I'm using a web cam of resolution 640x480 and I want to increase the resolution to 1024x768 so that the camera video can come up on the full screen. I'm sending you a sample code and please check and give me feedback.

Note: I'm using version 2.3 of OPENCV on Visual Sudio C++ (2010)

CODE:

#include <WINDOWS.H>
#include "cv.h"
#include "highgui.h"
#include <stdio.h>
#include <stdlib.h>
#include <iostream>
#include <iomanip>
CvFont font;
IplImage* frame = 0;
CvCapture* capture;

using namespace std;

int main()
{
    CvCapture* capture=cvCreateCameraCapture(0);
    cvNamedWindow("Cam Feed",CV_WINDOW_NORMAL);

    while(1)
    {
        //Getting the present frame
        frame=cvQueryFrame(capture);

        capture = cvCreateCameraCapture(0);

        cvSetCaptureProperty( capture, CV_CAP_PROP_FRAME_WIDTH, 1024 );

        cvSetCaptureProperty( capture, CV_CAP_PROP_FRAME_HEIGHT, 768 );

        cvSetCaptureProperty(capture, CV_CAP_PROP_FPS, 5);

        frame = cvQueryFrame(capture);
        printf("camera: %f x %f\n", cvGetCaptureProperty(capture, CV_CAP_PROP_FRAME_WIDTH),cvGetCaptureProperty(capture, CV_CAP_PROP_FRAME_HEIGHT));
        BattleMenu();

        cvResizeWindow("Cam Feed", 1024, 768);

        cvMoveWindow("Cam Feed", 400, 130);
        cvWaitKey(1);
        cvShowImage("Cam Feed",frame);
    }

    /* free memory */
    cvDestroyWindow( "Cam Feed" );
    cvReleaseCapture( &capture );

    return 0;
}
