  The display unit 31 displays a live view through image, a mode setting screen, images in a slide show, and the like. As the display unit 31, a general liquid crystal monitor or the like can be appropriately selected and used.

  Next, the operation when displaying captured images in a slide show in the digital camera 1 according to the present embodiment will be described with reference to the flowcharts of FIGS.

  As described above, the user selects the slide show mode with the mode selection button of the operation unit 30 of the digital camera 1 and sets the image conditions (for example, the shooting mode and shooting date / time of a person or landscape) desired to be displayed in the slide show. specify. Then, the HVP of the control unit 14 creates the image unit list 50 according to the above-described procedure and stores it in the storage unit 15. And the process from step S10 is performed.

  Step S10: The control unit 14 reads the image unit list 50 stored in the storage unit 15, and stores all image data described in the image data file name area 52 of the image unit having the management number 1 in the storage unit. 15 is read. The control unit 14 changes the size of each image, performs rotation processing according to the display direction, and the like according to the instructions shown in the size area 53, the display direction area 54, and the display position area 55, and stores these images in the memory 11 Memorize temporarily.

  Step S20: The control unit 14 arranges each image with reference to the template 60 in FIG. 4 based on the plurality of image data prepared in Step S10, and outputs the output size of the external display device 100 (in this embodiment). For example, a display image in accordance with 1920 pixels × 1080 pixels) is generated. Here, the control unit 14 stores the display order shown in the display order area 56 of the image unit list 50 in a memory (not shown) or the like inside the control unit 14 and displays the display order on the external display device 100. Display each image in order.

  Step S30: The control unit 14 outputs the display image generated in step S20 to the display unit 31 so that the display unit 31 of the digital camera 1 displays the same display image as that displayed on the external display device 100. Perform resizing according to the size.

  Step S40: The control unit 14 displays the display image on the external display device 100 in accordance with the display order of the display order area 56, and displays the display image resized in step S30 on the display unit 31.

  Step S50: The control unit 14 determines whether or not there is an instruction for an enlargement display operation from the operation unit 30 when the user touches the screen of the display unit 31. When the control unit 14 determines that there is no enlarged display operation instruction from the user, the control unit 14 proceeds to step S120 (NO side). On the other hand, when there is an instruction for an enlargement display operation, the control unit 14 proceeds to step S60 (YES side).

  Step S60: The control unit 14 detects the coordinates at which the user touches the screen of the display unit 31, and displays the coordinates of the rectangular area of the image at the position of the coordinates, the number of the display position area 55, or the rectangular area. Find the corresponding image file name. In the present embodiment, the upper left of the screen of the display unit 31 is the origin (0, 0). Specifically, when the display area “0003.jpg” of the image having the management number “1” on the display unit 31 is touched by the user, the coordinates of the area or the display position area 55 is displayed. The display number or the file name “0003.jpg” is determined. The control unit 14 reads the determined image from the storage unit 15 and performs resizing, rotation processing, and the like for enlargement display.

  Step S70: The control unit 14 generates an enlarged display image in which the enlarged display image processed in step S60 is matched with the output size of the external display device 100.

  Step S80: The control unit 14 displays the enlarged display image generated in step S70 on the display unit 31 so that the display unit 31 of the digital camera 1 displays the same enlarged display image displayed on the external display device 100. Perform resizing processing according to the output size.

  Step S90: The control unit 14 displays the enlarged display image on the external display device 100, and displays the enlarged display image resized in step S80 on the display unit 31.

  Step S100: As shown in FIG. 2, the control unit 14 detects that the angular velocity sensor Y21 of the motion detection unit 13 is operated by the user rotating the digital camera 1 clockwise (positive rotation) or counterclockwise (negative rotation). It is determined whether the angular velocity to be detected is equal to or greater than the detection threshold value STh1 (positive value) or equal to or less than the detection threshold value STh2 (negative value) (FIG. 7). Here, FIG. 7 shows the time change of the angular velocity of the right rotation (positive rotation) detected by the angular velocity sensor Y21. FIG. 7A shows a case where the detected angular velocity has not reached the detection threshold value STh1, and FIG. 7B shows a case where the detected angular velocity is greater than or equal to the detection threshold value STh1.

  Therefore, the control unit 14 has detected no angular velocity by the angular velocity sensor Y21, or when the detected angular velocity is not equal to or greater than the detection threshold value STh1 or STh2 as shown in FIG. The process proceeds to step S110 (NO side). On the other hand, as shown in FIG. 7B, when the angular velocity detected by the angular velocity sensor Y21 is not less than the detection threshold value STh1 or not more than the detection threshold value STh2, the control unit 14 determines from the currently enlarged image, In order to perform the enlarged image forward / backward processing for enlarging the next image or the previous image set in the image data file name area 52 of the image unit, the process proceeds to step S60 (YES side), and steps S60 to S60 are performed. The process of step S90 is performed on the next image or the previous image.

  Specifically, for example, when the currently magnified image is “0003.jpg”, the control unit 14 controls the digital camera 1 to rotate right (positive rotation) from the angular velocity sensor Y21 to the right. When an angular velocity detection signal equal to or greater than the detection threshold value STh1 is received by rotation (positive rotation), the file name “0004.jpg” which is the next image in the image data file name area 52 of the image unit 1 is received. The control unit 14 proceeds to step S60 (NO side), performs enlarged image sending processing for enlarging and displaying “0004.jpg” in steps S60 to S90, and enlarging and displaying the image of “0004.jpg”. . On the other hand, when the control unit 14 receives a detection signal of an angular velocity equal to or lower than the detection threshold value STh2 by the left rotation (negative rotation) from the angular velocity sensor Y21 by the left rotation (negative rotation) operation of the digital camera 1 by the user, the image is displayed. The file name “0002.jpg” which is the previous image of the image data file name area 52 of the unit 1 is received. The control unit 14 performs an enlarged image return process for enlarging and displaying the image “0002.jpg” in the same procedure as in the above-described enlarged image feeding. Note that the detection threshold value STh1 and the threshold value STh2 in this embodiment are set to ± 180 (deg / sec), for example.

  Step S110: The control unit 14 determines whether or not an enlargement reproduction end instruction has been issued by the operation unit 30 when the user touches the screen of the display unit 31 that displays the enlarged image. If the control unit 14 determines that the user has not touched the screen of the display unit 31, the control unit 14 proceeds to step S <b> 100 (NO side), assuming that the operation unit 30 has not instructed the end of the enlarged reproduction. And the control part 14 performs the process of step S100 and step S110 until it receives some instruction | indication by a user via the display part 31 and the operation part 30. FIG. On the other hand, if the control unit 14 determines that the user has touched the screen of the display unit 31, the control unit 14 proceeds to step S <b> 120 (YES side), assuming that an instruction to end the enlarged reproduction is given by the operation unit 30, and normally Return to the slide show display of the image unit 1.

  Step S120: As in the case of step S100, the control unit 14 determines that the angular velocity detected by the angular velocity sensor Y21 by the user's operation of rotating the digital camera 1 to the right (positive rotation) or to the left (negative rotation) is It is determined whether or not the detection threshold value is STh1 (positive value) or more or STh2 (negative value) or less. If no angular velocity is detected by the angular velocity sensor Y21, or if the detected angular velocity is not greater than or equal to the detection threshold value STh1 or less than STh2 as shown in FIG. Move to (NO side). On the other hand, as shown in FIG. 7B, when the angular velocity detected by the angular velocity sensor Y21 is not less than the detection threshold value STh1 or not more than STh2, the control unit 14 proceeds to step S10 (YES side). Then, in step S10 to step S110, image unit sending for displaying a slide show of images from the current image unit 1 to the next image unit 2 or the previous image unit N (because there is no previous image unit of the image unit 1). / Return processing is performed.

  Step S130: The control unit 14 detects that the angular velocity detected by the angular velocity sensor X20 in the motion detection unit 13 by the user's operation of forward rotation (positive rotation) of the digital camera 1 is greater than or equal to the detection threshold value STh3 (positive value). It is determined whether or not there was. Note that the temporal change in the angular velocity of the forward rotation (positive rotation) detected by the angular velocity sensor X20 is the same as in the case of FIG. If no angular velocity is detected by the angular velocity sensor X20 or if the detected angular velocity is not equal to or greater than the detection threshold value STh3, the control unit 14 proceeds to step S150 (NO side). On the other hand, if the angular velocity detected by the angular velocity sensor X20 is equal to or greater than the detection threshold value STh3, the control unit 14 determines that a temporary stop instruction has been issued by the user, and proceeds to step S140 (YES side). Stop the slideshow temporarily.

  Step S140: The control unit 14 determines whether or not the instruction to resume the slide show has been performed again by the user in the forward rotation (positive rotation) operation of the digital camera 1. That is, when the angular velocity detected by the angular velocity sensor X20 is equal to or greater than the detection threshold value STh3 (positive value), the control unit 14 determines that the user has instructed to resume the slide show, and step S160 (YES side) Migrate to On the other hand, if the angular velocity detected by the angular velocity sensor X20 is not equal to or greater than the detection threshold value STh3 (positive value), the control unit 14 proceeds to step S140 (NO side) until the user issues a slideshow restart instruction. Stay.

  Step S150: The control unit 14 determines whether or not a slide show stop command has been issued by a user's operation of rotating the digital camera 1 backward (negative rotation). That is, when the control unit 14 detects no angular velocity by the angular velocity sensor X20 or the angular velocity detected by the angular velocity sensor X20 is not less than the detection threshold value STh4 (negative value), the control unit 14 Then, it is determined that there is no instruction to stop the slide show from the user, and the process proceeds to step S160 (NO side). On the other hand, when the angular velocity detected by the angular velocity sensor X20 is equal to or less than the detection threshold value STh4, the control unit 14 determines that a stop instruction has been given by the user, and ends the slide show.

  Step S160: The control unit 14 determines whether or not the display of all the images in the image unit has been completed. When it is determined that the display of all the images in the image unit is completed, the control unit 14 proceeds to step S170 (YES side). On the other hand, when it is determined that the display of all the images in the image unit is not completed, the control unit 14 proceeds to step S20 (NO side), performs the processing of step S20 to step S150, and performs the processing in the image unit. Displays all images of.

  Step S170: The control unit 14 determines whether or not slide reproduction has been completed for images of all image units. When it is determined that the slide reproduction of the images in all the image units has been completed (YES side), the control unit 14 ends the slide show. On the other hand, when it is determined that the slide reproduction of the images in all the image units has not been completed, the control unit 14 proceeds to step S10 (NO side), performs the processing of steps S10 to S160, and performs all the processing. The slide playback of the image of the image unit is performed and the process ends.

As described above, in this embodiment, by providing the two angular velocity sensors X20 and the angular velocity sensor Y21 as the motion detection unit 13 in the digital camera 1, an operation in a slide show of a plurality of captured images can be performed on the external display device 100, for example. While viewing (without looking at the display unit 31 of the digital camera 1), it can be performed interactively even while the slide is being reproduced, and the usability is improved.
≪Supplementary items for the embodiment≫
In the present embodiment, as the template 60, the template 60 shown in FIG. 4 is used, but the present invention is not limited to this. For example, not only the arrangement position of the image to be displayed, but also a template that can set a background image of the display image, a three-dimensional shadow or frame attached to each displayed image, audio data such as music, display time or display method, etc. It may be. Note that the display method does not simply display images in the display order shown in the display order area 56 of the image unit list 50 but refers to a display effect such as slide-in.

  As described above, instead of setting audio data such as music, display time, display method, etc. in the template 60, the unit number area 51, the image data file name area 52, the size area 53, In addition to the display direction area 54, the display position area 55, and the display order area 56, an area for setting audio data such as music, display time, display method, and the like is newly added to the image unit list 50 for each image. Also good.

  In this embodiment, in step S100, for example, when the currently enlarged image is “0003.jpg”, or in the case of enlarged image sending, the next in the image data file name area 52 of the image unit 1 is used. In the case of returning the enlarged image to “0004.jpg”, the previous image “0002.jpg” was enlarged and displayed, but the present invention is not limited to this. For example, the enlarged image feed / return is performed up to the first image “0001.jpg” or the last image “0005.jpg” set in the image unit 1, and an instruction for the next enlarged image feed / return operation is given by the user. In such a case, the control unit 14 may enlarge the image of the previous or next image unit (for example, “0005.jpg” of the image unit N, “0001.jpg” of the image unit 2, etc.). . The preceding and following images need not be performed in the order of the list of the image unit list 50, and may be determined according to the values of the display position area 55 and the display order area 56.

  In the present embodiment, the angular velocity associated with the rotational motion of the digital camera 1 is detected using the angular velocity sensor X20 and the angular velocity sensor Y21 as the motion detection unit 13, but the present invention is not limited to this. You may detect the angular acceleration of the digital camera 1 by two angular acceleration sensors.

  In the present embodiment, the digital camera 1 according to the present invention has been described as an example. However, the image stored in the storage unit 15 having an input unit for reading an image from outside without providing the imaging unit 10 is displayed as a slide show. It is also possible to configure as an image display device for display.

  In the present embodiment, the enlarged image advance / return operation in step S100, the image unit advance / return operation in step S120, the pause operation in step S130, the slide show restart operation in step S140, and the slide show stop operation in step S150 are motions. The angular velocity of right rotation (positive rotation) or left rotation (negative rotation) detected by the angular velocity sensor Y21 of the detection unit 13, or the forward rotation (positive rotation) or backward rotation (negative rotation) detected by the angular velocity sensor X20. However, the present invention is not limited to this, although it was performed based on the comparison between the angular velocity of each and the detection threshold value STh1 to the detection threshold value STh4.

  For example, after the user performs a right rotation (positive rotation) operation of the digital camera 1 in the enlarged image advance in step S100 or the image unit advance / return operation in step S120, the normal user moves the digital camera 1 back to the original. Perform left rotation (negative rotation) to return to posture. The waveform of the signal output from the angular velocity sensor Y21 at that time is as shown in FIG. Δt1 [ms] indicates a time interval until the user rotates the digital camera 1 clockwise (positive rotation) and then rotates counterclockwise (negative rotation). Then, if Δt1 is less than a predetermined time interval threshold value TTh1 (for example, 1 second), the control unit 14 ignores the downward signal indicating the left rotation (negative rotation). On the other hand, if Δt1 is equal to or greater than the threshold value TTh1, the control unit 14 performs the left rotation (negative rotation) by the user operation as an instruction for the enlarged image returning operation or the like in step S100. The same applies to a right rotation (positive rotation) after a left rotation (negative rotation).

  8B, as in FIG. 8A, the user rotates the digital camera 1 to the right (positive rotation) and then rotates to the left (negative rotation) below the threshold value TTh1, The waveform of the signal output by the angular velocity sensor Y21 in the case where the movement after the angular velocity of the left rotation (negative rotation) reaches the detection threshold value STh2 is slowly returned over time. If Δt2 is less than a predetermined time interval threshold value TTh2 (for example, 1 second), the control unit 14 ignores the signal indicating the left rotation (negative rotation). On the other hand, if Δt2 is equal to or greater than the threshold value TTh2, the control unit 14 performs the left rotation (negative rotation) by the user operation as an instruction for the enlarged image returning operation or the like in step S100. The same applies to a right rotation (positive rotation) after a left rotation (negative rotation).

  FIG. 9 shows signal waveforms output by the angular velocity sensor X20 and the angular velocity sensor Y21 when the user tilts the digital camera 1 in the upper right direction when performing the enlarged image feed operation in step S100, for example. As shown in FIG. 9, when the angular velocity detected by the angular velocity sensor Y21 exceeds the detection threshold value STh1 and the time when the angular velocity detected by the angular velocity sensor X20 exceeds the detection threshold value STh3 is different, depending on the magnitude of the time difference Δt3, The operation in the control unit 14 is different. That is, when the time difference Δt3 is less than a predetermined time difference threshold value TTh3 (for example, 0.5 second), the control unit 14 ignores the output signal of the angular velocity sensor X20 and rotates the digital camera 1 to the right (positive rotation) by the user. ) Perform processing corresponding to the operation only. On the other hand, when the time difference Δt3 is equal to or greater than the threshold value TTh3, the control unit 14 does not ignore a signal due to forward rotation (positive rotation) detected by the angular velocity sensor X20, and performs processing corresponding thereto. However, for the second operation, processing for the first operation is performed, and processing for operation detection after the transition of the slide show state is performed. Further, the user operation is detected using the same threshold value TTh3 in other combinations of user operations.
