  • Publication number: 20170257583
    Abstract: An imaging element of an imaging apparatus includes a plurality of microlenses and a plurality of photoelectric conversion units corresponding to the microlenses. A parallax picture having a parallax is generated by acquiring signals from the plurality of photoelectric conversion units. A CPU performs defective pixel detection by calculating an evaluation value from a first output value which is an output value of a detection pixel and a second output value determined from a pixel adjacent to the pixel and comparing the evaluation value with a predetermined threshold value. The CPU calculates a second evaluation value using the second output value and a first evaluation value derived from the first output value and the second output value and detects the pixel as a defective pixel if the second evaluation value is greater than the threshold value.

  • Patent number: 9621789
    Abstract: An imaging apparatus includes an imaging plane phase-difference type first focus detecting unit and a contrast type second focus detecting unit. A saturation detecting unit detects saturation of focus detecting pixels or imaging pixels provided in an imaging element. A brightness detecting unit detects the brightness of an object. If the number of pixels detected by the saturation detecting unit exceeds a predetermined value or the brightness of an object detected by the brightness detecting unit is less than a predetermined value, a CPU controls a focus adjustment operation only using a first detection amount. Alternatively, the CPU controls a focus adjustment operation based on the result obtained by weighting processing of a first detection amount and a second detection amount in response to an increase in the number of pixels of which saturation of the outputs has been detected or a decrease in the brightness of an object.

  • Patent number: 9521312
    Abstract: Signals of pixels are acquired from an image sensor in which a first pixel, a second pixel, and an imaging pixel are arranged, the first pixel receiving light flux that is restricted to light flux passing through a first portion of a pupil area of an imaging optical system, the second pixel receiving light flux that is restricted to light flux passing through a second portion that is different from the first portion of the pupil area, and the imaging pixel being different from the first and second pixels. Based on the acquired signals, estimated signals at a position at which the first and second pixel is not arranged are estimated. A defocus amount of the imaging optical system is calculated based on evaluation values obtained based on the estimated signals and the signals from the first and second pixels.
