Title:
LENS OPERATION DEVICE
Document Type and Number:
Japanese Patent JP2021036253
Kind Code:
A
Abstract:
To solve the problem in which: in a lens device having movable optical members including a zoom lens, a focus lens, and an iris, and a lens operation device, when the lenses are replaced, positions indicated in a command value at a specific position of an operation member are different for each of the attached lenses; when the lenses are changed, the relationship between the specific position of the operation member and the positions indicated by the command value is broken down; thus, an arbitrary position of the operation member cannot be determined as a desired command position.SOLUTION: An operation device has an operation unit that can be rotatably operated, an operation position detection unit that detects the position of the operation unit and outputs a position signal, a command value calculation unit that calculates a drive command value of a lens device, and a communication unit that communicates with the lens device, and the operation device has a setting unit that can set at least one or more command values corresponding to an arbitrary position of the operation unit. The drive command value calculation unit calculates continuously changed command values based on setting information set by the setting unit and a signal detected by a position detection unit.SELECTED DRAWING: Figure 1
