Patent ID: 11887282
Assignee: SK HYNIX INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 3:
4. The noise removing circuit of claim 1, wherein the noise coring strength is expressed according to the following equation:

coring strengthlow=(Log(Y)−Log(Lowth))/(Log(Lowth+coring_width)−Log(Lowth))

coring strengthsat=(Log(Y)−Log(Satth))/(Log(Satth+coring_width)−Log(Satth)),

where ‘coring strengthlow’ represents the coring strength of the first region, ‘coring strengthsat’ represents the coring strength of the second region, ‘Log’ represents a log domain conversion function, ‘Lowth’ represents the low threshold, ‘Satth’ represents the saturation threshold and ‘coring_width’ represents the coring width parameter.
