CAC is a function that automatically corrects registration errors mainly caused by slight chromatic aberration, which cannot be
corrected with lenses, and minimizes color weepage on the images.
corrected with lenses, and minimizes color weepage on the images.
Chromatic aberration means magnification ratio chromatic
aberration. Magnification ratio chromatic aberration is
caused by differences in the in red (R), green (G), and blue
(B) refractive indexes of a lens. The lens itself corrects chro-
matic aberration but the astigmatism remains in the sur-
rounding area in particular. The zooming ratio, iris, and focal
distance involves complicated chromatic aberration phenom-
ena in a zoom lens. Images have registration errors.
aberration. Magnification ratio chromatic aberration is

ena in a zoom lens. Images have registration errors.
To correct the chromatic aberration, record the chromatic
aberration characteristics of the lens for the zooming ratio,
iris, and focal distance in the main unit of the camera
recorder and connect a lens suitable for these characteris-
tics. Then perform the correction in accordance with the
zooming ratio, iris, and focus distance of the lens.
The CAC data for the following four kinds of lenses are
stored in the unit at the time of shipment from the factory.
