Panasonic AJ-HDX400E operating instructions Features of the camera unit

Chapter 1 General

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.

1-1 Features of the camera unit

≥E-cinema camera unit featured ≥ Data control function

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).

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.

≥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.

≥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.

≥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.
