6.5 IMAGE PROCESSING
6.5.1 OVERVIEW
SBU: The SBU (Sensor Board Unit) converts the analog signal from the CCD to an
8-bit digital signal and sends it to the SIB.
SIB: Relays image signals and controls the scanner.
BICU: The BICU (Base Engine Image Control Unit) performs timing control and
command control. The IPU on the BICU processes auto shading, filtering,
magnification, γ correction, and gradation. The memory controller performs image
compression, decompression, and memory address control (for binary picture
processing mode only)
LD Unit: Performs dual channel multi-beam exposure, multiple exposure, and
synchronous detection.
Controller: Performs dual channel multi-beam exposure, multiple exposure, and
synchronous detection.
