1/4 INCH CCD IMAGE SENSOR FOR PAL CAMERA
KC74129C
5. Measure the maximum and minimum illuminance output value (Y_MAX, Y_MIN) when the light intensity is adjusted
to make Y to be Y_A.
U = ^Y-----^M-----^A----^X-_Y----–-_A---^Y-----^M-----^I--^N-- × 100(%)
6. Measure Y_D 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.
7. Follow test method 6, measure the maximum (D_MAX) and minimum illuminance output (D_MIN).
∆D = D_MAX – D_MIN
8. Adjust the light intensity of Y signal output value by strobe light to 150mV (Y_A), calculate by below formula with
measuring the image lag signal which is qenerated by below timing diagram.
Y_LAG = (Y_lag ⁄ 150) × 100(%)
