Document Type and Number:
Japanese Patent JP5536698
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress installation space increase and cost increase by allowing existing operation means for instructing a continuous light/dark switching of a diaphragm to also be used as an operation means for switching filters.SOLUTION: Existing direction instruction buttons 86A and 86B for continuously changing the opening diameter of a diaphragm 16 can also be used by mode selection as an operation means for instructing a filter switching of a filter switching mechanism including a plurality of ND filters, visible light cut filters and the like. That is, a diaphragm command generation section 88 becomes operable when a normal mode is selected by a mode selection switch 87, and generates a diaphragm command for continuously increasing and decreasing the opening diameter of the diaphragm 16 during an operation period of the direction instruction buttons 86A and 86B. On the other hand, a filter switching command generation section 89 becomes operable when a special mode is selected by the mode selection switch 87, and generates a filter switching command for sequentially switching the filters every time the direction instruction buttons 86A and 86B are depressed.
