CMOS industrial image sensor delivers 70 million pixels at 3 frames per second
Image data are transferred through eight analog outputs, each running at the full master clock rate of 30MHz. Higher frame rates can be achieved in windowing or sub-sampling modes. The new image sensor also integrates a programmable gain amplifier, offset regulation, as well as on-chip timing generation. During the design of the sensor special precautions have been taken to assure that the two pixels with shared readout behave very similarly in terms of offset and gain, to avoid checkerboard-like artifacts and the need for off-chip calibration. This is particularly important for the B/W version since the effect, if present, would be masked by the bayer RGB CFA pattern in the CHR70M. Due to the staggered layout of the pixel readout circuitry all pixels show similar MTF behavior and angular sensitivity.
The sensor offers moving-window functionality. The windowing and other settings are programmable via the built-in SPI interface. All internal exposure and read-out timing values can be generated by a programmable on-board sequencer. External triggering and exposure programming is also possible. The CMOSIS CHR70M works with 3.3V signaling levels. It is packaged in a 65-pin ceramic PGA. The sensor will be available as a B/W with and without micro lenses, as well as a bayer RGB color version with microlenses. All versions will be offered with glass cover with two-sided anti-reflective coating (ARC).
