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: 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).
