AGC
Keeps video signal increased to +6 or 12 dB
compared With the standard level when AGC
ON. AGC ON/OFF & AGC level is set internally.
The video signal for sampling is detected within
the area of a square at the image center (AREA
detection) or in two small areas located on the
image (DIVISION detection).The area size of
the AREA detection can be adjusted to 10, 20,
30, 40 & 50% of the image height internally. The
area is displayed on the monitor when adjusting
the size. The area size of the DIVISION
detection is fixed. The signal detection in case
of the AREA detection is of peak detection or
average detection selectable internally. The
signal detection in case of the DIVISION
detection is of weighted average detection.
Gamma (r)
0.45 & normal gain.
Black / white reversal
Outputs LIVE image in negative when the
function is ON or during external ON signal
input when the function is in EXT mode. The
function ON/Ext is selectable internally.
Shading correction
SAWtooth and PARAbolic for both H and V.
Correctable more than + 0.2V under
γ
; 0.45 and
normal gain.
Circle blanking
Diameter is adjustable from 90% of useful
image screen height to useful image screen
width (133% of useful image screen height).
Noise reduction(NR)
Recursive filter with motion detection for
reduction of X-ray quantum noise.
K constant
Any one of 4 preset constants with independent
motion detection level can be selected by
external control. The factory preset constants
are 2,4,8 & 16 with motion detection level of
Medium respectively. In case no external
selection is input, the other internally preset
constant works. The factory preset constant for
this is 3 with motion detection levels of Medium
also. These % constants can be changed
internally to the desired values chosen from
1,1.5,2,3,4,8,10,12,14,16,24 and 32 with motion
detection level selected from 4 steps
respectively.
