Optical Enhancement (Oe) - Pentax EPK-i7010 Instructions For Use Manual

Optical Enhancement (OE)

This video processor is equipped with two optical filters placed inside Xenon lamp light path to provide optical enhancement
(OE), which combines the band limited light and the digital processing.
PENTAX OE technology has two modes, OE Mode1, 2.
OE Mode1 uses a spectral filter that transmits band limited green and blue light and is intended to provide the user with
enhanced image of blood vessels and fine structure of mucosa.
OE Mode2 uses a different spectral filter that transmits band limited red, green and blue light and is intended to provide the
user with enhanced image of blood vessels and fine structure of mucosa in an image closer to white light image.
NOTE
OE mode cannot be processed simultaneously with [SE], [CE], [TE].
WARNING
 If any newly identified irregularities in the endoscopic image are observed during any of the image enhancement
observational modes, immediately return to the normal white light observation mode.
 Do not rely on the image enhancement observational modes alone for primary detection of lesions or for decisions
regarding any potential diagnostic or therapeutic intervention.

Setting Value Explanation
Off, Mode1, Mode2 Inserts one of two optical filters corresponding to Mode1
and Mode2 into the illumination light path to provide a
band-limited spectrum. The band-limited spectrum
enhances blood vessels and fine structure of mucosa.
Off, +1, +2, +3, +4, Enhances the sharpness of edges and emphasizes the
+5, +6, +1/a1, +2/a2, mucosal structures (the enhancement level is increased
+3/a3, +4/a4, +5/a5, with the setting value).
+6/a6
-5, -4, -3, -2, -1, 0, +1, Allows for adjustment of brightness of image (a larger value
increases brightness).
+2, +3, +4, +5
Average, Peak Allows for adjustment of brightness level with respect to
an averaging of the brightness of the video signal or with
respect to the peak brightness of the screen.
-5, -4, -3, -2, -1, 0, +1, Allows for adjustment of red and blue tone (a larger value
+2, +3, +4, +5
increases red or blue color intensity).
Off, Low, Medium, Allows for correction of noise appearing by image
High
processing.
