7. 5 Partial Read

( 1 ) Partial Scanning OFF (All pixels scanning)

In this mode, all pixels independent signal from the DIGITAL connector is output each 1/20 second (Line order output).

Video interval image

1/20s (1592H)

( 2 ) Partial Scanning ON

In this mode, the pixel signal of the vertical center portion from the DIGITAL connector is output.

In the E.✽✽fps mode, the partial scanning and the all pixels scanning can be switched by the DIGITAL terminal (CC2: partial scanning control signal).
