Abstract

trata-se de métodos e sistemas para engatilhar o foco automático. em um exemplo, um sistema pode incluir uma lente, um componente de memória configurado para armazenar parâmetros de lente da lente e regiões de foco que correspondem aos parâmetros de lente, e um processador acoplado à memória e à lente. o processador pode ser configurado para focalizar a lente em um objeto-alvo em um primeiro instante de tempo, receber indicativas de distâncias de um dispositivo de imageamento até o objeto-alvo em um período de tempo, obter parâmetros de lente da lente, e determinar uma região de foco, e engatilhar a lente para focalizar novamente no objeto-alvo se a distância até o objeto-alvo indicar que o objeto-alvo está fora da região de foco e a distância até o objeto-alvo é inalterada por um período de tempo designado.
