Abstract
A control section outputs a control signal. An actuator is connected to a drive section and operates based on the control signal. An operation information acquisition section acquires operation information related to an operation status of the actuator. A storage section stores correction information included in control information which includes a relationship between an operation status and the control signal. The correction section determines whether or not the control signal and the operation status are consistent with the control information, and when inconsistent, corrects correction information for consistency.
Claims10
An endoscopic system comprising:
- an endoscope comprising an insertion section;
- at least one control circuit configured to output a control signal, wherein the control signal is a one-line output using one terminal of the at least one control circuit;
- a drive circuit comprising:
- a first terminal configured to output a first potential which is higher than a ground potential based on the control signal;
- and
- a second terminal configured to output a second potential which is higher than the ground potential based on the control signal;
- an actuator connected between the first terminal and the second terminal, wherein the actuator is configured to be operable in a positive direction and a negative direction in accordance with a potential difference between the first potential and the second potential;
- a spiral provided on the insertion section, wherein the spiral is configured to be driven by the actuator in order to advance and retreat the insertion section;
- and
- a memory,
- wherein the at least one control circuit is configured to store operation information related to an operation status of the actuator,
- wherein the memory is a configured to store correction information included in control information which includes a relationship between the operation status and the control signal for obtaining the operation status, and
- wherein the at least one control circuit is configured to:
- determine whether or not the control signal and the operation status obtained based on the operation information are consistent with the control information;
- and
- in response to determining that the control signal and the operation status obtained based on the operation information are inconsistent, perform correction with respect to the correction information for consistency.
