This example demonstrates how to use the ISP (image signal processor) to work with esp_driver_cam component. This example will capture camera sensor signals via CSI interface and display it via DSI interface. This example also enables the ISP AF (auto-focus) feature and ISP BF (bayer denoise) feature.
The subsections below give only absolutely necessary information. For full steps to configure ESP-IDF and use it to build and run projects, see [ESP-IDF Getting Started](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html#get-started).
### Hardware Required
This example requires:
- OV5647 camera sensor with VCM (Voice Coil Motor). The VCM used in this example is DW9714.
First of all, your target must be supported by both:
- **By your ESP-IDF version**: For the full list of supported targets, run:
```
idf.py --list-targets
```
- **By this example**: For the full list of supported targets, refer to the supported targets table at the top of this README.
After you make sure that your target is supported, go to your example project directory and [set the chip target](https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/tools/idf-py.html#select-the-target-chip-set-target):
```
idf.py set-target <target>
```
For example, to set esp32-P4 as the chip target, run:
```
idf.py set-target esp32p4
```
### Configure the Project
For information about Kconfig options, see [Project Configuration](https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/kconfig.html) > _Name of relevant section(s)_.
To conveniently check or modify Kconfig options for this example in a project configuration menu, run:
```
idf.py menuconfig
```
```
Set CONFIG_CAMERA_OV5647 to y
```
### Build and Flash
Execute the following command to build the project, flash it to your development board, and run the monitor tool to view the serial output:
```
idf.py build flash monitor
```
This command can be reduced to `idf.py flash monitor`.
If the above command fails, check the log on the serial monitor which usually provides information on the possible cause of the issue.
To exit the serial monitor, use `Ctrl` + `]`.
## Example Output
If you see the following console output, your example should be running correctly:
```
I (1085) main_task: Calling app_main()
I (1095) ili9881c: ID1: 0x98, ID2: 0x81, ID3: 0x5c
I (1295) ov5647: Detected Camera sensor PID=0x5647 with index 0
I (1305) cam_dsi: fmt[0].name:MIPI_2lane_24Minput_RAW8_800x1280_50fps
I (1305) cam_dsi: fmt[1].name:MIPI_2lane_24Minput_RAW8_800x640_50fps
I (1315) cam_dsi: fmt[2].name:MIPI_2lane_24Minput_RAW8_800x800_50fps
I (1355) cam_dsi: Format in use:MIPI_2lane_24Minput_RAW8_800x640_50fps
```
You will also see the screen auto-focus when the screen image changes.
