Abstract:
A camera control circuit comprising:a control circuit which outputs a control instruction so as to control peripheral circuits, said control circuit including a first function block capable of operating in a predetermined supply voltage range and a second function block, having a computation function, capable of operating in a predetermined supply voltage range having an upper limit value lower than the first function block;a voltage-up circuit which increases a supply voltage of a battery in a supply voltage range enabling the first function block to operate so as to set a first supply voltage based on the control instruction, and which supplies the first supply voltage to the first function block; anda voltage-down circuit which decreases the first supply voltage in a supply voltage range enabling the second function block to operate so as to set a second supply voltage based on the control instruction, and which supplies the second supply voltage to the second function block.
