Abstract

"CORREçãO ALFA PARA COMPENSAR A FALTA DE CORREçãO GAMA". Os coeficiente de combinação (valores alfa) de grifos da fonte suportam a correção alfa para compensar a falta de correção gama nos processos de produção de texto. A correção alfa inclui selecionar um conjunto de coeficientes de correção que correspondem ao valor gama pré-determinado do dispositivo de exibição e calcular os valores alfa corrigidos a partir de valores alfa conhecidos, das cores de primeiro plano e do conjunto de coeficientes de correção. Os valores alfa corrigidos podem então ser utilizados para combinar as cores de primeiro plano e de segundo plano dos pixels de exibição correspondentes sem requerer a correção gama. Por conseq³ência, a correção alfa pode ser executada por uma GPU, a qual não está configurada para executar a correção gama, desse modo aumentado a velocidade na qual a produção do texto pode ocorrer.
