The imaging device and electronic apparatus

The imaging apparatus 200 includes a aberration control optical system 210 and imaging device 220 having the aberration control function of generating an aberration intentionally, the image processing apparatus 240 for forming the first order image to a high definition final image. Aberration control optical system 210A includes an aberration control element having an aberration control function of generating an aberration intentionally, or by using an aberration control optical system containing the aberration control surface having an aberration control function 2 pixels or more PSF as span, it is formed as a depth extension optical system MTF characteristics with respect to defocus in primary image plane shift region not false resolution at a predetermined frequency has two or more peaks. It is found, it can simplify the optical system, that the cost can be reduced as well, even without performing the image restoration processing can be depth extension, to obtain a small good images influence of appropriate quality of the noise it is possible.
