Column FPN Correction

The column FPN of the sensor is improved by the offset

correction of the columns. At the start of every frame, before read

out of the actual lines is done, a fixed voltage is applied at the

columns and these values are read out like a real data line. Inside

the data block, the 'pixel' data for that line is stored in an on-chip

FPN memory. When the correction is enabled, the corresponding

FPN value is subtracted from the incoming pixel data.

This FPN correction must be enabled for every output separately.

The registers used to configure the correction are:

■ datachannelX_1 with X from 0 to 11. The field [1] of these

registers enables the offset corrections of the specific output

channel.

Note Do not change the settings of datachannel12_1. This

channel contains synchronization data, not pixel data. If fpn

correction is enabled on this channel, the synchronization data

becomes corrupt.

■ seqmode3. The field[2] must be '1'. It enables the generation

of the line of reference voltages at the columns.

Figure 23 and Figure 24 show the effect of enabling the column

FPN correction. These images are magnified up to five times.
