一种拍照装置双摄像头控制方法

Double-camera control method of camera shooting device

Abstract

The invention provides a double-camera control method of a camera shooting device. The method comprises the steps that a first DA converter is connected to a first light sensing element, and analogy electrical signals output by the first light sensing element are converted into digital signals; a second DA converter is connected to a second light sensing element to convert analog electrical signals output by the second light sensing element into digital signals; an image processing module is used for receiving image signals output by a first camera and a second camera, and the image signals are converted into digital signals; a dimming module is used for receiving the digital signals output by the first DA converter and the second DA converter, and the dimming signals are output according to a prestored data table; the first dimming signals are coupled to a first power conversion circuit, and the current value which is output to a first LED by the first power conversion circuit is controlled; the second dimming signals are coupled to a second power conversion circuit, and the current value which is output to a second LED by the second power conversion circuit is controlled.
本发明提出了一种拍照装置双摄像头控制方法,通过第一DA转换器连接到所述第一感光元件,将其输出的模拟电信号转换为数字信号;通过第二DA转换器连接到所述第二感光元件,将其输出的模拟电信号转换为数字信号;通过图像处理模块接收所述第一摄像头和第二摄像头输出的图像信号,将其转换为数字信号;通过调光模块接收所述第一DA转换器和第二DA转换器输出的数字信号,根据预存的数据表输出调光信号;将第一调光信号耦接到第一电力变换电路,控制第一电力变换电路输出到第一LED的电流值;将第二调光信号耦接到第二电力变换电路,控制第二电力变换电路输出到第二LED的电流值。
