LG in 3D. Hands-on LG Optimus 3D and Optimus Pad
14 February 2011 by Olav Hellesø-Knutsen
LG has announced two handhelds capable of recording 3D videos. The Optimus Pad and the LG Optimus 3D
Both the Optimus Pad and Optimus 3D has two cameras, and both are capable of recording video in 3D, but only the Optimus 3D smartphone has a screen capable of showing the 3D media back to the user.
LG Optimus Pad
LG Optimus Pad is also called G-Slate in the US. The G-slate and Optimus Pad has the same hardware except a printed T-Mobile sticker on the back of the G-Slate.
LG Optimus 3D is the world first mobile phone capabel to both record and display 3D media on the device itself. The 3D recording is done using two lenses on the back of the phone
The Optimus 3D is powered by a 1GHz OMAP4 dual-core CPU and four times mode video decoders than competing designs, doubles the graphics performance of its nearest competitor. Recording in 3D using two lenses is no magic, being able to display media to the user without using glasses is. LG has solved this by using a stereoscopic LCD where an extra glass is placed on top of the usuall LCD display. The extra layer of glass split the images directionally into the viewe's eyes. The effect is only visible when the phone is held horizontally, and the effect will disappear if the angle of the display is wrong.
The optimal way of viewing 3D media on the phone is by holding the phone 30-40 cm from the user. It is also possible to simmulate 3D with regular images files using a SIM 3D application. A couple of 3D games are included where Golf 2 is one of them.
3D images captured are saved a JPS (jpeg stereo) where the image is vertically split in two and the two cameras has captured a left and right version of the image.
The Optimus 3D is also the first phone where 3D videos can be share on YouTube.
A dedicated 3D key is placed where you usually find the shutter button. Optimal distance for recording 3D is 0.5 to 3 meter. Recordings captured outside these limits will not experience much 3D look.
