Image element, and imaging device and imaging method using the same for achieving improved image quality regardless of an incident angle of light

摘要

An imaging element which outputs a pair of image signals corresponding to a pair of luminous fluxes which pass through different pupil areas of a photographing optical system, the imaging element includes a first pixel cell group including a plurality of first pixel cells for obtaining the pair of image signals and a second pixel cell group including a plurality of second pixel cells for obtaining the pair of image signals. The first pixel cell includes a first photoelectric converting unit and a first micro lens which is provided above the first photoelectric converting unit. The second pixel cell includes a second photoelectric converting unit and a second micro lens which is provided above the second photoelectric converting unit. The first micro lens and the second micro lens are disposed with different regularities.
