chromatisme (chromatic aberration); chromatic aberration

Optical aberration affecting an optical system and resulting in different propagation according to wavelength. Longitudinal chromatism shifts the depth of focus between each color.

Depth From Defocus (DFD)

Technique for estimating the depth of an object by estimating the defocusing blur affecting its image.

disparity ;disparity

Horizontal offset between two images of the same 3D point taken by two cameras in a rectified stereoscopic configuration.

Point Spread Function (FEP)

Function describing the image of a source point by an optical sensor.
