A 48 x 48 pixel detector array and a 24 x 24 processing element array are monolithically integrated on the present focal plane array chip, which has been designed for real-time general purpose image processing. This analog CCD-based VLSI chip operates in the charge domain, and encompasses sensing, storing, and computing capabilities. The chip, which was fabricated in a commercial CCD foundry, is digitally programmable, and can implement such preprocessing tasks as level-shifting, gain adjustment, thresholding, smoothing, sharpening, and edge-detection. Such frame-to-frame operations as motion detection and tracking can also be implemented. Performance predictions have been obtained on the basis of a numerical analysis of prototype experimental results.
