High-Speed Industrial Image Sensor Can See Colours

Cypress Semiconductor has announced the introduction of a high-sensitivity, high-speed Super Extended Graphics Array (SXGA)-resolution colour image sensor.

The LUPA-1300-2 was developed for machine-vision and motion-analysis applications that need to distinguish between different colours. The 1.3 megapixel LUPA-1300-2 colour sensor features a frame rate of 500 frames per second and a windowing capability that delivers undistorted images and fast readout.

The LUPA-1300-2 features a fully-synchronous snapshot shutter, making it possible to read one image while the next is being acquired and to capture images of moving objects without distortion. The sensor has 12 10-bit Low-Voltage Differential Signalling (LVDS) outputs.

The windowing capability enables the user to read only regions of interest in the image, increasing the effective frame rate. The image sensor also has a multiple-slope capability to maintain good contrast in shadowed regions without saturating bright areas in scenes with high contrast ratios.

The device has 1280 x 1024 pixels, with a pixel size of 14µm x 14µm. The image sensor integrates a programmable offset and gain amplifier for each channel of the LVDS outputs.

All internal exposure and read-out timings are generated by an on-board sequencer.

The intra-scene dynamic range can be increased by using the flexible multiple slope operating mode. The LUPA-1300-2 also features a 10-bit on-chip ADC to provide a digital output and on-chip timing control. The chip uses a Bayer RGB colour pattern, with colour reconstruction accomplished outside the sensor.
