Embedded Computing Seminar (fall 2005) 2
Does an Open Digital Camera Exist?
• Digita?– Partially open, but has disappeared off the
map [Why?]
• gPhoto?– Just interfacing with cameras
Embedded Computing Seminar (fall 2005) 3
Why an open Camera?
• Research is stifled as a result of proprietary technologies
• New ideas are hard to explore and test– E.g. the Refocusable camera
• Research is Expensive
Embedded Computing Seminar (fall 2005) 5
What is an Open Camera?
• What Technologies?
• What Hardware?
• What Software?
Embedded Computing Seminar (fall 2005) 6
Technologies
• Sensors
• Image Processing and Recognition
• Communications
• Display
• General Computing
Embedded Computing Seminar (fall 2005) 7
Hardware
• Sensors– Imaging– Motion– Location– More?
• DSP(s)• Controller• CPU• Display(s)
• GPU?• Audio Processor• Memory• Communications
Interfaces– IP, 802.11,
Cellular?– Wired and Wireless
interfaces
• More?

Software
• Open OS• Image Processing and Recognition• Audio Processing and Playback• Image compression (+ raw)• Video Codec(s)• On Board Server• On Board Editor/Debugger• Open SDK• Hardware Programmer/Debugger
Embedded Computing Seminar (fall 2005) 9
How to make this happen?
• Research the hardware and software needed for the project
• Acquire/Develop the hardware needed
• Develop a hardware platform
• Develop an open software platform
• Develop novel applications over this platform.
• Add hardware elements as needed to the platform

Yeah- lets be realistic!
• OK- until you get your $1M grant, what can you do?
• Low Cost Open camera:

Low Cost Open Camera
3. Take small laptop (with built in wireless )

Low Cost Open Camera
• The Open Box Camera is useful because:– Test real world scenarios Today– Explore interesting applications and
technologies Today without waiting for the hardware dev environments to catch up
– Low Risk: Lets you prove to yourself that there are interesting problems to solve or explore without spending too much money on it in the process
