Abstract
A system to be used in a digital still camera to control zooming of the zoom lens, which uses programmed data written in a micro controller unit (MCU) instead of cams that are usually used to mechanically control zooming of the zoom lens of digital still cameras, and to control auto-focusing of the zoom lens with the very mechanism which is used for the zoom controlling by receiving electronic signals (pulses) from the MCU or electronically controlled distance measuring system of the digital still camera.
