2.2 CMOS SENSOR
2.2.1 Inca 311
In the Inca 311 a monochrome sensor PCS2112-LM from
Zoran is implemented. This high performance CMOS
imaging sensor has an extreme ‘uniform pixel array’ and
an extremely low ‘fixed-pattern noise’ because of its
‘Distributed Pixel Amplifier’ architecture. The following
main features, supported by the Inca 311, are available:
• 1280 x 1024 Pixels
• 10 bit ADC resolution
• 2/3” sensor housing
• One region of interest
• Programmable exposure time
• Mirror and flipped scan modes
• 16 MHz or 24 MHz pixelclock
• Full frame rate 9.3 or 14 frames per second
• Programmable gain 0..14 dB
• Dynamic range 66dB
• Synthetic test image
• Decimation factor 2 and 4 for higher frame rates of
sub- sampled images
2.3 CAMERA CONNECTIONS
The rear side of the camera gives the user a great number
of possibilities for interfacing the camera.
• IEEE 1394 (also known as Firewire™)
• One trigger input and one output for flash control
• Digital input 6 bits optically isolated
• Digital output 6 bits optically isolated
• RS232
• Camera reset
• Watchdog
• VGA and CVBS for display purposes
