I’m using a 180 degree FOV fisheye camera for a project and am having difficulty getting OpenCV to display the entire camera frame. When I open the camera in the standard Windows camera app it shows the full 180 degree FOV, but when I use a simple script to display the camera in Python it crops a decent chunk of the image and nearly halves the FOV.

Image using Windows camera app: [Windows — ImgBB](https://ibb.co/WFK8Jm2)

Image when Python script is running: [python — ImgBB](https://ibb.co/QddnWXJ)

Below is the code I’m using:

```
import cv2

cap = cv2.VideoCapture(0)

if not cap.isOpened():
    raise IOError("Cannot open webcam")

while True:
    ret, frame = cap.read()
    frame = cv2.resize(frame, (1500,1000), fx=0, fy=0, interpolation=cv2.INTER_AREA)
    cv2.imshow('Input', frame)

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

cap.release()
cv2.destroyAllWindows()

```

Anyone know how to stop this auto-cropping and display the full frame? Resizing the window doesn’t help. Any help would be much appreciated!
