Flir Lepton constantly showing the same temperatures !

Where do I go wrong, temperatures change very little ?

import cv2

from flirpy.camera.lepton import Lepton import numpy as np

cv2.namedWindow("output", cv2.WINDOW_NORMAL) font = cv2.FONT_HERSHEY_SIMPLEX fontScale = 0.4 fontColor = (255,255,255) lineType = 1

with Lepton() as camera:

 scale_percent = 4 # percent of original size
 while True: 
    img = camera.grab().astype(np.float32)
    # Rescale to 8 bit
    img = 255*(img - img.min())/(img.max()-img.min())
    img=img.astype(np.uint8)
    #img=plt.imshow(img, cmap=cm.plasma)
    img= cv2.applyColorMap(img, cv2.COLORMAP_JET)
    ffc_temp_c=camera.ffc_temp_k# -273.15
    ffc_temp_c=round(ffc_temp_c,2)
    fpa_temp_c=camera.fpa_temp_k#-273.15
    fpa_temp_c=round(fpa_temp_c,2)   

    cv2.putText(img,"temp_k:"+str(ffc_temp_c),  (5,10) ,  font, fontScale, fontColor, lineType)
    cv2.putText(img,"temp_c:"+str(fpa_temp_c), (5,20),  font, fontScale, fontColor, lineType)

    cv2.imshow('output', img)
    if cv2.waitKey(1) == 27:
        break  # esc to quit

camera.close()
cv2.destroyAllWindows()

The code you posted does not use pylepton, so I'm closing this issue.
