    • The invention aims at providing communication timing changing method and device which are capable of changing timing of communication for setting control parameters used to determine operations of analog devices in the analog devices, respectively, over to another one not impeding any of the operation of the analog devices. An interface decoder decodes a control parameter communication signal outputted from a CPU, converts the resulting signal into control parameters, and preserves the resulting control parameters in a register. Interface encoders perform timing management based on a synchronous signal received from a synchronous signal generating circuit, read out the control parameters to be set in analog devices such as an image sensor driving circuit, a sample and hold circuit, and an ADC from a register, and communicate with the analog devices at good timing during a blanking period to set the control parameters in the analog devices, respectively.
    • 本发明旨在提供通信定时改变方法和装置,其能够改变用于设置用于确定模拟装置中的模拟装置的操作的控制参数的通信的定时到另一个不妨碍模拟的任何操作的通信定时改变方法和装置 设备。 接口解码器对从CPU输出的控制参数通信信号进行解码,将结果信号转换为控制参数,并将结果控制参数保存在寄存器中。 接口编码器基于从同步信号发生电路接收到的同步信号执行定时管理,从寄存器中读出要在诸如图像传感器驱动电路,采样保持电路和ADC的模拟设备中设置的控制参数, 并在消隐期间以良好的时序与模拟设备进行通信,以分别在模拟设备中设置控制参数。

    • A parameter setting section sets a parameter stored beforehand in a parameter storage section as a parameter in an operation in an image pick-up section or an image processing section until an image pick-up start detection section detects an image pick-up start of a code. Moreover, when the image pick-up start detection section detects the image pick-up start of the code, the parameter setting section changes the parameter extracted from image information output from the image pick-up section or image information subjected to predetermined image processing in the image processing section from the parameter stored in the parameter storage section.
