 ## Overview
 
-This example demonstrates how to use the esp_driver_cam component to capture camera sensor signals and display it via DSI interface.
+This example demonstrates how to use the esp_driver_cam component to capture camera sensor signals and display it via DSI interface. This example will auto-detect camera sensors via [ESP camera sensor driver](https://components.espressif.com/components/espressif/esp_cam_sensor/versions/0.5.3) and capture camera sensor signals via CSI interface and display it via DSI interface.
 
 ## Usage

 ### Hardware Required
 
-This example requires:
-
-- OV5647 camera sensor
-- ILI9881C LCD screen
+- OV5647 or SC2336 camera sensor, or other camera sensors
+- EK79007 or ILI9881C LCD screen
 - ESP32P4 devkit
 
+**Note:** OV5647 has its own ISP functions, whereas SC2336 is a camera sensor without ISP functions. You can use the ESP on-chip ISP functions to tune the image together with the sensor ISP functions, if the image quality is not as expected.
+
+**Note:** For EK79007 you will need to connect following pins:
+- 5V - 5V
+- GND - GND
+- RST_LCD - 3V3
+
+You can also connect camera sensors and LCD screens from other vendors to the ESP chip, you can find corresponding camera or LCD drivers from [ESP Component Registry](https://components.espressif.com), or design your own customized drivers.

 ## Overview
 
-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.
+This example demonstrates how to use the ISP (image signal processor) to work with esp_driver_cam component. This example will auto-detect camera sensors via [ESP camera sensor driver](https://components.espressif.com/components/espressif/esp_cam_sensor/versions/0.5.3) and 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.
 
 ## Usage
 
 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.
-- ILI9881C LCD screen
+- OV5647 or SC2336 camera sensor, or other camera sensors
+- EK79007 or ILI9881C LCD screen
 - ESP32P4 devkit
 
+**Note:** OV5647 has its own ISP functions, whereas SC2336 is a camera sensor without ISP functions. You can use the ESP on-chip ISP functions to tune the image together with the sensor ISP functions, if the image quality is not as expected.
+
+**Note:** For EK79007 you will need to connect following pins:
+- 5V - 5V
+- GND - GND
+- RST_LCD - 3V3
+
+You can also connect camera sensors and LCD screens from other vendors to the ESP chip, you can find corresponding camera or LCD drivers from [ESP Component Registry](https://components.espressif.com), or design your own customized drivers.
