Abstract: Color filters are used for color images obtained using imaging devices such as conventional image sensors. Imaging elements with color filters are sold, and an appropriate combination of the imaging element and a lens or the like is incorporated in an electronic device. Only providing a color filter to overlap a light-receiving region of an image sensor reduces the amount of light reaching the light-receiving region. An imaging system of the present invention includes a solid-state imaging element without a color filter, a storage device, and a learning device. Since the color filter is not included, colorization is performed on obtained monochrome image data (analog data), and coloring is performed using an AI system.

Abstract: Color filters are used for color images obtained using imaging devices such as conventional image sensors. Imaging elements with color filters are sold, and an appropriate combination of the imaging element and a lens or the like is incorporated in an electronic device.

An imaging system of the present invention includes a solid-state imaging element without a color filter, a storage device, and a learning device. As a selection standard for reducing the amount of learning data, in an HSV color space, saturation is used, and selection is performed so that the saturation has optimal distribution. When colorization disclosed in this specification is performed, the colorization and object highlight processing can be performed at the same time.
