Measurement System
Image Sensor Characteristics Measurement Method
Measurement conditions
(1) In the following measurements, the device drive conditions are at the typical values of the bias and clock
voltage conditions, and the frame readout mode is used.
(2) In the following measurements, spot blemishes are excluded and, unless otherwise specified, the optical
black level (OB) is used as the reference for the signal output, which is taken as the value of the Y signal
output or chroma signal output of the measurement system.
Color coding of this image sensor & Composition of luminance (Y) and chroma (color difference) signals
The complementary color filters of this image sensor are
arranged in the layout shown in the figure on the left.
For frame readout, the A1 and A2 lines are output as signals in
the A field, and the B1 and B2 lines in the B field.

Note)
Adjust the amplifier gain so that the gain between [
A] and [
B], and between [
A] and [
C] equals 1.
These signals are processed to form the Y signal and chroma (color difference) signal sa follws.
The approximation:
Y ={G + Mg + Ye + Cy}
×
1/4
=
1/4 {2B + 3G +2R}
is used for the Y signal, and the approximation:
R
Y = {(Mg + Ye)
(G +Cy}
= {2R
