  • Page 11: Functions

    FUNCTIONS The DFW-SX900/X700 differs from the conventional analog camera in that no video signals will be output by just supplying power. It will start operating when designated commands are written in the CSR (Control & Status Register) specified in the 1394-based Digital Camera Specification Ver.1.30.
  • Page 12 DFW-SX900 DFW-X700 FUNCTIONS Gain Used for setting the gain of the video signal amplifier. The gain can be set to 180 steps between the standard gain and maximum +18 dB. (1 step is not 0.1 dB.) By setting AUTO to ON, the gain will be automatically adjusted to the appropriate exposure. The range of operations is 0 to +18 dB.
  • Page 13 Color Temperature This function was originally intended for selecting the optical filter. However with the DFW-SX900/X700, the R-gain and B- gain are set to the appropriate White Balance when color temperatures 3,200 K and 5,600 K light sources are used.
  • Page 14 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...
  • Page 15 For the image output timing based on the falling edge of VDs generated inside the camera, image data output starts at the point the A period is passed, and the image data is output during the B period.

  • Page 16 FUNCTIONS When the output frame rate is reduced (3.75 fps of DFW-SX900, 7.5 fps of DFW-X700), images will be read out from the CCD for every VD. However, as every other image is used, the images read out during the isochronous output period will not be used.

  • Page 20 The trigger acceptance prohibition period continues until all of CCD image has been transferred out of the camera. When the transfer frame rate is reduced (3.75 fps of DFW-SX900, 7.5 fps of DFW-X700), data will continue to be transferred even after readout of image has been completed as shown in the figure below. The trigger prohibition period continues until data transfer ends.
  • Page 21: Partial Scan Mode

    The partial scan mode is a function for outputting part of the full images a region of interest on the whole image. When the screen size needs to be set to the full size (DFW-SX900: SXGA, DFW-X700: XGA), data volume and system load can be decreased by setting the required screen size using the partial scan mode (Format_7).

  • Page 40: Command Setting And Operation Timing

    DFW-X700 COMMAND SETTING AND OPERATION TIMING The DFW-SX900/X700 operates synchronously with internal pulses called VD. VDs are reference signals inside the camera and cannot be observed from outside the camera. Even if commands are set to the CSR of the camera, it does not mean that they become effective the instant they have been written.
  • Page 41 Trigger Mode command and actual operation timing As shown in the following figure, it takes about 430 ms (DFW-SX900), 360 ms (DFW-X700) at the least for external trigger signals to be received (Trigger Mode) after the Trigger ON command has been set to the CSR (F0F00830h) of the camera.
  • Page 42 Images will be isochronously output after the A period from the falling edge of the VD. (The following figure shows an example where the frame rate is 7.5 fps for the DFW-SX900, and 15 fps for the DFW-X700.) External Trigger Signal Ext Trig.
