Electronic apparatus for use with removable storage medium, control method therefor, and program for implementing the method

摘要

An electronic apparatus which makes it possible to reduce start-up time for starting the electronic apparatus, without necessitating installment of a plurality of CPUs in the electronic apparatus. A main CPU 45 controls a digital camera implementing the electronic apparatus. A storage medium for storing information can be detachably attached to a connector 97 . A medium detection circuit 85 monitors a status of attachment and detachment of the storage medium to and from the digital camera, irrespective of a status of operation of the main CPU 45 . The sensed status of attachment and detachment of the storage medium is stored in a register 115 of the medium detection circuit 85.
