11-4 DATA REDUCTION FUNCTIONS
The camera provides 9.4 megapixels resolution at 120 fps and 16 bit of gradation.
Then the camera outputs 2.2 GB of data per second, and large capacity of storage device would be
necessary to store such a large amount of data.
The amount of data can be reduced by 12 bit or 8 bit digital output. The amount of data can be three
quarters of original 16 bit data and each pixel have 4096 steps of gradation with 12 bit digital output. And,
with 8 bit digital output, the amount of data can be the half of original 16 bit data and each pixel have
256 steps of gradation. When you use USB interface, the frame rate can be faster with 12 bit and 8 bit
digital output.
The steps of gradation for each pixel would be reduced with 12 bit and 8 bit digital output. However, the
look up table function can minimize the lack of gradation by choosing required range of intensity level.
User can specify the range of intensity level for the look up table by 16 bit value.
