M663M36623F32PFP

FACSIMILE IMAGE DATA PROCESSOR

DESCRIPTION

0 Analog signal processing circuit control signal generation

CLAMP, S/H, AGC, DSCH

0 Built-in 5-bit Flash Type A-D Converter

0 Bi-level data external input/output interface Serial output

(→M66330)

8-bit MPU bus output with external DMA control signal

0 Image data processing

γ correction

Uniformity correction (block correction in units of 8 pixels)

MTF compensation (1 dimension)

Detector of background and object level (programmable)

Dithering control

The M66332 is a facsimile image processing controller that

converts analog signals that are photoelectrically converted

by an image sensor into bi-level signals.

It has image processing functions such as peak detection,

uniformity correction, γ correction, MTF compensation, de-

tector of background and object levels, dither control, sepa-

ration of image data area, scale down, and area specification.

This controller has a built-in 5-bit flash type A-D converter

and interface circuits to image sensor, analog signal process-

ing circuit, and CODEC (Coder & Decoder) to simplify control

of the readout mechanism.

• Dither method (16 levels using 4 × 4 matrix)

Separation of image data area (1 dimension)

Scale down A3 → B4, A3 → A4, B4 → A4

0 5V Single Power Supply

FEATURES

0 High Speed Scan (MAX. 2 ms/line, TYP. 5 ms/line)

0 A3 (8 pixels/mm) Line Sensor Attachment

0 Image sensor (CCD,CIS) control signal generation

CCD: SH, CK1, CK2, RS

APPLICATION

Contact sensor (CIS): SH, CK1 (or CK2)
