Microcontrollers For Digital Single-Lens Reflex Cameras (Dslrs); Microcontrollers For Digital Video Cameras (Dvcs) - Toshiba TLCS-900 Family Product Manual

Microcontrollers for digital single-lens reflex cameras (DSLRs)

These microcontrollers incorporate high-speed AD converters to support
AF/AE control (computation), dial input, and other features suitable for the
main controller of a single-lens reflex camera.

Microcontrollers for digital video cameras (DVCs)

These microcontrollers, responsible for controlling the camera and tape deck
sections, contain large-capacity ROM to help minimizing the product size and
support various features suitable for main DVC control.
