  • Patent number: 8823843
    Abstract: An image processing device includes: a detection unit detecting a movement amount of an image between first image data constituting image data generated by an image capturing element provided with a plurality of image generating pixels generating pixel values for generating an image and a plurality of pairs of phase difference detecting pixels generating pixel values for performing focusing determination by phase difference detection, and second image data subsequent to the first image data on a time axis, wherein the movement amount is a movement amount of one phase difference detecting pixel when a defective pixel included in the pair of phase difference detecting pixels is one of the pair; and a correction unit correcting the pixel value of the defective pixel in the second image data on the basis of the detected movement amount and the pixel value of one phase difference detecting pixel in the first image data.

  • Patent number: 8587702
    Abstract: An image processing apparatus includes: an image pickup device with image creating pixels for creating images and pairs of phase difference detection pixels of two types for creating pixel values for in-focus state judgment; a detection unit detecting the edge of a first figure formed by the pixel values of the image creating pixels and the edge of a second figure formed by the pixel values of the pairs of phase difference detection image pixels; and a compensation unit that, if a defective pixel is included in phase difference detection pixels of one type, calculates a distance between the second figure regarding phase difference detection pixels of the other type and the first figure on the basis of the detected edges, and compensates for the pixel value of the defective pixel on the basis of the calculated distance and the pixel values of phase difference detection pixels of another type.
