Abstract
The precision of phase difference AF control is raised.An image pickup device includes a color filter that is provided with repeatedly disposed basic array patterns configured with a first array pattern and a second array pattern disposed symmetrically about a point, wherein the first array pattern includes a first filter placed over 2×2 pixels at the top left and a pixel at the bottom right of a 3×3 square array, a second filter placed over a right end pixel of a vertical direction center line of the square array and over a left end pixel a lower edge line, and a third filter placed over a pixel at the right end of the vertical direction upper edge line of the square array and over a center pixel of the lower edge line, and the second array pattern has the same placement of the first filter as that in the first array pattern and has a placement of the second filter and a placement of the third filter swapped over therefrom; and phase difference detection pixels that are placed at positions corresponding to 2 pixels that are adjacent in the horizontal direction out of the 2×2 pixels of at least one side of the upper side or lower side disposed first and second array patterns out of…
