Chapter 14 Camera Web Server
Open the video streams server function of the camera and print its IP address via serial port.
startCameraServer();
Serial.print("Camera Ready! Use 'http://");
Serial.print(WiFi.localIP());
Serial.println("' to connect");
Configure the display image information of the camera.
The set_vflip() function sets whether the image is flipped 180°, with 0 for no flip and 1 for flip 180°.
The set_brightness() function sets the brightness of the image, with values ranging from -2 to 2.
The set_saturation() function sets the color saturation of the image, with values ranging from -2 to 2.
sensor_t * s = esp_camera_sensor_get();
// initial sensors are flipped vertically and colors are a bit saturated
if (s->id.PID == OV3660_PID) {
s->set_vflip(s, 1); // flip it back
s->set_brightness(s, 1); // up the brightness just a bit
s->set_saturation(s, -2); // lower the saturation
}
Modify the resolution and sharpness of the images captured by the camera. The sharpness ranges from 10 to
63, and the smaller the number, the sharper the picture. The larger the number, the blurrier the picture. Please
refer to the table below.
config.frame_size = FRAMESIZE_UXGA;
config.jpeg_quality = 10;
config.fb_count = 2;
