Hi Sarah
If you look at the example Video(Capture) in Processing you get this:
Code:
/**
* Getting Started with Capture.
*
* Reading and displaying an image from an attached Capture device.
*/
import processing.video.*;
Capture cam;
void setup() {
size(640, 480);
// If no device is specified, will just use the default.
cam = new Capture(this, 320, 240);
// To use another device (i.e. if the default device causes an error),
// list all available capture devices to the console to find your camera.
//String[] devices = Capture.list();
//println(devices);
// Change devices[0] to the proper index for your camera.
//cam = new Capture(this, width, height, devices[0]);
// Opens the settings page for this capture device.
//camera.settings();
}
void draw() {
if (cam.available() == true) {
cam.read();
image(cam, 160, 100);
// The following does the same, and is faster when just drawing the image
// without any additional resizing, transformations, or tint.
//set(160, 100, cam);
}
}
Notice that only when "image(cam, 160, 100)" is called does Processing display anything on the screen. So one solution could be to just show every 10. or so frame:
Code:
/**
* Getting Started with Capture.
*
* Reading and displaying an image from an attached Capture device.
*/
import processing.video.*;
Capture cam;
void setup() {
size(640, 480);
// If no device is specified, will just use the default.
cam = new Capture(this, 320, 240);
// To use another device (i.e. if the default device causes an error),
// list all available capture devices to the console to find your camera.
//String[] devices = Capture.list();
//println(devices);
// Change devices[0] to the proper index for your camera.
//cam = new Capture(this, width, height, devices[0]);
// Opens the settings page for this capture device.
//camera.settings();
}
void draw() {
if (cam.available() == true && frameCount % 10 == 0 ) //here!
{
cam.read();
image(cam, 160, 100);
// The following does the same, and is faster when just drawing the image
// without any additional resizing, transformations, or tint.
//set(160, 100, cam);
}
}
Hope this helps
