Overview Overview The XCD-V50CR/V50 with its 1/3-type PS IT CCD is industrial-use digital video camera module. Utilizing an IEEE 1394b-2002 digital interface, transfer rates as high as 800 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 ratio conversion during image processing.
Overview System Components The XCD-V50CR/V50 Video Camera Module system comprises the following components. Video Camera Module XCD-V50CR/V50 Host Adapter Card (Commercially available) XCD-V50CR XCD-V50 IEEE1394b Cable (9 pin-9 pin 4.

Functions Functions Gain Trigger Shutter Manual Gain setting is available with this camera. The variable range extends from 0 to 18 dB, and the unit is designed so that the gain can be subdivided and set to any of 512 steps. At the factory default setting, the gain is set to 0 dB. Shutter This camera allows Manual Shutter setting. The relationship between the parameter and the exposure time is given by the following formulas. Where P = Parameter (001h ~ C7ch) E = Exposure time (µs) E = (Int (P × 0.
Functions 16-bit Mode White Balance The camera supports 16-bit Black & white (Monochrome) mode, but because the output of the AD converter is 14-bit, only the least significant 14 bits of the 16 bits will handle data. The upper 2 bits will be filled with zeros. (XCD-V50CR only) You can adjust the R and B gain with respect to G. Shoot a white object and adjust the two gains to standardize the signal levels of R, G, and B.
Control Control Camera Command Status Register This camera complies with IIDC 1394-based Digital Camera Specification, Version 1.31 (hereinafter referred to as IIDC v1.31). The standards document can be purchased from 1394TA (the 1394 Trade Association). Because it is very helpful in understanding the explanations in this Technical Manual, we recommend that you purchase a copy of IIDC v1.31. Memory Map 1394 devices have a 64-bit address space.

Control Control Base Address Every register address is decided based on the base address found in the CommandRegsBase field of ConfigROM. F0F00000h is the control base address on this camera. Inquiring Supported Video Modes First, we will find out what video formats are supported. Address Data F0F00100h 80000000h We find that Format0 is supported. Next, for each format, we will find out which video modes are supported.
Control Video Mode Settings Select the video mode you want to use from the tables, and make the required settings. As example, the register setting for Format0, Mode5, and a frame rate of 60 fps is shown. In addition, an isochronous transfer speed of 800 Mbps, and isochronous channel 0 are used in this example. When you use the camera via the 1394a interface, set the isochronous transfer speed to 400 Mbps. When multiple cameras are used simultaneously, set different isochronous channels for each one.
Control Feature Controls This camera supports the following features. Shutter Controls the exposure time. Can be controlled by both relative control values from 1/100000 of a second to 1/15s, allocated from 1 to 3196. Gain Can be changed to 0 to 18 dB, subdivided in 512 steps. Trigger Sets external trigger mode. Trigger Mode 0 and 1 are available. Software Trigger Mode in which triggers can be output by software. The XCD-V50CR supports the following additional features.
Control Shutter (exposure time) control Address Data F0F0081C 82000ddd Address Sets Shutter manually. Gain control F0F0080C Data 82bbbrrr Sets R and B Gain. “bbb” sets B Gain, “rrr” sets R Gain.

Appendix Appendix Notes on the Camera Operations When using Trigger mode When this camera is set to accept a trigger at the fastest possible timing, it can accept overlap of the next trigger signal in the midst of video transmission. For this reason, a trigger inhibition period is not available. Thus, if a trigger signal is input before the CCD can change to the state where it can accept exposures, multiple exposures can occur, and it cannot capture the correct image.
