Abstract

Ensemble lentille (21), caméra (2) et terminal se rapportant au domaine technique des terminaux. La qualité et le rendement de l'ensemble lentille (21) peuvent être améliorés. L'ensemble lentille (21) comprend de multiples unités d'ensemble lentille (211) agencées en séquence depuis le côté objet de l'ensemble lentille (21) vers le côté image de l'ensemble lentille (21) ; chaque unité d'ensemble lentille (211) comprend un barillet de lentille (2111) et un groupe de lentilles (2112) installé dans le barillet de lentille (2111) ; la direction axiale du barillet de lentille (2111) est cohérente avec la direction d'agencement des multiples unités d'assemblage de lentilles (211) ; le groupe de lentilles (2112) comprend au moins une lentille (21121) disposée dans la direction axiale du barillet de lentille (2111) ; la distribution de résolution de l'ensemble lentille (21) satisfait une condition de distribution de résolution prédéfinie ; une structure de fixation (212) est disposée entre chaque paire d'unités d'assemblage de lentilles adjacentes (211) ; la structure de fixation (212) est utilisée pour fixer les positions relatives de deux unités d'assemblage de lentilles (211) adjacentes. L'ensemble lentille (21) est utilisé pour la caméra (2) dans un terminal.
