  • Publication number: 20220130879
    Abstract: The purpose of the present disclosure is to improve the dynamic range of an image sensor including a polarization pixel. The image sensor includes: a high-sensitivity pixel group; and a low-sensitivity pixel group. The high-sensitivity pixel group included in the image sensor includes a plurality of high-sensitivity pixels. The low-sensitivity pixel group included in the image sensor includes a plurality of low-sensitivity pixels. A polarization unit that causes incident light in a predetermined polarization direction to be transmitted therethrough is disposed in part of pixels of at least the high-sensitivity pixel group, of the high-sensitivity pixel group and the low-sensitivity pixel group.

  • Patent number: 10088608
    Abstract: The present technology relates to a lens array and a manufacturing method therefor, a solid-state imaging apparatus, and an electronic apparatus that can improve the AF performance while suppressing the deterioration of image quality. A lens array includes microlenses that are formed corresponding to phase difference detection pixels that are provided to be mixed in imaging pixels. Each of the microlenses is formed such that a lens surface thereof is a substantially spherical surface, the microlens has a rectangular shape in a planar view and four corners are not substantially rounded, and a bottom surface in vicinity of an opposite-side boundary portion that includes an opposite-side center portion of a pixel boundary portion in a cross-sectional view is higher than a bottom surface in vicinity of a diagonal boundary portion that includes a diagonal boundary portion. The present technology is applicable to a lens array of a CMOS image sensor, for example.
