OVERVIEW
The CMV12000 is a high speed CMOS image sensor with 4096 by 3072 pixels (22.5mm x 16.9mm) developed for machine vision and other applications. The image array consists of 5.5μm x 5.5μm pipelined global shutter pixels which allow exposure during read-out. The image sensor has 64 8-, 10- or 12-bit digital LVDS outputs (serial). The image sensor also integrates a programmable gain amplifier and offset regulation. Each channel runs at 600 Mbps which results in 132 fps frame rate at full resolution and 12-bit. When 10-bit per pixel is used, the frame rate increases to 300 fps. Higher frame rates can be achieved in row-windowing mode or row-subsampling mode. These modes are all programmable using the SPI interface. All internal exposure and read-out timings are generated by a programmable on-board sequencer. External triggering and exposure programming is also possible. Extended optical dynamic range can be achieved by multiple integrated high dynamic range modes.
