Codec LSI 

(3)    “Picture Master Full HD” High Resolution Image Processing Engine consists 
of  “High Resolution Camera Image Processing LSI for Full High Definition“ which 
effectively processes the massive data captured by the 5.3 mega pixel CMOS image 
sensor, and “High Quality Audio/Video Codec LSI” which implemented MPEG4 
AVC/H.264 CODEC, which is 1.5 to twice efficient compared with MPEG2.   

i)    “High Resolution Camera Image Processing LSI” has Adaptive DNR (Dynamic 
Noise Reducing Method) technology which analyzes the captured image and reduces 
noise and Advanced CCM (Correlative Coefficient Multiplying Method) Circuit to 
control false color signal.  It improves picture quality by reducing noise and by 
preventing data to be used up by noise signal during compression at the same time to 
capture beautiful high definition video.     

ii)  “High Quality Audio/Video Codec LSI” has a uniquely developed algorism for 
high-quality motion picture.  It switches process methods between field and frame in 
macro block depending on the amount of motion happening within the frame to process 
fine quality video image in scenes with a lot of action.    The unique algorism adaptively 
judges and switches encoding methods depending on the condition of images judged by 
the correlation of different frames, or predictions made from a single frame.  The 
algorism judges the amount of code to allocate by calculating how much picture 
quality deterioration can be recognized at playback.   

The BD camcorder has HDMI terminal which transfers 1920x1080 pixel full high-definition video and clear 
audio digital data with one cable.    A HDMI cable which is widely available in the market can be used for 
connection.   

 

The contents recorded onto the HDD can be easily dubbed in the original high definition quality to BD or 
converted to standard definition when dubbing to DVD utilizing the camcorder without the hassle of 
connecting the camcorder to other devices. 

(*2)

     

*2:      The camcorder must be powered via the AC adapter/charger for dubbing from HDD to disc.   

   

The disc media being copied can be selected from 8cm BD-RE/-R,DVD-RAM/-RW/-R depending on the 
type of disc that best suits the format of the player.  The user can choose from four pre-set dubbing 
modes, and if the contents do not fit into the disc, the user can also select auto divide dubbing.     

1)  “New” selects only the uncopied scenes on the HDD and dubs to disc.     

2)  “Date” selects the scenes recorded on the specified date and dubs to disc.     

3)  “All” dubs all the contents on the HDD.     

4)  “Select” dubs the scenes selected by the user.     

 

The full high-definition video recorded on the HDD or the 8cm BD-RE can be edited with the camcorder.   
Easy editing functions such as split, delete, and connect can be made without using a PC.    User can also 
create play list, and rearrange the orders of playback within the play list.   

 

Approximately 4.32 mega pixels high resolution still photos can be recorded on the SD memory card.    10x 
optical zoom lens will capture images form wide to telephoto angle.  (Field angle 35mm at 4x3 still is 
equal to 34.5-345mm converted to film) 

 

The best shot from the recorded full high-definition video can be captured as approximately 2.07 mega 
pixels photo images and stored into the SD memory card.    The captured photo can then be printed out 
easily with a printer capable of reading SD memory card.     

 

The BD camcorder can start recording in one second by pressing the “Restart” button instead of turning
