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.
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. Shutter The CCD exposure time can be set between the maximum 2 seconds and minimum 1/20,000 seconds.
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 dynamic range. Gamma ON (2) Output Gamma ON (1) Gamma OFF Input Concept of Gamma Characteristics Sharpness Used for adjusting sharpness of the image.
DFW-SX900 DFW-X700 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.
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 When frame rate is reduced 7.5 fps = approx. 133 ms 3.75 fps = approx. 267 ms 15 fps = approx. 67 ms 7.5 fps = approx.
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. VD Inside Camera SUB SG ,,, B Exposure Time A Isochronous C Green Green Front Panel LED Orange Orange Operations When Frame Rate is Reduced Camera A [ms] B [ms] C [ms] Approx. 8 Approx. 240 Approx. 26 Approx.
DFW-SX900 DFW-X700 FUNCTIONS When the frame rate is reduced in the extended exposing mode, the timing will be as follows. VD Inside Camera SUB SG Exposure Time ,, B A Isochronous Green Front Panel LED Green Orange Operations in Extended Exposing Mode (In the Case of 2 Frames) When Frame Rate is Reduced Camera DFW-SX900 (3.75 fps) DFW-X700 (7.5 fps) A [ms] B [ms] Approx. 8 Approx. 240 Approx. 2.4 Approx.
DFW-SX900 DFW-X700 FUNCTIONS External Trigger Shutter This function is useful for the following cases. When capturing the images according to an arbitrary external trigger When capturing the images at same time with several cameras Inputting trigger and pulse conditions Input external triggers to the “TRIG IN” connector on the rear panel of the camera using the 4-pin connector provided. As shown in the figure, the pin 3 is the “Trigger Input” and the pin 2 is the “GND”.
DFW-SX900 DFW-X700 FUNCTIONS Internal operations of camera in trigger shutter operation mode An about 3 µs width SUB pulse is generated immediately after trigger is input. Signals accumulated in the CCD sensor until then are eliminated, after which exposure is started. After the exposure time based on the shutter speed set passes, VD is generated inside the camera. (Specifically, VD is generated about 10 µs before exposure ends.
DFW-SX900 DFW-X700 FUNCTIONS 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. All trigger inputs to the camera during the “Trigger Acceptance Prohibition Period” will be ignored.
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 partial scan mode (Format_7).

DFW-SX900 DFW-X700 SETTINGS OF CAMERA CONTROL AND STATUS REGISTER General precautions for partial scan function When settings of CSR related to partial scan mode (F0F0060Ch, F1000008h, F100000Ch, F1000010h) are changed, the camera will recalculate the specified value of CSR F1000140h Packet Para Inq each time. If incorrect settings are performed for CSR related to partial scan mode with the CSR F0F00614h Iso_EN in the ON state, isochronous transmission will be prohibited.

DFW-SX900 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. They become effective after the VD period set to the CSR has been completed and the next VD pulse is generated as shown in the following figure.
DFW-SX900 DFW-X700 COMMAND SETTING AND OPERATION TIMING One Shot CMD and actual operation timing As shown in the following figure, it takes at least about 1 V for the actual isochronous transmission to start after the One Shot command (CSR F0F0061Ch) has been set to the CSR of the camera. (VDs are the reference signals inside the camera and cannot be observed from outside the camera.) Set One Shot in this period VD 1V Approx. 8.0 ms (DFW-SX900) Approx. 2.
DFW-SX900 DFW-X700 COMMAND SETTING AND OPERATION TIMING As shown in the following figure, it takes at least about 50 ms for external trigger signals to be not received after the Trigger OFF command has been set to the CSR (F0F00830h) of the camera. When low frame rate at which the transmission of one image takes a long time is selected, isochronous transmission may not have completed when Trigger OFF is executed. In this case, output of normal moving images will start after transmission completes.
