B-16
It is an R, G, B, W color scale pattern that
can move dynamically.
It is an R, G, B, W four circles pattern that
the color order can be changed sequentially.
The pattern is all white (a highlighted pattern
name is located on the upper left corner). It
is for luminance and white balance
adjustment use.
This pattern has five independent, bright
squares for luminance adjustment.
This pattern has five independent, bright
circles for luminance adjustment.
This pattern has three horizontal bars of
different luminance. The central luminance is
all reduced 5% in order to check if the
contrast can be distinguished.
This pattern is for TTL output signal to check
the black and white contrast.
From 0% to 100%, the grayscale raises a
scale every 10% for contrast adjustment.
The middle is black (0%).
The upper part has 16 grayscales from left to
right with brighter scale. The lower part is the
arrangement from right to left.
*Note: The weakest luminance is 60/4095,
and the strongest is 4095/4095. The
difference of every scale is 64/4095.
It is the same as pattern # 47 except it has
32 grayscales.
*Note: The weakest luminance is 28/4095,
and the strongest is 4095/4095. The
difference of every scale is 32/4095.
