Abstract
Provided are an image processing device, an image processing system, an image processing method, and an imaging optical system group capable of suppressing an increase in costs and appropriately restoring an image. In the imaging optical system, in a case where a first MTF curve Mindicating an MTF value in a first azimuth direction with respect to an amount of defocus from a focal position is compared with a second MTF curve Mindicating an MTF value in a second azimuth direction with respect to the amount of defocus from the focal position, a ratio of a peak value Pof the first MTF curve Mto a peak value Pof the second MTF curve Mis equal to or greater than 2, and a ratio of a half-value width HWof the second MTF curve Mto a half-value width HWof the first MTF curve Mis equal to or greater than 1.25. The restoration filter is a common filter corresponding to a representative value of transfer functions in a plurality of same type imaging optical systems.
