Imaging apparatus and image correction method

An imaging optical system (11) forms an image of an object on an imaging device (16). An image processing unit (12) generates image data based on an output signal from the imaging device (16), corrects the image data, and outputs corrected image data. An optical filter (13) arranged between the imag...

More Information
Summary:An imaging optical system (11) forms an image of an object on an imaging device (16). An image processing unit (12) generates image data based on an output signal from the imaging device (16), corrects the image data, and outputs corrected image data. An optical filter (13) arranged between the imaging optical system (11) and the image processing unit (12) is structured such that an upper limit of a transmitting wavelength decreases as a distance from an optical axis of the imaging optical system (11) increases on an imaging plane of the imaging device (16) so that a light in an infrared region is transmitted on the optical axis and cut off at a position farthest away from the optical axis on the imaging plane. The image processing unit (12) corrects the image data based on a correction equation corresponding to the upper limit of the transmitting wavelength.
