| 1. A chromatic aberration suppressor circuit for suppressing chromatic aberration which arises in a high-brightness portion
of a subject, the circuit comprising:
detection means for detecting a chromatic aberration portion from an image signal which pertains to the subject and is to
undergo gamma correction;
gamma correction means for subjecting the image signal to gamma correction;
suppression means for suppressing a color component of the chromatic aberration portion, which has been detected by the detection
means, in the image signal after having undergone gamma correction performed by the gamma correction means; and wherein the
detection means detects the chromatic aberration portion on the basis of a G signal among an R signal, a G signal, and a B
signal constituting the image signal that is to undergo gamma correction.
