Description

  The present invention relates to a video camera device that captures an image, and more particularly to a video camera device having a switching recording / reproducing function of a plurality of broadcasting systems.

  Some conventional video camera apparatuses are provided with a technique that enables a single camera to cope with a plurality of broadcasting systems by providing a switching function to the video camera (see Patent Document 1).

  Hereinafter, a conventional method for dealing with a plurality of broadcasting systems will be described with reference to FIG.

  Figure 1 shows a multi-mode camera-integrated digital VTR that can handle camera shooting, compressed signal processing, and VTR recording in multiple TV standards for standard broadcasting and high-definition television (HDTV) broadcasting. The configuration is shown.

  In FIG. 1, a subject image is photoelectrically converted by a CCD as a solid-state imaging device built in the HDTV camera 101, and is output as a high-definition HD signal with a large amount of information. For example, in the studio standard, this HD signal has 1920 H × 1035 V pixels and the sampling frequency is 75.3 MHz. This HD signal is divided into two, one of which is input as it is to the imaging mode selection circuit 102 and the other is input to a system converter 103 such as down-conversion.

  This system converter 103 reduces information in order to convert HD signals into standard broadcast systems such as NTSC and PAL.

  The photographer selects and inputs a broadcast system desired to be recorded from the operation panel 104, and controls the broadcast system converter 103 under the control of the system controller 105, thereby enabling photographing in the desired broadcast system.

In this conventional example, it has also been proposed to display information on the selection state on the CVF of the main body.

  However, the case has the following problems.

  It is considered that switching between broadcast systems is most often used when you want to create and shoot programs for multiple broadcast areas with a single video camera. In such a case, it is difficult to collect enormous shooting costs, and there is a risk that the user will suffer an extremely large loss.

  In order to avoid this danger, a measure is generally taken to indicate to the photographer which broadcast system is selected on the display device of the main body.

  However, since the display device also serves as a monitor for the image to be taken, if it is displayed in a conspicuous form at all times, it will interfere with the photographing, leading to disadvantages for the photographer and cannot be made in a large conspicuous form. There is a considerable risk of shooting.

  In addition, it is conceivable that a display is made so as to show which broadcasting system is selected when the power is turned on each time, and then the display is switched to the normal display. However, since the operation is performed every time, the appearance becomes troublesome.

  The object of the first invention according to the present application is not only the display of the selected state on a normal display device, but also the switching history of the broadcasting method of the video camera device, in the video camera device capable of switching and recording the broadcasting method. By using the display method according to the condition as a judgment condition based on how much time has passed since the power was last turned on, the photographer may mistakenly recognize the broadcasting system and shoot The present invention proposes a guidance method that prevents the display on the display device from becoming troublesome.

  In order to achieve the above object, the first invention according to the present application includes a broadcasting system switching means for switching a broadcasting system, an internal clock means for engraving the date even in a power-off state, and a time when the power is turned off after switching the broadcasting system. Broadcast system switching date holding means for holding the date, information from the broadcasting system switching date holding means when the power is subsequently turned on, elapsed period calculation means for calculating a period elapsed from the internal clock means, and elapsed period calculation The elapsed time determination means for comparing the information from the means with the specified period to determine whether the period is longer or shorter than the specified time, and the normal display that is unlikely to hinder the captured image monitor according to the result of the elapsed period determination means. Broadcasting method display switching means for switching between the first display format and the second noticeable display format, and when the second display format is selected, the broadcasting method It characterized in that it comprises a broadcast mode switching date reset means for resetting the date holding means switching.

  If the broadcasting system has never been switched after purchasing the video camera, the information in the broadcasting system switching date holding means is in an initial state, so there is no need to guide the selection of the broadcasting system when the power is turned on. The elapsed time determination means controls the broadcast system display selection means to select the first display format for normal display.

  On the other hand, there is retained information in the broadcast system switching date retaining means, and as a result of the elapsed period determining means for comparing the information from the elapsed period calculating means to be compared with the internal clock means and the defined period, from the defined period If it is long, the unused period after switching the broadcasting system is long and the photographer determines that the previously set broadcasting system is not stored, and the broadcasting system display switching means is the broadcast currently selected by the photographer when the power is turned on. The broadcasting system is guided by the second display means that conveys the system prominently. After the guidance, the information in the broadcasting system switching date holding unit is reset by the broadcasting system switching date reset unit.

  If the elapsed time from the time the power is turned off after switching the broadcasting system does not exceed the specified time, the broadcasting system display switching judgment means uses the information from the elapsed period judgment means to indicate that the broadcaster has previously set the broadcast It is determined that the system is stored because the period is short, and the broadcast system display switching means is controlled to guide the broadcast system by the first display means that displays the normal display that is not troublesome to the photographer when the power is turned on.

  The display of what is currently selected as the broadcast format, and a noticeable display that is easy to understand for the photographer, as a criterion for determining how much time has elapsed since the power was turned off after the setting was changed By selectively switching the display that does not interfere with the monitor of the photographed image, it is usually not troublesome, and if the photographer is likely to have forgotten, it is displayed as a conspicuous display to prevent erroneous shooting by mistakenly broadcasting Make it possible.

  As described above, in addition to the normal broadcasting system selection status display, it is necessary to compare the elapsed time after the power is turned off and the specified time since the broadcasting system was last set, and to inform the user of the current selection status Only when it is determined that the display will be greatly conspicuous when the power is turned on, it will not increase the size of the broadcast system selection status display on the display device in the normal state, and each time the power is turned on Without this, it is possible to effectively inform the photographer of the current broadcasting system selection state.
