Abstract

resumo método de autofocagem e dispositivo de autofocagem a presente revelação refere-se a um método de autofocagem e a um dispositivo de autofocagem. o método inclui: quando a focagem manual é terminada através da exploração de um objeto-alvo em um visor por um usuário, adquirir (101) os primeiros dados espaciais do objeto-alvo; quando detectar que os conteúdos de uma vista encontrada no visor mudam, adquirir (102) os dados de variação de posição; calcular (103) os segundos dados espaciais do objeto-alvo de acordo com os primeiros dados espaciais e os dados de variação de posição; e realizar (104) a autofocagem no objeto-alvo de acordo com os segundos dados espaciais. assim, a presente revelação pode evitar operações de focagem manuais quando os conteúdos da vista encontrada mudam, simplificar os fluxos de operação de focagem, aumentar a velocidade de focagem, e consequentemente melhorar a experiência fotográfica do usuário.
