How to get OpenCV to display entire camera frame?

[Pedroski55]

I never used cv2 with a webcam. I only use cv2 for marking multiple-choice questions.

Got the code from here.

This seems to show the whole picture, no cropping:

def camON():
    import cv2

    cap = cv2.VideoCapture(0)

    # Check if the webcam is opened correctly
    if not cap.isOpened():
        raise IOError("Cannot open webcam")

    while True:
        ret, frame = cap.read()
        # smaller window
        frame = cv2.resize(frame, None, fx=0.5, fy=0.5, interpolation=cv2.INTER_AREA)
        # bigger window
        #frame = cv2.resize(frame, None, fx=1, fy=1, interpolation=cv2.INTER_AREA)
        cv2.imshow('Input', frame)

        c = cv2.waitKey(1)
        if c == 27:
            break

    cap.release()
    cv2.destroyAllWindows()
