THEORY

OF

BI-98

Board

The

BI-98

board

has

a

CCD

imager.

The

CCD

chip

surface

is

arranged

with

photosensors.

The

incident

light

is

converted

to

electric

charge

according

to

the

intensity

of

the

light

by

the

photosensors,

read

to

registers

from

the

photose

nsors,

and

then

transmitted

to

the

output.

The

registers

consist

of

vertical

registers

and

horizontal

registers,

and

the

electric

charge

converted

by

the

photosensors

is

transmitted

to

the

vertical

registers

adjoining

the

photosensors

in

each

field.

The

electric

charge

transmitted

to

the

vertical

registers

are

transmitted

in

the

vertical

direction

according

to

the

vertical

transmission

clocks

V1,

V2, V3,

and

V4,

and

sequentially

transmitted

The

transmit

to

the

in

the

horizontal

according

to

the

clocks

H1

and

The

converts

the

into

the

voltage

and

the

signal

is

output

from

the

(IC201

The

signals

from

the

CCD

imager

are

separated

into

DATA

and

sample-held

by

the

respective

timings

(SHP,

SHD),

and

then

signal

divided

so

that

the

and

reset

noise

generated

by

the

CCD

mutually

eliminate

each

other,

making

use

of

the

fact

that

the

superimpose

components

of

the

precharger

and

those

of

the

data

are

the

same.

This

mechanism

is

called

the

correlation

circuit

(CDS

circuit).

The

noise

components

of

the

DATA

and

PG

signals

input

to

IC201

are

eliminated

by

the

sample

hold

pulse,

and

the

differences

between

these

signals

are

calculated

to

perform

signal-division.

After

the

is

separated,

it

is

passed

through

the

to

Because

The

This

The

from

the

of

the

controls

the

circuit,

DC

and

In

the

the

mixed

with

the

average

value

and

and

output

to

the

IC

(IC702

Level

is

performed

by

changing

the

(pin

In

the

used

of

In

(video

is

Chroma

Matrix

(IC403

CXA1391)

Inside

the

1C403,

CO

(S2-S1)

and

YO

(S1+8S2)

are

separated

from

the

S1

and

S2

signals,

matrixed

to

make

the

RGB

signal

and

delayed

to

make

the

V

aperture

signal.

The

RGB

signal

is

made

using

the

C1

signal

delayed

by

1H

because

the

CO

signal

is

the

linear

sequential

signal

of

the

2R-G

signal

and

—

(2B-G)

signal.

The

C1

signal

is

made

by

inputting

the

reverse

polarity

output

from

46

of

EC403

to

the

1H

delay

line

ICSO1.

The

signal

is

then

passed

through

the

Q501

buffer,

input

to

48

of

1C403,

passed

through

the

gain

control

amplifier,

and

input

to

the

RGB

matrix

circuit.

In

the

gain

control

amplifier,

the

CO

signal

and

Cl

°

signal

are

set

to

the

same

level

by

the

voltage

of

47

of

IC103.

The

1H

delay

line

is

a

CCD

delay

element.

It

is

operated

in

a

2Fsc

period

by

the

XDL1

and

XDL2

drive

clocks.

The

V

aperture

signal

requires

three

lines

of

signals

actually,

but

in

this

case,

only

two

lines

of

signals

are

provided

(simplified).

The

YO

signal

is

delayed

by

1H

to

create

the

Y1

signal.

The

YO

and

Y1

signal

are

used

as

the

Y

signal

in

the

RGB

matrix.

The

YO

signal

is

output

with

positive

polarity

from

52

of

IC403,

and

input

to

3

of

IC501.

In

this

pin,

it

becomes

a

Y1

signal

delayed

by

1H,

passed

through

the

Q501

buffer

with

negative

polarity,

and

input

to

55

of

IC403.

It

is

then

added

to

the

YO

signal

in

the

gain

control

amplifier,

and

input.to-the

matrix

circuit.

In

the

gain

control

amplifier,

the

YO

and

Y1

signals

are

set

to

the

same

level

by

the

voltage

of

54

of

IC403.

The

RGB

signals

are

made

from

these

2R-G,

-

(2B-G),

and

Y

signals.

White

Balance

(IC401

pPC324/IC402

NJU7022/

1C403

CXA1391)

The

RGB

signals

each

pass

through

the

2-stage

gain

amplifier

to

produce

the

white

components.

The

3200°K

reference

setting

is

simplified,

and

the

R

and

B

control

values

(RV401,

RV408)

are

adjusted

and

balanced

by

fixing

the

gain

of

pins

37

and

40

of

IC403

so

that

the

white

components

can

be

currently

produced

when

the

To

reduce

in

when

value,

the

RGB

are

set

so

that

they

settle

the

Luminance

signal

processing

(IC403

CXA1391/IC801

CXA1592)

Taking

into

consideration

the

delay

generated

by

chroma

matrix

processing,

the

luminance

signal

is

passed

through

FL401

and

FL402

to

adjust

the

delay

amount

and

input

to

64

of

IC403.

The

Y

signal

which

has

been

is

output

from

passed

through

the

for

adjusting

and

input

to

Encoder

(IC801,

The

signals

(R-Y,

B-Y)

output

from

IC403

are

each

to

and

47

of

IC801.

These

are

added

with

the

modulated

signals

and

output

from

of

IC801,

then

passed

through

the

band

and

returned

to

18

again.

Next,

they

are

mixed

with

the

luminance

signal

and

output

from

21

as

the

composite

signal.

The

luminance

signal

is

added

with

the

H

aperture

correction

signal

(pin

33)

and

V

aperture

correction

signal

(pin

42),

and

added

with

the

The

H

aperture

signal

is

level-adjusted

by

the

voltage

of

36

of

IC801.

After

the

noise

level

is

regulated,

it

is

added

to

the

luminance

signal.

By

linking

the

adjustment

voltage

to

AGC,

when

AGC

rises

during

low

luminance,

the

aperture

correction

amount

is

dropped

to

decrease

the

noise.

The

signal

is

passed

through

where

its

is

adjusted

to

and

then

Board

(SSC-C108P

These

A

is

mounted

on

the

AC-172

The

method

is

adopted

as

the

method.

The

commercial-use

power

input

through

the

filter

composed

of

the

and

line

is

rectified

by

D401,

and

input

to

the

switching

transformer

T401.

The

PWM

control

IC

(IC401)

drives

the

switching

FET

(Q401)

to

perform

power

transmission.

The

oscillation

frequency

of

this

control

IC

is

regulated

to

100

KHz

by

the

capacitor

of

The

voltage

is

extracted

from

the

Q401

source

via

R412

and

R413

to

impose

over-current

protection.

The

snubber

circuit

composed

of

D403,

R408,

and

C412

controls

the

switching

to

below

450V.

The

as

its

It

is

compared

with

the

value

of

the

1C504

of

the

VCA-6

board.

If

higher

than

the

current

is

sent

to

the

photo

in

to

decrease

the

and

shorten

The

of

the

is

adjusted

by

of

the

so

that

the

can

be

set.

The
