Did you know Nokia mobile phones with the S60 platform can be programmed in Python? During my last holiday, I wrote a small program for time lapse photography with my mobile. Here is the result, showing tidal ebbs and flows in Saint-Vaast-la-Hogue and Cancale:
This is the Python program I wrote to take a picture every minute:
#!/usr/bin/python
__description__ = 'Tool to take pictures with a Nokia phone at regular intervals'
__author__ = 'Didier Stevens'
__version__ = '0.1.1'
__date__ = '2009/06/22'

import camera
import time
import os
timelapseFolder = 'e:\\timelapse\\'
sleepTime = 57
def TakeAndSavePicture():
global timelapseFolder
now = '%04d%02d%02d-%02d%02d%02d' % time.localtime()[0:6]
pic = camera.take_photo()
pic.save(os.path.join(timelapseFolder, now, '.jpeg'))
print 'Picture taken: %s' % now
def Main():
global timelapseFolder
global sleepTime
print 'Timelapse photography started'
if not os.path.isdir(timelapseFolder):
os.mkdir(timelapseFolder)
print 'Timelapse folder created: %s' % timelapseFolder
print 'Wait between pictures %d' % sleepTime
while True:
TakeAndSavePicture()
time.sleep(sleepTime)
if __name__ == '__main__':
Main()
And then I use Avisynth to combine the jpeg pictures in a movie like this (I join pictures 00001.jpg through 00197.jpeg, 5 per second and produce a 25 fps movie):
ImageSource("%05d.jpeg", 1, 197, 5).ChangeFPS(25)
