Panasonic AG-3DA1 Integrated Twin-lens 3D Camera Recorder
|The Integrated Twin-Lens 3D Camera Recorder Accelerates 3D Video Production
Real-life 3D images are expected to find widespread application in fields ranging from movies and TV broadcasts to industrial and educational uses. In response to the rapidly growing
needs for 3D image production, Panasonic now offers a revolutionary solution: AG-3DA1 the integrated twin-lens FULL HD 3D camera recorder.
The Panasonic AG-3DA1 features a camera section with two integrated
lens systems that are configured to resemble the human eyes, and a recorder section that records left-channel and right-channel full-HD images using the high-quality PH mode of the file-based AVCHD format. With the same approximate weight and size of a 2D camera recorder, the AG-3DA1 is easy to handle. It's also quick to operate, as it doesn't require any adjustment of the left and right
lens alignment such as vertical gap, size difference, rotation and luminance difference.
The Panasonic AG-3DA1 frees the user from the kind of complex, cumbersome
procedures of a conventional rig-type 3D camera system. Data files recorded onto a memory card are readily processed using a nonlinear editing system. With its excellent mobility , flexibility and low
cost operation, the AG-3DA1 opens the door to 3D image production
Schematic of the AG-3DA1:
The Panasonic AG-3DA1 left-channel and right-channel optical sections, image sensors, signal processing circuits and recording section are precisely synchronized. The AG-3DA1 outputs
left-eye and right-eye full-HD image signals as simultaneous HD-SDI video and also records to the SD/SDHC memory cards in the AVCHD format.
|Twin Lens System
The high-precision HD twin lens system allows easy acquisition of natural looking 3D images
The Integrated Structure Revolutionizes Mobility for Nimble Camera
The Panasonic AG-3DA1 Conventional rig-type 3D camera systems are large and heavy because they mount two existing cameras onto a robust frame. They also require a
separate recording system and power supply unit, which makes the cable connection complex and restricts the location and the type of camera work. As a result, the scenes that can be acquired with a
rig-type 3D camera system are limited. The compact body of the AG-3DA1 integrated twin-lens FULL HD 3D camera recorder weighs only 2.4 kg (5.3lb). AG-3DA1 offers the same portability and mobility as
a conventional 2D camera recorder for flexible image acquisition. The AG-3DA1 enhances camera work for all kinds of 3D image production.
The Twin-Lens System Sets You Free From
Complex Camera Adjustments for 3D Images
To achieve natural-looking 3D images, you need to pay close attention to the following key points for left- and right-eye
images: (1) Vertical deviation, (2) Angle deviation, (3) Difference in brightness and color, (4) Rotation error, (5) Correct adjustment of the convergence, (6) Appropriate image composition. With a
conventional rig-type 3D camera system using two separate cameras, these adjustments have to be made precisely for each and every scene. The two integrated optical systems of the AG-3DA1 eliminate
the need for manual adjustments of (1) through (4), because they're performed entirely inside the camera recorder.* The optical systems are assembled with high precision, and the lenses, image sensors
and signal processing circuits for the left and right systems are accurately synchronized (see the diagram on the previous page). The AG-3DA1 lets you concentrate only on the convergence adjustment and
*Fine adjustments of the vertical position, focus and iris are also possible.
HD Twin-Lens with No Adjustment for Image Acquisition
Panasonic AG-3DA1 The distance
between the two lens axes is approximately the same as the distance between the human eyes, to provide easy-to-view, natural-looking 3D images. The HD twin-lens system is set with a distance of about 60
mm (2.3 inches) between the two lenses. The lens axes, viewing angle, rotation, and gradation are pre-adjusted before the components are precisely assembled. This eliminates the need for
lens adjustment before shooting. Camera operations such as focusing, zooming and iris adjustment are also synchronized for the left and right lenses.
The new twin HD lenses were designed exclusively for FULL HD 3D image acquisition. They boast low chroma aberration and high resolution, and deliver superb color reproduction, detailed nuances
and crisp 3D images even in dark scenes - with minimal flare and ghosting. A built-in 5.6x (approx.) optical zoom function, which extends from 47.1 mm (35 mm equivalent) wide angle to 264 mm (35 mm
equivalent) telephoto, covers a wide viewing angle that is well matched to 3D content production.
Convergence Point Adjustment Function
AG-3DA1 The convergence
angle between the two lenses is varied inside the optical unit. This moves the convergence point (the reference plane of the 3D image) in a fore-and-aft direction to control the leaping and depth
effects of recorded objects, and acquires natural-looking 3D images. The AG-3DA1 convergence point can be adjusted easily by using the CONV (convergence) dial* while viewing the L/R-MIX image
on the LCD monitor.
*The dial function is switchable between CONV (convergence) adjustment and IRIS (iris) adjustment.
Display Functions Assist 3D Image
The LCD monitor and viewfinder of the AG-3DA1 both display a variety of information to
assist 3D image shooting and ensure superb 3D effects.
• 3D Guide: This displays numerical values for the distance range of the subject to achieve better 3D effects while viewing.
Natural-looking 3D images can be captured by using the displayed information as a guide. This function offers two modes: Guide Display 1 mode assumes playback on screens that are 196 cm/ 77
inches or smaller, and Guide Display 2 mode is designed for a screen size of 508 cm/ 200 inches.
• Convergence Point: This displays the numerical value of the
convergence point together with the 3D Guide to assist adjustments.
• L/R-MIX Monitor Image Selector: The image display on the LCD monitor and viewfinder can be selected from three modes: Left
Lens (no mode indication), Right Lens (R-IMAGE) and Left/Right Mix (MIX).
*When the subject is located outside the distance range indicated by the 3D Guide, it may result in a double image or an unnatural
image without proper 3D effects.
Dual 3MOS for High-Quality FULL HD 3D
The AG-3DA1 is equipped with two 1/4.1 type 2.07-megapixel (approx.) 3MOS units for left- and right-eye images. Full-pixel full-HD left- and right-eye images
are accurately synchronized to create FULL HD 3D images.
