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 (Y
A
) and when half of 150mV (1/2 Y
A
).

2. Adjust the light intensity to 10 times that of Y signal output average value (Y
A
= 150mV) , then test Y signal
minimum value (Y = Y
SAT
).
3. Adjust the light intensity to 500 times that of Y signal output average value (Y
A
= 150mV), 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 (Y
SM
).

4. Adjust the light intensity to 1,000 times of the value with which Y is Y
A
, then inspect whether there is blooming
phenomenon or not.
