标题: 线性CCD的曝光时间
PixelAverageVoltageError = TargetPixelAverageVoltage - PixelAverageVoltage;//偏差
if(PixelAverageVoltageError < -TargetPixelAverageVoltageAllowError)
{
   PixelAverageVoltageError = 0- PixelAverageVoltageError ;
   PixelAverageVoltageError /= 5;
   if(PixelAverageVoltageError > 10 )
      PixelAverageVoltageError = 10 ;
   IntegrationTime -= PixelAverageVoltageError;
}
if(PixelAverageVoltageError > TargetPixelAverageVoltageAllowError)
{
      PixelAverageVoltageError /= 5;
      if(PixelAverageVoltageError > 10 )
         PixelAverageVoltageError = 10 ;
      IntegrationTime += PixelAverageVoltageError;}

/*
uart_putchar(UART0,0XAA) ;//发送字节
uart_putchar(UART0,PixelAverageVoltage) ;
uart_putchar(UART0,PixelAverageVoltageError) ;
uart_putchar(UART0,IntegrationTime) ;
*/
if(IntegrationTime <= 1)
      IntegrationTime = 1;
if(IntegrationTime >= 100)
      IntegrationTime = 100;
}

这程序在计算曝光时间的原理是什么？
