TDA4AEN-Q1: NSF4 noise threshold interpolation

Part Number: TDA4AEN-Q1

Tool/software:

Deat TI experts,

We'd like to know if there exists interpolation calculation between noise threshold from different region.

If we set gain trigger region as below, then how to get the noise threshold during gain=24 to 32?

 <region0 class="0">
<colortemperature val="2" min="0" max="20000"> </colortemperature>
<exposure val="1" min="0" max="10000000"> </exposure>
<gain val="0" min="0" max="24"> </gain>
</region0>

<region1 class="1">
<colortemperature val="2" min="0" max="20000"> </colortemperature>
<exposure val="1" min="0" max="10000000"> </exposure>
<gain val="0" min="32" max="1024"> </gain>
</region1>

  • Hi Taylar,

    In current SDK, we don't interpolate the noise thresholds.
    You can find the source code under "imaging/algo/dcc/" and under the VISS kernel implementation.

    If we set gain trigger region as below, then how to get the noise threshold during gain=24 to 32?

    That is not allowed.
    You should not leave a gap from 24 to 32.
