Description

The IBIS5-B-1300 is a solid state CMOS image sensor that integrates the functionality of complete analog image acquisition, digitizer and digital signal processing system on a single chip. This 1.3-mega pixel (1280 x 1024) CMOS active pixel sensor dedicated to industrial vision applications features both rolling and snapshot (or global) shutter. Full frame readout time is 36 ms (max. 27.5 fps), and readout speed can be boosted by windowed region of interest (ROI) readout. High dynamic range scenes can be captured using the double and multiples slope functionality. The sensor is available in a Monochrome version or Bayer (RGB) patterned color filter array.

User programmable row and column start/stop positions allow windowing down to 2×1 pixel window for digital zoom. Sub sampling or viewfinder mode reduces resolution while maintaining the constant field of view and an increased frame rate. The analog video output of the pixel array is processed by an on-chip analog signal pipeline. Double Sampling (DS) eliminates the fixed pattern noise. The programmable gain and offset amplifier maps the signal swing to the ADC input range. A 10-bit ADC converts the analog data to a 10-bit digital word stream. The sensor uses an 2-wire, I2C-compatible, interface, a 3-wire Serial-Parallel (SPI) interface or a 16-bit parallel interface. It operates with a 3.3V power supply and requires only one master clock for operation up to 40 MHz. It is housed in an 84-pin ceramic LCC package.
