Get Full HD UImage from UIImagePickerControllerSourceTypeCamera without clicking a button

Question

At constant frequency, I want to get UIImage for some functionality

if (!_updateTimer) { _updateTimer = [[NSTimer scheduledTimerWithTimeInterval:self.updateFrequency target:self selector:@selector(updateLocations:) userInfo:nil repeats:YES] retain]; } 

where self.updateFrequency = 1 / 20.0;

How can I get an image constantly every second without pressing the capture button?

I do not need the following code, since it will give the image size of iphone 320 * 480

 CGImageRef cgoriginal = UIGetScreenImage(); CGImageRef cgimg = CGImageCreateWithImageInRect(cgoriginal, rect); 

I need a complete image that everything is hung on the camera at every frequent interval.

thanks

Call the takePicture method when you want to capture the image. You will get the image in delegate methods.

 extern CGImageRef UIGetScreenImage(); CGImageRef cgoriginal = UIGetScreenImage(); CGImageRef cgimg = CGImageCreateWithImageInRect(cgoriginal, rect); UIImage *viewImage = [UIImage imageWithCGImage:cgimg]; CGImageRelease(cgoriginal); CGImageRelease(cgimg);
