A new smart optical sensor, the MAPP2200 is presented. It is based on four years of practical experiences with an earlier line sensor device, the LAPP1100. Using a 256*256 array of photo diodes, the new device is capable of capturing a full image. The chip includes circuitry for A/D-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, and correlation 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.
