A new type of automatic white balance adjustment meter for color TV receivers with I^2C bus

介绍一种采用独立仪器机箱，并集白场信号发生器、测量、自动调整、显示为一体的新型I2C总线彩电白平衡自动调整仪，适合东芝TB系列、三洋LA系列等机芯的I2C总线彩电的白平衡自动调整，它在满足质量要求的前提下，具有快速（7－8s／台）和高通过率（99．6％）等特点。介绍该仪器的调整原理、硬件结构以及仿真手工调整的自动调整策略等软件设计方法。

This paper introduces a new White Balance Automatic Adjustment Tester with the I2C Bus for color TV. There are white signal generator, measure set, automatic adustment set and disply set in the tester. It can adjustes the I2C Bus used in color TV made of the Toshiba Th circuitry series or Sanyan LA cirouitry series.The best cbarateristic of this tester are speediness and high pass ratio while a cdsn level of quality require ment is ensured. This paper describes the adjustive principle, the hardware structure and the method of software design for automatic adjustment policy adjusted by manual simulation.
