Before using USB 3.0 camera

EMVA 1288

With regard to signal to noise ratio in this manual, specifications measured by EMVA 1288 are used together with specifications by a traditional measurement method. EMVA 1288 is a more complete measurement that considers multiple noise sources, including random noise, pattern noise, and shading. Additionally, EMVA 1288 incorporates temporal variances in pixel output by capturing 100 frames of data and computing the RMS variations over the captured frames. Because of the comprehensive nature of the noise analysis and the additional consideration for RMS variances over time, EMVA 1288 SNR measurements are inherently lower than the traditional SNR measurements given by manufacturers. However, the comprehensive nature combined with rigid test parameters, means that all manufacturers are measuring their products equally and EMVA 1288 tested parameters can be compared among different manufacturers’ products. In order to learn more about EMVA 1288, please visit http://www.emva.org

Interface

The EL-2800-USB employs a USB 3.0 interface and is in the process of being certified for compliance with the USB3 Vision standard. USB3 Vision is a new standard interface for machine vision applications being developed and managed by the AIA (Automated Imaging Association). USB3 Vision uses USB 3.0 ports that will soon be standard on most PCs (with Windows 7 service pack and Windows 8 native support expected soon). Components from different manufacturers will easily communicate with each other.

USB3 Vision also supports the GenICamTM standard which is managed by the EMVA (European Machine Vision Association). The purpose of the GenICam standard is to provide a common program interface for various machine vision cameras. By using GenICam, cameras from different manufacturers can seamlessly connect in one platform.

The maximum transfer speed of USB 3.0 is specified at 5.0 Gbps, however effective bandwidth is reduced by a number of factors including pixel format conversions and the physical interface components used. The USB3 Vision standard specifies a bandwidth of 2.8 Gbps or greater. Maximum cable length for passive cables is five meters, but this can be made longer using active cables.

As for the USB connector, EL-2800-USB uses a Micro B connector which complies with USB 3.0. This connector has an additional 5-pin plug “stacked” on the side of a standard USB 2.0 Micro B connector. However, USB 2.0 cannot be used with the EL-2800-USB.

Power supply

Although the USB 3.0 interface is capable of supporting both data and power, EL-2800-USB requires both +5V and +12V. A separate power supply unit must be connected to the 12-pin connector for providing +12V.

Computer used for EL-2800-USB series

It is necessary to use a PC equipped with a USB 3.0 interface. It is also recommended to use a PC equipped with slots of better than PC Express 2.0 x 8. Please note that the EL-2800-USB may not work properly depending on the chipset used in the PC.

1. General

The EL-2800M-USB and EL-2800C-USB are new cameras in JAI’s Elite Series. They provide high picture quality, such as high sensitivity and low noise, suitable for machine vision applications. The EL-2800M-USB is a monochrome progressive scan CCD camera and the EL-2800C-USB is the equivalent Bayer mosaic progressive scan CCD camera. Both are equipped with a 2/3 inch CCD sensor offering 2.83 million pixels resolution and a 4:3 aspect ratio. They provide 54.6 frames per second for continuous scanning with 1920 x 1440 full pixel resolution for both monochrome and raw Bayer output. 8-bit, 10-bit, or 12-bit output can be selected for both monochrome and Bayer outputs.

The new cameras feature a USB 3.0 interface. A full pixel readout, partial scan readout, or binning mode (monochrome only) can be selected depending on the application.

EL-2800M-USB and EL-2800C-USB have various comprehensive functions needed for automated optical inspection applications, such as solid state device inspection or material surface inspection. They incorporate video processing functions such as a look-up table, shading compensation, and blemish compensation in addition to fundamental functions such as trigger, exposure setting and video level control.

As a common Elite Series feature, a new connector for lens control is employed. EL-2800M-USB and EL-2800C-USB support P-iris and motor-driven lenses as standard lens control capabilities. Factory options are available to configure this connector to support DC iris systems as well as provide a video iris output signal, or to provide additional TTL IN and OUT lines.

5.6 Pulse Generator

The EL-2800-USB has a frequency divider using the internal pixel clock as the basic clock and two pulse generators. In each Pulse Generator, various Clear settings are connected to GPIO. The following shows Pulse Generator default settings.

Table - 10 Pulse Generator default settings

5.6.1 Clock Pre-scaler

Clock pre-scaler (Divide Value) can set the dividing value of the frequency divider (12-bit

length) and the pixel clock is used for this. Two built-in pulse generators work by the same clock. In the EL-2800-USB, the internal pixel clock is 54 MHz.

5.6.2 Pulse Generator Selector

This is where you select one of the 2 pulse generators in order to set or modify its parameters.

Note:When Pulse Generator Repeat Count is set to “0”, the camera is operating in Free Running mode.

However, based on the above default settings (Length=1, Start Point=0 and End Point=1), Pulse Generator stops at High output. Therefore, if Start Point=0 and End Point=1 are configured, Length should be “2” as the minimum active width.

5.6.3 Pulse Generator Length

Set the counter up value (number of clocks, refer to Table 12) for the selected pulse generator. If Repeat Count value is “0”, and if Pulse Generator Clear signal is not input, the pulse generator generates the pulse repeatedly until reaching this counter up value.

5.6.4 Pulse Generator Start Point

Set the active output start count value for the selected pulse generator. However, please note that a maximum 1 clock jitter for the clock which is divided in the clock pre-scaler can occur.

5.6.5 Pulse Generator End Point

Set the active output ending count value for the selected pulse generator.

5.6.6 Pulse Generator Repeat Count

Set the repeating number of the pulse for the selected pulse generator. After Trigger Clear signal is input, the pulse generator starts the count set in Repeat Count. Accordingly, an active pulse which has a start point and end point can be output repeatedly. However, if Repeat Count is set to “0”, it works as a free-running counter.

5.6.7 Pulse Generator Clear Activation

Set the clear conditions of clear count pulse for the selected pulse generator.

5.6.8 Pulse Generator Clear Sync Mode

Set the count clear method for the selected pulse generator.

In Async Mode, if the clear signal is input during the length setting value, the counter will stop counting according to the clear signal input. In Sync Mode, if the clear signal is input during the length setting value, the counter will continue to count until the end of the length setting value and then clear the count.

Both modes clear the repeat count when the counter is cleared.

7. Operating modes

7.1. Acquisition control

7.1.1 Acqusition mode

In the EL-2800M-USB and EL-2800C-USB, the following three acquisition modes are available.

Single frame : One frame can be output by AcqusitionStart command Multi frames : The number of frames which is specified in Acquistion Frame Count, are output by AcquisitionStart command Continuous : Images are continuously output by AcquisitionStart command until AcqusitionStop command is input.

7.1.1.1 Single Frame

In single frame mode, executing the AcquisitionStart command causes one frame to be captured. After one frame is captured, this operation is automatically stopped. In order to restart the capture, it is necessary to input the AcquisitionStart command again. BlockID is not reset until AcquisitionStop is input and is incremented when the AcquisitionStart command is called. In the case of PIV operation, 2 frames are captured instead of one frame.

◆ Normal single frame operation

1) AcquisitionStart command is input

2) AcquisitionActive becomes “TRUE” (accepts capture)

3) 1 frame is output

4) AcquisitionActive becomes “FALSE” (stop capturing)

◆ Forcing acquisition to stop

While AcquisitionActive is “TRUE”, if AcquisitionStop or AcquisitionAbort is initiated, AcquisitionActive becomes “FALSE” (stop capturing). However, if AcqusitionStop command is initiated during image output period, AcqusitionActive becomes “FALSE” (stop capturing) after image output is completed.

7.1.1.2 MultiFrame

In this mode, the AcquisitionStart command captures the number of frames which are specified by AcquisitionFrameCount.

◆ Normal multi-frame operation

1) AcquisitionStart command is input

2) AcquisitionTriggerWait becomes effective

3) AcquisitionActive becomes “TRUE”(accepts capture)

4) Output N frames as specified by AcquisitionFrameCount

5) AcquisitionActive becomes “FALSE”. Then the output stops. (See the following diagram)

Note: This drawing shows if the trigger is OFF. If the trigger is ON, FrameActive turns to True at a different AcquisitionActive timing.

◆ Forcing acquisition to stop

While AcquisitionActive is “TRUE”, if AcquisitionStop or AcquisitionAbort is

initiated, AcquisitionActive becomes “FALSE” (stop capturing). Once the operation is set to “FALSE”, the internal FrameCount is reset.

However, if AcqusitionStop command is initiated during image output period, AcqusitionActive becomes “FALSE” (stop capturing) after image output is completed. Once, AcqusitionActive becomes “FALSE”, the internal count is reset.

 Acqusition Frame Count can be set in the range of 1 to 65535 (16-bit). The setting step

is 1 frame. In PIV mode, Acquisition Frame Count can be set in the range of 2 to 65535. The setting for PIV mode is 2 frames per step.

7.1.1.3 Continuous mode

In this mode, when the AcquisitionStart command is set, the image is continuously output at the current frame rate. This is the default setting for the EL-2800M-USB and EL-2800C-USB.

1) AcquisitionStart command is input

2) AcquisitionTriggerWait becomes effective

3) AcquisitionActive becomes “TRUE”

4) Images begin outputting continuously

5) AcquisitionStop command is sent

6) AcquisitionActive becomes “FALSE”. At this moment, the output stops.

However, if AcqusitionStop command is initiated during image output period, AcqusitionActive becomes “FALSE” (stop capturing) after image output is completed.

7.1.3 Acquisition frame rate

With Trigger OFF (free-running operation), the default frame rate of the camera is based on the specified ROI. However, it is possible to set a longer acquisition period than the time required to read out all pixels in the area set by the ROI command. This is done by entering a value in the AcquisitionFrameRate control corresponding to the acquisition frame frequency.

The setting range is:

Shortest

Longest

The reciprocal of the time

required to read out all

pixels in the area set by ROI

The reciprocal of the time to

transmit one frame data

0.125 Hz (fps)

Note:

1. If the trigger is set to ON, this function is not available.

2. The value for setting is Frame Frequency.

3. If the setting value is less than the minimum period corresponding to the default frame rate, this setting is ignored and camera operates at the minimum period.

Self-running (Trigger OFF) works under the following conditions. Exposure Mode : OFF Exposure Mode : Timed and Frame Start OFF Exposure Mode : Trigger Width and Frame Start OFF.

7.1.3 Frame rate calculation formula

a) If V Bininng Off and Sensor Geometry 1X2-2YE

Frame_Rate (Hz) = 1000000/〔［ Height/2 + {(720-(Height/2)-1)/4} + 26 ］×24.574 〕

b) If V Bininng On and Sensor Geometry 1X2-2YE

Frame Rate (fps) = 100000/〔［ (Height/2) + {(360-(Height/2)-1)/2} + 17 ］×29.296 〕

c) If V Bininng Off and Sensor Geometry 1X-1Y

Frame_Rate (Hz) =

1000000/【〔 Height + {(OffsetY-1)/7} + [{1440-(OffestY + Height)}/15] + 47 〕×42.519】

d) If V Bininng On and Sensor Geometry 1X-1Y

Frame Rate (fps) = 1000000/【〔 (Height/2)+ {(OffsetY-1)/4} + [{720-(OffsetY + (Height/2))}/8] +34 ×47.259】

Note: In this formula, the calculation results underlined must be rounded up.

7.2. Exposure settings

7.2.1 Exposure Mode

The exposure mode can be selected from the following three ways.

Table15. Exposure mode

Exposure Mode setting

Exposure operation

OFF

No exposure control (free-running operation)

Timed

Exposure operation at the value set in Exposure Time. Setting value is usec unit.

・If Trigger Mode setting is OFF, the camera is in free-running operation. ・If Trigger Mode setting is ON, the exposure operation depends on the setting of

Trigger Option.

Trigger Width

The exposure is controlled by the pulse width of the external trigger. ・Trigger Mode is forced to ON.

For trigger operation, Exposure Mode must be set to something other than OFF and Trigger Mode of Frame Start must be ON. If Exposure Mode is set at Timed, the exposure operation can be selected as follows by setting Trigger Option

7.7. RCT mode

Until the trigger is input, the camera operates continuously and the video signal for the auto-iris lens is output. At this moment, the video signal, FVAL and LVAL are output but DVAL is not output. When the trigger is input, the fast dump is activated to read out the electronic charge very quickly, after which the accumulation and the readout are performed. When the accumulated signal against the trigger is read out, FVAL, LVAL and DVAL are output too.

Primary settings to use this mode

7.8. PIV (Particle Image Velocimetry)

The Particle Image Velocimetry mode can be used in applications where 2 images need to be taken with a very short time interval. It can only be used with strobe flash as illumination. The first accumulation time is 10 sec to 2 sec. Then, the second exposure will be taken. The accumulation is LVAL asynchronous. The first strobe is activated during the first exposure duration and the second strobe is pulsed while the first frame is being read out. In this way, two strobe flashes generate two video outputs.
