Sony Develops a Prototype Digital Still Camera with its Cutting-Edge Miniaturization Technologies

Sony prototype

Tokyo, Japan, July 26, 2000 -- Sony Corporation today announced the development of a prototype digital still camera realized through a combination of Sony's latest miniaturization technologies. The prototype weighs a mere 26 grams, making it the world's smallest digital camera with a built-in LCD display. This miniaturization is made possible by Sony's latest IC bare-chip mounting technology (67æm electrode pitch) that integrates a "Memory Stick Duo" recording medium, a high-temperature poly-silicon LCD and a Lithium Ion Polymer battery into a single compact package.

Portable devices are increasing in importance with the emergence of the digital network era. Technologies utilized in the prototype digital still camera can be applied to various applications to realize a wide spectrum of portable devices in the future. For example, the technologies will facilitate the development of products such as wearable AV/IT devices and "Memory Stick Expansion Modules" which add AV and telecommunication capabilities to PCs and PDAs.

Technologies Used in the Prototype Digital Still Camera:

  • Bare-chip Mounting Technology: 67æm electrode pitch at closest points.

  • Recording Medium: "Memory Stick Duo" - Ultra compact media block (20mm x 31mm x 1.6mm) can be fitted together with a cartridge block for full compatibility with standard-size Memory Stick. The "Memory Stick Duo" is currently under development at 64MB.

  • Semiconductor Technology: Thin film color LCD monitor - Ultra-thin (4mm) color LCD module realized by super thin reflector and latest connection technology.

  • Battery Technology: Lithium Ion Polymer Secondary Battery - Compact-size, (21 x 38 x 6mm), lightweight (7g) and high capacity (210mAh).
