Meaning of APERTURE CORRECTION in English

APERTURE CORRECTION

As applied to a video signal, this is frequency peaking, usually at just one frequency, to compensate for loss of picture detail. Aperture correction is applied in the video camera. The sharpness control, in the display device, serves a similar frequency compensation function. There are times when the terms "sharpness" and "aperture correction" are used interchangeably. See VE T14 C1-5.
