Autofoco

Autofoco é uma tecnologia utilizada em câmeras para ajustar automaticamente o foco da imagem antes da captura de uma foto ou gravação de vídeo. O sistema analisa a cena e determina a distância dos objetos para produzir imagens mais nítidas. Nos smartphones modernos, o autofoco tornou-se cada vez mais rápido e preciso, contribuindo significativamente para a qualidade das fotografias.
