Now faster with the linear probe! Optimized code would look like:

import streamlit as st
import pyusbus as usbProbe
import cv2

image_zone = st.empty()

probe = usbProbe.UP20()

while True:     
    img = probe.getImage()   
    rgb = cv2.cvtColor(img, cv2.COLOR_GRAY2BGR) 
    res = cv2.resize(rgb, dsize=(440, 500), interpolation=cv2.INTER_CUBIC)    
    image_zone.image(res)
