Cypress Semiconductor has launched high-speed, highly-sensitive CMOS image sensors to be used for high-end machine vision systems. This 25-megapixel based VITA 25K provides maximum throughput in the market for a gadget having a triggered and a pipelined global shutter.
The sensor provides thirty two, ten-bit based Low Voltage Differential Signaling (LVDS) type of outputs to facilitate image data transfer at low noise and low power on standard industry protocol. Every channel operates at 620 Mbps, resulting in a large 53 frames per second frame rate for fast readout and undistorted images at full resolution. The VITA 25K is useful in high-end machine vision applications like intelligent traffic systems, inspection machines, and biometric inspection like new-generation palm print readers.
The pipelined global shutter functionality also facilitates exposure while reading-out for decreasing motion blur. The sensor can function in a rolling shutter mode along with correlated double sampling (CDS) for increasing dynamic range and reducing noise.
Customers will be able to program a maximum of 32 separate regions of interest to for in-depth observation from the sensor’s image. The VITA 25K sensors have been built on the 1.3-megapixel VITA 1300 portfolio’s capabilities. These sensors are undergoing wide ranging sampling tests and likely to be manufactured in 2010.
Cypress will showcase its standard CMOS image sensor and industry-leading custom solutions, including VITA portfolio offerings at its booth during June 9-11, 2010 at the Yokohama, Japan-based 2010 Image Sensing Show.
The sensor has integrated a programmable gain and offset amplifier for all the 32 LVDS output channels. Customers will get increased sensor frame rates with sub-sampled or windowed readout modes. They can program the settings of the sensor on an SPI interface. An on-board sequencer creates all timing and internal exposure of read-outs. The sensor permits multiple slopes to be set for increasing the dynamic range, and also maintains high contrast in an image’s shadowed regions without saturating the scenes’ bright areas.
