Introduction

A compact 3D camera with two parallel built-in lenses has resulted in “a new market” which differs from that of conventional movies and TV broadcasts and entered the world of 3D videos.The new market can be expected to steadily grow with the development of technology that mitigates visual fatigue resulting from stereoscopic viewing and technology used to process complex stereoscopic viewing data on a file basis.This Guidebook introduces the basic knowledge and features of 3D video and unleashes the potential of the production flow of 3D content.

Basic Knowledge on 3D

The distance between the two camera lenses, or the equivalent of left and right eyes, is referred to as the “Stereo base”. The width of the gap between the left and right images is referred to as the “Disparity”.Stereo base and Disparity greatly influence the stereoscopic effect. Basically, the bigger the Stereo base is, resulting from setting the two lenses further apart, the bigger the Disparity (left-right disparity in the image) is, and the stronger the stereoscopic effect.Conversely, the smaller the Stereo base is, resulting from setting the two lenses closer together, the smaller the Disparity is, and the milder the stereoscopic effect.<B>, the area where the optical axes cross and thus no disparity in images, is referred to as the “Convergence point”, and is the 3D reference point.The following figures reveal how the Disparity becomes bigger as the Stereo base lengthens.

Both our eyes are slightly apart from each other, and hence everything ‘seen’ by our brains has a small left-right disparity. Our brains actually then instantaneously judge the perspective according to that left-right disparity, thus providing us with a stereoscopic view.Basically a stereoscopic view video is realized through capturing images from both the left and right with twin lenses, just like our eyes do, and then showing the images independently to our left and right eyes.

Toe-in setting

The shooting method used to cross the optical axes over by setting the left and right lenses slightly inside, as explained on the preceding page, with the advantage of the method being that zooming does not change the Convergence point. However, a disadvantage of the method is the occurrence of “trapezoidal distortion” in the logic due the optical axes crossing over each other. When the Stereo base is wide and the convergence angle (toe-in angle) therefore large the difference in size and unevenness between the upper and lower sides becomes quite conspicuous at both ends of the left and right displays, thus requiring adjustment.

Shooting method of two-lens 3D cameras

The methods used with currently available 3D cameras equipped with two lenses include “Toe-in setting” and “Parallel setting”, whose individual features differ from each other.

Trapezoidal distortion in the lattice patterns shot using the Toe-in setting

Virtua convergence point


Parallel setting (the method used with the HXR-NX3D1)

The shooting method used to make the optical axes parallel by setting the left and right lenses to be parallel.This method does not incur the trapezoidal distortion that occurs with the Toe-in setting.The optical axes do not cross as is, and hence infinity becomes the virtual convergence point, and all the objects move in the popping up direction. The left and right images therefore get shifted in parallel upon shooting in adjusting the disparity.*The optical axes do not cross in the Parallel setting and hence the Convergence point

with a “zero” disparity is defined as a “Virtual convergence point”

The Virtual convergence point is infinite and hence all the objects look as they are popping up.

Minimum object distance for 3D

The stereoscopic effect is represented by the amount of disparity, but an excessively large left-right disparity can ruin 3D images. Shooting 2D images is possible as long as they are in focus, whereas with shooting 3D images if the disparity is too big the physical burden during viewing can be too great. The minimum object distance thus needs to be secured in thereby ensuring that 3D images can be shot in a viewer-friendly manner without being ruined.The following figures show the relationship between the zoom position and minimum object distance for viewing 3D videos taken by the HXR-NX3D1 on 40 ~ 60 inch 3D TV.

Visual difference in accordance with the viewing sizeThe stereoscopic effect can vary depending on the size of the screen used to view the video.

• The bigger the screen size the bigger the proportionate disparity. The stereoscopic effect is further emphasized and the side that looks like a

concave image, in particular, can be easily ruined. The supported disparity is approximately 40 mm with a 60-inch monitor.

• The smaller the screen size the smaller the proportionate disparity. The smaller the disparity is the more difficult it is to sense the stereoscopic

effect.

Recording of left and right 3D images in the MVC format of 1920 x 1080

The MVC (Multiview Video Coding) system is used as the recording format of 3D images and can record images as a single video stream at a resolution of 1920 x 1080 for both left and right eyes.

* MXR-NX3D1 supports recording of 1080/60i, 50i, and 24p. In addition, images can be separated into left and right images via use of the accessory software CMU (Content Management Utility).

Shooting 3D Videos

Disparity adjustment

Disparity can be adjusted by shifting the cutout area of an image being shot on the imager.By turning the adjustment dial in the + direction to move the cutout area to the outer side the Virtual convergence point moves to the back, thus increasing the pop up effect.

Compact

A very compact twin-lens 3D camcorder with a built-in 1/4 CMOS sensor and left and right 10-power lenses. The small distance between the left and right lenses (Stereo base: Inter Axial Distance) of 31 mm and parallel setting of the lenses 3D videos to be shot quite close to the subject.

Functionality optimized for 3D shooting in thus avoiding any blurred images due to hand movements

Active SteadyShot, or the technology used to correct any blurring of the images due to hand movements in the three directions that include the turning direction in addition to up, down, left and right, can be activated during 3D shooting, thus ensuring stable 3D images of moving objects.

3D L+R MIX(2D)

R (2D)L (2D)


Liquid-crystal panel supports glassless 3D display for use in checking stereoscopic images on the spot

The HXR-NX3D1 is equipped with a 3.5-inch liquid-crystal HD panel of disparity the barrier type at 1,229,000 pixels (2562 x 480). The panel thus provides high-resolution stereoscopic viewing on the spot while supporting the disparity adjustments which are so critical to 3D video shooting.

How to utilize the liquid-crystal panel while shooting images

1. First, decide the composition using the 2D L or R.

2. Next, adjust the disparity by checking the amount of disparity using the L+R MIX before deciding upon the Virtual convergence point.

3. Switch to 3D display and check the extent of the actual popping up and concave effect. Repeat steps 2 and 3 as needed.

4. Shoot the image in 3D or L/R of 2D after the disparity adjustment has been completed.

1* Ensure a 30 cm distance from the liquid-crystal panel and look at the panel from the front for how the 3D displays.

* The left-right disparity can be checked using the L+R MIX, which displays the left and right images vertically in turn.

NG! Too much popping up

The distance between the camera and object being too close will result in the object having “too much of a popping up” effect. With this situation the object at the nearest side appears to have double and the 3D image to have failed.

NG! Too concave

The object being too far away from the screen will result in “too much of a concave” effect.In this case not only the stereoscopic effect is lost but also viewers will incur headaches from excessive eye squinting from attempting to view the image with both their eyes pointing outwards.

How to resolve this problemShoot using an angle where infinity does not overly stand out by making the effort to exclude the ruined image.

Method of adjusting the disparity in preventing 3D images from being ruined

How to resolve this problemWith the HXR-NX3D1 the Virtual convergence point should be set to the nearest side in the disparity adjustment by setting the image angle to the widest and ensuring a distance of more than 80 cm from the object. This then results in the disparity of the closest object being smaller.

* Adjust the disparity to be within 30 - 50 pixels by checking the image in L+R MIX mode.

NG! Blurring of images due to movement of the hands

Blurred 3D images resulting from hand movements are difficult to view than blurred 2D images and can increase the chance of it being unpleasant to view.

How to resolve this problemActivate the HXR-NX3D1 “Active SteadyShot” feature.This function interlocks the left and right lenses, thus providing more intensive correction of any images blurred by movements of the hand. The function thereby enables more stable 3D shooting of moving objects.

Caution! Zoom & pan

Movement of the lenses while shooting images can result in problems with 3D shooting that never occurred with 2D shooting. Slow panning can result in a difference in the left and right images, thus leading to a stereo window violation.In addition, the Virtual conversion point can misalign during zooming.

How to resolve this problemThe recommended solution is to avoid frequent use of zooming and panning to fully obtain a stereoscopic effect in 3D images. If zooming and panning are used then you will need to check for any stereo window violations or misalignment of the Virtual conversion point.

Notes on Editing 3D Videos

Longer cut times!

Cut times that bring out the fullest stereoscopic production effect

Viewers typically take a few seconds to recognize the stereoscopic relationship of any objects included in the image that are based on a disparity.Viewers therefore cannot recognize any stereoscopic effect in fast-moving scenes with many cuts over several frames.Set longer cut times for any scene in which you wish to emphasize the 3D effect.

Caution!

When linking compositions of different disparities

Conventional 2D images maintain the relationship between the left and right positions using an imaginary line. However, the Convergence point is used in 3D images as the imaginary line for the front and back, with the relationship between the front and back positions of the objects needing to be maintained.When moving the camera position you should pay attention to the relationship between the front and back of the objects, and taking the relationship between the Convergence point and the object positions into consideration.

When linking the withdraw cut to the approach cut images whose disparity is significantly different should not be combined. With images shot from the same position, in particular, unpleasant shocks can be prevented by keeping the apparent convergence in a constant position, even if you do change the size.

Do not mix!

Screens of different disparity on a multiscreen

The screens on PinP or a multiscreen being of individual disparity will result in the viewer being unable to look at all the screens in 3D at the same time.Set all the screens to a similar level disparity or create the screens in 2D.

*If a number of screens are displayed the individual disparity can be ignored as long as each screen size gets smaller.

Avoid!

Transition that divides the Disparity

Transitions such as slides and wipes divide the normal disparity during the transition effect. Because of this no transition should be used as the stereoscopic viewing will be ruined in the middle of the effect. Other transitions where a pseudo 3D effect is created in 2D will look unnatural because the 3D space has no disparity.

A longer dissolve can change the amount of disparity during the effect and produce a stereoscopic effect for forward and backward movements.

Organize!

Amount of popping up of a title

Lay out the title text nearest to the image by arranging it to be a constant amount of popping up. If any object is near the text it will look like its cutting into the object. In addition, if the amount of popping up of the text varies in every cut viewers will incur eye strain because the Convergence point will constantly changing while they read the text.Note that large disparities will tire viewers when the distance between the background and the text in the front is large.

You can produce a great impact for the title utilizing the 3D effect. Dynamic expressions can be produced via effective control of the changes in size and disparity.

About 3D video format for output in 2D format

The side by side format displays left and right pictures in one screen by changing the horizontal aspect ratio. The top and bottom format displays left and right pictures in the upper section and lower section, respectively, by changing the vertical aspect ratio. The line by line format displays left and right images via alternate allocation in the vertical fields.By transferring the left and right images at a 2D HD resolution after compressing them in half enables 3D videos to be output with conventional 2D reproduction equipment.

About the types of 3D TVs, monitors, and glasses

FAQ

■ Polarized seal + circular-polarized glassesThe left and right images are allocated to even-numbered and odd-numbered fields and polarized with the lens on the side of glasses. The glasses are handy to use because they need no electricity but they do halve the resolution.

FAQ

■ Frame sequential + Active shutter glassesElectrically opened/closed shutters are equipped on the left and right lenses of the glasses for use in switching the left and right images of every frame in synchronization with the monitor. The shutter on each of the left and right lens open/close 30 times per second, the combination of which provides the clear images.

■ Glass-less 3D displaysGlass-less 3D displays show different images to the left and right eyes using one screen by overlapping plate lens called “Lenticular lens” or a vertical-striped filter (Aperture grille) called a “disparity barrier” on a regular display.

* The HXR-NX3D1 utilizes the Disparity barrier system.


What are the advantages of a twin-lens 3D camera?

• The distance between the left and right lenses can be decreased, thus enabling 3D to be shot closer to the object.

• Two cameras take longer to set and are more difficult to adjust.• With the HXR-NX3D1 you can accurately interlock the left and right lens

mechanisms, including zooming and adjusting any blurring of the images due to hand movement. Stable 3D images of even moving objects can thus be created.

Camera

When shooting a large object at a distance

Obtaining the 3D effect for large objects far away from the camera can be difficult, and you need to increase the distance between the left and right lenses. Twin-lens 3D cameras do not support large distances between the left and right lenses, and hence two cameras using a rig that keeps the cameras in parallel is needed.

Shooting

Something strange appears in the images upon zooming (With HXR-NX3D1)

One of the reasons for that could be a misalignment in the optical axes of the two lenses. Perform [Auto 3D Lens Adjust] to realign the upper/lower position of the screen during shooting.

Notes for conversion into 2D images using CMU (Content Management Utility)

When the files separated into left and right images using CMU (Content Management Utility) are played back with editing software the final end left and right frames may mismatch. (The top frames will always match.)When you use separated left and right files as a pair you should not use the files all the way to the end and instead set the out point to be a few frames back.

About MVC (MPEG4/H.264 MVC)

MVC (Multi View Coding) is an extension standards added to H.264/AVC Version 11 for compressing images shot from several points of view into one stream.MVC allows encoding via the composition of a reference base view and a non-base view while referring to other views and frames included in itself (inter-view prediction), thus providing more efficient compression.MVC is suitable for the compressing 3D images that require recording of images from left and right points of view. MVC is also used in Blue-ray 3D standards.MVC has backward compatibility with the H.264 and thus allows existing 2D AVC/H.264 decoders to decode the base view only.

*MVC files recorded with the HXR-NX3D1 can be used as the base view, or, that is 2D images for the left point of view, in some cases, by importing the MVC files to AVCHD compatible non-linear editing software. However, this is not guaranteed to work.

Posting 3D images on YouTube

You can post videos created beside each other on YouTube.YouTube automatically converts video files into the anaglyph format for play back, thus making a dedicated 3D monitor unnecessary. Viewers can therefore use anaglyph glasses and a standard PC monitor to watch 3D videos.
