Document Type and Number:
Japanese Patent JP2023071021
Kind Code:
A
Abstract:
To provide a small-sized imaging device with low power consumption, capable of detecting an abnormality in the insertion/removal state of an infrared cut filter.SOLUTION: An imaging device (100) includes an optical system (210), an imaging device (240) that photoelectrically converts an optical image formed by the optical system and outputs image data, an infrared cut filter (320), a filter holder (310) that includes a frame portion (312) and holds an infrared cut filter, a drive unit (340) that drives the filter holder such that the infrared cut filter can be inserted into and removed from an imaging optical path, and a control unit (501) that determines whether the insertion/removal state of the infrared cut filter is abnormal on the basis of the image data.SELECTED DRAWING: Figure 2
