三、白平衡控制单元调整 (一)室内白平衡调整在更换固体摄像器件或信号处理集成块IC304等电路后,需进行室内白平衡调整。所用的调整仪器为矢量仪或示波器。 1.将白平衡操作开关设置在“INDOOR”(室内)档; 2.用跳线连接法,将处理电路板上的基准电压参考点TP511,分别同测试点TP512和TP513相连。把检测时用的反馈色差信号箝位在特定电平上,避免反馈信号对调整数据的影响;
Third, the white balance control unit adjustment (A) indoor white balance adjustment After replacing the solid-state imaging device or signal processing IC304 integrated circuit block, the need for indoor white balance adjustment. The adjustment instrument used is a vector machine or oscilloscope. 1. Set the white balance switch to “INDOOR”. 2. Connect the reference voltage reference point TP511 on the processing circuit board to the test points TP512 and TP513 respectively using the jumper connection method. The detection of color difference feedback signal used to clamp a specific level, to avoid the feedback signal on the adjustment data;
