Abstract
A digital signal processing apparatus includes a digital coring circuit removing samples of digital input signals in a range determined by a digital threshold level signal. The threshold level signal developed by a coring control device is controllable according to the results of comparing at least a portion of the digital input signals to a digital reference level. In a television receiver having digital signal processing circuitry, for example, the coring range is decreased as the luminance signal level increases towards a brighter picture level and is increased as the luminance signal level decreases towards a darker picture level.
