FUNCTIONS

Saturation

Used for adjusting the saturation of the image.

The saturation can be changed by about more than 150% from the factory setting.

Isochronous Start/Stop

Used for turning ON/OFF the output of IEEE1394 isochronous transmitted images. When image output is set to ON, the LED in front of the camera will light up in orange.

One Shot

Used for outputting only one image data (one frame) in the Isochronous OFF state. The difference between this function and Trigger described on the next section is that image input is started by the IEEE1394 command instead of external trigger signals. The timing at which exposure starts is also undefined (within 133.3 ms after the command is received with DFW-SX900 and within 66.7 ms with DFW-X700).

The LED in front of the camera lights up in orange when image data is isochronously transmitted by the One Shot function.

Trigger

Used for setting the external trigger mode to ON or OFF. No moving image signals are output in this mode.

Isochronous output is stopped at the point Trigger ON is set even in the Isochronous Start state. When external trigger pulses (TTL level, negative polarity, pulse width above 1 ms) are input, one image (one frame) exposed for the specified time (specified at the shutter) will be output from that instant. The time to the start of image data output after the external trigger pulse is input can be changed according to the exposure time.

Paint

Used for changing the R-gain and B-gain by only the values specified at R-offset and B-offset respectively in the use of One Push White Balance. Use of this function is recommended when not adjusting White Balance to white. For example, when viewing a subject on the white 6,800 K monitor using a 3,200 K light source, this function can be used to adjust colors on the monitor to the same state as viewing a subject with the naked eye using a 3,200 K light source.

Y/Cr/Cb → R/G/B conversion

The DFW-SX900/X700 outputs Y/Cr/Cb signals as digital image signals.

The equations for converting these signals to R/G/B signals are as follows.

R ≈ 1.4022Cr + Y

B ≈ 1.7710Cb + Y

G ≈ Y – 0.7144Cr – 0.3457Cb
