Abstract
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.
