OPTICAL SYSTEM AND ELECTRONIC DEVICE FOR DEBLURRING

Abstract: an optical system includes a lens assembly comprising a plurality of lenses, and an image sensor configured to sense light passing through the lens assembly, wherein, for a point light source positioned in a central zone of a field of view (fov), a full width at half maximum (fwhm) of a point spread function (psf) of the optical system is greater than an fwhm of a psf of a reference system, wherein the reference system comprises a same number of lenses as the plurality of lenses and another image sensor and is configured to optimize a modulation transfer function (mtf), and wherein, for a point light source positioned in an edge zone of the fov, the fwhm of the psf of the optical system is smaller than the fwhm of the psf of the reference system.
