Left/Right Gain Balance CSR
Note: The left/right gain balance can be set by writing a floating point value to the Absolute L/R
Gain Balance field or by writing an integer value to the Raw L/R Gain Balance field. Refer to
Section
4.2.2.1 for an explanation of the difference between these two fields.
Register Base Address: 0x0E20
Field Name: Register Status Offset: 0x0000 Size: 1 Byte Type: Read only
Description: The integer value in this field indicates the status of this control register:
0x00 = The register is not available
0x01 = The register is available. All related settings are OK
0x80 = A value in the register is set out of range
Field Name: Absolute L/R Gain Balance Offset: 0x0001 Size: 4 Bytes Type: Read / Write
Description: Writing a floating point value to this field to sets the left/right gain balance in dB. For exam-
ple, if the value in this field is set to +0.55, the left/right gain balance would be +0.55 dB.
The left/right gain balance can normally range from -1.00 dB to +1.00 dB in increments of
0.01.
The value in this field is a standard IEEE-754 single precision (32 bit) floating point number.
See Section 3.6.2 for more information about gain balance.
Field Name: Absolute Min Offset: 0x0005 Size: 4 Bytes Type: Read only
Description: Minimum allowed floating point value for the absolute left/right gain balance setting.
The value in this field is a standard IEEE-754 single precision (32 bit) floating point number.
Field Name: Absolute Max Offset: 0x0009 Size: 4 Bytes Type: Read only
Description: Maximum allowed floating point value for the absolute left/right gain balance setting.
The value in this field is a standard IEEE-754 single precision (32 bit) floating point number.
Field Name: Raw L/R Gain Balance Offset: 0x000D Size: 2 Bytes Type: Read / Write
Description: Writing an integer value to this field sets the left/right gain balance.
The value can normally range from 228 (0x00E4) to 288 (0x0120).
The dB of left/right gain balance that the camera will apply at a given setting in this field is
determined by this formula:
dB = 20 x log ( raw setting / 256 )
For example, if the value in this field is set to 270 (0x00F0), then:
dB = 20 x log (270 / 256)
dB = +0.46
The 2 bytes in this field are interpreted as follows:
Byte 1 = Low byte of the raw value
Byte 2 = High byte of the raw value
See Section 3.6.2 for more information about gain balance.
