Abstract: Provided are a lens device, an imaging apparatus, and a filter unit capable of suppressing occurrence of ghosts and flares. The lens device includes a first optical filter and a second optical filter in order from an object side in an optical path. The first optical filter is composed of an optical filter (for example, a band-pass filter) that has a light transmission band in a specific wavelength region. The second optical filter is composed of an optical filter (band-stop filter) that has a light absorption band in a wavelength region which is different from the light transmission band of the first optical filter.

Abstract: A data processing apparatus, a method, a program, and a multispectral camera that can favorably remove an interference component and reduce noise included in a plurality of images output from an image sensor of a multispectral camera are provided. In a data processing method, first captured data that corresponds to a plurality of wavelength ranges output from an image sensor of a multispectral camera and that includes first noise is processed. In the data processing method, an interference removing parameter for removing an interference component included in the first captured data is acquired (step S30), and the interference component included in the first captured data is removed based on the interference removing parameter (step S40). Then, noise reducing processing of reducing second noise included in second captured data after interference removing is performed (step S60).

Abstract: Provided are an imaging apparatus and a method capable of capturing a high-quality multi spectral image. The imaging apparatus includes: an optical system that has three or more aperture regions at a pupil position or near the pupil position, each of the aperture regions being provided with a different combination of a polarizing filter and a bandpass filter such that the aperture region transmits light having a combination of a different polarization angle and a different wavelength range; an image sensor in which three or more types of pixels that receive light having different polarization angles are arranged two-dimensionally; and a processor that performs interference removal processing on a signal output from the image sensor and generates an image signal for each of the aperture regions. In a case where the optical system has three or more types of the polarizing filters and the polarizing filters are arranged in an order of the polarization angles, at least one of differences in the polarization angles of the adjacent polarizing filters is different from the others.
