HDR (High Dynamic Range) Mode (SP-12000M-CXP4 only)
HDR (high dynamic range) mode is a function that uses the exposure time configured with [Exposure
Time] as a base, and allows you to determine input level positions for knee points. You can change the
number of knee points from 1 to 2.
Adjust the [Knee Point 1], [Knee Point 2], [Knee Slope 2], and [Knee Slope 3] settings to configure the
settings.
