CV-A33CL

6. Functions and Operations

In the following the format shown in “7.3. CV-A33CL command list” are used for function commands and parameters.

6.1. Basic functions

The CV-A33CL camera is a progressive scan camera with 10 or 8 bit video output in single channel Camera Link. Programmable partial scan, where the start line and the number of lines can be selected with 1 line increment is also available. There are 4 modes: Normal continuous, and 3 trigger modes: Edge Pre-Select (EPS), Pulse Width Control (PWC) and Auto Trigger. The accumulation is LVAL a-synchronous. In the following some of the functions are shown in details.

6.1.1. CMOS Sensor

The CMOS sensor principle layout is shown. The sensor is an array of active photosensitive

R

pixels. The global shutter is working simultaneously on all pixels. The readout can be random row by row. 4 columns are feed through a 4 to 1 multiplexer to an A/D converter. The digitized row signals are placed in a vertical register by a 1 to 4 multiplexing. From here it is read out with the pixel clock pulses, even if the window of interest has fewer columns. The frame speed depends only of the height of the window, not of the width. Pixel principle and column processing with A/D converting is shown below.

6.1.2. Pixel principle

Each pixel consists of a sensing part, a pixel memory and an amplifier. The function can in short be described. The photo diode and charge capacitor is reset when switch 1 is closed. The signal accumulation starts when sw 1 open. The charge is transferred to the pixel memory capacitor when sw 2 close. The accumulation stop when sw 2 open, and the signal is now temporary stored in the memory capacitor. After

can now be reset. With this construction all pixels will integrate at the same time, (Global shutter). The resulting image is temporary stored in the pixel memory during read out, while a new exposure can be started. All timing is set up in the timing block by an internal serial link.

CV-A33CL

6.1.3. Column Process

The voltage signal from a single pixel is send to the column amplifier trough the 4 to 1 multiplexer. After the S/H circuit, the offset and gain calibrating is perform. A 10 bit A/D converter send the digital pixel signal to the digital horizontal shift register by a 1 to 4 multiplexing. Signals from a single row with 667 pixels are processed in parallel and send to the shift register. Control and timing is done from the timing block. The calibrate command CB = 0 will start an automatic calibrate routine for offset and gain for all 167 A/D converter. It reduces the vertical fix pattern column noise.

6.1.4. CV-A33 CMOS Sensor array

The CMOS sensor total array is 667 (h) x 502 (v). Here the 659 (h) x 494 (v) is active photo sensing pixels. 8 pixels (h) and 8 rows (v) are optical black pixels for internal black level reference. There is an A/D converter for each 4 columns. A 4 to 1 multiplexer feed the signals from 4 columns to a A/D converter. The digital converter output is multiplexed to the 667 x10 bit register.

6.1.6. Window of Interest

If a higher frame rate is wanted, it is possible to change the CMOS sensors sensing area to the window of interest. WS =1 for windows scan. The X,Y start coordinate, the window width and height can be programmed. WX can be in the range 0 to 657 WY can be in the range 0 to 490 WW can be in the range 2 to 659. (WX + WW ≤ 659) WH can be in the range 3 to 493. (WY + WH ≤ 493) The frame rate will not increase if the width WW is reduced. The horizontal shift register need to be read out in its full length. Minimum size for the window of interest is 2 (h) x 3 (v) pixels. Maxim frame rate is 4953 fps. For DVAL timing details for the window of interest, refer to 6.2.5 fig. 17 through 19.

6.1.7. Auto Trigger Window of Interest.

The auto trigger function, TR=3 can be used as sensing device inside the camera field of view. The scanned area is from top of the image, and the height can be programmed with the command AT= --. The accumulation time is equal to the number of LVAL programmed with AT. The minimum height of the window of interest for the auto trigger function is the 3 top lines of the image. The height of the auto trigger window can be programmed in the range AT = 3 to

493. The window is always from the top of image. The read out time is the active number of LVAL + 9 LVAL. Maxim frame rate is 5403 fps given by the 11 LVAL for a minimum window read out. (1 LVAL = 16.825 µsec.) The connected frame grabber should be programmed to sense if objects passing the window. The horizontal position and the signal threshold could be the programmed parameters. If an object passing is detected, a trigger is send to the camera, and a full frame is exposed with the same accumulation time as programmed for AT. The resulting image, a full frame or windows scan, (depending of windows scan setting), is read out to the grabber, and the auto trigger function will start again.

In CV-A33 with LVAL a-synchronous accumulation a new trigger can be input and start a new exposure during the previous frame read out. But the exposure may not be finished before the frame is read out. It makes it possible to have a trigger rate close to the frame rate. The minimum trigger interval should be >(1FVAL + 1 LVAL).

This camera can operate in 4 primary modes. 1 non-triggered, 2 external asynchronous trigger modes and auto trigger mode.

1. Normal continuous Mode. TR=0 Pre-selected exposure. (SM=0, SM=1)

2. Edge Pre-select Mode. TR=1 Pre-selected exposure. (SM=0, SM=1)

3. Pulse Width Control Mode. TR=2 Pulse width controlled exposure.

4. Auto Trigger Mode. TR=3 >3 line window, <5404 fps

In normal continuous mode (TR=0) and edge pre-select mode (TR=1) the shutter time can be selected from the normal 8 fixed steps (SM=0), or it can be selected from the 2 to 493 steps programmable (SM=1). In programmable exposure the actual exposure is 1 LVAL less than the PE value. The trigger pulse width should be >1 LVAL to <3 FVAL. (>16.8 µsec. to <25 msec.)

In pulse width control (TR=2) the trigger pulse width should be >1 LVAL to <237 FVAL. (>16.8 µsec. to <2 sec.)

Windows of interest (WS=1) can be used in normal, edge pre-select and pulse width control mode. (TR=0, TR=1 and TR=2).

6.4.1. Continuous Operation (Non triggered)

Mode settings can be done with RS-232C. Trigger Mode Normal. TR=0. It is for applications where the camera is continuous running without external trigger. The shutter mode can be normal or programmable exposure. (SM=0, SM=1). The shutter will work in all 8 steps up to 1/20,000 second or with the programmable exposure in 2 to 493 steps. In programmable exposure the actual exposure is 1 LVAL less than the PE value. In windows scan (WS=1), shutter times longer than the actual frame time have no meaning. The exposure will be equal the frame time.

To use this mode: Set function: Trigger mode “Normal” TR=0 Shutter mode “Normal” or “Programmable” SM=0, SM=1 “Shutter Speed” SH=0 through 7 “Programmable exposure” PE=2 through 493 “Windows” “Full” or “Windows scan” WS=0, WS=1 Polarity and other functions

Important notes on using this mode.

• The line at the end of the exposure period (SM=0, SM=1) will have a slightly lower signal level. (About 10%). It is caused by the CMOS. (With SH=1/250 the line is seen in the middle of the image).

For timing refer to 6.2.2. and 6.2.3. Fig. 14. and fig 15. For windows scan timing refer to 6.2.5 and fig.17 through fig.19.

6.4.2. Edge Pre-select Mode

The exposure will start 28 µsec. after the trigger leading edge, and it stops and is read out after the shutter time selected. It can be the 8 steps in normal or 2 to 493 steps in programmable. SM=0 or SM=1. In programmable exposure the actual exposure is 1 LVAL less than the PE value. This mode will operate with full window or windows of interest scanning. An EEN pulse will indicate the active accumulation time, and a FVAL pulse indicates that the resulting video is read out.

To use this mode: Set function: Trigger mode “Edge Pre-select” TR=1 Shutter mode “Normal” or “Programmable” SM=0, SM=1 “Shutter Speed” SH=0 through 7 “Programmable exposure” PE=2 through 493 “Windows” “Full” or “Windows scan” WS=0, WS=1 Polarity and other functions Input: Ext. trigger to Camera Link or pin 10 on 12-pin connector.

Important notes on using this mode.

• The duration of the trigger should be >1 LVAL to <3 FVAL. (>16.8 µsec. to <25 msec.)

• A new trigger can be applied before FVAL is low as long as the exposure will be on for

longer than the FVAL high period. Refer to 6.2.4

For timing refer to 6.2.2. and 6.2.3. Fig. 14. and fig 15. For windows scan timing refer to 6.2.5 and fig.17 through fig.19. For LVAL a-synchronous accumulation refer to 6.2.4 and fig 16.

6.4.3. Pulse Width Control Mode

The exposure will start 28 µsec. after the trigger leading edge, and it stops and is read out at the trigger trailing edge. This mode will operate with full window or windows of interest scanning. An EEN pulse will indicate the active accumulation time, and a FVAL pulse indicates that the resulting video is read out.

To use this mode: Set function: Trigger mode “Pulse Width Control” TR=2 “Windows” “Full” or “Windows scan” WS=0, WS=1 Polarity and other functions Input: Ext. trigger to Camera Link or pin 10 on 12-pin connector.

Important notes on using this mode.

• The duration of the trigger should be >1 LVAL to <237 FVAL. (>16.8 µsec. to <2.0sec.) The image quality can be reduced at maximum pulse width.

• A new trigger can be applied before FVAL is low as long as the exposure will be on for longer than the FVAL high period. Refer to 6.2.4

For timing refer to 6.2.2. and 6.2.3. Fig. 14. and fig 15. For windows scan timing refer to 6.2.5 and fig.17 through fig.19. For LVAL a-synchronous accumulation refer to 6.2.4 and fig 16.

6.4.4. Auto trigger Mode

The auto trigger function, TR=3 can be used as sensing device inside the camera field of view. It sense in a programmable window from top of the image. The continuous output is sent to the frame grabber, which PC should be programmed to sense if an object is passing the window. The horizontal position and the signal threshold could be the programmed parameters. If an object passing is detected, a trigger is send to the camera. The resulting image, a full frame or windows scan, (depending of windows scan setting), is read out to the grabber, and the auto trigger function with fast scan of the programmed window will start again.

To use this mode: Set function: Trigger mode “Auto Trigger Mode” TR=3 “Auto Trigger” AT=3 through 493 “Windows” “Full” or “windows scan” WS=0, WS=1 Polarity and other functions

PC and grabber: Detect trigger conditions Send a pulse width control trigger to the camera.

Input: Ext. trigger to Camera Link or pin #10 on 12-pin connector.

Important notes on using this mode.

• The exposure is equal the programmable parameter AT.

• The exposure time is the same for the auto trigger partial scanned frame and the

resulting triggered frame read out.

• The duration of the trigger should be >1 LVAL to < 1 FVAL. (>16.8 µsec. to <8.3 msec.)

• Refer to 6.1.7. Auto Trigger Window of Interest.

• Max auto trigger frame rate is 5403 fps.
