Description

  The present invention relates to a video recording / reproducing apparatus having a function of confirming a captured still image during moving image shooting, a control method thereof, and a computer program.

  Many conventional digital video cameras and the like include an electronic view finder (EVF) and a liquid crystal display panel that can rotate with respect to the camera body.

  Because of the size of the liquid crystal display panel, you can shoot while checking the image with both eyes, and always hold a digital video camera in front of you, such as when shooting at a high or low position or with your hand extended. There is an advantage that it is possible to shoot at various angles at least, and it is generally used widely. On the other hand, EVF is used to shoot while confirming the image of the subject to be photographed by looking into the EVF with the eyecup when the liquid crystal display panel is difficult to see due to the light entering under fine weather. ing.

  In recent digital video cameras, when the liquid crystal display panel is closed to the camera body, an image is displayed on the EVF. When the liquid crystal display panel is opened from the camera body, the image is displayed on the liquid crystal display panel and the EVF is displayed. There are many specifications that can no longer be displayed. However, in some cases, such as the face-to-face shooting mode, when the liquid crystal display panel is oriented in the imaging direction or the direction of the person to be photographed, there are specifications that display images on both the liquid crystal display panel and the EVF.

  By the way, although a digital video camera is originally a device for moving image shooting, there are many models capable of shooting still images. Conversely, some digital still cameras can shoot not only still images but also moving images. In addition, there are models that can perform still image shooting simultaneously during moving image shooting.

  However, when taking and recording still images during moving image shooting, it is very difficult to display each captured image in a state that is easy for the user to view. In order to solve this problem, for example, Patent Document 1 discloses a method of confirming a captured still image without interrupting moving image display using two display devices.

JP-A-10-32734

  For example, at the time of still image shooting with a digital video camera, as with a digital still camera, a still image is shot by pressing a shutter button at an arbitrary timing while watching a shooting target object with a liquid crystal display panel or EVF.

  In addition, in digital video cameras that can take still images during movie recording, the current movie display is interrupted and the still image is displayed temporarily in order to check the still images taken during movie shooting. Alternatively, a method of displaying a still image by a picture-in-picture or the like in a part of the moving image display is adopted. However, such a display form is not sufficient for viewing both moving images and still images.

  Therefore, it can be conceived that both the EVF and the liquid crystal display panel are set in a display state, and a moving image is displayed on one side and a still image is displayed on the other side. It has become a difficult structure to monitor both panels. In other words, when viewing with the EVF, there is a case in which the distance to the liquid crystal display panel is too short and the clear viewing distance may not be obtained.

  Even if it is a large casing and there is a distance to the liquid crystal display panel and it can be seen as a clear viewing distance, if you look at the liquid crystal display panel with the other eye while looking through the EVF, the two images will overlap In particular, it is difficult to clearly see the overlapping portion particularly on the liquid crystal display panel side.

  Hereinafter, a display example in the digital video camera of the present embodiment will be described with reference to FIG. FIG. 4A shows a display example when the present invention is not applied for comparison. Reference numeral 401 denotes an image obtained by looking into the EVF 202 with the right eye 301, and the image displayed on the LCD 303 in the EVF 202 is viewed through the eyepiece lens 302.

  Reference numeral 402 denotes an image obtained by viewing the display surface of the liquid crystal display panel 208 with the left eye 305. Here, it is a display after the shutter button 210 is pressed, and the photographed still image is displayed on the entire display surface of the liquid crystal display panel 208.

  As can be seen, when two adjacent display units (EVF 202, liquid crystal display panel 208) are viewed with the left and right eyes, that is, when looking at the EVF 202 with the right eye 301 and viewing the liquid crystal display panel 208 with the left eye 305. It was difficult to clearly see the overlapping portion of the two images, particularly the overlapping portion on the liquid crystal display panel 208 side.

(Offset display measures)
On the other hand, FIG. 4B is a display example when the present invention is applied, in which offset display countermeasures are taken. Similar to the video 401, 411 is a video obtained by looking into the EVF 202 with the right eye 301, and a moving image is displayed.

  Reference numeral 412 denotes an image obtained by viewing the display surface of the liquid crystal display panel 208 with the left eye 305. Here, the display after the shutter button 210 is pressed is different from the image 402 so that the captured still image 412 is not the entire display surface of the liquid crystal display panel 208 but the moving image 411 of the EVF 202 is avoided. The aspect ratio is offset as it is.

  Thereby, it is possible to eliminate the overlapping portion in the video viewed with the left and right eyes, and to simultaneously view the moving image and the entire captured still image.

  Reference numeral 413 denotes a background color display. As a result of the offset display as in the video 412, the photographed still image is displayed in a reduced size, so that an empty background is filled. Of course, the color of the background color display 413 may be any color.

(Gain adjustment measures)
FIG. 4C shows a display example when the present invention is applied, in which gain adjustment measures are taken. Similar to the images 401 and 411, 421 is an image obtained by looking into the EVF 202 with the right eye 301, and a moving image is displayed.

  Here, as shown in FIG. 4B, the video (still image) 412 is not offset and the overlapping portion of the images viewed with the left and right eyes is not eliminated, but the moving image side is displayed when the still image is displayed. By lowering (decreasing) the brightness of the image, the visibility of the still image of the overlapping portion is increased. Although this method cannot eliminate the overlapped portion, the strength of the video information from the right eye 301 looking into the EVF 202 is reduced without performing still image display resolution conversion processing or the like. The recognizability of the overlapping portion of the video 422 displayed on the display surface of the liquid crystal display panel 208 viewed in FIG.

  Reference numeral 422 denotes an image obtained by viewing the display surface of the liquid crystal display panel 208 with the left eye 305. Here, it is a display after the shutter button 210 is pressed, and the display is the same as the video 402.

  As described above, according to the digital video camera of this embodiment, when the EVF 202 and the liquid crystal display panel 208 that are close to each other are viewed with both eyes, the liquid crystal display panel 208 side is offset to display an overlapping portion of the display. This is a still image shooting result without interrupting the moving image display during shooting, because it is possible to increase the visibility of the still image by avoiding the image or reducing the brightness of the display on the EVF 202 side. It is possible to improve stillness of still images and to confirm both moving images and still images at the same time.

(Second Embodiment)
The second embodiment is characterized not only in consideration of the overlapping portion of the display as in the first embodiment but also in the control of display contents on the liquid crystal display panel.

  Table 1 shows an example of each state when still image shooting is performed during moving image shooting and a display state in EVF 202 / liquid crystal display panel 208 / line output 212 (external television monitor).

Also at this time, the display on the EVF 202, the liquid crystal display panel 208, and the line output connector 212 (external television monitor) is all “moving image”.

  Reference numeral 5-3 denotes a moving image shooting state. At this time, all the displays on the EVF 202, the liquid crystal display panel 208, and the line output connector 212 (external television monitor) are “moving images”.

  Reference numeral 5-4 denotes a state in which the shutter button 210 is pressed and a still image shooting is instructed. The “moving image” is continuously displayed on the EVF 202, and the “still image” is displayed on the liquid crystal display panel 208. The The line output 212 can select and display “moving image, still image, or moving image and still image”. The display selection for the line output 212 is determined separately by selecting a menu by the user operating the operation button 211. As a result, it is possible to check the captured still image by displaying the captured “still image” on the liquid crystal display panel 208 while continuously capturing the moving image and confirming the “moving image” with the EVF 202. For the line output 212, an output display form can be appropriately selected according to the purpose of use of the user.

  Reference numeral 5-5 denotes a moving image shooting continuation state, in which “moving image” is continuously displayed on the EVF 202, and “still image” display is switched to “moving image” display on the liquid crystal display panel 208. The timing for switching is set separately, and after the still image is captured in 5-4 and “still image” is displayed, the display is switched to “moving image” after the set time has elapsed. The line output 212 can select and display “moving image, still image, or moving image and still image”. The display selection for the line output 212 is determined separately by selecting a menu by the user operating the operation button 211. As a result, the moving image shooting is continued and the “moving image” is confirmed by the EVF 202, the captured “still image” is displayed on the liquid crystal display panel 208 for a certain period of time, then switched to “moving image”, and the EVF 202 is viewed. Even by looking at the display panel 208, video shooting can be continuously performed. For the line output 212, an output display form can be appropriately selected according to the purpose of use of the user.

  Reference numeral 5-6 denotes a shutter continuous shooting state, that is, a state in which the shutter button 210 is continuously pressed to continuously shoot still images, and “moving image” is continuously displayed on the EVF 202. In 208, the photographed still images are displayed one by one while being switched one after another. Alternatively, it is also possible to display the still images taken continuously in addition to the thumbnail list display as a “thumbnail” display instead of switching one by one. The line output 212 can select and display “moving image, still image, still image thumbnail, or moving image and still image”. The display selection for the line output 212 is determined separately by selecting a menu by the user operating the operation button 211. As a result, it is possible to confirm the captured image by displaying the captured “still image” or “still image thumbnail” display on the liquid crystal display panel 208 while continuously capturing the moving image and confirming the “moving image” with the EVF 202. it can. For the line output 212, an output display form can be appropriately selected according to the purpose of use of the user.

  Reference numeral 5-7 denotes a moving image shooting continuation state, in which “moving image” is continuously displayed on the EVF 202, and the “display” or “thumbnail” display is switched to the “moving image” display on the liquid crystal display panel 208. The timing for switching is set separately, and after the last “still image” or “thumbnail” displayed in 5-6 is displayed, the display is switched to “moving image” after the set time has elapsed. The line output 212 can select and display “moving image or still image, or thumbnail, moving image and still image”. The display selection for the line output 212 is determined separately by selecting a menu by the user operating the operation button 211. As a result, while the video shooting is continued and the “video” is confirmed by the EVF 202, the last “still image” or “thumbnail” display is displayed on the liquid crystal display panel 208 for a certain period of time and then switched to “video”. Then, it is possible to continuously perform moving image shooting by looking at the EVF 202 or by looking at the liquid crystal display panel 208. For the line output 212, an output display form can be appropriately selected according to the purpose of use of the user.

  Reference numeral 5-8 denotes a photographing stop state, and “moving image” is displayed on the EVF 202 and the liquid crystal display panel 208 as in the case of 5-1, but moving image recording is in a standby state. For the line output 212, an output display form can be appropriately selected according to the purpose of use of the user.

  As described above, according to the digital video camera of the present embodiment, as described in the first embodiment, it is only necessary to avoid the overlapping portion of the display or increase the visibility on the still image side. For still images that are shot continuously, display thumbnails or switch to movies again to give a wider range of methods for checking videos and still images without interrupting the video display during shooting. The shooting mode can be made flexible.

(Third embodiment)
In the third embodiment, attention is paid not only to consideration of overlapping portions of the display as in the first embodiment, but also to adjusting the (clear vision) distance to the display image viewed with the left and right eyes. is there.

  As shown in FIG. 3, the left eye 305 directly looks at the display surface of the liquid crystal display panel 208, but the right eye 301 sees the virtual image 304 of the LCD 303 through the eyepiece lens 302 in the EVF 202.

  Here, if the distance to the display surface of the liquid crystal display panel 208 and the distance to the virtual image 304 are different, the diopter adjustment in the left and right eyes is shifted, so the user switches the line of sight to see the left and right images respectively. At this time, it is necessary to adjust the focus of the eye by the amount of deviation, which is very difficult to see.

  In order to improve this situation, the diopter adjustment slider 203 is slid and adjusted in the optical axis direction of the EVF 202 to change the distance to the virtual image 304 and to be the same as the distance to the display surface of the liquid crystal display panel 208. To a degree.

  Note that the distance between the display surface of the liquid crystal display panel 208 and the virtual image 304 does not always match because there is a diopter difference between the left and right eyes for each user.

  As described above, according to the digital video camera of this embodiment, the diopter adjustment on the EVF 202 side is performed, and the display surface of the liquid crystal display panel 208 and the display surface of the virtual image 304 by the EVF 202 are matched (adjusted). Therefore, the clear visibility distance of each display surface is matched to realize further improvement of visibility.

  On the other hand, in order to perform the above adjustment, the distance to the liquid crystal display panel 208 is short when looking at the EVF 202 in order to reduce the size of the housing in an actual product. It is necessary to consider a case where a problem such as a short distance does not occur. In that sense, the distance from the front of the eyepiece lens 302 of the EVF 202 to the display surface of the liquid crystal display panel 208 needs to be more than the clear vision distance, and a digital video camera that secures the distance is effective. .
