CC640 Digital Camera 

The banner ends with the internal camera temperature displayed in degrees 
Kelvin.  This is intended for diagnostic purposes.  The temperature is displayed 
in degrees Kelvin so that there is no confusion that the temperature represents 
some ambient temperature.  The temperature is internal and can vary 
substantially from the actual ambient temperature.   To convert the temperature 
to degrees Celsius subtract 273 from the value displayed.

7.4  JPEG Compression 

There are 5 selectable levels of JPEG compression:  

•

 

Very High  

(32 Kbytes Typical) 

•

 

High 

(48 Kbytes Typical) 

•

 

Medium 

(72 Kbytes Typical) 

•

 

Low 

(100 Kbytes Typical) 

•

 

None (Lossless)  480 Kbytes Typical) 

These are typical values with the time stamp enabled on the 
image (640x504 pixels).  The size of the images varies with the 
image content. 

NOTE 

Selecting 

None

 will produce the best quality JPEG files with Lossless 

compression.  Lossless compression does not introduce additional distortions 
and every pixel is the same size as in the original image.  Very High
