Weird image capture

[Goczilla]

Hello,

I am discovering this library which seems to be very helpful to acquire data from a Lepton camera. However, when I try to acquire an image, first the time to execute the capture function of Lepton.py file is very random (between 0.01 and 30s), and second the image display is weird. I can see my "shape" but with a lot of noise or like if pixels are dead. But, using an old software of my colleague (using C++/Python and Perl), the camera is ok and works correctly. So it deals with my code but I can see where.

Can you help me please ? I thank you in advance.

import sys
import numpy as np
from pylepton import Lepton
import matplotlib.pyplot as plt

with Lepton() as l:
    image = np.zeros((60, 80, 1), 'float')  # to perform operation after

    # Capture image
    _, new_sum = l.capture(image)

    # Normalize between 0 and 1
    data = np.reshape(np.rot90(image,1),60*80,1)
    data2=data-min(data)
    data2=data2/max(data2)
    data2=np.reshape(data2, (60,80))
    data = 255.*data2
    data = np.squeeze(image)

# Plotting image acquired
fig = plt.figure()
im = plt.imshow(data)
pos = fig.add_axes([0.93,0.05,0.05,0.8])
fig.colorbar(im, cax=pos) 
plt.show()

It would be best to post this question on the Lepton Google group along with an image of the artifact you're seeing (this will really help), and I'll be happy to review your code.
