Abstract Translated from Japanese (57)【要約】 【目的】（ａ）被写体からの光の集光率が高く比較的光 源のパワーが小さくてすみ、（ｂ）解像度を損なわずに 観察対象物に挿入するケーブルの径も小さくできるもビ デオカメラの解像度がよく、（ｃ）かつ光源の光量の調 節も自動的に得られ作業効率を向上し得る上に、（ｄ） 色再現性をも良好に保つようにする。 【構成】光源３１からの照明光は、光補正フィルタ３６ を有した自動絞り装置３３及び光伝送路１２を介して被 写体１１内部を照明する。撮像素子１４には、被写体１ １からの光学像が補正フィルタ１７を通して結像され、 撮像信号は信号伝送路１６を通して信号処理回路２２に 導かれる。 (57) [Abstract] [Purpose] (a) The light collection rate from the subject is high, and the power of the light source is relatively small. (B) The diameter of the cable to be inserted into the observation target without impairing the resolution. Although it can be made smaller, the resolution of the video camera is good, and (c) and the adjustment of the light amount of the light source can be automatically obtained to improve work efficiency, and (d). Try to keep good color reproducibility. [Structure] Illumination light from a light source 31 is emitted from a light correction filter 36. The inside of the subject 11 is illuminated through the automatic diaphragm device 33 having the above and the optical transmission path 12. The image sensor 14 includes a subject 1 The optical image from 1 is formed through the correction filter 17, The image pickup signal is guided to the signal processing circuit 22 through the signal transmission line 16.
