Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a recording mechanism for a video camera that prevents shooting errors during continuous shooting.

[Summary of the invention] The present invention provides a recording mechanism for a video camera that has an electronic viewfinder, and when a take-pause mode is selected, a still image immediately before the take-pause mode is displayed on the electronic view-finder, thereby changing the recording mechanism from the take-pause mode to the take-pause mode. It is possible to clearly visually recognize whether or not the mode switching operation has been performed appropriately, and it is possible to prevent shooting errors during continuous shooting.

[Prior Art] In a conventional video camera, a subject photographed by a camera unit is displayed on a CRT of an electronic viewfinder. Inside the viewing window of the electronic viewfinder
Recording indicator lamps are installed around the CRT. When a subject is displayed on the CRT and the recording mode is selected, the recording display lamp lights up to indicate that the camera is in recording mode. If Rec Pause mode is selected in this state, the recording display lamp will turn off and the Rec Pause mode will be displayed.
When the recording pause mode is canceled and the recording mode is selected again, the recording display lamp is turned on again to recognize whether or not the recording mode is in effect.

[Problems to be solved by the invention] However, the rect pause mode is recognized only by the turning off of the recording display lamp, and even in the rect pause mode, the CRT does not display the video of the object that the camera unit is currently capturing. It is being shown. Because the photographer is focused on the CRT to capture the next subject, he or she may overlook the recording indicator lamp turning off or on. There is a drawback in that even if the mode remains in the rectification mode without switching to the rectification pose mode due to a mistake in the switching operation to the rectification pose mode, the photographer may misunderstand that it is in the rectification pose mode and may make a photographing error.

Therefore, it is an object of the present invention to provide a recording mechanism for a video camera that prevents the above-mentioned shooting mistakes during continuous shooting.

[Means for Solving the Problems] The configuration of the present invention to achieve the above object is such that in a recording mechanism of a video camera having an electronic viewfinder, when a take pause mode is selected, a still image immediately before the take pause mode is displayed. is characterized in that it is configured to be displayed on the electronic viewfinder.

[Effect] Therefore, when the rec pause mode is selected,
A still image is displayed on the electronic viewfinder, clearly indicating that the rec pause mode has been selected.
