(10)3-D White Shading Correction
The camera picture area is divided into up to 1000
separate zones, each of which may have different
shading value. The correction is automatically
interpolated across adjacent zones. This technique
provides precise white shading correction over the
whole picture area. The 3D shading mode can be
enabled through the camera maintenance menu, and
operates automatically each time white shading is
performed. Because the camera 'learns' and
interpolates the data the accuracy may be improved
still further on subsequent auto shading operations.
White shading data should be stored in the camera
OHB file or will otherwise be lost when the camera
power is turned off.

(11)Fine Detail
The Fine Detail function allows the width of the detail
edge to be adjusted without changing the peak level.*

(12)Cross Colour Suppression
Separating the luminance and chrominance
components of a composite signal can be a difficult
task, even with the most advanced comb filtering
techniques. In order to keep cross colour and cross
luminance to a minimum, the BVP-E10 Series virtually
eliminates frequency components that may result in
such artifacts being generated prior to the signal
output. These frequency components are eliminated

from the Y/R-Y/B-Y signals within the camera head by
using sophisticated digital three line (NTSC)/five line
(PAL)* comb filtering. This results in more greatly
reduced cross colour and dot crawl than normally
seen on a picture monitor fed from a composite video
signal.
