2. Outline
CMOS Cameras
CCD Cameras
Line Cameras

3. Why Buffered Cameras?
On-board memory used to temporarily store captured images.
Key advantages -
Multi-camera applications
Short & repeatable external trigger delay
Arbitrary ROI’s (with Nx and Ny multiples of 4)

4. Rolling Shutter vs Global Shutter

5. Rolling Shutter vs Global Shutter
Rolling Shutter cameras may distort moving objects
Global Shutter cameras don’t have the problem

6. Rolling Shutter vs Global Shutter
Pixels are exposed roll by roll
Usually has higher pixel count
Good for stationary or slow-moving objects
May distort image for moving objects
All pixels are exposed simultaneously
Good for moving objects
No image distortion

7. Cameras with Built-in LED Drivers for Illumination
Camera and LED drivers share the same PCB
Ideal for camera applications requiring LED illumination
4 channels (e.g. R, G, B, and white)
No external power supply needed
1W available for LED illumination
Controlled through the same USB and the same GUI-based software
SDK includes both camera and LED driver functions
Saves money
Saves space
Saves time
Saves trouble

8. Window-less USB2.0 CMOS Cameras
Why Window-less?
Better IR, VIS and UV
Optics or other components can get closer to the sensor
No unwanted optical interference due to multiple reflection
Mission-critical applications

9. Key Selling Points of Industrial Cameras
Highly reliable and widely tested SDK
Excellent synchronization capability (i.e. short and highly-repeatable external trigger delay)
Support multi-camera applications
DirectShow, TWAIN and Linux compatibility
USB protocol for non-Windows systems
Easy for system integration (e.g. with GPIOs, trigger in/out, etc.)
