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 15 times of the value with which Y is Y
A
, then measure the averaged illuminance
output value (Y = Y
SAT
).
3. Adjust the light intensity to 500 times of the value with which Y is Y
A
, 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.
