Dynamic Gamma; Burn-In Image Reducer - JVC PD-42V475 Service Manual

Picture Adjust

Dynamic Gamma

JVC's Dynamic Gamma Circuitry (DGC) makes it easier to see dark areas when a picture
has many dark areas, and makes it easier to see the bright areas when a picture has many
bright areas. DGC is turned on, DGC analyzes and adjusts the total level of picture brightness
balance, especially in dark areas where the level of greyscale is often lost, turning completely
to black. DGC automatically enhances the detail in these dark areas providing a more dynamic
image with fi ner detail, so the optimum picture settings are automatically set for each picture.
Normally use with DGC on.
