DA8223 real-time 2D to 3D video and still image
conversion
General Description
DA8223 is a single-chip 2D to 3D converter IC that converts 2D video
and still images into vibrant 3D in real-time. DA8223 unlocks a world
of 3D content providing consumers with an unbounded 3D experience
Compared with traditional software based solutions, DA8223 removes all loading
from the host application processor providing an ultra low power 3D converter
with no external memory requirement.
The chip includes a fully integrated parallax barrier driver which when connected to
a parallax barrier display, removes the need for 3D glasses allowing the viewer to see
3D directly.
DA8223 is ideal for battery operated handheld devices such as 3D smartphones and tablet PCs.
Converting 2D images to 3D
The DA8223 operates in real-time on the RGB image data typically provided by the host application processor. The conversion to 3D is a three
stage process:
1. Each 2D image (picture still or video frame) is converted into a depth map separating picture elements into foreground and background.
2. Each pixel from the original 2D image is assigned a depth tag identifying if it is located in the foreground or background. The perceived degree
of separation (shift) between foreground and background is realised by shifting the foreground pixels. The greater the shift, the deeper the 3D
effect will appear to the viewer.
3. The shifted pixel image is then processed by the image formatter. This aligns and synchronises each left and right eye pixel to the 3D display’s
parallax barrier filter with the resulting image appearing in 3D without the need for 3D glasses.
The whole conversion process has a latency time of less than one frame resulting in near-instantaneous 3D conversion. This super fast conversion
enables instant switching between portrait and landscape modes allowing the viewer to rotate the display at will.

... The DA8223 auto senses the start of each video frame and synchronise control of the parallax barrier filter ensuring it is in-step with the video. The parallax barrier can be switched on and off enabling the display of both 2D and 3D content. The DA8223’s dual driver can control 2 parallax barriers enabling 3D viewing in both portrait and landscape modes ...

... Native 3D mode. DA8223 passes 3D content direct from the host processor and synchronises control of the parallax barrier for 3D display mode. DA8223 is in full bypass mode passing 2D content from the host processor to the display with the parallax barrier switched off mode. DA8223 converts incoming RGB data to 3D and outputs to the display while synchronising control of the parallax barrier. ...
