6. Series 3 1 Operation and Features Basic Operation and Features Functional Description BASLER L100k line scan cameras employ a CCD sensor chip which provides features such as electronic exposure time control and anti blooming Exposure time is normally controlled via an external trigger ExSync signal The ExSync signal facilitates periodic or non periodic pixel readout When exposure is controlled by an ExSync signal exposure time can be either edge controlled level controlled or programmable In edge controlled mode charge is accumulated over the entire period of the ExSync signal and a rising edge of ExSync triggers the readout of accumulated charges from the sensor elements to the CCD shift registers In level controlled mode charge is accumulated when the ExSync signal is low and a rising edge of ExSync triggers the readout In programmable mode exposure time can be programmed to a predetermined time period In this case exposure begins on the rising edge of ExSync and accumulated charges are read out when the programmed exposure time ends A free run mode that allows the camera to operate without an ExSync signal is also available In free run mode the camera generates its own internal control signal and the internal signal is used to control exposure and charge read out When operating in free run the camera outputs lines continuously At readout accumulated charges are transported from the light sensitive sensor ele

11. Camera Interface Operation in Dual 10 Bit or Dual 8 Bit Output Mode L103k and L104k only In Dual 10 Bit mode the pixel clock operates at 20 MHz for the L103k and 31 25 MHz for the L104k On each clock cycle the camera transmits a line valid bit a data valid bit and ten bits of data for two pixels The assignment of the bits is shown in Table 2 3 The pixel clock is used to time data sampling and transmission As shown in Figures 2 9 and 2 10 the camera samples and transmits data on each falling edge of the pixel clock The line valid bit indicates that a valid line is being transmitted Pixel data is only valid when the line valid bit is high The data valid bit is not used in this mode It is always high and should be ignored Operation in Dual 8 Bit mode is similar to Dual 10 Bit mode except that the two least significant bits output from each ADC are dropped and only 8 bits of data per pixel is transmitted The data sequence outlined below along with Figures 2 9 and 2 10 describe what is happening at the inputs to the Camera Link transmitter in the camera Note that the timing used for sampling the data at the Camera Link receiver in the frame grabber varies from device to device On some receivers data must be sam pled on the rising edge of the pixel clock receive clock and on others it must be sampled on the falling edge Also some devices are available which allow you to select either rising edge or falling edge samp

Binary Commands to Work With Shading Correction When using binary commands to create and upload a shading table and to enable the shading correction feature follow the instructions given in Sections 3 6 3 1 through 3 6 3 3 3 6 3 1 Creating a Shading Correction Table When shading correction is active on the LIOOk camera each pixel value is multiplied by a correction factor and the corrected pixel values are transferred out of the camera There is an individual correction factor for each of the sensor s pixels that is there are 1024 correction factors for cameras with a 1024 pixel sensor or 2048 for cameras with a 2048 pixel sensor The correction factors are multipliers that are applied to the pixels in each captured line to make them better represent what they would be if no shading was present The correction factors are determined by capturing an image of a uniform target and then for each pixel calculating the multiplier that would make the pixel value equal to the lightest pixel in the image Lightest pixel Correction factor Current pixel Correction factors are floating point numbers Since floating point numbers cannot be written into the camera each correction factor must be converted into an integer value that represents the correction factor Here is the formula that is used for conversion Correction value 256 Correction factor 256 The range of possible correction factors is 1 to 1 996 where 1 converts to a
