We have developed an LSI especially suited to process image signals (Image Signal Processor (ISP)). It can process signals of a gray-scale image having 256 levels as rapidly as TV images are scanned. The device features a kernel size which can easily be extended by either of two methods. The extension method adds ISPs like building blocks. For example, using four ISPS, a 4 × 4 spatial convolution for reconstruction of a gray-scale image composed of 256 × 256 pixels takes 1.9 ms; the second method adopts our newly proposed image scanning system, the stick scanning system. This enables one ISP to execute a 4 × 4 spatial convolution. In addition, various image processing operations can be done by changing the contents of the programmable control registers within the ISP. Our ISP is fabricated using 3 µm CMOS technology and comprises about 61,000 transistors. The chip is 7.72 × 8.64 mm in size and is mounted in a 64-pin DIP. [ABSTRACT FROM AUTHOR]
