1. 9 The minimum recommended exposure time is 20 us The exposure time must be less than the line period BASLER L100 series 3 3 Operation and Features 3 4 3 4 Gain and Offset The major components in the camera electronics include a CCD sensor two amplifiers and two ADCs Analog to Digital Converters The pixels in the CCD sensor output voltage signals when they are exposed to light These voltages are amplified by the amplifiers and converted to digital output signals by the ADCs Two parameters gain and offset are associated with each amplifier As shown in Figure 3 6 increasing or decreasing the gain increases or decreases the amplitude of the signal that is input to the ADC As Figure 3 7 shows increasing or decreasing the offset moves the signal up or down the mea surement scale but does not change the signal amplitude The factory default gain and offset are set so that with opti mal lighting see Section 4 2 8 and exposure the linear output range of the CCD sensor maps to the input range of the ADC Under these conditions black will produce a gray value of 1 from the ADC and white will produce a gray value of 254 If your application does not result in an output of 1 with black and 254 with white you should attempt to achieve these results by varying illumination and exposure rather than adjusting the gain Increased gain results in in creased noise and is not recommended Internally L100 c2.

3. 3 3 Exposure Time Control Modes The camera can be programmed to function in three basic exposure time control modes edge controlled level controlled or programmable In these modes an ExSync signal is used to control exposure time and line read out Note that exposure time may vary by 2 Pclk because ExSync must synchronize internally with the pixel clock n the edge controlled mode charge is accumulated over the full line period The falling edge of ExSync is irrelevant The line is read out and transferred with the rising edge of ExSync See Figure 3 3 exposure time line period Figure 3 3 Exposure Time in Edge controlled Mode n the level controlled mode the exposure time of a line being read out is determined by the time between the rising edge and the preceding falling edge of ExSync Charge is only accu mulated when ExSync is low The line is read out and transferred with the rising edge of ExSync See Figure 3 4 line period exposure time EXSYNC line read out Figure 3 4 Exposure Time in Level controlled Mode n the programmable mode the rising edge of ExSync triggers exposure for a time period pro grammed via the serial interface The line is read out and transferred subsequent to the pro grammed time period The falling edge of ExSync is irrelevant See Figure 3 5 line period programmed exposure time d N line read out Figure 3 5 Exposure Time in Programmable Mode
