ICX252AKF
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 G/Ye
channel signal output or the Mg/Cy channel signal output of the measurement system.

Color Coding Diagram
These signals are processed to form the Y signal and chroma (color difference) signal as follows.
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 – G}
B – Y = {(Mg + Cy) – (G + Ye)}
= {2B – G}
are used for the chroma (color difference) signal.
