  Further, a circular cross key 8 is disposed inside the jog dial 7. The cross key 8 has an OK key 81 at the center position, an UP key 82 at the upper position, a DOWN key 83 at the lower position, a right key (direction key) 84 at the right position, and a left key (direction key) 85 at the left position. Yes.

  FIG. 4 is a block diagram showing a schematic configuration of the video photographing apparatus described with reference to FIGS.

  As shown in FIG. 4, the image capturing apparatus includes a CCD 101, a signal processing circuit 102, an encoder (JPEG / MPEG) 103, a memory 104, an HDD 105, a memory card 106, a decoder 107, an LCD driver 108, an LCD 51, a LAN controller 110, and a USB. A controller 111, a LAN terminal 112, a USB terminal 113, a CPU 114, and the like are provided. These are connected via a bus 115.

  In response to the operation of the still image record button 4, the CCD 101 converts light (still image) obtained through the lens 2 into an electrical signal. Alternatively, in response to the operation of the moving image record button 6, the CCD 101 converts light (moving image) obtained through the lens 2 into an electrical signal. The signal processing circuit 102 converts an electrical signal output from the CCD 101 into a digital signal. The encoder 103 encodes a digital signal of a still image into an image signal conforming to JPEG. Alternatively, the encoder 103 encodes a moving image digital signal into an MPEG-compliant image signal. The HDD 105 stores an image signal provided via the memory 104. Similarly, the removable memory card 106 also stores an image signal provided via the memory 104. The decoder 107 decodes the image signal provided via the memory. The LCD driver 108 controls the driving of the LCD 51 based on the decoded image signal and outputs the image signal on the liquid crystal display.

  At the time of reproducing the recorded image, the decoder 107 decodes the image signal provided from the HDD 105 or the memory card 106 via the memory 104. The LCD driver 108 controls the driving of the LCD 51 based on the decoded image signal, and outputs the image signal on the LCD 51.

  When an image recorded in the HDD 105 or the memory card 106 is transferred to an external device (such as a PC) or an image is received from an external device, the image is transmitted / received from the USB terminal 113 via the USB controller 111. Further, an encoded image can be directly transmitted / received to / from an image recording / reproducing apparatus such as a DVD recorder without using an external device such as a PC.

  In general, when transferring an image to a DVD recorder, the encoded moving image is decoded on the transmission side (video shooting device side), analog output from the video terminal or S terminal, and on the reception side (image recording / playback device side). Re-encode and save the analog signal. In this method, for example, it takes one hour to record an image recorded for one hour on a DVD or the like.

  However, in this video photographing apparatus, as described above, the encoded image can be transferred as compressed data to the image recording / reproducing apparatus via the network. Thereby, although it depends on the compression rate at the time of encoding, a transfer time of 1/10 or less of the actual recording time can be achieved. Moreover, since the image quality is not re-encoded, the high image quality state can be maintained. For example, when a transfer time of about 1/10 of the actual recording time is sufficient, a moving image recorded for 1 hour can be recorded on another recording medium in about 6 minutes. When a LAN is considered as a network, image data is transmitted / received by a LAN terminal 112 via a LAN controller 110. The data to be transferred may be audio data as well as moving images and still images.

  This video photographing apparatus includes an HDD 105 as a large-capacity storage unit. That is, various data (a huge number of still images and long-time moving images) can be stored in the HDD 105, and accordingly, high speed is required for sending and returning images. For this reason, in order to operate these without stress, the jog dial 7 and the cross key 8 are used. Corresponding to the rotation of the jog dial 7, the jog dial 7 outputs information on the rotation amount (rotation angle) and the rotation direction to the CPU 114 that controls the entire system. For example, the jog dial 7 outputs a pulse corresponding to a certain rotation angle. For example, when the jog dial 7 rotates n degrees, the jog dial 7 outputs one pulse. The CPU 114 counts the number of pulses per unit time and calculates a rotation angle (rotation speed) per unit time. As described above, the CPU 114 acquires the rotation information such as the rotation amount (rotation angle), the rotation direction, and the rotation speed of the jog dial 7, and controls various operations and the display on the LCD 51 based on the rotation information. To do. The cross key 8 presses the CPU 114 with the OK key 81 at the center position, the UP key 82 at the upper position, the DOWN key 83 at the lower position, the right key 84 at the right position, and the left at the left position. Tells the key 85 to be pressed. The CPU 114 controls various operations and controls the display on the LCD 51 based on each press on the cross key 8.

When an image file (moving image file) to be played back is selected from (active display only), the selected moving image file is displayed on the LCD 51, and thereafter, the other moving image files are sequentially displayed on the LCD 51. The display order can be selected randomly or in order of shooting date.

  Also, the playback mode is designated via the mode lever 11, the still image moving image continuous playback mode is designated by the jog dial 7 and the cross key 8, and a plurality of image files (stored in the HDD 105 by the jog dial 7 and the cross key 8 ( When an image file to be reproduced (still image file or moving image file) is selected from among the still image file and moving image file), the selected image file is displayed on the LCD 51, and thereafter, the other image files are sequentially displayed on the LCD 51. Is displayed. The display order can be selected randomly or in order of shooting date.

  FIG. 5 is a diagram showing an example of a playback menu displayed on the display unit by specifying the playback mode. When auto play (continuous playback) is selected from the playback menu, an auto play screen for specifying execution of auto play or detailed auto play settings is displayed. FIG. 6 is a diagram illustrating an example of a setting screen for specifying execution of auto play or detailed auto play settings. Via the setting screen, any of the above-described still image continuous reproduction mode, moving image continuous reproduction mode, and still image moving image continuous reproduction mode can be set. Also, the auto play playback interval can be set via this setting screen. FIG. 7 is a diagram showing an example of a playback interval setting screen for setting the playback interval of auto play.

  Next, an operation of selecting one file reproduction (random reproduction) and continuous reproduction (sequential reproduction) from the reproduction screen will be described.

  A playback mode is designated via the mode lever 11, and for example, a video file to be played back is selected from among a plurality of image files (still image files and video files) stored in the HDD 105 by the jog dial 7 and the cross key 8. The selected moving image file is displayed on the LCD 51. When the selected moving image file is displayed on the LCD 51, for example, when the DOWN key 83 of the cross key 8 is pressed, a one-file reproduction designation icon 202 and a continuous reproduction designation icon 201 as shown in FIGS. 8 and 9 are displayed. The These icons can be selected by the right key 84 and the left key 85 of the cross key 8. As shown in FIG. 8, “continuous playback” is displayed when the continuous playback designation icon 201 is selected, and “1 file” is displayed when the single file playback designation icon 202 is selected as shown in FIG.

  As shown in FIG. 9, when the OK key 81 of the cross key 8 is pressed with the one-file playback designation icon 202 selected, a one-file playback icon 204 is displayed as shown in FIG. File playback starts. That is, only the currently displayed moving image file is played back.

  As described above, it is possible to select one-file reproduction and continuous reproduction from a quick menu as shown in FIGS. 8 and 9 by a simple operation without going through the reproduction menu. This improves convenience.

  For example, in a camera using a magnetic tape as a recording medium, the captured moving image data is inevitably recorded in chronological order (the order of shooting). For this reason, when moving image reproduction is performed, continuous reproduction is always performed. On the other hand, in a camera using an HDD as a recording medium, captured moving image data is recorded as a single moving image file by one shooting start and stop. Therefore, it is possible to individually reproduce each moving image file or to reproduce a plurality of moving image files as if they were one moving image file. The video photographing apparatus described above can switch between single file reproduction and continuous reproduction with a simple operation.
