Abstract:
The present invention provides an imaging device capable of capturing a high-quality image by a compact configuration, a signal processing method for the imaging device and a signal processing program for the imaging device. An imaging lens 10A comprises, in order from the object side, a first lens group G1 that is fixed during magnification change, a second lens group G2 and a third lens group G3 that move during magnification change, and a fourth lens group G4 that is fixed during magnification change. The first lens group G1 comprises, in order from the object side, a first-a lens group G1a that is fixed during focusing, a first-b lens group G1b that moves during focusing, and a first lens group rear group G1c that is fixed during focusing. A change in angle of view caused by focusing is corrected by image processing.
