Data Processing - Ricoh Beluga-C1 Training

CIS: Eight-bit (256 levels per pixel)
Data input to IPU board: Eight-bit (256 levels per
pixel)
Data output from the IPU to the VDB: Two-bit (4
levels per pixel)
Data output from the VDB to the LED print head
(LPH): Five-bit (32 levels per pixel)
Only two of these 32 levels are used for any one
image.
A gamma curve in the VDB board selects which
four levels to use for the image.
Slide 164
Go over the points on the slide.
The LEDs in the print head light at 10% of their full power.
To make the 32 grades, the power is divided into 32 equal intervals.
For example, if the gradation for a certain pixel is 17, the LED for that pixel
will be on at 17/32 of the power.
The base (32/32) power is always at 10% of full possible LED power.
