Description

第４の発明に係る光学機器は、上記第１の発明において、上記制御部は、外部からの上記絞り部の開口量に関する指示を入力することが可能であって、上記記憶部の出力と上記ズームレンズ群の位置に応じて上記絞り部の開口量を設定する動作を行っている状態で、上記外部からの指示が入力された場合に、上記外部からの指示が入力された時の上記ズームレンズ群の位置に応じて、上記記憶部の出力に基づき上記絞り部の開口量を設定し、上記絞り部の開口量の設定が完了した時の上記ズームレンズ群の位置に応じて上記絞り部の開口量を設定し直す。
第５の発明に係る光学機器は、上記第１の発明において、上記制御部は、外部からの上記絞り部の開口量に関する指示を入力することが可能であって、上記外部からの上記絞り部の開口量に関する指示を入力すると、上記指示の開口量を上記記憶部に記憶させるとともに、上記外部から入力された上記絞り部の開口量に関する指示に基づいて上記絞り部の開口量を設定し、上記指示に基づいて開口量を設定している状態で、上記ズームレンズ群の位置の変化を検出すると、上記ズームレンズ群の位置と上記記憶部に記憶された指示の開口量に応じて上記絞り部の開口量を設定する際の目標位置を更新する。

According to a fourth aspect of the present invention, in the optical device according to the first aspect, the control unit can input an instruction regarding an opening amount of the diaphragm from the outside, and the output of the storage unit and the above The zoom when the instruction from the outside is inputted when the instruction from the outside is inputted in the state of performing the operation of setting the aperture amount of the diaphragm according to the position of the zoom lens group According to the position of the lens group, the aperture amount of the diaphragm unit is set based on the output of the storage unit, and the aperture unit according to the position of the zoom lens group when the setting of the aperture amount of the diaphragm unit is completed Reset the opening amount of.
According to a fifth aspect of the present invention, in the optical device according to the first aspect, the control unit can input an instruction regarding an opening amount of the diaphragm unit from outside, and the diaphragm unit from the outside. When the instruction regarding the opening amount is input, the opening amount of the instruction is stored in the storage unit, and the opening amount of the diaphragm portion is set based on the instruction regarding the opening amount of the diaphragm portion input from the outside. When a change in the position of the zoom lens group is detected in a state where the opening amount is set based on the instruction, the aperture is set according to the position of the zoom lens group and the opening amount of the instruction stored in the storage unit. The target position when the opening amount of the part is set is updated.
