1. General CV-L107CL is a 3CCD line scan camera using three 2048 pixel line sensors mounted on a prism, for the R, G and B channels. It operates with a 40 MHz pixel clock, resulting in a maximum line rate of 19 047 lines per second.

11,24 12,25 13,26 Shield The CV-L107CL follows the Camera Link standard in all respects. Please refer to the Camera Link version 1.1 specifications for detailed information on bit assignments of 24-bit RGB and 30-bit bit output. 5.3. Input and output circuits 5.3.1.
CV-L107CL 5.3.2. EEN / XEEN output (Exposure ENable) This output corresponds to the exposure (accumulation) time of the camera. It works together with all operation modes. It is, however, not active when the test pattern function is enabled. The EEN signal is available at the Camera Link connector and at the 12-pin Hirose connector at the same time.
(the inverse of line rate). This also allows a fixed exposure time, independent of the line rate. In the CV-L107CL the exposure time can be set individually for all three channels.
CV-L107CL 6.2. Pixel Gain (flat-field) correction (PRNU correction) Pixel Response Non-Uniformity is, as the name expresses, a non-uniformity of the response of each individual pixel. This means that for a fixed light level each pixel will have a slightly different output level (response).
CV-L107CL After correction: Flat dark signal response from pixel to pixel Average 6.4. Shading correction Shading is caused either by illumination with uneven distribution of light across the surface, or by vignetting towards the edges of a lens. The shading correction incorporated in the camera will compensate for this effect by as much as 20% of the brightest signal.
CV-L107CL 6.6. Operation modes The CV-L107 provides three basic modes of operation: No-shutter, Shutter-Select and Pulse Width Control (PWC). The Shutter-Select and PWC modes also allow the user to set the exposure time independently from the scan rate, by making use of the electronic shutter (the Exposure Control Gate of the CCD sensor).
CV-L107CL 6.6.1. No-Shutter mode with Internal line rate generator In this mode the camera does not accept an external trigger signal, as the line rate is generated from an internal clock (user programmable, command LR). The exposure time is directly proportional to the line rate (T = 1/line rate).
CV-L107CL 6.6.2. No-Shutter mode with External Trigger In this mode, the exposure time is directly proportional to the line rate. The line rate is generated externally by a trigger signal. This mode is used when an external trigger signal available, e.g. from an encoder, and the scan rate can be controlled by this signal.
CV-L107CL 6.6.3. Shutter-Select mode with Internal line rate generator This mode allows the user to have full control of the line rate and the exposure time individually, by programming separate timing generators. Subsequently the camera does not accept an external trigger signal in this mode.
CV-L107CL 6.6.4. Shutter-Select mode with External trigger This mode allows the user to have full control of the exposure time, by programming a timing generator, while the line rate is controlled by an external trigger signal. The camera can accept an external trigger through the Camera Link connector or though the 12-pin Hirose connector.
CV-L107CL 6.6.5. Pulse Width Control (PWC) mode In this mode, the user has full control of both the line rate and the exposure time of each line via the External Trigger input. At the falling edge of the External Trigger signal, the exposure is initiated, and at the rising edge the exposure is terminated and read out.
6.6.6. Auto Reset mode In this mode, when the interval of the trigger pulse is more than 55ms, the CV-L107CL automatically returns to continuous operation with the line rate of 52.5μs . At this time, DVAL,EEN and Video OUTPUT are disable in order to prohibit charge due to dark current to add up in the sensor in standby periods.

CV-L107CL Important Note: When color temperature of used illumination exceeds the range of adjustment, proper white balance may not be obtained. The data can be stored in camera memory for use at next start up. This function can work on External trigger mode.
0LSB to 64 (16) LSB. The number in parenthesis is valid for 24-bit output. The CV-L107CL has an automatic black level clamp function. This circuit is an analog circuit and after the signal level of dummy pixels is clamped at the constant level, it is digitized and the OB level is clamped at 32LSB(8LSB) in the digital clamp circuit.
CV-L107CL 8.15 Command NK – Knee function enable/disable This command turns the knee function on or off. The sensor output is digitized to 4095LSB of dynamic range. When input (CCD output) and output (Camera link data) relations is set at linear, the output is clipped at 1023 LSB and the details above 1023 are not visible.
Command NOSR – Noise reduction This function deletes the noise component of less than 16LSB composed in the signal. This circuit used in the CV-L107CL minimizes the deterioration of the spatial frequency. The improvement depends on the object and it will be approx. 3dB.
CV-L107CL Here, Repetition period is the setting line rate or trigger interval T1 is the setting value for the exposure time. 8.23 Command PEG – Programmable exposure – Green This command allows individual setting of the exposure time of the Green channel. It is only valid for the Shutter-Select mode (see chapter 6.2)
CV-L107CL Settings: 0 = off (Bypass) 1 = Factory setting (default) 2 = User area Associated functions: Commands PGR, SDR and SDS 8.28 Command SDR – Run shading correction This function initiates automatic shading correction, and stores the result to the user area.
CV-L107CL Important Note: For this function, no reference value is stored in the camera. Operating procedure for individual R, G and B channel shadings correction: 1. Before making adjustment, it is required approximately 30 minutes warming up. 2. Make sure the output signal is not saturated (80% of full output is recommended) 3.
CV-L107CL 8.32 Command TP – Trigger polarity Settings: 0=Active Low (factory default) 1=Active High 8.33 Command TR – Trigger Mode Selects the trigger mode of the camera. Depending on the mode used, it allows the scan rate to either be programmed by an internal timing generator or by and external trigger pulse.
8.37 Serial communication The CV-L107CL can communicate by serial communication via the Camera Link connector or via RS232C in the 12-pin Hirose connector. The Baud Rate is fixed at 9600 bps. Switch SW1 at the rear panel of the camera is used to select which way the serial communication is set up.
