3. KEY FEATURES
■DynaLatitudeTM Function
• The DynaLatitude function processing enables you to adjust the contrast of each pixel according to
the luminance signal level of each picture element.
• The DynaLatitude function minimizes video level distortion based on video signal histograms in
order to utilize the limited dynamic range of the standard video signal.
• If there is a dark section and bright section in one image (i.e. shade and sunshine), then both parts
will often look vague. The DynaLatitude function allows you to adjust the sharpness of both
sections.
• Even when lighting is favorable, more luminance levels will be allocated to the subject, creating a
clearer, more detailed image.

■DCC+ Process
•The DCC+ (Dynamic Contrast Control Plus) manages video signal data at three levels - brightness,
hue and saturation. The result is an image with suitable knee correction and without hue distortion.

■Knee and Black Stretch
•By adjusting the knee, a knee point and knee slope are set so that the highlighted areas of the picture
can be clearly reproduced.
•Contrast in the dark area of the image can be variably adjusted using the Black Stretch function for
a clear view of specific details.
■Pedestal
•Black or dark parts of the picture can be clearly seen by adjusting the black level. Also the R and B
pedestal level can be finely adjusted for each color.

■Electronic Shutter Function
•The variable electronic shutter built into the CCD imager enables the DXC-990/990Pand DXC-390/390P
to capture clear images of moving objects. The shutter speed can be manually selected from
a wide range of speeds (up to 1/100000).
•The Flickerless mode allows you to obtain flickerless images even in fluorescent lighting conditions.
•The ClearscanTM mode reduces the horizontal bands that appear in computer displays when shooting
the display with a conventional video camera.
■Long Term Exposure Function
•When shooting very dark objects or objects in dark lighting conditions, you can manually set the
shutter speed to 1/60 of a second or more to allow more light to accumulate on the CCD sensors,
resulting in enhanced sensitivity.
•By synchronizing the WEN pulse of the camera signal output with an external memory unit such as
a frame grabber unit/board, it is possible to obtain a still picture video.
<Shutter speed calculation of Clearscan mode>
Example: When the value is set to 250 H
(NTSC) 250 63.56 us (1H) + 34.78 us (constant)
= 15924.78 us
= 1/62.8 s
(PAL) 250 64 us (1H) + 35.6 us (constant)
= 16035.6 us
= 1/62.4 s
<Shutter speed calculation of LTE mode>
Example: When the value is set to 5 FRM
(NTSC) 5 1/30 = 0.167 s
(PAL) 5 1/25 = 0.2 s

■Digital Detail
•The detail function adjusts the sharpness of object outlines with minimal noise using digital signal
processor technology
•The unique feature of the function is that the horizontal detail frequency can be changed.
■Linear Matrix
•The Linear Matrix function provides sophisticated electronic adjustment for accurate color reproduction
by adjusting color saturation and hue.
•Besides four preset settings, the R,G,B levels can be independently adjusted.
■Partial Enhance Function
•This function allows a particular color to be selected, and its hue, saturation and detail altered.
•In addition, the detail produced by the high resolution of the camera can be softened or emphasized
in certain parts of the image by Partial Enhance function.
•The designated active area can be set by simply adjusting the area detect cursor.
