Color coding of this image sensor & Readout

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.

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.

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.
