CV-L108CL298.19 Command NOSR – Noise reductionThis function deletes the noise component of less than 16LSB composed in the signal.This circuit used in the CV-L107CL minimizes the deterioration of the spatial frequency.The improvement depends on the object and it will be approx. 3dB.Settings 0=ON, 1=OFF8.20 Command PBC – Enable pixel black (FPN) correctionThis command enables (or disables) the “pixel black level” correction function, whichcompensates for Dark Signal Non Uniformity / Fixed Pattern Noise (DSNU / FPN) forindividual pixels.Settings: 0 = Off1 = Factory setting2 = user areaAssociated functions: Command PBRApplicable modes: All8.21 Command PBR – Run pixel black correction and store to user areaThis command initiates the “pixel black level” correction function, and stores the settingsin the user area. When this function is activated, lens must be capped.Settings: 0 = Run this functionAssociated functions: Command PBC must be set to 2Important note: This function requires that no light reaches the image sensors. The lens must thereforebe covered by a lens cap, or put the F-mount protective cover on the camera, whenexecuting this function. As the black level is influenced by the exposure time (especially for long exposure time,at slow scan rates) it is recommended to perform the pixel black correction at theexposure time and line rate at which the camera will be operated.8.22 Command PER – Programmable exposure – RedThis command allows individual setting of the exposure time of the Red channel. It is onlyvalid for the Shutter-Select mode (see chapter 6.2)Settings: 2 to 577536, 50 ns to 14.438 ms in 25ns stepsAssociated functions: EI (R and G exposure interlocked with G)The actual Exposure time (ns) is calculated as follows:Texp = 25ns x (Repetition period ([Parameter]) – (T1 ([Parameter]) +21 [Parameter]) )8.23 Command PEG – Programmable exposure – GreenThis command allows individual setting of the exposure time of the Green channel. It isonly valid for the Shutter-Select mode (see chapter 6.2)Settings: 2 to 577536, 50 ns to 14.438 ms in 25ns stepsAssociated functions: EI (R and G exposure interlocked with G)
