2022-06-29ipa: raspberrypi: Add sensor temperature to DeviceStatusNaushir Patuck
Add an optional sensor_temperature field to the DeviceStatus structure. If a temperature measurement is available for a frame, the value is returned out through the SensorTemperature control in the Request metadata. Additionally, provide the sensor temperature value from the std::ostream &operator<< overload.

2022-04-06ipa: raspberrypi: alsc: Limit the calculated lambda valuesNaushir Patuck
Under the right circumstances, the alsc calculations could spread the colour errors across the entire image as lambda remains unbound. This would cause the corrected image chroma values to slowly drift to incorrect values. This change adds a config parameter (alsc.lambda_bound) that provides an upper and lower bound to the lambda value at every stage of the calculation. With this change, we now adjust the lambda values so that the average across the entire grid is 1 instead of normalising to the minimum value.

2022-02-08ipa: raspberrypi: awb: Better handling of how we disable AWBDavid Plowman
We now handle disabling ("pausing") AWB in the same way as AEC/AGC. Instead of letting the pause flag be set so that the code never runs at all, we instead fix the manual settings to the current values (but continue to be called). The algorithm does not restart any calculations in this state, but continues to add AWB metadata to every frame. Therefore certain other algorithms that want to know it (CCM and ALSC, for example) can still find it.

Process() does not restart the asynchronous thread when manual gains are in force. 3.
