3-2. Cinema mode De-interlacing (3-2/2-2 pull-down)
When NTSC/PAL interlace signal generated from film (cinema) source or 30p source such as cartoon are
inputted, it does auto-discriminate cinema/30p source and cinema mode de-interlace that suitable for source.
3-3. 3D Noise reduction
This has built-in round type 3D noise reduction function that decreases the noise between frames. In this block
luminance signal and color difference signal can be processed independently.
3-4. Cross color/Cross luminance canceller
This function can decrease the cross color, noise and cross luminance which are generated when NTSC input
signal from composite terminal. By using this function, it can produce vivid image without color blotting and
dot interruption.
4. Scaler block
It implement the up/down scaling of the various input signal of analog and digital that fixed to XGA, WXGA of
output resolution. Full/panorama/zoom display is possible and maximum resolution is WXGA (1366
× 768 and
85MHz pixel clock). Additionally, this has built-in 2scaler system and enable to display 2screen such as POP/PIP.
5. Image quality adjustment block
This has various image quality blocks and enables to implement the image quality adjustment to fix with flat panel
TV.
5-1. Horizontal edge correction (LTI/CTI)
LTI/CTI does edge correction of input signal. It improves the sharpness of image by making the transients of
input signal steep. In this case, it is possible to make natural image because there is no peak such as overshoot
and undershoot attached at the edge part of image. This function operates independently luminance signal and
color difference signal.
5-2. Sharpness (Horizontal/Vertical)
Sharpness can do edge correction of input signal. In this function, unlike the above function, the moderate
peak is added around edge correction. In this case, coring which emphasizes neither an amount of peak nor
slight noise can be controlled by register. This function is operated only for luminance signal.
5-3. Shadow adjuster
Shadow adjuster add the moderate peak at front and back of detected edge of input signal and with added
shadow of image, so it can produce sharpness image.
5-4.White/Black Stretch
As far as White-black stretch is concerned, it stretches the level of white side and black side of Y signal of
YCbCr signal according to white-black peak inside picture of just before field, APL (Average Picture Level) of
luminance, distribution information and microcomputer setting information. White and black peak are the max
value and min value of input data in 1 field. When using white/black stretch, each setting value should be set
properly.
5-5. Flesh color correction
Flesh color correction can extract flesh color and adjust the fresh color without influencing other colors.
5-6. Color phase/Color gain adjustment
The phase adjustment can adjust the hue on entire screen. The color gain adjustment can adjust the density of
colors by controlling the gain of color phase signal. This function can adjust independently by Cb and Cr.
5-7. Color exciter
Color exciter can control the gain of chroma in red, green, blue, magenta, yellow, cyan respectively.
5-8. Brightness/Contrast
Brightness can adjust the brightness of entire screen, and contrast can adjust gain of brightness.
5-9. White balance/Black balance adjustment
This function can do white adjustment and black adjustment of LCD panel.
5-10. Gamma correction
It is possible to make the optional gamma curve that fix to LCD panel characteristic. It is also possible to adjust
R, G and B independently by writing the adjustment value in LUT inside LSI
5-11. Dither
When the signal processing of internal 10/12bit is output by 8/10bits, the dither rounds the 2/4bits of LSB and
output it.
