Abstract
sistemas e métodos para zoom de câmera. são descritos exemplos de características de imagem de retenção de zoom digital como nitidez, clareza, e/ou contraste. em alguns aspectos, um dispositivo pode receber uma imagem e pode determinar várias pontuações de características de imagem correspondendo a variantes ampliadas digitalmente da imagem tendo diferentes intensidades de zoom. por exemplo, o dispositivo pode determinar uma primeira pontuação de característica de imagem para uma primeira intensidade de zoom e uma segunda pontuação de característica de imagem para uma segunda intensidade de zoom. o dispositivo pode comparar as pontuações de características de imagem a um limite de característica de imagem, e pode selecionar a intensidade de zoom mais alta para a qual a pontuação de característica de imagem correspondente não esteja abaixo do limite de característica de imagem. por exemplo, o dispositivo pode selecionar a primeira intensidade de zoom se a primeira pontuação de característica de imagem atender ou exceder o limite de característica de imagem enquanto a segunda pontuação de característica de imagem não. o dispositivo pode produzir dados de imagem correspondendo à imagem na intensidade de zoom selecionada.
