8Chapter 1 IntroductionThe AJ-SPX900E memory card camera-recorder integrates a camera unit equipped with three CCDs, incorporating a 2/3-inch on-chip lens featuring progressive drive technology, and a video recorder/player (VTR) that supports DVCPRO50, DVCPRO and DVformats.The camera offers a choice of interlaced scanning and progressive scanning modes. The AJ-SPX900E provides for a wide range ofuses, with such features as film-like gamma correction capability for authoring, and storage-type gain-up capability for news pictureshooting.Utilising P2 cards, which require no mechanism, as media, your AJ-SPX900E offers greater responsibility, operability, and portability.It is highly resistant to shock and vibration during recording, and therefore ensures stable operation for capturing quality video imagesunder the most adverse conditions.1-1 Camera Unit Features/ Three CCDs with a 2/3-inch on-chip lens thatsupports progressive scanningThe camera supports aspect ratios of 16:9 and 4:3.Operators can choose between interlaced scanning andprogressive scanning modes, to handle a wide range ofapplications.In progressive scan mode, signals from and to the recorder/player are converted to interlaced signals./ Innovative 14-bit A/D Converted Digital SignalProcessing CircuitThis model utilises new 14-bit linear A/D conversiontechnology to digitise video. The signal processor, operatingat 36 MHz, provides finer reproduction of video, togetherwith enhanced stability and reliability./ Storage-type Sensitivity EnhancementThe camera unit is equipped with a storage-type gain-upcapability featuring progressive drive technology. Thiscapability adds up to 20 dB to the standard gain increase./ Digital ZoomThe camera unit features progressive digital zoom. This isparticularly effective when you want to zoom-in closer on thesubject./ 12-axis Independent color CorrectionOperating as a paint function, this capability independentlycorrects colors for each of the 12 axes. This feature helps toproduce fine images./ Film-like Gamma CorrectionThis capability provides a choice of four gamma types. Inaddition to the standard mode, two types of film-likegammas are available to help enhance video expression inproductions. The newly developed News Gamma accuratelyrecords changes in shadow areas and reduces whiteout inhighlighted areas. This is particularly useful for on-site newsshooting.While your AJ-SPX900E supports progressive scanning,constantly increasing the storage-type gain causes a slightdegree of brightening at the upper left corner of the screendue to CCD characteristics. Note also that the dynamicrange of video signals in progressive scanning mode isabout half that in interlaced driving mode./ Auto White Balance with Automatic TrackingcapabilityThe white balance is automatically adjusted in real time,according to the subject. This is effective for urgentrecording, where you can’t spare the time to make anadjustment through the auto white balance feature./ Data Management CapabilityYour AJ-SPX900E has inbuilt data storage capacity for oneuser and four scene files. In addition, an SD memory cardcan be used as a setup card to store data for up to eightsetups.Regarding SD memory cards, please also see using SD memory cards> (page 18)./ Customisable USER Buttons and USER MENUThe camera unit has three USER buttons, operable by asingle press, to which frequently used function may beassigned. The on-screen menu is also customisable. Youcan create an original user menu screen by selectingfrequently used menu items. The menu thus created can bedisplayed with a single touch of the MENU button./ MARKER SELECT ButtonYour video camera-recorder has a button on the front thatallows you to view marker information on the viewfinderscreen. This is useful for checking the view angle duringshooting./ Support for ECUYour video camera-recorder supports the extension controlunit AJ-EC3E.ᤨࠫ
