Explanation of termsOthers112LSQT1052Auto focusThe lens is moved forward or backwardautomatically to bring the subject into focus.Auto focus has the followingcharacteristics.≥ Adjusts so that the vertical lines of a subjectare seen more clearly.≥ Attempts to bring an object with highercontrast into focus.≥ Focuses on the screen centre only.Due to these characteristics, auto focus doesnot work correctly in the following situations.Record pictures in the manual focus mode.Recording distant and close-up objects atthe same timeSince the unit focuses on whatever is at thecentre of the screen, it is difficult to bring thebackground into focus when close-up objectsare placed in focus. When recording peoplewith distant mountains in the background, youcannot focus on both the subject which isclose-up and the objects which are in thedistance.Recording a subject behind dirty or dustywindowThe subject behind the window will not befocused because the focus is on the dirtywindow.Similarly, when recording something on theopposite side of a road with heavy traffic, avehicle that happens to pass by may bebrought into focus.Recording a subject that is surrounded byobjects with glossy surfaces or by highlyreflective objectsSince whatever is shiny or glistens is broughtinto focus, it is hard to focus on the subject tobe recorded. The focus may become blurrywhen recording subjects at the seashore, innight views or in scenes involving fireworks orspecial lights.Recording a subject in dark surroundingsThe unit cannot focus correctly because thelight information that comes through the lensdecreases considerably.Recording a fast-moving subjectAs the focus lens-inside moves mechanically, itcannot keep up with a fast-moving subject.When, for example, recording a sports eventwith fast moving subjects, the focus may loseits sharpness.Recording a subject with little contrastIt is easy to bring subjects with a sharp contrastor vertical lines or stripes into focus. Thismeans that a subject with little contrast, suchas a white wall, may become blurry becausethe unit achieves focus based upon the verticallines of an image.LSQT1052(ENG).book 112 ページ２００５年１２月２１日水曜日午後６時５０分
