An electronic camera that reduces the consumption of electricity when an image is displayed on an LCD and is able to perform other signal processing at a high speed. These scan lines are sequentially disposed next to each other. The input circuit sets a predetermined bias current, receives a radio frequency signal and inputs the RF signal into the mixer core. The wireless sensor reader receives and amplifies the ring signal and sends the signal to a phase-locked loop. The storage system controller sends a notification to a host system identifying the location of the block of data on the storage medium as determined by the storage system controller.
