Color coding of this image sensor & Readout
B2
Gb B Gb B
The primary color filters of this image sensor are arranged in the
R Gr R Gr
layout shown in the figure on the left (Bayer arrangement).
A2 _{Gr and Gb denote the G signals on the same line as the R signal}
B1
Gb B Gb B
and the B signal, respectively.
For frame readout, the A1 and A2 lines are output as signals in the
R Gr R Gr
A1 ^{A field, and the B1 and B2 lines in the B field.}

Note) Blacked out portions in the diagram indicate pixels which are not read out.
Output starts from the line 5 in high frame rate readout mode.
1. Frame readout mode
In this mode, all pixel signals are divided into two fields and output.
All pixel signals are read out independently, making this mode suitable for high resolution image capturing.
2. High frame rate readout mode
All effective area signals are output in 1/4 the period for frame readout mode by reading out two lines for
every eight lines. The number of output lines is 325 lines.
This readout mode emphasizes processing speed over vertical resolution.
