Issue

In the line imgtk = ImageTk.PhotoImage(image=cv2image), you are passing a numpy array (cv2image) as input to ImageTk.PhotoImage. But the source code of PIL.ImageTk mentions that it requires a PIL image.

This is what source code of PIL.ImageTk mentions for init() of PhotoImage.

class PhotoImage(object):
    .....
    :param image: Either a PIL image, or a mode string.  If a mode string is
              used, a size must also be given.

Solution

So basically, you will have to convert the numpy array to a PIL Image and then pass it to ImageTk.PhotoImage().

So, can you replace the line imgtk = ImageTk.PhotoImage(image=cv2image) with imgtk = ImageTk.PhotoImage(image=PIL.Image.fromarray(cv2image))?

This would convert the numpy array to a PIL Image and it would be passed into the method.

I extracted the code for converting a numpy array to PIL Image from this source.
