A Development of View_Aid System for Low-Vision

We have been developing a portable system to verify the life environment without support of other people. We call this View-aid system. View-aid system is used when low-vision wants to verify the surroundings environment with the small wireless CMOS camera. The image that is taken with this camera is transmitted to the PDA with the analogue signal of 1.2 GHz band. It is received by the receiver, and the analogue signal is converted into digital and it sends to the PDA with a USB connection. We have developed the function of reading out headline in life space with view-aid system. The system has a function of detecting headline-block in the taken image. The target is headline in newspaper. The success rate of detecting headline algorithm is 77%, and the success rate of the headline character recognition is 45%. Moreover, to aim at further miniaturization of system device and at improvement of picture quality, we have examined a Bluetooth transmitting method for digital wireless.
