1/3 INCH CCD IMAGE SENSOR FOR VGA COMPATIBILITY
INTRODUCTION
The KC73133C is an interline transfer progressive scan type square pixel CCD area image sensor of 1/3 inch optical format developed for VGA. The electron accumulation time can be changed by the electronic shutter function and it is possible to obtain a frame still image without a mechanical shutter. High resolution and good color reproduction are accomplished by using mosaic R, G, B primary color filters. It is suitable for still cameras and PC input cameras.

TEST METHODS
1. Measure the light intensities(L) when the average illuminance output value(Y) of green pixels Gr is equal to the standard illuminance output value of 150mV (YA), and when it is equal to half of 150mV, 1/2 xYA. repeat for Gb. and calculate Sgr, Sgb, and Sg.
S gr 1 1 Y A - -- Y A Y A - -- Y A 2 2 = ---------------------------, S gb = ---------------------------, S g = S gr + S gb L YA - L 1 L YA - L 1
-- YA 2 -- YA 2
The sensitivities for red and blue pixels, Sr and Sb, are also measured in the same way.
Sr Sb R r = ----- , R b = ----Sg Sg
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. When the Gr pixel signal value, Ygr is 150mV, mearsure the Gb, R, B pixel signal values, Ygb, Yr, and Yb respectively. Adjust the light intensity until 500 times of the illumination under which 150 mV of Gr pixels value is obtained, is reached. Remove the read-out clock and drain the signal in photosensors by electronic shutter operation during the horizontal blanking time without changing other clocks. Measure the maximum output value YSM regardless of the pixel type..
Y gr + Y gb + Y r + Y b 1 - 1SM = Y SM / ---------------------------------------------- x -------- x ----- x 100 ( % ) 4 500 10
4. Measure the light intensity(LBM) on which the Y signal output value of the optical black pixels (OBP) is rapidly increased with the increasing light intensity.
L BM BM = ---------L YA
5. Measure the maximum and minimum illuminance output value (YMAX, YMIN) when the light intensity is adjusted to make Y to be YA.
Y MAX - Y MIN U = -------------------------------- x 100 ( % ) YA
6. Measure YD with the horizontal idling time transfer level as reference, when the device ambient temperature is 60 C and all of the light sources are shielded.

KC73133C
7. Follow test method 6, measure the maximum (DMAX) and minimum illuminance output (DMIN).
D = D MAX - D MIN
8. When the Gr pixel signal value is 150mV, measure the maximum and minimum output pixel values (YMAX(Gr)), YMIN(Gr)), Repeat for Gb, R, B under the each pixel value,150mV
Y MAX ( i ) + Y MIN ( i ) DSi = ------------------------------------------- x 100 ( % ) Yi
where i = Gr, Gb, R, B
9. Adjust the light intensity to make the each pixel value, 150mV, using red(R), green(G) and blue(B) optical filters respectively and measure the differences (YR, YG, YB) between the signal lines.
Y i Lci = ----------------- x 100 ( % ) 150mV
where i = R, G, B

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.
