TEST METHODS

1. Measure the light intensities(L) when the average illuminance output value(Y) of green pixels Gr is equal to the

and calculate Sgr, Sgb, and Sg.

The sensitivities for red and blue pixels, Sr and Sb, are also measured in the same way.

3. When the Gr pixel signal value, Ygr is 150mV, measure 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..

increased with the increasing light intensity.
