BC—1型白平衡仪的原理与实践

ＢＣ－１型白平衡仪是一种光电积分式测色仪器，它通过颜色传感器获取屏幕的红，绿，蓝三条色信号，与预先存储在仪器中的标准信号值相比较通过ＬＥＤ条形显示器显示两者之偏差，用以直接指导彩电生产线的白平衡调整，仪器采用Ｉｎｔｅｌ１８０９８单片微机为系统核心，内藏信号发生器，仪器可任选红，绿，蓝作为基准色，具有基色亮度自动调整功能，该仪器的定标方法简单，快捷，可方便地存储８套基准白场标准数据，该仪器已可靠在应

Theory and Practice of Model BC 1 White balance Tester

The white balance tester is an instrument that adjusts the white balance for color TVs and displays. A new white balance tester to be used for on line monitor has been designed. It picks up the R(Red), G(Green), and B(Blue) signals for the screen by using color sensors, compares the signals with the data proviously stored in the internal memory, display their differences with LED barc. A built in TV signal generator sets the luminance of the adjusting screen to the brightness of the reference white screen automatically. A 16 bit signal chip microcomputer processes the measured values and controls the output levels of the TV signal generator.
