Abstract: There are provided an image processing apparatus, an image processing method, a program, and a recording medium capable of compatibly achieving a high-accuracy filtering process and reduction in a necessary storage capacity. An image processing apparatus includes a filtering process unit that performs an image filtering process including a plurality of filtering processes. The filtering process unit applies a filter to processing target data to acquire filter application process data, and applies a gain to the filter application process data to acquire gain application process data, in each filtering process. In each filtering process, the gain applied to the filter application process data is acquired based on a “target frequency characteristic of the image filtering process” specified based on an optical characteristic of an optical system used when the original image data is acquired, that is, the optical characteristic according to an imaging condition when the original image data is acquired.

Abstract: An image processing unit 36 includes an information acquisition unit 40, a filter acquisition unit 42, and a filter processing unit 44. The information acquisition unit 40 acquires imaging information of original image data which is acquired by capturing an object image using an optical system. In a case in which the imaging information includes the first imaging condition and does not include the second imaging condition, the filter acquisition unit 42 acquires a sharpening filter which is associated with the first imaging condition and is associated with a representative condition of the second imaging condition. The filter processing unit 44 applies the sharpening filter acquired by the filter acquisition unit 42 to the original image data to acquire sharp image data.

Abstract: An image processing device according to an embodiment of the present invention obtains recovery image data by performing restoration processing using a restoration filter based on a point spread function of an optical system, on original image data obtained from an imaging element by imaging using the optical system. The restoration filter used in this restoration processing (a combination filter and realization filter Fr) is generated by combining multiple base filters Fb. Base filter Fb may be arbitrarily selected from filters that are confirmed beforehand to be effective to prevent image quality degradation.

Abstract: Image data obtained by imaging of an imaging element capable of imaging a subject with sensitivity to a wavelength band of visible light and a wavelength band of near-infrared light via an optical system is acquired. A point image restoration process using a common restoration filter is performed on the image data of the subject captured with sensitivity to the wavelength band of the visible light by the imaging element and the image data of the subject captured with sensitivity to the wavelength band of the near-infrared light by the imaging element. The common restoration filter is calculated on the basis of average optical characteristics of the optical system obtained by performing weighted averaging of first optical characteristics with respect to the visible light of the optical system and second optical characteristics with respect to the near-infrared light of the optical system.

Abstract: An image processing device and an image processing method capable of satisfactorily performing a point image restoration process of a visible light image and a point image restoration process of a near-infrared light image are provided. A point image restoration process is performed on luminance data Y indicating a visible light image and IR data indicating a near-infrared light image using a first point image restoration filter based on a first point spread function with respect to visible light of an optical system and a second point image restoration filter based on a second point spread function with respect to near-infrared light of the optical system. An appropriate point image restoration process is performed on the IR data so that restoration strength (second gain β) in the point image restoration process for the IR data captured with radiation of near-infrared light is higher than restoration strength (first gain α) in the point image restoration process for the luminance data Y.

Abstract: A restoration processing unit performs a restoration process based on an optical transfer function of an optical system for a target image. The entire angle of view of the optical system is greater than 90 degrees. A light amount evaluation region of the optical system is a region in which a distance from the center of an image formation plane is not less than 80% of half of the length of a diagonal line of an imaging surface of an imaging element. When a first evaluation wavelength is used, the ratio of the amount of light in the light amount evaluation region to the amount of light in a region of the optical system corresponding to the center of the image formation plane is not less than 25%. When a second evaluation wavelength is used, the value of the MTF of the optical system acquired at half of the Nyquist frequency of the imaging element is not less than 15%.

Abstract: An imaging lens consists of, in order from the object side, a first lens group fixed during focusing, and a positive second lens group moved toward the object side during focusing from a distant object to a close object. The second lens group consists of, in order from the object side, a first cemented lens consisting of a biconvex lens and a negative lens having a smaller absolute value of curvature radius of the object-side surface than that of the image-side surface, and a second cemented lens as a whole having a positive refractive power and consisting of a negative lens having a smaller absolute value of curvature radius of the image-side surface than that of the object-side surface and a positive lens having a smaller absolute value of curvature radius of the object-side surface than that of the image-side surface. The imaging lens satisfies specific condition expressions.
