timelapsed camera (Read 1176 times)

moggis YaBB Newbies Offline Posts: 8 denmark	timelapsed camera Jul 12^th, 2005, 1:24pm im a newbie to processing and i was wondering how you could make a timelapsed camera thing-a-mading - you know one that captures 2 frames every 15 minutes or so. filming things that grow for instance?

flight404 Full Member Offline Posts: 139	Re: timelapsed camera Reply #1 - Jul 12^th, 2005, 9:28pm It would be fairly straightforward. Have a timer in your processing sketch that triggers a saveFrame every 7.5 minutes (or whatever duration you want). After you have all the frames, you can easily piece them together using something like Quicktime Pro.

moggis YaBB Newbies Offline Posts: 8 denmark	Re: timelapsed camera Reply #2 - Jul 13^th, 2005, 3:07am straight forward you say! could you perhaps give me an example of how the code would look like (like I said im totally new to this)

try this. havent tested with camera (left it at the office).

Code:


import processing.video.*;
Camera camera;

// how many seconds between each saveFrame
int timeDelay;

// total number of saved images
int imageCounter;

void setup(){
  size(800,600,P2D);
  
  // set the program to run at a framerate of once per second
  framerate(1);
  
  // new camera object, 800x600 resolution
  camera = new Camera(this, 800, 600);
  
  // 10 second delay between each saveFrame
  timeDelay = 10;
}


void draw(){
  if (second()%timeDelay == 0){
    background(0);
    camera.read();
    image(camera, 0, 0);
    saveFrame("screenGrabs/frames####.tif");

    println("saving image " + imageCounter + " :: " + (imageCounter * timeDelay) + " seconds");
    imageCounter ++;
  }
}

flight404 Full Member Offline Posts: 139	Re: timelapsed camera Reply #7 - Jul 13^th, 2005, 5:54pm oh, by the way, 'camera' should be 'capture', and 'Camera' should be 'Capture'. I get those mixed up sometimes.

moggis YaBB Newbies Offline Posts: 8 denmark	Re: timelapsed camera Reply #8 - Jul 13^th, 2005, 5:56pm yeah I figured it out! now to filming things that grow! i guess it should take about a week or so;-)

ive created a slightly modified version of the code here for a project, but im stuck. what ive got:

Code:


import processing.video.*; 
Capture camera; 
 
// how many seconds between each saveFrame 
int timeDelay; 
// total number of saved images 
int imageCounter; 
 
void setup(){ 
 
  size(320,240); 
   
 
  framerate(12); 
   
  
  camera = new Capture(this, 320, 240, 12); 
   
  // set timeDelay to zero initially
  timeDelay = 0; 
} 
 
 
void draw(){ 
    camera.read(); 
    image(camera, 0, 0); 
    //println (timeDelay);
    timeDelay = (timeDelay + 1);   //just incrementing timeDelay because its 
	if (timeDelay == 75){		 //the simplest timer i could come up with.
	    background(0); 
	    camera.read(); 
	    image(camera, 0, 0); 
	    saveFrame("screenGrabs/frames####.tif"); 
	    println("saving image " + imageCounter + " :: " + (imageCounter * timeDelay) + " seconds"); 
	    imageCounter ++; 
	    timeDelay = 0;  //resetting timeDelay to 0 for the next picture time.
	} 
}

so this is just a modified version of what flight404 had posted. what i am stuck on is getting it to load the pictures its saving as background images for the movie. so what would happen if this were all working as intended is that it would be capturing an image ~7 seconds and saving it to disc. all the while a live stream is playing, adding a layer mask or alpha mask to create interesting blending effects between the video and still image. i dont think i explained that very well. any help would be appreciated.
