Abstract
The present invention provides a digital camera capable of reducing its power consumption. A digital camera includes a microprocessor (central processing unit), peripheral processing circuits for executing a data process on image data so as to share with the microprocessor, and a clock supplying circuit for supplying clocks to the microprocessor. In the digital camera, when the microprocessor requests the peripheral processing circuits to perform at least a part of the data process, thereby satisfying a condition such that a process to be shared and executed by the microprocessor does not exist, the clock supplying circuit stops supplying clocks to the microprocessor.
Claims14
A digital camera comprising:
- a central processing unit;
- a peripheral processing circuit for sharing a data process on image data with said central processing unit;
- and
- a clock supplying circuit for supplying clocks to said central processing unit,
- wherein said clock supplying circuit stops supplying clocks to said central processing unit when said central processing unit requests said peripheral processing circuit to execute at least a part of a predetermined data process and the condition that there remain no process parts to be executed by said central processing unit is satisfied.
