Description

  The present invention relates to an image reproduction display method and apparatus, and a photographing apparatus, and more particularly to an image reproduction display method and apparatus for reproducing a photographed image, and a photographing apparatus.

  Imaging apparatuses such as digital cameras and camera-equipped mobile phones that perform imaging using an image sensor such as a CCD or CMOS that accumulates electric charge according to the amount of light of the subject are widely used. In general, an image obtained from an image sensor is rectangular, and a photographer holds a photographing device in a horizontal posture when obtaining a horizontally long image, and holds a photographing device in a vertical posture when obtaining a vertically long image. To shoot.

  The photographing apparatus generally includes a liquid crystal display on the back of the camera body, and can display a through image as an electronic viewfinder or reproduce and check a photographed image.

  The liquid crystal display generally has a horizontally long rectangle and is displayed upright when an image shot in the horizontal position is displayed. The image shot in the vertical position is the same as when shooting the camera body. The image cannot be viewed in an upright state unless it is rotated and rotated 90.degree. Some models have an image processing function for rotating a display image by 90 °. In such a model, if this processing is applied to an image shot in a vertical orientation, all images can be displayed upright without rotating the camera body in subsequent playback display. Become.

On the other hand, there is known a silver halide camera that automatically distinguishes a vertical posture and a horizontal posture and changes a position where data such as date is copied onto a film (Patent Document 1). Further, a silver halide camera that automatically distinguishes the vertical posture and the horizontal posture and automatically switches the display in the finder is known (Patent Document 2). In addition, “Fuji Film Photo Player AP-1” (product name) that has been commercially available in the past has a “frame advance playback” mode in which frame advance is performed manually, and a “slide show playback” mode in which frame advance is automatically performed (automatic). Etc.), and these modes could be selectively switched to display an image of the loaded film cartridge on a connected television.

Although not shown, a card slot for mounting a memory card 75 (see FIG. 3) is provided on the left-hand side surface of the camera body 11.

  Further, on the upper surface of the camera body 11, a ring-shaped mode switching dial 18 for switching a photographing mode such as auto or manual by rotating, a shutter button 19 provided at the center, and a power switch 20 are disposed. ing.

  As shown in FIG. 2, on the back of the camera body 11, a liquid crystal display (LCD) 22, a zoom button 24, a multi-function cross button 26, a menu / execution button 27, a liquid crystal display / return button 28, and a playback mode button 31 are displayed. , A photo mode button 32 is provided.

  The LCD 22 has a rectangular shape whose screen 22a is long in the horizontal direction (horizontal direction), and its aspect ratio is about 1.5, which is substantially the same as the aspect ratio of an image taken by a CCD, which will be described later. The LCD 22 is used as an electronic viewfinder during photographing, and displays a photographed image preview image, a reproduced image read from the memory card 75, and the like on the screen 22a. Further, menu selection using the cross button 26, setting of various items in each menu, and the like are also performed using the screen 22a of the LCD 22.

  The zoom button 24 performs zooming in the telephoto (TELE) direction by pressing the right end portion 24a, and performs zooming in the wide-angle (WIDE) direction by pressing the left end portion 24b. The cross button 26 can input instructions in the corresponding four directions (up, down, left, and right) by pressing one of the top, bottom, left, and right edges. It is used as an operation button for instructing change, and as means for instructing electronic zoom magnification adjustment and playback frame return / return.

  The menu / execution button 27 is used when transitioning from the normal screen to the menu screen in each mode, as well as when confirming the selection contents and instructing execution (confirmation) of processing. The liquid crystal display / return button 28 turns off the backlight of the LCD 22 in order to save energy when a certain period of time elapses in the shooting mode or the playback mode. However, when pressed in this unlit state, the backlight of the LCD 22 is turned on. The liquid crystal display / return button 28 is used to cancel (cancel) the item selected from the menu or to return to the previous operation state.

  When the reproduction mode button 31 is pressed, the captured image is reproduced and displayed on the LCD 22. In this case, when the right end portion 24a or the left end portion 24b of the zoom button 24 is pressed, a manual frame advance reproduction mode (hereinafter referred to as frame advance reproduction mode) in which frame advance is manually performed is set. As will be described in detail later, when the menu / execution button 27 is pressed in this frame advance playback mode, a menu screen is displayed, and an auto play mode, which is an automatic frame advance playback mode for automatically performing frame advance during playback, is selected. be able to.

  In FIG. 3 showing the electrical configuration of the digital camera 10, a CCD 50, which is an imaging means for imaging subject light that has passed through the photographic lens 12, is disposed behind the photographic lens 12. The CCD 50 is connected via a timing generator (TG) 52 to a system controller 51 that is a control means for controlling the entire digital camera 10.

  The system controller 51 controls the TG 52 to generate a timing signal (clock pulse). The CCD 50 is driven by a timing signal (clock pulse) input from the TG 52. The imaging signal output from the CCD 50 is input to a correlated double sampling circuit (CDS) 53 and output as R, G, and B image data corresponding to the accumulated charge amount of each cell of the CCD 50. Image data output from the CDS 53 is amplified by an amplifier (AMP) 54 and converted from analog signals to digital signal image data by an A / D converter (A / D) 55.

  The image input controller 56 is connected to the system controller 51 via the data bus 57. In addition, a memory 58 is connected to the data bus 57. As the memory 58, for example, an SDRAM is used. The system controller 51 controls the image input controller 56 to store the image data output from the A / D 55 in the memory 58. This image data is displayed as a through image on the LCD 22 via the image reproduction processing circuit 59 and the LCD driver 60.

  The image reproduction processing circuit 59 sends the image data as it is to the LCD driver 60 without performing any processing on the image data at the time of displaying the through image. However, as will be described in detail later, the image reproduction processing circuit 59 temporarily stores it in the memory card 75. When the reproduced image data is read out and displayed on the LCD 22, image processing such as rotation is performed depending on the type of the reproduction mode.

  When a television (TV) monitor 64 is connected to the video output terminal 62, the connection detection switch 65 detects this, and the image reproduction processing circuit 59 inputs the image data to the video encoder 66. The video encoder 66 converts the image data into an NTSC signal and sends it to the TV monitor 64, and the reproduced image is displayed on the TV monitor 64.

  The image signal processing circuit 68 performs various image processing such as gradation conversion, white balance correction, and γ correction processing when image data is stored in the memory 58. Further, the YC conversion processing circuit 70 converts the image data that has been subjected to various types of image processing into a luminance signal Y and color difference signals Cr and Cb.

  The compression / decompression processing circuit 72 performs compression processing on the image data converted by the YC conversion processing circuit 70 in a predetermined compression format (for example, JPEG format). Further, at the time of moving image shooting, compression processing is performed in a compression format such as MPEG format. The compressed image data (still image data and moving image data) is stored in the memory card 75 via the media controller 74.

  The system controller 51 includes a strobe circuit 78 for driving the strobe light emitting unit 14, the shutter button 19, the power switch 20, the zoom button 24, the multifunction cross button 26, the liquid crystal display button 28, and the menu / execution button 27. , An operation unit 79 including a cancel / return button 32 and the like, and a vertical / horizontal posture detecting device 80 for detecting whether the posture of the camera body 11 is vertical or horizontal.

  As shown in FIG. 4, the vertical / horizontal posture detection device 80 has mercury 82 sealed in an arcuate cylinder 81. The cylinder 81 is provided with a pair of electrodes 83 to 85 at three locations, an intermediate portion and both ends. In the horizontal position (A) in which the user holds the camera body 11 in the horizontal position, the horizontal position (B) in which the mercury 82 is in the middle of the cylinder 81 and the electrode 83 is short-circuited, and the user holds the camera body 11 in the vertical position. ), The mercury 82 moves to the end of the cylinder 81 and either the electrode 84 or the electrode 85 is short-circuited. The system controller 51 monitors the electrodes 83 to 85 of the vertical / horizontal posture detection device 80 at the time of shooting, specifies the posture of the camera body 11 at the time of shooting depending on which electrode is short-circuited, and uses this body posture information as a shot image. Is added to the image data as one of the additional information.

  In order to reproduce an image captured by the digital camera 10 configured as described above, first, as shown in FIG. 5, the reproduction mode button 31 is pressed (st1). When the auto play mode is not selected (st2), the frame advance playback mode is entered as it is (st3), so the right end 24a or the left end 24b of the zoom button 24 is pressed to manually select an image to be played back.

  Each time the right end portion 24a or the left end portion 24b is pressed, the captured image data stored in the memory card 75 is read one frame at a time in the shooting order and sent to the image reproduction processing circuit 59. Since the image reproduction processing circuit 59 sends the image data to the LCD driver 60 without any modification, the image is reproduced and displayed on the LCD 22 with the posture at the time of photographing as shown in FIG. Note that an image 90 shown in FIG. 9A shows an example of a horizontal posture, and an image 91 shown in FIG.

  In this way, in frame-by-frame playback mode, playback is displayed as it is in the same state as at the time of shooting, so you can watch without feeling uncomfortable, you can understand well what kind of state you shot and fully capture the shot image I can confirm.

  When the menu / execution button 27 is pressed from the frame advance playback mode, a menu screen 34 is displayed as shown in FIG. When the cross button 26 is operated to move the cursor 40 to the icon 38 indicating the auto play mode among the icons displayed on the menu bar 36, the icon 38 is highlighted.

  When the menu / execution button 27 is pressed from this state, four display methods 44 to 47 in the auto play mode are displayed. The display methods 44 and 45 are common in that fade-in and fade-out of each frame are performed obliquely, but the display method 45 has a frame display interval shorter than that of the display method 44. In addition, the display methods 46 and 47 are common in that each frame is switched instantaneously, but the display method 47 has a frame display interval shorter than the display method 46.

  When a rectangular cursor 48 is moved up and down using the cross button 26 and the cursor 48 is moved to the display method 47, for example, the picture drawn inside the strip of the display method 47 is inverted. When the menu / execution button 27 is pressed from this state, the auto play mode by the display method 47 is started (st2).

  Image data and its additional information are read from the memory card 75 in the shooting order at regular time intervals and sent to the image reproduction processing circuit 59 (st4, 5). The image reproduction processing circuit 59 refers to the posture information in the additional information of the first frame image data, and confirms whether the posture is the horizontal posture or the vertical posture (st6). Even in the same vertical position, there are a first vertical position in which the strobe light emitting unit 14 is on the upper side and a second vertical position on the lower side. In the first vertical position, the electrode 84 is short-circuited, and in the second vertical position, the electrode 85. Is short-circuited, so the posture information is different. When illuminating a subject with auxiliary light, it is natural to irradiate from above, so it is common to photograph in a first vertical posture.

  In the horizontal posture, the image reproduction processing circuit 59 sends the image data to the LCD driver 60 without performing any image processing as in the frame advance reproduction mode. In the case of the vertical posture, the image reproduction processing circuit 59 refers to the posture information included in the additional information of the image data, and in the case of the first vertical posture, the image is rotated 90 ° and displayed. In the second vertical posture, the image data is converted and sent to the LCD driver 60 so that the image is rotated by 270 ° (st7).

  As a result, as shown in FIG. 8, the horizontal posture image 90 taken in the horizontal posture is reproduced and displayed for a certain period of time in the horizontal posture as it is (A), and the vertical posture image 91 taken in the vertical posture is upright. The state is reproduced and displayed for a predetermined time (B) (st8). The fixed time is 1 second. Thereafter, if the second and subsequent images are taken in the horizontal posture, the image is left as it is. If the image is taken in the vertical posture, the image is rotated by 90 ° or 270 °, and 1 is displayed on the LCD 22. The information is sequentially displayed every second (st9).

  When the reproduction of all the shot frames stored in the memory card 75 is completed (st10), the reproduction operation in the auto play mode is stopped. In this state, if the right end 24a or the left end 24b of the zoom button 24 is pressed, the frame advance playback mode is set. If the auto play mode is selected, the auto play mode is set again.

  Further, when the TV monitor 64 is connected to the video output terminal 62 (the connection detection switch 65 is on) and the playback mode is set, the image playback processing circuit 59 does not set the auto play mode. With reference to the posture information in the additional information, the image is rotated by 90 ° in the case of the first vertical posture, and the image is rotated by 270 ° in the case of the second vertical posture. Then, the image data is converted and sent to the video encoder 66 so as to be displayed. The video encoder 66 converts the image data into an NTSC signal and sends it to the TV monitor 64, and the reproduced image is displayed on the TV monitor 64.

  In the above embodiment, as shown in FIG. 8, the entire vertical posture image 91 is displayed. However, there is an advantage that the entire vertical posture image 91 can be confirmed at one time, but the vertical posture image 91 is displayed. Is displayed in a small size, it is difficult to confirm the vertical posture image 91 depending on the design. In addition, there is a disadvantage that blank areas 92 and 93 are generated on the left and right of the vertical posture image 91.

  Therefore, when the auto play mode is set or when the TV monitor 64 is connected, as shown in FIG. 9, the entire vertical posture image 91 is gradually displayed while being automatically tilted at a predetermined speed. It is preferable to perform display. In this auto tilt display, the length of the short side of the vertical posture image 91 matches the length of the long side of the screen of the LCD 22 or the TV monitor 64, and the vertical posture image 91 is gradually tilted while being automatically tilted at a predetermined speed. Since the entire image is displayed, the vertical posture image 91 can be confirmed more reliably.

  In the auto-tilt display, the speed at which the vertical posture image 91 is tilted is 1 second from the start of display of the upper part of the image to the end of display of the lower part of the image. The tilt direction is generally started from the upper part of the image, but may be displayed from the lower part of the image. In addition, it is preferable that the normal display in which the entire vertical posture image 91 is displayed at once and the auto tilt display can be switched at any time.

  Next, in FIG. 10 showing the second embodiment of the present invention, an image reproduction display device 100 includes a device main body 101 and an LCD 102 rotatably attached to the upper surface. The internal configuration of the apparatus main body 101 is obtained by removing the configuration related to imaging (such as a photographing lens, CCD, and strobe circuit) from the first embodiment, and limiting the function only to that related to reproduction.

  When the memory card 75 is inserted into the memory slot 104 provided on the front surface of the apparatus main body 101, the image data stored in the memory card 75 is read, and the image is reproduced and displayed on the LCD 102. By default, the mode is a manual frame advance playback mode in which frame advance is performed manually. By pressing the feed button 106 and the return button 107, an arbitrary frame can be viewed at a pace desired by the user.

  In the manual frame advance playback mode, as in the first embodiment, the posture information added to the image data is ignored and displayed on the LCD 102 with the posture at the time of shooting. When the mode selection dial 108 is operated to set the auto play mode in which the frame advance is automatically performed, the frame advance is performed at regular intervals, and the image having the vertical posture information is 90 ° so that the image looks upright. Alternatively, the image is displayed on the LCD 102 after being rotated by 270 °. In this auto play mode, the size of the display image is reduced, but a normal mode in which the entire image is displayed at once and a tilt mode in which the auto tilt display is performed can be selected.

  In addition, when a TV monitor 64 such as a liquid crystal television is connected to the video output terminal 109 provided on the side surface of the apparatus main body 101, the auto play mode is automatically set, and images in the memory card 75 are sequentially displayed at regular time intervals. Is displayed.

  In the embodiment described above, the display time of each image in the auto play mode is 1 second. However, the present invention is not limited to this, and may be 0.5 seconds, for example.
