Text Enhancement
In order to generate a good picture, the SD1210 incorporate a proprietary scheme to
detect text and non-text picture. Then applying the appropriate process to improve the
text image based on the detection of incoming source. By using the text enhancement
function correctly, the text image will be looked more pleasant and near perfect after
scaled up or down. Users can achieve a preferred image by changing the settings in
“text control” register.
3.3.5.
Sharpness Enhancement
No matter how many times the original image got enlarged or shrunk by the internal
interpolator. With the embedded powerful DSP arrays, SD1210 always can enhance
the overall image sharpness (edge) to different degree for the various requirements.
The sharpness can be adjusted bi-directionally which means either going sharper or
softer to certain point set by the user. It’s easy to activate the sharpness enhancement
by program “sharpness control” register.

OSD mixer and LCD interface
At the output stage, the SD1210 performs the OSD mixer function, and then generates
the 24-bit / 48-bit RGB signal to the LCD panel with the correct timing.
3.4.1.
OSD mixer
In the OSD mixer block, the SD1210 mixes the normal output RGB signal with the
OSD signal. The OSD output data is generated based on the “R_OSD”, “G_OSD” and
“B_OSD” pins as well as the “OSD Intensity” data in EEPROM entry. When the
“EN_OSD” is active high, the OSD is active, and the SD1210 will send the OSD data
to the LCD panel. The OSD has 16 different color schemes based on the combinations
of the three OSD color pins and the “OSD Intensity” data. When R_OSD=1, and
OSD_Intensity=0, the SD1010 will output 128 to the output red channel, R_OUT.
When R_OSD=1 and OSD_Intensity=1, the SD1210 will output 255. The same
scheme is used for G_OSD to G_OUT and for B_OSD to B_OUT.
As part of the mixer control function, the SD1210 implements three mixing control
registers, “OSD R Weight” (38H), “OSD G Weight”(39H), and “OSD B Weight”
(3AH). The mixing equation is shown below:
R_OUT = (R_OSD) * (OSD R Weight/255) + R * (1 - OSD R Weight/255)
G_OUT = (G_OSD) * (OSD G Weight/255) + G * (1 - OSD G Weight/255)
B_OUT = (B_OSD) * (OSD B Weight/255) + B * (1 - OSD B Weight/255)
