Abstract
The present technology relates to an endoscope system, an endoscope control method, and a program that allow AF processing to be performed without deterioration in accuracy. Provided are a drive unit that drives a lens, a measurement unit that measures a position of the lens, and a control unit that controls focusing, the control of the focusing including setting a control amount of wobbling at the time of the focusing based on a first hysteresis that is stored and a second hysteresis that is measured upon energization. The present technology is applicable to a medical observation device such as an endoscope or a microscope.
Claims20
An endoscope system comprising:
- a drive assembly that drives a lens;
- a measurement assembly that measures a position of the lens;
- and
- a control circuit that controls focusing, wherein
- the control of the focusing includes setting a control amount of wobbling at a time of the focusing on a basis of a first hysteresis that is stored and a second hysteresis that is measured upon energization.
An endoscope control method of an endoscope system, the endoscope system including a drive assembly that drives a lens, a measurement assembly that measures a position of the lens, and a control circuit that controls focusing, the endoscope control method comprising:
- setting, by the control circuit, a control amount of wobbling at a time of the focusing on a basis of a first hysteresis that is stored and a second hysteresis that is measured upon energization;
- and
- controlling, by the control circuit, the focusing on a basis of the control amount.
A program for causing a computer to perform a process, the computer being configured to control an endoscope system, the endoscope system including
- a drive assembly that drives a lens,
- a measurement assembly that measures a position of the lens, and
- a control circuit that controls focusing, the process comprising:
- setting a control amount of wobbling at a time of the focusing on a basis of a first hysteresis that is stored and a second hysteresis that is measured upon energization;
- and
- controlling the focusing on a basis of the control amount.
