  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a functional block diagram showing a schematic configuration of a digital camera according to the first embodiment of the present invention.

  In FIG. 1, the photographing unit 1 includes a photographing lens 2 having a zoom magnification function and an imaging element 3. An imaging light beam from a subject (not shown) is taken into the imaging device 3 via the imaging lens 2 and is photoelectrically converted. The photoelectrically converted output is processed as a digital image by the imaging unit 4.

  The imaging unit 4 is connected to a CPU 7, a DRAM 9, an image processing unit 10, a memory card 11, and an image display unit 12 via a bus 5.

  The CPU 7 controls the entire digital camera, and includes an image display control unit 7a that is a display control unit, a timer (not shown), and the like. The image display control unit 7a mainly executes an operation process of a flowchart described later. Although not shown, the CPU 7 is connected to an operation unit 8 having a switch corresponding to a selection button or an OK button, which will be described in detail later, in addition to a power switch, a release switch, and a zoom switch.

  The DRAM 9 is a memory for temporarily storing an image before image processing and an image during image processing. The image processing unit 10 is image processing means for performing various processes on an image to be displayed on the image display unit 12 and an image recorded on the memory card 11 or read from the memory card 11.

  The memory card 11 is for recording an image as a storage medium of the digital camera, and is configured to be detachable from the camera body.

  Further, the image display unit 12 functions as an image display unit, and displays the image processed by the image processing unit 10. The image display unit 12 is constituted by, for example, an LCD panel.

  FIG. 2 is an external perspective view of the digital camera according to the first embodiment viewed from the back side.

  In FIG. 2, a photographic lens 16 is attached to the front surface of the camera body 15. The upper surface of the camera body 15 has a release button 17 corresponding to the release switch, a zoom button 18 for zooming up and down corresponding to the zoom switch, a shooting frame, a shooting scene, etc. A display window 19 for displaying various information of the camera is provided.

  In addition, on the rear surface of the camera body 15, a finder window 20, a selection button 21 including four buttons 21 a to 21 d, and the image display unit 12 are displayed, and a photographed image and a subject image are displayed. There are provided a display panel (LCD panel) 22 and a plurality of operation buttons 23 for performing various setting operations at the time of photographing and image reproduction.

  The selection button 21 is provided as a key for moving a cursor (not shown) in the vertical and horizontal directions on the display window 19 and the LCD panel 22 in order to select information. Here, the upward selection button is called the upper button 21a, the left direction selection button is called the left button 21b, the right direction selection button is called the right button 21c, and the lower direction selection button is called the lower button 21d. In the present invention, the lower button 21d functions as a jump instruction means, a stop instruction means, and a display continuation instruction means.

  The details of the plurality of operation buttons 23 will be described later. For example, an OK button 23a for determining an operation by pressing the button, a “multi-image jump sending”, and a “continuous reproduction image jump sending” described later. A button for selecting a jump feed mode and a button corresponding to a frame number instruction means for specifying a frame number of an image to be reproduced are provided.

  Next, the operation of the digital camera configured as described above will be described.

  Here, only the operation of reproducing and displaying a pre-recorded image will be described, and description of other processing operations such as shooting will be omitted.

  FIG. 3 is a flowchart for explaining the image display operation of the digital camera.

  Now, when a certain image is read from the memory card 11, the image is displayed on the image display unit 12 (LCD panel 22) through the image processing unit 10 in step S1. In this state, the image displayed on the LCD panel 22 is switched depending on which of the selection buttons is pressed.

  In step S2, the state of the left button 21b is determined. If the left button 21b is pressed here, the process proceeds to step S3. In step S3, an image having a frame number one prior to the image currently displayed on the LCD panel 22 is displayed.

  On the other hand, when the left button 21b is not pressed in step S2, the process proceeds to step S4, and the state of the right button 21c is determined. As a result, if the right button 21c is pressed, the process proceeds to step S5, and an image having a frame number one after the image currently displayed on the LCD panel 22 is displayed.

  If the right button 21c is not pressed in step S4, the process proceeds to step S6 to determine the state of the lower button 21d. If the lower button 21d is pressed in step S6, the process proceeds to a jump feed process in which an image with a frame number in the middle is skipped and an image with a frame number ahead is displayed.

  In step S7, it is determined whether or not the image displayed during the jump is a multi-image display during the jump process. Here, the multi-image display means that a plurality of images are displayed on the LCD panel 22 at the same time. As a result, if it is a multi-image display, the process proceeds to step S8, and a “multi-image jump sending” process is performed. On the other hand, if it is determined in step S7 that the display is not multi-image display, the process proceeds to step S9, and the process of “continuous playback image jump sending” is performed.

  Next, the processing operation of the “multi-image jump sending” described above will be described with reference to the explanatory diagram of the screen of FIG. 4 and the flowchart of FIG.

  Assume that the first frame image is currently displayed on the LCD panel 22 as shown in FIG. When the lower button 21d is pressed, this routine is entered.

  In the embodiments described below, the numbers shown in the screens in the drawings represent frame numbers.

  In step S11, first, an intermediate frame image (from “2” to “2” in this case) between the frame number of the currently displayed image (in this case “1”) and the frame number of the jump destination image (in this case “11”). “10”) is converted into a multi-image by the image processing unit 10 and the like. For example, in this case, a multi-image in which the display image is divided into nine is created. The multi-image is created by the image processing unit 10, but the creation method is well-known, and a description thereof will be omitted.

  Next, in step S12, the created 9-divided multi-image is displayed on the LCD panel 22, as shown in FIG. The multi-image is displayed by a timer (not shown) in the CPU 7 until a predetermined time, for example, 1 second elapses in step S13.

  In step S14, as shown in FIG. 4C, the eleventh frame image, which is the frame number of the jump destination, is displayed on the LCD panel 22.

  As described above, according to the first embodiment, when searching for a desired image from a large number of images recorded on the memory card, it is possible to check the frame image on the way at a level that does not impair the search speed. Can be prevented, so that omission of search can be prevented. In the slide show type display that displays all the frames up to the jump destination frame sequentially, the display time per frame is remarkably shortened. Since it is natural to see only relevant frames without looking at them, search omissions can be prevented.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to an explanatory diagram of the screen in FIG. 6 and a flowchart in FIG.

  In the embodiment described below, except for the configuration of the digital camera and the processing operation of “multi-image jump sending”, it is the same as the above-described first embodiment, and therefore the same parts are the same. A reference number is attached and explanation is omitted.

  This second embodiment is also an example of the processing operation of “multi-image jump sending”, but the first embodiment described above only displays one multi-image when jumping halfway. On the other hand, in the second embodiment, a plurality of multi-images are displayed.

  Assume that the first frame image is currently displayed on the LCD panel 22 as shown in FIG. When the lower button 21d is pressed, this routine is entered. In step S21, first, an intermediate frame image (in this case, “2” to “2”) between the frame number of the currently displayed image (in this case “1”) and the frame number of the jump destination image (in this case “20”). Among the “19”), the multi-image (frame numbers “2” to “10”) of the first screen is created by the image processing unit 10 or the like. For example, in this case, multi-images from the second frame to the tenth frame in which the display image is divided into nine are created. Since this multi-image creation method is well known, a description thereof will be omitted.

  Next, in step S22, as shown in FIG. 6B, the created nine-division multi-image for the first screen is displayed on the LCD panel 22. For this multi-image, if the lower button 21d is pressed again during multi-image display in step S23, multi-image display is stopped and the process proceeds to step S27. If the lower button 21d is not pressed in step S23, a display is performed by a timer (not shown) in the CPU 7 until a predetermined time, for example, 1 second elapses in step S24.

  Further, in step S25, it is determined whether or not there are still multiple images up to the jump destination frame number. If there are still multiple images, it is determined that there is a next screen and the process proceeds to step S26. In this case, since the multiple images from the 11th frame to the 19th frame are present as the second screen as shown in FIG. 6C, after the number of screens is incremented in step S26, Control goes to step S21. Thereafter, the subsequent processing is repeated.

  If the next screen does not exist in step S25, the process proceeds to step S27, and as shown in FIG. 6D, the image of the 20th frame, which is the frame number of the jump destination, is displayed on the LCD panel 22. Is displayed.

  As described above, according to the second embodiment, a plurality of multi-images can be sequentially displayed, so that even when the number of frames in the middle of the jump is large, the image of the middle frame can be confirmed. .

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to the explanatory diagram of the screen in FIG. 8 and the flowchart in FIG.

  This third embodiment is also an example of the processing operation of “multi-image jump sending”, whereas the second embodiment described above displays a plurality of multi-images at the time of a jump in the middle, The multi-image being displayed is continuously displayed.

  Assume that the first frame image is currently displayed on the LCD panel 22, as shown in FIG. When the lower button 21d is pressed, this routine is entered. In step S31, first, an intermediate frame image (in this case, “2” to “2”) between the frame number of the currently displayed image (in this case “1”) and the frame number of the jump destination image (in this case “20”). Among the “19”), the multi-image (frame numbers “2” to “10”) of the first screen is created by the image processing unit 10 or the like. For example, in this case, multi-images from the second frame to the tenth frame in which the display image is divided into nine are created. Since this multi-image creation method is well known, a description thereof will be omitted.

  Next, in step S32, as shown in FIG. 8B, the created nine-divided multi-image of the first screen is displayed on the LCD panel 22. In step S33, it is determined whether or not the OK button 23a is operated during the display of the multi-image. Here, when the OK button 23a is not operated, the process proceeds to step S34, and it is determined by a timer (not shown) in the CPU 7 whether a predetermined time, for example, 1 second has elapsed. As a result, if the predetermined time has not elapsed, the process proceeds to step S32, and if it has elapsed, the process proceeds to step S35.

  In step S35, it is determined whether or not there are still multiple images up to the jump destination frame number. If there are still multiple images, the next screen is present and the process proceeds to step S36. In this case, multiple images from the 11th frame to the 19th frame exist as the second screen. Therefore, after the number of screens is incremented in step S36, the process proceeds to step S31. Thereafter, the processes of steps S31 to S35 are repeated.

  If the next screen does not exist in step S35, the process proceeds to step S37, and although not shown, the image of the 20th frame, which is the frame number of the jump destination, is displayed on the LCD panel 22.

  On the other hand, if the OK button 23a is pressed during the multi-image display as shown in FIG. 8B in step S33, the process proceeds to step S38, at the timing when the OK button 23a is pressed. The displayed multi-image is continuously displayed on the LCD panel 22 as shown in FIG. At this time, since the jump feeding operation is stopped, the next screen of the multi-image as shown by the broken line in FIG. 8C and the image of the jump destination frame are not displayed.

  When the multi-image display is stopped by pressing the OK button 23a, a selection frame is displayed on the specific image at that time, for example, the image of the center frame as shown in FIG. 8D. In the example shown in FIG. 8D, a selection frame is displayed on the sixth frame.

  Alternatively, only one frame image selected in the selection frame may be displayed.

  As described above, according to the third embodiment, it is possible to cope with a case where an image to be searched is found in the middle of jump display, or when it is desired to temporarily stop jump display.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described with reference to an explanatory diagram of the screen in FIG. 10 and a flowchart in FIG.

  The fourth embodiment is also an example of the processing operation of “multi-image jump sending”, whereas the first to third embodiments described above display the multi-image only by 9 divisions. The multi-image display is performed by changing the number of divisions.

  Assume that the first frame image is currently displayed on the LCD panel 22 as shown in FIG. When the lower button 21d is pressed, this routine is entered. In step S41, first, a multi-image divided into a predetermined number of the next screen of the frame number of the currently displayed image (in this case “1”), in this case, a multi-image of four divisions is created by the image processing unit 10 or the like. Is done. Since this multi-image creation method is well known, a description thereof will be omitted.

  Next, in step S42, as shown in FIG. 10B, the created four-part multi-image on the first screen is displayed on the LCD panel 22. In step S43, a timer (not shown) in the CPU 7 determines whether a predetermined time, for example, 1 second has elapsed. As a result, if the predetermined time has not elapsed, the process proceeds to step S42, and if it has elapsed, the process proceeds to step S44.

  In step S44, the multi-image divided into a number that is increased by one screen in both the vertical and horizontal directions from the multi-image of the first screen currently displayed, in this case, the multi-image of nine divisions is converted into the multi-image of the second screen. It is created by the processing unit 10 or the like.

  Next, in step S45, as shown in FIG. 10C, the created nine-segment multi-image of the second screen is displayed on the LCD panel 22. In step S46, a timer (not shown) in the CPU 7 determines whether a predetermined time, for example, 1 second has elapsed. As a result, if the predetermined time has not elapsed, the process proceeds to step S45, and if it has elapsed, the process proceeds to step S47.

  In step S47, it is determined whether or not a multi-image having the same number of divisions as the multi-image on the second screen still exists up to the jump destination frame number. If there are still multiple images, it is determined that there is a next screen and the process proceeds to step S48. In step S48, after the number of screens is incremented, the process proceeds to step S31. Thereafter, the processes of steps S44 to S47 are repeated.

  In step S47, if there is no multi-image having the same number of divisions as the current screen on the next screen, the process proceeds to step S49. Then, in this step S49, the multi-image divided into a number reduced by one screen in both the vertical and horizontal directions from the currently displayed multi-image, in this case, the multi-image of four divisions is converted into an image processing unit as a multi-image of the next screen. 10 etc.

  Next, in step S50, as shown in FIG. 10D, a four-part multi-image is displayed on the LCD panel 22. The multi-image is displayed on the LCD panel 22 until a predetermined time, for example, 1 second has elapsed by a timer (not shown) in the CPU 7 in step S51.

  Then, if 1 second has elapsed in step S51, the process proceeds to step S52, and as shown in FIG. 10E, the image of the eleventh frame which is the frame number of the jump destination is displayed on the LCD panel 22. Is displayed.

  As described above, according to the fourth embodiment, after the jump feed operation is started, for example, the display is performed from 1 frame to 4 frames, further 9 frames, and the number of divisions is increased or decreased step by step. The multi-image can be displayed in a shorter time than when switching from the frame image display to the multi-image divided into a large number.

  Further, since the number of divisions is changed step by step, the size per image is also changed stepwise, which is easy for the user to see.

  Furthermore, in the above-described fourth embodiment, the multi-image is described as being divided into four and nine, but the multi-image may be configured with other division numbers.

  Note that the four-segment multi-image shown in FIGS. 10B and 10D displays four adjacent frames of the nine-segment multi-image shown in FIG. 10C. It is not limited to. For example, it is a matter of course that four consecutive frames may be displayed.

(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described with reference to an explanatory diagram of the screen in FIG. 12 and a flowchart in FIG.

  The fifth embodiment is also an example of the processing operation of “multi-image jump sending”. In addition to the fourth embodiment described above, the multi-image after the start of the jump sending operation is not displayed. It is.

  As shown in FIG. 12A, the first frame image is displayed on the LCD panel 22, and this routine is entered when the lower button 21d is pressed. Then, in steps S61 and S62, as in steps S41 and S42 in the flowchart of FIG. 11 described above, the multi-image on the next screen of the frame number of the currently displayed image (in this case, “1”), in this case A four-divided multi-image is created by the image processing unit 10 or the like and displayed on the LCD panel 22 as shown in FIG.

  In step S63, the state of the lower button 21d is determined in a state where the four-divided multi-image is displayed. If the lower button 21d is pressed here, the process proceeds to step S75 described later. On the other hand, when the lower button 21d is not operated, the process proceeds to step S64.

  In step S64, it is determined by a timer (not shown) in the CPU 7 whether a predetermined time, for example, 1 second has elapsed. As a result, if the predetermined time has not elapsed, the process proceeds to step S62, and if it has elapsed, the process proceeds to step S65.

  In step S65, the multi-image divided into a number that is increased by one screen in both the vertical and horizontal directions from the multi-image on the first screen that is currently displayed, in this case, the multi-image of nine divisions is used as the multi-image on the second screen It is created by the processing unit 10 or the like.

  Next, in step S66, the nine-divided multi-image on the second screen is displayed on the LCD panel 22. Further, in step S67, the state of the lower button 21d is determined in a state where the 9-divided multi-image is displayed. If the lower button 21d is pressed, the process proceeds to step S75 described later. If the lower button 21d is not operated, the process proceeds to step S68.

  In step S68, a timer (not shown) in the CPU 7 determines whether or not a predetermined time, for example, 1 second has elapsed. As a result, if the predetermined time has not elapsed, the process proceeds to step S66, and if it has elapsed, the process proceeds to step S69.

  Subsequent steps S69 to S72 are the same as steps S47 to S50 in the flowchart of FIG.

  In step S73, the state of the lower button 21d is determined in a state where the four-divided multi-image is displayed. If the lower button 21d is pressed, the process proceeds to step S75 described later. If the lower button 21d is not operated, the process proceeds to step S74.

  In step S74, it is determined by a timer (not shown) in the CPU 7 whether a predetermined time, for example, 1 second has elapsed. As a result, if the predetermined time has not elapsed, the process proceeds to step S72, and if it has elapsed, the process proceeds to step S75. In step S75, as shown in FIG. 12E, the eleventh frame image, which is the frame number of the jump destination, is displayed on the LCD panel 22.

  By the way, when the lower button 21d is pressed in steps S63, S67, and S73 described above, the process proceeds to step S75. For example, when the lower button 21d is pressed in step S63, the four-divided multi-image display displayed at that time disappears. Thereafter, the 9-divided multi-image and the 4-divided multi-image as shown in FIGS. 12C and 12D are not displayed, and the process proceeds to step S75, as shown in FIG. The eleventh frame image, which is the frame number of the jump destination, is displayed on the LCD panel 22.

  As described above, according to the fifth embodiment, it is possible to cope with a case where an image to be searched is found in the middle of display after a jump feed operation is started or a case where it is desired to temporarily interrupt the display.

(Sixth embodiment)
Next, a sixth embodiment of the present invention will be described.

  FIG. 14 is an explanatory diagram of a “continuous reproduction image jump sending” screen according to the sixth embodiment of the present invention, and FIG. 15 is a “continuous reproduction image jump sending” according to the sixth embodiment. It is a flowchart explaining operation | movement of.

  In the embodiment described below, except for the configuration of the digital camera and the processing operation of “continuous playback image jump sending”, it is the same as the first embodiment described above, and therefore the same parts are the same. The reference number is attached and description is abbreviate | omitted.

  If it is determined in step S7 that the display is not multi-image display according to the flowchart of FIG. 3, the routine of “continuous reproduction image jump sending” in step S9 is entered.

  As shown in FIG. 6A, when the lower button 21d is pressed while the first frame image is currently displayed on the LCD panel 22, this routine is entered. In step S81, the frame number of the currently displayed image (in this case, “1”) is incremented, the frame number of the continuously reproduced image is initialized, and the frame number of the image incremented in the subsequent step S82 ( In this case, the display image “2”) is created by the image processing unit 10 or the like.

In step S83, the display time of the created image is set by a timer (not shown) in the CPU. Here, the set time of the timer is set so that the display time is gradually shortened from a long time and gradually becomes longer as the jump destination image is approached. For example, it is a display time table of variable speed display shown in Table 1 below. The table is stored in the CPU or in an external memory (not shown).

  According to this, the frames during the jump display, in this case, the second and third frames are 0.3 seconds, then the fourth and fifth frames are 0.2 seconds, and the sixth and seventh frames are 0. .1 second, 8th frame is displayed for 0.2 second, 9th frame and 10th frame are displayed for 0.3 second.

  In step S84, the frame image created in step S82 is displayed on the LCD panel 22. In step S85, it is determined whether or not the predetermined time set in step S83 has elapsed. Thereby, the display time corresponding to the frame number is determined.

  Next, in step S86, it is determined whether or not the last frame number of continuous reproduction has been reached. In this case, if the 10th frame has not been reached, the process proceeds to step S87 where the frame number is incremented. Thereafter, the process proceeds to step S82, and the processes of steps S82 to S86 are repeated. As a result, as shown in FIG. 14B, the image being jumped is displayed with a time change.

  On the other hand, if the last frame number (in this case, “10”) of the continuous reproduction has been reached in step S86, the process proceeds to step S88. In step S88, as shown in FIG. 14C, the image of the jump destination frame number is displayed on the LCD 22.

  Thus, according to the sixth embodiment, instead of simply continuously displaying up to the jump destination frame, the display time of the image on the way is changed so as to emphasize the feeling of movement and the feeling of jumping. Since it is attached, it becomes easy for the user to search for an image at the time of searching, and the middle can be displayed at high speed.

(Seventh embodiment)
Next, a seventh embodiment of the present invention will be described.

  In the sixth embodiment described above, the display time of the image being jumped is displayed with a step change in time, whereas in this seventh embodiment, the actual shooting time interval is displayed. It is made to display according to the ratio.

  The processing operation of “continuous playback image jump sending” is the same as that in the flowchart in the sixth embodiment shown in FIG. 15, and only the timer set time in step S83 is different.

That is, the set time of the timer is as shown in Table 2 below, and will be described with reference to FIG.

Since the shooting time data is attached to each image data and recorded in the memory card 11, the CPU 7 reads the data, calculates the time difference, and performs the following processing.

  Now, as shown in FIG. 16A, after the image of the first frame is displayed, the image of the second frame is displayed on the LCD panel 22 as an image being jumped. The photographing time difference Δt1 between the second frame and the third frame is 1 hour or more from Table 2 above, and is displayed for 0.6 seconds. Furthermore, since the shooting time difference Δt2 between the third frame and the fourth frame and the shooting time difference Δt3 between the fourth frame and the fifth frame are less than one hour, both are displayed for 0.3 seconds. Similarly, the display time up to the 10th frame is obtained. Then, as shown in FIG. 16 (b), the display time is different between the frame having the short shooting time interval and the shooting time.

  Then, the image of the jump destination frame number (“11”) is displayed on the LCD 22 as shown in FIG.

  As described above, according to the seventh embodiment, each frame is not displayed at equal time, but is displayed with the strength and weakness according to the shooting date and time.

(Eighth embodiment)
Next, an eighth embodiment of the present invention will be described with reference to an explanatory diagram of the screen in FIG. 17 and a flowchart in FIG.

  The eighth embodiment is an example of the processing operation of “continuous reproduction image jump sending”, in which an image in the middle of jump display is hidden.

  As shown in FIG. 17A, the first frame image is displayed on the LCD panel 22, and this routine is entered when the lower button 21d is pressed. In step S91, the frame number of the currently displayed image (in this case, “1”) is incremented, and in the subsequent step S92, the frame image number (in this case, “2”) incremented is displayed. Created by the image processing unit 10 or the like. In step S93, the created image is displayed on the LCD panel 22.

  Here, in step S94, the state of the lower button 21d is determined. If the lower button 21d is pressed here, the process proceeds to step S99 described later. On the other hand, when the lower button 21d is not operated, the process proceeds to step S95.

  In step S95, it is determined whether or not a predetermined time set in advance by a timer (not shown) in the CPU 7, for example, 1 second has elapsed. As a result, if the predetermined time has not elapsed, the process proceeds to step S93, and if it has elapsed, the process proceeds to step S96.

  In step S96, it is determined whether or not the last frame number of continuous playback has been reached. In this case, if the 10th frame has not been reached, the process proceeds to step S97 and the frame number is incremented. Thereafter, the process proceeds to step S92, and the processes of steps S92 to S96 are repeated.

  On the other hand, if the last frame number (in this case, “10”) of continuous playback has been reached in step S96, the process proceeds to step S98. In step S98, as shown in FIG. 18C, the image of the jump destination frame number is displayed on the LCD 22.

  By the way, when the lower button 21d is pressed in step S94, the image being jumped in step S99 is not displayed. For example, as indicated by a broken line in FIG. 17B, the images from the sixth frame to the tenth frame are not displayed. Then, the process proceeds to step S98, and an image of the jump destination frame number is displayed.

  As described above, according to the eighth embodiment, it is possible to allow an instruction to move to a jump destination frame at once, and to improve usability.

(Ninth embodiment)
Next, a ninth embodiment of the present invention will be described with reference to an explanatory diagram of the screen in FIG. 19 and a flowchart in FIG.

  The ninth embodiment is an example of the processing operation of “continuous reproduction image jump sending”, and it is possible to continuously display an image being displayed.

  As shown in FIG. 19A, the first frame image is displayed on the LCD panel 22, and this routine is entered when the lower button 21d is pressed. Steps S101 to S103 are the same as steps S91 to S93 in the flowchart of FIG.

  In step S104, it is determined whether or not the OK button 23a has been operated while an intermediate image is being displayed. Here, when the OK button 23a is not operated, the process proceeds to step S105, and it is determined whether or not a predetermined time, for example, 1 second has elapsed by a timer (not shown) in the CPU 7. As a result, if the predetermined time has not elapsed, the process proceeds to step S103, and if it has elapsed, the process proceeds to step S106.

  In step S106, it is determined whether or not the last frame number of continuous playback has been reached. In this case, if the 10th frame has not been reached, the process proceeds to step S107 and the frame number is incremented. Thereafter, the process proceeds to step S102, and the processes of steps S102 to S106 are repeated.

  On the other hand, if the last frame number of continuous playback (in this case “10”) has been reached in step S106, the process proceeds to step S108. In step S108, an image of the jump destination frame number is displayed on the LCD 22.

  In step S104, if the OK button 23a is pressed while an intermediate image is displayed as shown in FIG. 19B, the process proceeds to step S109 and is displayed at the timing when the OK button 23a is pressed. The intermediate image that has been displayed is displayed on the LCD panel 22 as shown in FIG. At this time, since the jump feed operation is stopped, an intermediate image as shown by a broken line in FIG. 19B is not displayed.

  As described above, according to the ninth embodiment, it is possible to cope with a case where an image to be searched is found on the way or a case where it is desired to interrupt the search.

(Tenth embodiment)
Next, a tenth embodiment of the present invention will be described with reference to an explanatory diagram of the screen in FIG. 21 and a flowchart in FIG.

  The tenth embodiment is an example of the processing operation of “continuous reproduction image jump sending”, and only an image having a specific frame number is displayed among images being displayed.

  As shown in FIG. 21A, the first frame image is displayed on the LCD panel 22, and this routine is entered when the lower button 21d is pressed. In step S111, a predetermined number of frames is added to the frame number of the currently displayed image (in this case, “1”). The number of frames can be changed as appropriate. Here, the number of frames is incremented by “2” to display an intermediate image every other frame.

  Next, a display image of the frame number of the image incremented in step S112 (in this case “3”) is created by the image processing unit 10 or the like. In step S113, the created image is displayed on the LCD panel 22.

  In step S114, it is determined whether or not a predetermined time, for example, 1 second has elapsed by a timer (not shown) in the CPU 7. As a result, if the predetermined time has not elapsed, the process proceeds to step S113, and if it has elapsed, the process proceeds to step S115.

  In step S115, it is determined whether or not the last frame number of continuous reproduction has been reached. In this case, if the ninth frame has not been reached, the process proceeds to step S116, and the frame number is incremented by the same number (in this case, 2) as in step S111. Thereafter, the process proceeds to step S112, and the processes of steps S112 to S115 are repeated.

  On the other hand, if the last frame number (in this case “9”) of the continuous reproduction has been reached in step S115, the process proceeds to step S117. In step S117, an image of the jump destination frame number is displayed on the LCD 22, as shown in FIG.

  In this way, as shown in FIG. 21B, it is possible to display a predetermined number of images, for example, every other frame, during the jump.

  As described above, according to the tenth embodiment, the time for jump display can be shortened.

  In the above-described embodiment, the digital camera has been described. However, the present invention is not limited to this. Of course, as long as the image can be reproduced and displayed from the recording medium, the present invention can be applied to a camera unit of a mobile phone and a PDA image display device other than the camera.
