Setting the Scan Mode

Since the DXC-9100P has a CCD that uses an “all pixels read-out” method, the unit has a frame shutter function. This allows the camera to output full-frame still image only using the electronic shutter.

The camera has the following three scan modes.

•NOR (normal mode)

•F.S (frame shutter mode)

•N.I mode

Each mode is described below using the timing charts.

NOR (normal) mode

This mode is suitable when using the camera output only for monitoring where the frame shutter function is not required.

CCD output 1

(Video signal O E O E O output)

O: Odd

E: Even

One channel of the CCD outputs is used. The video signal is output from the camera without passing through the memory. Odd-field and even-field video signals are output alterntely.

F.S (frame shutter) mode

The video signals for 25 frames are output for one second. This mode is suitable when shooting an object moving at high speed from a fixed position with minimal blurring using the frame shutter function.

1frame (1/25 sec.)

O E O E O

Memory output (video signal output)

O E O E O

CCD output 1

E O E O E

CCD output 2

O: Odd

E: Even

The odd-field signal and the even-field signal are sent to the memory together and they are interlaced in memory and output as the video signal for one frame.
