Description

  The present invention relates to an imaging apparatus.

Conventional imaging devices such as a television camera and a still camera are provided with a display device (viewfinder) that allows a photographer to check a subject, an image frame, and a focus.
Multiple television cameras are used for program production and broadcast relay in the studio, and a red tally signal is sent from the switcher that selects video to the target camera (hereinafter referred to as the current) that is to be aired or recorded via the CCU. Alternatively, the cameraman tally and the large tally (hereinafter referred to as the front tally) on the front of the image pickup device are turned on in red, and the performer visually recognizes the front tally, recognizes the photographing camera, and aligns the line of sight (see Patent Document 1).
Also, a spare green tally is sent to the next on-air, next-recorded, or pre-recorded (hereinafter reserved) camera, and the tally on the viewfinder screen side or the tally on the back of the television camera is lit in green. Encourage photographers to respond.

JP 2002-271651 A

Traditionally, the performer cannot see the reserve green tally.
An object of the present invention is to provide a function that enables a performer to visually observe a preliminary green tally in order to solve the above-described problems.

  In order to solve the above problems, the present invention provides an imaging apparatus having a plurality of lenses and video display means, means for selecting videos of the plurality of imaging apparatuses, and a current selection signal and a preliminary selection signal for the selection means. Means for sending to the plurality of imaging devices; warning means for displaying the current selection signal in red on the front surface of the plurality of imaging devices; and red for displaying the current selection signal on the back of the video display means or on the back of the imaging device. Means for displaying the preliminary selection signal in green on the rear surface of the video display means or on the rear surface of the imaging device, wherein the preliminary selection signal is turned on when the active selection signal is off. In this case, the image pickup system is characterized in that warning means for displaying green is provided on the front surface of the lens or the image display means or the image pickup apparatus.

  When the on-air of the means for selecting the video or the recording target (hereinafter referred to as active) selection signal is on, a red alarm is displayed, and when the current selection signal is off, the on-air is next to the means for selecting the video or When a target camera (hereinafter referred to as “preliminary”) selection signal to be recorded next or preliminarily is turned on, an alarm display device that displays a green alarm or a lens or video display device comprising the alarm display device on the front surface Studio adapter or imaging device.

  As described above, according to the present invention, in a studio system that operates a plurality of cameras, the on-air / recording status, standby status, and back-shot camera status are displayed on the front tally, and the studio shooting personnel can switch the status and camera. Can be recognized.

The schematic diagram which shows the warning means (tally lamp) of one Example of this invention 1 is a block diagram illustrating an imaging system having an overall configuration according to an embodiment of the present invention. The block diagram which shows the drive circuit of one Example of this invention

  Hereinafter, an embodiment of the present invention will be described with reference to the schematic diagram showing the warning means (tally lamp) of the embodiment of the present invention in FIG. 1 and the block diagram showing the imaging system of the overall configuration of the present invention in FIG. To do.

  FIG. 1 is a schematic diagram showing a warning means (tally lamp) according to an embodiment of the present invention shown in FIG. 1, wherein Dr is a red LED and Dg is a green LED. The red LED Dr and the green LED Dg may be arranged in a checkered pattern as shown in FIG. 1 or may be arranged alternately, and the red LED Dr and the green LED Dg are small in number. May be added.

In FIG. 2, which is a block diagram showing an image pickup apparatus having the overall configuration of the present invention, 1A, 1B, and 1N are lenses, 2A, 2B, and 2N are cameras, and 3, 3A, 3B, and 3N are front tallys. 4A, 4B, and 4N are viewfinders (VF: display devices), 5A, 5B, and 5N are camera cables, 6A, 6B, and 6N are control units (CCU), and 7A 7B and 7N are video coaxial cables and tally cables, 8 is a video switcher, and 9 is a studio adapter.
Reference numerals 5A, 5B, and 5N denote camera cables such as a triax cable, an optical composite cable, or a coaxial power line composite cable.

As shown in FIG. 3 of the block diagram showing the drive circuit of one embodiment of the present invention, either the red LED Dr or the green LED Dg is selected according to the tally output signals R-Tally and G-Tally from the switcher 8. A drive circuit for lighting the lamp is provided inside the viewfinders 4A, 4B, 4N. As a result, when the red tally signal R-Tally is turned on from the switcher 8 to the on-air camera, the front tally 3 lights in red. If the green tally signal G-Tally is turned on to the standby camera while the red tally signal R-Tally is off, the front tally 3 is lit in green.
Since there are the IC1 of the inversion logic (INV) IC and the IC2 of the AND (AND) IC in FIG. 3, when the R-Tally is on, the G-Tally is turned on in red and not in green.
Since there are IC1 of inverted logic (INV) IC and IC2 of logical product (AND) IC, when R-Tally is turned on, even when G-Tally is turned on, it is lit red and green is not lit.

  The present invention makes it possible for the actors in the studio other than the cameraman to recognize the reserve green tally, and in particular, the performer knows in advance that the camera has been switched and is ready to match his eyes.

  In addition, since the current red tally is prioritized over the spare green tally, it is possible to match the line of sight to the current red tally camera without the performer getting lost.
