Image processing circuit
The CCD is driven by the drive pulses put out from the GA-SEN pulse generation
circuit. The image analog signals put out from the front CCD and the back CCD
are converted by the AD converter (IC1003, IC1004, IC1005, IC1006, IC1009,
IC1010) to digital signals for the R, G, and B components, and they are given as
input to the image input processing gate array GA-SEN (IC1012, IC1013). As the
R, G, and B sensors of the CCD are arranged staggered in subscanning
direction, GA-SEN performs line deviation correction after shading correction
and MTF correction have been performed, and then the signal is put out via the
MOTHER Board as input to the image processing gate array GA-IMG (IC3013) on
the I/F Board. The shading RAM, the MTF RAM, and the line correction RAM
connected to GA-IMG store these processing calculation data temporarily. And
GA-SEN has a built-in pulse generation circuit for chopping drive of the lamps,
and the lamps are driven via a lamp driver (LAMP INVERTER). GA-IMG performs
image processing like binary-coded processing, pseudo-gradation processing
(dithering, error diffusion processing), color drop-out processing, etc. The
