If limited color range mode is selected, the color range of RGB is 16~240, and the color range of YUV is Y[16~240], UV[16~235].
Full color range mode has a wider color range, so details in the image show more clearly.
Please confirm the color range mode of the current camera sensor, incorrect color range mode may cause color difference in the final converted image.
Full range mode is used by default. If this option is not selected, the format conversion function will be done using the limited range mode.

# ESP32 Camera Driver
[![Build examples](https://github.com/espressif/esp32-camera/actions/workflows/build.yml/badge.svg)](https://github.com/espressif/esp32-camera/actions/workflows/build.yml)
## General Information
This repository hosts ESP32 series Soc compatible driver for image sensors. Additionally it provides a few tools, which allow converting the captured frame data to the more common BMP and JPEG formats.
### Supported Soc
- ESP32
- ESP32-S2
- ESP32-S3
### Supported Sensor

## Important to Remember
- Except when using CIF or lower resolution with JPEG, the driver requires PSRAM to be installed and activated.
- Using YUV or RGB puts a lot of strain on the chip because writing to PSRAM is not particularly fast. The result is that image data might be missing. This is particularly true if WiFi is enabled. If you need RGB data, it is recommended that JPEG is captured and then turned into RGB using `fmt2rgb888` or `fmt2bmp`/`frame2bmp`.
- When 1 frame buffer is used, the driver will wait for the current frame to finish (VSYNC) and start I2S DMA. After the frame is acquired, I2S will be stopped and the frame buffer returned to the application. This approach gives more control over the system, but results in longer time to get the frame.
- When 2 or more frame bufers are used, I2S is running in continuous mode and each frame is pushed to a queue that the application can access. This approach puts more strain on the CPU/Memory, but allows for double the frame rate. Please use only with JPEG.
## Installation Instructions
### Using esp-idf
- Clone or download and extract the repository to the components folder of your ESP-IDF project
- Enable PSRAM in `menuconfig` (also set Flash and PSRAM frequiencies to 80MHz)
- Include `esp_camera.h` in your code
### Using PlatformIO
The easy way -- on the `env` section of `platformio.ini`, add the following:
```ini
[env]
lib_deps =
esp32-camera
```
Now the `esp_camera.h` is available to be included:
```c
#include "esp_camera.h"
```
Enable PSRAM on `menuconfig` or type it direclty on `sdkconfig`. Check the [official doc](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/kconfig.html#config-esp32-spiram-support) for more info.
```
CONFIG_ESP32_SPIRAM_SUPPORT=y
```
***Arduino*** The easy-way (content above) only seems to work if you're using `framework=arduino` which seems to take a bunch of the guesswork out (thanks Arduino!) but also suck up a lot more memory and flash, almost crippling the performance. If you plan to use the `framework=espidf` then read the sections below carefully!!
## Platform.io lib/submodule (for framework=espidf)
It's probably easier to just skip the platform.io library registry version and link the git repo as a submodule. (i.e. using code outside the platform.io library management). In this example we will install this as a submodule inside the platform.io $project/lib folder:
```
cd $project\lib
git submodule add -b master https://github.com/espressif/esp32-camera.git
```
Then in `platformio.ini` file
```
build_flags =
-I../lib/esp32-camera
```
After that `#include "esp_camera.h"` statement will be available. Now the module is included, and you're hopefully back to the same place as the easy-Arduino way.
**Warning about platform.io/espidf and fresh (not initialized) git repos**
There is a sharp-edge on you'll discover in the platform.io build process (in espidf v3.3 & 4.0.1) where a project which has only had `git init` but nothing committed will crash platform.io build process with highly non-useful output. The cause is due to lack of a version (making you think you did something wrong, when you didn't at all) - the output is horribly non-descript. Solution: the devs want you to create a file called version.txt with a number in it, or simply commit any file to the projects git repo and use git. This happens because platform.io build process tries to be too clever and determine the build version number from the git repo - it's a sharp edge you'll only encounter if you're experimenting on a new project with no commits .. like wtf is my camera not working let's try a 'clean project'?! </rant>
## Platform.io Kconfig
Kconfig is used by the platform.io menuconfig (accessed by running: `pio run -t menuconfig`) to interactively manage the various #ifdef statements throughout the espidf and supporting libraries (i.e. this repo: esp32-camera and arduino-esp32.git). The menuconfig process generates the `sdkconfig` file which is ultimately used behind the scenes by espidf compile+build process.
**Make sure to append or symlink** [this `Kconfig`](./Kconfig) content into the `Kconfig` of your project.
You symlink (or copy) the included Kconfig into your platform.io projects src directory. The file should be named `Kconfig.projbuild` in your projects src\ directory or you could also add the library path to a CMakefile.txt and hope the `Kconfig` (or `Kconfig.projbuild`) gets discovered by the menuconfig process, though this unpredictable for me.
The unpredictable wonky behavior in platform.io build process around Kconfig naming (Kconfig vs. Kconfig.projbuild) occurs between espidf versions 3.3 and 4.0 - but if you don't see "Camera configuration" in your `pio run -t menuconfig` then there is no point trying to test camera code (it may compile, but it probably won't work!) and it seems the platform.io devs (when they built their wrapper around the espidf menuconfig) didn't implement it properly. You've probably already figured out you can't use the espidf build tools since the files are in totally different locations and also different versions with sometimes different syntax. This is one of those times you might consider changing the `platformio.ini` from `platform=espressif32` to `platform=https://github.com/platformio/platform-espressif32.git#develop` to get a more recent version of the espidf 4.0 tools.
However with a bit of patience and experimenting you'll figure the Kconfig out. Once Kconfig (or Kconfig.projbuild) is working then you will be able to choose the configurations according to your setup or the camera libraries will be compiled. Although you might also need to delete your .pio/build directory before the options appear .. again, the `pio run -t menuconfig` doens't always notice the new Kconfig files!
If you miss-skip-ignore this critical step the camera module will compile but camera logic inside the library will be 'empty' because the Kconfig sets the proper #ifdef statements during the build process to initialize the selected cameras. It's very not optional!
