Sony - Focus-Free High-Resolution Pico Projector Module

Sony has announced the development of an extremely sophisticated small-size projector module (Pico Projector Module), that can be used to project images from smart devices such as smartphones or tablets.

It uses an image processing system, independently-developed by Sony, that uses laser beam scanning (LBS) to create crisp, high-definition and "focus-free" projection regardless of distance, angle or projection surface.

The LBS uses a semiconductor laser as its light source, the laser beam is then reflected and controlled using an MEMS (Micro Electro Mechanical Systems) mirror to scan and project the image. It uses a video processor to control the video signal processing and image output.

By developing a video processor that precisely controls the semiconductor laser and MEMS mirror, Sony has achieved high-resolution HD image quality that surpasses VFA and WVGA, which are the current mainstream resolution for battery-driven pico projectors.

Resolution with this module is 1920 x 720 with aspect ratio 16:9. (Currently, modules mounted on battery-driven pico projectors use a panel system, which generally have VGA (640 x 480) or WVGA (800 x 480) resolution.)

This model can project clear 40-inch images from a distance of 1 meter and 120-inch images from a distance of 3 meters. Also, the optical technology in the projector has achieved a significant reduction in laser speckle noise, which had previously been a challenge for LBS systems.

Perhaps the most interesting feature is that the light-harvesting capability and directness of the laser beam ensure that the projected image remains in focus, regardless of the distance or angle from the projection surface.

  • Dimensions: 52.5mm length x 63.0mm width x 7.2mm height
  • Resolution: 1920 x 720
  • Aspect ratio: 16:9


Sony has not announced pricing or a release date but will have a sample product available sometime during 2014.

Sanwa Supply just released a new pocket-sized slick portable projector "400-PRJ020".

After connecting with an MHL compliant smartphone, the portable projector can project photos or movies on the wall in a room. Also, it has an HDMI terminal built-in so that a notebook PC or blu-ray disc player can be connected.

A large-capacity battery (3,400mAh) enables it to continue projecting for a maximum of 2.5 hours.

Beginning late last year, AkihabaraNews rededicated itself to conducting more in-depth, multimedia product reviews. It’s gone well: contributors and editors have doubled down, and both the results and response have been great (Thanks, readers!).

Aerial Burton has demonstrated an aerial 3D display, which can project text and images in mid-air.

"The biggest difference between our technology and other displays is, this is a screenless display. This is the only device that can show text and pictures in mid-air, without using a screen.

Akihabara-based company Thanko's new simplified projector for smartphone called "Sumaho de Theater" allows you to make your room a home theater at a reasonable price with no bulbs, no noisy fans, and no electricity.

Addtron Technology, a Japanese electrical appliances retailer, is going to release Taiwanese company Vivitek's mobile DLP projector - QUMI Q1 - in late August for about 26,000 yen.

ASUS unveiled the release of their palm-sized projector - S1 - for the Japanese market. It will be out on sale on July 25.

A projection technology called DLP technology is applied for the S1. Thanks to that, S1 reproduces colors better than usual LCD projectors and projects clear images with high contrast. It features an LED light source, 1000:1 contrast ratio, 30~100 inch screen size, 0.73~2.43m projection distance, and maximum luminance of 200 lumen.

 

2x3D, developed by the Shirai Lab at Kanagawa Institute of Technology, is a system that lets the same screen be viewed simultaneously by people who want to watch it in 2D and 3D.

Whereas conventional passive 3D systems use polarizing filters for both the left and right eyes, this system uses a special picture-generating algorithm. Pictures for the left eye can be seen with the naked eye and only pictures for the right eye need to be viewed through a polarizing filter.
