Abstract: An information processing system includes a processor. The trained model is trained to resolution recover a low resolution training image generated by low resolution processing performed on a high resolution training image to a high resolution training image that represents a high resolution image captured with a predetermined object through the first imaging system. The low resolution processing represents processing that generates a low resolution image as if captured with the predetermined object through the second imaging system and processing that simulates the second imaging method, and includes processing that simulates a resolution characteristic of an optical system of the second imaging system. The processor uses the trained model to resolution recover the processing target image captured through a second imaging system to an image having a resolution at which the first imaging system performs imaging.

Abstract: The color filter array 21a comprises seven or more types of color filters including a first color filter. The seven or more types color filters have different spectral sensitivity characteristics. The seven or more types of color filters are arranged in a two-dimensional form. Among the seven or more types of color filters, at least two types of color filters are designated as a color filter of interest. Two color filters arranged at a first interval on both sides of the color filter of interest along a first direction are of the same type. Two color filters arranged at a second interval on both sides of the color filter of interest along a second direction that is different from the first direction are of the same type. Among the color filters, at least one type of color filter have a density higher than that of the other types of color filters, thereby realizing acquisition of highly accurate gradient information from a multiband color filter array.

Abstract: An image processing unit has an image acquisition part, a correlation determination part, a reference image generation part, and an interpolation image generation part. The image acquisition part acquires an original image. The correlation determination unit determines whether the correlation of an image component of a primary reference band with image components of respective bands other than the primary reference band is either high correlation or low correlation. The reference image generation part interpolates missing pixels in the image component of the primary reference band by switching the interpolation method based on the correlation determination result obtained by the correlation determination part. The interpolation image generation part interpolates, using the correlation determination result and the primary reference image, missing pixels in at least some of the image component of the primary reference band.
