3. Expressing the gradation of a picture (Knee, Gamma)
3-1. Knee adjustment
Due to the sunny weather or the lighting, “blown-out highlights” sometimes occur, where bright areas look completely
white.
This is a phenomenon caused by the luminance signals that are out of the camera’s Dynamic Range (processing
range). In order to put such high-brightness input signals within the Dynamic Range, Knee function can be used to
compress the gradation. However, the color gradation is also compressed at the same time by this function. So,
depending on the scene, the color may become lighter. In that case, setting [KNEE MASTER SLOPE Rch] and
[KNEE MASTER SLOPE Bch] will enable the adjustment of color.
