New Scale Technologies' partner Tamron demonstrated an ultracompact autofocus and 3x optical zoom lens module for phone cameras at the 3GSM conference in Barcelona last week.
New Scale Technologies' partner Tamron demonstrated an ultracompact autofocus and 3x optical zoom lens module for phone cameras at the 3GSM conference in Barcelona last week.
The new AF 3x zoom module, driven by New Scale's patented piezoelectric Sguiggle motors, measures only 10.8 x 18.2 x 16.3mm.
Tamron, one of the world's leading manufacturers of precision optics, says the new module will offer tremendous flexibility and versatility in layout for handset manufacturers.
The world market for mobile phones cameras is forecast to be nearly one billion by 2009.
Handset makers are moving to incorporate high-end 3 and 5Mpixel image sensors in phone cameras, in order to produce image quality that rivals stand-alone digital cameras.
However, achieving that image quality also requires high-end precision optics and both auto focus and optical zoom capabilities, to project a sharp and clear image onto the sensors.
"Until now, no one has delivered a combination AF 3x zoom lens in a module this small", said David Henderson, President and Chief Technology Officer of New Scale.
"The miniature Squiggle motor has enabled Tamron to deliver high quality optics in the tiny form factor that mobile handset designers demand".
The Squiggle motor's technical advantages over other focus and zoom technologies include small sise, robustness, and low battery power consumption.
Tamron's advantages include a reputation for precision optics and established sales relationships with the world's leading handset manufacturers.
New Scale expects the Squiggle motor to be found in a significant share of next-generation handsets as part of the Tamron AF 3x zoom module.
"The engineering teams in Japan and New York worked together closely to ensure high performance of the integrated motor and precision lens assembly", Henderson said.
"We're very pleased to be working with Tamron in this exciting new market for high-resolution phone cameras".
