    (the inverse of line rate). This also allows a fixed exposure time, independent of the line rate. In the LQ-201CL the exposure time can be set individually for all four channels.

  • Page 16: Key Functions

    Video output timing Key functions Important note: LQ-201CL has many functions explained in this chapter. In order to use these functions properly and to get proper image, please follow the procedure described below. Setting procedure: 1. Set the shutter and line rate 2.

  • Page 17: Line Rate (Command Lr)

    LQ-201CL 6.2.1 Line rate (Command LR) This function can set the line rate longer than 1L. Accordingly, it is possible to set the camera scan rate with the object running speed or to boost up the sensitivity by setting longer exposure time.

  • Page 18: Een (Exposure Enable) Function

    LQ-201CL 6.2.3 EEN (Exposure Enable) function This function outputs the timing for image accumulation in all operating modes except test pattern output. The output can be through both the 12-pin and Camera Link connectors. The polarity of this output is negative from the 12-pin connector and positive from the Camera Link connector. These polarities cannot be changed.

  • Page 21: Dsnu (Dark Signal Non-Uniformity) Correction

    LQ-201CL Before correction: Non-uniform response from pixel to pixel Multiply Factor < 1 Average Multiply Factor > 1 Fig.15 Conceptual drawing for PRNU correction (1) To correct for PRNU, the camera’s internal correction circuit captures one or several lines of data under non-saturated illuminated conditions which are not more than 80% of maximum (recommend level is half of maximum), and the average across the line is calculated.

  • Page 22: Shading Correction

    LQ-201CL After correction: Flat dark signal response from pixel to pixel Average Fig.18 Conceptual drawing of DSNU correction 6.2.10 Shading correction Shading is caused either by illumination with uneven distribution of light across the surface, or by reductions in the light transmission ratio towards the edges of a lens.

  • Page 23: Lateral Chromatic Aberration

    The range of correction is minus three pixels to plus three pixels. In order to realize this function, the LQ-201CL uses an FIR (finite impulse response) filter for R, B and NIR channels. The filter’s response is determined by a set of 7 types of filter coefficients. The 2048 pixels that make up a line are divided in 16 blocks, with each block having 128 pixels.
  • Page 24 LQ-201CL 2048th Pixel Pixel number in each block: 128 pixels Note: Restrictions for this function In order to adjust properly lateral chromatic aberration, the difference between G and R or B or NIR on right and left sides should be equal. Otherwise, the compensation may not be properly executed.
  • Page 25 LQ-201CL Change name : Instead of Lens 1, 2 and 3, specific names such as 28mm can be displayed. Max. 16 alpha-numeric characters can be used. Left side pixel : Specifies by how many pixels the left edge of the image should be shifted.

    LQ-201CL Fig. 24 Setting example Note: 1) If left side pixel is set at -2 or +2, only Area and 2nd can be configured. 3rd cannot be set. 2) If left side pixel is set at -1 or +1, only Area can be configured.
