Color imaging element, imaging device, and storage medium storing an imaging program

A color image pickup device comprising:

• an image pickup device comprising a plurality of photoelectric conversion elements arrayed in a horizontal direction and a vertical direction;
• a color filter that is provided above a plurality of pixels configured by the plurality of photoelectric conversion elements, the color filter having repeatedly disposed 6×6 pixel basic array patterns configured with a first array pattern and a second array pattern disposed symmetrically about a point, wherein the first array pattern has a first filter corresponding to a first color that contributes most to obtaining a brightness signal placed at the 4 corner and center pixels of a 3×3 pixel square array, a second filter corresponding to a second color different from the first color placed in a line at the horizontal direction center of the square array, and a third filter corresponding to a third color different from the first color and the second color placed in a line at the vertical direction center of the square array, and the second array pattern has the same placement of the first filter as that in the first array pattern and has the placement of the second filter and the placement of the third filter swapped over to that of the first array pattern;
• and
• phase difference detection pixels placed at least at positions corresponding to the first filter at a top edge side and a bottom edge side in the basic array pattern.
