  • Patent number: RE48548
    Abstract: In an image sensor, if a pixel for focusing has a structure having a light-shielding layer for performing pupil division, between the micro lens and the photoelectric conversion unit, the pixel may be configured such that the focal position of the micro lens is positioned further on the micro lens side than the light-shielding layer, and the distance from the focal position of the micro lens to the light-shielding layer is greater than 0 and less than nF?, where n is the refractive index at the focal position of the micro lens, F is the aperture value of the micro lens, and ? is the diffraction limit of the micro lens. This enables variation in the pupil intensity distribution of the pixel for focusing due to positional production tolerance of components to be suppressed.
