Sample Area (Fixed area)
Eight available sample areas are as shown below. Data are continuously sampled within each
area. (See section 5-4-4 “USER1, 2 AREA SET” for USERAREA 1, and 2.)
5-4-2. AVO SETUP
R E S P O N S E : L E V E L 3
RESPONSE
(Filtering
strength)
Sets the filtering strength for calculating
the mean distances that are applied to
histograms created using the sample
data.
The larger the value, the more gradually
filtering is performed, with a more stable
image but slower response.
The smaller the value, the less stable the
image, but with a faster response.
SCENE CUT
*1
(Scene cut
detection)
When set to ON, the cut transitions are
detected and images are properly
adjusted even if there are sharp
luminance changes.
GAMMA MODE
(Gamma
correction)
When set to ON, signal levels are
adjusted using the GAMMA LEVEL
settings. (See section 5-2-3 “GAMMA
LEVEL”.
*1 The following delay will be produced when performing scene cut detection depending on
the input signal format.
Interlaced formats: 2 fields (1 frame) + some lines
Progressive and PsF formats: 2 frames + some lines
Scene cut detection images will be properly adjusted and output when enough frame delay is
set. If the amount of frame delay is insufficient, Scene cut detection will not be properly
processed.
To perform AVO scene cut detection properly, set enough delay using the FRAME DELAY
function. The output delay varies depending on the SYNCRO MODE, input signal format,
FRAME DELAY setting, and video signal H/V phase difference. FRAME DELAY settings are
described on the next page.
