# Code in C (due to memory-management requirements):

Allocate a huge buffer (1000 * sizeof(image))
for i in [0..1000]:
  tell camera it can use memory at buffer + i * sizeof(image)

getImage():
  get address of buffer used by camera to store image
  copy buffer data to new store
  tell camera it can use buffer again
  return data

# Code in Python
while True:
  image = getImage()
  image = fixImage(image) # Do some work
  self.client.receiveData(image)
