  • Patent number: 10942304
    Abstract: The present technology relates to a solid-state imaging element, a manufacturing method of the same, and an electronic device that achieve the extension of a dynamic range by making a difference in light-receiving sensitivity between low-sensitivity pixels and high-sensitivity pixels without changing spectral characteristics. The solid-state imaging element includes a pixel array portion in which two kinds of pixels different in light-receiving sensitivity, high-sensitivity pixels and low-sensitivity pixels are arrayed. The low-sensitivity pixels have a gray filter on or under a color filter to decrease light transmission factor in a visible-light region by a predetermined ratio. The present technology is applicable to solid-state imaging elements and the like, for example.
