This paper outlines methods of cost reduction and downsizing of an Image Processing Camera (IPCAM) intended for use in lane departure warning system or lane keeping system. These systems have potential needs in the society because they may be able to reduce fatal traffic accidents. But two issues are faced to solve before the popularisation of these systems. First one was how to reduce the cost of image-processing camera currently consisting of many expensive devices. Second one was how to improve the lane detection performance and the accuracy. The attempt to provide solutions to the above-described problems began with innovation of hardware architecture for image processing, based on the unique algorithm for lane detection. It has been realized that pre-processor for image processing and external memory were eliminated by the innovation. In addition, an adoption of 1 chip CMOS was realized by long exposure within those systems delay. Moreover it could materialize conversion from glass lens into plastic one. Then it has successfully devised the way to operate an image processing only with a general-purpose microcomputer and an image sensor. Now the volume of the camera is just 50 cm3. Compared with conventional ones, the image-processing camera is far smaller and of low cost. This paper is going to describe the revolutionary image-processing camera aimed for broad application.
