Problems solved by technology

[0006] In order to stably drive the different actuators, it is necessary to provide different gyro sensors for providing shake data to each of the different actuators and different memories for providing firmware data to the different actuators each of these, but when the camera module is provided with a plurality of gyro sensors and a plurality of memories, there is a problem that the manufacturing cost may increase and the size may also increase

Abstract

A camera module includes a gyro sensor to generate shaking data; a first driver integrated circuit (IC) to generate a driving signal to move a first lens barrel in at least one direction perpendicularto an optical axis direction, according to the shaking data; and a second driver IC to generate a driving signal to move a second lens barrel in at least one direction perpendicular to the optical axis direction, according to the shaking data. The first driver IC includes a register unit to store the shaking data transferred from the gyro sensor, and the shaking data stored in the register unit is transferred to the second driver IC.

Description

[0001] This application claims the benefit of priority of Korean Patent Application No. 10-2019-0121004 filed with the Korean Intellectual Property Office on September 30, 2019, the entire disclosure of which is incorporated by reference for all purposes at this. technical field [0002] The following description relates to a camera module. Background technique [0003] In general, portable communication terminals such as mobile phones, portable digital / data assistants (PDAs), portable personal computers (PCs), etc. have become popular for transmitting image data as well as text or voice data. In response to this trend, camera modules have been standardly installed in portable communication terminals in order to enable image data transmission, image chatting, and the like. [0004] Generally, a camera module includes a lens barrel having a lens therein and a housing accommodated therein, and includes an image sensor for converting an image of a subject into an electrical si...
