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 intermediate data during processing are stored temporarily in
SDRAM. The data processed by GA-IMG are given as input to GA-IFC. In case of JPEG compression for color images or multi-
level black-and-white images, input to GA-IFC is made via the JPEG compression IC (IC3007). GA-IFC controls the SCSI
control IC (SCSI controller). The SRAM connected to GA-IFC is the image data page buffer. The data which have passed
through GA-IFC are put out to the PC via the SCSI control IC and the SCSI connector.
