XCD-SX910CR/X710CR XCD-SX910UV XCD-SX910/X710

The XCD-SX910CR/SX910UV/SX910 with its 1/2type PS IT CCD, and the XCD-X710CR/X710 with its 1/3-type PS IT CCD are high-resolution industrial-use digital video camera modules. Utilizing an IEEE 13941995 digital interface, transfer rates as high as 400 Mbps are realized. In addition, the use of digital signals enables industrial-use image processing without “image deterioration,” an important plus in the industrial world. Moreover, the use of a square pixel CCD eliminates the need for aspect ration conversion during image processing. Finally, a vibration resistance feature permits use of these units in all types of inspection and imaging devices.

What is the IEEE1394?

The IEEE1394 is the standard serial bus for sending and receiving digital data. It is prescribed as “IEEE* Std. 1394-1995.” The most outstanding feature of this interface is that it realizes transfer speeds of up to 400 Mbps and can handle large image data size. The interface is also capable of “Isochronous transmission” which transmits data real-time, for up to 64 channels. Connectors can be inserted and disconnected while the unit is turned on, and no terminators and no ID settings such as those necessary for the SCSI interface are required.

High-resolution

The XCD-SX910CR/SX910UV/SX910 adopts an SXGA-compatible 1.45 M-pixel CCD while the XCDX710CR/X710 adopts an XGA-compatible 800 Kpixel CCD to produce high-picture quality images.

External trigger function

The external trigger shutter function allows the image exposure to be coordinated with external equipment and moving objects. For exposure time, the unit is equipped with Trigger Mode 0, which indicates the length of the exposure using the shutter parameter, and Trigger Mode 1, which controls exposure time by the width of the trigger signal. It is also able to utilize a software trigger initiated by a command from a program running on a host computer.

XCD-SX910CR/X710CR XCD-SX910UV XCD-SX910/X710

Partial scan output image format

It is equipped with a partial scan feature that divides an entire screen image into 16 × 16 sections, allowing it to be output as an optionally designated rectangle within the required limits. Use of this function enables frame rates faster than normal speeds, thus enabling efficient image capture. In addition, partial scan operations can be carried out even without the input of an external trigger.

Brightness

This camera supports brightness control. This makes fine adjustment of the black level possible. (The former model, XCD-SX910/X710 (firmware version

1.07) does not support brightness control.)

Gain

Both Manual and Auto Gain setting are available with this camera. The variable range extends from 0 to 18 dB (XCDSX910CR/X710CR)/0 to 24 dB (XCD-SX910UV*/ SX910*/X710*), and the unit is designed so that the gain can be subdivided and set to any of 640 steps. At the factory default setting, the gain is set to 0 dB. When Auto gain is selected, the gain is adjusted automatically, based on the brightness of the subject. At this time, the reference level (target point) is set in the AutoExposure register.

Functions

The relationship between the parameter and the exposure time is given by the following formulas. Where

P = Parameter (003h ~ 424h) E = Exposure time (s) P >= 3 ~ P <= 1000

E =

P > 1000 ~ P <= 1150

E = (P – 1000)*0.1 + 1

For details on Auto Exposure, see page 9. The XCD-SX910CR/SX910UV/SX910 and XCD-

X710CR/X710 are not compatible with the XCDSX900 and XCD-X700 in Gain settings.

*: If you set the gain to +18 dB or higher, the S/N ratio will

be severely degraded. Note this characteristic when you use the XCD-SX910UV/SX910/X710.

Shutter

This camera allows both Manual and Auto Shutter setting. The variable range extends from 10 microseconds to

17.5 seconds; relative control values are indicated by a 12-bit integer, and absolute control values are indicated using a 32-bit floating point value. The shutter settings for the XCD-SX910CR/ SX910UV/SX910 and XCD-X710CR/X710 are the same, but these settings differ from some of those for the XCD-SX900 or XCD-X700.

Functions

For long exposure times

When exposure times longer than the currently set frame rate cycle are set, the camera enters the long exposure time mode, and the actual frame rate is slowed in accordance with the exposure time.

Absolute Control Value for the Shutter

Control of exposure time using absolute values is possible. The values are indicated using a 32-bit floating point value. (Unit: sec.) The control steps are synchronized with the pixel clock, and as the pixel clock is 30.5 MHz, one step is approximately 32.8 ns. The range for these values extends from 10 microseconds to 17.5 seconds.

Programming example;

union {

DWORD dwValue; // 1394 is expressed in quadlets, float fValue; //

} AbsoluteShutterValue;

exposure time is indicated in seconds.

Trigger Shutter

Trigger shutter is useful for capturing images in response to a trigger that starts the exposure to match a preset timing. It can also be used to capture an image using multiple cameras with the same timing. When a trigger shutter is used, the required trigger is input via the BNC connector on the rear panel. The input signal is a 5-volt negative pulse. The falling edge of the signal is detected as the trigger, and the unit is equipped with an exposure time consisting of the shutter parameter set as trigger mode 0, and trigger mode 1 that controls the exposure timing using the width of the trigger signal pulse. When trigger mode 0 is used, the minimum width of the trigger is 10 microseconds. When trigger mode 1 is used, there is no limit to the exposure time.

This unit can also be used with a software trigger that issues the trigger signal via a software command. Both trigger mode 0 and trigger mode 1 can be used with software triggers.

Trigger shutter

AbsoluteShutterValue.fValue = Exposure time; WriteQuad(AbsoluteShutterOffsetAddress,

AbsoluteShutterValue.dwValue);

WriteQuad is a virtual function used to write in the register. AbsoluteShutterOffsetAddress is an offset address for the absolute value control. See page 25 for the formula for the offset address.

Auto Exposure

AutoExposure is a function that automatically adjusts the gain and shutter settings, based on the brightness of the subject. When this function is used, make sure the video mode is set to one of the following modes. This function is not effective in any other modes.

Functions

Pan/Tilt

Pan/Tilt is a function used to move a camera up and down or left and right, however this camera supports a video mode much smaller than the CCD’s effective pixels by cutting out images from the whole screen. You can specify the portion to be cut out using Pan/ Tilt commands. One unit of movement is two pixels. Refer to the table for the video modes in which Pan/ Tilt commands can be used and the variable ranges for the mode. The values in parentheses are the initial settings.

When a video mode is changed, the initial Pan/Tilt values for the mode are set. On the XCD-SX910CR/X710CR, if you set the value of Pan/Tilt to maximum, the pixels on the edge of the picture may not be output correctly.

XCD-X710CR/X710

Memory Channels

This camera is equipped with two channels nonvolatile memory to hold camera settings. The settings of all camera features and the video mode can be stored. The camera memorizes the channel most recently used to read out the setting information, and retains it, even if the power is turned off. Therefore, the camera loads the information from that channel when the power is turned on. The video mode settings are loaded only when the power is turned on. To start up the camera with the desired setting, perform the following procedure.

1 Make changes to the camera features or the video

mode settings.

2 Store the current setting in Memory Channel 1 or

Memory Channel 2.

3 Load the information that was stored in step 2.

Thus, when you start up the camera the next time, the settings that you have made will be loaded automatically.

Using the CameraInitialize command, the setting information stored in the channels is cleared and the camera features and the video mode are initialized. To preserve the information in the channels, be sure not to send the CameraInitialize command while driver software or application software is starting up. The value of Pan/Tilt is initialized when the video mode is changed. To preserve the value, be sure not to change the video mode while driver software or application software is starting up, or before sending the video start command.

Partial Scan

The partial scan mode is a function for outputting part of the full images a region of interest on the whole image. Based on the unit cell as the unit, continuous parts can be selected. Only rectangles can be selected. The screen cannot be cut in convex and L shapes.

Functions

Cutting by partial scan mode

Vertical (Vertical Direction)

Horizontal (Horizontal Direction)

The unit size of both the XCD-SX910CR/SX910UV/ SX910 and the XCD-X710CR/X710 is 1/256th of the whole screen, divided into 16 sections, horizontally and vertically. The partial scan mode for the XCD-SX910CR/ SX910UV/SX910 and the XCD-X710CR/X710 has had a partial read out function added, and there is a frame rate speed-up feature for use when the vertical width of the cut-out is small. But because of the structure of the CCD, no matter how small the cut-out width is horizontally, the frame rate cannot be increased.

When Partial scan mode is used, set Format7, Mode 0.

XCD-SX910CR/X710CR XCD-SX910UV XCD-SX910/X710

Binning Mode

The mode used when the sensitivity is increased and the frame rate is multiplied based on mixing the CCD pixel data, is called the Binning mode. There are two types of binning: 1 × 2 binning when the output image is compressed in the vertical direction only, and 2 × 2 binning when the image is compressed in the horizontal direction also. When binning mode is used, set either Format7 Mode 1 (2 × 2 binning), or Format7 Mode 2 (1 × 2 binning).

The specifications for each model are given below.
