9 DFW-SX900 DFW-X700 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. For details on the s[...]

10 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. * EV16 for X700 EV7 A[...]

11 DFW-SX900 DFW-X700 FUNCTIONS Gamma Used for setting gamma compensation to OFF, ON (1), or ON (2). OFF : Outputs CCD signals for image processing linearly. ON (1) : For obtaining natural gradation taking into account the characteristics of the monitor. ON (2) : For obtaining three-dimensional images with a subject that has a small luminance dynam[...]

12 DFW-SX900 DFW-X700 FUNCTIONS 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 Saturation Used for adjusting the saturation of the image. The saturatio[...]

13 DFW-SX900 DFW-X700 FUNCTIONS Operations in Normal Mode Exposure and readout are repeated according to the VD pulses inside the camera. As the operating timing of the camera differs according to the frame rate, it is described below. The frame rates are shown in the following table. Camera DFW-SX900 DFW-X700 When power on 7.5 fps = approx. 133 ms[...]

14 DFW-SX900 DFW-X700 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. Operations When Frame Rate is Reduced Time until Data is Read Out and[...]

15 DFW-SX900 DFW-X700 FUNCTIONS When the frame rate is reduced in the extended exposing mode, the timing will be as follows. Operations in Extended Exposing Mode (In the Case of 2 Frames) When Frame Rate is Reduced Time until Data is Read Out and Output Period of Data Camera DFW-SX900 (3.75 fps) DFW-X700 (7.5 fps) A [ms] Approx. 8 Approx. 2.4 B [ms[...]

18 DFW-SX900 DFW-X700 FUNCTIONS External Trigger Shutter Operations When Frame Rate is Reduced 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 readou[...]

19 DFW-SX900 DFW-X700 FUNCTIONS 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 parti[...]
