A new smart optical sensor, the MAPP2200 is presented. It is based on fouryears ofpractical experiences with an earlier line sensor device, theLAPP1 100. Using a 256*256 array ofphoto diodes the new device is capable ofcapturing a fullimage. The chip includes circuitry for AID-conversion and digital image processing. The processor, being a line-parallel SIMD machine handles line data at a rate of 4 MHz. The device performs common early vision tasks such as filtering, edge detection, histogramming, correlation etcetera at rates of 10 -100 frames per second. Simpler tasks such as binary template matching can be performed at more than 1000 frames per second. The paper covers both hardware and software aspects of the new device.
We have constructed an addressable 256 x 256 photodiode sensor array together with an 8-bit A/D converter on the same chip. Such a digital camera is easy to connect to a computer where also the flexibility of the computer can be used to control the camera output. The sensor has been constructed in two versions, the first version was implemented with a 256 parallel bitslice image processor on the same die in a commercial project and the second as a separate addressable digital image sensor. The sensor was functionally fabricated in a 1.6 |im standard CMOS process where it required a total area of 96 mm2 and the first commercial samples are already delivered.Also when writing this an improved sensor version is under processing.
