Imaging device and an imaging apparatus equipped with this imaging device for imaging a three-dimensional video image and a planar video image

A plurality of pixels 2 are arranged and formed in a square lattice, a color filter RGB is Bayer array, to obtain the first image signal of the phase difference detection pixels 3 and for the left eye acquires a captured image signal for the right eye second discrete pairs in the square lattice and a phase difference detecting pixel 4, provided periodically position, the horizontal and vertical directions of each pixel of a square lattice 2n + 1 (n = 1,2, ... ) the first phase difference detection pixels 3 are provided into individual intervals, the second phase difference detection pixels in the pair with respect to the first phase difference detection pixels 3 in the pixel having the same color of the color filter two pixels away 4 is provided.
