- New 2A algorithms:
The Auto-Exposure (AE) algorithm is now based on lux estimation, providing a faster and more stable approach to achieve the luminance target.
The Auto White Balance (AWB) algorithm now uses color ratios to reach color accuracy more quickly and with greater stability. Additionally, this new algorithm offers improved rendering between two profiles through interpolation. - New tuning parameters are now required to run the new 2A algorithms. These parameters are avalaible for the following list of sensors:
IMX335
VD66GY
VD5943 (MONO)
VD1943
VD65G4
VD56G3 (MONO)
Known Issues and Limitations
- Not compatible with version 1.3.0 of STM32 ISP IQTune desktop application. A new compatible version 2.0.0 will be released beginning of 2026.
