本発明はテレビジョンカメラ装置に関し、特に撮像管の
各電極の調整を容易にした新規なテレビジョンカメラ装
置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a television camera apparatus, and more particularly to a novel television camera apparatus in which adjustment of each electrode of an image pickup tube is facilitated.
従来、テレビジョンカメラ装置においてビーム量の設定

ビーム量以上に相当する光源である被写体を撮像し、そ
の映像信号を波形モニターで観察しながら設定しようと
するビーム量になる様に、電極の電圧を調整していた。Conventionally, when setting the beam amount in a television camera device, specifically, when setting the first grid (G1) or cathode (K) electrode voltage, it is necessary to image an object that is a light source that corresponds to a beam amount that is greater than or equal to the desired beam amount. Then, while observing the video signal on a waveform monitor, the electrode voltage was adjusted to achieve the desired beam amount.

らの事はテレビジョンカメラの調整時、特に自動調整を
行なう場合の障害となっていた。Therefore, in order to perform this adjustment, it was necessary to have a subject and a light source whose amount of beam was greater than or equal to the amount of beam to be set. These problems have been an obstacle when adjusting the television camera, especially when performing automatic adjustment.

プ、及び７はビーム設定用ボリウムである。FIG. 1 is a diagram for explaining conventional adjustment, in which a subject 1 illuminated by a light source 2 outside the camera is imaged, and the level of the video signal at the preamplifier 6 is measured.
The voltage measurement volume 7 was being adjusted. In the figure, 3 is a lens, 4 is a prism optical system, 5 is an image pickup tube, 6 is a preamplifier, and 7 is a beam setting volume.
本発明の目的は、ビーム量調整時において、カメラ外に
光源等を設けることなくビーム量の調整ができるテレビ
ジョンカメラ装置を提供することである。An object of the present invention is to provide a television camera device that can adjust the beam amount without providing a light source or the like outside the camera.

きる。According to the present invention, since the light source for setting the beam amount is built into the optical system of the television camera, the setting of the beam amount, that is, the adjustment of the electrode voltage at Gl or Gl, is automatically performed using a computer or the like. Thus, a television camera device is obtained which also enables the following functions. In the present invention, there is no need to prepare an object and a light source for beam setting externally, and the beam setting light source built into the lens or optical system is operated according to the beam amount setting control signal to output video. By detecting the level, it is possible to control the beam amount, that is, the electrode voltage of the image pickup tube.

FIG. 2 is a diagram showing an embodiment of the present invention, and compared to FIG. 1, an external subject 1 and light source 2 are not required. Instead, the camera device has a built-in light source 8 for beam setting, and when setting, the lens 3. Light enters through the entire prism optical system 4.
