13. Each feature has one or more CSRs associated with it The fields within a feature s CSR s are used to control how the feature operates By using binary write commands to write to fields within a feature s CSR s you can change the parameter settings for the feature By using binary read commands you can determine the current setting for the parameters and get information about the feature s status The address for any field within a register is equal to the register base address plus the offset for the field Look at the Video Data Output Mode CSR on page 151 as an example The Mode field of this register has an address of 0x1701 the base address of 0x1700 plus the offset of 0x0001 By writing a value to this address you can set the video data output mode By reading the value at this address you can determine the current output mode setting The Video Data Output Mode CSR is a simple CSR with only two fields Most of the other feature CSRs have several read write fields that let you set the parameters associated with the feature They may also have read only fields that contain information about the minimum and maximum allowed setting for each parameter Section 7 2 2 2 on page 145 lists the feature CSRs in the camera and shows detailed information about the use of each field within the register 7 2 2 1 Raw Value Fields vs Absolute Value Fields As you look through the descriptions of the feature CSRs you will notice tha

If you do this the pixel values used to calculate the PRNU correction values will be corrected for DSNU For this option to work correctly you must have already generated DSNU values before you generate the PRNU values 7 Signal the camera to generate a set of PRNU values a You can start the generation of a set of PRNU values with the Camera Configuration Tool Plus see Section 7 1 on page 134 With the CCT set the value of the Generate parameter in the DSNU amp PRNU Shading Correction parameters group to Generate PRNU Values or to Generate PRNU Values with DSNU b You can also start the generation of a set of PRNU values by using a binary write command see Section 7 3 on page 175 to write a value to the Generate field of the Shading Value Generate CSR see page 157 8 The camera must make at least 128 acquisitions to generate a set of PRNU values If your camera is set to control exposure with an ExSync signal you must generate at least 128 ExSync signal cycles after you signal the camera to begin generating the values If you are running the camera in a free run exposure time control mode you must wait long enough for the camera to complete at least 128 acquisitions a When the camera is capturing the lines it needs to create the PRNU shading values the line valid and data valid signals will go high and low as you would normally expect Basler sprint 105 Features However the data in these lines is not useful to you
15. Offset CSR Note The offset can be set by writing a floating point value to the Absolute Offset field or by writing an integer value to the Raw Offset field See Section 7 2 2 1 on page 143 for an explanation of the difference between these two fields Register Base Address 0x0F00 Field Name Register Status Offset 0x0000 Size 1 Byte Type Read only Description The integer value in this field indicates the status of this inquiry register 0x00 The register is not available 0x01 The register is available and all related settings are OK 0x80 A value in the register is set out of range Field Name Absolute Offset Offset 0x0001 Size 4 Bytes Type Read Write Description Writing a floating point value to this field directly sets the offset in DN digital numbers For example if you set this value to 5 00 you would increase the digital values output from the camera by 5 The allowed range for the absolute offset can vary depending on how the camera is configured You should check the absolute min and absolute max fields of this register to determine the allowed range with the current configuration The increment is 0 01 The value in this field is a standard IEEE 754 single precision 32 bit floating point number See Section 6 1 on page 95 for more information about offset Field Name Absolute Min Offset 0x0005 Size 4 Bytes Type Read only Description Minimum allowed floating point value for the absolute offse
