Abstract: The present disclosure relates to detection of crosstalk included in images output from an image sensor. An information processing apparatus includes a processor configured to process images output from an image sensor of an imaging apparatus that captures images having different characteristics by splitting a pupil. The processor is configured to acquire a first image that is captured by the imaging apparatus under a first imaging condition and that is output from the image sensor, acquire a second image that is captured by the imaging apparatus under a second imaging condition different from the first imaging condition and that has the same characteristic as the first image among the images output from the image sensor, and detect crosstalk included in the images based on a correlation between feature amounts of the first image and the second image.

Abstract: An optical system has the entire angle of view at a wide-angle end of not smaller than 90 degrees. A spatial frequency at which an MTF of the optical system acquired using an evaluation wavelength in a region of an image formation plane in which the distance from the center of the image formation plane is not less than 80% and less than 95% of half of the length of a diagonal line of an imaging surface of an imaging element image is not more than 30% is higher at the wide-angle end than at a telephoto end. When F≧√(Fw×Ft) is satisfied (where F indicates the focal length of the optical system when the target image is captured, Fw indicates the focal length at the wide-angle end, and Ft indicates the focal length at the telephoto end), a sharpening processing unit performs a restoration process based on an optical transfer function of the optical system as a sharpening process.

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: The imaging lens consists of, in order from an object side, a negative first lens group immovable during focusing, a stop and a positive second lens group moving during focusing. The first lens group consists of, in order from the object side, a meniscus lens having a convex surface toward the object side, a negative meniscus lens having a convex surface toward the object side, a negative lens, a biconvex lens, a negative meniscus lens having a convex surface toward the object side, and a positive lens having a convex surface toward the object side. Predetermined conditional expressions concerning a focal length f of the entire system, a focal length f1 of the first lens group, and a shape of an air lens between first and second lenses of the first lens group from an image side are satisfied.

Abstract: The imaging lens consists of, in order from the object side, a first lens group, an aperture stop, a second lens group having a positive refractive power. During focusing from a distant object to a close-range object, the first lens group remains stationary, and the aperture stop and the second lens group integrally move to the object side. The imaging lens satisfies predetermined conditional expressions relating to a focal length of the whole system, a focal length of the first lens group, a principal point position of the second lens group, a focal length of the second lens group, a back focal length, and the like.

Abstract: For causing a near-infrared light image obtained through imaging in a second imaging mode to be easily viewed while suppressing an increase in size and number of components, in a case where an imaging unit is operating in the second imaging mode, a change region where there is a change is detected through comparison with the second image data that the imaging unit has acquired before the second image data, from within the second image data acquired by the imaging unit. Combination image data obtained by combining the change region image data corresponding to the change region within the second image data with background image data of a color image generated on the basis of first image data acquired in a first imaging mode immediately before the second imaging mode by the imaging unit and corresponding to a background region different from the change region within the second image data is generated on the basis of the detection result of the change region.
