Sony has today unveiled a new Sony Pico Projector which is has designed to offer users with focus-free viewing thanks to it being equipped with Sony’s independently-developed image processing system.
The Sony Pico Projector uses laser beam scanning to keep its image in focus and is capable of projecting at high definition resolutions and focus-free regardless of the distance or angle from the projection surface and measures just 52.5mm length x 63.0mm width x 7.2mm in size.
Sony explains a little more about their new Sony Laser Pico Projector:
“This newly developed module is composed primarily of a semiconductor laser, MEMS (Micro Electro Mechanical Systems) mirror, their respective drivers, and a video processor to control the video signal processing and image output.
It adopts a LBS system that incorporates a semiconductor laser as the source of light, whereby the laser beam is reflected and controlled by a MEMS mirror to scan and project the image.
By developing a video processor that ensures the semiconductor laser and MEMS mirror can be controlled with the utmost precision, Sony has achieved high-resolution HD image quality that surpasses VGA and WVGA, which are the current mainstream resolution for battery-driven pico projectors.
Furthermore, the advanced 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. This module can project clear images to a screen size of approximately 40 inches from a projection distance of one meter, and approximately 120 inches from a distance of three meters.
Furthermore, optical technology developed by Sony has been used to achieve a reduction in laser speckle noise (noise from specks in the image), which had previously been a challenge for LBS systems.
This module also delivers beautiful, crisp projection with a wide color gamut and higher contrast compared to conventional panel systems. In addition, it is equipped with an independently-developed distortion correction circuit which corrects screen shapes such as rectangles that can be distorted into trapeziums when projected from certain angles to their original shape.”
