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 19: Gain Control
LQ-201CL 6.2.5 Gain control The LQ-400CL has two ways of setting gain - one for master mode and the other for individual mode. Each setting also has two analog gain modes - one is GAIN LOW and the other is GAIN HIGH. Gain Low is the default output setting. -

Page 21: Prnu (Pixel Response Non-Uniformity ) Correction
LQ-201CL 6.2.7 PRNU (Pixel Response Non-Uniformity ) correction PRNU (Pixel Response Non-Uniformity) is, as the name implies, 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). -
Page 22: Dsnu (Dark Signal Non-Uniformity) Correction
LQ-201CL 6.2.8 DSNU (Dark Signal Non-Uniformity) correction DSNU (Dark Signal Non-Uniformity) is, as the name implies, a non-uniformity of offset level of each pixel, which is not dependent on the incoming light. Before correction: dark signal non-uniformity from pixel to pixel... - Page 23 LQ-201CL Flat shading correction (SDR=0): Flat shading correction compensates red, blue, green and NIR signals to be flat output. The range of compensation is within plus-or-minus 20% as compared the brightest signal level. It may not compensate enough according to the lenses and/or lighting in use.
-
Page 24: 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 25 LQ-201CL Fig. 22 Setting screen for lateral chromatic aberration Setting procedure: Please use the following steps. 1. Chromatic Aberration Enable 2. Select Lens 1, 2 or 3 3. Set the left side pixel 4. Set the area 5. Set the second block pixel 6.
