Description
The STV0684 processor is targeted for use in CMOS digital still cameras. ST supplies complete camera reference designs which include sensor, co-processor, firmware and software drivers. The STV0684 uses a small BGA package (12 mm x 12 mm) ideal for the design of very small digital cameras. The STV0684 incorporates ST’s unique and highly performing video processor algorithms including newly improved and patented algorithms (e.g. NORA and Anti-vignetting).
