espressif/esp_ipa

changelog

## 1.3.0

- Add auto BLC(black level correction) algorithm

## 1.2.0

- Add ATC model 0 algorithm
- Package the libesp_ipa.a library that compiled based on esp-idf master(v6.0.0)

## 1.1.0

- Modify the exposure adjustment algorithm of the part-anti-flicker mode
    - If the target gain exceeds the maximum or minimum value, the AGC ignores the anti-flicker and uses all exposure time

## 1.0.1

- Fix the light flicker issue in the part-anti-flicker mode

## 1.0.0

- Add extended configuration to set hue, brightness and statistics window
- Add an autofocus control algorithm to set the sensor focus position by controlling the sensor motor

## 0.3.0~1

- Fix the compiling error with esp-idf v5.4-

## 0.3.0

- Add ATC to configure sensor AE target level by JSON configuration
- AGC different directions of gain and exposure adjustment support different speed parameters
- AGC supports the all exposure range in the part anti-flicker mode
- ACC supports LSC JSON configuration
- ACC adds CCM model 1 to calculate CCM by interpolation algorithm
- ADN JSON configuration supports to generate Gaussian matrix by sigma parameter
- AWB supports to configure statistics parameters
- Pipeline global variables support buffer pointer
- Pipeline supports to add customized IPA node
