TEST CONDITION
1. Use a light source with color temperature of 3,200K hallogen lamp and CM-500S for IR cut filter.
The light source is adjusted in accordance with the average value of Y signals indicated in each item.
COLOR FILTER ARRAY
The color filter array of this image sensor is shown in the right figure. this complementary mosaic CFA is used with
the operation of field integration mode, where all of the photosensors are read out during each video field. The
signals from two vertically-adjacent photosensor lines, such as line couple A1 or A2 for field A are summed when
the signal charges are transferred into the vertical transfer CCD column. The read out line pairing is shifted down
by one line for field B.
The sensor output signals through the horizontal register (H-CCD) at line A1 are [G+Cy], [MG+Ye], [G+CY],
[Mg+Ye]. These signals are processed in order to compose Y and C signals. By adding the two adjacent signals at
line A1, Y signal is formed as follows
C signal is composed by substracting the two adjacent signals at line A1
