    • A technology of a phase-difference detecting image pickup element that can precisely detect a focus by a phase difference detection method and that can be properly produced even if pixels are becoming finer is provided. An image pickup element of an image pickup device includes an AF pixel pair 11f performing a pupil division function by receiving an object light beam transmitted through a pair of portions Qa, Qb in an exit pupil; and ordinary pixels that are not provided with the pupil division function. The AF pixel pair 11f includes a pair of photoelectric converters PD having the same size as photoelectric converters of the ordinary pixels and being disposed adjacent to each other in a horizontal direction. A light-intercepting section LS and one microlens ML are provided above the pair of photoelectric converters PD. The light-intercepting section LS has two light-intercepting areas Ea, Eb that intercept the light beam transmitted through the exit pupil. The one microlens ML is interposed between the two light-intercepting areas Ea, Eb. This makes it possible to realize an image pickup element that can precisely detect a focus by the phase difference detection method and that can be properly produced even if pixels are becoming finer.
    • 提供了一种相位差检测图像拾取元件的技术,其可以通过相位差检测方法精确地检测焦点,并且即使像素变得更细,也可以适当地产生。 图像拾取装置的图像拾取元件包括通过接收通过出射光瞳中的一对部分Qa,Qb传输的物体光束来执行光瞳分割功能的AF像素对11f; 以及不具备光瞳分割功能的普通像素。 AF像素对11f包括与普通像素的光电转换器相同尺寸的一对光电转换器PD,并且在水平方向上彼此相邻地布置。 在一对光电转换器PD的上方设置有遮光部LS和一个微透镜ML。 遮光部LS具有遮断通过出射光瞳传播的光束的两个遮光区域Ea,Eb。 一个微透镜ML置于两个遮光区域Ea,Eb之间。 这使得可以实现能够通过相位差检测方法精确地检测焦点的图像拾取元件,并且即使像素变得更细,也可以适当地产生。

    • An imaging device includes an image pickup device having an arrangement of photoelectric converting units, the arrangement in which a plurality of pairs of photoelectric converting units are arranged along a predetermined direction, each pair of photoelectric converting units receiving light beams of a subject passing through partial areas in a pair that are lopsided in reverse to each other along the predetermined direction in an exit pupil of a shooting optical system, and a focus detector for performing focus detection of a phase-difference detecting technique according to data obtained from the pair of photoelectric converting units in the arrangement of the photoelectric converting units. The focus detector corrects the data according to a correction amount corresponding to a positional shift amount from the normalized position, and performs focus detection of the phase-difference detecting technique according to the corrected data.
