As a result, it is possible to determine whether or not the video is desired to be played back before starting to play back the moving image, thereby preventing unnecessary video playback.

  Preferred embodiments of an image reproducing device, an image reproducing method, an image recording / reproducing method, and a digital camera according to the present invention will be described below in detail with reference to the accompanying drawings.

  1 and 2 are a front view and a rear view, respectively, showing the appearance of the digital camera according to the present invention.

  As shown in these drawings, this camera is a digital camera 1 capable of recording / reproducing moving images / still images. On the front side of the camera is a photographing lens 10, a finder window 12, and auxiliary light emission as shown in FIG. A portion 14 is provided. As the auxiliary light emitting unit 14, a strobe device is used in the case of a camera dedicated to still images, and a white light emitting diode or lamp is used in the case of a camera that is also used as a moving image still image.

  On the other hand, on the rear side of the camera, as shown in FIG. 2, a display panel 20 for displaying recording (time), date, remaining memory, viewfinder eyepiece 22, zoom button 24, menu key 26, execution key 28, A multifunction cross key 30, a cancel key 32, an image monitor 34, and a speaker 36 are provided.

  As shown in FIGS. 1 and 2, a power switch / mode switch 40 and a shutter button / recording start / end button 42 are provided on the upper surface of the camera, and an earphone jack is provided on the right side of the camera in FIG. 44 and a recording medium insertion section 46 are provided.

  The power switch / mode switch 40 has four positions: a neutral position in which the power is turned off, a position in which the power is turned on and in the still image shooting mode, a position in which the power is turned on and in the moving image shooting mode, and a power on and playback mode. Switch. Instead of the power switch / mode change switch 40, the power ON / OFF switch may be used, and the still image shooting mode, the moving image shooting mode, and the playback mode may be switched using another mode dial or the like.

  FIG. 3 is a block diagram showing an internal configuration of the digital camera 1 shown in FIGS. The digital camera 1 includes a photographing lens 10, an auxiliary light emitting unit 14, an image monitor 34, a multifunction cross key 30, an operation switch group 41 such as a power switch / mode change switch 40, a shutter button / recording start / end button 42, Shutter / aperture 50, imaging device 52 such as CCD, analog signal processing circuit 54, A / D converter 56, digital signal processing circuit 58, memory 60, compression / decompression circuit 62, built-in memory or memory card 64, drive circuit 66, And a CPU (central processing unit) 68 and the like.

  The CPU 68 comprehensively controls each circuit of the entire camera based on input signals from the operation switch group 41, the shutter button / recording start / end button 42, and the like. Now, when the power is turned on by the power switch / mode switch and the still image shooting mode or the moving image shooting mode is set, the still image or moving image is shot based on the operation of the shutter button / recording start / end button. When the playback mode is set, a still image or a moving image is played back.

  Now, the light passing through the photographing lens 10 and the shutter / aperture 50 in the still image photographing mode or the moving image photographing mode is focused on the imaging device 52. Here, the shutter prevents light from entering the imaging device 52 and generating smear when reading a signal from the imaging device, but is not necessarily required depending on the configuration of the imaging device 52. In addition, the diaphragm can be a single diaphragm or a plurality of diaphragms that can be switched. The auxiliary light emitting unit 14 emits auxiliary light at low illuminance or forcibly to illuminate the subject. The auxiliary light emitting unit 14 may be auxiliary light other than the strobe light, or may be omitted if the sensitivity of the imaging device is high.

  The imaging device 52 is driven at a timing generated by a timing generation circuit (not shown) in the driving circuit 66 and outputs an image signal. The drive circuit 66 also includes drive circuits such as the photographing lens 10, the shutter / aperture 50, and the auxiliary light emitting unit 14.

  The image signal output from the imaging device 52 is subjected to analog signal processing by the analog signal processing circuit 54, then converted to a digital signal by the A / D converter 56, and added to the digital signal processing circuit 58, where digital processing is performed. Is given. The digitally processed image data is temporarily recorded in the memory 60. Here, by reading out the image data in the memory 60 and outputting it to the image monitor 34, a moving image or a still image can be displayed on the image monitor 34. The image data after photographing is compressed by the compression / decompression circuit 62 and recorded in the built-in memory or the memory card 64. Depending on the shooting mode, recording may be performed without the compression process. In the reproduction mode, the image data recorded in the built-in memory or the memory card 64 is decompressed by the compression / decompression circuit 62 and then output to the image monitor 34 via the memory 60, and the reproduced image is displayed on the image monitor 34. It has come to be.

  In the digital camera 1 configured as described above, when the still image shooting mode is selected and the shutter button / recording start / end button 42 is pressed, an image for one frame is shot, and a file name is assigned to the image (still image). And recorded in the built-in memory or memory card 64. On the other hand, when the moving image shooting mode is selected and the shutter button / recording start / end button 42 is pressed, images are continuously shot at a predetermined frame rate until the shutter button / recording start / end button 42 is pressed again. The file name is attached to the continuous image (moving image) and recorded in the built-in memory or the memory card 64.

  Note that the file in which the still image is recorded and the file in which the moving image is recorded are stored in the holder in the shooting order regardless of the still image or the moving image. In the moving image shooting mode, sound can be recorded simultaneously by a sound recording means (not shown), and in a playback mode described later, it can be reproduced as a moving image with sound.

  Next, a case where a still image or a moving image recorded in the built-in memory or the memory card 64 is reproduced will be described.

  For image playback in the playback mode, one frame playback, index playback for playing back an index image consisting of a plurality of frames (4 frames in this embodiment), and one frame of a movie during single-frame playback or index playback are displayed. In this state, there is a moving image reproduction performed when an instruction to reproduce a moving image is given. Note that one frame of the moving image displayed at the time of frame advancement or index reproduction during single frame playback may be the first frame of the moving image or one frame positioned about ½ of the entire length of the moving image.

  When the playback mode is selected, one-frame playback is automatically performed, and one frame of the first file is selected and played back on the image monitor 34. Note that one frame of the last file may be reproduced on the image monitor 34. Here, when performing one-frame playback of another frame, the frame is advanced by the left / right key of the multifunction cross key 30. As a result, the playback images are sequentially advanced.

  When index reproduction is instructed, an index image consisting of four frames is displayed. On the index image, the frame to be reproduced can be selected with the up / down key and the left / right key of the cross key 30. The selected frame is trimmed and distinguished from other frames. When the up / down key and the left / right key of the cross key 30 are operated beyond the range of the index image, the index screen is switched.

  As described above, the file in which the still image is recorded and the file in which the moving image is recorded are mixed and stored in the built-in memory or the memory card 64 in accordance with the shooting order. A single frame of a picture or video is displayed in a mixed manner. Similarly, in index reproduction, there are cases where a still image and a single frame of a moving image are mixedly displayed in the index image.

  In view of this, the display form of both images is changed so that a still image and a moving image frame can be intuitively distinguished during single frame reproduction or index reproduction.

  FIGS. 4 to 6 are diagrams showing index images displayed by changing display forms of still images and moving images during index reproduction.

  In the embodiment shown in FIG. 4, the still image 70 in the index image is displayed as an image with a white frame so as to be reminiscent of a photograph, while the one-frame image 72 of the movie is a movie film. As if reminiscent, it is displayed as an image in which perforations 72A are combined at the left and right ends of one frame. This makes it possible to intuitively recognize whether each frame in the index image is a still image or one frame of a moving image.

  In the embodiment shown in FIG. 5, the still image 70 in the index image is displayed as an image with a white frame as in the case of FIG. 4, while the image 74 showing the moving image has a motion. In this way, several frames constituting a moving image are repeatedly played. Note that the number of frames constituting the moving image is not limited to a continuous frame of the moving image, and may be a relatively long frame in order to emphasize the motion.

  In the embodiment shown in FIG. 6, the still image 76 and the single frame image 78 in the index image are displayed as images without white frames, but the single frame image 78 of the moving image is It is displayed to vibrate vertically. Since this vibration may give the impression of being broken if it is randomly vibrated, it can be vibrated finely or sometimes vertically, as when playing an old film such as 8 mm. You may make it give atmosphere to movement. By vibrating the screen in this way, it can be recognized that it is one frame of a moving image.

  The perforation 72A synthesized with the single frame image 72 of FIG. 4 may be combined with the single image 74 showing the moving image of FIG. 5 or the single frame image 78 of FIG. In some cases, the perforation may move vertically.

  FIGS. 4 to 6 show the display form of still images and moving images on the index images, respectively. However, as described above, still images and moving images can be recognized even during single-frame playback. And the video are displayed in different display forms.

  Further, at the time of one-frame playback, one frame may be displayed as a still image, and a moving image may be displayed as a four-screen multi-image as shown in FIG. According to this, when one frame is displayed during frame-by-frame playback, a still image can be recognized as a moving image (four frames in a moving image) when a four-screen multi-image is displayed. .

  Next, the case of a 4-screen multi-image showing a moving image will be described.

  As shown in FIG. 7, this four-screen multi-image is composed of the first frame image 80A, the middle frame images 80B and 80C, and the last frame image 80D of all the frames constituting the moving image. Has been.

  For example, if the moving image is composed of 400 frames, each frame is divided into 4 frames, each divided into 1 to 100 frames, 101 to 200 frames, 201 to 300 frames, and 301 to 400 frames. A 4-screen multi-image is constructed from the selected 4 frames.

  Thus, by displaying the 4-screen multi-image related to the moving image like a four-frame cartoon, the contents of the entire moving image can be grasped before the moving image is reproduced.

  In this embodiment, the four-screen multi-image has been described. However, the number of frames constituting the multi-screen is not limited to four, and for example, a nine-screen multi-image may be used. In this case, the nine-screen multi-image is formed by dividing all the frames constituting the moving image into nine equal parts, and taking out one frame from each of the nine divided frame groups.

  In addition, when a frame is framed or wiped during movie shooting, the first frame has no meaning, and the last frame may also have no meaning. A multi-image may be composed of frames obtained by removing the first plurality of frames and the last plurality of frames from the frames. The multi-image may be created in advance and recorded in association with the moving image file.

  Further, in this embodiment, a multi-image is configured based on a plurality of frames that are appropriately extracted from all frames of the moving image, and the multi-image is displayed. Repeated frame advance display may be used. In particular, since one frame at the time of index reproduction is small, it is preferable to sequentially display a plurality of frames within one frame rather than displaying them on a multi-screen.

  Next, the procedure for reproducing images of still images and moving images will be described with reference to the flowchart shown in FIG.

  As shown in FIG. 8, when the playback mode is selected and the playback mode is started (step S10), as described above, one-frame playback is automatically performed, and the first file in the built-in memory or the memory card 64 (first Are selected (step S12).

  Whether the selected file is a still image file or a moving image file is automatically determined (step S14). If the selected file is a still image file, the still image is displayed on the image monitor 34 based on the image data of the file (step S14). Step S16). Thereafter, the operation of the left / right key of the multifunction cross key 30 selects whether to display the next frame or the previous frame (step S18). When the right key of the cross key 30 is operated, the next file (next frame) is selected (step S20), and then the process returns to step S14. When the left key of the cross key 30 is operated, the previous file is selected. Is selected (step S22), the process returns to step S14.

  On the other hand, if the selected file is a moving image file, a part of the moving image is reproduced based on the image data of the file (step S24). By partial playback of this moving image, perforation is synthesized and displayed on one frame of the moving image (see image 72 in FIG. 4), or several frames constituting the moving image are repeatedly displayed (see image 74 in FIG. 5), or One frame of the moving image is displayed so as to vibrate vertically (see image 78 in FIG. 6), or four frames in the moving image are displayed as a 4-screen multi-image (see FIG. 7).

  Based on the partial playback of the video in step S24, the user selects whether to perform video playback for playing back all the frames of the partially played video, or to perform frame advance without video playback (step S26). . When an instruction to select moving image playback is given, the moving image is continuously reproduced from the beginning to the end based on the image data of the selected moving image file (step S28). Thereafter, in step S30, it is selected whether to perform moving image reproduction again or frame-by-frame.

  In step S26 or step S30, when the right key of the cross key 30 is operated, after the next frame is selected (step S20), the process returns to step S14, and when the left key of the cross key 30 is operated, Is selected (step S22), the process returns to step S14.

  In addition, after the partial reproduction of the moving image in step S24, the moving image is reproduced only when the instruction for reproducing the moving image is input, so that only the moving image desired to be reproduced can be selectively reproduced. Because. In addition, once the video playback is started, the load on the CPU increases, and it is impossible to quickly reflect the switch instruction to stop the video playback, and there is a problem that frame advancement cannot be performed until the video playback ends. Because.

  Next, a procedure for reproducing images of still images and moving images will be described with reference to the flowchart shown in FIG. In addition, the same step number is attached | subjected to the part which is common in the flowchart shown in FIG. 8, The detailed description is abbreviate | omitted.

  The flowchart shown in FIG. 9 is different in that steps S40, S42, and S44 are provided instead of step S28 in the flowchart of FIG.

  The digital camera 1 shown in FIG. 1 and the like is recorded in a built-in memory or a memory card 64 as a moving image with sound during moving image shooting. In steps S40, S42, and S44 in FIG. 9, when reproducing a moving image with sound recorded in the built-in memory or the memory card 64, it is possible to appropriately select moving image reproduction with sound and moving image reproduction without sound.

  That is, the digital camera 1 has selection means for selecting whether to play a moving image with sound or a moving image without sound when playing a moving image. The selection means corresponds to the up / down keys of the multifunction cross key 30 shown in FIG.

  When the upper key of the cross key 30 is operated in the state where the moving image is partially reproduced in step S24, the moving image reproduction with sound is selected (step S26, step S40), and the moving image is displayed on the image monitor 34. At the same time, sound is generated from the speaker 36 (step S42). On the other hand, when the lower key of the cross key 30 is operated in the state where the moving image is partially reproduced in step S24, the soundless moving image reproduction is selected (step S26, step S40), and the moving image is displayed on the image monitor 34. However, the reproduction of audio is prohibited (step S44).

  In this embodiment, the up / down key of the multi-function cross key 30 is used to select the video playback with audio and the video playback without audio. However, a dedicated selection switch may be provided. A selection switch for selecting whether or not to reproduce the video and a selection switch for selecting whether or not to reproduce the video may be provided separately. Furthermore, it is also possible to select a still image with sound and a still image without sound even when the sound can be recorded even in the still image shooting mode and the sound can be reproduced during single frame playback of the still image.

  In this embodiment, a digital camera has been described. However, the present invention is not limited to a digital camera, and any device may be used as long as it is an image playback device having the above-described image playback function or a device including the image playback device.
