M66335FP

FACSIMILE IMAGE DATA PROCESSOR

DESCRIPTION

Built-in A/D converter of a 7-bit flash type

•

The M66335 is a facsimile image processing controller to turn into

binary signals analog signals which have been output through photo-

electric conversion by the image sensor.

Built-in image processing memories

Uniformity correction memory, Line memory, Error memory, γ cor-

rection memory

The image processing functions includes peak value detection,

uniformity correction, resolution change, MTF compensation, γ cor-

rection, detection of background/character levels, error diffusion,

separation of image zones, and designation of regions.

This controller contains not only the analog processing circuit, the A/

D converter of a 7-bit flash type and image processing memory, but

also the image sensor and the interface circuit to the CODEC (Coder

and Decoder). Therefore, this LSI alone is capable of image pro-

cessing.

External output interface for converted binary data

Serial output (→ M66330)

•

DMA output

External output interface for multivalued data

DMA transfer of data compensated for uniformity

Various image processing functions

•

Uniformity correction

Resolution change from 50% to 200% (by the 1% step)

MTF compensation (2-dimensional processing, capable of correc-

tion for each character/photo)

γ correction (capable of correction for each character/photo)

Detection of background/character levels

Change to pseudo-halftone

FEATURES

High speed scan (max. 2 ms/line, typ. 5 ms/line)

•

Compatibility with up to the B4 (8 pixels/mm, 16 pixels/mm) image

Error diffusion (64 tone steps through 6-bit processing)

•

sensor

• Organized dither (64 tone steps through the 8 × 8 matrix)

Image zone separation (2-dimensional processing)

5V single power supply

Generation of control signals for the image sensor (CCD, CIS)

•

For CCD: SH, CK1, CK2, RS

For the contact sensor (CIS): SH, CK1, CK2

•

Built-in analog processing circuit (equivalent to the M64291)

•
