DRYOS
DRYOS (also stylized as DryOS) is a proprietary real-time operating system made by Canon and is used in their digital cameras and camcorders. Since late 2007, DIGIC-based cameras are shipped using DRYOS. It replaces VxWorks from Wind River Systems which has been used before on DIGIC II and some DIGIC III equipped cameras. DRYOS had existed before and was in use in other Canon hardware, such as digital video cameras and high-end webcams. DRYOS has a 16-kilobyte kernel module at its core and is currently compatible with more than 10 CPU types. It provides a simulation-based development environment for debugging. Canon also developed a USB- and middleware-compatible device driver for file systems and network devices, e.g. video server. DRYOS aims to be compatible with μITRON 4.0 and with POSIX. Cameras with DRYOS The following cameras are known to run DRYOS: * Canon PowerShot SX1 IS * Canon PowerShot SX10 IS * Canon PowerShot SX20 IS * Canon PowerShot SX30 IS * Canon Powe ...

DIGIC
Digital Imaging Integrated Circuit (often styled as "DiG!C") is Canon Inc.'s name for a family of signal processing and control units for digital cameras and camcorders. DIGIC units are used as image processors by Canon in its own digital imaging products. Several generations of DIGICs exist, and are distinguished by a version number suffix. Currently, DIGIC is implemented as an application-specific integrated circuit (ASIC) designed to perform high speed signal processing as well as the control operations in the product in which it has been incorporated. Over its numerous generations, DIGIC has evolved from a system involving a number of discrete integrated circuits to a single chip system, many of which are based around the ARM instruction set. Custom firmware for these units has been developed to add features to the cameras.
