CAMERA IRIS CONTROLLER, DRIVING DEVICE AND ELECTRONIC DEVICE

A controller of a camera iris, a driving device and an electronic device are provided. The controller includes a signal processing circuit that generates a detected position value corresponding to a current position of the iris, based on first and second sensing signals respectively received from first and second position sensors that detects an aperture position of the iris; a control circuit, that sets a section between the first aperture position and the second aperture position to a plurality of control sections, and if a command to change the aperture of the iris is made, performing a corresponding control operation for each of the plurality of control sections to control a movement operation of the iris, based on the detected position value; and a driving circuit that generates a driving current, and provides the generated driving current to a coil to drive the iris under control of the controller. 提供了一种相机光圈的控制器和驱动设备及一种电子设备。所述控制器包括：信号处理电路，其被配置为基于分别从第一位置传感器和第二位置传感器接收的第一检测信号和第二检测信号，产生与所述光圈的当前位置相对应的检测位置值，所
