In recent years, the touchscreen is adopted as various electronic devices. However, on a flat touchscreen, for a vision disabled person, tactile feeling with the finger which is important information may not be obtained. Therefore operativity may be spoiled. We have proposed a wearable supporting system to operate a capacitive touchscreen for them. In a proposal system, an image sensor is equipped under the middle finger and an ear is equipped with the earphone for audio assists. And if a touchscreen is traced by the middle finger, the color barcode which the image sensor caught will be recognized, and the audio assist according to a result will be made. A user pushes an icon not by the middle finger but by an index finger, following an audio assist. In this paper, the hardware platform of the camera -control part in a proposal supporting system is developed. This platform consists of an interface with a camera or a host and an image processing part. The implementation result to FPGA showed that the interface was small and most resources could be used for an image processing part. The image from a camera was able to be displayed on the display through a fundamental verification of operation.
