Network operators offering PIXOTA include Bell Mobility (Montréal, Québec, Canada), The Carphone Warehouse Group PLC (London, England), Orange Nederland NV (Den Haag, The Netherlands) and Vodafone Group Plc (Newbury, Berkshire, England). NewBay Software also enjoys professional relationships with leading handset manufacturers, Motorola, Nokia and Sony Ericsson Mobile Communications AB (Lund, Sweden).

Scalado AB's (Lund, Sweden) PhotoFusion is a set of imaging functions which applies special effects in realtime, increasing camera phones' value and exclusivity, lessening time-to-market and offering significant differentiation to manufacturers and platform providers. Advanced capabilities allow capturing, editing, viewing and sharing of pictures, which can be stored or sent via MMS or E-mail. In essence, PhotoFusion adds high-end functionality to Symbian OS Series 60 and UIQ handsets.

From up to nine individual photos, PhotoStrip can create a single-image collage as a print-quality JPEG file. All results are visible in the display as if the object were seen through the camera lens. Image size, quality, contrast, sharpening, lens correction, color filtration and night modes are set by intuitive menu-driven commands. PhotoFusion extends advantages normally expected from megapixel cameras, creating VGA-dimensional panoramas with no visible borders or stitches.

Patented zoom and auto-focus solutions combine specialized lenses with digital light algorithms. Implemented in software, Tessera Technologies, Inc.'s (San Jose, Calif.) methodology replaces mechanical hardware and can be incorporated into sensors, ISPs, application processors or run off-line.

Recently, Tessera debuted wafer-level, chip-sized encapsulation for image sensors, which it accomplished by a series of business and technology acquisitions including Shellcase, Ltd. (Jerusalem, Israel). Shellcase CF and Shellcase RT permit Tessera's customers to assemble high-yield, low-profile camera modules for cell phones, PDAs, laptops and automotive electronics. Shellcase utilizes an innovative polymeric glass-silicon structure which allows image-sensing through the envelope, itself.
