Document Type and Number:
Japanese Patent JP6874204
Kind Code:
B2
Abstract:
Provided are a stop control device, a stop control method, a stop control program, an exposure control device, an exposure control method, an exposure control program, an interchangeable lens, a camera main body, and a camera capable of setting accurately a target opening diameter in a short time. In a case where a stop is set to the target opening diameter, a driving stop position of a stop motor at which an opening diameter reaches the target opening diameter in a case where the stop motor is driven at a first speed is A, and a variation width of the opening diameter caused in a case where the opening diameter reaches the target opening diameter by driving the stop motor (36) at a second speed faster than the first speed is X. The driving stop position of the stop motor is A, and the stop motor is driven at a first speed in a section from the start of driving to a position P is driven at the second speed, and the stop motor is driven at the first speed in a section after the position P. The position P is set to a position of (A−X/2).
