Abstract

"APARELHO PARA IDENTIFICAR AS QUATRO COORDENADAS QUE DEFINEM OS CANTOS DE UMA JANELA EM LTM MONITOR DE EXIBIçãO VISUAL". Aparelho para identificar as quatro coordenadas de uma janela em um monitor de exibição visual, o aparelho compreendendo dispositivo para obter dados digitais que correspondem a pixéis de uma imagem a ser exibida no monitor, uma memória arranjada para acomodar os dados digitais, um comparador arranjado para comparar os valores dos dados para pixéis horizontalmente e verticalmente adjacentes, dispositivo para gerar um valor de gradiente indicativo da diferença em luminância de pixéis adjacentes na direção horizontal e na direção vertical, uma memória para armazenar os valores de gradiente, dispositivo para detectar uma configuração exclusiva nos valores de gradiente para identificar as três coordenadas de uma borda da janela, e dispositivo para verificar na direção perpendicular à borda identificada para uma configuração correspondente exclusiva, para determinar a quarta coordenada da janela.
