E-cinema camera unit featured
This video camera recorder features the Varicam (AJ-
HDC27F) camera unit that was developed for E-cinema
uses. This camera maximally exploits the excellence of
progressive scanning and, in delivering signals to the VTR
unit, it cross-converts the signals into the 1080i system
using a newly developed LSI chip.
≥ Progressive drive
The unit is a switchable progressive and interlaced
standards (1080/25P and 1080/50i) enable reader.
While progressive drive is used, the signals transferred to
and from the unit ae converted into interlace signais
(25PsF).
≥ Storage type high-sensitivity function
The unit comes with a storage type gain increase function.
This is a function that makes it possible to achieve a higher
sensitivity of up to 20 dB above the regular gain increase.
≥ Digital zoom function
The unit is equipped with a digital zoom employing function.
This function is particularly useful when zooming further in
on a subject.
≥ 12-bit A/D conversion digital signal processing
circuitry
The analog images are processed into digital data by a 12-
bit A/D converter with sampling frequencies of 74 MHz, and
by operating the signal processor using the 74 MHz
frequency, it is possible to reproduce images which are
more finely detailed and achieve improvements in stability
and reliability.
≥
12-axis independent color correction function
Serving as a paint function, this facility enables the colors
for 12 axes to be compensated for independently and is
very useful for creating finely detailed images.
≥ Data control function
When the unit is used on its own, one set of user data and
four sets of scene file data can be registered. Further, by
using an SD card or a Multimedia Card (optional accessory)
as the setup card, up to eight sets of setup data can be
stored.
<Note>
SD card and MultiMedia card used in this unit do not
comply with the SD standard. Do not use cards formatted
using this unit with other camera-recorders. Further, NTFS
and FAT32 formatted cards cannot be used with this unit.
The recommended size for SD cards is 8 MB or more and 4
MB or more for MultiMedia cards.
≥ MARKER SELECT button
At the front of the unit is a button for checking the
information concerning the markers on the viewfinder
screen. This is useful for checking the picture angle, for
instance, during shooting.
≥ ECU supported
The unit supports the AJ-EC3E extension control unit.
≥ Single-action shoulder pad slide function
It is now possible to adjust the position where the unit is
optimally balanced for operation using a single-touch action.
This means that the operator can easily optimize the unit’s
balance when the lens, battery and other peripheral camera
devices have been installed on the unit.
1-1 Features of the camera unit
The AJ-HDX400E is a video camera recorder that integrates a 3-CCD camera unit featuring a 2/3-inch on-chip lens that supports
progressive drive with a VTR unit that in turn supports the DVCPRO HD EX format.
One special feature of the camera unit is its ability to consistently express images with a high quality and high sensitivity since it
employs progressive drive.
The unit is both compact and lightweight, and it has a minimal power consumption. It features a high picture quality and
sensitivity, it has excellent mobility, and it effectively withstands dust, humidity and moisture. With all these features
incorporated, it can be used even for electronic news gathering activities.
Both the camera and VTR units employ digital signal processing technology to achieve even higher levels of picture quality and
stability and also to produce a system that enables the data to be controlled on the setup card.
