IBIS4-1300
1.3 MPxl Rolling Shutter CMOS Image
Sensor
Overview
The IBIS4-1300 is a digital CMOS active pixel image sensor
with SXGA format.
Due to a patented pixel configuration a 60% fill factor and 50%
quantum efficiency are obtained. This is combined with an
on-chip double sampling technique to cancel fixed pattern
noise.
Features
• SXGA resolution: 1280 x 1024 pixels
• High sensitivity 20 µV/e-
• High fill factor 60%
• Quantum efficiency > 50% between 500 and 700 nm.
• 20 noise electrons = 50 noise photons
• Dynamic range: 69 dB (2750:1) in single slope operation
• Extended dynamic range mode (80…100 dB) in double
slope integration
• On-chip 10 bit, 10 mega Samples/s ADC
• Programmable gain & offset output amplifier
• 4:1 sub sampling viewfinder mode (320x256 pixels)
• Electronic shutter
• 7 x 7 µm2 pixels
• Low fixed pattern noise (1% Vsat p/p)
• Low dark current: 344 pA/cm2
• (1055 electrons/s, 1 minute auto saturation)
• RGB or monochrome
• Digital (ADC) gamma correction
