Claim 14:
15. An imaging apparatus, comprising:
a pixel array unit including a plurality of pixel groups, the plurality of pixel groups including i) normal pixel groups including only normal pixels, and ii) mixed pixel groups including at least one normal pixel and a first phase difference detection pixel that is partially shielded from incident light,
wherein, for each normal pixel group, color filters of the normal pixels transmit a same wavelength of light,
wherein, for each mixed pixel group, the first phase difference detection pixel has a single corresponding on-chip lens,
wherein each pixel group includes four pixels arranged in a 2×2 array,
wherein each mixed pixel group includes a second phase difference detection pixel that is partially shielded from incident light,
wherein, for each mixed pixel group, the first phase difference detection pixel and the second phase difference detection pixel are diagonal to one another and have a same exposure time period, and
wherein, for each mixed pixel group, the first and second phase difference detection pixels are partially shielded on left areas or right areas as viewed from a light incident side.
