Vita 1300 sensor
Cypress Semiconductor has introduced a high-sensitivity, high-speed CMOS image sensor targeted at the machine vision market. The 1.3 Megapixel Vita 1300 sensor combines a pipelined and triggered global snapshot shutter with a high frame rate of 150fps for undistorted images and fast readout. The pipelined snapshot shutter capability enables exposure during read-out to reduce motion blur. The sensor also works in a rolling shutter mode with Correlated Double Sampling (CDS) to reduce noise and increase dynamic range. The Vita 1300 family builds on the success of Cypress's IBIS5 imagers in the machine vision market, and also addresses barcode scanning, motion monitoring and security applications.
The Vita 1300 sensor offers a 1/2-inch optical format with monochrome or colour digital output. The sensor has four 10-bit digital Low Voltage Differential Signalling (LVDS) outputs that enable transfer of image data over a standard industry protocol at low power and low noise. It also has a multiple slope capability to maintain good contrast in shadowed regions without saturating bright areas in scenes with a high contrast ratio.
The sensor has 1,280 x 1,024 active pixels with 4.8 x 4.8µm pixel size. It integrates a programmable offset and gain amplifier for each channel of the LVDS outputs. Each channel runs at 620Mbps, which results in 150fps frame rate at full resolution. Higher frame rates can be achieved by windowing or sub-sampled readout modes.
