Fig.36 Detection area
8.2.4 Balance White Auto
This is a function to enable the auto white balance by using R and B gain controls.
It contains the following methods.
OFF
:
Set the white balance manually
Once
:
Control the auto white balance only one time when it is set
Continuous
:
Continuing control of the auto white balance
AWB Channel area: Can set the area to control the auto white balance.
The detection area is the same as the figure 36.
8.3. LUT
This function can be used to convert the input to the desired output characteristics.
The Look-Up Table (LUT) has 256 points for setup. The output level can be created by
multiplying the gain data by the input level.
8.3.1 LUT Mode
Can be selected from OFF, Gamma or LUT Table.
8.3.2 LUT Index
This represents the “starting” or “input” pixel value to be modified by the Lookup Table. The
SP-20000-PMCL has a 256-point Lookup Table, meaning the index points are treated like an 8bit
image with 0 representing a full black pixel and 255 representing a full white pixel. The index
points are automatically scaled to fit the internal pixel format of the camera. This is common
for all output configuration.
8.3.3 LUT Value
This is the “adjusted” or “output” pixel value for a given LUT index. It has a range of 0 to 4095
(12-bit) and is automatically scaled to the bit depth of the current operating mode (8-bit or 10-
bit).
Note: linear interpolation is used if needed to calculate LUT values between index points. In
the color mode, the LUT function works the same regardless of the color of the pixel.
