Abstract

PURPOSE:To completely remove the failure in recording, by not starting the recording, if the level of luminance signal at the camera trigger of image recording is low, and informing it to the operator. CONSTITUTION:If the heater of a pickup tube VT is not sufficiently heated and the luminance signal does not reach to a certain level, the output of the converter C1 is always at high level, and when the camera trigger is made and the input R of FF is at low level, the input S remains at low level, the output Q of FF is not at high level and no recording is started. Since the output of the comparator C1 is at high level, the light emitting diode LED illuminates. When the heater of pickup tube VT is sufficiently heated and the luminance signal is produced, the input S of FF is at high level and recording is started. When the recording is once started, the recording is not stopped even if the light emitting diode LED illuminates. The operator can know too dark objective by observing the light emitting diode LED during recording.
