Abstract
MÉTODOS E EQUIPAMENTO PARA CONFIGURAR SENSOR DE IMAGENS PARA DECODIFICAR SINAIS DE COMUNICAÇÃO DE LUZ VISÍVEL DE ALTA FREQUÊNCIA. São apresentados um método, um equipamento e um meio passível de leitura por computador para configurar um sensor de imagens para processar um sinal de comunicação de luz visível (VLC). O equipamento instrui o sensor de imagens a funcionar em uma primeira configuração de exposição, a primeira configuração de exposição inferior a uma segunda configuração de exposição para captar uma imagem fotográfica, capta, por meio do sensor de imagens, pelo menos um quadro de sinal VLC na primeira configuração de exposição, detecta pelo menos um símbolo de comunicação incluído no pelo menos um quadro de sinal VLC captado e decodifica uma mensagem associada ao pelo menos um quadro de sinal VLC captado pelo sensor de imagens pela decodificação de vários símbolos de comunicação detectados.
