The 720p/1080i HD Multi-Format Camera
Able to record in the 11 HD formats listed below, the AJ-HDX900 can produce content for use virtually anywhere in the world. And with its versatile features, the AJ-HDX900 can be used to produce virtually any kind of HD video content ? TV programs, music videos, stock footage, corporate video and much more.
The 2/3" 1-million-pixel IT 3CCD system delivers superb HD imagery combined with exceptional sensitivity of F10 at 2,000 lux. The AJ-HDX900 can capture outstanding shots in lighting as low as 0.032 lux (at +62 dB gain). The native progressive video format, which drives the CCDs continuously in progressive mode, outputs high-quality HD images that are suitable for use in filmlike production or in combination with computer graphics.
In the AJ-HDX900, we offer a 14-bit A/D conversion system, an upgrade over a conventional 12-bit system. We also incorporated a new high-performance digital signal processing (DSP) circuit. The 12-axis color correction matrix lets you make fine adjustments in specific color regions. Functions such as skin detail let you further fine-tune the image.
We also added a new Filmlike gamma mode called Filmlike 3, to the popular Filmlike 1 and Filmlike 2 gamma modes found in the AJ-SDX900 and AJ-HDX400. Filmlike 3 produces a film-like texture that makes images more emotionally expressive. This makes Filmlike 3 a good choice for certain TV programs, music and video clips, and other content.
Designed to broadcast specifications, the DVCPRO HD codec combines a video bit rate of 100 Mbps with 4:2:2 sampling and intra-frame compression. This reliable recording system also minimizes quality degradation with fast-moving subjects and is highly resistant to drop-out. The DVCPRO HD-LP format allows 33 minutes of recording on a medium-size cassette with reliable 1/4" metal particle tape.
DRS further extends the auto knee function. It recognizes the average brightness of highlight and shadow areas and then automatically adjusts the aperture and uses knee control to suppress blown highlights in the shadow areas. In scenes with mixed dark and light areas, such as when moving from indoors to outdoors, DRS automatically provides a wider dynamic range with minimal blown highlights and blocked shadows with no need to manually tweak the camera for each specific condition.
The AJ-HDX900 provides an easy-to-use, pushbutton super gain function with a maximum gain of +36 dB. In addition, it introduces a new digital super gain (in cumulative mode) utilizing the variable frame rate technology of Varicam and allowing an extra gain of +20 dB (at 6 fps). Unlike conventional gain adjustment, digital super gain is virtually noise-free*, so picture quality is preserved intact. With super gain and digital super gain, the AJ-HDX900 allows ultra-high-sensitive shooting at up to +62 dB. *At maximum gain (+62 dB) there may be a slight amount of noise.
The AJ-HDX900 can record full 48-kHz/16-bit digital audio on all four channels. You can freely select the audio source for each channel, choosing from mic, line, wireless receiver, and others. A 5-pin XLR jack with 2-channel compatibility is used for the front mic input. Using the AJ-MC900G optional stereo microphone lets you record stereo with a single mic.
