Table 9 shows the relation between the gain parameter and the gain factor values.

3.3.6.1 Black Stretch

The Black Stretch algorithm is used to decrease the black part under the average brightness point.

The inflection point is based on the average brightness, but another value can be set by user. The

range and gain parameters are used to set the correction slope value.

This filter can be used when the overall picture is bright in order to improve the overall contrast.

Figure 18 shows samples of the black stretch algorithm with an average brightness of 128 with

various gain and range values.
