Abstract
A communication system and method are described for transmitting data from a display in a bit transmission data format to a machine vision system. The described system and method allows for the process and further application of a larger amount of data faster and more reliably than by use of the human readable data from the display. A standard LCD screen displays bit transmission data corresponding to human readable data, and transmits the bit transmission data to a machine vision system, such as by use of the camera on a smart phone. The captured bit transmission data is converted into a bit data stream for further processing, such as by use of an application in the smart phone, and can be stored in memory and/or transmitted to another system to provide useful human readable information. Faster transmission of a greater amount of data is realized including, in one aspect of the bit generation, data error and correction codes. In one embodiment the method and system is applied in a body composition scale application using a four digit, 7-segment LCD.
