frequency K = 2 is performed. 3, a ′, a ′ / 2, a ′ / 3, a ′ + a ′, (a ′ + a ′) / 2, and (a ′ + a ′) / 3) are added.

That is, as shown in FIG.
a → a / 2 → a / 3 → a + a → (a + a) / 2 → (a + a) / 3 → a ′ → a ′ / 2 → a ′ / 3 → a ′ + a ′ → (a ′ + a ′) / 2 ...
In this order, the slide show is repeatedly played back.

(Vibration frequency K = 1 → Vibration frequency K = 3)
FIG. 9 (3) is a diagram showing a display example of a slide show reproduction in the case where the vibration operation with the vibration frequency K = 1 is further performed after the vibration operation with the vibration frequency K = 1 is performed.

As shown in the figure, in the state where the vibration operation of the first vibration frequency K = 1 is performed, the display is similar to the display example described with reference to FIG. Here, by further performing a vibration operation of the number of vibrations K = 3, a composite image ((c + c)) in which two face portions in c are arranged as shown in FIG. 9 (3) is added. That is, as shown in FIG.
c → (c + c) → b → a → d → c...
In this order, the slide show is repeatedly played back.

  Further, the control by the camera control unit 10 when a complex vibration operation is performed will be described with reference to FIGS. 10 (1) to 10 (4). It is assumed that the image sequence before the vibration operation is performed (the number of times of vibration K = 0) is a → b → c → d... As shown in FIG.

  First, in the above-described “first two-image processing mode”, when it is determined that the number of vibrations K> 3 is not satisfied (when step S71 is branched to NO), the face in the first image a and the second image A synthesized image ((a × b)) obtained by synthesizing the face portion at a certain b is created (step S72). When the slide show is reproduced, as shown in FIG. 10B, the slide show is repeatedly reproduced in the order of a → (a × b) → b → c → d → a →.

  Thereafter, when the user again performs a predetermined vibration operation (here, the vibration operation with the vibration frequency K = 2), the top a is an image that has not undergone image processing. Since the (a × b) th image is an image-processed image, the process branches to NO in step S44. That is, the “first one image processing mode” is applied.

  In this case, step S61 is branched to YES, and an enlarged / reduced image of the top image a is created (step S62). Here, it is assumed that reduced images of a / 2, (a × b) / 2, b / 2 are created.

  Through the processing described above, during slide show playback, as shown in FIG. 10 (3), a → a / 2 → (a × b) → (a × b) / 2 → b → b / 2 → c → Slide show playback is repeatedly performed in the order of d.

  For example, when the vibration operation of the vibration frequency K = 3, the vibration frequency K = 2, and the vibration frequency K = 1 is performed in this order, the reproduction order of the slide show reproduction described with reference to FIG. It is changed at random (see FIG. 10 (4)). In the case of this reproduction order, the two images (c and a) from the top are face images that have not been subjected to image processing. Therefore, in the next vibration operation, step S44 is branched to YES, and the above-described “first two image processing mode” processing is entered.

  As described above, according to the present embodiment, even when the number of images to be subjected to slide show playback is small, a playback device that can execute slide show playback rich in change with a simple operation, digital A camera, a slide show playback method, and a program can be provided.

  Specifically, various image processes such as an enlargement process, a reduction process, a division process, and a color change process are performed on an image related to a slide show reproduction by the user performing a vibration operation on the digital camera according to the present embodiment. An image that has been subjected to is automatically created.

  Therefore, even when there is only a small number of image data of the theme related to the slide show reproduction, according to the digital camera according to the present embodiment, for example, a variation is created from one theme. In addition, various variations of image display can be enjoyed.

  More specifically, in the digital camera according to the present embodiment, various image processing is performed on the images related to the slide show reproduction based on the vibration operation (the number of vibrations K and the vibration time tk) by the user. Increase the number of data. As a result, the number of images to be displayed within the reproduction time tm of the music data increases, so that the more the user shakes the digital camera, the faster slideshow reproduction is performed by switching images.

  According to the conventional technique, when the number of image data related to the slide show reproduction is small and when the image data is reproduced and displayed in accordance with the reproduction of the music data, the reproduction of the same image data is repeated every few seconds. Playback is displayed. That is, the slide show playback is very monotonous and easy to get tired for the viewer.

  However, according to the digital camera according to the present embodiment, even if there is a small amount of image data related to the slide show reproduction, an image subjected to various image processing (slide show secondary image) is displayed by the user. Since it is added as appropriate based on the vibration operation of the camera, it is possible to reproduce a slide show with elaborate contents. Accordingly, in order to increase the number of image data items related to reproduction during slide show reproduction, it is not necessary to forcibly include images that are lightly related to the image theme related to the slide show reproduction as reproduction candidates.

  Furthermore, in the digital camera according to the present embodiment, the user can perform the above-described various playback image switching by simply performing a simple operation of shaking the digital camera. This vibration operation is an intuitive operation that is in common with operations such as stirring the contents in the container or breaking an object by applying an impact, and is a very easy and natural operation for the user.

  As described above, according to the digital camera according to the present embodiment, it is possible to perform slide show reproduction in which interesting images are switched one after another with a wide variety of tempos regardless of the number of images related to the slide show reproduction.

  The embodiment of the present invention has been described above, but the present invention is not limited to this, and it is needless to say that various improvements and modifications can be made without departing from the spirit of the present invention.

For example, in the one embodiment, the vibration detection unit 23 is a member that simply determines the vibration operation applied to the digital camera. In addition, a 6-axis sensor or the like is used as the vibration detection unit 23. Of course, it may be possible to determine a more complicated stirring operation or throwing operation than the vibration operation. In such a configuration, the number of types of image composition processing can be increased.
As for each process performed by the camera control unit 10 described above, a part or all of the process may be configured by hardware. Of course, the processing by the face detection unit 22 and the like may be configured by software. Of course, the specific configuration is a matter of design.

  By the way, various control processes by the camera control unit 10 are realized as follows. That is, the software program stored in the ROM 13 is supplied to the camera control unit 10, and the camera control unit 10 causes each unit to execute the above-described operation according to the supplied program.

  That is, the software program itself realizes the function of the camera control unit 10. Therefore, the program itself is one embodiment of the present invention. Needless to say, a recording medium storing the program is also one embodiment of the present invention. As this recording medium, an optical recording medium such as a flash memory, a CD-ROM, a DVD-ROM, a magnetic recording medium such as an MD, a tape recording medium, and a semiconductor memory such as an IC card can be used.

  In the present embodiment, a digital camera has been described as an example. However, the present embodiment is not limited to a digital camera, and may be applied to, for example, a camera unit included in a mobile phone.

  Furthermore, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
