ESP32 Camera Component

:description: Instructions for setting up the ESP32 Cameras in ESPHome
:image: camera.png
The ``esp32_camera`` component allows you to use ESP32-based camera boards in ESPHome that
directly integrate into Home Assistant through the native API.
.. warning::
Some ESP32 Camera boards have insufficient cooling and will overheat over time,
ESPHome does only activate the camera when Home Assistant requests an image, but
the camera until can still heat up considerably for some boards.
If the camera is not recognized after a reboot and the unit feels warm, try waiting for
it to cool down and check again - if that still doesn't work try enabling the test pattern.
.. note::
The example configuration is valid for M5Stack ESP32 camera models.

Configuration variables:
------------------------
- **name** (**Required**, string): The name of the camera.
Connection Options:
- **data_pins** (**Required**, list of pins): The data lanes of the camera, this must be a list
of 8 gpio pins.
- **vsync_pin** (**Required**, pin): The pin the VSYNC line of the camera is connected to.
- **href_pin** (**Required**, pin): The pin the HREF line of the camera is connected to.
- **pixel_clock_pin** (**Required**, pin): The pin the pixel clock line of the camera is connected to.
- **external_clock** (**Required**): The configuration of the external clock to drive the camera.
- **pin** (**Required**, pin): The pin the external clock line is connected to.
- **frequency** (*Optional*, float): The frequency of the external clock, must be either 20MHz
or 10MHz. Defaults to ``20MHz``.
- **i2c_pins** (**Required**): The i2c control pins of the camera.
- **sda** (**Required**, pin): The SDA pin of the i2c interface.
- **scl** (**Required**, pin): The SCL pin of the i2c interface.
- **reset_pin** (*Optional*, pin): The ESP pin the reset pin of the camera is connected to.
If set, this will reset the camera before the ESP boots.
- **power_down_pin** (*Optional*, pin): The ESP pin to power down the camera.
If set, this will power down the camera while it is inactive.
- **test_pattern** (*Optional*, boolean): When enabled, the camera will show a test pattern
that can be used to debug connection issues.
Frame Settings:
- **max_framerate** (*Optional*, float): The maximum framerate the camera will generate images at.
Up to 60Hz is possible (with reduced frame sizes), but beware of overheating. Defaults to ``10 fps``.
- **idle_framerate** (*Optional*, float): The framerate to capture images at when no client
is requesting a full stream. Defaults to ``0.1 fps``.
- **resolution** (*Optional*, enum): The resolution the camera will capture images at. Higher
resolutions require more memory, if there's not enough memory you will see an error during startup.
- ``160x120`` (QQVGA)
- ``128x160`` (QQVGA2)
- ``176x144`` (QCIF)
- ``240x176`` (HQVGA)
- ``320x240`` (QVGA)
- ``400x296`` (CIF)
- ``640x480`` (VGA, default)
- ``800x600`` (SVGA)
- ``1024x768`` (XGA)
- ``1280x1024`` (SXGA)
- ``1600x1200`` (UXGA)
- **jpeg_quality** (*Optional*, int): The JPEG quality that the camera should encode images with.
From 10 to 63. Defaults to ``10``.
- **contrast** (*Optional*, int): The contrast to apply to the picture, from -2 to 2. Defaults to ``0``.
- **brightness** (*Optional*, int): The brightness to apply to the picture, from -2 to 2. Defaults to ``0``.
- **saturation** (*Optional*, int): The saturation to apply to the picture, from -2 to 2. Defaults to ``0``.
- **vertical_flip** (*Optional*, bool): Whether to flip the image vertically. Defaults to ``true``.
- **horizontal_mirror** (*Optional*, bool): Whether to mirror the image horizontally. Defaults to ``true``.
