Control apparatus, image capturing apparatus, and control method

A control apparatus comprising:

• a data acquirer configured to acquire correction data indicating a relationship between a temperature difference between a temperature detected by a temperature detector and a reference temperature, and a focus movement amount;
• and
• a focus controller configured to perform focus correction based on the temperature difference and the correction data to perform focus control,
• wherein the focus controller is configured to change the focus correction depending on a state of a setting changer that changes a setting of a function of an image capturing apparatus.

An image capturing apparatus comprising:

• an image sensor configured to photoelectrically convert an optical image formed via an image capturing optical system;
• a temperature detector configured to detect a temperature;
• a data acquirer configured to acquire correction data indicating a relationship between a temperature difference between a temperature detected by the temperature detector and a reference temperature, and a focus movement amount;
• a focus controller configured to perform focus correction based on the temperature difference and the correction data to perform focus control;
• and
• a temperature changer configured to change a temperature,
• wherein the focus controller is configured to change the focus correction depending on a drive state of the temperature changer.

A control method comprising the steps of:

• acquiring correction data indicating a relationship between a temperature difference between a temperature detected by a temperature detector and a reference temperature, and a focus movement amount;
• and
• performing focus correction based on the temperature difference and the correction data to perform focus control,
• wherein the step of performing the focus control includes changing the focus correction depending on a drive state of a temperature changer that changes a temperature.
