Hello,
The patch series is to enhance image quality for IPU3 devices with Intel
close IPA by improving AE/AF controls for clearer image, and minor
tuning changes for better saturation.
- Improve the AE performance and resolve AE hunting problem during converging
by matching the effective sensor controls with the corresponding statstistics.
- Enable auto focus and set lens controls to pipeline handler.
- Use tuned parameters for gbce and tone mapping.
Han-Lin Chen (6):
ipu3: Use ia_aiq_frame_use_preview as default mode for AIQ
ipu3: Add a class AiqResultsRingBuffer to reserve AiqResults history
ipu3: Set statistics with the effective AE AiqResults
ipu3: Apply auto focus and send lens controls to pipeline handler
ipu3: Run AIQ for the first frame to avoid blanking
ipu3: Use gbce and tone mapping from the tuning files
