KC74129C 1/4 INCH CCD IMAGE SENSOR FOR PAL CAMERA
1
INTRODUCTION
The KC74129C is an interline transfer CCD area image
sensor developed for PAL 1/4 inch optical format video
cameras, surveillance cameras, object detectors and image
pattern recognizers. High sensitivity is achieved through the
adoption of Ye, Cy, Mg and G complementary color mosaic
filters, on-chip micro lenses and HAD (Hole Accumulated
Diode) photosensors. This chip features a field integration
read out system and an electronic shutter with variable charge
storage time.

TEST CONDITION
1. Use a light source with color temperature of 3,200K hallogen lamp and CM-500S for IR cut filter.
The light source is adjusted in accordance with the average value of Y signals indicated in each item.
COLOR FILTER ARRAY
The color filter array of this image sensor is shown in the right figure. this complementary mosaic CFA is used with
the operation of field integration mode, where all of the photosensors are read out during each video field. The
signals from two vertically-adjacent photosensor lines, such as line couple A1 or A2 for field A are summed when
the signal charges are transferred into the vertical transfer CCD column. The read out line pairing is shifted down
by one line for field B.
The sensor output signals through the horizontal register (H-CCD) at line A1 are [G+Cy], [MG+Ye], [G+CY],
[Mg+Ye]. These signals are processed in order to compose Y and C signals. By adding the two adjacent signals at
line A1, Y signal is formed as follows
C signal is composed by substracting the two adjacent signals at line A1

Next, the signals through H-CCD at line A2 are [Mg+Cy], [G+Ye], [Mg+Cy], [G+Ye]. Simmilary, Y and C signals are
composed at line A2 as follows
Accordingly, Y signal is balanced in relation to scanning lines, and C signal takes the form of R-Y and -(B-Y) on
alternate lines.
It is same for B field.
TEST METHODS
1. Measure the light intensities (L) when the averaged illuminance output value (Y) is the standard illuminance
output value, 150mV (YA) and when half of 150mV (1/2 YA).
2. Adjust the light intensity to 15 times of the value with which Y is YA, then measure the averaged illuminance
output value (Y = YSAT).
3. Adjust the light intensity to 500 times of the value with which Y is YA, then remove the read-out clock and drain
the signal in photosensors by the electronic shutter operation in all the respective horizontal blanking times with
the other clocks unchanged. Measure the maximum illuminance output value (YSM).
4. Adjust the light intensity to 1,000 times of the value with which Y is YA, then inspect whether there is blooming
phenomenon or not.

HANDLING INSTRUCTIONS
•Static Charge Prevention
CCD image sensors can be easily damaged by static discharge. Before handling, be sure to take the following
protective measures.
—Use non chargeable gloves, clothes or material. Also use conductive shoes.
—When handling directly, use an earth band.
—Install a conductive mat on the floor or working table to prevent generation of static electricity.
—Ionized air is recommended for discharging when handling CCD image sensor.
—For the shipment of mounted substrates, use boxes treated for the prevention of static charges.
•Soldering
—Make sure the package temperature does not exceed 80 °C.
—Solder dipping in a mounting furnace causes damage to the glass and other defects. Use a grounded 30W
soldering iron and solder each pin in less than 2 seconds. For repairs and and remount, cool sufficiently.
—To dismount an imaging device, do not use a solder suction equipment. When using an electronic
disoldering tool, use a thermal controller of the zero cross on/off type and connect to ground.
•Dust and Dirt Protection
—Operate in the clean environments (around class 1000 will be appropriate).
—Do not either touch glass plates by hand or have object come in contact with glass surface. Should dirt
stick to a glass surface blow it off with an air blow (for dirt stuck through static electricity ionized air is
recommended).
—Clean with a cotton bud and ethyl alcohol if the glass surface is grease stained. Be caerful not to scratch
the glass.
—Keep in case to protect from dust and dirt. To prevent dew condensation, preheat or precool when moving
to a room with great temperature differences.
—When a protective tape is applied before shipping, just before use remove the tape applied electrostatic
protection. Do not reuse the tape.
•Do not expose to strong light (sun rays) for long period, color filter are discolored.
•Exposure to high temperature or humidity will affect the characteristics. accordingly avoid storage or
usage in such conditions.
•CCD image sensors are precise optical equipment that should not be subject to mechanical shocks.
