Composition of color coding and output signal
The color filters of this image sensor are arranged in the layout shown in the figure below.

Gr and Gb denote the G signals on the same line as the R signal and the B signal,
respectively.

1. 1/60s interlaced
In this mode, the signals are output in a 1/60s period using the two output pins (VOUT1, VOUT2).
The signals from two adjacent horizontal lines are simultaneously output from the respective output pins.
The lines output from the output pins are changed over with each field. The VOUT1 signal after it has passed
through the CDS and other external circuits or the signal produced by adding the VOUT1 and VOUT2 signals
accommodate interlaced scanning. In the Odd field, R signal and Gr signal are output from VOUT1 pin and
Gb signal and B signal are output from VOUT2 pin. In the Even field, Gb signal and B signal are output from
VOUT1 pin and R signal and Gr signal are output from VOUT2 pin.
2. 1/30s non-interlaced
In this mode, the signals are output in a 1/30s period using only one output pin (VOUT1).
Unlike the 1/60s interlaced mode described above, the external circuit can be simplified. The imaging
characteristics also differ from those of the other modes. R signal and Gr signal lines and Gb signal and B
signal lines are output sequentially from VOUT1 pin only.
