Abstract

um dispositivo de detecção de lâmpada detecta (21) uma porção de borda (31a, 31b) de uma imagem de câmera, a porção de borda tendo uma diferença de luminância igual ou superior a um valor predeterminado, e gera (22) uma imagem suavizada diminuindo a diferença de luminância da porção de borda. em seguida, o dispositivo de detecção de lâmpada extrai (24) pixels sincronizados da imagem suavizada, os pixels sincronizados tendo luminâncias variando de forma síncrona com um ciclo de corrente alternada de energia fornecida a uma lâmpada e detecta (26) a lâmpada a partir dos pixels sincronizados.
