Abstract

"MéTODOS E SISTEMAS PARA CONVERSãO EM MAPA DE BITS ASSIMéTRICA COM SUPERAMOSTRAGEM DE DADOS DE IMAGEM". São revelados métodos e sistemas para utilizar um número aumentado de amostras de dados de imagens, acoplados com a natureza separadamente controlável dos subcomponentes de pixel RGB, para gerar imagens com resolução aumentada em um dispositivo de vídeo (98), tal como um vídeo de cristal líquido. Os métodos incluem as operações de ajuste de escala (86) , de hinting (88) e de conversão de varredura (90). A operação de ajuste de escala (86) envolve ajustar a escala dos dados de imagem por fatores de um nas direções perpendicular e paralela ao riscamento RGB do dispositivo de vídeo. O hinting (88) inclui colocar os dados de imagem com a escala ajustada em uma grade que possui pontos da grade definidos pelas posições dos pixels no dispositivo de vídeo e arredondar pontos chave para o limite mais próximo do pixel total na direção paralela ao riscamento e para o incremento fracionário mais próximo na direção perpendicular ao riscamento. A conversão de varredura (90) inclui o ajuste de escala dos dados de imagem que foram sujeitos ao algoritmos de hints por um fator de sobreajuste de escala (92 ) na direção perpendicular ao riscamento. O fator de sobreajuste de escala (92) é equivalente ao denominador dos incrementos fracionários na grade. A conversão de varredura (90) também inclui gerar (94), para cada região dos dados de imagem, um número de amostras que é igual ao fator de sobreajuste de escala e mapear os conjuntos espacialmente diferentes de amostras para cada um dos subcomponentes de pixel.
