2. Lens
SDC-30/33 lens uses a fixed focus method, and can take a photograph clearly at over 1 meter distance (optimal
quality is between 1.5 and 3 meters).
3. Color Filter
Color filter, which remove, the color information on CCD, adapts RGB method
for best color characteristics and Bayer method for best.
4. CCD(MN3776PE) and V Driver(MN3112SA)
CCD converts the optical image to an electrical signal and is similar to an
existing camcorder (except for the scanning method). The camcorder method
uses interlace scanning, which outputs a field image every 1/60 second. (First
field consists of odd lines, the second field consists of even line, and a complete
picture consists of two fields. However, SDC-30/33 uses a the progressive
scanning method, which outputs a frame every 1/30 second (and has excellent vertical resolution).
The image is output at Pin 1 of CCD, and is input to Pin39 of analog signal process IC (IC203) through TR (Q201).
V Driver IC (MN3112SA) mixes each CCD driving pulse from Timing Generator IC, and converts it to
the required voltage.
