Imaging systems are analogous in many respects
to classical thermodynamic systems with nodes
and pipes. Similar to how nodes store mass
and pipes transport the mass from node to node,
client and server computers store images,
and networks transport them. Moreover, just as
mass can change state, digital images can be
processed and modified. Digital image
formats are ways to represent images in
digital form. There are many different digital
image formats in use today, and this creates
an additional level of complexity for imaging
systems beyond the analogy with thermodynamic
systems. Some digital image formats are
more widely adopted than others, and it is
important when designing an imaging product to
consider formats used by complementary
products.

| Digital Camera Formats |
| Flashpix |
| I3A |
Flashpix provides resolution independent images containing scene and transformation metadata. Created by the I3A. |
| JPEG 2000 File Format for Digital Images |
| JPEG 2000 |
JPEG 2000 combines advanced wavelet compression, multiple resolutions and extensive metadata. JPEG 2000 was developed by the JPEG Committee, a non-profit working group of ISO. |
| EE Times |
EE Times has an interesting article article about JPEG2000 Internet imaging and hardware design work. |
| PNG Portable Network Graphics |
| PNG |
This website describes PNG (Portable Network Graphics), an extensible file format for the lossless, portable, well-compressed storage of raster images. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-color, grayscale, and truecolor images are supported, plus an optional alpha channel. |
