Abstract
A lens device includes a zoom lens; a focus lens; a detection unit that directly detects a position of the zoom lens; and a control unit that maintains a parameter for performing drive control of the focus lens in a case where a movement amount of the zoom lens based on a detection result of the detection unit is less than a predetermined threshold, switches the parameter in a case where the movement amount of the zoom lens is equal to or greater than the threshold, and performs drive control of the focus lens on the basis of the maintained or switched parameter.
Claims11
A lens device comprising:
- a zoom lens;
- a focus lens;
- a detection unit that directly detects a position of the zoom lens;
- and
- a control unit that maintains a parameter for performing drive control of the focus lens in a case where a movement amount of the zoom lens based on a detection result of the detection unit is less than a predetermined threshold, switches the parameter in a case where the movement amount of the zoom lens is equal to or greater than the threshold, and performs drive control of the focus lens on a basis of the maintained or switched parameter.
A control method comprising:
- maintaining a parameter for performing drive control of a focus lens in a case where a movement amount of a zoom lens based on a detection result of a detection unit that directly detects a position of the zoom lens is less than a predetermined threshold;
- switching the parameter in a case where the movement amount of the zoom lens is equal to or greater than the threshold;
- and performing drive control of the focus lens on a basis of the maintained or switched parameter.
An imaging system comprising a lens device and an imaging device, wherein
- the lens device includes:
- a zoom lens,
- a focus lens,
- a detection unit that directly detects a position of the zoom lens, and
- a control unit that maintains a parameter for performing drive control of the focus lens in a case where a movement amount of the zoom lens based on a detection result of the detection unit is less than a predetermined threshold, switches the parameter in a case where the movement amount of the zoom lens is equal to or greater than the threshold, and performs drive control of the focus lens on a basis of the maintained or switched parameter, and
- the imaging device includes
- an imaging element that captures a subject image incident via the lens device.
