Abstract
An image pickup apparatus includes an optical system, an image sensor configured to photoelectrically convert an optical image formed by the optical system and to output image data, an infrared cut filter movable between a first position at which the infrared cut filter is inserted into an optical path of the optical system and a second position at which the infrared cut filter is removed from the optical path of the optical system, and a control unit configured to determine, based on the image data, whether or not the infrared cut filter is located at a position different from each of the first position and the second position.
Claims20
An image pickup apparatus comprising:
- an optical system;
- an image sensor configured to photoelectrically convert an optical image formed by the optical system and to output image data;
- an infrared cut filter movable between a first position at which the infrared cut filter is inserted into an optical path of the optical system and a second position at which the infrared cut filter is removed from the optical path of the optical system;
- a hardware processor;
- and
- a memory for storing instructions to be executed by the hardware processor, wherein, when the instructions stored in the memory are executed by the hardware processor, the image pickup apparatus functions as:
- a control unit configured to determine, based on the image data, whether or not the infrared cut filter is located at a position different from each of the first position and the second position.
A control method of an image pickup apparatus including an infrared cut filter movable between a first position at which the infrared cut filter is inserted into an optical path of an optical system and a second position at which the infrared cut filter is removed from the optical path of the optical system, the control method comprising the steps of:
- acquiring image data by photoelectrically converting an optical image formed by the optical system;
- and
- determining, based on the image data, whether or not the infrared cut filter is located at a position different from each of the first position and the second position.
A storage medium storing a program that causes a computer to execute a control method of an image pickup apparatus including an infrared cut filter movable between a first position at which the infrared cut filter is inserted into an optical path of an optical system and a second position at which the infrared cut filter is removed from the optical path of the optical system, the control method comprising the steps of:
- acquiring image data by photoelectrically converting an optical image formed by the optical system;
- and
- determining, based on the image data, whether or not the infrared cut filter is located at a position different from each of the first position and the second position.
