Japanese Patent JP7271353
Kind Code:
B2
Abstract:
An image pickup apparatus includes an image sensor that photoelectrically converts an object image formed by an image pickup optical system including a zoom lens and a focus lens, a data storage that stores focus data indicating an in-focus position of the focus lens according to an object distance and a position of the zoom lens, and a wavelength acquirer that acquires a wavelength of imaging light incident on the image sensor. The focus data includes data for visible light and data according to a wavelength of infrared light. The wavelength acquirer acquires includes the wavelength of the imaging light using the focus data, the object distance, the position of the zoom lens, and a position of the focus lens when the image pickup optical system is in focus in a state where the visible light and the infrared light can enter the image sensor.
