Title:
METHOD FOR TRANSMITTING DATA IN CAMERA MODULE
Document Type and Number:
WIPO Patent Application WO/2018/221874
Kind Code:
A1
Abstract:
The present invention relates to a method for transmitting data in a camera module which transmits data necessary for camera shake correction, and the present invention comprises a first step in which each actuator movement detection element sequentially transmits the axial movement distance detection data detected through a Hall sensor in a two-wire interface manner without correction after each specified time delay, in a first transmission section in which each piece of axial movement distance detection data of the actuator has to be transmitted to a controller module for a shake correction; and a second step in which each actuator movement detection element sets just the variation between previously transmitted axial movement distance detection data and currently detected axial movement distance detection data as each piece of axial movement distance detection data with respect to each axis and sequentially transmits in the two-wire interface manner after the same specified time delay, respectively, in a transmission section after the first transmission period.
