Definitions

  • the invention relates to an electronic time measuring device with an electronic image recording camera and an electronic screen for an electronic image display device.
  • Electronic timekeeping devices are used at sporting competitions, but other time-related events associated with the achievement of a goal can also be recorded and observed in this way.
  • Such a device is composed of several units, usually a timer (timer), a digital display board, a recording device (recorder), a printer (printer), a camera (video camera), an image display device with a screen (monitor) and the Finish line, which is usually formed by one or more light barriers. This light barrier, which represents the finish line, is not visible, only its interruption is registered by an electronic module (stopping the time).
  • the invention proposes that in order to display a vertical target line on the screen, the image signal for the screen in the central region of each image line is suppressed and replaced by an external potential (black or white level).
  • a television receiver is known with provisions for displaying auxiliary information on the screen of a picture display tube, in addition to the normal video signal information, with a screen blanking in connection with the reproduction of the Aid information is taken care of.
  • Other known television receivers also contain devices for displaying auxiliary characters for specifying the time, the date or the channel number to which the receiver is tuned.
  • the representation of alphanumeric characters for the channel tuning typically contains complex tuning systems and associated symbol generators, for example a voting display in the form of a vertical bar is generated when the receiver is tuned. The position of the bar with respect to the channel numbers on a scale next to the screen indicates the number of the channel to which the receiver is tuned.
  • the tuning system is a signal search system in which the tuning indicator bar moves across the screen depending on the tuning voltages generated in the channel search mode when the user operates the channel selector.
  • the present invention is based on a completely different consideration, and it does not relate to a device for television transmissions with which selected transmission channels can be displayed, nor is it an electronic display device as has been explained in more detail above.
  • the invention relates to a modern time measuring device, such as is used in sporting events and competitions.
  • the finish line which has to be passed or passed through at such competition events, is not visible, it is formed by a light barrier that cannot be photographed and that cannot be recorded with an electronic image recording device.
  • the electronic finish line has the task, on the one hand, of replacing a missing, natural finish line or of making an existing natural finish line that is obscured by the competitors or vehicles at the finish line (athletics, motorsport, cycling, etc.). Only this electronic finish line enables the finish to be precisely analyzed or evaluated. Nevertheless, there is a need and interest to be able to precisely observe and analyze the finish at such competitions and events, which of course is only possible if such a finish line is also visible. The invention creates a possibility for this.
  • the signal (pulse) controlling the line writing of the electron beam for the screen additionally controls a delay circuit or a timer whose output pulse corresponds to approximately half the period of the signal controlling the line writing and the output pulse of this first delay circuit or the first timer controls a second delay circuit or a second timer whose output pulse in the nano-second range switches this line to an external potential (black or white level) for the duration of this output pulse via an electronic switch in the line for the image signal.
  • the duration of the output pulses of both delay circuits or timers can be regulated, then the finish line can move within the screen can be shifted to the right or to the left and the strength of the finish line can also be adjusted.
  • the delay circuits or timing elements are expediently designed as monostable multivibrators (flip-flop).
  • a sporting event recorded by a recording camera 20 takes place in the target area of a sports arena (FIG. 3).
  • the timing 3 is shown on the screen 1 and also an electronic finish line 4, which is shown here as a vertical black line.
  • the recording camera 20 is aligned to the imaginary, invisible, formed by light rays target line 4 'of the target area, which runs across the track 21 (Fig 3).
  • the axis of the recording camera 20 lies in one plane with the target line 4 '.
  • the switching elements essential to the invention are shown in this FIG. 1:
  • the line 5 carrying the image signal supplied by the recording camera 20 leads via a video amplifier 6 to the picture tube of the image display device 2.
  • the line 7 carries the signal 8 causing the line writing on the screen 1 whose pulse duration is 64 ⁇ sec according to a uniform standard.
  • An electronic switch 9 is integrated in the line 5 carrying the image signal, one switching element 10 of which switches this line 5 through in order to conduct the image signal to the picture tube and the other switching element of which serves to interrupt the line 5 interrupted by the switching element 10 to an external potential 12 (black - or white level).
  • An inverter 15 lies between the two lines 13 and 14 controlling the switching elements 10 and 11.
  • the first flip-flop 18 is excited via line 17, which in turn drives the second flip-flop 19 after approximately 32 ⁇ sec, the output pulse 25 of which is approx. Is 400 nsec and the line 5, which carries the image signal, switches to an external potential 12 (black or white level) during this period of time via the switch 9.
  • the image signal is suppressed in each case in the middle of an image line, so that a black or white dot is written on the screen 1 in the central region, the sum of all dots of all lines of an image giving the vertical target line 4 visible here.
  • the duration of the pulses 24 and 25 can be changed via potentiometers, with the result that when the pulse 24 changes, the target line 4 on the screen shifts to the right or left, depending on whether the pulse duration is shortened or lengthened .
  • this pulse 24 changes the target line 4 shown on the screen becomes wider or narrower.
