  • Page 33: Exposure Time Control

    DRAFT Operation and Features 3.2 Exposure Time Control The A202 can operate under the control of an external sync signal (ExSync) or can operate in “free-run”. In free-run, the camera generates its own internal control signal and does not require an ExSync signal.

  • Page 34: Recommendations For Controlling Exposure In Exsync Level-Controlled Mode

    DRAFT Operation and Features You can set the camera to operate in one of the ExSync controlled exposure modes using either the Camera Configuration Tool Plus (see Section and the configuration tool’s on-line help) or binary commands (see Section 4.2). With the configuration tool, you use the Exposure Time Control Mode setting in the Exposure group to set the camera for ExSync operation and to select the level-controlled or programmable exposure time control mode.

  • Page 43: Gain And Offset

    DRAFT Operation and Features 3.5 Gain and Offset The major components in the A202 electronics include: a CCD sensor, two VGCs (Variable Gain Controls), ADCs (Analog Digital Converters). When exposed to light, the pixels in the CCD sensor output voltage signals. These voltages are amplified by the VGCs and transferred to the ADCs which convert the voltages to digital output signals.

  • Page 44: Setting The Gain

    DRAFT Operation and Features With binary commands, you must use the Left Side Gain and Right Side Gain binary commands to set the gain and the Left Side Offset and Right Side Offset binary commands to set the offset. 3.5.1 Setting the Gain When the gain is set to default, the sensor’s linear output range directly matches the input voltage range of the ADCs.

  • Page 45: Balancing The Left Side And Right Side Gain

    DRAFT Operation and Features In normal operation, gain settings lower than 288 (0x0120) should not be used. With gain settings lower than 288, the sensor output signal mapped to the input of the ADCs will not be linear. 3.5.2 Balancing the Left Side and Right Side Gain As described on page 3-13, gain alignment between the channels, combined with offset alignment, is important to maintain uniform output data with minimal gray value differences between the left side and the right side of the image.

  • Page 46: Balancing Gain Settings When Using Binary Commands

    DRAFT Operation and Features 3.5.2.1 Balancing Gain Settings When Using Binary Commands The left side gain is set using the Left Side Gain binary command (see Section 4.2.4.10) and the right side gain is set using the Right Side Gain binary command (see Section 4.2.4.12). Each gain setting can be programmed on a decimal scale that ranges from 0 to 569 (0x0000 to 0x0239), however, values lower than 288 (0x0120) should not be used.
  • Page 47 DRAFT Operation and Features 4. Enter the decimal value for the left side reference gain (RG ) and the decimal value for the desired gain (G) into the formula below: Where: ---------------------------------- - 20 log 8.15 – 658 RG – G = Desired gain in dB ≤...

  • Page 48: Setting The Offset

    DRAFT Operation and Features 6. Use the same method as shown in steps 3, 4, and 5 to calculate the right side gain setting. For our example, the result would be 446. 7. Convert the results to hexadecimal: Left Side Gain Setting of 443 decimal = 0x01BB Right Side Gain Setting of 446 decimal = 0x01BE 8.

  • Page 49: Balancing The Left Side And Right Side Offset

    DRAFT Operation and Features 3.5.4 Balancing the Left Side and Right Side Offset As described on page 3-13, offset alignment between the channels, combined with gain alignment, is important to maintain uniform output data with minimal gray value differences between the left side and the right side of the image. In some applications, multiple cameras are used, for example, when two area scan cameras are used next to each other to form one large image.
  • Page 50 DRAFT Operation and Features Sample Calculation Using the Reference Offset Values Assume that you are working with an A202 , that you have selected an 8 bit output mode, that you want an offset of 5, and that you want to keep the left side and the right side of the image in balance.

Section 3.6.1 describes how digital shift works when the camera is operating in 10 bit output mode...

  • Page 53: Digital Shift In 8 Bit Output Modes

    DRAFT Operation and Features Shift Twice When the camera is set to shift twice, the output from the camera will include bit 7 through bit 0 from each ADC along with two zeros as LSBs. The result of shifting twice is that the output of the camera is effectively multiplied by four.
  • Page 54 DRAFT Operation and Features Shift Once When the camera is set to shift once, the output from the camera will include bit 8 through bit 1 from each ADC. The result of shifting once is that the output of the camera is effectively doubled.

  • Page 55: Precautions When Using Digital Shift

    DRAFT Operation and Features 3.6.3 Precautions When Using Digital Shift There are several checks and precautions that you must follow before using the digital shift feature. The checks and precautions differ depending on whether you will be using the camera in 10 bit output mode or in 8 bit output mode.

    DRAFT Operation and Features 3.7 Area of Interest (AOI) The area of interest (AOI) feature allows you to specify a portion of the CCD array and during operation, only the pixel information from the lines included in the AOI is transferred out of the camera.

  • Page 57: Aoi Setup Guidelines

    DRAFT Operation and Features 3.7.1 AOI Setup Guidelines When setting up the area of interest, several guidelines must be followed. The setup rules are listed below. • The starting line must be an odd numbered line and the starting column must be an odd num- bered column.

  • Page 58: Changes To The Pixel Timing And Output With Aoi

    DRAFT Operation and Features 3.7.3 Changes to the Pixel Timing and Output with AOI When the AOI feature is being used, frame valid will rise at the normal time, however, there will be a delay between the rise of frame valid and the rise of the first line valid while the camera discards data from the lines below the AOI.

  • Page 60: Binning

    DRAFT Operation and Features 3.8 Binning Binning is available on A202 monochrome cameras. Binning increases the camera’s sensitivity to light by summing the charges from adjacent pixels into one pixel. There are three types of binning available: horizontal binning, vertical binning, and full binning. With horizontal binning, pairs of adjacent pixels in each line are summed (see Figure 3-14).

  • Page 61: Changes To The Maximum Frame Rate With Binning

    DRAFT Operation and Features 3.8.1 Changes to the Maximum Frame Rate with Binning When vertical binning or full binning is used, the camera’s maximum allowed frame rate increases. The maximum allowed frame rate can be calculated using the following formula: 1000000 µs Maximum Frames per Second -----------------------------------------------------------------------------------------------------------------------------------...

  • Page 62: Color Creation In The A202Kc

    DRAFT Operation and Features 3.10 Color Creation in the A202kc The CCD sensor used in the A202 is equipped with an additive color separation filter known as a Bayer filter.

    DRAFT Operation and Features 3.11.2 Test Image Two The basic pattern of test image two is similar to test image one. However, with test image two, the pattern of the image moves up by one pixel each time the ExSync signal cycles. When you view the output of a camera that is set for test image two, the pattern should appear to be gradually moving up the screen.
