Generating 3D images from 2D images

Many 3D movies have already been shown commercially at movie theaters. The demand for 3D image content

will soon reach the mass-market, especially the home consumer market, as 3D-compatible monitors are

released for consumers and BD players become more popular.

Much new visual content must be made to be 3D-compatible as 3D-viewing environments become popular

and content demand acutely increases. Moreover, it can be expected that the market will demand 3D versions

of current 2D content. The conversion will be hard work for content suppliers.

This unit generates 3D images by real-time conversion of 2D images shot and recorded using existing methods

and formats using a conversion technology based on an original JVC algorithm.

Below is a system structure example using the unit.

What is a 3D image?

A 3D image is an image which looks as if it has depth

though it is displayed on a flat surface; it gives you

stereoscopic visual impression which ordinary pictures

cannot offer. You see something really come out of the

screen or you seem to go actually into it.

On a current standard 3D imaging system, it is required

to process two video signals for the left and right eyes

and display them on a 3D-compatible special monitor to

create 3D images.

Real time 2D-3D image conversion

Video signals of existing 2D content in HD SDI, the

standard format for the video industry, or HDMI, the most

popular format for video recorder/player connections, are

taken in to the unit and converted into 3D images which

are then output to a 3D-compatible visual device in HD

SDI or HDMI format.

The 3D signals processed by the unit can be output

separately as left and right HD SDI signals. It is very

convenient for 3D image post production.

Various functions for 3D image adjustment

The stereoscopic effect is based on the differences

between images the left and right eyes see, so fine

adjustment of the left and right image is indispensable

for producing quality 3D images.

This unit is equipped with two functions for adjusting the

stereoscopic effect – parallax adjustment and intensity

adjustment – and you can adjust the two parameters

while monitoring images in any of the three display

methods: normal, anaglyph and LR sequential.

Selecting a 3D mixing format

A 3D image is realized by viewing a picture on a 3D-compatible monitor through special glasses with shutters
or polarized filters. The monitor displays images for the left and right eyes at the same time. Each lens produces
an image for the left or right eye only and the eyes see them as a stereoscopic image.

The unit is compatible with four 3D image formats, LINE BY LINE, SIDE BY SIDE H, ABOVE-BELOW and CHECKER
BOARD, that allow for various usage.

The unit executes conversion into any one of the four formats above in real-time.

●

Selectable formats vary depending on the type of input signal.

●

Selectable formats vary depending on the compatibility of the connected devices. Refer also to the instruction
manual or specifications of the connected device to check the compatibility.

Displays image stripes of the left and right images line by line one after another.
You can maintain the same horizontal resolution as the source when using a monitor with a polarized
filter system.

●

It is recommended to use another format if you use compression for recording images.

Shrinks the size of the left and right images by half and displays them side by side.
The format is compatible with most recent 3D -compatible displays. This format is very convenient
because of its high compatibility with existing recording and transmission systems though the
horizontal resolution is reduced to half.

Shrinks the left and right images by half vertically and displays them top and bottom.
The vertical resolution is reduced to half but the horizontal resolution is free from degradation if you
use a monitor with polarized filter system.

●

The format is available only when MIX is selected both in SDI OUT SELECT and HDMI OUT SELECT of

OUTPUT PRESET.

LINE BY LINE

SIDE BY SIDE H

ABOVE-BELOW

CHECKER BOARD

Displays image blocks of the left and right images one after another in a grid-like pattern.
This is an advanced format, which can reduce the feeling of image deterioration.

●

It is recommended to use another format if you use compression for recording images.

Adjusting the stereoscopic effect –

Intensity, Sub-intensity

You can control the engraving-like effect and the feeling of depth of an image by adjusting two types of
intensity: the curvature using scene detection, and the concavity and convexity using color detection. You can
adjust the image in total using the intensity adjustment, then you can adjust it partially using the sub-intensity
adjustment.

●

See page 06 for the detail of the adjustment.

Adjusting the stereoscopic effect –

Parallax

The stereoscopic effect is based on the differences between the view of the left and right eyes (parallax). This
unit can adjust degree of parallax to control stereoscopic effect.

●

See page 06 for the detail of the adjustment.

Adjusting the stereoscopic effect –

monitoring method

You can select a monitoring method when adjusting the stereoscopic effect of a 3D image. In addition to
ordinary 3D representation, anaglyph (the left and right images are colored differently) and LR sequential (the
left and right images are displayed alternately) are available for monitoring and adjusting parallax and intensity.

Setting

Follow the steps below to select a monitoring method.

Press ADJUST MODE and select a setting value using .

Anaglyph

Images for the left and right eyes are colored in red and blue respectively
and displayed on one screen in layers. You can check parallax adjustment by
viewing the gap between the lef t and right images even on a 2D (conventional)
monitor or without 3D glasses.

●

Be aware that it is difficult to see the colors and stereoscopic effect

correctly in anaglyphic representation.

Images for the left and right eyes are displayed alternately at 0.5-second
interval. You can view images in this method on a conventional 2D monitor
but it requires training to see them as 3D images.
