ABSTRACT
Digital cameras use solid-state devices as image sensors, formed by large arrays of photosensitive diodes. During the short period of time in which the shutter is open, each diode records the intensity of the light that falls on it by accumulating a charge. This brightness measurement is then digitized and stored in memory, forming a picture. Imagine now that we had one particular digital camera with
some rather unusual characteristics:
• Besides measuring brightness, diodes can also compute/communicate. • No central storage, diodes store an encoding of the whole image. • Communication among diodes happens over a wireless channel.
